Objective:To investigate the effect of lymphovascular invasion (LVI) on biochemical recurrence in patients treated with radical prostatectomy (RP).Methods:From June 2012 to November 2020, 403 cases treated with RP in the Second Hospital of Tianjin Medical University were analyzed retrospectively. Median age was 67 (range 47-81) years old. Median prostate specific antigen (PSA) was 18.0 (range 1.9-813.0) ng/ml. All patients received prostate biopsy and were confirmed with prostatic acinar adenocarcinoma according to pathology. The Gleason score of 44 (10.9%) cases were 6, 65 (16.1%) cases were 3+ 4, 62 (15.4%) cases were 4+ 3, and 232 (57.5%) cases were ≥8. 73 (18.1%) patients received neoadjuvant hormonal therapy. RP and pelvic lymph node dissection were carried out in all patients including 10 open surgery, 144 laparoscopic surgery and 249 robot-assisted laparoscopic surgery. The χ 2 test was used to analyze the correlation between LVI and clinicopathological characteristics. Kaplan-Meier method and log-rank test were used to summarize time-to-biochemical recurrence end point and compare biochemical recurrence-free survival between LVI positive and negative groups. Univariable and multivariable analyses were performed to test the possible factors of biochemical recurrence with Cox proportional-hazard model. Results:Of all 403 patients treated with RP, the final Gleason score of 68 (16.9%) cases were≤6, 87 (21.6%) cases were 3+ 4, 89 (22.1%) cases were 4+ 3, and 159 (39.5%) cases were≥8. 179 (44.4%) patients had positive surgical margins. The rate of seminal vesicle invasion was 23.6% (95 patients). There were 167 (41.4%) cases with T 1~2 and 236 (58.6%) cases with T 3~4 pathological stage. 39 (9.7%) patients had lymph node metastasis. 62 (15.4%) patients were LVI positive and 341 (84.6%) patients were LVI negative. There were statistically significant differences in biopsy and final Gleason score, pathological stage, rates of seminal vesicle invasion and rates of positive lymph node between LVI positive and negative patients ( P<0.05). 259 (64.3%) patients received adjuvant hormonal therapy and 70 (17.4%) patients received adjuvant hormonal plus radiation therapy. Median follow-up time was 22 (range 6-89) months. 23 (37.1%) occurred biochemical recurrence in LVI positive cases and median biochemical recurrence-free survival was 41 months. Meanwhile, 71 (20.8%) occurred biochemical recurrence in LVI negative cases and median biochemical recurrence-free survival was not reached, significantly longer than LVI positive cases ( P<0.001). Multivariable analysis showed that PSA level, biopsy gleason score, neoadjuvant hormonal therapy, pathological stage, positive surgical margins, seminal vesicle invasion, lymph node metastasis and LVI were significantly associated with prognostic prediction of biochemical recurrence. Conclusions:LVI implies shorter biochemical recurrence-free survival and could be an independent predictor on biochemical recurrence in patients treated with RP.

Objective: To explore the current status related to behavioral problems among children and adolescents aged 12-16 years old in Guizhou Province, China, and to provide a reference for timely prevention and intervention measures. Methods: To capture different economic development levels, a multistage stratified cluster sampling method was used. A total of 3 217 children and adolescents aged 12-16 years old from six middle schools and six primary schools in Guiyang, Duyun, Kaili City from Guizhou Province participated in this study. The Achenbach Child Behavior Checklist (CBCL) and a self designed questionnaire were administered between August and December 2021. Results: The overall detection rate of behavioral problems among the students was 16.60% , and the rate was 14.41% and 18.62% among male and female students, respectively. The results of the Logistic regression analysis showed that good peer relationships ( OR=0.25, 0.16, P <0.05) were associated with a lower risk of behavioral problems in children and adolescents. However, the following factors were associated with an elevated risk of behavioral problems: nonparents as the main caregivers( OR = 1.44 ); children s daily screen time was 1-2 h ( OR =1.47) or more than 2 h( OR =2.75); children who had no sports hobbies( OR = 1.36); father parenting for doting or neglect( OR =1.85, 2.01); maternal parenting for doting( OR = 2.12 ); father had bad life habits( OR =1.69); father and mother were occasionally sick( OR =1.30, 1.38)( P <0.05). Conclusion Behavioral problems among children and adolescents in Guizhou Province is related to children s unhealthy living habits and various factors in the family environment. It is suggested that families, schools and relevant functional departments give full play to their own advantages and take comprehensive measures to prevent the occurrence of behavioral problems among children and adolescents.

Objective:To evaluate the efficacy and safety of docetaxel plus hormone therapy in metastatic prostate cancer.Methods:From April 2016 to April 2019, 204 cases with bone metastatic prostate cancer in the Second Hospital of Tianjin Medical University were analyzed retrospectively. There were 97 patients responded to hormone therapy including 92 cases with high-burden metastasis (more than 4 bone metastases with one or more beyond the axial skeleton) and 5 cases with low-burden metastasis, with average age of 70 years (range 42-87 years) and median prostate specific antigen (PSA) of 74.1 ng/ml (range 11.0-145.0 ng/ml). Among them, there were 35 patients (36.1%) with a Gleason score of 7 or lower, and 62 patients (63.9%) with a Gleason score of 8 or higher. There were 26 patients suffering from bone pain, with average numerical rating scales(NRS) score of 3.7. In addition, there were 107 patients being resistant to hormone therapy, with average age of 73 years (range 56-83 years), and median PSA of 84.5 ng/ml (range 12.4-490.2 ng/ml), including 32 patients (29.9%) with a Gleason score of 7 or lower, and 75 patients (70.1%) with a Gleason score of 8 or higher. Among them, there were 75 patients suffering from bone pain, with average NRS score of 5.4. All patients received continuous hormone therapy combined with docetaxel (at a dose of 75 mg per square meter of body-surface area every 3w, plus prednisone 5 mg twice a day), and PSA progression-free survival (PSA-PFS), NRS score, pain relief, and adverse events were analyzed. Additional analysis of the correlation between PSA-PFS and subgroups with age, PSA level and Gleason score were performed.Results:For patients with metastatic hormone sensitive prostate cancer (mHSPC), 6 (6.2%) cases only received 1-2 cycles of chemotherapy due to different reasons, and the others received 3-6 cycles(average 4.7)with the median follow-up of 15 months. Of patients who received ≥3 cycles, there were 36 cases presenting PSA progression, with the median PSA-PFS of 22 months, average NRS score decline from 3.9 to 3.0, and pain relief rate of 72.0%(18/25). For patients with metastatic castration-resistant prostate cancer (mCRPC), 9 (8.4%)cases only received 1-2 cycles of chemotherapy, and the others received 3-14 cycles (average 5.6). Of patients who received≥3 cycles, there were 51 cases with PSA progression, with the median PSA-PFS of 11 months, average NRS score decline from 5.6 to 4.4, and pain relief rate of 48.6%(35/72). Subgroup analysis showed a significant correlation between PSA level and PSA-PFS for patients with mCRPC( P=0.026). Age or Gleason score was not significantly correlated to PSA-PFS in mHSPC or mCRPC( P>0.05). For patients with mHSPC, grade 3 or 4 neutropenia occurred in 17 cases(17.5%), nausea and vomiting in 27 cases(27.8%), and fatigue in 25 cases(25.8%). For patients with mCRPC, grade 3 or 4 neutropenia occurred in 24 cases (22.4%), nausea and vomiting in 34 cases(31.8%), and fatigue in 26 cases(24.3%). Allergic reaction and sensory neuropathy toxicity were occasional. Conclusion:Efficacy of docetaxel plus hormone therapy was confirmed in metastatic prostate cancer and adverse events were tolerable.

OBJECTIVE：To explo re the dose-effect relationship and mechanism of protective effects of total asiaticoside （TA） on gastrointestinal motility and enteric nervous system （ENS）in aged functional dyspepsia （FD）model rats. METHODS ：Aged male SD rats of 16 months old were randomly divided into blank control group ，model group ，TA low dose ，medium dose and high dose groups （15，30，60 mg/kg），with 8 rats in each group. FD model was established by tail-stimulation combined with irregular diet for 4 weeks. The next day after modeling ，administration groups were given relevant doses of TA solution intragastrically ； control group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 15 d. Gastric emptying rate and small intestinal propulsion rate of rats were examined. ELISA were used to detect serum contents of MTL and VIP. Immunofluorescence and immunohistochemistry were proposed to measure the expression of ENS marker （S100β and GDNF）in gastric antrum tissue. The protein expression of S 100β，GFAP，PGP9.5，GDNF，p-MEK and p-ERK 1/2 in gastric antrum tissue were measured by Western blotting assay. RESULTS ：Compared with blank control group ，gastric emptying rate and small intestinal propulsion rate ，serum MTL content and protein expression of PGP 9.5 in gastric antrum tissue of model and TA low，medium dose group were decreased significantly ，while serum VIP content ，protein expressions of S 100β，GFAP，GDNF， p-MEK and p-ERK 1/2 in gastric tissue were increased significantly （P＜0.05）. Compared with model group ，gastric emptying rate and small intestinal propulsion rate of TA groups were increased significantly （P＜0.05）；except for GFAP protein in TA low dose group（P＞0.05），the serum MTL content and the expression of PGP 9.5 protein in gastric antrum tissue of rats in TA groups were increased significantly ，while serum VIP content ，protein expression of S 100β，GFAP，GDNF，p-MEK and p-ERK 1/2 in gastric antrum tissue were decreased significantly （P＜0.05）. Some or most of the content of gastrointestinal motility indexes and related factor protein expression were significantly different among TA groups （P＜0.05），and the indexes in TA high dose group could recover to the levels which were not significantly different with blank control group （P＞0.05）. CONCLUSIONS ：TA can dose-dependently improve the gastrointestinal motility deficiency and ENS dysfunction in aged FD model rats ，especially in high dose（60 mg/kg）of TA group. Its mechanism may be related with promoting the release of endogenous MTL ，inhibiting the secretion of VIP ，expression of GDNF and the activation of downstream signaling pathway ，and promoting the repair of ENS and intestinal neurons.
