Aldose reductase (AR) mRNA level in peripheral blood mononuclear cells was assayed by RT-PCR. There was a positive correlation between PBMC AR mRNA level and urinary albumin excretion rate in type 2 diabetic patients. The result suggests that AR activity is related to the pathogenesis of diabetic nephropathy.

Objective:To evaluate the quality of carbazochrome sodium sulfonate Injection from different manufacturers, analyze the existing problems and provide the reference for the improvement of clinical medication safety. Methods:Statutory testing methods and the exploratory research methods were used to examine the samples, and the quality status of carbazochrome sodium sulfonate Injec-tion was evaluated according to the results. Results:Totally 89 batches of the samples were tested by the current standard. The quali-fied rate was 97. 8%, and the two batches of unqualified samples were carbazochrome sodium sulfonate and sodium chloride Injection with unqualified insoluble particles. Overall, the quality risk of carbazochrome sodium sulfonate for injection was low, and the safety of carbazochrome sodium sulfonate and sodium chloride Injection needed further research. Conclusion:The quality of carbazochrome so-dium sulfonate Injection basically meets the current standard, and the exploratory research suggests that the current standard is imper-fect. It is urgent to improve the related substance detection in the standard and determine the reasonable limits for the degradation im-purities and the other impurities. The clinical medication safety of carbazochrome sodium sulfonate and sodium chloride Injection needs further research.

Objective:To guide antithrombotic medication in the patients with PCI by GRACE and CRUSADE risk score. Meth-ods:The GRACE and CRUSADE score at the admission of 147 patients with ACS undergone PCI in one 3-level hospital were analyzed, and the two risk scores of the PCI patients and the correlation between the two scores were studied. Results:The risk factors in the two scores were part of the same, and the two scores had significant positive correlation. Conclusion: The GRACE score and CRUSADE score should be assessed at the same time in clinics to weigh the risk of bleeding and ischemia fully and then develop strategies for an-tithrombotic treatment.

ObjectiveTo evaluate the impacts of pereutaneous nephrolithotomy (PCNL) on perioperative renal hemodynamics.MethodsThe hemodynamics of operated renal arteries of 30 patients who underwent unilateral PCNL with single pole access were observed 1 day before and 5-7 days after operation with CDFI.Parameters were analyzed statistically.ResultsAfter operation,resistance index (RI) of renal arteries decreased (P＜0.05).The diastolic flow statistically increased at main renal artery (MRA) of renal hilus,interlobar renal artery and interlobular renal artery (all P＜0.05).After PCNL,in serious hydronephrosis patients,RI decreased (P＜0.05) at segmental renal artery (SRA) and interlobar artery,end-diastolic flow velocity (Vmin) increased at interlobar renal artery (P＜0.05).In moderate hydronephrosis patients,RI decreased at all renal arteries (P＜0.05) after PCNL,Vmin increased at MRA and interlobular renal artery (P＜0.05).In minor hydronephrosis patients,RI decreased at MRA and SRA,Vmin increased at SRA.In patients without hydronephrosis,RI changeed like serious hydronephrosis patients.ConclusionAfter PCNL,ipsilateral renal perfusion improves,renal diastolic flow increases and RI decreases.CDFI can be used to observe the blood perfusion of kidney,and provide quantitative information of renal hemodynamics.

Objective To analyse the therapeutic outcome of cavernous sinus meningiomas by gamma knife radiosurgery. Methods Retrospective analysis was conducted of 37 patients with cavernous sinus meningiomas. The median maximum diameter was 2.6 cm (1.4～3.2 cm) with the median dose to the tumor margin of 15.7Gy(8～22 Gy), the isodose curve to the tumor margin of 40%～60% and the target numbers of 1～9. The radiosurgical dose to the optic nerve and brain stem was not more than 10 Gy and 15 Gy, respectively. Results After an average follow up of 22.6 months(ranging 4～43 months), unchanged symptoms were found in 22 cases(59.5%), alleviated in 12 cases(32.4%) and complications of optic and trigeminal nerve in 3 cases(8.1%). By MR image analysis, unchanged size was found in 18 cases(48.6%), smaller size in 15 cases(40.5%) and larger size in 4 cases(10 8%). One factor analysis of variance revealed that tumor recurrence was associated with marginal dosage(

Objective: To systematically evaluate the clinical effect of Xiaoke Decoction in the treatment of type 2 diabetes. Methods: Chinese databases such as CNKI, Wanfang, Weipu Chinese Biomedical Journal Database, and Chinese Medical Biological Literature Database, PubMed, Cochrane Library, Embase, and Web of Science were searched for English language literature from their inception until November 2019. A Meta-analysis was performed using RevMan 5.3 and Stata 12.0. Results: Thirty-eight studies were included in this study, with a total of 3757 patients. It was found that adding Xiaoke Decoction could improve total efficiency. The Xiaoke Decoction groups surpassed the western medicine groups regarding improvement in total efficiency (OR = 3.49; 95% CI: 2.78–4.39, P < 0.00001). Adding Xiaoke Decoction could lower the fasting plasma glucose (FPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in FPG levels (MD = −1.14; 95% CI: −1.36 to 0.92, P < 0.00001). Adding Xiaoke Decoction could lower the 2 h postprandial blood glucose (2hPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in 2hPG (MD = −1.40; 95% CI: −1.61 to 1.19, P < 0.00001). Adding Xiaoke Decoction could lower glycated hemoglobin (HbA1c). The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in HbA1c (MD = −0.77; 95% CI: −0.95 to 0.58, P < 0.00001). It was found that adding Xiaoke Decoction could lower the traditional Chinese medicine (TCM) syndrome score. The TCM syndrome scores among patients in the Xiaoke Decoction group were lower than those among patients in the control group after treatment (MD = −4.90; 95% CI: −7.22 to 2.57, P < 0.0001). At the same time, we conducted a subgroup and sensitivity analysis of age and intervention duration on the heterogeneity of total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score outcome indicators. For detecting publication bias, an egger test was conducted. Conclusion: Compared with western medicine alone, Xiaoke Decoction has more advantages for the treatment of type 2 diabetes with respect to total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score.

The plants in genus Gentianella Moench (Gentianaceae) which comprised approximately 250 species, are mainly distributed in temperate regions of the world.Many Gentianella plants are intensely bitter and employed in traditional medicine to stimulate appetite, treat disorders of the gallbladder, and treat fever like the other bitter gentians in various regions of the world.Some species exhibit other remarkable therapeutic effects in the treatments of obesity,diabetes, and heart diseases.Eleven iridoids, twenty-eight xanthones, three C-glucoflavonoids, and eight other compounds have been isolated from the genus.Most of these compounds are associated with antimicrobial,anti-inflammatory, anti-oxidant, hypoglycemic, and antitumor activities, which provide an empirical base for the traditional utilization of the plants in genus Gentinella Moench.

Objective To investigate the accuracy of predicting acute postoperative pain by assessment of intravenous propofol injection-induced pain.Methods Seventy-one ASA I or Ⅱ patients aged 20-40 yr scheduled for induced abortion operation were enrolled in this study. The patients were unpremedicated. ECG, HR, BP and SpO_2 were continuously monitored before and during anesthesia. Anesthesia was induced with 2 mg/kg propofol. A third of the induction dose was injected via a dorsal hand vein. Pain induced by iv propofol injection was assessed with verbal rating scale (VRS) (0 = no pain, 3 = severe pain) . Postoperative abdominal pain was assessed with visual analog scale (VAS) (0 = no pain, 100 = most severe pain) at 20 min after operation. Results The propofol injection pain occurred in 66% of patients. Postoperative VAS scores at rest and during activity and intravenous propofol injection-induced pain were significantly correlated (r = 0.561, P<0.01; r = 0.608, P<0.01). The sensitivity and specificity of iv propofol injection-induced pain (VRS > 1) in predicting clinically significant acute postoperative pain (VAS > 30) were 96% and 52% respectively. Conclusion Preoperative iv propofol injection induced pain is a reliable factor in predicting acute postoperative pain and is useful in identifying those women who will experience greater pain after operation.

Objective To evaluate the application of time to positivity (TTP)in differential diagnosis of intracranial infection caused by coagulase-negative Staphylococcus (CNS).Methods One hundred and twenty-four adult patients with positive CNS isolated from cerebrospinal fluid (CSF)including 70 cases with intracranial infection and 54 cases of CSF contamination,who were admitted in Xiangya Hospital of Central South University during January to December 201 5,were retrospectively analyzed.The difference of TTP between two groups was compared,receiver operating characteristic (ROC)curve was analyzed and the area under the ROC curve (AUC)was calculated.The application of TTP in differential diagnosis of CNS infection was evaluated.SPSS 1 8.0 software was used to analyze the data.Results TTP in intracranial infection group was shorter than that in CSF contamination group [(23.5 ±7.5 )h vs. (37.6 ±1 0.5)h,t =-8.71 7,P =0.000].The AUC of TTP was 0.854.Taking the cut-off value of 27.94 h,the sensitivity,specificity,positive and negative predictive values in differentiation of two groups were 72.7%,91 .4%,90.0% and 72.2%,respectively.There were statistically differences in TTP of Staphylococcus epidermidis,Staphylococcus haemolyticus and Staphylococcus capitis between two groups (Z =-4.496,-2.322 and -2.399,respectively,P <0.05 or <0.01 ).Conclusion TTP can be used to discriminate early intracranial infection and CSF contamination caused by CNS,and also can identify intracranial infection caused by different categories of CNS.

OBJECTIVEThe effect of light intensities on the endogenous hormones of Bletilla striata during seedling acclimatization was studied in order to explain the mechanism and provide basic data for conservation and cultivation of this wild medicinal species.

METHODThe samples was treated with three photosynthetic photon flux densities: 3 000, 6 000, 12 000 lx during the acclimatization stage to study the hormone dynamic changes of IAA, ABA, GA3.

RESULTEndogenous IAA concentration was declined in all treatments and the lowest level in all treatments was the middle light intensity. A sharp increase of endogenous ABA concentration in a short period, the concentration was increased by 380.2% in middle light (320.8 ng x g(-1)). Endogenous GA3 concentration was declined especially in the high light treatment. At 10 days of acclimatization the GA3 concentration was decreased by 52.2% in the high light (473.6 ng x g(-1)).

RESULTEndogenous hormones concentration could be rapidly changed by the light, and endogenous ABA concentration could be sharply increased when acclimatization in middle light intensities.
