The qualified rates of total coliforms (92.3%), nitrate nitrogen (93.6%) and total bacteria (94.9%) were relative low. The qualified rates of secondary water were 61.3%, 88.7%, and 84.5% in 2012, 2013, and 2014 respectively, which in 2012 was significantly lower than those in 2013 and 2014 (P﹤0.05). There was no statistical significance between secondary water and municipal water(P >0.05). There was statistical significance between wet and dry seasons about the qualified rate of secondary water(P﹤0.05).Conclusion Water quality of secondary water is generally good in recent two years in the troops stationed in Beijing, but some measures should be taken to be further improve water quality of secondary water .

Objective To evaluate the effects of the compound codonopsis on cognitive function of mice exposed to hypobaric hypoxia.Methods A total of 36 adult male KM mice were randomly divided into three groups by weight (n=12) : normoxia control (NC), hypobaric hypoxia (HH), hypobaric hypoxia supplementation with the compound codonopsis (HHC). The animals of groups HH and HHC were exposed to hypoxia in a specially designed decompression chamber for 28 days. The desired altitude (5500 m) was reached at a rate of 15 m/s and maintained from 9.00 a.m. to 5.00 p.m. every day. Cognitive performances were examined by open field, passive avoidance and initiative avoidance tests.Results The movement capability and exploratory behavior of mice in HH group declined compared with NC group (P<0.05), while these capability and behavior of mice in HHC group were significantly higher than those in HH group (P<0.05). In the passive avoidance test, the latency to the dark department of mice in HH group (123.2?06.7 s) was distinctly shorter than controls (230.5?7.9 s) (P<0.05), but the latency in HHC (214.4?13.7 s) was significantly extended compared with HH group. In the shuttle box test, the active avoidance latency of the three groups showed "up-down" trends. The active avoidance latency of HH group was significantly increased in comparison with controls, while the latency of HHC mice become shorter after supplementation with the compound codonopsis (P<0.05). Conclusion Hypoxia exposure can impair learning and memory of mice, and the compound codonopsis can improve cognitive functions of hypoxia mice.

Objective To observe the clinical efficacy of household noninvasive ventilator combined with the respiratory function exercise on chronic obstructive pulmonary disease (COPD) with type II respiratory failure patients.Methods A total of 54 COPD with type II respiratory failure patients were randomly divided into conventional treatment group and strengthen treatment group. Two groups both received home noninvasive positive pressure mechanical ventilation therapy, while the strengthen group had respiratory function exercise every day. After 1 year follow-up visit, modified British Medical Reseach Council (mMRC) and COPD Assessment Test (CAT) were used to evaluate patients' symptoms, 6 min walk distance(6MWD) to evaluate patients exercise endurance. Blood gas index, pulmonary function, vital signs change, rehospitalization rate and patients' prognosis were observed at the same time.Results The changed value of 6MWD in strengthen group (73.3 m) is greater than the minimum clinical significant difference value (54 m), and MRC score and CAT score in strengthen group were also improved significantly compared with before treatment (P<0.01). FEV1%, blood gas index and hospital admission again were obviously improved compared with before treatment in both two groups (P<0.05).Conclusion For the severe and very severe COPD patients with hypercapnia, long-term home noninvasive positive pressure ventilation therapy can reduce the carbon dioxide retention and hospitalization frequency. Respiratory function exercise combination with long-term home noninvasive positive pressure ventilation therapy can significantly improve exercise endurance and quality of life.

Objective To assess the status of disability and dementia among elders in China with their instrumental activities and cognitive ability and studied the current situation of the long-term care services that they received, in order to provide basis for developing a long-term care system in our country.Methods Using the Chinese Longitudinal Healthy Longevity Survey (CLHLS) as source data, KATZ Scale and MMSE Scale were adopted to assess the status of the disabled and demented elder populace. Descriptive analysis was performed by SPSS19.0 and the long-term care needs of the disabled and demented elders were analyzed. Results The disability rates of 65~79 years old, 80~89 years old, 90~99 years old, and above 100 years old elders were 5.5%, 15.6%, 34.1%, and 51.7% respectively, the dementia rates were 4.8%, 17.1%, 36.3%, and 56.6% respectively. After adding weights to the data using 2010 Chinese population census data, the results was calculated. In urban area, the disability rates of male and female elders was 10.5% and 11.2%; in sub-urban area, male 7.5% and female 8.1%; in rural area, male 5.2% and female 8.0%. In urban area, the dementia rates of male and female elders was 7.4% and 7.1%; in sub-urban area, male 4.2% and female 7.9%; in rural area, male 6.1% and female 10.8%. The family care could no longer be sufficient to meet the elders' needs with the continuous deepening of disability or dementia of the elder in some families. However, being in the low-income group, elders could not afford the high costs of care taking from social services.Conclusion It is not rare to see disability or dementia among elders, especially senior elders. With the continuous weakening of the family care, it is very crucial to build a better social long-term care system for the disabled and demented elders at state and government levels.

Except for self-care and sociality recession, the other scores of SSPI had statistically significance between two groups (P<0.05).Conclusion The programed health instruction in department of psychiatry can release some symptoms effectively and make the patients realize their morbid state more clearly to improve the patients' impaired social function efficiently.

Objective To investigate the mental health status of long-term navigation crews in nuclear submarine and to analyze the related influencing factors.Methods A total of 126 crews were investigated by Symptom Check List 90 (SCL-90) and Eysenck Personality Question (EPQ) at sealing stage and after three long-term navigations.Results The scores of factors in SCL-90, except for interpersonal relationships, paranoia and psychopathy, had significant differences compared with the norm of China soldiers. After the long-term navigation, the psychoticism (P) and neuroticism (N) scores of EPQ were obviously higher than those at sealing stage. There were no difference in scores of extraversion and gloss between before and after navigation.Conclusion The psychological health of nuclear submarine crews is at low level because of the special living and operating environment. It is necessary to take some intervention studies to protect the crews' mental health according to the character of nuclear submarine long-term navigation.

Objective To investigate the state of training injury during high altitude training of Xin-jiang artillery troop.Methods The military surgeons monitored and diagnosed of military training injury through clinic and round service, carried out case investigation and filled in questionnaires for high altitude training injury patient.Results During the high altitude training,the incidence of training injury was 10.5%, shown as special environmental injury > soft tissue injury > bone and joint injury > organic damage;The priod of the third to fourth week was the first peak of the military injury; The main crowds were the soldiers; Injury part from high to low in turn was: the upper limbs, head, lower limbs, waist abdomen and pelvis.Conclusion The training injury incidence of Xinjiang artillery troop was not higher than any other plateau and plain troops. Acute high altitude reaction and artillery professional training injury were mainly protection; The pro two weeks after training and day and night march and actual combat training in the intermediate stage and October the inspection before acceptance were the key protection time. On the protection strategy, we should strengthen the safe protective measures of training and enhanced propaganda and education on special plateau environment and protective technique with psychological diathesis.

Objective To investigate the state of training invaliding during high altitude military training in an unit army of Xinjiang.Methods The military surgeons of the medical care assurance unit diagnosed the training injury and diseases through clinic and round service and registered according to the <OPD registration form>. The investigator received invaliding information from the military surgeons.Results During the high altitude training, the occurrence rate of training injury was 35.2%, including soft tissue injury (accounted for 67.5% of training injury), bone and joint injury (16.7%), special environmental injury(11.7%). The occurrence rate of training injury was higher in 1 week - 8 weeks after entering the plateau, especially in 3-6 weeks, then decreased gradually in following 6 weeks, and it was the lowest in 2 weeks before the evacuation. Day and night incidence of diseases was 12.7%, showed as upper respiratory tract infection(40.4%), oral and other facial features division disease(24.2%), gastrointestinal disease(19.4%), dermatosis (8.8%). The time distribution of the diseases was the highest in the first 2 weeks, then gradually decreased, and increased lightly in the last 2 weeks.Conclusion During the troops carried out military training at high altitude in short period, training invaliding incidence is high, and medical institutions should supply the medical support of medicine and equipment to prevent the training invaliding.

Objective To investigate the invaliding characters of a Military Medical University new students during their long foot march, and to explore sanitary and antiepidemic supporting measures.Methods On the basis of the medical treatment records during the period of 300 km foot march, we used SPSS 20.0 data entry and analysis methods to raise the concrete measures according to this sanitary and antiepidemic programs and literature collection.Results The visit rate of freshmen having treatment was 250.02% (1351/540), including foot bubble, upper respiratory tract infection, gastroenteritis, abrasions, soft tissue injuries, which account for 77.47% of all diagnosis and treatment. Besides, the treatment people with different invalidings had time characteristics in some degree.Conclusion The invaliding spectrum of the long march on foot was specific and we should take health education in advance before military training and formulate sanitary and antiepidemic supporting measures to strengthen the ability to handle emergency medical events and prevent training invalidings according to the sanitary-epidemiological investigations and disease surveillance.

Objective To study the effect of extracorporeal shock wave on the injury of triangular fibrocartilage complex in wrist induced by military training.Methods Fourteen out-patient cases accepted extracorporeal shock wave therapy in the pain point and the around of the wrist with 1.5-2.5 Bar impact pressure, 10 times/second, 3000 impacting times, once a week, for 4 weeks. Mayo scores and Visual Analogue Scale (VAS) were taken to evaluate the therapeutic effect.Results After the treatment, the mayo scores were improved significantly, and the therapeutic effect included 9 excellent cases, 3 good cases, and 2 moderate cases. Compared with the pretherapy, the VAS decreased obviously (P<0.05). The total effective rate of extracorporeal shock wave on the injury of triangular fibrocartilage complex was 100 % in all 14 cases. Follow-up visit lasted for half a year with no recurrence.Conclusion Extracorporeal shock wave has significant therapeutic effect on the injury of triangular fibrocartilage complex, with operation easily and no adverse reactions.
