Objective:To investigate the change of petvic floor function in the third trimester of pregnancy and early postpartum.Methods :46 pregnant women in the third trimester in our hosprtal from July to October 2007 were randomly selected.In late pregnancy, 6 ～8 weeks and 12 ～14 weeks after delivery, the incidenca of stress urinary incontinence (SUI) and bladder neck mobility in different stage of puerperium was carried out.They were respectively given score, protectrve pad experiment, ultrasonic testing residual urine and peri-neum ultrasound examination.An anarysis on their.Results :The incidence of SUI that diagnosis by POP-Q or POP-Q combined with pat test was 47.83% ,39.13% respectively in late pregnancy group;21.74% ,15.22% in 6 ～8 weeks after delivery;17.24%.13.7g% in 12 ～14 weeks after delivery.The difference between late pregnancy group and 6～8 waeks after delivery group was statistical significance (P<0.05).There was no significantly difference between 6 ～8 weeks and 12 ～14 weeks after delivery groups(P>0.05).There was significant difference between 6 ～ 8 weeks and 12～14 weeks after delivery group while compared the bladder neck angle[(88.11± 13.36)° vs(82.17 ±10.28)°]with the bladder neck rotation angle[(21.67 ±10.64) ° vs (16.79±8.57) °].Conclusions :Pregnancy and delivery can damage the function of pelvic floor, which has certain rehabilitation after delivery.

Objective To discuss the relationship between pulse pressure and blood uric acid and the effect of simvastatin on pulse pressure and blood uric acid in aged primary hypertension (PH) patients with normal cholesterol.Methods Eighty-five patients with PH were divided into two groups randomly,routine group (using drugs only to lower blood pressure) and simvastatin group (simvastatin was added).Six months later,blood uric acid and pulse pressure was measured again.Results With the development of hypertension,there was statistical difference on pulse pressure and blood uric acid between hypertension grade 3 and grade 1 or grade 2 (P < 0.05).With the increase of pulse pressure,the trend of blood uric acid increase was distinct,and blood uric acid level was positively related with pulse pressure by correlation analyses(r = 0.87,P< 0.05).The pulse pressure and blood uric acid was decreased after treatment compared with that before treatment in simvastatin group (P < 0.05),but there was no significant difference before and dter treatment in routine group (P >0.05).There was significant difference after treatment between two groups (P< 0.05).Conclusions With the increasing of pulse pressure,there is a significant raise in blood uric acid.Blood uric acid is positively related with pulse pressure by correlation analyses.Simvastatin is a drug used to lower cholesterol,and it could also be used to reduce pulse pressure and blood uric acid in aged PH patients with normal cholesterol.

Thirty New Zealand albino rabbits of both sexes were used for the experi-ments which was (1) To observe the febrile response induced by microinjection of TNFinto the lateral ventricle; (2) To measure the PGE_2 & cAMP contents of the plasma andcerebrospinal fluid. The results showed that injection of TNF (50ng/each) into the lateralventricle did induce a definite raise of body temperature (T=0.79?0.14℃). The PGE_2concentration increased markedly in c. s. f. while that in plasma remain unchanged ascompared with the control. However cAMP lever in both, plasma and c. s. f. had nochange. These results suggested that (1) The injection of TNF into the lateral ventriclecaused a raise in PGE_2 synthesis in the brain while there was no alterations of PGE_2found in peripheral blood (2) The increase in PGE_2 didn't followed by an increase incAMP which indicated that the fever induced by TNF must have a different mechanismfrom that induced by leucocyte pyrogent (LP or In-1). PGE_2 might be involved in thefever inducing mechanism but these results don't support the hypothersis that the raiseof PGE_2 level may increase the cAMP content which in turn reduced the fever.

Osteochondral lesions of the talus are rare.The factors leading to them include trauma,chronic fatigue,family history,and idiopathic necrosis.The patients present with ankle pain,swelling,bruise,limited mobility and limp at an early stage while joint stiffness and walking and moving pain at a late stage.Normal check is likely to overlook them,resulting in delayed diagnosis and treatment.If an osteochondral lesion of the talus is suspected with negative X-ray manifestations,further radionuclide bone scan or MRI is indicated for definite diagnosis.As there is no blood supply to the talar cartilage which is relatively too small,it is difficult to treat osteochondral lesions of the talus.Early mild lesions can be treated by conservative therapy.If conservative treatment fails or the lesions deteriorate,surgery is required.This paper reviews the research progress in the treatment of osteochondral lesions of the talus.

Objective To explore the effects of Xuan Yun Ning on the plasma endothelin in pafients with vertebrobasilar ischemia.Methods 60 cases of vertebrobasila ischemia were randomly recruited into a treatment group and a control group,with 30 cases in each group.The control group was treated with Nimodipin,and the treatment group was treated with Xuan Yun Ning plus Nimodipin.Another 30 healthy persons whose age is more than 40 years were recruited for a healthy control group without any treatment The alterations of plasma endothelin were measured by radiation immunological test in the treatment group,the control group,and the healthy control group.Results The elevated plasma endothelin was significantly decreased in treatment group than the control group and the healthy control group(P＜0.05).Conclusion Xuan Yun Ning improves the blood volume by lowering the level of plasma endothelin and thus treats patients with vertebrobasilar ischemia.

Objective To investigate the clinical efficacy of acupoint application plus massotherapy for scapulohumeral periarthritis (periarthritis of shoulder). Method One hundred and two patients with scapulohumeral periarthritis were randomly allocated to treatment and control groups, 51 cases each. The treatment group received acupoint application plus massotherapy and the control group, massotherapy. Both groups were treated for three courses. The VAS score and the Neer shoulder function score were recorded in the two groups before and after treatment. Result The VAS score and the Neer shoulder function score improved in the two groups after treatment compared with before (P<0.05) and improved more in the treatment group than in the control group (P<0.05). Conclusion Clinically acupoint application plus massotherapy has a satisfactory therapeutic effect on scapulohumeral periarthritis with a certain effect on pains in the affected shoulder.

Objective To investigate the changes of the serum level of highly sensitive C-reactive protein (hs-CRP)in patients with cerebrovascular disease and its clinical significance. Methods The serum level of hs-CRP in 60 patients with acute cerebral infarction and 60 patients with acute cerebral hemorrhage and 40 healthy persons were determined.All the patients were scored by clinic neurological deficit scale(NDS),and were compared in groups. Results The serum level of hs-CRP in patients with acute cerebral infarction and with acute cerebral hemorrhage were significantly higher than that in normal controls(t=19.712 13.217 P <0.01).There was no obvious difference between the patients with acute cerebral infarction and with acute cerebral hemorrhage. Conclusion The serum level of hs-CRP was closely correlated with the severity of cerebrovascular disease.
