Objective To investigate the effect of Kunxian capsule combined with candesartan axetil on blood pressure, renal function, blood lipids and inflammatory factors in patients with chronic glomerulonephritis complicated with hypertension. Methods 101 patients with chronic glomerulonephritis who were admitted to our hospital from November 2017 to December 2019 were selected and randomly divided into observation group (51 cases) and control group (50 cases). The control group was treated with candesartan cilexetil on the basis of conventional treatment, and the observation group was treated with Kunxian capsule on the basis of the control group. The clinical efficacy and adverse reactions of the two groups were compared. Results The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the blood pressure, renal function indexes (24 h Upro, BUN, Scr), blood lipid indexes (TG, TC, LDL-C), and inflammatory factors of the two groups (IL-6, hs-CRP) significantly decreased, and the observation group was significantly lower than the control group (P<0.05). After treatment, the blood lipid index HDL-C of the two groups increased significantly, and the blood lipid index HDL-C of the observation group was significantly higher than that of the control group (P<0.05). Conclusion Kunxian capsule combined with candesartan axetil can enhance the clinical efficacy, improve renal function, regulate blood lipids and reduce inflammation in patients with chronic glomerulonephritis complicated with hypertension.

Objective:In order to accurately evaluate the postoperative rehabilitation of gynecological robotic surgery, a prediction model for evaluating postanesthesia care unit (PACU) extubation time and hospital stay in gynecological robotic surgery was established.Methods:The clinical data of gynecological patients who underwent robotic surgery in Xiangya Third Hospital of Central South University from October 2015 to May 2017 were retrospectively analyzed, and the data were screened to evaluate the postoperative recovery of patients from two aspects: PACU extubation time and postoperative hospital stay. Binary logistic regression was used to screen out the factors affecting PACU extubation time and postoperative hospital stay, and the prediction model was preliminarily established and verified.Results:Finally, there were 456 patients and 30 variables analyzed in the binary logistics regression. According to these variables, the prediction model of the postoperative recovery evaluation after gynecological robotic surgical procedures was established. Among them, age, intraoperative amount of atracurium and midazolam were independent risk factors affecting PACU extubation time (all P<0.05). American Society of Anesthesiologists (ASA) grade, intraoperative amount of midazolam, intraoperative bleeding and operation time were independent risk factors affecting postoperative hospital stay (all P<0.05). All models passed Hosmer lemeshow test (all P>0.05); The areas under the receiver operating characteristic curve (ROC) were 0.647 and 0.806, respectively. Conclusions:The prediction model of PACU extubation time and the postoperative hospitalization time has been established.

The massive loss of oligodendrocytes caused by various pathological factors is a basic feature of many demyelinating diseases of the central nervous system (CNS). Based on a variety of studies, it is now well established that impairment of oligodendrocyte precursor cells (OPCs) to differentiate and remyelinate axons is a vital event in the failed treatment of demyelinating diseases. Recent evidence suggests that Foxg1 is essential for the proliferation of certain precursors and inhibits premature neurogenesis during brain development. To date, very little attention has been paid to the role of Foxg1 in the proliferation and differentiation of OPCs in demyelinating diseases of the CNS. Here, for the first time, we examined the effects of Foxg1 on demyelination and remyelination in the brain using a cuprizone (CPZ)-induced mouse model. In this work, 7-week-old Foxg1 conditional knockout and wild-type (WT) mice were fed a diet containing 0.2% CPZ w/w for 5 weeks, after which CPZ was withdrawn to enable remyelination. Our results demonstrated that, compared with WT mice, Foxg1-knockout mice exhibited not only alleviated demyelination but also accelerated remyelination of the demyelinated corpus callosum. Furthermore, we found that Foxg1 knockout decreased the proliferation of OPCs and accelerated their differentiation into mature oligodendrocytes both in vivo and in vitro. Wnt signaling plays a critical role in development and in a variety of diseases. GSK-3β, a key regulatory kinase in the Wnt pathway, regulates the ability of β-catenin to enter nuclei, where it activates the expression of Wnt target genes. We then used SB216763, a selective inhibitor of GSK-3β activity, to further demonstrate the regulatory mechanism by which Foxg1 affects OPCs in vitro. The results showed that SB216763 clearly inhibited the expression of GSK-3β, which abolished the effect of the proliferation and differentiation of OPCs caused by the knockdown of Foxg1. These results suggest that Foxg1 is involved in the proliferation and differentiation of OPCs through the Wnt signaling pathway. The present experimental results are some of the first to suggest that Foxg1 is a new therapeutic target for the treatment of demyelinating diseases of the CNS.

Objective To explore the level of serum hypoxia-inducible factor (HIF)-1α and the effect of pantoprazole on HIF-1α in patients with gouty arthritis.Methods Subjects were divided into acute gouty arthritis (group A),intermittent gouty arthritis (group B) and healthy controls (group C).Patients in group A were divided into mild (A1) and severe (A2) subgroups according to the severity of inflammation.Levels of serum HIF-1α in the three groups,and the levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in group A1 and group A2 were detected by enzyme-linked immunosorbent assay (ELISA).Patients in group A2 were randomly divided into three groups,saline 100 ml/twice a day,20％ pantoprazole 100 ml,twice a day and 40％ panto-prazole 100 ml,twice a day were administered respectively.After 7 days,the levels of serum HIF-1α were measured by ELISA.One-way analysis of variance (ANOVA) and two independent sample t test were conducted in this study.Results ① Levels of serum HIF-1α in group A [(48±13) ng/L] were significantly higher than those in group B [(40±12) ng/L,P＜0.01] and group C [(28±12) ng/L,F=29.838,P＜0.01].② Levels of serum HIF-1α [(56±10) ng/L],IL-1β [(51 ±13) ng/L] and TNF-α [(161 ±45) ng/L] in the experimental group A2 were higher than those in the experimental group A1 [HIF-1α:(42±11) ng/L,t=4.600,P＜0.01;IL-1β:(42±12) ng/L,t=2.552,P＜0.05;TNF-α:(122±34) ng/L,t=3.432,P＜0.01].③ Levels of HIF-1α [(26±6) ng/L],IL-1β [(23±4) ng/L],TNF-α [(92±6) ng/L] in the 40％ pantoprazole group were lower than those in 20％ pantoprazole 100 ml,twice a day group [HIF-1α:(33±4) ng/L];IL-1β:(30±5) ng/L;TNF-α:(102±7) ng/ L] and saline group [HIF-1α:(37±5) ng/L];IL-1β:(38±5) ng/L];TNF-α:(108±9) ng/L](all P＜0.05);Levels of HIF-1α,IL-1β and TNF-αin the 20％ pantoprazole group were lower than those in saline group (all P＜0.05).Conclusion ① HIF-1α may be one of the indicators of acute inflammation,which may reflect the degree of inflammation in patients with gout.② Pantoprazole can reduce the level of serum HIF-1α,IL-1β and TNF-α in patients with gouty arthritis,with a concentration dependent characterisit.

Objective To study the incidence rate of prostate cancer detected in the specimen of radial cystoprostatectomy for bladder cancer and to evaluate its effect on the prognosis.Methods From June 2012 to June 2017,the clinical data of 132 patients with bladder cancer undergoing radical cystectomy (RCP) were analyzed retrospectively.The average age of 132 patients with bladder cancer was 61.2 years (37-89 years old).The serum of PSA of 89 cases out of 132 patients was examined before operation,21 cases 4 ng/ml ＜ tPSA ＜ 10 ng/ml,1 case tPSA 17 ng/ml and 67 cases tPSA ＜ 4 ng/ml.The pathology of bladder and prostate,the location and range of prostate cancer and Gleason score and the prognostic effect of prostate cancer was evaluated.Results The 132 patients with bladder cancer,116 cases (87.9％) were high grade urothelial carcinoma,8 cases (6.0％) were bladder carcinoma in situ,6 cases (4.5％) were low grade urothelial carcinoma,1 case was neuroendocrine bladder carcinoma and 1 case was signet ring cell carcinoma.The 21 cases of prostate cancer were combined with Gleason score,among which 3 + 2 score in 1 cases,3 +3 score in 17 cases,4 +3 and 3 +4 in 1 cases,and 4 +5 score in 1 cases.The lesions were unilateral in 14 cases and bilateral in 7 cases.The lesions were ＜0.5 ml in 3 cases,0.5-0.7 ml in 14 cases and 0.7-1.0 ml in 4 cases.The average age of 21 cases with prostate cancer was 67.5 years old (41-89 years).Of the 21 cases of prostate cancer,the serum tPSA was abnormal in 4 cases with an average of 8.8 ng/ml (4.2-17.0 ng/ml),the serum tPSA was normal in 12 cases with an average of 2.5 ng/ml (1.3-3.7 ng/ml),and the serum PSA in 5 cases was not detected before operation.Three cases of prostate cancer aged less than 60 years old with the detection rate of 9.6％ (3/31);18 cases were equal or older than 60 years old with the detection rate of 17.8％ (18/101).Multi parameter analysis showed that the incidence of prostate cancer increased with the age of the patients (OR =1.36,P =0.048).Followed up for 5 to 51 months,no PSA relapse was found and no patient receiving related treatment.Conclusions The detection rate of prostate cancer is very high in the specimen of radial cystoprostatectomy for bladder cancer.The clinical manifestation of the prostatic involvement is concealed.Radical resection of the prostate is necessary in radical resection of bladder cancer.

Objective To compare the clinical values of impedance method,optical method and microscopy when used to detect platelet abnormal results.Methods Platelet re-examinations by optical method and microscopy were carried out in case of low confidence degree in platelet test with impedance method by XE-2100 automatic hematology analyzer,and then the results by the three methods were compared.Results Most of the low-confidence-degree results by impedance method could be corrected by re-examination by optical method,and the remained had to turn to microscopy due to unsatisfied requirements of the instrument.Conclusion Optical method has to be involved to correct the platelet abnormal results by XE2100 automatic hematology analyzer,and microscopy should be applied in case optical method doesn't work.The three methods gains advantages and disadvantages of themselves,and can be supplementaries for one another.

Objective To evaluate the efficacy and safety of DA-EPOCH-R protocol for patients with B-cell non-hodgkin lymphoma (NHL). Methods 43 patients with B-cell NHL received DA-EPOCH-R protocol, and their efficacy and adverse reactions were analyzed. Results 43 patients received a total of 203 cycles of chemotherapy and the median chemotherapy cycle was 6 (2ˉ8 cycles). 32 patients (74.4%) achieved complete remission (CR) after 2ˉ4 cycles of chemotherapy. A further analysis found that age ≤60 years and>60 years, stageⅠ/Ⅱand stageⅢ/Ⅳ, germinal center B-cell (GCB), non-GCB, double expression lymphoma (DEL) and non-DEL patients had no significant differences (P> 0.05). With a median follow-up of 40 months (9ˉ62 mouths), the overall survival (OS) rate of 1-year and 3-year was 97.6 % and 92.8 % respectively. The major toxicity of DA-EPOCH-R protocol was hematologic toxicity. Other toxicities were mild, and no treatment-related deaths occurred. At the end of follow-up, no secondary tumors were found. Conclusions DA-EPOCH-R protocol is an effective and safe protocol for patients with NHL. The result shows that the curative effect of patients in stageⅢandⅣis similar to the patients in stageⅠandⅡ.

Objective To observe the effect of stress on the rapid component of delayed rectifier potassium current (IKr) in rat cardiomyocytes. Methods Forty male SD rats were randomly divided into four groups (10 each): control group (Ctrl), exhaustive group (ES), noise group (WN) and composite group (ES+WN). Stress animal models were prepared as follows: Rats in ES group were undergoing exhaustive swimming as the stress factor, in WN group undergoing white noise and in ES+WN group undergoing exhaustive swimming + white noise as the stress factor. Langendorff device was used to reversely perfuse collagenase for isolating the rat's ventricular myocytes. The effect of stress on IKr current and gating mechanism of single ventricular myocyte was recorded by whole-cell patch clamp technique. Results Compared with the Ctrl group, the tail current density of IKr (IKr,tail) of ventricular myocytes increased significantly in ES group and WN group (P<0.01). The IKr,tail current density of the ventricular myocytes in ES+WN group was significantly higher than that in ES group and WN group (P<0.01), and the effect was voltage dependent. Gating mechanism revealed that the half inactivation voltage of IKr,tail (V1/2,inact) can be shifted to the right in ES group, WN group and ES+WN group when compared with the Ctrl group, and the recovery time constant shortened after inactivation (P<0.01). However, the steady-state activation, fast inactivation constant and voltage dependence of IKr,tail were not statistically significant in ES group, WN group and ES+WN group when compared with the Ctrl group. Conclusion Stress increases the IKr current in rat cardiomyocytes, suggesting it be one of the electrophysiological bases of stress-induced arrhythmia.
