BACKGROUND: The role of inflammation in the development of gestational diabetes mellitus (GDM) has recently become a focus of research. The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI), novel indices, reflect the body's chronic immune-inflammatory state. This study aimed to investigate the associations between the SII or SIRI and GDM. METHODS: A prospective birth cohort study was conducted at Beijing Obstetrics and Gynecology Hospital from February 2018 to December 2020, recruiting participants in their first trimester of pregnancy. Baseline SII and SIRI values were derived from routine clinical blood results, calculated as follows: SII = neutrophil (Neut) count × platelet (PLT) count/lymphocyte (Lymph) count, SIRI = Neut count × monocyte (Mono) count/Lymph count, with participants being grouped by quartiles of their SII or SIRI values. Participants were followed up for GDM with a 75-g, 2-h oral glucose tolerance test (OGTT) at 24-28 weeks of gestation using the glucose thresholds of the International Association of Diabetes and Pregnancy Study Groups (IADPSG). Logistic regression was used to analyze the odds ratios (ORs) (95% confidence intervals [CIs]) for the the associations between SII, SIRI, and the risk of GDM. RESULTS: Among the 28,124 women included in the study, the average age was 31.8 ± 3.8 years, and 15.76% (4432/28,124) developed GDM. Higher SII and SIRI quartiles were correlated with increased GDM rates, with rates ranging from 12.26% (862/7031) in the lowest quartile to 20.10% (1413/7031) in the highest quartile for the SII ( Ptrend <0.001) and 11.92-19.31% for the SIRI ( Ptrend <0.001). The ORs (95% CIs) of the second, third, and fourth SII quartiles were 1.09 (0.98-1.21), 1.21 (1.09-1.34), and 1.39 (1.26-1.54), respectively. The SIRI findings paralleled the SII outcomes. For the second through fourth quartiles, the ORs (95% CIs) were 1.24 (1.12-1.38), 1.41 (1.27-1.57), and 1.64 (1.48-1.82), respectively. These associations were maintained in subgroup and sensitivity analyses. CONCLUSION The SII and SIRI are potential independent risk factors contributing to the onset of GDM.

Objective To analyze the risk factors of short-term re-obstruction after plastic stent placement by endoscopic retrograde cholangiopancreatography(ERCP)in patients with hilar malignant biliary obstruction.Methods A retrospective study was performed on clinical data of 93 patients with hilar malignant biliary obstruction who underwent ERCP biliary plastic stent placement from January 2015 to January 2024.Understanding the effects of general information,clinical characteristics,operative-related factors,and laboratory-related indicators on postoperative short-term re-obstruction.The dependent variable was whether biliary stent re-obstruction in short-term after operation,univariate and multivariate Logistic regression analysis were used to analyze the risk factors for the patients with hilar malignant biliary obstruction occurred re-obstruction in short-term after ERCP plastic stent placement.Results Among the 93 patients,49 patients had short-term recurrent biliary stent obstruction after plastic stent placement by ERCP and the recurrence rate was 52.7%.Univariate analysis showed that gender,types of malignant biliary strictures,preoperative cholangitis,no drainage before operation and endoscopic sphincterotomy(EST)during ERCP plastic stent placement,location of stent placement,fever within 24 h after ERCP plastic stent placement,the decrease less than 50%of total bilirubin(TBiL)at 2 weeks after operation,the decrease less than＜50%of γ-glutamyl transpeptidase(GGT)at 2 weeks after operation,GGT and alkaline phosphatase(ALP)by less than 50%at 2 weeks after operation were potential risk factors affecting for short-term re-obstruction after ERCP plastic stent placement in patients with hilar malignant biliary obstruction.Multivariate analysis showed that,no drainage before operation(O＾R=5.738,P=0.013),preoperative cholangitis(O＾R=5.347,P=0.025)and place stents on the left or on the right(O＾R=6.739,P=0.014;O＾R=9.719,P=0.005)were independent risk factors for short-term re-obstruction after ERCP plastic stent placement.Conclusion No drainage before operation,preoperative cholangitis,place stents on the left or on the right are independent risk factors for short-term re-obstruction after ERCP plastic stent placement in patients with hilar malignant biliary obstruction.Early identification of risk groups and timely intervention of risk factors in clinical practice are of great significance for the prevention of short-term re-obstruction after ERCP plastic stent placement in such patients.

Objective To investigate the clinical efficacy of different stents placement under endoscopic retrograde cholangiopancreatography(ERCP)in patients with malignant biliary obstruction(MBO)and the effect on patient survival time.Methods Clinical data of MBO patients treated with ERCP stent placement between January 2020 and March 2024 were collected,divided into recyclable stent group(33 cases),metal stent group(42 cases),and ordinary stent group(34 cases).Comparation of the three groups of preoperative and postoperative changes in liver function,complications of long-term cholangitis and pancreatitis,stent patency time,success rate of stent removal with a single clamping,survival time,monitoring follow-up situation.Results There was no statistically significant difference in the liver function of the three groups of patients before stent placement(P>0.05);One week after stent placement,the difference compared with preoperative between direct bilirubin(DBiL)and total bilirubin(TBiL)in the recyclable stent group and the metal stent group was significantly higher than that in the ordinary stent group,and the difference between the ordinary stent group and other two groups was statistically significant(P<0.05).The incidence of cholangitis in the recyclable stent group was the lowest,followed by the ordinary plastic biliary stent,and the metal biliary stent had the highest incidence of cholangitis,the incidence of cholangitis in the long term after stent placement was compared among the three groups of patients with a statistically significant difference(P<0.05).The incidence of postoperative pancreatitis in the three groups was not statistically significant(P>0.05).The success rate of stent removal with a single clamping was higher in the recyclable stent group than the ordinary stent group.Comparison of median stent patency time among the three groups,the difference was statistically significant(P<0.05).The metal stent group had the longest median patency time of 194.0 d,recyclable plastic stent had the second longest median patency time of 126.0 d,and ordinary plastic biliary stent had the shortest median patency time of 92.0 d.Median survival time among the three groups was statistically significant(P<0.05).The recyclable plastic biliary stent had the longest median survival time of 590.0 d,metal biliary stent had the second longest median survival time of 476.0 d,and ordinary plastic biliary stent had the shortest median survival time of 453.0 d.Conclusion Recyclable plastic biliary stent has a faster decrease in bilirubin index compared with the ordinary stent group after operation.And the recyclable plastic stent group has lower incidence of long-term cholangitis,higher success rate of one-time clamping of the stent,and more advantages in time to stent patency and survival time compared with ordinary plastic biliary stent,which is an effective choice of stenting modality for ERCP stent placement in patients with MBO.

Objective To evaluate the effects of ultrasound-guided paravertebral nerve block(PVNB)and local infiltration anes-thesia on postoperative inflammation level and recovery quality of patients after robot-assisted radical nephrectomy.Methods A total of 100 patients who underwent elective robot-assisted laparoscopic radical nephrectomy in General Hospital of Central Theater Command from January 2022 to August 2022 were selected prospectively.They were randomly divided into observation group and control group by random number table method,with 50 cases in each group.The observation group chose general anesthesia combined with PVNB,while the control group chose general anesthesia combined with incision local infiltration anesthesia.All patients were connected with patient-controlled intravenous analgesia(PCIA)after operation.The pain visual analogue scale(VAS)of rest and cough,the systemic immune inflammatory index(SII),interleukin-6(IL-6),and the QoR-15 scores of the patients after operation in the two groups were recor-ded.The dosage of remifentanil,the times of effective compression of analgesia pump and remedial analgesia were recorded in the two groups.Adverse reactions and related complications were recorded.Results Compared with the control group,the pain VAS of rest and cough in the observation group were lower on first and second day after operation(P<0.05).SII and IL-6 were lower on the first and third day after operation(P<0.05).The QoR-15 scores on the first,second,and fifth day after operation were higher(P<0.05).The dosage of remifentanil was less during operation(P<0.01).The effective pressing times of intravenous analgesia pump were less af-ter operation(P<0.05).Lower incidence of remedial analgesia and adverse effects(P>0.05).Conclusion Compared with local in-filtration anesthesia,PVNB can provide better intraoperative and postoperative analgesia effect,reduce the early postoperative inflammato-ry reaction and accelerate the early recovery of patients for robot-assisted radical nephrectomy.

Objective:To investigate the efficacy of intensity-modulated radiotherapy with sequential chemotherapy in the treatment of high-grade glioma and analyze the influential factors.Methods:A total of 56 patients with high-grade glioma who received treatment in Yantai Municipal Laiyang Central Hospital from January 2014 to January 2016 were retrospectively analyzed. All patients underwent three-dimensional conformal radiotherapy or enhanced radiotherapy. The use of bevacizumab, pathological grade, and preoperative and postoperative Karnofsky Performance Status scores in all patients were recorded. Cox and other proportional risk regression models were used to analyze the predictors of patient mortality and receiver operating characteristic (ROC) curve analysis was performed.Results:All patients were followed up to April 2022. Follow-up results showed that the median survival time of patients receiving concurrent chemotherapy with temozolomide and adjuvant chemotherapy with temozolomide was 11.6 months. Univariate analysis showed that pathological grade, Karnofsky Performance Status scores, and the degree of tumor resection were correlated with the prognosis of patients ( P = 0.022, 0.049, 0.022). Multivariate analysis showed that the degree of tumor resection and pathological grade were the independent influential factors of prognosis ( P = 0.010, 0.010). Survival curve analysis revealed that the median survival time of patients subjected to total tumor resection was 12.6 months and that of patients subjected to partial tumor resection was 4.8 months. The median survival time of patients subjected to total tumor resection was longer than that of patients subjected to partial tumor resection. The median survival time of patients with WHO grade Ⅲ tumors was 25.2 months, and it was 6.3 months for patients with WHO grade Ⅳ tumors. The median survival time of patients with WHO grade Ⅲ tumors was longer than that of patients with WHO grade Ⅳ tumors. The receiver operating characteristic curve analysis results showed that the area under the receiver operating characteristic curve plotted for using WHO classification of tumors in the neurological system and surgical methods to predict the death of patients with high-grade glioma was 0.783 and 0.814, respectively. WHO tumor grade and surgical methods for prediction of prognosis of high-grade glioma had high accuracy. Conclusion:Low pathological grade and total resection are independent protective factors for the prognosis of patients with high-grade glioma.

OBJECTIVE To investigate the effects of esketamine combined with dexmedetomidine used for drug-induced sleep endoscopy in patients with obstructive sleep apnea syndrome. METHODS Totally 60 patients with obstructive sleep apnea syndrome were randomly divided into control group and observation group ，with 30 cases in each group. Anesthesia induction scheme of control group included loading dose of dexmedetomidine 1 μg/kg，pumped for 10 min，maintained at 1 μg（/ kg·h），and intravenous administration of propofol at a constant rate of 3 mg（/ kg·h）until the patient snored. That of observation group included same administration route and dose of dexmedetomidine as control group ，intravenous administration of esketamine 1 mg/kg at a constant rate of 0.5 mg/（kg·h）until the patient snored. Sleep endoscopy was performed when the bispectral index （BIS）was lower than 75 and the alert /sedation（OAA/S）score was higher than 1. The vital signs ，BIS and OAA/S scores of patients in awake state （T0），10 min load dose of dexmedetomidine infusion （T1），at the time of examination （T2）and at the end of examination （T3） were recorded ，as well as the patient ’s medication （including the one-time success rate of examination ，the number of additional drugs due to physical movement during examination ），and the occurrence of adverse events after medication. RESULTS In the comparison between groups ，the pulse oxygen saturation （SpO2）and BIS of patients in the observation group were significantly higher than those in the control group at T1，T2 and T3；the heart rates and mean arterial pressures （MAP）at T2 and T3 were significantly lower than those in the control group ；and the OAA/S score at T1 and T2 were significantly higher than those in the control group （P＜0.05）. Comparison within the group ，the heart rates at T1，T2 and T3 in the observation group were significantly lower than those at T0，and the MAP at T2 and T3 were significantly lower than that at T1（P＜0.05）；in control group ，compared with T0，SpO2 decreased significantly at T1，T2 and T3，heart rate decreased significantly at T1，and MAP increased significantly at T2（P＜0.05）. Sixty patients successfully completed drug-induced sleep endoscopy after medication. The one-time success rate of examination in the observation group was significantly higher （No.191460443） than control group （P＜0.05），and the number of additional drugs due to physical movement during examination was significantly less than control group （P＜0.05）. There was no significant difference in the incidence of adverse events between 2 groups（P＞0.05）. CONCLUSIONS Esketamine combined with dexmedetomidine has less respiratory inhibition and less effect on hypoxia hemodynamics in patients with obstructive sleep apnea syndrome. It has less intervention times in the process of sleep endoscopy ，and has more advantages than propofol.

Objective To study the pharmacological function of the aconitine in treating adjuvant arthritis(AA).Methods Fifty rats were randomly divided into the control group, AA model group, methotrexate group(0.5 mg/kg), and aconitine groups of different dosages (25, 100μg/kg). Except the control group, each group was injection of intradermal Freund's complete adjuvant (0.1 ml) into right hindpaw of rats to establish adjuvant arthritis model. On the 10th day after model onset, the aconitine were administered by gavage with 25, 100μg/kg once daily, and the methotrexate group was administered with 0.5 mg/kg methotrexate twice per week, and all groups were treated for 19 days. After the last administration, the foot swelling was measured by toe volume meter, arthritis index was calculated by 5-grade scoring method, spleen and thymus index were calculated, and the pathological changes of right ankle joint were observed by HE staining.Results After the model establishment, compared with the model group, the degree of swelling of the ankle at 20 days (668.7 ± 144.5μl, 566.9 ± 179.3μl vs. 912.1 ± 200.5μl), 24 days (833.1 ± 144.0μl, 803.9 ± 213.4μlvs.1069.5 ± 164.6μl) and 28 days (736.4 ± 115.0μl, 835.7 ± 170.1μlvs. 1107.2 ± 215.8μl) in the aconitine groups significantly decreased (P<0.05 orP<0.01). After the model establishment, compared with the model group, arthritic index scores at 18 days (3.1 ± 0.7, 3.2 ± 0.4vs. 3.8 ± 0.6), 24 days (3.1 ± 0.5, 3.4 ± 0.5vs.3.9 ± 0.3), 28 days (2.7 ± 0.6, 3.2 ± 0.9 vs. 4.0 ± 0.0) in the aconitine groups significantly decreased (P<0.05). Compared with the model group, the spleen index (3.5 ± 0.4, 3.3 ± 0.4, 4.0 ± 0.6vs.4.9 ± 0.5) respectively in the low and high dose group of aconitine and methotrexate group (P<0.01).Conclusion Aconitine has a certain degree therapeutic effect on AA rats.

Objective: To investigate the value of short tandem repeat (STR) genotyping in the diagnostic workup of molar and non-molar gestations with correlation of histological characteristics. Methods: Six hundred and fifty-six cases were selected based on clinically suspected hydropic abortion and/or molar pregnancy from July 2015 to September 2017 at Beijing Obstetrics and Gynecology Hospital. DNA was extracted from dissected chorionic villi and paired maternal endometrial FFPE tissue samples by Simplex OUP™ FFPE DNA Tissue Kit. STR genotyping was performed by PowerPlex 16 HS system. Results: DNA genotyping was informative in 649 of 656 cases, leading to identification of 215 hydatidiform mole gestations and 434 non-molar gestations. Most of non-molar gestations (375 cases, 86.4%) were diploid hydropic abortion. Various trisomy syndromes were found (53 cases, 12.2%), including trisomy 2, 3, 4, 7, 8, 13, 16 and 21. Only 2(0.5%) digynic triploid gestations were detected. Moreover, 4 cases (0.9%) of uniparental disomies (homologous or heterologous) were found. There were 196 cases with histologic diagnostic suspicious of hydatidiform moles were accurate sub-classified. Among them, 59 cases hydatidiform moles were under-diagnosed as diploid hydropic abortions, and 28 cases diploid hydropic abortions were over-diagnosed as hydatidiform moles.Compared with partial moles(PHM), there were no specific histomorphological features between the various types of non-molar gestations and partial moles for definitive diagnostic separation. There was no significant difference in the expression of p57^kip2 among PHM, trisomy and diploid hydropic abortions group (P=0.247). Conclusions STR genotyping can distinguish non-molar gestations from early hydatidiform moles, and efficiently avoid misdiagnosis based only on histological evaluation. Therefore, using STR genotyping, not only can the overdiagnosis of non-molar pregnancy be avoided, but also individualized management can be offered to patients including monitoring of serum hCG.

Objevtive To investigate the efficacy of Xuebijing injection combined with Ulinastatin for acute pancreatitis.Methods Databases were searched,like Pubmed,Embase,Cochrane Central Register of Controlled Trials (CENTRAL),China Biology Medicine disc (CBM),China National Knowledge Infrastructure (CNKI),Cochrane library,and Wangfang for randomized controlled trial (RCT) about the treatment of Xuebijing injection combined with Ulinastatin for acute pancreatitis.After evaluating the quality of literatures objectively,data were analyzed by RevMan 5.0 software.we evaluated abdominal pain relief time,recovery time of blood amylase,recovery time of white blood cell (WBC),concentration of interleukin (IL)-6,IL-8,tumor necrosis factor α (TNF-o) and total effective rate.Results Eleven studies and 893 patients were accepted into this article.Meta-analysis showed that abdominal pain relief time [weighted mean difference (WMD) =-1.71,95 ％ CI:-2.21,-1.21,P ＜ 0.01],recovery time of blood amylase (WMD =-1.82,95 ％ CI:-2.39,-1.25,P ＜ 0.01),recovery time of WBC (WMD =-2.75,95 ％ CI:-3.19,-2.31,P ＜ 0.01),and hospital stay time (WMD =-5.99,95 ％ CI:-7.73,-4.26,P ＜ 0.01)in experimental group was better than control group.Compared to control group,on the seventh day after treatment,inflammatory cytokines,including IL-6 [standardized mean difference (SMD) =-1.09,95％ CI:-2.66,0.48,P=0.17],IL-8 (SMD=-1.02,95％ CI:-1.66,-0.38,P＜0.01),andTNF-α (SMD =-1.10,95％ CI:-1.68,-0.53,P ＜ 0.01) were lower.In experimemal group,total effective rate was better than the control group (RR =1.16,95％ CI:1.07,1.25,P=0.0002).Conclusions Xuebijing injection combined with Ulinastatin for acute pancreatitis was more effective than traditional basal treatment or using Ulinastatin alone.However,the literature quality were mediocre,we need more large,random,double blind,and polycentric clinical study to prove further.
