Objective To investigate the association between baseline normal neutrophil/lymphocyte ratio(NLR)changes and the risk of diabetic peripheral neuropathy(DPN).Methods A total of 200 type 2 diabetes mellitus(T2DM)patients admitted to our hospital from November 2016 to November 2021 were retrospectively selected.They were divided into DPN group(87 cases)and T2DM group(113 cases)according to whether peripheral neuropathy was present.In the verification group,there were 26 T2DM patients combined with DPN.Multivariate Cox regression analysis was used to analyze the risk factors affecting DPN.A homogram prediction model was constructed.Receiver operating characteristic(ROC)curve and calibration curve were used to evaluate the predictive efficiency of the model.All patients were followed up for 1 year to compare the effects of changes in NLR on the risk of new DPN and nerve conduction velocity.Results DM duration(HR 2.358,95%CI 1.754～3.658),triglyceride(HR 3.085,95%CI 2.454～6.778),baseline NLR(HR 3.145,95%CI 1.466～5.632)were risk factors for DPN.The model of line graph has good distinction and accuracy.Elevated NLR(HR 3.258,95%CI 1.678～4.694)and high baseline NLR(HR 2.365,95%CI 1.547～4.526)were independent risk factors for new DPN after 1 year in the DPN-free group(P<0.05).There is a significant negative correlation between NLR and nerve conduction velocity in patients with T2DM(P<0.05).Conclusions Within the baseline normal range,the higher the NLR ratio,the greater the risk of DPN and the slower nerve conduction velocity,which is not conducive to the prognosis of patients.

This article summarized Professor You Zhaoling's clinical experience in the treatment of polycystic ovary syndrome(PCOS).It is believed that kidney deficiency and blood stasis are the basic etiology and pathogenesis,with liver and spleen disorders.Clinical treatment is based on tonifying the kidney and replenishing essence,promoting blood circulation and resolving stasis,supplemented by soothing the liver,strengthening the spleen,and resolving dampness;treatment should also be based on the patients'stage of illness,age,and body type;basic body temperature and B-ultrasound should be skillfully uses to monitor ovulation,and four methods of regulating bubbles were creatively created;an original hypothetical menstrual stimulation method for PCOS patients with menstrual disorders was created.Professor You's clinical experience has demonstrated the characteristics of TCM treatment,providing a new approach for the TCM treatment of PCOS.

Objective:To explore whether the 15-minute retention rate (R15) of indocyanine green (ICG) in the indocyanine green excretion test and the effective hepatic blood flow (EHBF) can predict the occurrence of mild hepatic encephalopathy (MHE).Methods:Using the convenience sampling method, we collected clinic data from 153 patients diagnosed with liver cirrhosis or liver failure from June 2019 to December 2019 in the Third Affiliated Hospital of Sun Yet-sen University in Guangzhou. We screened the MHE patients with the number connect test-A and the digital symbol test, and analyzed the clinical data. By taking different values for R15 and EHBF as cut-off points, the significance of the two factors in predicting MHE is explored respectively.Results:The incidence of MHE was 38.56% (59/153). Single factor analysis showed that the difference of Child-Pugh grade between the MHE group and the non-MHE group was statistically significant ( χ2 value was 7.606, P<0.05), while the differences between cirrhosis and liver failure diagnosis, fasting blood glucose, and serum creatinine were not statistically significant ( P>0.05). When most points between 0.11 and 0.61 were selected as normal and abnormal cut-off points of R15, R15 had statistical significance ( P<0.05) and when R15 selected 0.18, it was most significant (Fisher exact test P=0.00024). When most points between 0.08 and 0.76 were selected as normal abnormal cut-off points of EHBF, EHBF had statistical significance ( P<0.05) and when EHBF selected 0.25, it was most significant (Fisher exact test P=0.00022). Through Logistic stepwise regression analysis, the risk factors for MHE were R15 and EHBF. The ROC curve was used to illustrate the predictive effects of two factors on MHE. Conclusions:The incidence of MHE in patients with cirrhosis or liver failure is high. When R15≥0.18 or EHBF≤0.25 L/min, R15 and EHBF in indocyanine green excretion test can better predict the occurrence of MHE than Child-Pugh classification, and can be help to evaluate and manage patients in time.

Objective:The operative approach and steps of laparoscopic right hemicolon cancer radical resection have been standardlized and professional consensus has been reached. However, some detailed issues such as the handling of Henle's trunk and whether to preserve the right gastroepiploic vein (RGEV) still remain controversial. This study investigates the safety, feasibility, short- and long-term outcomes of preserving RGEV during laparoscopic right hemicolectomy.Methods:A retrospective cohort study was carried out. Clinical data of 92 patients undergoing laparoscopic right hemicolectomy in Taizhou People's Hospital from March 2016 to May 2018 were retrospectively analyzed. All the patients were treated with complete mesocolon resection (CME) and had complete postoperative pathological data and follow-up data. Based on the tumor location, 49 patients preserved RGEV (preservation group) and 43 did not (non-preservation group). Pathological data, postoperative complications, short- and long-term outcomes were compared between the two groups.Results:There were no significant differences in baseline data between the two groups (all P>0.05). No significant differences were found in operation time, intraoperative blood loss, unplanned reoperation, anastomotic leak, number of harvested lymph nodes, number of metastatic lymph node, and time to food intake after surgery between two groups (all P>0.05). Compared with non-preservation group, the preservation group had faster recovery of anal gas passage after operation [(3.1±1.0) days vs. (4.0±1.7) days, t=-2.787, P=0.007], shorter length of hospitalization [(11.5±1.5) days vs. (15.0±7.9) days, t=-2.823, P=0.007], and reduced the hospitalization expenses [(46 000±5000) yuan to (57 000±33 000) yuan, t=-2.076, P=0.044]. No postoperative gastroparesis (PGS) occurred in the preservation group, while 6 cases in the non-preservation group developed gastroparesis during perioperative period ( P<0.05). The median time of follow-up time was 31.8 (5.2-43.7) months. The overall survival time of the preservation group and non-preservation group was (35.4±1.8) months and (37.6±1.7) months, respectively without significant difference ( P=0.336); the disease-free survival was (32.0±2.2) months and (35.5±2.0) months, respectively without significant difference as well ( P=0.201). Conclusions:Dissection of the Henle's truck and preservation of RGEV is safe and feasible during laparoscopic right hemicolectomy, which can significantly reduce the incidence of postoperative gastroparesis, shorten the recovery time of postoperative intestinal function and hospitalization, and decrease the cost of hospitalization. The efficacy of RGEV preservation is similar to non-preservation of RGEV.

OBJECTIVE: To explore the feasibility, safety and the economical efficiency of double-pouch anastomosis in laparoscopic radical rectal cancer assisted by small incisions. METHODS: Clinical data of 224 patients undergoing gastrointestinal surgery at Taizhou People's Hospital of Jiangsu Province from January 2011 to December 2017 were retrospectively analyzed. Indusion criteria: patients were diagnosed as primary rectal adenocarcinoma by preoperative enteroscopy pathology, the distance of the tumor to anal margin was from 4 to 15 cm, and patients were treated with laparoscopic total mesorectal excision(TME) through small incision. Patients were divided into two groups according to different anastomosis method, double-pouch group(108 cases) and single-pouch group (116 cases). The surgical indexes, tumor safety indexes, short-term efficacy and economic indexes were compared between the two groups. RESULTS: There was no significant difference between two groups in baseline data, operative time, blood loss, number of lymph nodes dissection, average length of proximal and distal bowel, or incidence of urination and sexual dysfunction (all P>0.05). Compared with the single-pouch group, the double-pouch group presented lower anastomotic secondary bleeding rate [0.9%(1/108) vs. 6.0% (7/116), χ²=4.238, P=0.040], lower incidence of anastomotic leakage[1.9%(2/108) vs. 7.8%(9/116), χ²=4.179, P=0.041], lower incidence of anastomotic stricture [1.9% (2/108) vs. 8.6% (10/116), χ²=5.054, P=0.025], shorter hospital stay [(13.4±3.9) days vs. (15.9±9.8) days, t=2.524, P=0.013] and less average hospitalization costs [(34 000±7 000) yuan vs. (46 000±23 000) yuan, t=5.047,P<0.001]. There was no significant difference in local recurrence, distant metastasis or overall survival between the two groups during mean follow-up of 33 months (all P>0.05). CONCLUSION Laparoscopic TME assisted by small incision with double-pouch anastomosis is a safe, feasible and economical method.

OBJECTIVETo evaluate the feasibility, safety, radicality and short-term outcome of preserving left colic artery (LCA) during laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer.

METHODSFrom January 2013 to December 2016,136 patients with mid-lower rectal cancer received laparoscopic TME in the Gastrointestinal Surgery Department of Taizhou People's Hospital of Jiangsu Province. Patients with rectal tumor within 10 cm to the anal verge were enrolled into the study. All the enrolled patients had complete data of pathology and follow-up. Those receiving neoadjuvant chemoradiotherapy, with severe base diseases, multifocal tumor, tumor invasion of surrounding tissues, fixation of tumor, recurrent tumor, complications such as acute ileus, bleeding, perforation were excluded. In this study, 72 patients did not undergo preservation of LCA (high ligation group) and 64 patients underwent preservation of LCA (low ligation group). Operative parameters, clinicopathological data and short-term outcome were collected and compared between two groups.

RESULTSThe baseline data including gender, age, body mass index, tumor stage, and distance of tumor from anal verge of two groups were comparable (P>0.05). The differences between two groups about the mean time of operation and the operative blood loss were not significant [(164.0±12.6) min vs. (167.3±9.4) min, (30.0±3.6) ml vs. (30.1±3.0) ml, all P>0.05]. There was no operative death in both groups. Differences in the lymph node dissection (13.7±2.6 vs. 13.3±2.1) and the specimen length of proximal resection margin [(16.4±1.9) cm vs. (16.7±2.1) cm] or distal resection margins [(3.9±0.6) cm vs. (4.1±0.9) cm] between high and low ligation groups were not significant (all P>0.05). Compared with high ligation group, the low ligation group had higher rate of sphincter preservation [92.2% (59/64) vs. 79.2% (57/72), χ=4.580, P=0.032], lower rate of anastomotic leakage [1.6% (1/64) vs. 9.7% (7/72), χ=4.075, P=0.044], anastomotic stenosis [3.1% (2/64) vs. 12.5%(9/72), χ=4.006, P=0.045], and voiding and sexual dysfunction [6.3%(4/64) vs. 18.1%(13/72), χ=4.317, P=0.038]. Mean time of follow-up was 19 months. In high ligation group, the local recurrent rate was 5.56%, distant metastasis rate was 13.89%, overall survival rate was 90.28%, disease-free survival rate was 80.56%, while in low ligation group, the local recurrence rate was 4.69%, distant metastasis rate was 12.50%, overall survival rate was 90.63%, disease-free survival rate was 82.81%, whose differences between two groups were not significant (all P>0.05).

CONCLUSIONPreservation of LCA during laparoscopic TME for the treatment of rectal cancer is safe and feasible, which can reduce the incidence of anastomotic leakage and stenosis, and voiding and sexual dysfunction.

OBJECTIVETo evaluate the clinical significance of No.12 lymph node dissection for advanced gastric cancer with D2 lymphadenectomy.

METHODSClinicopathologic data and No.12 lymph node dissection of 256 advanced gastric cancer patients undergoing radical operation in our department between January 2005 and December 2010 were retrospectively summarized and the influence factors of metastasis in No.12 lymph nodes were analyzed.

RESULTSOf 256 patients, 179 were male and 77 were female with the average age of 59.2 years. Tumor located in the upper of stomach in 24 cases, middle of stomach in 41 cases, lower of stomach in 174 cases, multi-focus or diffuse distribution of stomach in 17 cases. Tumor diameter was <3 cm in 39 cases, 3 to 5 cm in 100 cases, >5 cm in 117 cases. Serum carcinoembryonic antigen (CEA) level increased in 61 cases, serum carbohydrate antigens (CA)72-4 increased in 56 cases and CA19-9 increased in 61 cases. The number of No.12 lymph nodes resected from all the patients was 1 152, and the average number was 4.5±1.9. The metastasis rate of No.12 lymph nodes was 9.4%(24/256) after hematoxylin eosin staining (positive group). All the patients received effective follow-up to December 2015, and the average follow-up time was 101.2 months. The median survival time of positive No.12 group (24 cases) was 29.8 months and of negative No.12 group (232 cases) was 78.2 months, whose difference was statistically significant (χ=21.715, P=0.000). Univariate analysis found that No.12 lymph node metastasis was not associated with age, gender, tumor differentiation (all P>0.05), but was associated with tumor location, tumor diameter, invasive depth (all P<0.05), and was closely associated with Borrmann type, outside metastatic lymph nodes of No.12 and high levels of serum CEA, CA72-4 and CA19-9 (all P=0.000). Multivariate regression analysis found that tumor location (RR=2.452, 95%CI:1.537 to 3.267, P=0.000), Borrmann type (RR=1.864, 95%CI:1.121 to 3.099, P=0.016) and number of outside metastatic lymph nodes of No.12 (RR=2.979, 95%CI: 2.463 to 3.603, P=0.000) were the independent risk factors of the No.12 metastasis (P<0.05).

CONCLUSIONSMetastasis in No.12 lymph nodes indicates poorer prognosis. The No.12 lymph nodes of advanced gastric cancer patients with curative resection, especially those with the tumor located in the lower part, Borrmann type IIII(, outside metastatic lymph nodes of No.12, should be regularly cleaned.
