BACKGROUND: Improper practice during military training is likely to cause various training wounds, among which patellar tendinosis is the common one.OBJECTIVE: To explore the onset characteristics of patellar tendinosis caused by military training and incidence changes after the implementation of interventions.DESIGN:Sampling investigation.SETTING: Department of Orthopedics, Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA; Department of Surgery, Hospital of Chinese PLA Garrison in Hong Kong PARTICIPANTS: Male army soldiers aged 18-24 years were recruited from a full-time training army in August 2000 (non-intervention group) and August 2001 (intervention group). The same training program was carried out among the 2,783 soldiers in non-intervention group and 5,824 soldiers in the intervention group.METHODS: The investigation group was composed of medical workers with senior and intermediate professional titles. Uniform diagnostic standard was made before the investigation, and questionnaire survey wascombined with on-the-spot inspection on soldiers who complained about knee joint pain following training. Those who conformed to the diagnosis were inquired of their training state in detail and possible causes; meanwhile knee X-ray examination was also conducted. Soldiers in the non- intervention group were subjected to the investigation of the incidence and cause of patellar tendinosis due to fulltime training without given any preventive intervention. By contrast, soldiers in the intervention group were given preventive and therapeutic interventions and then subjected to the investigation into the interventional outcomes one year later.MAIN OUTCOME MEASURES: The incidence of patellar tendinosis in soldiers of the two groups.RESULTS: The first and second investigations were conducted on the 2 783 soldiers and 5 824 soldiers, respectively. All of them entered the rediers of the non-intervention group (the incidence of 0.61%) as compared to 15 soldiers in the intervention group (the incidence of 0.26%) (P＜0.01).tenderness. Patel1ar bone X-ray inspection on 12 of them displayed patellar ciated with run-jump training projects; 23 cases were caused by 400 mbarrier training and 7 cases by 5 km cross-country training.CONCLUSION: Patellar tendinosis during military training is mostly caused by run-jump training and can be remarkably prevented by preventive interventions.

Objective To investigate clinical efficacy of finasteride on chronic heart failure(CHF)compli-cated with benign prostatic hyperplasia(BPH)in elderly patients.Methods 100 cases of elderly patients with CHF complicated with BPH were chosen,according to the number table method,they were divided into the observation group and control group,50 cases in each group,all patients were treated according to their cardiac function to regulate anti -CHF therapy.The patients in the observation group were added with finasteride treatment,the control group pla-cebo treated patients,the measurement indexes were compared between the two groups after treatment,including pros-tate volume,N terminal pro brain natriuretic peptide concentration,creatinine,international prostate symptom score and symptom score,need operation treatment intervention,incidence acute urinary retention rate.Results After treat-ment,the prostate volume,N terminal pro brain natriuretic peptide concentration,creatinine,international prostate symptom score of symptom scores of the observation group were (23.86 ±10.27)mL,(352.63 ±72.55 )g/L, (84.0 ±11.6)mol/L,(9.3 ±4.9),those in the control group were (39.11 ±12.53)mL,(483.46 ±76.47)g/L, (99.0 ±12.8)mol/L,(13.9 ±5.6).The difference was statistically significant(t =9.47,17.56,12.33,8.48,all P <0.05);the observation group need operation treatment intervention was 16.0%,obviously less than 52.0% in the control group,there was significant difference between two groups(χ2 =21.85,P <0.05);acute urinary retention in patients with the observation group the incidence rate of 14.0%,significantly lower than 38.0% in the control group, there was significant difference between two groups(χ2 =12.83,P <0.05).Conclusion Patients with CHF compli-cated with BPH aged at the same time standard anti heart failure treatment using finasteride,significantly reduce the prostate volume,reduce the measurement indexes,and significantly reduce the rate of operation intervention patients, safe and reliable,which is worthy of clinical application.

Objective To summarize the effect of laparoscopic repair of acute gastric perforation. Methods Patients with acute gastric perforation underwent laparoscopic repair and abdominal drainage under intravenous- inhalation general anesthesia after a histological biopsy. Results Forty-six patients with acute gastric perforation were successfully operated.Of which, 6 patients with pylonic perforation, 37 patients with perforation in the front wall of gastric antrum, 3 patients with perforation in stomach body. Thirty-three cases were received frozen section biopsy, only 1 case showed a cancer in the lesser curve of stomach body. There was no complications occurred and no operative mortality in this series. Of the 45 benign ulcers patients,31 patients were discharged 7 days after the operation, 14 patients were discharged 2 weeks after medication treatment.Three months after operation the symptoms of the 45 patients disappeared totally,they had normal diet,and got body weight 1-3kg. Pathological examination showed that no malignant cell was found in 45 benign ulcer patients. The cancer patient was discharged 9 days after operation and refusing to further treatment. Conclusions Laparoscopic repair is a safe mini-invasive method, and it isn′t breach the surgical principles,it allows the patients recover quickly and with less complications. The intraoperative biopsy can prevent misdiagnosis of cancer. It is an effective treatment for acute gastric perforation and worthy to be widely used.

Objective To study the role of Ⅲb isoform of human fibroblast growth factor receptor 1 (FGFR1-Ⅲb) in PANC-1 pancreatic cancer cells. Methods The plasmid of human full-length FGFR1-Ⅲb isoform，pSVK4/FGFR1-Ⅲb, was stable transfected into cultured PNAC-1 pancreatic cancer cell lines facilitated by lipofectamine. The function of FGFR1-Ⅲb in transfected pancreatic cancer cells were examined by MTT assay, soft agar assay, cell migration assay, single cell movement assay, In vivo tumorigenicity assay. Results The basal anchorage-dependent and -independent cell growth was significantly inhibited. Additionally, FGFR1-Ⅲb expression inhibited single cell movement and in vitro invasion as determined by time-lapse microscopy and boyden chamber assay as well as in vivo tumor formation and growth in nude mice. Microscopic analysis of the xenograft tumors revealed a reduced Ki-67 labelling, lower amount of tumor necrosis and higher grade of differentiation in FGFR1-Ⅲb expressing tumors. Conclusion We identified a functional human FGFR mRNA splice variant that inhibits the transforming potential of pancreatic cancer cells.

OBJECTIVETo observe the effect of fluoroacetamide on cardiomyocytes of rat and the antidotal effect of acetamide.

METHODS4 groups of SD rats were treated with various dosages of fluoroacetamid(p.o.) and 2 groups of them were treated with acetamide(i.p.). The changes of cardiomyocytes and serum AST, LDH, CK, CK-MB and HBDH were measured at different intervals after poisoning.

RESULTSIn the group treated with fluoroacetamid 8 mg/kg. bw, serum AST[(589.58 +/- 821.72) U/L], CK[(916.78 +/- 343.55) U/L], HBDH[(504.47 +/- 148.88) U/L] raised obviously compared with control[(187.70 +/- 46.87), (755.65 +/- 498.90), (347.25 +/- 228.40) U/L respectively] (P < 0.01), and the pathological findings such as degeneration, liquefactive necrosis and filtration of inflammatory cells in cardiac muscles were observed 24 hours later, while all the male dead within 3 days. In the group treated with fluoroacetamid 4 mg/kg. bw, serum LDH and HBDH rose significantly compared with control(P < 0.01) 5 day later. On the day of 10, myocardial enzymes restored in all experiment groups with some interstitial fibroblastic proliferation. The pathological changes were reduced in the group treated with acetamide synchronously (100 mg/kg. bw).

CONCLUSIONAcute intoxication of fluoroacetamide could damage cardiomyocytes while acetamide could reduce the injury of them, but the injury was reversible. The levels of serum myocardial enzymes could be a usable index for early diagnosis.
