Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective:To explore the effect of the interval of radical prostatectomy after prostate puncture on the perioperative period and prognosis of patients.Methods:Patient’s data from September 2016 to September 2018 whom performed laparoscopic radical prostatectomy at the Affiliated Hospital of Xuzhou Medical University were collected and retrospectively analyzed. All prostate biopsy confirmed prostate cancer and 66 patients underwent laparoscopic radical prostatectomy. The average age was (70.11 ± 5.01) years, ranged from 60 to 79 years. The patients were divided into two groups according to the interval time from prostate biopsy to laparoscopic radical prostatectomy: <7 d group ( n=32) and 6-8 weeks group ( n= 34). The operation time, intraoperative blood loss, postoperative hospital stays, positive rate of incisional margin, postoperative urinary incontinence rate and the rate of urinary incontinence 6 months after operation, rate of postoperative erectile dysfunction and bone metastasis were compared and analyzed between the two groups. When the data conformed to the normal distribution, the data were expressed in Mean±standard deviation ( Mean± SD), and the independent sample t-test was used to evaluate the statistical significance between groups. When the data did not conform to the normal distribution, the measurement data was expressed as Median (interquartile range) [ M( P25, P75)], and the Mann-Whitney U test was used for the comparison between groups. Count data comparison between groups using Chi-square test or Fisher exact probability method. Unconditional multivariate Logistic regression was used to analyze the relationship between outcome and exposure. Results:All the 66 patients successfully underwent surgery, the surgery success rate was 100%. The average operation time of <7 d group and group 6-8 weeks group was [185.00(174.50, 193.50)] min and [183.00(175.00, 187.50) min], respectively, the difference was not statistically significant ( P=0.685 8, U=512.0). The average intraoperative blood loss of group <7 d group and 6-8 weeks group was [185.50(177.75, 205.25)]ml, [189.00(180.75, 206.00)] ml, respectively, the difference was not statistically significant ( P=0.685 9, U=512.0). The average postoperative hospital stays of <7 d group and 6-8 weeks group was [14.00(11.75, 16.00)] d, [13.50(12.00, 15.00)] d, respectively, the difference was not statistically significant ( P=0.785 7, U=522.5). The positive rate of incisal margin of<7 d group and 6-8 weeks group was 18.75%, 14.71%, respectively, the difference was not statistically significant ( P=0.659 5, χ2=0.194). The postoperative urinary incontinence rate of <7 d group and 6-8 weeks group was 6.25% and 8.82%, respectively, the difference was not statistically significant ( P=1.000 0). The urinary control after follow-up for six months of <7 d group and 6-8 weeks group was 6.25% and 2.94%, respectively, the difference was not statistically significant ( P=0.607 7). The postoperative erectile dysfunction rate of<7 d group and group 6-8 weeks group was 9.38% and 8.82%, respectively, the difference was not statistically significant ( P=1.000 0). The postoperative bone metastasis rate of group<7 d and 6-8 weeks group was 6.25% and 5.88%, respectively, the difference was not statistically significant ( P=1.000 0). Conclusions:Performing laparoscopic radical prostatectomy within 7 days following prostate biopsy did not adversely affect the postoperative outcomes and prognosis, also not increased postoperative complications, can shorten the patient′s treatment cycle.

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

Objective To investigate the application efficacy of oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy.Methods From January 2016 to June 2017,180 male patients aged from 60 to 86 years old,whose average age was 71 years old and treated by local anesthesia cystoscopy were collected in this study in the department of Urology of Xuzhou Medical University Affiliated hospital.They were divided into two groups according to the time sequence of visiting doctor.The patients in the research group were treated with oral acetaminophen stapler with compound lidocaine cream and lidocaine injection urethral infusion anesthesia before the examination.The control group was using lidocaine injection urethral infusion anesthesia.To compare the successful rate of operation,operating time and the visual analogue score (VAS) before and after the operation,the patients'limb twist and the tension were observed and recorded.The software of SPSS 16.0 was used for statistical analysis.Results The successful rate of operation in research group and control group was 97.78％ and 91.11％.The VAS score before the operation was (3.2 ± 1.8) and (6.8 ± 2.2).The incidence of complications after treatment was 5.55％ (5/90) and 27.78％ (25/90).The PSS score of 1 h after treatment was (1.1 ± 1.7) and (3.1 ± 1.2).The satisfaction rate was 90.0％ (81/90) and 57.8％(52/90).The differences between the two groups were statistically significant(P ＜ 0.05).However,the opertion time between the two groups was (6.2 ± 1.7) and (6.9 ± 2.1) min.One hour after the opertion,the VAS score was (1.2±0.7) and (1.5±1.1).The score of PSS before the opertionwas (3.4±1.5) and (3.8±1.1).There were no significant differences between the two groups (P ＞ 0.05).Conclusions Taking oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy could obviously reduce urethral pain and the anxiety in the opertion of local anesthesia cystoscopy,which obviously superior to use lidocaine injection urethral infusion anesthesia only.The efficacy and safety were definitely and had got better clinical outcomes.

Objective To investigate the efficacy and safety of intravesical instillation of BCG vaccine in the prevention of early recurrence of middle and high risk non-muscle invasive bladder cancer.Methods From July 2015,patients with non-muscle invasive bladder cancer aged 18-75 years with informed consent were screened and underwent transurethral resection of bladder tumor (TURBT).Immediately intravesical instillation of epirubicin 50 mg was given postoperatively.After pathology was comfirmed,patients was enrolled in group 1 (BCG15) or group 2 (BCG 19) or the control group (epirubicin 18) randomly with SAS 9.3 software.Data of follow-up and Adverse event was collected and analyzed.Results By May 31,2019,531 patients were enrolled in the study.The drop-off rate was 20.1％.167 patients (143 males and 24 females)in group 1,172 patients (141 males and 31 females)in group2 and 84(75 males and 9 females) in the control group with follow-up data were analyzed.There were no significant differences in age,gender,BMI,ECOG score,risk stratification between the three groups (P =0.8641,P =0.2906,P =0.9384,P =0.6126).The median follow-up time makes no statistical difference between the groups (P =0.9251),12.0 (6.0,22.5) months,13.0 (6.0,22.3) months,and 13.0 (7.0,22.3) months.The median recurrence time of the three groups was 4.0 (3.0,6.0) months,4.5 (3.0,9.8) months,4.5 (3.0,8.8) months.There was no statistical difference between the three groups (P =0.2852).Risk stratification in the patients got no significant difference between the three groups (P ＞ 0.05).The 1-year recurrence-free survival rates were 80.0％ in the group 1 and 88.3％ in the group 2 and 73.7％ in the control group.The group 2 was superior to the group 1 and the control group (P =0.0281,P =0.0031).There was no significant difference between group 1 and control group (P =0.2951).There was no significant difference in the cumulative recurrence-free survival between the experimental group 1 and the experimental group 2,(95％ CI 0.80-2.43,P =0.2433).The cumulative recurrence-free survival in the group 1 and the group 2 was better than the control group (95 ％ CI 0.31-0.92,P =0.0266;95 ％ CI 0.20-0.65,P =0.0008).All the cases underwent instillation were analyzed for adverse events.The incidence of overall AE(adverse events) in group 1 was 68.5％ (152/222),the incidence of grade Ⅰ-Ⅱ AE was 53.2％ (118/222),the incidence of grade Ⅲ-Ⅳ AE was 15.3％ (32/222).The incidence of overall AE in the group 2 was 71.8％ (160/223),the incidence of grade Ⅰ-Ⅱ AE was 60.1％ (134/223),and the incidence of grade Ⅲ-Ⅳ AE was 11.7％ (26/223).The overall AE rate in the control group was 53.2％ (59/111),of which the incidence of grade Ⅰ-Ⅱ AE was 42.4％ (47/111),and the incidence of grade Ⅲ-Ⅳ AE was 10.8％ (12/111).There was no difference in the incidence of overall AE between the group 1 and the group 2 (P =0.4497).The incidence of AE in the two experimental groups was higher than that in the control group (P =0.0062,P =0.0008).There was no difference in the incidence of grade Ⅲ-Ⅳ AE between the three groups (P =0.3902).Conclusions BCG(19 instillation schedule) has a better effect on preventing recurrence after 1 year of bladder surgery,which is superior to epirubicin group.The long-term efficacy of BCG in preventing recurrence and the efficacy of different schedules need to be further followed up.The lower urinary tract symptoms,which are mainly urinary frequency,are one of the causes of case fallout and should be fouced in future.Compared with epirubicin,BCG perfusion does not increase the incidence of grade Ⅲ-Ⅳ adverse reactions,and is safe to use.

Objective: To investigate the expression of LIM and SH3 protein 1 (LASP1) in renal cell carcinoma and its significance in the invasion and migration of renal clear cell carcinoma 786-O cell line. Methods: The expression level of LASP1 in 41 cases of renal cell carcinoma tissues and normal renal tissues was analyzed by immunohistochemistry. The relationship between the expression level of LASP1 and clinical characteristics was further analyzed. Expression of LASP1 in 10 cases of tumor tissues with or without lymph node metastasis was analyzed by Western blot. Furthermore, small interfering RNA (siRNA) targeting LASP1 was constructed and transfected into 786-O cells to downregulate LASP1 expression. The interference effect of LASP1 siRNA on LASP1 protein and the expression of related proteins in epithelial mesenchymal transition (EMT) pathway were detected by Western blot. The effects of LASP1 knockdown on cell proliferation, migration and invasion and gene expression were then assessed using CCK8 assay, transwell cell migration system and western blot analysis, respectively. Results: The positive rate of LASP1 expression in renal clear cell carcinoma tissues was 90.2% (37/41), which was significantly higher than that in the adjacent tissues (29.3%, P=0.002). The expression of LASP1 in renal cell carcinoma was positively correlated with lymph node metastasis and TNM stage of renal cell carcinoma (P<0.05). The results of Western blot showed that LASP1 (0.696±0.053) was highly expressed in renal cell carcinoma (1.459±0.628), especially in cases with lymph node metastasis (2.692±0.186, P<0.05). The LASP1 siRNA remarkably down-regulated the expression of LASP1 protein in 786-O cells. The abilities of proliferation, invasion and migration of 786-O cells were decreased significantly in the LASP1 siRNA groups.The relative expression of E-cadherin protein in the siRNA group (0.848±0.020) was significantly higher than those in the siRNA-NC group (0.671±0.018) and control group (0.691±0.037, P<0.05). The relative expression of N-cadherin protein in the siRNA group (0.449±0.047) was significantly lower than those in the siRNA-NC group (0.613±0.018) and control group (0.633±0.045, P<0.05). The relative expression of vimentin protein in the siRNA group (0.477±0.029) was significantly lower than those in the siRNA-NC group (0.598±0.069) and control group (0.633±0.045, P<0.05 for both). Conclusions LASP1 is highly expressed in renal clear cell carcinoma, which is closely related to the development of the cancer. The effects of LASP1 on the invasion and migration of 786-O cells and lymph node metastasis may be related to the EMT.

Objeetive To investigate the effect of TURP on the quality of life of elderly PCa patients with LUTS symptoms.Methods A retrospective analysis of the clinical data from January 2012 to January 2014 of 75 patients admitted to our hospital after prostate puncture biopsy and pathological diagnosis of PCa in elderly patients,mean age (79 ± 7) years old,which 44 cases were associated with different degrees of LUTS symptoms,of which,20 underwent TURP.After the rule of endocrine therapy,we observe and record of patients before and after treatment and 3,12,6 months after the IPSS and QOL score,compared with the changes in the quality of life of patients.Results Forty-four cases of patients with IPSS score in treatment group after 3,6 and December were (6.25 ± 2.53),(5.15 ± 2.25),(5.00 ± 2.36).Compared with the preoperative IPSS basal value (30.55 ± 3.62),the difference was statistically significant (P ＜0.01).However,there was no significant difference in the postoperative patients (P =0.209,0.863,0.154).The QOL score of treatment group after 3,6 and 12 months were (1.35 ± 1.14),(0.85 ± 0.75) and (0.70 ± 0.87).Compared with the preoperative QOL basal value (4.70 ± 0.73),the difference was statistically significant (P ＜ 0.01).However,there was also no significant difference in the postoperative patients (P =0.078,0.023,0.593).Compared with the control group of IPSS and QOL score,there was no significant difference before treatment in the treatment group (F =0.105,P =0.747),however,there was significant difference after treatment(P ＜ 0.01).Conclusions TURP is a safe and effective method to improve the quality of life and improve the quality of life of patients with prostate cancer.

Oncolytic viruses,a novel class of virus vectors,which selectively replicate only in tumor cells,have excellent tumor targeting and good tansfection efficiency.Many oncolytic viruses have apparent curative effect when administered intratumorally.However,the host immune system remains a critical obstacle to systemic administration of virotherapeutics.It appears that cell-based delivery of oncolytic viruses could offer one solution to this critical problem,which provides a new platform to the biological therapy of cancer.

Objective To investigate the expression and significance of Matriptase and HAI-1 protein in prostate cancer (CaP). Methods Specimens of 46 prostate cancers,20 benign prostate hyperplasias (BPH),10 high-grade intraepithelial neoplasias (PIN),and 10 normal prostates (NP) were used. Expressions of Matriptase and HAI-1 proteins in specimens were detected by SP of immunohistochemistry. The results were analyzed in relation to the clinicopathological data. Results The protein levels of Matriptase in CaP tissues were significantly higher than PIN tissues(Z＝-2.150,P＝0.032),and the expression of matriptase in CaP and PIN was higher than that in BPH and NP (Z＝-3.270,P＝0.001;Z＝-2.817,P＝0.005). No statistically significant difference was observed between BPH and NP group (Z＝-0.895,P＝0.325). A progressive increase in the protein levels of Matriptase was observed with increasing tumor grade (rs＝0.583,P＜0.01) and clinical stages（rs＝0.611,P＜0.01）in CaP specimens. The protein levels of HAI-1 in BPH and NP tissues were significantly higher than CaP and PIN tissues（Z＝-3.277,-3.315,P＜0.01）,the levels of HAI-1 in PIN were higher than CaP (Z＝-2.310,P＝0.020). No statistically significant difference was found between BPH and NP (Z＝-0.872,P＝0.330). A progressive decrease in the protein levels of HAI-1 was observed with increasing tumor grades（rs＝-0.634,P＜0.01） and clinical stages（rs＝-0.521,P＜0.01）. The expressions of Matriptase and HAI-1 in CaP tissues showed negative correlations（rs＝-0.712,-0.560,-0.465,respectively,P＜0.01）. Conclusions The abnormal expressions of Matriptase and HAI-1 proteins may be important events during the progression of CaP in humans. Matriptase and HAI-1 Protein may be used as parameters for assessing the malignancy and prognosis of CaP.

ObjectiveTo investigate the inhibitory effects and related toxicity of all-trans-retinoic acid(ATRA) combined with arsenic trioxide(As2O3) on transplanted human bladder neoplasms in nude mice.MethodsThe subcutaneously transplanted tumor models of human bladder neoplasms in nude mice were established and then it was randomly divided into four teams: Saline group, ATRA group, As2 O3 group and the combination of ATRA and As2 O3 group.Each group composed of 10 nude mice and received intratumor injection in the following 14 d.The tumor growth inhibitory rate was calculated.The pathological changes of tumor,cardiac, liver, and kidney were observed after H.E.staining.The expression of MVD (Marked with CD43) and VEGF were detected by SP of immunohistochemistry.Blood routine examination and hepatic and nephritic functional examination was carried out to evaluate the side-effects.Results The tumor growth was significantly suppressed in ATRA group(inhibitory rate was 41.82％) and As2O3 group (inhibitory rate was 43.77％) compared with saline group.When ATRA combined with As2O3 ,inhibitory effects were improved(inhibitory rate was 68.55％).The difference of growth inhibitory rate between each group was obviously significant(x2 =26.81, P ＜0.01).There was less expression of MVD (Marked with CD43) and VEGF in ATRA group and As2 O3 group and the combination group compared with saline group (ODVEGF = 19.23 + 2.32,20.72 + 2.01,17.16 ± 1.59,27.33 ± 2.17, respectively; ODMVD = 44.77 + 8.25,43.39 + 7.41, 30.56 + 7.71,141.12 + 8.38, respectively), and the suppressed effect in the combination group was most significant (t = 3.16,3.08,3.37, P ＜ 0.01).WBC inhibition was seen in ATRA group and As2O3 group and the combination group, but no significantly difference among them(P ＞0.05).Hepatic and nephritic toxicity were not found.ConclusionsCombination of ATRA and .As2O3 had obvious synergistic effects on transplantéd tumor of human bladder neoplasm in nude mice, and moderate white blood cell inhibition and no hepatic or nephritic toxicity.
