OBJECTIVETo investigate the feasibility and therapeutic results of multiple organ resection in patients with tumor of the body and tail of pancreas.

METHODSThe clinical and pathological data were analysed in 16 consecutive patients with neoplasm of the body and tail of pancreas from 1999 to 2004 retrospectively.

RESULTSMultiple organ resection was performed in 6 cases of primary pancreatic adenocarcinoma of the body and tail (3 cases of pancreatic cancer, 2 cases of malignant glucagonoma, and 1 case of well-differentiated pancreatic stromal sarcoma) and 10 cases of extrapancreatic malignancy (4 cases of gastric cancer, 2 cases of gastric leiomyosarcoma, 1 case of duodenal cancer, and 3 cases of colon cancer of hepatic flexure). Distal pancreatectomy with splenectomy was performed in all cases. In addition, 10 patients received splenic flexure colectomy, 6 patients received distal gastrectomy, 3 patients received left nephrectomy, left colectomy, total gastrectomy, liver lobe resection, left adrenalectomy, and local diaphragma resection, and 2 patients received transverse colectomy, subtotal colectomy, proximal proctectomy, proximal gastrectomy, and duodenectomy. No perioperative death and severe complications were observed. Patients with primary pancreatic cancer or pancreatic stromal sarcoma died within 1 year. Two patients with malignant glucagonoma died 51 and 39 months later. The 3-year survival rate was 70% in 10 patients with extrapancreatic malignancy, among which 2 patients with enteric cancer have survived 37 and 48 months.

CONCLUSIONRadical combined multiple organ resection may be performed actively in appropriately selected patients.

OBJECTIVETo analyse the mutation of ADAR gene in a pedigree with dyschromatosis symmetrical hereditaria (DSH).

METHODSA pedigree of DSH was investigated. Mutation scanning was carried out by PCR and direct sequencing. ADAR gene of 50 normal people was also sequenced as control. Through CBMdisc and PubMed, the mutations of ADAR gene were summarized.

RESULTSA novel mutation of c.2447G > A was found in all patients with DSH, but was not found in normal individuals in this DSH family and 50 unrelated controls. There were 64 mutations in ADAR gene.

CONCLUSIONA deletion mutation (c.2447G > A) in the ADAR gene has been detected in this DSH family, which is probably one of the molecular bases of the pathogenesis of the disease. Author have summarized a total of 64 mutations in the ADAR gene by previous reports and speculate that the mutation hotspots of ADAR gene might be located in the tRNA-specific and double-stranded RNA adenosine deaminase (ADEAMc) domain.

Objective To investigate the geographic distribution panem of patients with anorectal atresia/stenosis in China.in order to provide clue for research on its etiology.Methods Data were collected from Chinese Birth Defects Monitoring Network(CBDMN),which was a hospital-based congenital malformations registry system.From 2001 to 2005,all fetuses with more than 28 weeks of gestation and neonates up to 7 days of age,were monitored.Two-dimensional graphic cluster method was used to divide monitoring stations into difierent classes with the incidence rates of anorectal atresia/stenosis.Results The overall incidence of anorectal atresia/stenosis was 3.17 per 10000 during 2001 to 2005.The incidence was higher in Eastern than that in Mid or Western paas of China and tbe difierence was statistically significant(z=2.50,3.69;P=0.012,＜0.001).The monitoring stations were grouped into 6 classes.Class I was with Helongjiang,Jilin and Liaoling;Class Ⅱ was with Fujian,Guangdong,Hainan,Guangxi,and South Hunan and Jiangxi;ClassⅢwas with Beijing,Tianjin,Hebei,Shandong,and Noah Jiangsu and Anhui;Class Ⅳ was with Zhejiang,Shanghai,South Anhui and Jiangsu,Noah Hunan and Jiangxi,Hubei,Henan,Shanxi and Inner Mongolia,Class V was with Ningxia,Gansu and Qinghai;and Class Ⅳ was with Shaanxi,Sichuan,Chongqing,Yunnan,Guizhou.Xinjiang and Tibet.Conclusion Our findings discovered the geographic distribution patterns of patients with anorectal atresia/stenosis in China.It is important to further analyze the relevant environmental factors attached to it so a beRer regional monitoring system for anorectal atresia/stenosis can be operated.

OBJECTIVE: To explore the applicability of magnetic resonance diffusion tensor imaging (DTI) for diagnosis of pyramidal tract damage in rats. METHODS: Marmarou's model was set up, followed by DTI scanning at 3, 12, 24 and 72 h post trauma to acquire the dispersion parameter of bilateral pyramidal tracts. Moreover, axonal varicosities per square millimeter and the percentage of positive area of axons demonstrated by beta-amyloid precursor protein (beta-APP) immunostaining were obtained, as well as the mean density and sum density of neurofilament (NF) 68 immunostaining. RESULTS: Axial diffusivity (AD), fraction anisotropy (FA) and relative anisotropy (RA) in the pyramidal tract were significantly and continuously reduced and reached to the bottom at 72h post trauma (P < 0.05) in accord with the gradient of axonal damage verified by beta-APP and NF68 immunostaining. Furthermore, the changes of AD, FA and RA showed a significant negative correlation with the beta-APP immunohistochemical results. CONCLUSION DTI has important value for early diagnosis in pyramidal tract damage.

OBJECTIVETo explore the rate of compliance, influencing factors and the safety of patients with onychomycosis under treatment of oral antifungal agents.

METHODSAccording to the scoring clinical index of onychomycosis (SCIO), 330 patients with onychomycosis, their target nail's integral of the SCIO were calculated and randomly divided into three groups under the baseline of the SCIO integral range. Patients were treated with intermittent pulse itraconazole (A group), continuous terbinafine (B group) and intermittent terbinafine (C group) respectively. Self-administered questionnaire was applied in the survey on every onychomycosis patient.

RESULTSThe average rate of compliance was 55.15%. The cure rate for those compliance with doctors' order was 89.01%, while it was only 30.41% for those noncompliant patients The overall non-compliant rate was 44.85%. Among the noncompliant ones, 29.73% were worried about the side effects of medicine, 22.30% thought that they had already been cured, 15.54% was due to economic reasons and 12.16% could not bear the side effects of medicine. It was found that the compliant rates were significantly correlated to ageing, position of the target nails, the integral of the SCIO and the therapy scheme (P < 0.05), while no significant correlations were seen between male and female, culture degree and course (P > 0.1). The frequency of adverse incident of A, B, C groups were 22.73%, 21.43%, 23.15% respectively, but without statistical significance (P > 0.1). Majority of the adverse incidents happened during the first month of therapy but were mild and reversible.

CONCLUSIONOur results showed that the overall compliance was low which exerted a significant influence on the curative effect of onychomycosis patients. Factors as ageing, position of the target nail, integral of the SCIO and the therapy scheme had an influence on the compliant rate. When treating onychomycosis with oral itraconazole, the results seemed to be just as safe as when using terbinafine.

To explore the mode of"one-day outpatient"based continuous management and examine its feasibility and preliminary effects for improving menopausal syndrome and mood among menopausal women.Clinical intervention study was conducted in Obstetrics and Gynecology Center of the Third Affiliated Hospital of Chongqing Medical University from May 2020 to May 2021.The continuous management mode of "one-day outpatient service" for menopause was constructed in terms of multidisciplinary resources, including offline "one-day outpatient" health education, online 7-week group continuous intervention on "healthy lifestyle" and offline half-day focus group interview. Pre-and post-scores of the modified Kupperman scale and the positive/negative emotional scale (PANAS) were measured to compare the status of menopausal syndrome and emotional experience of Seventy-eight female participants (40-60 years old), meanwhile, before and after comparison of the blood lipid and body composition indexes of participants were also performed. Paired t test or Wilcoxon signed rank test were used.Results show that the pre-and post Kupperman scores were 14.65±8.51 vs 10.26±5.83 ( t=-5.59, P<0.01), and the positive emotional scores (pre- 28.53±5.85 vs post- 30.13±6.30) were improved ( t=2.59, P=0.012) and negative emotional scores [pre- 20.5(10) vs post- 17.0(7)] were decreased ( Z=-5.09, P<0.01). The triglyceride level of participants declined from (1.27±0.54) mmol/L to (1.09±0.38) mmol/L ( t=-2.45, P<0.05). In addition, the body mass index(pre- 22.52±2.34 vs post- 22.06±2.22), percentage of body fat (pre- 31.72±6.22 vs post- 30.91±6.52)and Visceral fat area(pre- 83.96±30.26 vs post- 79.66±29.71) were all improved ( t=-3.58, t=-2.57, t=-2.59, P<0.05). Therefore,the mode of"one-day outpatient"based continuous management can effectively improve menopausal syndrome and adverse mood, reduce patients′ blood lipid, improve the body composition, and maybe contribute to the prevention of long-term chronic diseases.
