Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Background While A few studies have suggested associations between ambient temperature and cardiac autonomic function, the relationship between hourly temperature variations and heart rate variability (HRV) remains unclear. Objective To examine the acute effects and lag patterns of short-term ambient temperature exposure on HRV at an hourly temporal resolution during cold and warm seasons, and to further characterize the exposure-response relationships. Methods We conducted a longitudinal panel study involving 1047 eligible participants who ordered repeated 24 h ambulatory electrocardiogram monitoring at the First Affiliated Hospital of Xinjiang Medical University in Urumqi, Xinjiang Uygur Autonomous Region, China, between March 2020 and March 2022. Twelve HRV parameters were extracted, including standard deviation of all NN intervals (SDNN), standard deviation of the 5 min averages of NN intervals (SDANN), standard deviation of NN intervals index (SDNNIDX), root mean square of successive differences of adjacent NN intervals (rMSSD), triangle index (TI), percent of NN50 in the total number of NN intervals (pNN50), total power (TP), ultralow frequency (ULF), very low frequency (VLF), low frequency (LF), high frequency (HF), and ratio of low frequency to high frequency (LF/HF). Hourly meteorological data (mean temperature and relative humidity) were obtained from the nearest monitoring stations to participants' residences. Linear mixed effects models (LME) and generalized additive mixed effects models (GAMM) were employed to assess temperature-HRV associations and lag patterns during cold (from October to March next year) and warm (from April to September) seasons, with stratification by sex and age. Results A total of 1047 Urumqi residents who had repeated 24 h ambulatory electrocardiograms were included in this study. In both cold and warm seasons, the exposure-response relationship between ambient temperature and HRV showed an approximately linear negative correlation with no threshold effect; HRV parameters decreased as ambient temperature increased. The correlation between ambient temperature and HRV usually began at a lag of 6 h and disappeared around 24 h lag. The cold season induced a stronger effect on HRV decline, and for every 1 °C increase in ambient temperature during the cold season from lag 0 to 6 h, SDNN decreased by 0.72%, SDNNIDX decreased by 1.46%, TI decreased by 0.07%, SDANN decreased by 1.23%, rMSSD decreased by 1.00%, pNN50 decreased by 2.74%, TP decreased by 3.30%, ULF decreased by 3.74%, VLF decreased by 3.76%, LF decreased by 2.75%, HF decreased by 2.49%, and LF/HF decreased by 0.74%; for every 1 °C increase in ambient temperature during the warm season, SDNN decreased by 0.56%, SDNNIDX decreased by 1.08%, TI decreased by 0.29%, SDANN decreased by 0.56%, rMSSD decreased by 0.68%, pNN50 decreased by 2.11%, TP decreased by 2.64%, ULF decreased by 3.14%, VLF decreased by 2.74%, LF decreased by 1.85%, HF decreased by 1.68%, and LF/HF decreased by 0.47%. Conclusion Elevated ambient temperatures in Urumqi are significantly associated with decreased HRV in the residents, affecting cardiac autonomic function.

Patients who initiated peritoneal dialysis (PD) in Sichuan Provincial People's Hospital from January 1, 2001 to December 31, 2013 were enrolled in the single center and retrospective study. Clinical and laboratory data were collected to analyze the long-term survival rates, technique survival rates and associated influencing factors. Patients were followed up until December 31, 2021 or endpoints occurred (death or stopping PD treatment). Kaplan-Meier survival curves were used to estimate survival rates and technique survival rates. Cox proportional hazards regression model was used to analyze the risk factors of death and technique failure in PD patients. A total of 373 patients were enrolled in the study, with age of (52.1±15.8) years old and 199 (53.4%) males. During the follow-up, 154 (41.3%) patients died, 72 (19.3%) patients transferred to hemodialysis, and 40 (10.7%) patients received kidney transplant. Kaplan-Meier survival curves revealed that overall survival rates of PD patients at 1, 3, 5, 7, and 10 years were 92.2%, 76.6%, 66.0%, 52.4% and 38.6%, respectively. Technique survival rates were 93.5%, 84.8%, 74.2%, 62.8% and 44.5% at 1, 3, 5, 7, and 10 years, respectively. Multivariate Cox regression model results showed that age ( HR=1.055, 95% CI 1.039-1.073, P<0.001), transfer from hemodialysis ( HR=2.212, 95% CI 1.514-3.231, P<0.001), episodes of peritonitis ( HR=2.141, 95% CI 1.194-3.837, P=0.011), Charlson comorbidity index ( HR=1.525, 95% CI 1.305-1.783, P<0.001), and baseline albumin ( HR=0.951, 95% CI 0.925-0.978, P<0.001) were independent influencing factors of survival in PD patients. Episodes of peritonitis ( HR=2.327, 95% CI 1.274-4.250, P=0.006) and Charlson comorbidity index ( HR=1.244, 95% CI 1.035-1.496, P=0.020) were independent influencing factors of technique survival in PD patients. PD patients have good early survival rates and technical survival rates, but long-term outcomes need to be further improved. Peritonitis is a major risk factor for low long-term survival rates and technical survival rates in PD patients.

Objective:To investigate the correlation between preeclampsia and thyroid dysfunction in pregnancy.Methods:107 early pregnant women with preeclampsia admitted to our hospital from Jan. 2017 to Jan. 2020 were all enrolled (observation group) . The observation group were in 6-34 gestational weeks, with an average parity of (1.67±0.35) times. In addition, 100 cases of normal pregnant women in the same period were selected as the control group. The control group were in 6-34 gestational weeks, with an average parity of (1.61±0.31) times. The two groups were compared at early, mid and late pregnancy in terms of thyroid function, and the correlation of preeclampsia and abnormal thyroid function was analyzed.Results:1. TSH levels in the observation group were (1.92±1.24) , (2.07±0.82) , and (2.30±1.23) mU/L in the first trimester, second trimester and third trimester, respectively, showing an upward trend. The difference between the two groups was statistically significant ( P=0.024) . FT4 levels of the observation group in the first trimester, second trimester and third trimester were (0.80±0.26) , (0.60±0.34) and (0.59±0.32) pmol/L, respectively, showing a decreased trend and the difference was statistically significant compared with those of the control group ( P=0.012) . 2. The incidence of hypothyroidism, TPOAb positive and reduced free tetraiodothyronine in the observation group was significantly higher than that in the control group ( P=0.001, 0.023, 0.005) . There was no significant difference in the incidence of hyperthyroidism or subclinical hypothyroidism between the two groups ( P=0.169, 0.846) . 3. Correlation analysis showed that preeclampsia was related to hypothyroidism, normal thyroid function with TPOAb positive and reduced free tetraiodothyronine ( P=0.000, 0.000, 0.000) . Conclusions:There are changes in thyroid function in pregnant women with preeclampsia. Hypothyroidism, positive TPOAb and reduced free tetraiodothyronine are closely related to the onset of preeclampsia.

For improving epitope immunogenicity and achieving the co-immunization, late protein 1 (L1) of HPV type 16 (HPV16L1) was selected as the vector to carry the dominant epitope of Toxoplasma gondii because of the shared common population between Toxoplasma gondii and human papillomavirus (HPV). RSepitope-HPV16L1 (RSepitope fused at the "N-terminus" of HPV16L1) and HPV16L1-RSepitope (RSepitope fused at the "C-terminus" of HPV16L1) chimeras were constructed. After transfection of COS-7 cells with the recombinants, Western blot, RT-PCR, and immunofluorescence experiments confirmed that RSepitope-HPV16L1 could successfully express the corresponding mRNA and protein of RSepitope and HPV16L1, but the HPV16L1-RSepitope construct could not. A "prime-boost" immunization program was applied in mice to further evaluate the immune response elicited by the constructs, and the RSepitope-HPV16L1 immunization group produced the most significantly increased humoral and cellular immune responses (the highest RSepitope-specific IgG antibody level and the highest IFN-γ production, respectively), in which both elevated Th1 and Th2 immune responses were obtained. Moreover, the advantage of HPV16L1 as an epitope carrier was remarkable for RSepitope-HPV16L1, which induced a more prominent immunological response than RSepitope alone (without fusion with HPV16L1). Our research indicated that the N-terminus of HPV16L1 could be a better insertion site for enhancing target epitope immunogenicity, and our study offers a design for epitope vaccine of reasonable combination.

Objective To evaluate the clinical value of 3D reconstruction in the single utility-port thoracoscopic segmentectomy of early stage NSCLC by propensity score matching (PSM). Methods We retrospectively analyzed clinical data of 150 early stage NSCLC patients undergoing single utility-port thoracoscopic segmentectomy. The patients were divided into reconstruction group (n=58) and non-reconstruction group (n=92) according to 3D reconstruction. PSM was performed on two groups to compare perioperative outcomes. Results Procedures were successfully completed on all patients, without perioperative death. In each group, 43 patients were successfully matched after PSM on the basis of 8 confounding factors, age, gender, smoking status, BMI, maximum tumor diameter on CT, tumor location, % FEV1 and type of planned segmentectomy. After PSM, in complex segmentectomy, the patients in the reconstruction group had shorter operation time (155.77±30.17 vs. 212.94±66.49min, P < 0.001) and less blood loss (46.00±25.94 vs. 88.79±68.36ml, P=0.002), compared with the non- reconstruction group. Conclusion Preoperative 3D reconstruction could help improve the efficiency of single utility-port thoracoscopic surgery for complex segmentectomy and reduce intraoperative bleeding.

Objective: To detect the vascular paths in the lateral wall of maxillary sinus using cone beam computer tomography (CBCT), and to retrospect the surgical managements of avoiding bleeding complication during the lateral approach maxillary sinus elevation.Methods: The documents of 71 consecutive patients with 81 sides maxillary sinus elevation surgery were collected.The vascular paths in the lateral wall of maxillary sinus were detected by the preoperative CBCT, and the messages about the vascular in surgical records were analyzed.Results: The paths of the vascular could be detected in 77 (95.1%) sides maxillary sinus in the reconstruction panoramic images of CBCT.At the position of the first molar, the paths of the vascular of the lateral maxillary sinus walls could be detected in 54 sides (66.7%) in the reconstruction coronal images of CBCT, and the other 27 sides (33.3%) could not be detected.Two approximately parallel paths of the vascular were found in 3 sides (3.7%) of the lateral maxillary sinus walls.The different diagnoses occurred in 6 sinuses between two observers.The kappa of diagnostic consistency of the two observers was 0.842 (P<0.001).The mean distance between the lower border of the vascular path to the plane of the alveolar crest of 54 sides maxillary sinuses was about (13.0±4.7) mm.The mean distance between lower border of vascular path to the plane of the floor of the sinus was (9.3±4.8) mm.The vascular path was located in the floor wall in 1 sinus.During the lateral approach maxillary sinus elevation operation, intraosseous vessels were dissected in 4 sides sinus lateral wall, the vascular path was avoided consciously in 3 sides, and the sinus elevation surgery had to be given up in 1 side for the vessel was torn and bleeding.There were no vascular related messages in 73 sides of the lateral approach maxillary sinus elevation operation records.Conclusion: The vascular paths of maxillary sinus wall could be detected by CBCT in most cases.Preoperative CBCT examination was proved to be reliable.The vascular paths of maxillary sinus wall should be examined carefully.It was helpful to make the surgical design perfectible and reduce the risk of tearing the vessel in operation.

Objective To investigate the combined effects of alcohol consumption and obesity hypertension risk. Methods Based on data from program“Prevention of multiple metabolic disorders and metabolic syndrome in Jiangsu province”, Baseline data were obtained in April 1999 to Jun 2004, we conducted the follow up investigation from March 2006 to October 2007 for subjects, those follow up time meet 5 years. A total of 4 083 participants completed the follow-up survey, and 2 778 eligible participants for final analysis. In the baseline and follow up survey, participants returned a completed questionnaire with information on diet, education, occupation, lifestyle factors, and medical history. Data on demographic characteristics, physical examination and laboratory tests were also obtained. Cox proportional hazards regression model was used to investigate the association between body mass index (BMI), waist circumference (WC) and waist to height ratio (WHtR). Logistic regression model was used to examine the interaction of alcohol consumption with WC, BMI and WHtR on risk of hypertension and the relative excess risk due to interaction (RERI), the attributable proportion due to interaction (AP), and the synergy index (SI) were calculated. If the 95% CI of SI do not include 1, the 95% CI of RERI and AP do not include 0, the interactions are statistically significant. Results In the study subjects, 660 patients (254 males and 406 females) were new cases, who developed hypertension by the follow-up investigation. The mean of WC, BMI and WHtR were(23.3 ± 3.2)kg/m2,(77.7 ± 9.0)cm and 0.49 ± 0.06, were higher than that in normal subjects ((22.4 ± 3.0) kg/m2,(74.8 ± 8.5) cm and 0.47 ± 0.05, all P values<0.001). After adjustment for age, sex, smoking status, family history of hypertension, the hazard ratio of EH for participants with obesity, high WC, high WHtR and alcohol consumption were higher, the HR(95%CI) were 2.12 (1.46-3.10), 1.64 (1.32-2.03), 2.80 (1.73-4.59) and 1.65 (1.29-2.12). HR(95%CI) of subjects with both abnormal BMI and current alcohol consumption was 2.76 (2.45-3.17), SI(95%CI) was 1.60 (0.48-5.28),RERI(95%CI) was 0.66 (-0.47-1.79) and AP was 0.24 (-0.22-0.69), HR(95%CI) of subjects with both high WC and current alcohol consumption was 4.93 (2.87-8.49), SI(95%CI) was 4.49(1.97-10.22),RERI(95%CI) was 3.06 (0.48-5.64) and AP(95%CI) was 0.62 (0.41-0.83), HR(95%CI) of subjects with both high WHtR and current alcohol consumption was 2.80 (1.73-4.59), SI (95%CI) was 2.14 (0.88-5.17),RERI was 0.96 (0.48-5.64) and AP (95%CI) was 0.34 (0.03-0.68). Conclusion Both obesity, high WC, high WHtR, and alcohol consumption were strong risk factors of EH, and impact of an additive interaction of alcohol consumption and high WC on EH risk existed.
