Since congenital clubfoot is not a single or uniform entity, one cannot expect a consistently favorable response from a single or uniform method. And one person's ideas or methods of therapy either conservative or operative would be noted insufficient or not applicable to all cases. This report is based upon analysis of records for 44patients seen at National Medical Center from 1971 to 1980. 44 patients with 68 congenital clubfood were seen at the Outpatient Department and 26 in-patients with 40 congenital clubfoot were treated, and the average follow-up period was II. 6 months. If the clubfoot was found early conservative method was applied initially whether it was the flexible or rigid type, and surgery was applied in children whose deformith had not responded to conservative treatment or had been neglected for a long time and proved to be rigid. The results were as follows, 1. Among 68 clubfoot, equinovarus was 64, and calcaneovalgus was 4. Of the 44 patients, 32 were male and 12 were female (2.7:1). 2.Bilaterat involvement was in 24 and unilateral in 20 patients. 3. 35 cases(79. 5%) were idiopathic, and 9 were associated with other congenital abnormalities. Of 40 clubfoot, supple type were 24 feet. and rigid type were 16 feet. In patients under 3 months of age, conservative treatment was found to be quite adequate to obtain good result. 5. 24 feet were treated with a serial cast for the average period of 8 weeks, with the result of 18 good, 3 fair, and 3 poor. To obtain good result, patient's tolerance, parent's eooperation and doctor's skill were all necessary. 6. 18 feet graded good had T-C index of more than 47. Surgical correction was applied in l6 feet of rigid type with the result of 10 good, 2 fair, and 2 poor. Various surgical methods were to be applied according to the age of patients and the main pathology. 8. Modified Turco operation was performed ia 8 patients(6 feet) at the age of 6 months, 8 months and 10 months respectively, and this one stage posteromedial release with K-wire fixation showed the best results in those age groups.

AIM: To compare the peripapillary retinal nerve fiber layer ( RNFL ) thickness and peripapillary topographic map's parameters between amblyopic eyes and non -amblyopic eyes in adolescent with anisometropic amblyopia by optical coherence tomography(OCT).
METHODS: Thirty - four juveniles with anisometropic amblyopia were selected. Peripapillary RNFL thickness and peripapillary topographic map were measured by frequency domain OCT with both eyes in all participants, and the differences between amblyopic eyes and non -amblyopic eyes were compared.
RESULTS: There was no significant difference in average thickness of peripapillary RNFL and in any other region of peripapillary RNFL. The disc area in amblyopic eyes was bigger than that in non - amblyopic eyes ( t =2. 8054,P= 0. 0263). The disc area in amblyopic eyes were significantly related to the thickness of nasal RNFL and the rim area(r= 0. 7592,0. 7501;P= 0. 0289,0. 0321).
CONCLUSION: There existed some difference in peripapillary structure between amblyopic eyes and non-amblyopic eyes in adolescent with anisometropic amblyopia.

The surveillance of schistosomiasis in three sites of Mianzhu City after earthquake showed that there were no infected Oncomelania snails and cases,but the emerging area with snails were 7 895 m~2.Therefore,the control measures should be strengthened.

OBJECTIVETo investigate the effect of tanshinone II(A) on the expression of different components in the renin-angiotensin system of left ventricles of renal hypertensive rats.

METHODThe renal hypertension model was established in rats by the two-kidney-one-clip (2K1C) method. In the experiment, all of the rats were randomly divided into four groups (n = 15 per group) before the operation: the sham-operated (Sham) group, the hypertensive model (Model) group, the low-dose tanshinone II(A) group and the high-dose tanshinone II(A) group. At 5 week after the renal artery narrowing, the third and fourth groups were administered with 35 mg kg(-1) x d(-1) and 70 mg x kg(-1) x d(-1) of tanshinone II(A), respectively. The blood pressure in rats was determined by the standard tail-cuff method in each week after the operation. After the drug treatment for 8 weeks, all the rats were put to death, and their left ventricles were separated to determine the ratio of left ventricle weight to body weight (LVW/BW), the myocardial collagen content, and the expressions of different components in myocardial RAS, including angiotensin converting enzyme (ACE), angiotensin converting enzyme 2 (ACE2), angiotensin 1-type receptor (AT1R), Mas receptor mRNA expression and angiotensin II (Ang II) and angiotensin (1-7) [Ang (1-7)] content.

RESULTCompared with the sham group, the hypertensive model group exhibited a markable increase in the content of Ang II and Ang (1-7) and the mRNA expressions of ACE, ACE2, AT1R and Mas (P < 0.01). However, the treatment with tanshinone II(A) showed the does dependence, inhibited left ventricle hypertrophy, decreased myocardial Ang II content and the mRNA expression of ACE and AT, R in renal hypertensive rats (P < 0. 01) , further increased the myocardial Ang (1-7) content and the mRNA expression of ACE2 and Mas (P < 0.01) , but without any change in the blood pressure of hypertensive rats.

CONCLUSIONThe treatment with tanshinone II(A) could inhibit left ventricle hypertrophy of renal hypertensive rats. Its mechanism may be partially related to the expression of different components in the renin-angiotensin system for regulating myocardial tissues.

Objective To investigate the expression and role of Caspase-3 during the development of non-traumatic avascular/aseptic necrosis of femoral head(ANFH).Methods Tissue samples were obtained from 22 femoral heads of 21 patients with ANFH.The samples were divided into three groups:early stage(6 cases),middle stage(8 cases) and late stage(8 cases) groups according to the progress of the disease.Meanwhile,19 tissue samples of 19 femoral heads were obtained from 19 cases of acute femoral neck fracture and set as a control group.The level of apoptosis of each group was compared in terms of the percentages of TUNEL positive osteocytes and empty osteocyte lacuna,and then the activity of Caspase-3 was detected by colorimetric method.Results Both the pecentages of empty osteocyte lacunae(F=45.43,P=0.000) and the TUNEL positive osteocytes(F=120.86,P=0.000) increased significantly with the progress of ANFH.The two indexes in the early and middle stage groups were significantly higher than those in the control(q=18.899,P0.05).Caspase-3 activity was not significantly related to the capacity of osteogenesis(r=0.126,P=0.425).Conclusions Caspase-3 is not the major executor of apoptosis in ANFH.It is very likely that it does not play a nonapoptotic role in the progress of the diseases.

Objective To explore the value of predicting ovarian response using the antral follicle count in in vitro fertilization(IVF) cycle. Methods 54 patients in our infertility treatment center were observed, in which 6 patients had poor ovarian response and the other 48 patients had good ovarian response. The clinical data, duration and efficacy of treatment were compared between the two groups. Results The mean number of antral follicles and retrieved oocytes in the third day of menstruation in good ovarian response group was significantly higher than that in poor ovarian response group. The clinical pregnancy rate of the good ovarian response group was better than that of the poor one. Conclusions Monitoring the antral follicle count in both ovaries using vaginal ultrasound may predict ovarian response in IVF in the third day of menstruation.
