CON-CLUSIONS:The method is simple and accurate,and can be used for the content determination of menthanol in Qinagli pipa syrup.

Objective To investigate the influence of balanced anesthesia(BA) and total intravenous anesthesia(TIVA) on the hemodynamics and respiratory function in elderly patients undergoing laparoscopic hysterectomy.Methods Fifty elderly patients undergoing elective hysterectomy.Their mean age was 62.7?1.8 years.ASA Ⅰ-Ⅱ class.They were randomly divided into two groups: balanced anesthesia group and total intra-venous anesthesia group.The perioperative data of hemodynamics,respiratory system and arterial blood gas were recorded,and the compliance of respiratory system was calculated.Results The MAP at 10 minutes after pneumoperitoneum(PP) was greatly higher than that of the pre-induction period in BA group(P

Objective To explore the effect of lidocaine, the sodium channel blocker, on electrical physiological changes in the circumstances of hypoxia. Methods The effects of different doses of lidocaine (10~ -5 mol/L, 10~ -4 mol/L and 5?10~ -4 mol/L) on the changes in voltage-dependent sodium currents in hippocampal neurons of the rat induced by 10~ -5 mol/L DNP (2,4-dinitrophenol) were recorded by whole-cell configuration of the patch clamp. Results DNP could increase the spike amplitude of sodium currents significantly. With the application of 10~ -5 mol/L and 10~ -4 mol/L lidocaine in advance, the spike values of each group were not significantly different from that of the contral after the administration of DNP, but the spike values after 5?10~ -4 mol/L lidocaine were lower than that of the control after the administration of DNP. Conclusion With the use of DNP, lidocaine can achieve the effect of brain protection through inhibiting the voltage-dependent sodium channel.

Objective To investigate the influence of balanced anesthesia(BA)versus total intravenous anesthesia(TIVA)on the hemodynamics and respiratory function of patients undergoing laparoscopic hysterectomy.Methods Two groups of patients undergoing elected laparoscopic hysterectomy received balanced anesthesia(BA group,20 cases)or total intravenous anesthesia(TIVA group,20 cases)respectively.Data of hemodynamics and respiratory system were recorded and the compliance of respiratory system was calculated.Results The MAP at 10 minutes after pneumoperitoneum(PP)was elevated significantly than that before-induction in BA group(P

Objective To investigate the predisposing factors and fungal characteristics of nosocomial fungal infection (NFI) in patients with chronic kidney disease (CKD). Methods The fungal characteristics and laboratory indices were analyzed in patients with and without NFI secondary to CKD. Results The most common infection site of NFI in 65 cases patients with CKD was urinary tract (25 man-times, 38.46%), and the second common site was digestive tract (20 man-times, 30.77%). The most common pathogenic fungus was Candida albicans (68.49%), followed by Candida tropicalis (17.81%). The sensitivity of Candida albicans to fluconazol was 90%. The predisposing factors included prolonged length of stay, anaemia, malnutrition, hypogammaglobulinemia, mass proteinuria, renal insufficiency, and the use of large dose of broad spectrum antibiotics, prednisone and cytoxan. Conclusion CKD may predispose to NFI, and the most common fungus is Candida albicans,so the predisposing factors should be controlled so as to prevent NFI among patients with CKD.

OBJECTIVE:To optimize the extraction process of paishi granule.METHODS:The extraction process of paishi granule was optimized by L 9 (3 4 )orthogonal test with total flavonoids as index,and with duration of decoction,times of de?coction,the amount of water added and the amount of alcohol used for extraction as factors of investigation.RESULTS:The optimum extraction condition was the following,the amount of water added to which was12times that of the medical material,and it was decocted120min for3times,which then was dried and crushed,then60%alcohol,which was40times that of the amount of medicinal material,was extracted by refluxing for3times with30min each time,filtered while hot,and the alcohol was recovered.The yield of extractum and the content of the total flavonoids were fairly high,and there was a good repro?ducibility.CONCLUSION:The optimized process is stable and feasible.

Gestational diabetes mellitus is detrimental to the health of both the mother and the fetus,and therefore greater attention is being paid to the earlier diagnosis and treatment of the condition.This article offers an overview of the research progress in the predictive factors of gestational diabetes mellitus.

The infant with macrosomia has been the focus of attention and controversy for some time, and fetal macrosomia affects neonatal and maternal morbidity and mortality. This review summarized the etiological factors of fetal macrosomia.

Thioredoxin-interacting protein (TXNIP), also known as vitamin D3-up-regulated protein (VDUP1), is an endogenous inhibitor of thioredoxin (Trx), which regulates the cellular reduction-oxidation (redox) state. TXNIP regulates cellular survival, apoptosis and inflammation induced by glucotoxicity, heat shock and mechanical pressure. The above functions of TXNIP are regulated by carbohydrate response element binding protein (ChREBP) and AMP-dependent protein kinase (AMPK). In recent years, numerous studies showed that TXNIP is involved in diabetes and diabetic complications. On the one hand, TXNIP functions in diabetes by increasing insulin resistance and hepatic gluconeogenesis. TXNIP expression is induced by high glucose, which is implicated in pancreatic beta cell glucotoxicity and endothelial cells dysfunction. TXNIP may contribute to the development and progression of diabetes and its vascular complications. TXNIP may be a new target for diabetes and its vascular complications therapy.

Objective To describe the lived experience of mothers of children with hydrocephalus. Methods A semi-structured interview was conducted with 14 mothers of children with hydrocephalus. Data were analyzed based on Colaizzi phenomenotogical research method. Results Through the analysis, sorting and refining the theme, the mother's care experience could be divided into three themes: psychological emotional, stress response, social support requirements. Conclusions Nursing staff should have a thorough understanding of the experience to provide medical care and emotional support, improve the ability of the parents care,which could help caregiver adapt to their roles, maintain and promote the health of children patients and their families .
