For muscle-invasive bladder cancer (MIBC) patients, preoperative neoadjuvant chemotherapy (NAC) can reduce the tumor stage, treat micrometastases, prolong the median survival, and improve the prognosis.However, NAC is associated with side effects such as renal impairment, thromboembolism and drug toxicity.NAC itself suffers from deficiencies such as renal function impairment, thromboembolism, and drug toxicity.Its therapeutic efficacy is affected by factors such as tumor pathology type, DNA repair gene defects, whether it is primary MIBC, and TNM staging, so there are certain limitations in its use.Based on the cisplatin treatment regimen, more and more studies are exploring the limitations and shortcomings of NAC in MIBC treatment regimen.Therefore, this paper provides an overview and outlook of the application of NAC in MIBC treatment.

Objective To explore the clinical utility of endoclip papilloplasty in endoscopic retrograde cholangiopancreatography(ERCP).Methods A prospective study was conducted and selected 62 patients who underwent ERCP from November 2021 to November 2022.30 out of 32 patients who randomly underwent endoclip papilloplasty were successful.These patients were assigned to successful endoclip papilloplasty group(group A,n=30)or the duodenal papilla unclamping group(group B,n=30).The aim was to compare the difference in short-term and long-term complications between the two groups.Results The success rate of papillary plasty was 93.8%(30/32),with no statistically significant differences observed in the incidence of postoperative pancreatitis,postoperative hemorrhage after ERCP,and postoperative cholangitis between the two groups(P>0.05).The duodenal perforation rate was 0.There were no significant differences between the two groups in terms of total cholangitis incidence and recurrence rate of calculus of common bile duct within 1 year(P>0.05).However,there was a statistical difference in terms of total the incidence of cholangitis+calculus of common bile duct recurrence within 1 year(P<0.05).Conclusion The endoclip papilloplasty exhibits a high success rate and safety and feasibility procedure reducing long-term recurrence rate of cholangitis and calculus of common bile duct in endoscopic papillary large balloon dilation(EPLBD)procedure.

Objective:To study the relationship of pathogenic bacteria in midstream urine culture and stone composition of patients characteristics with infection stones.Methods:Between January 2016 and December 2020, 989 patients with infectious stones who attended Tsinghua Chang Gung Hospital, affiliated with Tsinghua University, for surgical treatment were enrolled in the study. There were 545 male and 444 female patients, with the mean age (48±14) years. The left and right side stones were 396 and 333, respectively. There were 260 bilateral stones, 264 single stones, 334 multiple stones, and 391 deer-stalker-shaped stones. The maximum diameter of stones was (33.4±26.5)mm, combined with diabetes in 109 cases and hypertension in 235 cases. Clean middle-urine was collected for bacterial culture, and intraoperative stone specimens were collected by percutaneous nephrolithotomy (PCNL). Personal characteristics of the patient such as gender, age, body mass index, clinical information such as stone size, location, comorbidities, results of urine culture and stone composition were recorded. The differences of infectious stone composition was analyzed between urease-producing, non-urease-producing bacteria.Results:Among the 989 patients with infectious stones, 259 were pure infectious stones, 131 were mixed infectious stones, and 599 were combined with infectious stone components. Urine cultures were positive in 627(63.4%) patients with infectious stones. The predominant urease-producing bacteria included Ureaplasma urealyticum(94 case), Proteus mirabilis(58 case), and Staphylococcus spp.(36 case). Pure infectious stones were common in Proteus mirabilis, while combined with infectious stone components were common in Ureaplasma urealyticum and Staphylococcus spp. The predominant non-urease-producing bacteria included Escherichia coli(175 case), Enterococcus spp.(76 case) and Streptococcus spp.(35 case). Escherichia coli commonly contained in infectious stone components and pure infectious stones, whereas Enterococcus spp. and Streptococcus spp. commonly contained in infectious stone components. Escherichia coli (61 case), Proteus mirabilis (44 case) and Enterococcus spp.(20 case) were the most common bacteria in 259 cases of pure infectious stones. Escherichia coli (36 case), Enterococcus spp. (14 case) and Ureaplasma urealyticum (10 case) were the most common bacteria in 131 cases of mixed infectious stones. The most common bacteria in 599 cases of combined infectious stones were Escherichia coli (78 case), Ureaplasma urealyticum (68 case) and Enterococcus spp. (42 case).Conclusions:Urease producing bacteria were not common in infectious stones. It was common for the Ureaplasma urealyticum in combined infectious stone components, while Escherichia coli was common in pure and combined infectious stone components.

Objective:To explore the status and influencing factors of peripherally inserted central catheters (PICC) related thrombosis in lung cancer patients undergoing chemotherapy.Methods:From June to December 2020, a total of 259 lung cancer patients undergoing chemotherapy in the First Affiliated Hospital of Zhengzhou University were enrolled using the convenient sampling method, and the occurrence of PICC related thrombosis within 3 months was recorded. Patients were divided into the thrombus group (18 cases) and the non-thrombosis group (241 cases) according to the occurrence of PICC associated thrombus. Univariate and multivariate Logistic regression analysis were used to explore the influencing factors of PICC related thrombosis in lung cancer patients undergoing chemotherapy.Results:The incidence of PICC related thrombosis of 259 lung cancer patients undergoing chemotherapy was 6.95% (18/259). Univariate analysis showed that there were significant differences in lung cancer stage, pathological type, complications, catheter placement limb, central venouscatheter material, catheter tip position, fibrinogen (Fg) and D-dimer (D-D) between the thrombosis group and the non-thrombotic group ( P<0.05). Multivariate Logistic regression analysis showed that Ⅲ-Ⅳ stage lung cancer, polyurethanecatheter, catheter tip position was 2/3 upper of the superior vena cava, Fg>4 g/L and D-D>0.4 mg/L were the influencing factors of PICC related thrombus in lung cancer patients undergoing chemotherapy ( P<0.05) . Conclusions:PICC related thrombosis in lung cancer patients undergoing chemotherapy is related to lung cancerstage, central venous cathetermaterial, catheter tipposition, Fg and DD. Medical staff should select appropriate catheter materialfor the patients, monitor coagulation-related factors closely, so as to reduce the risk of PICCrelated thrombosis.

Objective:To discuss the influence of mindfulness-based stress reduction plus micro-class education on the complications and knowledge mastery rate in surgical patients with diabetes mellitus.Methods:A total of 105 patients, diagnosed as diabetes mellitus complicated with appendicitis in the Affiliated Hospital of Chengde Medical College were selected from January 2019 to January 2020. They were hospitalized for laparoscopic appendectomy and were randomly divided into the control group ( n = 52) and the study group ( n = 53) in accordance with the random number table. The patients in the control group were given routine nursing care, and the patients in the study group were given mindfulness decompression therapy combined with micro-classroom education. The blood glucose control and psychological emotion of the two groups before and after operation, and the postoperative complications and the mastery rate of disease knowledge of the two groups were compared. Results:There was no significant difference in blood glucose indexes between the two groups at baseline ( P>0.05); FBG, HbA1c and other indicators in the two groups were improved during operation and 24h after operation, but FBG (7.38±0.54) mmol/L, HbA1c (6.39±0.21)% and FBG (6.90±0.52) mmol/L and HbA1c (6.10±0.39)% in the study group were lower than those in the control group [(8.16±1.21) mmol/L, (7.53±1.05)%, (7.60±0.57) mmol/L, (6.50±0.41)%], the difference was statistically significant ( t value was 6.789-13.264, P < 0.05); there was no significant difference in SAS and SDS scores between the two groups at baseline ( P > 0.05), until discharge, the SAS and SDS scores of the treatment group were 35.81±5.49 and 42.08±4.91 respectively, which were significantly lower than those of the control group (42.21±5.53, 6.51±4.72) respectively, compared with the corresponding scale scores of the control group, the difference between the two groups after treatment was statistically significant ( t value was 5.386, 4.265, P < 0.05). Compared with 17.31% (9/52) of the control group, the incidence of complications in the study group decreased to 5.66% (3/53), there was significant difference ( χ2 value was 6.789, P < 0.05). The qualified rate of disease knowledge mastery in the study group (98.11%,52/53) was significantly higher than that in the control group (86.53%, 45/52), and the difference was significant ( χ2 value was 5.062, P < 0.05). Conclusion:The mindfulness-based stress reduction plus micro-class education can effectively control the laparoscopic appendectomy patients blood glucose, stabilize the mental emotions, increase the illness knowledge mastery degree, keep in good mood, reduce the postoperative complications and promote the fast recovery.

Objective:To explore the effect of Xuanbai-Chengqi Decoction combined with conventional western medicine therapy for the coma patients with acute cerebral infarction. Methods:A total of 72 patients with acute cerebral infarction in Huaibei Hospital of Traditional Chinese Medicine from March 2019 to January 2020 were randomly divided into two groups with 36 in each group. The control group was treated with conventional western medicine therapy, and the treatment group was given Xuanbai-Chengqi Decoction by nasal feeding on the basis of the control group. Both groups were treated for 7 days. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the degree of neurological deficit, and the Full Outline of Unresponsiveness Scale (FOUR) was used to evaluate the degree of consciousness disorder of patients. Three-dimensional reconstruction of head CT was performed to identify and mark the edema area. The levels of serum high-sensitivity C-reactive protein (hs-CRP), homocysteine (Hcy) and vascular endothelin-1 (ET-1) were measured by double antibody sandwich enzyme-linked immunosorbent assay. The adverse events during treatment were observed and the clinical effective rate was evaluated. Results:The total effective rate was 100% (36/36) in the treatment group and 86.1% (35/36) in the control group, and the difference between the two groups was statistically significant ( Z=-0.242, P=0.015). On the 3rd and 7th day after treatment, the NIHSS scores of the treatment group were significantly lower than those in the control group ( t values were 26.567 and 17.982, all Ps<0.01). On the 3rd and 7th day after treatment, the eye opening response, motor response, brainstem response, brain stem response and total scores (3 days after treatment, t=15.235 , 14.892, 18.452, 11.232, 16.235; 7 days after treatment, t=19.5 68, 16.232, 10.356, 9.546, 11.098) of the treatment group were significantly lower than those in the control group. The levels of serum hs-CRP, Hcy, ET-1 and CT threshold of brain edema in the treatment group were significantly lower than those in the control group after treatment ( t=22.352, 17.789, 11.908 and 19.652, all Ps<0.01). There were no adverse drug reactions, no abnormal changes in blood routine tests, liver function and electrocardiogram in both groups. Conclusion:The Xuanbai-Chengqi Decoction combined with conventional western medicine therapy can improve the neurological function and promote awakening of coma patients with acute cerebral infarction, which may be related to reducing the levels of inflammatory cytokines related to hs-CRP, Hcy and ET-1, improving microcirculation and relieving brain edema.

Objective:To investigate the correlation of blood pressure variability within 24 h after thrombolysis with symptomatic intracerebral hemorrhage (sICH) and 90 d outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke treated with recombinant tissue plasminogen activator in the Department of Neurology, Jinshan Branch, Shanghai Sixth People's Hospital from January 2017 to May 2019 were enrolled prospectively. The baseline data of the patients were collected. The patients were divided into sICH group and non-sICH group according to the changes of head CT and the National Institutes of Health Stroke Scale (NIHSS) score after thrombolysis. At 90 d after thrombolysis, the modified Rankin scale was used to evaluate the outcomes, and the patients were divided into a good outcome group (0-2) and a poor outcome group (3-6). The blood pressure within 24 h after thrombolysis was monitored and the parameters related to blood pressure variability in 5 time periods (0-2 h, 2-6 h, 6-12 h, 12-18 h, and 18-24 h) were calculated, including systolic blood pressure (SBP) and diastolic blood pressure (DBP) maximum (max), minimum (min), maximum and minimum difference (max-min) and mean (mean). The differences between the adjacent blood pressures were calculated, the standard deviation (SD), successive variation (SV), rise successive variability (SVrise), drop successive variability (SVdrop), the maximum squared difference in blood pressure rise (SVrisemax), the maximum squared difference in blood pressure drop (SVdropmax) were calculated and recorded, respectively. Multivariate logistic regression analysis was used to evaluate the effect of various blood pressure variability parameters on sICH and the outcomes after intravenous thrombolysis. Results:A total of 112 patients receiving intravenous thrombolysis were included in the study. Their median age was 71 years (range, 38-92 years), 66 were males (58.9%); median baseline NIHSS score was 10. Seventeen patients (15.2%) developed hemorrhagic transformation, 10 of them (8.9%) were sICH. The 90-d follow-up showed that 73 patients (65.2%) had a good outcome, 39 (34.8%) had a poor outcome and 7 of them (6.3%) died. There were significant differences in hypertension ( P=0.029), ischemic heart disease ( P=0.012), total cholesterol ( P=0.033), baseline NIHSS score ( P=0.003) between the sICH group and the non-sICH group. There were significant differences in age ( P=0.025), gender ( P=0.005), atrial fibrillation ( P=0.003), etiologic classification of stroke ( P=0.003), baseline NIHSS score ( P<0.001) and sICH ( P=0.003) between the poor outcome group and the good outcome group. In addition, there were significant differences in multiple blood pressure variability parameters among the above groups (all P<0.05). Multivariate logistic regression analysis showed that DBP SVdropmax, 6-12 h DBP SV, 12-18 h DBP SV, 6-12 h DBP SVdrop, 12-18 h DBP SVdrop were the independent risk factors for sICH after intravenous thrombolysis (all P<0.05); 2-6 h SBP SV, 2-6 h SBP SVrise, 2-6 h SBP SVdrop, 2-6 h DBP SV, 2-6 h DBP SVrise and 2-6 h DBP SVdrop were the independent risk factors for poor outcome after intravenous thrombolysis (all P<0.05). Conclusions:Early blood pressure and some blood pressure variability parameters are closely related to sICH and outcomes after intravenous thrombolysis in acute ischemic stroke. Closely monitoring of blood pressure and its variability can help clinical management and outcome prediction after intravenous thrombolysis.

Objective To compare and study the two kinds of quality control methodologies related to intelligent quality management system ( iQM) and traditional quality control , and the quality control performance of iQM equivalent to traditional quality control were evaluated , ensuring the accuracy of the results of blood gas testing.Methods Beijing Chaoyang Hospital of Capital Medical University , Beijing Tiantan Hospital of Capital Medical University , Shanghai Longhua Hospital of Shanghai University of Chinese Medicine, and Sichuan Provincial People′s Hospital, these 4 medical institutions were selected to implement this study.During the period from June 2016 to December 2016, in the routine detection of total 3 712 specimen, the iQM and traditional quality control modes were used simultaneously to calculate the mean values of all blood gas parameters quality controls , SD, CV (%) and Sigma values, to evaluate the quality control performance and difference of the two quality control modes .Results During the process of testing blood gas samples from 3 712 specimen in 4 hospitals, iQM process control solution ( PCS) A, B, C ran 1 089, 7 678 and 154 quality control samples respectively , and 732 external quality control samples were run by traditional quality control mode .Considering the most sensitive parameters of blood gas testing pO 2, iQM PCS A, B, C′s Sigma value are higher than 8, however, the traditional quality control′s Sigma value are less than 6; For parameters pCO2, pO2and Na+, there exists significant difference between two quality control methods (P＝0.004 8,P＝0.000 1,P＝0.004 4,P＜0.01), other parameters pH, K+, Ca ++, Glu, Lac and Hct, there exists no significant difference between two quality control methods (P＝0.250 6, P＝0.062 3,P＝0.034 0,P＝0.346 9,P＝0.186 3,P＝0.823 1,P＞0.01).Totally 22 errors detected by iQM, includes 14 micro-clots and 8 interferences samples, which were not detected by traditional quality control .Conclusions The error in blood gas analysis mainly comes from the pre-analytical phase.iQM enhanced specimen inspection capabilities and make up for the inability of traditional quality control to monitor the quality of specimens , enabling full-scale, real-time, and dynamic monitoring of each specimen , powerful error detection capabilities , and automatic error correction capabilities . Besides, automatic documentation saves staff much time.The system can effectively ensure the accuracy of blood gas test results, meet the quality requirements of related laws and regulations and related industry standards , and also can meet the clinical intended use , providing new ideas for POCT quality management and improvement.

Objective To investigate the correlation between tumor metastasis with T cell subsets and cytokines in the pa tients with primary hepatocellular carcinoma (HCC).Methods Ninety-seven cases of primary HCC were prospectively collected from January 2014 to January 2016 and assigned into the metastasis group (38 cases) and non-metastasis group(59 cases) according to whether suffering from metastasis.Surgical specimens were obtained from all pauents and flow cytometry was used to detect the CD4+,CD8+ T cell proportion in HCC tissue,paracancerous tissues and peripheral blood.Moreover,ELISA was adopted to detect the peripheral blood IL-6,IL-10,TNF-α and IFN-γ levels.Results Compared with the non-metastasis group,the CD4+ T cell proportion of HCC tissue in the metastasis group was significantly increased(P=0.02),while the CD8+ T cells were significantly decreased (P=0.015).There was no statistical difference in CD4+ T cells proportion in the paracancerous tissue between the two groups (P=0.328).However the CD8+ T cells proportion of paracancerous tissue in the metastasis group was significantly higher than that in the non-metastasis group (P=0.021).There was no statistically significant difference in the proportion of CD8+ T cells in peripheral blood of the two groups (P=0.362).The proportion of CD4+ T cells in peripheral blood of the metastatic group was significantly lower than that in non-metastasis group (P=0.032).When compared with non-metastasis group,the metastasis group got a decreased level of peripheral blood IL-6 (P =0.012);while the IL-10 level was significantly increased (P =0.006);the TNF-α level and IFN-γ level were significantly decreased(P=0.000,P=0.035).Conclusion The patients with primary HCC have obvious T cell subsets and cytokines imbalance.

Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.
