OBJECTIVETo observe the clinical efficacy of modified Wuhua Decoction (WHD) on corticosteroid addictive dermatitis (CsAD) and in improving patients' facial skin barrier function.

METHODSSeventy-five patients were randomly assigned to two groups, the 38 in the treated group treated with WHD together with oral administration of levocetirizine tablet, while the 37 in the control group treated with levocetirizine tablet alone in the same way, 30 days as a course. Skin erythema dose (ED) and transepidermal water loss (TEWL) of patients were measured before and after treatment.

RESULTSFive cases in the treated group and 7 cases in the control group were dropped out. The total effective rate was 69.7% (23/33 cases) in the treated group and 10.0% (3/30 cases) in the control group respectively, with the score of objective symptoms reduced from 5.48 +/- 1.60 before treatment to 1.24 +/- 1.62 after treatment and the score of subjective symptoms reduced from 7.06 +/- 1.54 to 1.55 +/- 1.72 in the treated group, while in the control group, the two indexes reduced from 5.57 +/- 1.25 to 3.27 +/- 1.55 and from 6.77 +/- 1.36 to 3.07 +/- 1.36 respectively, showing significant difference between the two groups and the efficacy in the treated group was better than that in the control group (P <0.01). Skin ED decreased significantly in the treated group after treatment, and insignificantly in the control group. TEWL began to decrease on the 15th day in the treated group, while it was unchanged in the control group; on the 30th day, although a decrease was shown in both groups, its reduction was lower in the treated group (P <0.05).

CONCLUSIONWHD has significant clinical efficacy on CsAD, it could reduce the skin ED and quickly recover the injured facial skin barrier function.

OBJECTIVETo construct an operable strategic framework for cholera prevention and control which mobilized the advantages of local resources and adapted to social developments in Chengdu, and to evaluate its application effects.

METHODS(1) After analyzing the local epidemic data of cholera in Chengdu from 1994 to 2004, we determined the main problems of cholera prevention and control works as well as the efficiency and deficiency of employed measures, and then formed a basic strategic framework. (2) After 55 invited experts preliminarily scored the strategic framework, we selected 72 specific measures to establish a measure entry database, and then the importance and operability of each measure were scored by 17 core experts. (3) Finally, the effectiveness of this strategic framework was evaluated according to the analyzing results of infection control, health education and etiological monitoring.

RESULTS(1) The framework took government leadership as main scenario and the informatization as subordination scenario. Meanwhile, it focused on three points: the improvement of social environment, the completion of system and mechanisms for monitoring and early warning, and the enhancement of CDC response to public health emergencies. Total importance score and operability score of 35 specific measures included in this framework was 4.20 ± 0.86 and 4.09 ± 0.87, respectively. (2) Chengdu had maintained zero cholera incidence for five consecutive years from 2005 to 2009 since it gradually began to implement the strategic framework in 2002. There were 19 positive cholera cases detected by etiological monitoring and all of them were seafood or fishery products including soft-shelled turtles, silver carps and bullfrogs. The coverage rate and qualification rate of the training for grassroots cadres, grassroots medical workers, mobile cooks and their assistants was 98.14% (198 452/202 220) and 98.17% (194 820/198 452) in average, respectively. The qualification rate of the training for employees in food industry was over 96.00% (912 470/950 489). The average awareness rate of cholera prevention and cure knowledge in rural residents, grassroots cadres, grassroots medical workers, mobile cooks and their assistants was 93.87% (1653/1761) and the average formation rate of good hygiene habits was 70.58% (1243/1761).

CONCLUSIONA strategic framework suitable for cholera prevention and control in Chengdu has been successfully established in this study. The incidence rate of cholera has maintained zero in Chengdu for five consecutive years under incessant threatening conditions such as the occurrence of cholera cases from time to time in its surrounding areas and the continuous existence of Bacillus comma in seafood or fishery products that entered local markets. Therefore, it demonstrated a good application effects.

OBJECTIVETo study the expression of CD20 in thymomas and its clinical significance.

METHODSOne hundred and seventy-nine cases of thymoma were enrolled into the study. The histologic diagnosis was reviewed by two experienced pathologists on the basis of the 2004 WHO classification. One hundred and two cases were selected for immunohistochemical study for CD20, pancytokeratin, TdT, CD3, CD43, CD99 and S-100 protein. The cases were further categorized into two groups, according to the association with clinical evidence of myasthenia gravis. The immunostaining pattern was then statistically analyzed.

RESULTSAmongst the 102 cases studied, 7 cases belonged to type A thymoma, 32 cases type AB thymoma, 17 cases type B1 thymoma, 15 cases type B2 thymoma, 17 cases type B3 thymoma and 14 cases thymic carcinoma. The expression rates of CD20 in neoplastic epithelial cells of type A, type AB, type B1, type B2 and type B3 thymomas and thymic carcinomas were 3/7, 84.4% (27/32), 1/17, 2/15, 0/17, 0/14, respectively. The proportions of CD20-positive lymphocytes in the background were 3/7, 18.8% (6/32), 14/17, 11/15, 11/17, 6/14, respectively. The proportion of CD20-positive intra-tumoral B lymphocytes in the group of thymomas with myasthenia gravis was 67.5% (22/40), in contrast to 35.5% (22/62) in those without myasthenia gravis.

CONCLUSIONSThe neoplastic epithelial cells in cases of type A and type AB thymoma, as well as few cases of type B1 and B2 thymoma, express CD20. The immunostain highlights the presence of oval, stellate or spindly cells. Thymomas associated with myasthenia gravis contain a significant population of CD20-positive intra-tumoral B lymphocytes. Type AB thymomas may be originated from different populations of cells, rather than a simple admixture of type A and B thymoma cells.

OBJECTIVE: To prospectively compare facial pain outcomes for patients having either a repeat microvascular decompression (MVD) or percutaneous balloon compression (PBC) as their surgery for trigeminal neuralgia (TN) recurrence.METHODS: Prospective cohort study of 110 patients with TN recurrence who had either redo MVD (n=68) or PBC (n=42) from July 2010 until September 2016. The mean follow-up was 45.6 months.RESULTS: After redo MVD, 65 patients (95.6%) experienced immediate relief of pain. After PBC, 34 patients (81%) were immediately relieved of their neuralgia. After 1 month, the clinical effect of redo MVD was better than PBC (p < 0.01). Patients who had redo MVD more commonly were pain free off medications (93.4% at 1 year, 78.2% at 4 years) compared with the PBC patients (85.1% at 1 year, 59.3% at 4 years). However, mean length of stay was longer (p>0.05). Patients after PBC who occurred developed herpes simplex (35.7%), facial numbness (76.2%), and annoying dysesthesia (21.4%) more frequently compared with patients after redo MVD who occurred developed herpes simplex (14.7%), facial numbness (8.8%), and hypoesthesia (5.9%) (p < 0.05). The symptoms recurred respectively in 15 patients (22.1%) and 19 patients (45.2%) after redo MVD and PBC within the entire 6-year follow-up period.CONCLUSION: For the patients with TN recurrence, redo MVD was a more effective procedure than PBC. The cure rate and immediate relief of pain were better, and the incidence of complications was lower.

OBJECTIVETo study the clinicopathologic features of granulocytic sarcoma.

METHODSThe clinical and pathologic findings of 38 cases of granulocytic sarcoma were retrospectively analyzed. Immunohistochemical study was performed and the literature was reviewed.

RESULTSThe age of patients ranged from 2 to 77 years (mean = 43.3 years). The male-to-female ratio was 1.5:1. Major clinical presentations included superficial lymph node enlargement and painful soft tissue mass. Follow-up data were available in 18 patients; and 14 of them died of tumor-related diseases. The average duration of survival of the patients was 16.9 months. Histologically, the tumor cells were relatively uniform in appearance and small to medium in size. The cytoplasm was scanty and pale in color. The nuclei were round or focally irregular, with fine chromatin and inconspicuous nucleoli. Mitosis figures were readily identified. Scattered immature eosinophilic myelocytes were seen. Immunohistochemical study showed that the tumor cells in all cases expressed MPO and CD43. Most cases were also positive for CD68, lysozyme, CD99 and TdT. The staining for CD3, CD20, CD79a, pan-cytokeratin and PLAP were negative.

CONCLUSIONSGranulocytic sarcoma is a known histologic mimicker of non-Hodgkin lymphoma, Ewing sarcoma/PNET and embryonal rhabdomyosarcoma. Detailed morphologic examination, when coupled with immunohistochemical study, is useful in arriving at a correct diagnosis.

OBJECTIVETo explore the feasibility and advantages of hand-assisted video-thoracoscopy for resection of esophageal cancer.

METHODSForty-five patients with esophageal cancer received hand-assisted video-thoracoscopic esophagectomy (group I). 45 patients underwent esophagectomy through routine open thoracotomy during the same period as control (group II). The data of lymph node resection, operating time and blood loss were compared.

RESULTSThere were no operative mortality in 2 groups. In group I, the number of dissected paraesophageal lymph nodes, cardiac lymph nodes and left gastric nodes were (3.6 +/- 1.0), (1.3 +/- 1.1) and (4.3 +/- 1.4), respectively. While for group II the dissected lymph nodes were (3.3 +/- 1.5), (1.6 +/- 1.1) and (4.7 +/- 2.1), respectively. There was no significant difference between two groups (P > 0.05). However, the number of dissected mediastinal nodes was (6.6 +/- 3.7) for group I and (3.8 +/- 2.5) for group II (chi(2) = 2.95, P < 0.05). The mean operating time was (29 +/- 5) minutes for group I and (60 +/- 6) minutes for group II. The mean blood loss was (93 +/- 19) ml for group I and (145 +/- 35) ml for group II. The mean chest tube drainage was (201 +/- 45) ml for group I and (295 +/- 57) ml for group II in the first postoperative day. The difference in above parameters between 2 groups was significant (chi(2) = 18.69, 6.13, 6.08, P < 0.001).

CONCLUSIONSIt is suggested that hand-assisted video-thoracoscopic esophagectomy is a safer, minimal invasive procedure in the resection of esophagus carcinoma.

Objective To study the prevalence of common infections with soil-borne intestinal nematodes amongst kindergarten children aged 3 to 6 years in Hangzhou,Zhejiang Province to provide evidence for determination of the priority of disease prevention and control.Methods Totally,1667 preschool children were selected from 14 kindergartens of Classes A,B and C in east,middle and west Hangzhou.Perianal skin Scotch Tape(a short strip of sealing cellophane pressure-sensitive tape)specimens were collected for detection of eggs of Enterobius vermicularis,and stool specimens for eggs of Ascaris lumbricoides,Ancylostoma duodenale and Trichuris trichiura by Kato-Katz method and saturated brine floatation,as well as questionnaire interview,for all the children.Results Two hundred and sixteen of 1667 children examined were found infected with common soil-borne intestinal nematodes,with an overall prevalence of 12.96%,4.44% for Enterobius vermicularis,8.28% for Ascaris lumbricoides,0.54% for Trichuris trichiura and 0.24% for Ancylostoma duodenale.Prevalence of infection of common intestinal nematodes was 7.31% in children of the Class A kindergartens,12.60% of Class B,and 21.47% of Class C,with statistically significant difference(?~2 = 49.95,P

With the continuous expansion of the domestic population flow,the medical and health services is-sues of migrant population are becoming more and more serious. Based on the three aspects of the demand,supply, and utilization of health services,this article explores and analyzes the utilization of health services for migrant popu-lation in Beijing in 2015 on the basis of behavioral models. The results showed that the prevalence of chronic diseases and the frequency of disease in migrant population are relatively low. The migrant population has low efficiency and overall evaluation of public health services. From the point of view of convenience and diversity of services,the sup-ply of public health services needs to be further improved. In terms of the active utilization of medical and health services,the proportion of respondents who did not participate in any medical insurance still have a large proportion, while the proportion of regular physical examination was lower. In terms of passive utilization,both outpatient and in-patients service use are low. Family income and medical insurance have influenced patients'choice of medical institu-tions to some extent. The health promotion strategy is proposed from the perspective of supply side and utilization.

OBJECTIVETo analyze the feasibility and the value of resection for lung cancer invading the superior vena cava (SVC).

METHODSBetween 1988 and 2005 the data of 31 patients who underwent resection were analyzed retrospectively. The reconstruction was done using simple suture, pericardial patch or prosthetic replacement. Postoperative morbidity, long-term survival were examined using the Kaplan-Meier method (Log rank test) and the COX model for survival.

RESULTSSeventeen squamous cell carcinomas, 8 adenocarcinomas, and 6 undifferentiated small cell carcinomas were resected. There were 13 partial SVC resection, the reconstruction was done using a simple running in 5 patients, and a pericardial patch in 8 patients. Eighteen patients underwent complete resection of SVC with prosthetic replacement. The time of clamping the SVC system was from 8 to 35 minutes for complete resection patients, while the time was from 3 to 15 minutes for partial resection patients. One patient didn't clamp the SVC. Postoperative morbidity and mortality were 48% and 0%, respectively. One, 3 and 5-year survival rates were 61%, 33% and 21%, respectively, with median survival at 31 months. Survival rate of patients with N2 disease was obviously lower than those with localized (N0/N1) nodal disease (chi2 = 14.3, P = 0.000), the median survival was 42 and 13 months respectively. There were no significant effects on overall survival with pathologic features and surgery methods. Survival rate of patients with induction chemotherapy before operation or intraoperative chemotherapy was higher than those received direct surgery (chi2 = 5.0, P = 0.025), the median survival was 39 and 14 months respectively.

CONCLUSIONSThe resection of the SVC for involvement by lung cancer can be performed in selected patients, especially for those with localized (N0/N1) nodal disease. Induction chemotherapy should be performed.
