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.

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.

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.

Objective:To evaluate the ability of calcium hydroxide removal using different irrigation methods and the effect on canal sealing.Methods:200 human single root canal premolar teeth were prepared.Divided the teeth randomly into 2 groups(each group 96 teeth,8 as control),one group filled with chemical calcium hydroxide and another filled with finished product calcium hydroxide.7 days after,divided each groups randomly into 6 subsets and remove the calcium hydroxide in the root canal(table1).Then each subset group choose 8 teeth randomly,observed by scanning electron microscope.Other specimens were obturated by lateral condensation of cold gutta-percha with a AH-Plus sealer,stained by Indian ink and then made into transparent teeth model.Results:At the same condition,there was no significant difference between group A and group B;the results of groups associated with ultrasonic were better than groups with injection syringe.The rinse solution EDTA was the best,distilled water was the worse.Dye penetration showed that the length of dye staining was no significant difference among all groups.Conclusion:Ultrasonic and sodium hypochlorite associate EDTA is the best method to remove the calcium hydroxide.But none of the methods and rinse solution used in this experiment can remove all of the calcium hydroxide.The calcium hydroxide remained influence on the root canal sealer is not predominance.

Objective To study the development and research status of infectious diseases influ- ence in China and the academic influence of Chinese Journal of Infectious Disease.Methods Utilizing the literature metrology means,mainly based on《Chinese Journal Full-text Network Database》and《Chinese Citation Network Database》,statistics and analyses on the Cited Papers of Chinese Journal of Infectious Disease in 2000 to 2004 were made.Results The citation rate of 787 papers from 30 issues was 65.9%,citation frequencies in total were 2946 and the highest citation frequency was 245,the av- erage citation frequency was 5.7,and the rate of cited fund articles with total cited papers was 37.6% the total citation frequencies raised in the recent years and the average of influence factors was 1.281. Conclusion The Chinese Journal of Infectious Disease represents the highest level core periodical of infectious diseases in China and is one of the most important information resources in this research demesne.

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.
