[Objective] To search for a new technique for incarcerated annular mixed hemorrhoids (IAMH) . [Methods] One hundred and eighteen cases of IAMH (group A) were treated by double denenate excision-ligation combined with pad preservation and 53 eases (group B) by external-exfoliation and internal-ligation. Cure rate, wound-healing time, anal function and postoperative complications were observed in the two groups. [Results] Cure rate was 96.6% in group A and 84.9% in group B; wound-healing time was (17 ? 5) days in group A and (24 ? 5) days in group B ( P

BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.

Objective To study and estimate the effective dose of interventional employees in the common cerebralvascular, cardiovascular and liver interventional diagnosis and treatment.Methods The absorbed doses of tissue or organ of anthropomorphic phantom in these three procedures were estimated by the anthropomorphic phantom experiment.The effective doses were calculated by the tissue weight factor which was given by International Commission on Radiological Protection publication 103.Results The effective doses to high, medium and low group were 24.0, 9.7,6.8 μSv for cerebralvascular interventional diagnosis and treatment, and 36.3, 29.3, 17.8 μSv for cardiovascular interventional diagnosis and treatment, and 23.9, 11.3, 5.5 μ Sv for liver interventional diagnosis and treatment, respectively.Conclusions The effective doses of high, medium and low group of interventional employees in cardiovascular interventional procedure are higher than those of cerebralvascular and liver interventional procedures.

Larvae of Schistosoma japonicum could be blocked in Oncomelania hupensis with pre-infection by larval Exorchis trematodes (Tang et al., 2008, 2009). The present manuscript reports the result of comparison between the two different developments of larval S.japonicum in O.hupensis snails with and without pre-infection by larval Exorchis trematodes. Of 300 (invader rate 26.74%) abnormal larvae of S.japonicum for 4-82 days old were found from 28 (73.7%) O.hupensis snails which were pre-infected with Exorchis eggs, their body structure were unusual and developed astray at early mother sporocyst stage. From 25 (69.4%) O.hupensis snails without pre- infection by larval Exorchis, 67 (invader rate 13.96%) normal mother sporocysts of S.japonicum for 5-61 days old in different development stages and many early or middle stage daughter sporocysts were found, in the 75th day after infection many mature daughter sporocysts and cercariae of S.japonicum were found. Different increase of lymphocyte in body tissues of snails were found from the two experimental O.hupensis snail groups.

Objective To observe the clinical effect of HuaYu TongFu KaiQiaoFang on serum homocysteine (Hcy)in patients with acute cerebral infarction. Methods Sixty cases of acute cerebral infarction admitted into the comprehensive ward and intensive care unit(ICU)of the First Affiliated Hospital of Guiyang College of Traditional Chinese Medicine from December 2010 to January 2012 were randomly divided into two groups,each group including 30 cases. The control group was given conventional treatment,and based on the conventional therapy,the treatment group was additionally given HuaYu TongFu KaiQiaoFang(a traditional Chinese medicine decoction including the following ingredients:Safflower 10 g,Chishao 10 g,Chuanxiong 10 g,Notoginseng 10 g,Angelica Sinensis 10 g, Shichangpu 10 g,Polygalae 10 g,Glauber's salt 5 g,Rhubarb 6 g),one dose a day by oral or nasal administration for consecutive 14 days. Before and after treatment in the two groups,the serum Hcy level was detected by enzyme-linked immunosorbent assay(ELISA),and the clinical efficacy was assessed by Pearson or Spearman correlation analysis to observe the correlation between neurological deficit score(NDS)and Hcy levels. Results Before treatment, the difference of serum Hcy(μmol/L)and NDS levels between the two groups was not statistically significant(both P>0.05),while after treatment,the levels in the two groups were significantly decreased in comparison with those before treatment(P<0.05 or P<0.01),and the degree of descent in treatment group was more obvious compared with that in control group(Hcy:7.78±2.51 vs. 10.18±2.41,NDS:10.60±2.25 vs. 14.60±3.70,both P<0.05). After treatment,the total effective rate in the treatment group was significantly higher than that in the control group (90.0%vs. 76.7%,P<0.05). Before treatment,the NDS was positively correlated with Hcy(r=0.675,P<0.05). Conclusion HuaYu TongFu KaiQiaoFang can significantly reduce the level of serum Hcy and improve the nerve function,thus its clinical effect for treatment of acute cerebral infarction is remarkable.

Objective To analyze the clinical and pathological characteristics of breast carcinoma in elderly female patients and to offer the standard clinical diagnosis and treatment for breast carcinoma.Methods A total of 178 patients admitted to Breast Center of Beijing Hospital from January to December 2011 were enrolled in this retrospective study.Patients were divided into non-elderly group and elderly group.Clinical features,imaging diagnosis,operation patterns and pathological diagnosis were recorded.The data were analyzed by using SAS 9.1 software.Results The patients diagnosed as breast carcinomas in BI-RAD 4-5 categories by mammography were much more in the elderly group than in the non-elderly group (82.1% vs.63.0%,P<0.05).The diagnostic accuracy rates of ultrasonography and mammography in the elderly group were comparable(P> 0.05),while in the non-elderly group,the diagnostic accuracy rate of ultrasonography was higher than that of mammography (P<0.05).The incidence of concurrent diseases was higher in the elderly group than in the non-elderly group (P<0.05).The patients undergoing breast resection operation were much more in the elderly group than in the non-elderly group (14 cases vs.3 cases,P<0.05).The pathological diagnosis analysis showed that there were no significant differences in the number of ER-positive cells and PR-positive cells,tumor size,histological grade,pathological stage between the two groups (all P>0.05).The incidence of lymph node metastasis was lower in the elderly group than in the non-elderly group (P<0.05).The percentage of Ki-67 positive cells was lower in the elderly group than in the non-elderly group (P<0.05).The percentage of CerbB-2 strongly positive (+++) cells was lower in the elderly group than in the non-elderly group (5.1 % vs.24%,P<0.05).The invasive ductal carcinoma was the major histological type of breast cancer in both two groups,but there were more mixed type and other type carcinomas in the elderly group than in the non-elderly group (P<0.05).Conclusions Ultrasonograpy and mammography have better sensitivity for breast cancer in elderly female patients.The surgical protocols are often influenced because more concurrent diseases have occurred in the elderly.There are significant differences in some prognostic factors between the two groups,which may imply a better prognosis in elderly patients.
