OBJECTIVE To analyze antibiotic usage of inpatients in an internal medicine department,probe into the features of antibiotic usage and provide rference for the rational clinical drug-use.METHODS We selected randomly 3102 samples from inpatients in our Internal Medicine Department during the period from Jan to Jun,2007,and analyzed the situation of the antibiotic application.RESULTS The percentage of antibiotic application was 66.18% among 3102 patients,totally 28 kinds from 10 species of antibiotics were used.Cephalosporins and quinolones were mostly applied,and more often they were used in combination.CONCLUSIONS Medication frequency of cephalosporins and quinolones ranks the first in the DDDs,and remains as the primary choice of anti-infectives used.

[Objective]To evaluate the role of mature cumulus cells from oocyte-cumulus complex(OCC)in in-vitro maturation(IVM)and establish a new culture technique which is convenient to carry out.[Methods]The cumulus cells of OCC were cut off and dispersed by 1 mL syringe.The cumulus cells were co-cultured with the immature oocytes retrieved from the COH cycles after they adherent to the bottom of the dish.The immature oocytes were experienced IVM procedures in different culture media.They were divided into 3 groups(the oocytes at germinal vesicle stage from one woman were allotted to the same group randomly).Group 1(solution A):basic culture medium+human follicular fluid(hFF);Group 2(solution B):solution A+ cumulus cells(OCC);Group 3(solution C):solution A+ OCC+ follicle stimulating hormone(FSH)+ epidermal growth factor (EGF).Then,the maturation rate,fertilization rate and formation rate of available embryo were observed.[Results]In 113 treatment cycles,298 immature oocytes were performed IVM with solution A,B,and C.The difference for 24 hour maturation rates among 3 groups wag statistically significant(A:45.2%,B:61.7%,C:78.2%,P＜0.05).There was no statistical difference for 25～48 hour maturation rates and normal fertilization rates of mature oocytes.The differences of cleavage rates and rescued embryo rates between group 1 and 2,group 1 and 3 were statistically significant(P＜0.05).The formation rates of available embryo showed an increasing trend from group 1,2,to 3.[Conclusion]After being dispersed by simply beat upon with syringe and adherent culture,the mature cumulus eells from mature OCCs in COH cycles,together with growth factors in the follicular fluid or extraneously supplemented,could promote the IVM of immature oocyte.

This study aimed at investigating the effects of Chinese herbal compound Qi Kui granules on urine protein and inflammatory markers in patients with type 2 diabetic nephropathy (DN) based on the treatment of regular western medication.A randomized,parallel controlled method was involved in the present trial,and patients diagnosed with type 2 DN were randomly divided into the Chinese herb group and the control group.Regular treatment of angiotensin Ⅱ receptor blocker (ARB) in western medicine was administered in the two groups with the additional treatment of Qi Kui granules for the Chinese herb group.All the patients revisited the doctor every 4 weeks during the observation period within a 12-week course of the observation.Urinary albumin to creatinine ratio (UACR),urinary albumin excretion rate (UAER) and inflammatory cytokines in the two groups were determined.As a result,seventy-two patients in aggregate were included in the study,while 32 patients of the control group and 31 patients of the Chinese herb group effectively accomplished the observation.After the 12-week treatments,UACR and UAER were significantly decreased in the two groups (P ＜ 0.01),while the efficacy of the Chinese herb group was better than that of the control group (P ＜ 0.05).Compared with the control group,the levels of serum IL-6,tumor necrosis factor α (TNF-α),transforming growth factor f1 (TGF-f1) and urinary monocyte chemoattractant protein (MCP-1) / Cr significantly decreased after the 12-week treatment (P ＜ 0.01).It was concluded that the Chinese herbal compound Qi Kui granules successfully mitigated proteinuria in DN patients.The improvement of glomerular inflammation for renoprotection should be the mechanism behind this.

Objective:To investigate the effect of ultrasound-guided early removal of indwelling catheter on recovery quality and catheter-related infection of patients with general anesthesia in post anesthesia recovery unit (PACU).Methods:From September 2019 to April 2020, 146 patients with gynecological benign diseases who underwent hysteroscopic surgery in the Department of Anesthesiology, Shenzhen Hospital of Southern Medical University were selected prospectively and randomly divided into two groups, with 4 cases excluded. The function of the bladder was evaluated by ultrasound in the anesthesia recovery room after operation. In the ultrasound group, 71 patients had no abnormality, and the catheter was removed after the residual urine of the bladder was drained. 71 patients in the control group were normal, and the catheter was removed 24 hours after operation. The residual urine volume, urine retention, incidence of restlessness, urinary tract infection rate, time to first walking and hospital stay were observed in the two groups after the first bladder emptying.Results:The incidence of agitation in PACU was 7.0%(5/71) in the ultrasound group and 22.5%(16/71) in the control group, with statistically significant difference ( P<0.01); the first postoperative walking time in the ultrasound group and the control group was statistically significant [(10.5±4.1)h vs (18.9±6.5)h, P<0.05]; the postoperative hospital stay in the ultrasound group and the control group was statistically significant [(3.2±1.3)d vs (5.1±2.5)d, P<0.05]. The incidence of urinary tract infection and urinary tract irritationin in ultrasound group was significantly lower than that in control group (1.4% vs 9.8%, 1.4% vs 14.0%, P<0.05). Conclusions:For uncomplicated patients after gynecological laparoscopic surgery, ultrasound evaluation of bladder function, extraction of residual urine immediately after the removal of catheter, is more conducive to the early recovery of patients than 24 hours after the removal of catheter.

Objective: To investigate the relationship between gut microbiota structure and biochemical changes in patients with different types of nonalcoholic fatty liver disease (NAFLD), in order to provide evidence for clinical diagnosis and prevention of NAFLD. Methods: Forty-eight NAFLD cases (NAFLD group), 40 NAFLD cases with type 2 diabetes mellitus (NAFLD combined with type 2 diabetes mellitus group) and 30 healthy cases (healthy group) were randomly enrolled, and their body mass index, serum alanine aminotransferase, aspartate aminotransferase, total bilirubin, total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein and uric acid were measured. Serum levels of TNF-alpha and fasting insulin were measured using ELISA, and then insulin resistance index was calculated. The gut microbiota of three groups of subjects was detected using 16S rDNA-based high-throughput sequencing. Lastly, the correlations between the various factors were analyzed. The comparison among groups was conducted by 2 test, and one-way ANOVA was used for comparison among groups with normal distribution and homogeneity of variance. Furthermore, the LSD method was used to compare the two groups. K-W rank sum test was used for comparison among groups without normal distribution or homogeneity of variance. Results: Body mass index, aspartate aminotransferase, triglyceride, total cholesterol, low density lipoprotein, uric acid, tumor necrosis factor-alpha, fasting insulin and insulin resistance index of NAFLD group were higher than healthy group, while the high-density lipoprotein was lower in the healthy group, and the difference was statistically significant (P< 0.05). Compared with NAFLD group, the life expectancy, fasting blood glucose and insulin resistance index of NAFLD combined with type 2 diabetes mellitus group were higher, while the body mass index, aspartic acid aminotransferase, total cholesterol and HDL levels were decreased, and the difference was statistically significant (P< 0.05). NAFLD group (P= 0.016) had decreased abundance of firmicutes than healthy group, and the abundancy of the firmicutes in the NAFLD combined with type 2 diabetes group was significantly lower (P< 0.001). The abundance of bacteroidetes in NAFLD combined with type 2 diabetes group was higher than healthy group, and the difference was statistically significant (P= 0.006). At the "genus level," the abundance of Roseburia and Subdoligranulum in the NAFLD group was decreased, while the Roseburia in the NAFLD group with type 2 diabetes group was significantly lower (P< 0.05). In addition, the abundance of Faecalibacterium, Blautia, Anaerostipes and Fusicatenibacter in NAFLD combined with type 2 diabetes group was lower than healthy group, and the difference was statistically significant (P< 0.001). Fusicatenibacter, Blautia, Anaerostipes, Faecalibacterium, and Roseburia were negatively correlated with fasting blood glucose and insulin resistance index levels (r< 0,P< 0.05), and positively correlated with high-density lipoprotein levels (r> 0,P< 0.05). Fusicatenibacter was negatively correlated with tumor necrosis factor-alpha (r= -0.211,P= 0.044), and Lachnoclostridium was positively correlated with body mass index, alanine aminotransferase, aspartate aminotransferase levels (r> 0,P< 0.05). Fusobacterium was positively correlated with aspartate aminotransferase level (r= 0.245,P= 0.019). Escherichia-shigella was positively correlated with fasting blood glucose, low-density lipoprotein, alanine aminotransferase, aspartate aminotransferase levels (r > 0,P< 0.05). Megamonas was negatively correlated with high-density lipoprotein levels (r= -0.231,P= 0.027). Conclusion A structural change of gut microbiota had occurred in patients with NAFLD, suggesting changes in some of these bacterial genuses had relation to insulin resistance and inflammatory response, which may become a new target for the treatment of NAFLD.
