Objective To detect the expression of costimulatory molecules B7-H4 and programmed death ligand 1 (PD-L1) in bladder cancer,and to explore the correlation between them and clinicopathological features of bladder cancer.Methods Immunohistochemical staining was used to detect the expression of B7-H4 and PD-L1 in 98 cases of bladder urothelial carcinoma,which were confirmed by pathology from August 2014 to December 2015 in our hospital.There were 23 females,aged 45-82 years,with an average age of 67.8 years.Among them,42 cases of adjacent normal tissues were used as controls.The clinical stage,histological grade and recurrence of bladder cancer were collected,and the correlation between them was analyzed.Results The positive rates of B7-H4 and PD-L1 in bladder urothelial carcinoma were 54.1％ (53/98) and 59.2％ (58/98),respectively,and there was no expression in normal bladder tissues (P ＜ 0.05).The positive expression rate of B7-H4 in muscle invasive bladder cancer (MIBC) patients was higher than that in non-muscle invasive bladder cancer (NMIBC) [73.5％ (25/34) vs.43.8％ (28/64),P =0.005].The positive expression rate of B7-H4 in high-grade patients was higher than that of low-grade [70.0％ (21/30) vs.47.1％ (32/68),P =0.036].The expression rate of B7-H4 in high-risk group was higher than that of low-intermediate risk group [57.1％ (20/35) vs.27.6％ (8/29),P =0.018].The positive expression rate of PD-L1 in patients with MIBC was higher than that in NMIBC [79.4％ (27/34) vs.48.4％ (31/64),P =0.003].The PD-L1 expression rate of histological high-level group was higher than that of low-level group [73.3％ (22/30) vs.52.9％ (36/68)],but the difference was not statistically significant (P =0.058).The PD-L1 expression rate in high-risk group was 68.6％ (24/35),and also higher than low-middle group 24.1％ (7/29) (P ＜ 0.05).There was a positive correlation between the expression of B7-H4 and PD-L1 in bladder urothelial carcinoma (r =0.318,P=0.002).The combined recurrence rate of the two groups was significantly higher than that of the negative expression of the two groups [66.7％ (14/21) vs.30.8％ (8/26),P=0.014].Conclusions The expression of B7-H4 and PD-L1 is up-regulated in bladder urothelial carcinoma,which is closely related to the clinical stage,histological grade,risk classification and recurrence of NMIBC.

OBJECTIVETo evaluate surgical outcomes and the feasibility of robotic thyroidectomy and central neck dissection (CND).

METHODSThe clinical data of 40 patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND using the Da Vinci system through axillo-bilateral-breast approach in Jinan Military General Hospital of People's Liberation Army from February to December 2014 were analyzed retrospectively (robotic group). Other forty patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND by open approach were selected as the control (open group). Cosmetic satisfaction was assessed after a month postoperation by the numerical score system. t-test and χ(2) test were used to compare the clinical characters, total operative time, intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, visual analogue scale for pain, postoperative complications, and cosmetic effect between the 2 groups.

RESULTSAll 80 patients were diagnosed of papillary thyroid microcarcinoma. The total thyroidectomy (or lobectomy/isthmusectomy) with CND of 40 patients were successfully performed by da Vinci Si surgical system. The numbers of total thyroidectomy of robotic group and the open group were 36 and 37, respectively. The numbers of metastatic lymph nodes of robotic group and open group were 14 and 15, respectively. The operation time of the robotic group was (130±12) minutes, which was longer than that of open group (98±11) minutes (t=12.432, P<0.05). The study showed statistical significant difference between the two groups regarding the visual analog scale pain assessment (1.9±0.9 vs.3.9±1.1, t=8.900, P<0.05). There were no statistical significant difference of intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, and the complication rate between the 2 groups.Postoperative cosmetic result was more satisfying on the robotic group (9.1±0.5) than open group (4.8±1.5) (t=17.200, P<0.05).

CONCLUSIONSThe robotic total thyroidectomy (or lobectomy and isthmusectomy) and CND has similar surgery safety and feasibility as open procedures. The robotic thyroidectomy is a good alternative surgical modality for patients with papillary thyroid microcarcinoma who wish to avoid neck scars.

Objective:To explore the role of Mycoplasma pneumoniae (MP) in hospitalized children with community-acquired pneumonia (CAP) in Suzhou.Methods:Pathogen data of 2 367 patients with bronchiolitis, bronchopneumonia, lobar pneumonia, and interstitial pneumonia were retrospectively analyzed from January 2017 to December 2018 in Children′s Hospital of Soochow University. The detected pathogens were MP, respiratory syncytial virus (RSV), adenovirus (Adv), influenza A, B, parainfluenza virus (PIV) 1, 2 and 3, human metapneumovirus (hMPV), boca virus (HBoV) and bacteria.Results:The most common pathogen of bronchiolitis was RSV (34.9%, 249/713), followed by MP (15.8%, 113/713) and hMPV (11.4%, 85/713). The most common pathogen of bronchial pneumonia was Streptococcus pneumoniae (Sp, 14.8%, 180/1 220), followed by RSV (13.1%, 160/1 220) and MP (10.2%, 124/1 220). The most common pathogen of lobar pneumonia was MP (47.8%, 141/295), followed by Sp(12.9%, 38/295). The most common pathogen of interstitial pneumonia was MP (35.3%, 49/139), followed by RSV (23.0%, 32/139) and Adv (6.5%, 9/139). Compared with non-MP infections, children with MP infections were older, and had higher percentage of fever and less shortness of breath. The adjusted OR(95% CI) was 2.4 (1.1-3.5), 5.1 (3.2-10.4) and 0.2 (0.0-0.4), respectively. Conclusions:MP is the most common pathogen of lobar pneumonia and interstitial pneumonia and the second most common cause of bronchiolitis. MP infections are usually associated with older age, higher percentage of fever and less shortness of breath.

ObjectiveTo understand the protective effect of pentavalent rotavirus （RV） vaccine in preventing infectious diarrhea among infants and young children， and to provide a basis for formulating prevention and control strategies for this population. MethodsA retrospective cohort study was conducted to follow up resident children born in Pinghu City from January 2019 to June 2021 for two years. Data on morbidity and pentavalent RV vaccine inoculation were collected to analyze the incidence density of rotavirus infection among children inoculated with different doses of the pentavalent RV vaccine， and to calculate the vaccine protection rate. ResultsA total of 5 141 resident children were surveyed， with a RV vaccination rate of 31.63% and a full vaccination rate of 30.83%. There were 154 cases of RV infection， with an incidence density of 1 392.69/100 000 person-years. Among the 875 migrant children （17.02%）， the full vaccination rate was 20.46%， while among the 4 266 local children （82.98%）， the full vaccination rate was 32.96%. The difference in full vaccination rate between migrant children and local children was statistically significant （χ²=53.209， P<0.001）. The proportions of boys and girls were 51.94% and 48.06%， respectively， with a full vaccination rate of 29.74% and 32.01%， respectively； and the difference was not statistically significant （χ²=3.111， P=0.078）. The proportions of children with normal birth weight and abnormal birth weight were 91.56% and 8.44%， respectively， with a full vaccination rate of 31.82% and 20.05%， respectingly； and the difference was statistically significant （χ²=25.852， P<0.001）. Among the 3 515 children who were not vaccinated with the pentavalent RV vaccine， 118 of which were infected， with an incidence density of 1 503.32/100 000 person-years （with an incidence rate of 3.36%）. Among the 41 children who were partially vaccinated （received only 1-2 doses）， the incidence density was 1 058.54/100 000 person-years （with an incidence rate of 2.44%）. Among the 1 585 fully vaccinated children， 35 of which were infected， with an incidence density of 1 123.96/100 000 person-years （with an incidence rate of 2.21%）； and the difference in incidence rate was statistically significant （χ²=4.988， P=0.026）. The protection rate for partial vaccination was 28.00% （95%CI：22.00%‒33.50%）， while for full vaccination was 35.10% （95%CI： 29.80%‒40.00%）. ConclusionPentavalent RV vaccination can effectively prevent rotavirus infection in infants and young children， in which the full vaccination is more effective than partial vaccination. It is recommended to strengthen the monitoring of circulating RV strains in the city， develop more targeted vaccines， and increase the RV vaccine coverage rate and full vaccination rate among infants and young children through the expansion of the national immunization program and enhancement of public education， so as to effectively reduce the incidence of infectious diarrhea in infants and young children.

Objective:To investigate the current situation of medical social worker supervision in Shanghai, for reference to promote the high-quality development of medical social work.Methods:From June to July 2022, a questionnaire survey was conducted on the in-service medical social workers in all medical institutions with medical social work departments or posts in Shanghai. The questionnaire mainly included demographic information, current status of supervision implementation, and effectiveness of supervision. The data were analyzed descriptively with t test for comparison between groups and the Pearson test was for correlation analysis. Results:A total of 99 medical social workers were included in this study, 65 had received supervision, and medical institutions where 58 people located had established the supervision system. The average scores of actual and expected supervisory support received by medical social workers were 3.71 and 4.20 respectively, and the mean burnout level score was 32.91. The effect of establishing a supervision institutions on burnout was statistically significant ( P<0.05) and actual access to supervision support was negatively associated with burnout ( P<0.05). Conclusions:The overall situation of medical social work supervision in Shanghai was positive, but the demand for supervision was not fully satisfied; Supervision had a positive impact on reducing the burnout level. It is suggested that medical social work should further strengthen the cultivation of supervisory talents, promote the construction of supervisory systems, and improve the quality of supervision.
