Objective To identify the genotypes of ESBLs-producing Klebsiella pneumoniae isolates from the First Affiliated Hospital,Shantou University Medical College.Methods The MICs of 10 antibiotics were determined by agar-dilution against the clinical isolates of ESBLs-producing K.pneumoniae.PCR were performed with specific primers for blaTEM,blaSHV, blaCTX-M and blaOXA respectively.PCR products were cloned and sequenced.Results The results of PCR showed that a- mong the 83 strains of ESBLs-producing K.pneumoniae,75 were positive for blaTEM,41 positive for blaSHV,25 poitive for blaCTX-M,9 positive for hlaOXA.Three genotypes were found in 13 strains(15.7%),2 genotypes in 59 strains (71.1%) and single genotype in only 11 strains(13.2%).The genes of CTX-M-3,TEM-1 and SHV were found co-existent in 9 strains. The strains carrying 2 or 3 ESBL genes were more resistant to antibiotics than those carrying only 1 ESBL gene.Conclusions The genotypes of ESBLs-producing Klebsiella pneumoniae in this hospital are blaTEM,blaSHV,blaCTX-M and blaOXA. Most strains carry 2 or 3 ESBL genes.

Introduction:Neonatal tetanus is a major cause of neonatal mortality in many developing countries and remains a major public health problem. This study aimed to determine risk factors associated with neonatal tetanus in Wenzhou, China.Methodology:Medical records of neonatal tetanus cases from 17 hospitals over a 13-year period (2000–2012) were reviewed for potential risk factors. Controls were selected from neonates with diseases other than tetanus who were admitted to the same facility during the same period. The potential risk factors of the neonatal tetanus group were compared with the control group using univariate analysis and an unconditional logistic regression model.Results:A total of 246 neonates with tetanus and 257 controls were included in this study. Univariate analysis showed that having untrained birth attendants, home delivery, an unsterile method of delivery and being a migrant to Wenzhou were significantly different between the two groups (

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.
METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.
RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].
CONCLUSIONDOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

OBJECTIVETo report the first case of transumbilical laparoendoscopic single-site surgery-assisted vaginal hysterectomy in South China, and discuss its feasibility and safety.
METHODSA 42-year-old woman with multiple myoma of the uterus underwent laparoendoscopic single-site surgery-assisted vaginal hysterectomy performed using a single multiple-channel port inserted through a solitary 2 cm upper umbilicus incision.
RESULTSThe total operative time was 3 h, and duration of the laparoendoscopic procedure was 2 h. The surgery was completed uneventfully without an additional port incision or transfer to open surgery. The intraoperative blood loss was 100 ml. Bowel peristalsis was recovered 3 days after the operation. The vaginal stump and abdominal incision healed smoothly without occurrence of vaginal bleeding.
CONCLUSIONWith the development of surgical instruments and improvement of the surgeons' skills, laparoendoscopic single-site surgery, due to its invasiveness, can be a promising approach to the management of gynecological disease including gynecological malignant tumors.

OBJECTIVE:
To study the relationship between the DNA content in follicular epithelial cells of the human thyroid and postmortem interval (PMI).
METHODS:
Changes of the DNA content in thyroid follicular epithelial cells at different PMI were determined by Methyl Green-Pyronin (MGP) stain combined with an image analysis technique.
RESULTS:
The average DNA content in the thyroid follicular epithelial continued to decrease with increased PMI. The coefficient of determination for DNA content with average gray, aimed area, aimed area ratio and positive index in follicular epithelial cells were 0.960, 0.987, 0.988 and 0.990, respectively.
CONCLUSION
There is an apparent correlation between the average DNA content of follicular epithelial cells and the PMI. MGP stain combined with an image analysis technique seems to be a useful means to study the degradation of DNA in thyroid follicular epithelial cells.

BACKGROUNDIn both the seventh edition of the International Union Against Cancer (UICC) staging system for gastric cancer and the 14th edition of the Japanese Gastric Cancer Association (JGCA) system, T(4a) is defined as "Tumor perforates serosa (visceral peritoneum) without invasion of adjacent structures." The aim of this study was to investigate the differences in prognosis between patients with serosa-penetrating and serosa-invading T(4a)N(0)M(0) gastric carcinomas.
METHODSData were collected from 221 patients with T(4a)N(0)M(0) gastric carcinoma who underwent D2 resection at our cancer center between January 1990 and December 2008. The cohort included 42 patients with serosa-penetrating tumors and 179 patients with serosa-invading tumors. The average follow-up time was 85.5 months. Spearman's rank correlation, Kaplan-Meier plots, and Cox proportional hazards regression models were used to analyze the data.
RESULTSThe 5-year survival rate of patients with serosa-penetrating and serosa-invading gastric cancers were 31% and 62% respectively (P < 0.05). The relapse rates after D2 radical surgery were 16.2% in patients with serosa-invading gastric cancer versus 59.5% in those with serosa-penetrating tumors (P < 0.05). Peritoneal dissemination and distant organ/lymph node metastatic rates were 76.0% and 24.0% respectively in patients with penetrating tumors, versus 44.8% and 55.2% respectively in patients with invading tumors (P < 0.05). Multivariate analysis showed that penetration of the serosa was an independent prognostic indicator of overall survival.
CONCLUSIONSOur findings provide a basis for the concept that serosa-penetrating T(4a)N(0)M(0) gastric carcinoma represents a more aggressive cancer than serosa-invading T(4a)N(0)M(0) gastric carcinoma. Serosa penetration is an independent factor for poor prognosis of patients with gastric carcinoma.

A new species of Alternaria causing leaf spots on the rubber tree (Hevea brasiliensis) in Yunnan, China, was isolated, examined, and illustrated. Morphologically, it belongs to the section Porri of Alternaria, which produces relatively large conidia and a simple or branched, filamentous long beak. It is, however, characterized by conidiophores gradually enlarging near the apex into a clavate conidiogenous cell and long ellipsoid to obclavate, smooth-walled conidia with a long filamentous beak. Molecular phylogenetic analyses based on ITS rDNA, GAPDH, and TEF1-alpha sequences demonstrate that the phytopathogen falls in the clade of the section Porri, being most closely related to A. sidae, A. sennae, A. deseriticola, A. cyamopsidis, A. rostellata, A. nitrimali, A. crassa, and A. thunbergiae.
