Objective To evaluate the distribution and drug resistance of bacteria causing neonatal infectious pneumonia in Jiaxing,and to provide a therapy for clinical doctor to make a correct diagnosis,choose reasonable anti-biotics and avoid abuse of antibiotics.Methods Took expectoration from trachea in condition of asepsis to conduct culture and perform drug-sensitive test from 3025 cases.Results Totally 1 156 strains of aerobic bacteria were iso-lated.875 strains were gram negative bacilli(75.7%),269 strains were gram positive cocci(23.3%),and 12 strains were fungi(1.0%).Klebsiella pneumoiae,Escherichia coil,Acinetobacter baumanni,Enterobacter cloacae were com-mon in gram negative bacilli( respectively 178 cases,151 cases,87 cases,113 cases) .The proportion of the Staphylo-coccus aureus was the largest in gram positive cocci(245 cases) .The results showed that gram-negative bacilli were resistant to cefazolin, ampicillin, piperacillin and sensitive to meropenem, imipenem, piperacillin-tazuobatanna and cefoperazone-sulbactam.The drug resistance was severe of ESBL-positive.Staphylococcus aureus was resistant to penicillin, ampicillin, erythrocin, clindamycin and sensitive to linezolid, vancomycin, nitrofurantoin.Conclusion Gram-negative bacilli are the main bacteria in neonatals with infectious pneumonia.The drug resistance is severe.It is important to make a standard management and isolation.

One hundred and seventy-two strains of endophytic fungi were isolated from Taxus mairei,Cephalotaxus fortunei and Torreya grandis cv.merrillia.The result of the antifungal assay shows that ninety strains of the fungi have antagonism against one or more botanical pathogenic fungi,such as Neurospora sp.,Trichoderma sp.,Fusarium sp.etc.The percentage of antifungal strains to tested strains are as follows:40% Cephalotaxus fortunei,54.2% Taxus mairei,57.1% Torreya grandis cv.merrillia.Thirty-five strains have high antifungal activities,and their inhibition zone diameter is at least 15mm.The active endophytic fungi were identified as 18 genera,most of which belong to Paecilomyces and Fusarium etc.

It is now well established that inflammation plays an important role in the development of numerous chronic metabolic diseases including insulin resistance (IR) and type 2 diabetes (T2DM). Skeletal muscle is responsible for 75% of total insulin-dependent glucose uptake; consequently, skeletal muscle IR is considered to be the primary defect of systemic IR development. Our pre- vious study has shown that rutaecarpine (Rut) can benefit blood lipid profile, mitigate inflammation, and improve kidney, liver, pan- creas pathology status of T2DM rats. However, the effects of Rut on inflammatory cytokines in the development of IR-skeletal muscle cells have not been studied. Thus, our objective was to investigate effects of Rut on inflammatory cytokines interleukiri (IL)-1, IL-6 and tumor necrosis factor (TNF)-α in insulin resistant primary skeletal muscle cells (IR-PSMC). Primary cultures of skeletal muscle cells were prepared from 5 neonate SD rats, and the primary rat skeletal muscle cells were identified by cell morphology, effect of ru- taecarpine on cell proliferation by MTT assay. IR-PSMC cells were induced by palmitic acid (PA), the glucose concentration was measured by glucose oxidase and peroxidase (GOD-POD) method. The effects of Rut on inflammatory cytokines IL-1, IL-6 and TNF-α in IR-PSMC cells were tested by enzyme-linked immunosorbent assay (ELISA) kit. The results show that the primary skeletal muscle cells from neonatal rat cultured for 2-4 days, parallel alignment regularly, and cultured for 7 days, cells fused and myotube formed. It was shown that Rut in concentration 0-180. 0 μmol x L(-1) possessed no cytotoxic effect towards cultured primary skeletal muscle cells. However, after 24 h exposure to 0.6 mmol x L(-1) PA, primary skeletal muscle cells were able to induce a state of insulin resistance. The results obtained indicated significant decrease (P < 0.05 to P < 0.001) IL-1, IL-6 and TNF-α production by cultured IR-PSMC cells when incubating 24 hours with Rut, beginning from 20 to 180.0 μmol x L(-1). IL-1, IL-6 and TNF-α in the Rut treated groups were dose-dependently decreased compared with that in the IR-PSMC control group. Our results demonstrated that the Rut promoted glucose consumption and improved insulin resistance possibly through suppression of inflammatory cytokines in the IR-PSMC cells.

Objective To summarize the ultrasonic characteristics of urinary calculus in infants who had history of feeding melamine contaminated milk powder.Methods A total of 163 children[aged(19.4?10.9)months] with urolithiasis,who had feeding melamine contaminated milk powder,were retrospectively analyzed using ultrasonography.Twenty children [aged(16.7?9.9)months] with urolit-hiasis,who had no feeding history of melamine contaminated milk powder,were chosen as controls.Ultrasonic characteristics were compared between the 2 groups.Results For melamine calculus cases,sporadic spot or hyperechic mass with different size and shape in the collecting system,partly without acoustic shadow,was found in 65 cases;dense echo and luminous belt with obscured acoustic shadow under a band without echo was found in 48 ureteral calculus cases;irregular strong echo mass or small spot with thick acoustic shadows without side lobe artifact in the dark liquid areas was found in 8 cases with bladder calculus.There was significant difference in morphology of the calculus(P0.05).Conclusions The unique ultrasonic characteristics in infants with melamine calculus had become a very useful tool to diagnose the pediatric urinary melamine calculus.J Appl Clin Pediatr,2009,24(1):67-69

OBJECTIVE: To investigate the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs. METHODS: Sixty-two rabbits were randomly divided into drowning group (n = 30), postmortem immersion group (n = 30) and land death group (n=2), and the diatoms in each lung lobe were analyzed quantitatively and qualitatively by microwave digestion and scanning electron microscopy. RESULTS: In the drowning group, the diatoms were detected in each lung lobe with Cyclotella and Melosira in the majority. In the postmortem immersion group, Cyclotella was in the majority. And the diatoms weren't detected in some lung lobes in postmortem immersion. There were significant differences in the detection rates of upper lobe of left lung, middle lobe and cardiac lobe of right lung in two groups (P < 0.05). CONCLUSION Based on the microwave digestion and scanning electron microscopy, the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs can be analyzed and used as references for testing theory.

The inhibitory ratio (1%) of artificial musk on cyclooxygenase-2 (COX-2) was determined by enzyme immunoassay (EIA). The dose-effect relationship between concentrations of artificial musk and 1% was established. It was found that artificial musk had obvious inhibitory action on COX-2. The concentration for 50% of maximum inhibitory effect (IC50) was about 2.26 mg x mL(-1). There was a good relationship between the logarithm concentrations of artificial musk and 1% when the concentrations of artificial musk ranged from 0.31-20.0 mg x mL(-1). The results indicated that this EIA method could be applied to evaluate the anti-inflammatory activity of artificial musk quickly, conveniently, sensitively and exactly. This paper provided a novel method and foundational research for the bioassay of artificial musk.

ObjectiveTo analyze therapeutic effects of conservative treatment and the causes of malunion of intertrochanteric fracture in elderly patients, and try to find the way to deal with the problems. MethodsFifteen cases aged 75 to 101 years with intertroehanterie fracture treated conservatively were included.Their average age was 88.8 years.All fractures were classified according to Evens-Jensen.Because of the medical complication or other reasons, they were conservatively treated by methods of traction, wearing shoes et al. X-ray examination was taken at regular time and their final functions were assessed. ResultsTwo cases were died 1-3 months after admission, and the fractures were only partially healed. The remaining thirteen cases got complete healing. Among the fifteen cases, the deformity did not happen in 4 cases of IA without fixation and 1 case of IIB with bone traction. All others got the deformity of varus, shorting and external rotation in different degree, which interfered the lower extremity motor function. ConclusionsThe fracture position not kept and fixed satisfactorily during treatment would lead to more joint deformity and deteriorated hip joint function for the displaced intertroehanterie fractures in elderly patients.

OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.

METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.

RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.

CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.
