Objective:To assess the effect of patient-controlled intravenous analgesia (PCIA) with different postoperative analgesics on prognosis after colorectal surgery. Methods:A total of 460 colorectal cancer patients (TNMⅠ-Ⅱ) who underwent elective surgery within January 2010 to December 2012 in Chongqing Cancer Hospital were randomly divided into five groups for PCIA with sufentanil, dezocine, butorphanol, morphine, and tramadol. We evaluated the analgesic efficacy, detected NK cell activity and Th1/Th2 ratio from peripheral blood, and observed short-term complications and long-term cancer recurrence and metastasis. Healthy volunteers served as the control group. Results:The morphine group displayed a VAS score of less than 3 in the rest state and showed the longest hospital stay and the highest incidence of pruritus (P<0.05). The incidence of postoperative nausea and vomiting was the highest in the tramadol group (P<0.05). NK cel activity and Th1/Th2 ratio decreased in al experimental groups after surgery. NK activity and Th1/Th2 ratio returned to the control level 7 days after surgery in the tramadol and sulfentanil groups and 14 days after surgery in the dezocine and butorphanol groups (P>0.05), whereas those in the morphine group remained low (P<0.05). The incidences of cancer recurrence and metastasis were ranked as follows:morphine>butorphnol>dezocine>sufentanil>tramadol. Conclusion:Tramadol and sufentanil used in PCIA after colorectal surgery could facilitate the recovery of immune function and reduced the incidence of recurrence and metastasis.

OBJECTIVETo observe the effects of acupuncture-moxibustion on chronic allograft nephropathy (CAN) and explore the methods of acupoint selection along meridian for transplanted-kidney-related diseases.

METHODSA total of 180 patients of CAN were randomized into a syndrome differentiation group, a spleen-meridian group, a kidney-meridian group and a control group, 45 cases in each one. A total of 33 cases dropped out before the end of the study, including 8 cases in the syndrome differentiation group, 12 cases in the spleen-meridian group, 13 cases in the kidney-meridian group and no case in the control group. Patients in the control group were treated with conventional western medicine; based on this, patients in other three groups were treated with acupuncture-moxibustion. In the syndrome differentiation group, Qihai (CV 6), Hegu (LI 4), Guanyuan (CV 4), Feishu (BL 13), Shenshu (BL 23), etc. were selected for qi deficiency of lung and kidney; Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), etc. were selected for deficiency of qi and yin; Ganshu (BL 18), Shenshu (BL 23), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), Ququan (LR 8), etc. were selected for yin deficiency of liver and kidney; Zhongji (CV 3), Guanyuan (CV 4), Mingmen (GV 4), Guanyuanshu (BL 26), etc. were selected for yang deficiency of spleen and kidney. In addition, Sanyinjiao (SP 6), Diji (SP 8), Yinlingquan (SP 9), Xuehai (SP 10), etc. were added in the spleen-meridian group; Taixi (KI 3), Zhaohai (KI 6), Fuliu (KI 7), Ciliao (BL 32), etc: were added in the kidney-meridian group. Serum creatinine (Scr), creatinine clearance (Ccr) and 24-hour urinary protein before and after the treatment were com- pared among the four groups.

RESULTSAfter treatment, 24-hour urinary protein in the acupuncture-moxibustion groups and control group were all reduced (all P < 0.05); compared before treatment, the Scr in the spleen-meridian group was significantly reduced (P < 0.05); the difference of Ccr before and after treatment was insignificant in all the groups (all P > 0.05). Compared with the control group, 24-hour urinary protein in spleen-meridian group could relieve or recover the damage of transplant kidney induced by CAN. A new interlink may be established between the transplanted kidneys and the spleen meridians, indicating that transplanted kidney-related diseases can be treated by selecting acupoints of spleen meridian.

Objective To investigate the correlation between serum levels of antiphospholipid antibody(aPL)(ACA-IgG,ACA-IgM,β2-GPI-IgG,β2-GPI-IgM),LAC,ds-DNA,and ANA and preterm labor with pre-maturity,and to analyze the prediction of preterm labor with the combination of age,week of gestation,history of delivery,and history of miscarriage,so as to provide references for the prevention and treatment of preterm la-bor and to promote eugenics.Methods Through a retrospective study design,43 pregnant women with preterm la-bor with preeclampsia diagnosed and treated at Guangdong Provincial People's Hospital from June 2018 to Decem-ber 2020 were collected as a case group,and 47 healthy pregnant women of the same period and similar gestational age were randomly selected as a control group.aPL(ACA-IgG,ACA-IgM,β2-GPI-IgG,β2-GPI-IgM)and ds-DNA were detected by enzyme immunoassay(ELISA)using an enzyme immunoassay instrument,lupus anticoagulant(LAC)in plasma was detected by coagulometer,and ANA was detected by indirect immunofluorescence using an immunofluorescence analyzer,and the application of SPSS 24.0 software was used to statistically analyze the gen-eral information and laboratory test data.the age of the patients was combined,gestational week,birth history,miscarriage history and other general information,logistic regression analysis was performed to find the indepen-dent influencing factors related to preterm labor;the analysis was performed by using the subjects'work charac-teristic curve(ROC curve)to determine the area under the ROC curve(AUC),the best predictive value,sensi-tivity and specificity,and to analyze the predictive value of preterm labor with preterm labor.Results In this study,the pregnant women in the group of pregnant women with preterm labor with preeclampsia were aged 27～40 years,with a mean age of(29.93±3.91)years,and the gestational weeks at the time of blood collection were 27-36 weeks,with a mean gestational week of(31.96±2.35)weeks,while the pregnant women in the healthy control group during the same time period were aged 25～40 years,with a mean age of(30.74±3.44)years,and the gestational weeks at the time of blood collection were 28～36 weeks,with a mean gestational week of(32.84±2.13)weeks.In the same period,healthy control group pregnant women were aged 25～40 years,with a mean age of(30.74±3.44)years,and were 28～36 weeks pregnant at the time of blood collection.The β2-GPI-IgM level of pregnant women in the case group with preterm labor was significantly higher than that of pregnant women in the healthy control group at the same time,with statistically significant differences(P<0.05),while the differences in the levels of β2-GPI-IgG,ds-DNA,and LAC between the two groups were not statistically significant(P>0.05).The analysis of the ROC curves showed that the AUC of β2-GPI-IgM was 0.642(P<0.05),which was the highest in the preterm group,and the AUC was 0.642(P<0.05).0.05),which was an independent influencing factor of preterm labor;age,gestational week,labor history,and miscarriage history could not be used as independent in-fluencing factors of preterm labor.Conclusion β2-GPI-IgM is associated with threatened preterm labor,it can be used as a predictor of threatened preterm labor,and has clinical utility in the monitoring of threatened preterm labor in pregnant women.

As a ligand-dependent transcription factor,retinoid-associated orphan receptor γt(RORyt)that controls T helper(Th)17 cell differentiation and interleukin(IL)-17 expression plays a critical role in the pro-gression of several inflammatory and autoimmune conditions.An emerging novel approach to the therapy of these diseases thus involves controlling the transcriptional capacity of RORyt to decrease Th17 cell development and IL-17 production.Several RORyt inhibitors including both antagonists and inverse agonists have been discovered to regulate the transcriptional activity of RORyt by binding to orthosteric-or allosteric-binding sites in the ligand-binding domain.Some of small-molecule inhibitors have entered clinical evaluations.Therefore,in current review,the role of RORyt in Th17 regulation and Th17-related inflammatory and autoimmune diseases was highlighted.Notably,the recently developed RORyt inhibitors were summarized,with an emphasis on their optimization from lead compounds,ef-ficacy,toxicity,mechanisms of action,and clinical trials.The limitations of current development in this area were also discussed to facilitate future research.

Objective: To explore the genetic basis for a pedigree affected with Marfan syndrome (MFS). Methods: Clinical data of the patients was collected.With genomic DNA extracted from peripheral blood samples, potential mutation was detected by targeted exome sequencing.Candidate variants were validated by Sanger sequencing and bioinformatic analysis. Results: Targeted exome sequencing and Sanger sequencing revealed a missense c. 649T>C(p.Trp217Arg) variant in the exon 7 of FBN1 gene, which was unreported previously.Bioinformatics analysis suggested that the variant can cause amino acid replacement and affect the structure and function of fibrillin-1. Conclusion A novel missense variant of the FBN1 gene was identified, which probably underlies the autosomal dominant MFS in this pedigree.
