Objective To analyze the features of poststroke depression (PSD) between men and women after acute ischemic stroke in China. Methods A total of 1917 ischemic stroke patients were enrolled from the Prospective Cohort Study on Incidence and Outcome of Patients with Poststroke Depression in China. The incidence of PSD and the features were compared between male and female patients. The factors related with PSD of every gender were extracted with Logistic regression analysis. Results The incidence of PSD was higher in women than in men (32.9% vs. 26.6%, P<0.01). There was no difference in the stroke score between women and men (P>0.05). The score of Hamilton Depression Scale was higher in the women than in the men, and the features were similar. Logistic regression analysis indicated that the history of heart disease, history of mental disorders and stroke score related with PSD in women, while the age, history of mental disorders, smoking and stroke score in men. Conclusion The incidence and related factors of PSD 2 weeks after ischemic stroke are different between men and women.

OBJECTIVETo compare the clinical effects of close manipulative reduction combined with minimally invasive percutaneous plate fixation(MIPPO) and conventional open reduction and internal fixation (ORIF) for the treatment of proximal humerus fractures.

METHODSFrom April 2008 to March 2013, among the 75 patients with fractures of proximal humerus, 26 patients were male and 49 patients were female, ranging in age from 22 to 80 years; 18 patients had injuries caused by traffic accident and 57 patients had injuries caused by falling down. According to Neer classification, there were 49 cases of two-part fractures and 26 cases of three-part fractures. All the patients were divided into two groups: MIPPO group and ORIF group. There were 12 males and 21 females in the MIPPO group,including 22 cases of Neer two parts and 11 cases of Neer three parts, who were treated with close manipulative reduction combined with MIPPO. While the other 42 patients were in the ORIF group,including 16 males and 26 females. Among those patients,27 cases belonged to Neer two parts and 15 cases of Neer three parts, who were treated with ORIF. Length of the incision, blood loss, operating time, early postoperative pain(recorded by VAS), neck-shaft angle of proximal humerus and postoperative function of shoulder(recorded by Constant-Murley score, including pain, function, ROM and muscle length) were compared.

RESULTSThe mean lengths of incision were (6.74 +/- 0.38) cm in MIPPO group and (16.82 +/- 1.74) cm in ORIF group;blood losses were (110.15 +/- 29.49) ml in MIPPO group and (326.19 +/- 59.71) ml in ORIF group; operation times were (48.60 +/- 10.18) min in MIPPO group and (68.84-16.22) min in ORIF group. VAS of patients in MIPPO group on the 1st and 3rd days postoperatively were lower than those of patients in the ORIF group. The postoperative radiographs verified good position of all screws and satisfactory reduction of bone fracture reduction in both groups. All the patients were followed up,and the durig ranged from 8 to 24 months (mean 14.2 months). In the MIPPO group, there was no humeral head necrosis and all patients gained bone union; while in the ORIF group, 3 patients sustained nonunion and received reoperation for bone grafting, and 2 patients sustained humeral head necrosis. The mean Constant-Murley scores of shoulder were 88.94 +/- 2.57 in the MIPPO group and 86.00 +/- 3.36 in the ORIF group.

CONCLUSIONThe close manipulative reduction combined with MIPPO is a better choice for fixation of proximal humerus fractures, compared with conventional plate. This method possesses such advantages as a shorter incision, less disturbance of the blood supply and stable fixation of the fracture, allowing early exercise so that the function of shoulder recovers rapidly.

OBJECTIVETo investigate the prognostic factors for non-small cell lung cancer(NSCLC)in patients under 40 years of age.

METHODSThe clinicopathological data of 148 young patients with NSCLC were retrospectively analyzed. Kaplan-Meier and Cox regression analyses were used to analyze the relationship between prognostic factors and survival time.

RESULTSThe patients were followed-up for 6 - 148 months, and the follow-up rate was 100%. In the whole group, 122 patients died and 26 cases were surviving. The 1-, 3- and 5-year survival rates were 54.7%, 10.4% and 5.6%, respectively. The median survival time (MST) was 14.7 months. Kaplan-Meier analysis showed that Karnofsky performance status (KPS), clinical stage, treatment modality and serum CEA were related with prognosis (P < 0.05). Multivariate analysis indicated that KPS, clinical stage, treatment modality and serum CEA were independent prognostic factors (P < 0.05).

CONCLUSIONSKPS, CEA, clinical stage and treatment modalities are independent prognostic factors in young NSCLC patients.

BACKGROUNDThe extended spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) are the major pathogens causing pneumonia and have a significant impact on the clinical course. Limited data exist on molecular characterization of ESBL-producing E. coli and K. pneumoniae that cause pneumonia. The aim of this study was to investigate the comprehensive multilevel characteristics of E. coli and K. pneumoniae causing pneumonia in China for the first time.

METHODSE. coli (17) and K. pneumoniae (21) isolates responsible for pneumonia were isolated from 1270 specimens collected in a prospective multi-center study in eight teaching hospitals in China from June to December in 2007. The susceptibilities, ESBL confirmation, sequence typing, blaCTX-M and blaSHV genes, their genetic environment and plasmid Inc/rep types were determined.

RESULTSSixteen E. coli (94.1%) and eleven K. pneumoniae (52.4%) isolates were ESBL producers. About 77.8% and 66.7% of them were resistance to ciprofloxacin and levofloxacin, and 100% were susceptible to imipenem. The most prevalent ESBL gene was CTX-M-14, followed by SHV-2, CTX-M-15, CTX-M-3, CTX-M-65, SHV-12, SHV-26 and SHV-28. SHV-1 and SHV-11 were also detected and coexisted with blaCTX-Ms in five strains, and three strains contained only SHV-1. All CTX-M-14 were detected ISEcp1 upstream and nine were found IS903 downstream and the majority of them (64.3%) were carried by IncF plasmids. All blaSHV were flanked by recF and deoR, located on IncF, IncN, IncX and IncH plasmids. Two SHV-2, one SHV-1 and the only SHV-28 were further preceded by IS26. Genes lacY and lacZ were detected at further upstream of two blaSHV-1. The K. pneumoniae carrying SHV-28 was susceptible to β-lactams, and no mutations or deletions in gene or promoter sequences were identified to account for susceptibility. Multilocus sequence typing experiments showed the ESBL-producing strains were genetically diverse.

CONCLUSIONSThe rate of occurrence of blaESBL in E. coli and K. pneumoniae causing pneumonia was high, and blaCTX-M-14 was dominant and probably mobilized by ISEcp1 mainly on IncF plasmids. Importantly, unexpressed blaESBL genes may occur in susceptible isolates and hence may have clinical implications.

AIMTo evaluate the joint action of phoxim and fenvalerate on the reproductive function in male Sprague-Dawley rats.

METHODSThe 2 x 2 factorial analysis experiment was used in the study. The pesticides were orally given at daily doses of phoxim (Pho) 8.2 mg/kg, fenvalerate (Fen) 3.3 mg/kg and Pho 8.2+Fen 3.3 mg/kg (Pho:Fen = 5:2), 5 days a week for 60 days. Sperm motility was measured with computer-assisted sperm motility analysis (CASA) and daily sperm production estimated. Immunoenzymatic method and electron microscopy were used to evaluate the serum testosterone and the testicular morphology, respectively.

RESULTSThere were significant decreases in sperm motility parameters in the treated animals, including straight line velocity (VSL), beat cross frequency (BCF), linearity (LIN) and straightness (STR). After treated with Fen, significant decreases in VSL, LIN and STR were demonstrated. Significant decreases of daily sperm production were seen in animals treated with Pho and Pho+Fen in comparison with the controls. Serum testosterone levels were not significantly changed in the treated groups. Factorial ANOVA showed that no significant interactions were noted between Pho and Fen in sperm motility, sperm production and serum testosterone. Both the single and mixed pesticides caused various degrees of testicular lesions, involving vacuolation of endoplasmic reticulum and necrosis of Sertoli cells.

CONCLUSIONThe pesticides may cause sperm motility changes and testicular lesions in male rats. The action of Pho and Fen may be additive.
