Insulin resistance induces multiple metabolic disorders and are the common risk factors of diabetes mellitus and cardiovascular diseases.Since the causes are complex,the medical management should be integrated to treat insulin resistance.Lifestyle change is the first choice,and the appropriate agents can be selected if needed.

Objective To establish a method for simultaneous determination of 12 kinds of organophosphorus pesticides in water. Methods Organophosphorus pesticides in the water were extracted by liquid-liquid extraction, then analyzed with DB-1701 capillary column. In the same time, they were determined with GC by controlling the temperature and the speed of nitrogen. Retention time of the peaks was used for qualitative analysis, while external standard method was used for the quantitative analysis. Results The linear ranges of organophosphorus pesticides were 0.2～50.0 ?g/L, r≥0.999 1. The lowest detection limit was 0.009～0.04 ?g/L, the rate of recovery were 78.4%～93.9% and RSDs were 3.4%～7.5%. Conclusion This method is simple, rapid, sensitive and can efficiently separate and determine 12 kinds of organophosphorus pesticides in the water with 32.5 minutes of operation only.

Objective To investigate the cholesterol-reducing effects and tolerance property of Lactobacteria isolated from Kefir grain in vitro. Method In imitating gastroenteric environments,such as low pH (2.0～4.0) and high bile salt concentration (0.2%-0.4%),the survival counts of Lactobacteria was carried out and cholesterol-reducing effects were studied. Results The strains of KTX,KS4 and KL1 had more survival counts in eaperimental condition and KTX. KS4 were isolated as more tolerant strains to gastro-enteric environments and could reduce cholesterol in vitro. Conclusion Lactobacteria isolated from Kefir grain had tolerant properties and cholesterol-reducing effects in vitro.

Objective To investigate the cholesterol-reducing effects of complex bacteria leaven (CBL) from Kefir Grain milk yoghurt in experimental hypercholesterolemia rats. Method Isolated three strains of Lactobacilli from Kefir Grain milk yoghurt with high activity of bile salf hydrolase and cholesterol-reducing effect and prepare the CBL. Forty rats were randomly divided into four groups: control group, hypercholesterolemia model group, and experimentalⅠ, Ⅱ groups according to serum TC, TG, HDL-C and LDL-C concentrations. Control group was fed basic feed and three other groups were fed high fat feed. Experimental groups were given i.g. the test substances for 8 w, and control and model groups were given water, then serum TC, TG , HDL-C and LDL-C concentrations were determined at the end of the 2nd, 4th, 6th and 8th w. Results Compared with model group, serum TC, TG and LDL-C in experimentalⅠgroup and Ⅱgroup were significantly decreased and HDL-C increased after 8 w of treatments respectively, groupⅠ better than groupⅡ. Conclusion Complex bacteria leaven from Kefir Grain show significant effects of cholesterol-reducing effect in experimental hypercholesterolemia rats.

Objective To explore clinical curative effect of microsurgery of petroclival tumors by transpetrosal presigmoid approach. Methods A series of 23 patients of petroclival tumors resected by microneurosurgery were analyzed retrospectively, including tumors histological types, clinical and preoperative MRI features, operative approaches, surgical technique and common postoperative complications. Results Total resection of the tumor was achieved microsurgically in 16 cases, subtotal resection in 4 cases, partial resection in 3 cases. No patient died in this series. 8 patients presented worsening crainal nerves palsies postoperatively. CSF leaks were uncommon, occuring in 2 patients. Conclusion The tumors in petroclival region can be totally resected by transpetrosal presigmoid approach. The advantages were offered by this approach such as the temporal lobes and cerebellum are minimally retracted; the operative distance of petroclival tumors is shortened with exposure of clivus and juxta-clival region.

OBJECTIVE: To optimize the preparation technology of phloroglucinol phospholipids complex and study its physicochemical properties.METHODS: The preparation technology for phloroglucinol phospholipids complex was optimized taking the molar ratio of phloroglucinol to phospholipids(A),reaction temperature(B) and reaction time(C) as factors and complex ratio of phloroglucinol and phospholipid as index.The dissolubility and oil/water partition coefficient of the complex in different solvents were determined and compared with crude drug,and the new complex's physicochemical properties were validated by UV and IR(infrared spectra).RESULTS: The optimized preparation conditions for phloroglucinol phospholipids complex were obtained as follows: A was 1∶2;B was 60 ℃ and C was 2 h.The complex ratio remained at above 98%.Compared with phloroglucinol crude drug,the phloroglucinol phospholipids complex in water or chloroform showed increase in both dissolubility and oil/water partition coefficient.UV and IR confirmed that no new complex had been formed from phloroglucinol and phospholipids.CONCLUSION: The optimized technology greatly enhanced the dissolubility and lipotropy of the phloroglucinol phospholipids complex.

OBJECTIVE To describe the surgical experience in the repair of cerebrospinal fluid (CSF)rhinorrhea treated by endoscopic transnasal approaches. METHODS From Oct. 2003 to Dec. 2008, 38 patients with CSF rhinorrhea were treated. Endoscopic endonasal approaches and surgical techniques in repair of CSF leaks were reviewed in a series of 38 patients included 21 patients with traumatic CSF leakage, 10 patients with spontaneous CSF leakage, and 7 patients with other reasons. RESULTS Followup of 6 months to 3 years after operation, successful rate at first attempt was 92.1%. Two patients needed a second surgical repair and one patient a third surgical repair. The complications included meningitis and acute obstructive hydrocephalus in two patients respectively. CONCLUSION The endoscopic endonasal approaches is the first choice for repair of CSF leakage for its minimal invasive injury and high successful rate. Leakage site identification, site preparation, accurate graft placement and postoperative management are critical to the success of operation.

OBJECTIVE:To explore the effects of Xinnaoxin pills on CAT score,cardiopulmonary function and hemorheology of patients with pulmonary heart disease complicating with coronary heart disease. METHODS:In retrospective study,80 cases of pulmonary heart disease complicating with coronary heart disease were randomly divided into control group and observation group with 40 cases in each group. Control group was given routine treatment as relieving asthma,eliminating phlegm and oxygen inhala-tion,anti-infective treatment,correcting acid-base balance,cardiotonic and diuretic treatment. Observation group was additionally given Xinnaoxin pills 1.0 g/time,bid after meal,on the basis of control group. CAT score,cardiopulmonary function and hemorhe-ology index were compared between 2 groups before and after treatment as well as ischemic ECG improvement effect and the occur-rence of ADR after treatment. RESULTS:After treatment,hematocrit hematocrit had changed slightly among hemorheology index-es,and CAT score,other hemorheology indexes and cardiopulmonary function indexes were improved significantly;the improve-ment of observation group was better than that of control group,with statistical significance(P<0.05). Total effective rate of isch-emic ECG was 90.0% in control group and 92.5% in observation group,there was no statistical significance(P>0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Xinnaoxin pills can effectively improve CAT score and cardiopulmonary function of patients with pulmonary heart disease complicating with coronary heart dis-ease. It also can improve hemorheology and shows good clinical efficacy,but great importance should be attached to the safety of drug use in the clinic.
