[Objective]To explore the incidence, causes, training courses at high risk and location of the body of training injury in a special force corps, provide evidence for effective prevention of the injury.[Method]A questionnaire on training injuries and relative situations, and review of medical records from Nov 2005 to Oct 2006 were performed in 823 soldiers and officers in a special force corps at Nov 2006. Data were input into computers after quantization, and descriptive analysis was conducted with SPSS 13.0 software. [Result]Of 823 soldiers and officers, 738 (89.67%) experienced one or more injuries in that year, 525 (63.79%) were affected in normal training, 221 (26.85%) lost more than one training day due to the injuries. Confirmed with the medical records, 213 (25.90%) lost more than one training day due to injuries. A total of 1696 injuries occurred in 823 soldiers and offices in that year, of them, 1263 injuries interfered with normal training. Injury rate was 12.78 per 100 per month. 24.12% of injuries were due to over-exertion, 15.86% due to accident and 13.33% due to environmental field. Injury occurred mainly in runing related training courses including 5km running (22.17%) and 400m obstacle running (20.87%), followed by weight lifting (9.67%). The most frequent site of injury was the lower extremities, accounted for 65.74 % of the inj urie s including the foot ( 18.75 %),the ankle (13.50%), the leg (13.56%) and the knee (14.39%), followed by low back (14.21%). [Conclusion]Persistent over-exertion basic training, the courses at high risk of injury, should be improved in focus. Lower extremities and low back, the most frequent locations of injury, should be taken as key points of prevention and treatment of training injury.

OBJECTIVETo observe clinical efficacy of plum-blossom needle for follicular maldevelopment (FM).

METHODSFifty cases of FM were randomly divided into a plum-blossom needle group and a medication group, 25 cases in each one. In the plum-blossom needle group, the plum-blossom needle was applied along Thoroughfare, Conception, Governor and Belt Vessel as well as at Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23), Luanchao (Extra), Zigong (EX-CA 1) during the follicular growth phase, once every other day. In the medication group, clomifene (CC) was prescribed for oral administration and human choriogonadotropin (HCG) was given by intramuscular injection, once each day. For both groups, one menstrual cycle constituted one course. After two courses of treatment, follicular development condition, the changes of endometrial thickness and morphology, ovarian resistent index (RI) and pulsatility index (PI), rate of ovulation and pregnancy were compared between the two groups.

RESULTSAfter the treatment, the average diameters of the biggest follicle increased in both groups, while the endometrial thickness and morphology in the plum-blossom needle group were superior to those in the medication group (all P < 0.05). Ovarian RI and PI during mature follicular phase in the plum-blossom needle group were inferior to those in the medication group (both P < 0.05). The differences in ovulation and pregnancy rate were not significant statistically between the two groups (both P > 0.05).

CONCLUSIONThe plum-blossom needle therapy based on regulating Thoroughfare, Conception, Governor and Belt Vessel could improve the ovarian blood perfusion, promote the follicular growth, increase the ovulation rate of mature follicle and avoid the out-of-sync between growth of follicle and endometrium during the treatment of western medication.

Objective To prepare recombinant human epidermal growth factor (rhEGF) sustained-release microspheres and evaluate their morphology, rhEGF releasing activities and cell proliferation activity in vitro and compare difference of rhEGF sustained-release microspheres and rhEGF in facilitaring ulcer healing in diabetic rats. Methods (1) rhEGF sustained-release microspheres were prepared by the modified double emulsion method. Morphology of the microspheres was detected by transmission electron microscope and size distribution measured by laser granularity meter/Zeta electric potential meter. ELISA assays were applied to determine rhEGF releasing. (2)Proliferation of mouse fibroblasts was analyzed by MTr method. (3) Diabetic rat models were prepared and divided into four groups, ie, rhEGF sustained-release mierospheres group (Group A), rhEGF stock solution group (Group B), blank sustainedrelease mierospheres group (Group C) and PBS meustruum control group (Group D), which were given drug once a day. The wound healing rate was calculated by taking photographs at days 3,7,14 and 21. Skin specimens from the wound edge were harvested partially for observation of hydroxyproline (HYP) contents. Immunohistochemistry was employed to detect integrin 131 and keratin-19 and measure their positive staining area ratio. Results (1) The particle diameter of rhEGF sustained-release microspheres was 193.5 nm, with relative uniform particle diameter distribution. There showed no conglutination among rhEGF susrained-release microspheres, with good dispersibility. Releasing drug lasted for 24 hours and accorded with Higuchi release kinetic model. (2) Different concentrations of rhEGF sustained-release microspheres could promote the proliferation of mouse fibroblast, especially the concentration of 10 μg/L (P <0.05, compared with the control). (3) From the 7th day after treatment, Group A had the fastest wound healing rate, with statistical difference compared with other three groups (P < 0.05). Group A had higher HYP contents and positive area ratio of integrin β1 and keratin-19 than Group B. Conclusions rhEGF sustained-release microspheres prepared by the modified double emulsion method have uniform particle size and can last release for 24 hours. Compared with rhEGF stock solution, rhEGF sustained-release microspheres have faster and better ulcer healing and higher healing quality in diabetic rats.

Objective　To investigate the effects of glucagon-like peptide 2 (GLP-2) on recovery of small intestinal epithelia from radiation injury in mice. Methods　Mice received a single 8 Gy dose of total body irradiation from 60Co gamma ray followed by treatment with GLP-2 or vehicle. DNA and protein content in small intestinal mucosa were measured, and small intestine was processed for histological examination with light microscope and scanning electron microscope. Results　Small intestinal mucosal DNA and protein content, villus height, and villus number significantly decreased in irradiated mice, partial villus tips were ulcerated. GLP-2 administration caused increase in DNA and protein content, villus height, and villus number as compared with irradiated control group. Meanwhile, the villus tips were lack of ulceration. Conclusion　GLP-2 can promote recovery of small intestinal epithelia from radiation injury in mice.

Objective　To study the effect of glucagon-like peptide 2 (GLP-2) on mitogen-activated protein kinase (MAPK) activity in small intestinal epithelia in mice after radiation injury and its relation with the change of small intestinal epithelial proliferation. Methods　Mice were given a single dose of 8 Gy of total body 60Co gamma irradiation and then divided into GLP-2 and control groups. The activity of MAPK and proliferation rate in small intestinal epithelia were measured. Results　The activity of MAPK in small intestinal epithelia was higher in GLP-2-treated mice than in irradiated mice, and the proliferation rate in small intestinal epithelia significantly increased in GLP-2-treated mice. These two indices were of significantly positive correlated. Conclusion　GLP-2 can promote small intestinal epithelial proliferation in irradiated mice, and this may be related to activation of MAPK in small intestinal epithelia.

Objective To analyse the clinical effect and safety of Alimta (Pemetrexed) combined with cisplatin treatment (PP) on elderly patients with non small cell lung cancer (NSCLC).Methods We retrospectively analyzed the clinical data of 40 cases of NSCLC patients treated with Pemetrexed combined with cisplatin for first-line chemotherapy,and 24 cases of them continually received single Pemetrexed for maintenance treatment (PP + C).Then we compared the results with 35 patients in the non-Pemetrexed regimen (control group) and 26 patients with best supportive care (BSC) in the same period.The adverse reactions and short-term efficacy [response rate (RR),disease control rate (DCR)] were evaluated.Time to progression (TTP),median survival time (MST),one-year and three-year survival rates and follow-up overall survival (OS) were calculated.Results Among 40 patients with Pemetrexed regimen,2 patients had complete remission (CR),and the RR was 47.8％,which was better than 42.8％ (P =0.026) in the control group.The main adverse reactions of pemetrexed regimen were myelosuppression,fatigue,nausea and vomiting,but all were tolerated and no treatment-related death occurred.24 patients received single Pemetrexed maintenance therapy.The MST of the PP + C group was superior to the other groups (P =0.03,P ≤0.05);the median OS of the PP + C group,the control group,and the BSC group reached 13.2,10.4 months and 8.6 months,respectively (P ≤ 0.001).Conclusions For elderly patients with advanced NSCLC,especially adenocarcinoma,the combination of Pemetrexed and cisplatin is a better treatment option.It is convenient to administer and has less toxicity and adverse reactions related to chemotherapy.Patients with better PS score after first-line treatment can obtain longer survival period after maintenance treatment.

This study is to observe the effect of salvianolic acid B (Sal B) on neural cells damage and neurogenesis in sub-granular zone (SGZ) and sub-ventricular zone (SVZ) after brain ischemia-reperfusion (I/R) in rats. A modified middle cerebral artery occlusion (MCAO) model of focal cerebral ischemia-reperfusion was used. The rats were divided into four groups: sham control group, ischemia-reperfusion group, Sal B 1 and 10 mg x kg(-1) groups. Sal B was consecutively administrated once a day by ip injection after MCAO. The neurogenesis in SGZ and SVZ was investigated by BrdU method 7 days after MCAO. The Nissl staining for neurons in the hippocampal CA1 and cerebral cortex was performed 14 days after MCAO. A beam-walking test was used to monitor the motor function recovery. We found that brain ischemia resulted in an increase of BrdU positive cells both in ipsilateral SGZ and SVZ at 7th day after MCAO. Sal B (10 mg x kg(-1)) significantly increased further the number of BrdU positive cells both in SGZ and SVZ (P < 0.01). Ipsilateral hippocampal neuron damage occurred and CA1 almost lost 14 days after MCAO. Sal B (10 mg x kg(-1)) obviously attenuated the neuron damage and increased the number of neuron both in ipsilateral CA1 and cerebral cortex (P < 0.01). We also observed an obvious improvement of motor function recovery when Sal B (10 mg x kg(-1)) administrated. From the results above we concluded that Sal B stimulated neurogenesis process both in SGZ and SVZ after brain ischemia, and also alleviated neural cells loss and improved motor function recovery after brain ischemia in rats.
