Objective To investigate the morphologic abnormalities of myenteric plexus in diabetic rats and to explore the mechanism of its effect on gastrointestinal motility.Methods Thirty rats were randomly divided into diabetic group and control group.Gastrointestinal transit time was measured and histologic changes of cholinergic and nitriergic nerves in ileum myenteric plexus were observed with enzy- matic histochemistry.Results Four months after the establishment of the diabetic rats model,gastroin- testinal transit time was found delayed comparing with control group,the density of cholinergic neurons in the ileum myenteric plexus was decreased (P＜0.01) and the densities of nitriergic ganglions and neurons were significantly increased comparing with control group (P＜0.05 and P＜0.01).Conclu- sion Decrease of cholinergic nerves and increase of nitriergic nerves in the myenteric plexus of intestine is one of the mechanisms of delay gastrointestinal transit time in diabetic rats.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

Objective:To investigate the efficacy and safety of a treatment regimen based on daratumumab in patients with high-risk relapsed refractory multiple myeloma(MM)with mSMART 3.0 score.Methods:Clinical data were collected from 16 patients with mSMART3.0 score high-risk relapsed refractory MM treated at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from May 2020 to May 2023,all of whom received daltezumab-based regimen(regimen drugs including dexamethasone,isazomib,bortezomib,lenalidomide).The efficacy and safety of the treatment were retrospectively analyzed.Results:The median age of 16 patients was 63.5(47-70)years old,including 10 cases of IgG type,2 cases of IgA type,and 4 cases of light chain type.The curative efficacy was judged in all 16 patients,with an overall response rate of 93.75％(15/16),including 4 cases of strict complete remission(sCR),1 case of complete remission(CR),2 case of very good partial remission(VGPR),partial remission(PR)in 5 cases,and minor remission(MR)in 3 cases.The median follow-up time was 11(2-30)months,and the median progression-free survival and median overall survival were not achieved in 16 patients at the median follow-up period.The hematologic adverse effects of the treatment regimen using daratumumab-based were mainly neutropenia,and the non-hematologic adverse effects were mainly infusion-related adverse reactions and infections.Conclusion:Daratumumab-based regimen for the treatment of relapsed refractory MM patients with high risk of mSMART3.0 score has better efficacy and safety.

OBJECTIVEThe present study was designed to explore the practical application of the rapid etiological diagnosis by detecting specific IgM antibody against common respiratory viruses in children with acute lower respiratory infections (ALRI).

METHODClinical specimens including nasopharyngeal aspirates and serum of acute phase from hospitalized children were collected from 207 infants and children with acute lower respiratory infections from March 2009 to September 2010. Seven common respiratory virus antigens were identified from the collected nasopharyngeal aspirates by direct immunofluorescence assay (DFA). ELISA was used to detect specific IgM antibody against RSV, ADV, IFVA, IFVB and PIV, while indirect immunofluorescence assay (IFA) was used to detect specific IgM antibody against RSV, ADV, IFVA, IFVB, PIV1, PIV2 and PIV3 in collected acute phase serum.

RESULTThe overall positive rates to detect viral antigen by using DFA, ELISA and IFA was 67.6%, 57.5% and 39.6%, respectively. The consistent rate of ELISA and IFA versus accepted DFA were 21.7% and 31.4%, respectively. The average days from onset of the symptoms to blood sample collection for those with the consistent results by ELISA and DFA were 12.0 d for ADV, 9.6 d for PIV2, 9.5 d for IFV, and 5.3 d for RSV, respectively, and by IFA and DFA were 15.0 d for PIV3, 9.2 d for ADV, and 7.4 d for RSV, respectively. Among all age groups, the consistent rate of serum viral IgM and antigen detections was highest in children younger than 3 years old.

CONCLUSIONAlthough there were differences between serum IgM antibody and viral antigen detections, specific IgM antibody detection was of value in early and rapid etiological diagnosis of pediatric ALRI, especially for young children. It could provide serologic evidence of respiratory virus infection. The diagnostic rate of pathogen could be improved if it was used in combination with viral antigen diagnostic methods.

OBJECTIVETo explore the efficacy and safety of endoscopic submucosal enucleation (ESE) for gastric submucosal tumors (SMTs) originated from muscularis propria.

METHODSA total of 116 patients with gastric SMT originated from muscularis propria underwent ESE in Department of Gastroenterology of the Taizhou Hospital between July 2006 and March 2011. The occurrence of intra-operative and post-operative complications and corresponding treatment were recorded. After the treatment of ESE, the patients were followed up endoscopically.

RESULTSThe success rate of operation was 96.6%. The mean time of the procedure was (51.9±16.3) min. Complications included intra-operative bleeding (n=9, 7.8%), perforation (n=20, 17.2%), and post-operative bleeding (n=3, 2.6%). Among them, 5 cases (4.3%) required surgical intervention. None of patient had other complications such as peritoneal abscess or peritonitis. The mean hospitalization time after ESE was 6.1 days. The median follow-up period was 12 months (range, 3-48 months) and there was no residual tumor or recurrence.

CONCLUSIONESE is a safe and feasible treatment for patients with gastric SMT originated from muscularis propria.

BACKGROUNDTransurethral resection of prostate (TURP) has been widely used as a golden standard therapy of benign prostatic hyperplasia for over 40 years. However, not all patients achieved favorable outcome postoperatively. Since the level of bladder outlet obstruction and the dysfunction of detrusor (overactive and underactive) were both found to affect surgical efficacy, urodynamics was recommended as routine preoperative examination in selecting proper surgical candidates by International Continence Society in spite of its invasiveness and high cost. The aim of this research was to compare the predictive value between ultrasonography and urodynamics for TURP efficacy and determine if preoperative urodynamic test could be replaced by ultrasonography.

METHODSTwo hundred and seventy-one patients took part in the retrospective analysis. All the subjects had preoperative evaluation of symptoms, life quality, and combined examination of ultrasonography and urodynamics. Surgical efficacy was measured according to the recovery of international prostate symptom score, quality of life score, and maximal flow rate 6 months after TURP. Fisher's linear discriminant analysis was applied to establish the predictive models of surgical efficacy by choosing parameters from ultrasonography or urodynamics as independent factors. Receiver's operating characteristic curve was then plotted to compare the values between the models.

RESULTSSensitivity, specificity, positive and negative predictive value of models consisting of parameters from both ultrasonography and urodynamics were favorable. Corresponding models of ultrasonography and urodynamics were found to have non-significant difference in area under curve (P > 0.05).

CONCLUSIONSPreoperative ultrasonography has as strong value as urodynamics does in predicting surgical outcome of patients undergone TURP and might take the place of urodynamics in selecting surgical candidates. Further prospective analysis with larger popularity and longer period of follow up should be launched to verify the result of this research.
