To investigate the effect of atorvastatin on lipid metabolism in type 2 elder diabetes patients with hyperlipidemia, 26 patients with type 2 elder diabetes complicated with hyperlipidemia were treated with atorvastatin (10 mg/d) for 8 weeks. The serum triglyceride (TG), high density protein cholesterol (HDL-C) and low density protein cholesterol (LDL-C) were measured before and after the treatment. Meanwhile, the non-denaturing polyacrylamide gradient gel electrophoresis was used for detection of small-sized LDL(SLDL). Our results showed that TG dropped from 4.88 +/- 0.72 mmol/L to 2.65 +/- 0.32 mmol/L; HDL-C was increased from 0.85 +/- 0.31 mmol/L to 1.28 +/- 0.29 mmol/L; LDL-C was declined from 3.71 +/- 2.98 mmol/L to 2.10 +/- 1.22 mmol/L, sLDL-A was increased from (42.49 +/- 8.1)% to (53.27 +/- 7.5)%; LDL-B was decreased from (57.91 +/- 8.1)% to (46.73 +/- 7.5% ) (P<0.05). The level of blood glucose was not changed at the end of 8th week. It is concluded that atorvastatin has satisfactory lipid-regulating effects on type 2 elder diabetes patients with hyperlipidemia.

To explore the compatibility characteristics of herbs used for nourishing yin in formulas of kidney-yang tonifica-tion.It is noticed that the appearance frequency of such herbs for yin nourishment as Radix Rehmanniae Praeparata,Rhizoma Dioscoreae,Fructus Corni and Fructus Lycii comes out on the top.Either the dosage ratio or the number of herbs of yin nour-ishment in the modern formulas for tonifying kidney yang is evidently increased than that of the ancient formulas,with the ap-plication scope being expanded.Hence,it is believed that compatibility of herbs for nourishing yin in formulas of kidney-yang tonification has become a major compatibility form in the clinical practice.When deficiency of kidney essence is obvious,the dosage of herbs for nourishing yin should be increased.While when the internal generation of deficient cold takes a dominant place,the dosage should be decreased,which is able to provide a reference for the reasonable application of formulas for kidney-yang tonification in clinical practice.

Objective To evaluate therapeutic effects of wedge resection on male paraurethral duct dilatation following gonococcal paraurethral duct infection. Methods With the aid of high-frequency ultrasound images, 11 male patients with paraurethral duct dilatation following gonococcal paraurethral duct infection were treated with wedge resection. The data were collected, including the surgical duration, amount of bleeding during the surgery, period of wound healing and complications. If the ostium beside the external urethral orifice disappeared within 4 weeks after the surgery, there was no discharge from the ostium with pressure, and no tubular echoic area was observed by high-frequency ultrasound imaging, the patient was considered to be recovered. If none of the above three conditions could be met, the surgical treatment was considered to be ineffective. Results The average surgical duration was 19.19 ± 2.71 minutes(range, 14-23 minutes), the average amount of bleeding during the surgery was 11.09 ± 2.07 ml (range, 8-14 ml), and the average period of wound healing was 14.91 ± 1.45 days(range, 13-17 days). Of the 11 patients, 10 were cured, and 1 showed no response. No complications were observed in any of the 11 patients, and no defects formed in the glans penis. Conclusion Wedge resection is a kind of effective therapy for paraurethral duct dilatation following gonococcal paraurethral duct infection in males.

Objective To investigate the morphologic characteristics of gonococcal inflammation of paraurethral glands in males. Methods Eleven male patients with gonococcal inflammation of paraurethral glands were examined by both real-time ultrasound imaging (Siemens Acuson X300) and 3.0 T magnetic resonance imaging (MRI, Philips Achieva). Results High-frequency ultrasound imaging revealed tubular echoic areas with well-defined borders and smooth margins in all the patients. The inside of these tubular areas was weak-echoic. These tubular echoic areas were blind in one end, but open in the other end, and ran in parallel with the urethra. The mean lumen diameter was 1.1 ± 0.2 mm (range, 0.7 - 1.3 mm) , and the mean lumen length was 8.4 ± 0.6 mm (range, 7.0 - 12.0 mm). Anechoic liquid-filled areas were seen in the tubular echoic areas in two patients. Paraurethral ducts were not detected by 3.0 T MRI in these patients. Conclusions High-frequency ultrasound imaging can clearly show the morphologic characteristics of gonococcal inflammation of paraurethral glands in males, and provide valuable ultrasound images for surgery.

Objective To investigate influence factors on neonatal necrotizing enterocolitis (NEC) and find a preventive way against the said disorder. Methods A retrospective study was conducted of 63 cases NEC (observation group) and 70 cases non-NEC (control group) admitted to the neonatal intensive care units (NICU) of two hospitals from January 2010 to May 2014. The cases were grouped in 29 factors. The individual factors of 28 out of the 29 factors were analy-sised with SAS 9.1 statistical software, and the screened important factors were investigated by logistic regression. Re-sults The ratios of 4 factors, application of prenatal corticosteroids, breast feeding prior to the ailment, oral probiotics and hyperbilirubinemia in the observation group were lower than those in the control group, while the ratios of 14 factors were higher than those in the control group, premature rupture of membrane, asphyxia, respiratory distress syndrome, respiratory failure, umbilical venous catheters, oxygen uptake, sepsis, septic shock, disseminated intravascular coagula-tion (DIC), congenital heart disease, scleredema, hyponatremia, hypocalcaemia and transfusion. The differences of fac-tors mentioned were of statistic significance (P<0.05), while the differences of other factors were not statistically signifi-cant between the two groups (P>0.05). Logistic regression analysis indicated that breast feeding, oral probiotics and hy-perbilirubinemia were protective factors against NEC; while sepsis, congenital heart disease and transfusion were major factors that lead to NEC. Conclusion NEC resulted from a combination of multiple factors, with sepsis, congenital heart disease and transfusion as the leading ones. Breast feeding, oral probiotics, and non-excessive curing against hyper-bilirubinemia will help reduce the incidence of NEC.

OBJECTIVETo investigate the occupational stressors and modifiers of pediatricians and nurses in order to find the measurements for control of the job stress.

METHODS427 pediatricians and nurses working in five hospitals of a city served as subjects. Of them, the staff in section of pharmacy and toll offices in each hospital mentioned above served as control group. The General Job Stress Questionnaire was used to investigate the job stress by self-assessment.

RESULTSThe scores of job demand, job risk, drug using, daily job stress, positive feelings, patient A behavior, physical environment and feeling balance in pediatricians and nurses were higher than those of control group, but the scores of job-person conflict, environmental control, technology utility, mental health, responsibility on things were lower than those of control group (P<0.05). The points of job future, job locus of control, self-esteem, job satisfaction, job load variance, depression in nurses were higher than those of pediatricians, and non-work activities, job risk and daily life stress were lower than those of doctors (P<0.05). The main affecting factors on job strain of pediatric staff included job monotony, higher job demand, more non-work job, lower job control, more job risk, job future ambiguous, poorer social support, lower job locus control and lower self-esteem.

CONCLUSIONThe stress degree of pediatric staff is higher than that of controls. The pediatricians have more job stress than that of nurses. The main stressors of pediatric staff are job monotony, higher job demand, more non-worker activity, lower job control, higher job risk and ambiguous job future. The main modifiers are good social support, external job locus of control and higher self-esteem.

BACKGROUNDAn inflammatory response leading to organ dysfunction and failure continues to be a major problem after injury in many clinical conditions such as sepsis, severe burns, and trauma. It is increasingly recognized that atrial natriuretic peptide (ANP) possesses a broad range of biological activities, including effects on endothelial function and inflammation. A recent study has revealed that ANP exerts anti-inflammatory effects. In this study we tested the effects of human ANP (hANP) on lung injury in a model of oleic acid (OA)-induced acute lung injury (ALI) in rats.

METHODSRats were randomly assigned to three groups (n = 6 in each group). Rats in the control group received a 0.9% solution of NaCl (1 ml × kg(-1) × h(-1)) by continuous intravenous infusion, after 30 minutes a 0.9% solution of NaCl (1 ml/kg) was injected intravenously, and then the 0.9% NaCl infusion was restarted. Rats in the ALI group received a 0.9% NaCl solution (1 ml × kg(-1) × h(-1)) intravenous infusion, after 30 minutes OA was injected intravenously (0.1 ml/kg), and then the 0.9% NaCl infusion was restarted. Rats in the hANP-treated ALI group received a hANP (0.1 µg × kg(-1) × min(-1)) infusion, after 30 minutes OA was injected intravenously (0.1 ml/kg), and then the hANP infusion was restarted. The anti-inflammation effects of hANP were evaluated by histological examination and determination of serum cytokine levels.

RESULTSSerum interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor (TNF) α were increased in the ALI group at six hours. The levels of all factors were significantly lower in the hANP treated rats (P < 0.005). Similarly, levels of IL-1β, IL-6, IL-10 and TNF-α were higher in the lung tissue in the ALI group at six hours. hANP treatment significantly reduced the levels of these factors in the lungs (P < 0.005). Histological examination revealed marked reduction in interstitial congestion, edema, and inflammation.

CONCLUSIONhANP can attenuate inflammation in an OA-induced lung injury in rat model.
