Objective To investigate the prevention of re-adhesion after high dose estradiol valerate and hysteroscopy regular inspection after separation of severe intrauterine adhesions.Methods A total of 97 severe intrauterine adhesions patients after transcervical resection of adhesions were divided into group A,B,C:group A placed intrauterine device and oral intook progynova 1 mg/d after 2 days of surgery,3 times/d,for 3 months; group B placed intrauterine device and oral intook progynova 3 mg/d after 2 days of surgery,3 times/d,for 3 months; group C with the same treatment as group B with further hystemscopy regular inspection every month.Regular follow-up data were collected in the following 3 months to compare endometrial thickness,re-adhesion occurrence and treatment effect in different groups.Results After 3 months of treatment,endometrial thickness of group B and group C was higher than that in group A [(0.83 ± 0.23),(0.99 ± 0.28) cm vs.(0.54 ± 0.18) cm],group C was higher than group B,and there were significant differences (P＜ 0.05).The effective rate in group B and group C was higher than that in group A [75.00％(24/32),90.32％(28/31) vs.61.76％(21/34)],group C was higher than group B,and there were significant differences (P＜ 0.05).The occurrence rate of re-adhesion in group B and group C was lower than that in group A [21.88％(7/32),9.68％(3/31)vs.38.23％(13/34)],group C was higher than group B,and there were significant differences (P ＜ 0.05).Conclusion The prevention of re-adhesion after high dose estradiol valerate and hysteroscopy regular inspection is effective and superior.

Objective To study the length of hypertension history and its related factors in patients with both ischemic cerebral vascular disease(ICVD) and hypertension.Methods The profile of hypertension history in ICVD patients from our hospital between 1990 and 1999 was summarized.Hypertension history meant the time interval between onset of first symptomatic ICVD and establishment of diagnosis of hypertension.The related factors' influence on the length of hypertension history was analyzed by means of multiple linear regression model.Results In ICVD patients with hypertension,the mean length of hypertension history was 14.29?10.63 years,the median was 11 years.In multiple linear regression model,increased age when hypertension was diagnosed,diabetes mellitus,smoking,peasant(army man as control group) were independent factors that shortened hypertension history.Antihypertensive treatment independently lengthened hypertension history.Conclusion The length of hypertension history varies greatly,50% of patients developed the first ICVD in 11 years after the diagnosis of hypertension was established .Coexisting smoking and diabetes mellitus hasten while control of arterial blood pressure postpone onset of ICVD in patients with hypertension.

There is a complicated association between the liver and diabetes mellitus.Diabetes mellitus may cause various forms of liver damage,such as nonalcoholic fatty liver disease (NAFLD),hepatic cirrhosis,hepatocellular carcinoma,liver abscess,and liver transplant complications.With the growing epidemic of diabetes mellitus,this review investigates diabetes mellitus induced liver damage.

BACKGROUND:Bone formation and development are reported to be regulated by bone morphogenetic protein2(BMP2)-induced Osterix expression. OBJECTIVE:To investigate the regulatory effect of BMP2/Osterix signaling pathway on differentiation of preosteoblasts in mice. METHODS:mRNA and protein expression of Osterix wasdetermined by real-time RT-PCR and western blot assay, respectively at various time points after mouse preosteoblasts were treated with BMP2. pcDNA3.1/myc-Osterix eukaryotic expression vector was constructed and transducted into preosteoblasts, and then mRNA expression of alkaline phosphatase, bone sialoprotein, and matrix extracelular phosphoglycoprotein wasdetected by real-time RT-PCR after transduction and BMP2 treatment. RESULTSANDCONCLUSION:Osterix mRNA expression was up-regulated when treated with BMP2 in mouse preosteoblasts, and reached the peak at 24 hours. In addition, the protein expression of Osterix was increased after BMP2 treatment. Alkaline phosphatase, bone sialoprotein, and matrix extracelular phosphoglycoprotein mRNA expression wasup-regulated after transfection of mouse preosteoblasts with pcDNA3.1/myc-Osterix eukaryotic expression vector and BMP2 treatment. Our results indicate that BMP2 regulates the synthesis of genetic markers of osteogenesis,such asalkaline phosphatase,matrix extracelular phosphoglycoproteinviaup-regulating Osterix expression in mouse preosteoblasts, suggesting BMP2/Osterix signaling pathway plays a critical role in bone development.

Objective To study the pattern of cellular proliferation and apoptosis in different part of colorectal cancer and its relation to patients' prognosis. Methods The expression of PCNA and Fas protein were investigated by immunohistochemistry in cancer mucosa, cancer adjacent mucosa and cancer distant mucosa of 76 cases of colorectal cancer, and the patients prognosis were investigated too. Results The PCNA expression in cancer mucosa is significantly higher than that in cancer adjacent tissue(P

0.05) respectively.Conclusion:Distraction osteogenesis can be used for alveolar ridge augment and for the application of dental implant.

The original methods on DNA extraction are not only complex and expens ive, but although invalid with actinomycetes under extreme environments Genomi c DNA can be extracted directly from biomass picked up from solid medium by micro wave thermal shock The extracted DNA is suitable for PCR The method is effec ti ve, easy and fast, and can be used in actinomycete systematics and identificatio n rapidly

ObjectiveTo investigate the clinical effects of systems integrative rehabilitation therapy for cervival spdylotsis myelopathy.MethodsFrom April 2002 to October 2004, 68 cases were intervened with the integrative rehabilitation treatment, which linked up the pre- and post-operational rehabilitation interventions into a continuum. The cases were followed up, and serial radiological evaluations were applied. Then the height of involved interspinal space was measured preoperatively and 12 months after operation, and the spinal function was evaluated according to the standard of Japanese Orthopeadic Association (JOA).ResultsAll the cases were followed up, of which 49 were better, 1 was improved, none was worsened. 12 months after operation, roentgenographic appearance showed that the allograft healing and interbody fusion of all patients were achieved, and the reserving height of involved interspinal space and JOA evaluation postoperatively were significantly superior to preoperatively. There was no complications such as cervical spinal cord injury, internal fixation loosening and hematoma turned up.ConclusionThe integration rehabilitation therapy has satisfactory effects in the cervical spondylotsis myelopathy.

Objective: To observe the effects of tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder on pain and shoulder joint function in subacromial impingement syndrome (SIS). Methods: Eighty patients with SIS were recruited and divided into a control group and a treatment group by the random number table method, with 40 cases in each group. The control group was given JIN's three-needle therapy for the shoulder, and the treatment group received additional tendon-regulating and stretching manipulation. The visual analog scale (VAS) score and constant-Murley score (CMS) were observed before and after the intervention, and the total effective rate was also observed. Results: The total effective rate was 92.5％ in the treatment group versus 70.0％ in the control group, and the difference was statistically significant (P<0.05). The VAS score and CMS changed notably after treatment in both groups (P<0.05), and the improvements were markedly greater in the treatment group than in the control group (P<0.05). Conclusion: Tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder can facilitate the relief of pain and the improvement of shoulder joint function in SIS patients.
