Objective To evaluate the outcome of the laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy. Then define the characteristics of the learning curve of this procedure. Methods A prospectively collected database comprising all medical records of the first 79 consecutive patients underwent laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy performed by one surgeon was studied. The patients were divided into seven groups (13 cases in last group) by operative sequence. Data on patients' demographics, clinical and outcome variables including operative duration, conversion to open surgery, complications, and length of hospital stay were analyzed. The learning curve for the laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy was established through the moving average and ANOVA methods. Results Comparing the early with the late experiences (33 v. 46 cases), the surgeon-specific outcomes significantly improved in terms of operating times [(292.7 ± 29.8) vs (215.3 ± 10.2) min, P < 0.05], There was four patients converted to open surgery in the early of experiences.the late experiences was five case, it was no statistical significance. significant differences were not shown in the hospitalization period and infectivity complications. Conclusion Operative duration can be reduced with increasing experience of laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy, In this study, the learning curve for a laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy was about thirty-three cases.

OBJECTIVETo investigate the effect of the combination therapy of biofeedback with electrical stimulation on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) through clinical trials.

METHODSA total of 140 cases of diagnosed CP/CPPS were randomly divided into a control group (n = 20), a biofeedback group (BF, n = 40), an electrical stimulation group (ES, n = 40), and a biofeedback plus electrical stimulation group (BF + ES, n = 40). The latter three groups were treated by corresponding methods 5 times a week for 2 weeks, while the controls left untreated. After the treatment, all the patients were followed up for 30 days. The NIH chronic prostatitis symptom index (NIH-CPSI) scores and the results of uroflowmetry were obtained and compared before and after the treatment.

RESULTSCompared with the control group, the scores on pain, urinary symptoms and quality of life (QOL) and the total NIH-CPSI scores were obviously decreased (P < 0.05), and the maximum flow rate (MFR) markedly improved (P < 0.05) in the BF, ES and BF + ES groups after the treatment, with significant differences between the former two and the latter one (P < 0.05), but not between the BF and ES groups (P > 0.05), nor in the control group before and after the treatment (P > 0.05).

CONCLUSIONThe combination therapy of biofeedback with electrical stimulation has a synergistic effect on CP/CPPS by alleviating pain and urinary symptoms, improving QOL and elevating MFR.

Ultrafine powder and cell wall-broken powder of herbal medicine lack of the morphological characters and microscopic identification features. This makes it hard to identify herb's authenticity with traditional methods. We tested ITS2 sequence as DNA barcode in identification of herbal medicine in ultrafine powder and cell wall-broken powder in this study. We extracted genomic DNAs of 93 samples of 31 representative herbal medicines (28 species), which include whole plant, roots and bulbs, stems, leaves, flowers, fruits and seeds. The ITS2 sequences were amplified and sequenced bidirectionally. The ITS2 sequences were identified using Basic Local Alignment Search Tool (BLAST) method in the GenBank database and DNA barcoding system to identify the herbal medicine. The genetic distance was analyzed using the Kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic tree was constructed using MEGA 6.0. The results showed that DNA can be extracted successfully from 93 samples and high quality ITS2 sequences can be amplified. All 31 herbal medicines can get correct identification via BLAST method. The ITS2 sequences of raw material medicines, ultrafine powder and cell wall-broken powder have same sequence in 26 herbal medicines, while the ITS2 sequences in other 5 herbal medicines exhibited variation. The maximum intraspecific genetic-distances of each species were all less than the minimum interspecific genetic distances. ITS2 sequences of each species are all converged to their standard DNA barcodes using NJ method. Therefore, using ITS2 barcode can accurately and effectively distinguish ultrafine powder and cell wall-broken powder of herbal medicine. It provides a new molecular method to identify ultrafine powder and cell wall-broken powder of herbal medicine in the quality control and market supervision.

Objective: The current study was designed to evaluate the clinical application of radioimmunoimaging(RII) for lymph node metastasis in esophageal carcinoma. Methods:1)131I was used to label McAb G9(specific to cellular membrane antigen of human esophageal carcinoma) and form labeling compound 131I-G9. Administration of 131I-G9 in esophagus submucosally with a specific injector for the purpose of submucosal injection via endoscopies in preoperative patients with squamous cell carcinoma of thoracic esophagus followed by RII. 2)The samples of dissected lymph node were used for detection of radioactivity. Results: 1)The pictures at 48 h showed that small radioactivity concentrated dots appeared dispersedly in mediastinum and upper abdomen around esophagus and cardiac gastric. The lymph nodes were considered metastatic in above regions. 2)The pathological results of the lymph nodes dissected compared to the RII result. The metastatic lymph nodes were found in the regions of dispersedly concentrated radioactivity, while no metastatic lymph nodes could be found in the radioactivity free regions. 3)After counting for radioactivity, lymph node metastases showed higher antibody uptake than the non-metastases lymph nodes. The difference was statistically significant. Conclusion: 131I-G9 may be used to locate metastatic lymph nodes in patients with esophageal carcinoma.

Objective To investigate the effect of inhaled corticosteroids(ICS)on adverse outcomes in chronic obstructive pulmonary disease(COPD)(COPD-CAP)patients with community-acquired pneumonia(CAP).Methods The clinical data of COPD-CAP patients who visited the respiratory department of respiratory of Wenzhou Integrated Traditional Chinese and Western Medicine Hospital from January 2021 to January 2023 was retrosspective collected.They were divided into an ICS group and a non ICS group based on whether they were eligible for ICS treatment.A univariate analysis was used to compare the differences in general data,imaging outcomes(multilobed infiltration and pleural effusion),and clinical outcomes(non-invasive mechanical ventilation,invasive mechanical ventilation,ICU admission,and 30-day mortality)between two groups.The Logistic regression was used to explore the relationship between ICS and imaging and clinical outcomes.Result A total of 120 COPD patients were included in this study,including 38 in the ICS group,62 in the non ICS group.The univariate results showed that COPD-CAP patients in the ICS group had lower GOLD scores,PSI scores,and CURB-65 scores(P＜0.05).The multivariate Logistic regression showed that the use of ICS reduces the risk of multi leaf infiltration[OR=0.291,95％CI(0.123,0.687),P=0.005],pleural effusion[OR=0.309,95％CI(0.105,0.908),P=0.033],non-invasive mechanical ventilation[OR=0.040,95％CI(0.012,0.129),P＜0.001],invasive mechanical ventilation[OR=0.099,95％CI(0.013,0.783),P=0.028],ICU occupancy[OR=0.207,95％CI(0.056,0.762),P=0.018],and 30-day mortality[OR=0.179,95％CI(0.039,0.822),P=0.027].Conclusion ICS reduces the risk of multilobed infiltration,pleural effusion,mechanical ventilation usage,ICU occupancy,and 30-day mortality in COPD patients admitted to CAP.

Objective To mvesugate the Tate of YMDD mutation accompamed with pre-core(region and core promotor region mutation and the clinical significance.Methods YMDD mutation and pre-core(at 1896 nu- cleotide)region and core promotor region(at 1762.1764 nucleotide)mutation were detected from the 122 patients with chronic hepatitis B virus after receiving lamivudine treatment above 6 months.Results 40 cases were tested for YMDI)mutations in 122 HBV patients with lamivudine treatment,and the positive rate of YMDD mutation was 32.8 %.After YMDD mutation,ALT,AST and HBV DNA of the patients significantly increased(P0.05).Conclusion The patients with YMDD mutation had higher rate of pre-core region(at 1896 nucleotide)and basal core promotor region(at 1762, 1764 nucleotide)mutation than those without YMDD mutation,but there was no correlation between the mutation and the deterioration of disease condition and the bad prognosis.

OBJECTIVETo evaluate the effects of urinary kallidinogenase on subarachnoid hemorrhage (SAH) in rabbits.

METHODSRabbits symptomatic cerebral vasospasm model was built though Endo method, among the 40 rabbits, 8 died or had severe nervous system syndrome, the other 32 were randomly divided into 4 groups:group A, control group, injection of normal saline to the cisterna magna;group B, subarachnoid hemorrhage;group C, injection of human urinary tissue kallikreins;group D, treated with Nimodipine. The behavior scores, neurological scores and cerebral angiography changes were observed.

RESULTSFood intake obviously decreased and neurological deficit were seen in group B, while which were attenuated in group C and group D, and group A was normal. Comparing the diameter of basilar artery was (1.9 +/- 0.3) mm before SAH, the diameter of group B 4 d later was (1.5 +/- 0.3) mm, 7 d later (1.4 +/- 0.3) mm, the difference was significant (P < 0.05). Comparing with group C on the day 4th and 7th, the diameters of basilar artery were significantly different (P < 0.001). Comparing with group D on the day 4th, 7th and 14th, there was no obvious improvement.

CONCLUSIONUrinary kallidinogenase and Nimodipine can obviously alleviate symptomatic cerebral vasospasm in rabbits remarkably, but the former's effect of attenuating vasospasm is better than that of Nimodipine.
