Objective:To evaluate the function of bladder after gastrocystoplasty.Methods:38 patients after gastrocystoplasty were analyzed by observing the micturition and examination of urodynamics and to investigate the function of bladder during the filling and the micturition.Results:In the 38 patients,voiding interval time was 3.2?1.7hours;unirary output was 320?110ml;maximual flow rate was 19?7.2 ml per second;intravcsical pressure during filling was 11.2?8.2 cmH 2O;maximual intravesical pressure during voiding was 58?21 cmH 2O;and maximual pressure of detrusor was 28?12 cmH 2O.In total 38 cases,residual urine was observed in 11 cases,and residual volume was 55?34ml.12 cases developed uracratia or enuresis.Conclusion:Filling function of bladder is satisfactory after gastrocystoplasty,the micturition is carried out mainly by the action of intra-abdominal pressure.The disturbance of function of the sensation of bladder and the urethral sphincter is possibly the common cause for uracratia or enuresis.

Objective A high performance liquid chromatographic (HPLC) method was established for the determination of glycerol in propofol medium and long chain fat emulsion injection.MethodsThe chromatographic conditions were as follows: Kromasil 100-5-NH2 column(4.6×250mm,5μm) with the column temperature was 40℃,acetonitrile-water(8515)as mobile phase with flow rate of 1.0mL/min.Glycerol was detected by refractive index (RI) detector at 40℃.ResultsThe linear range of glycerol was 455.3916-2276.9580μg/mL(r=0.9999,n=7),the average recovery rate was 99.5%,RSD was 0.6%(n=9),the limit of detection(LOD) was 121ng and the limit of quantification(LOQ)was 364ng.ConclusionThe method was simple, rapid, strong specifity and accurate with good reproducibility, which is suitable for the content determination of glycerol in propofol medium and long chain fat emulsion injection.

Objective:To explore the effects of gentiana scabra bage on the expression of hepatic collagen proteins in Paragonimus skrjabinirats with liver fibrosis.Methods:Immunohistochemical technique was used to observe the changes of content of hepatic type Ⅰ, Ⅱ collagen proteins in Paragonimus skrjabinirats with liver fibrosis before and after the gentiana scabra bage treatmeat. Results:Comparing with the model group, changes of hepatic type Ⅰand type Ⅱ collagen proteins in gentiana scabra bage treated group were significantly weakened.Conclusions:Gentiana scabra bage treatment can reduce the content of hepatic type Ⅱ and typeⅠcollagen protein significantly in Paragonimus skrjabinirats with liver fibrosis, thereby, playing the role against hepatic fibrosis.

To investigate the freshness, high molecular weight substances, the determination of polypeptide, haemolysis and agglomeration, biological activity of Cervus and Cucumis polypeptide injection; to provide the direction for improving the quality of products for enterprises; furthermore, to provide reference for the revision of the quality standards of Cervus and Cucumis polypeptide injection. Firstly, we investigated the factors affecting the freshness of the injection, including biogenic amines, aflatoxins, the acid value and peroxide value of the melon seeds. The method of dansyl chloride pre-column derivatization-HPLC was used to determine the content of 8 biogenic amines in Cervus and Cucumis polypeptide injection. The method validation results showed good specificity, precision, linearity and recovery rates, which was suitable for the determination of biogenic amines in Cervus and Cucumis polypeptide injection. The results of sample determination showed that relatively higher concentrations of cadaverine were detected in the products from company B. The results of aflatoxins, acid value and peroxide value showed that the melon seeds from some companies had rancidity, mildew and other problems, indicating that the quality standards of multi-component biochemical drugs containing animal- and plant-derived components should be controlled in terms of freshness. Secondly, the methods for the determination of high molecular weight substances and polypeptides in the quality standard were improved. Tricine-SDS-PAGE electrophoresis was used instead of gel chromatography to determine the high molecular weight substances, which improved the accuracy of determination. The kits were used instead of folin-phenol for the determination of peptide content, which is easy to operate, specific and suitable for high-throughput sample determination. Finally, the haemolysis, agglomeration, and biological activity of Cervus and Cucumis polypeptide injection were studied. The results showed that no haemolysis and agglomeration were found in all samples, and the inhibitory effect of samples on THP-1 proliferation in vitro from different companies was different to some extent. In conclusion, the optimized quality standard is more suitable for the detection of Cervus and Cucumis polypeptide injection, and can lay the foundation for improving the safety of multi-component biochemical drugs.

To investigate the clinical features of patients with PLA2G6 gene related early onset Parkinson syndrome (EOP) with cerebellar atrophy, the clinical data of 3 hospitalized EOP patients with PLA2G6 gene mutation were collected in Xuanwu Hospital, Capital Medical University, and the clinical characteristics, imaging features and genetic testing results were comparatively analyzed. Related literatures were also reviewed. Cerebellar atrophy was observed on cranial magnetic resonance imaging in all 3 patients with Parkinson syndrome except for extrapyramidal symptoms. All 3 patients had heterozygous mutations of PLA2G6 gene, and the common mutation site of c.991G>T (p. D331Y) was found in 2 patients by second-generation sequencing. This report enlarges the clinical phenotypic spectrum of the disease and helps to better understand the disease.

Objective:To explore the clinical characteristics of cryptococcus neoformans patients who suspected as lung cancer and treated with surgery, and to improve the diagnosis of the disease.Methods:A retrospective analysis on clinical data(including preoperative laboratory examination, chest CT imaging and postoperative pathology) of 21 cryptococcosis neoformans patients misdiagnosed as lung cancer in our hospital from February 2016 to July 2019.Results:Among the 21 patients, 17 cases were single nodules and 4 cases were multiple nodules, among which 15 cases were highly suspected malignancy. The postoperative pathological diagnosis was cryptococcal pulmonary granulomatosis. 14 patients were treated with antifungal therapy after surgery. No recurrence was found after postoperative follow-up.Conclusion:The clinical manifestations and imaging examination of pulmonary cryptococcus neoformans patients have no obvious specificity, and it is easy to be misdiagnosed as early lung cancer. The diagnosis can only be confirmed by the combination of various means such as regular follow-up, laboratory examination, percutaneous lung puncture or surgical biopsy.

Objective:To investigate the application value of fluorescence imaging in single-port thoracoscopic anatomic segmentectomy.Methods:The clinical data of 280 patients (145 patients with fluorescence method and 135 patients with modified inflation-deflation method) who underwent thoracoscopic anatomic segmentectomy were retrospectively studied in the Anhui Chest Hospital from June 2020 to June 2021. There were 113 patients in the simple segmentectomy group and 167 patients in the complex segmentectomy group. The baseline data of the fluorescence method and the modified inflation-deflation method in the complex segmentectomy group were corrected by propensity score matching, and the perioperative results were compared between the groups.Results:There were no significant differences in segmental resection time, intraoperative blood loss, postoperative drainage, postoperative pain, postoperative extubation time, length of hospital stay, incidence of complications and cost of hand-holding between the fluorescence method and the modified method of the simple segmentectomy group.In the complex segmentectomy group, the time of segmental resection with the fluorescence method was significantly shorter than that with the modified inflation-deflation method( P<0.05), and other indexes had no significant difference. Conclusion:Fluorescence method single-port thoracoscopic anatomic segmentectomy has the same perioperative safety and short-term efficacy as modified inflation-deflation method, which can significantly shorten the operative time and improve the operative efficiency in complex anatomic segmentectomy.
