AIM:This study aims to investigate the effects of Jiedu-Shengji ointment(JDSJG)on wound healing in diabetic rats by modulating the protein kinase R-like endoplasmic reticulum kinase(PERK)/inositol-requiring enzyme 1(IRE1)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)pathway in the context of endoplasmic reticulum stress(ERS).METHODS:Male Sprague-Dawley rats were randomly assigned to four groups:control group,model group,detoxification muscle ointment group,and sulfadiazine silver cream group.All groups,except the control,were administered an intraperitoneal injection of 45 mg/kg streptozotocin to induce diabetes.The control and model groups received daily applications of normal saline,while the detoxification myogen ointment and sulfadiazine silver cream groups received their respective treatments daily.After dressing changes,wounds were bandaged with sterile gauze.Following 14 d of continuous treatment,wound healing was assessed and healing rates calculated.Histopathologi-cal changes in wound tissues were analyzed using HE staining.Transmission electron microscopy was utilized to observe the number,morphology,and swelling of endoplasmic reticulum in the wound tissues.The expression and distribution of PERK,IRE1 and thioredoxin interacting protein(TXNIP)was assessed by immunohistochemistry,while Western blot was used to measure the levels of apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),TXNIP and NLRP3.ELISA was conducted to quantify the inflammatory cytokines interleukin-18(IL-18)and IL-1β.RE-SULTS:After 14 d of intervention,significant differences were observed in wound tissue parameters across the groups.The model group exhibited a significantly lower wound healing rate compared to the control group(P<0.01),with in-creased wound exudation,poor granulation tissue growth,and elevated the protein levels of PERK,IRE1,TXNIP,CHOP,NLRP3 and ASC(P<0.01),as well as significantly higher levels of IL-1β and IL-18(P<0.01).In contrast,the detoxification muscle ointment group showed a marked improvement in wound healing rate(P<0.01),reduced inflamma-tory exudation,improved granulation tissue growth,and significant decreases in TXNIP expression(P<0.01),along with lower levels of PERK,IRE1,CHOP,ASC and NLRP3(P<0.01).Additionally,the IL-1β and IL-18 were significantly reduced(P<0.01).CONCLUSION:Jiedu Shengji ointment alleviates excessive ERS and mitigates chronic inflammato-ry responses,thereby promoting the healing of diabetic wounds.These effects may be attributed to the inhibition of exces-sive activation of the PERK/IRE1/NLRP3 pathway.

Objective To investigate the immediate effects of lower limb with open chain weight-adding on joint position sense and gait symmetry in stroke patients. Methods From January, 2016 to January, 2017, 39 stroke patients were included. Their joint position sense and gait symmetry were compared before and after weight-adding. The joint position senses of active reproduction of active positioning (ARAP) and passive reproduction of passive positioning (PRPP) were assessed during lower limb straight leg raise. The gait symmetry was also as-sessed and three indexes were recorded including the symmetry of foot rotation angle, step length and percentage of single leg support phase. Results After weight-adding, the position sense of PRPP did not improve (t=0.832, P=0.832), nor of the symmetry of foot rotation an-gle (t=-0.704, P=0.483) and percentage of single leg support phase (t=0.381, P=0.702);the position sense of ARAP improved (t=3.158, P=0.011), as well as the symmetry of step length (t=2.022, P=0.041). Conclusion The lower limb with open chain weight-adding could im-prove the active joint position sense and symmetry of step length.

Objective To evaluate J-pouch coloanal anastomosis after low anterior resection for the middle and low rectal carcinoma. Methods From January 1998 to July 2002, 120 patients undergoing low anterior radical resection for the middle or low rectal carcinomas were divided into groups of coloanal anastomosis and that of 5 cm colonic J-pouch-anal anastomosis. WT5”HZResults These two groups were well matched for gender, age and histologic stage. There were no significant differences in operative time, hospital stay, complications, postoperative recurrence rate and postoperative survival time between the two groups as founded by an average follow-up of 18 months. The mean distance from the inferior edge of the tumor to the dentate line was (3 6?1 5) cm in the J-pouch group, significantly less than that in coloanal anastomosis group of (5 2?1 9) cm, ( P =0 000). Defecation frequency, urgency and incontinence were significantly improved at 3 months and 12 months after operation in the J-pouch group ( P 0 05). Conclusion J-pouch coloanal anastomosis after low anterior resection for the middle and low rectal carcinoma significantly improves the short-term bowel function after operation.

Objective To analyze clinicopathological features of synchronous colorectal carcinoma. Methods Data of colorectal cancer patients admitted to our hospital from June 1994 to December 2003 were analyzed retrospectively. Patients were divided into multiple synchronous colorectal carcinoma group ( MCG) and single colorectal cancer group ( SCG). Clinicopathological features and prognosis were compared between the two groups. SPSS 10. 0 was used for data analysis. Results Of all colorectal cancer(CRC) patients,3. 2 % (39/1225) had multiple synchronous CRCs and 939 patients had sporadic single CRC. In MCG, two patients had hereditary nonpolyposis colorectal cancer ( HNPCC) syndrome. No significant differences were found between MCG and SCG with regard to demographic features, Dukes stage and differentiation of index CRC. More patients in MCG had metachronous CRC (x2 = 4. 545, P= 0.033) and colorectal polyps ( x2 = 12. 013, P = 0.001) compared with SCG. Forty-six percent of multiple synchronous CRCs located in right colon in MCG, which was higher than that in SCG ( x2 = 25. 757 ,P = 0. 0001). Malignancy in adenoma was the frequent event accompanying cancer in MCG. Five-year survival rate in MCG was 57% compared with 64% in SCG ( x2 =0.084, P = 0.772 ). Conclusion Patients with right colon cancer seem easily to have multiple synchronous CRCs and malignancy in adenoma is most frequently accompanying the cancer. For patients with multiple synchronous CRCs, the prognosis is equivalent to that of patients with SCG.

Objective To investigate the lymph node metastases in gastric carcinoma and its clinical significance Methods The clinicopathological data of 608 patients with gastric carcinoma were analyzed retrospectively The total metastatic rate was calculated Binary logistic regression analysis was used to analyze the influence index of ten clinicopathological factors on the No 7~9 lymph node metastases Results The metastases rate (44 4%) of No 3 group lymph node was the highest seconded by No 15 group (43 2%) The overall lymph node metastases in No 7~9 group was 37 5% The depth of tumor invasion and the lymph node metastases in No 1~6 group were significantly correlated with lymph node metastases in the No 7~9 group ( P

Objective To investigate the prognostic significance of extended resection for locally advanced colorectal carcinoma. Methods Clinical data of 960 cases of colorectal cancer hospitalized for surgery between Jan 1995 and Dec 2002 were reviewed, and complication rates, perioperative mortality, 5-year survival were calcualated, prognostic factors were analyzed using Cox regression model. Results Sixty-six patients with locally advanced colorectal carcinoma were treated with extended resection, accounting for 6.9% of the total cases. Surgical complication rate in this subgroup was 27.3% (18/66), relatively higher than that of conventional resection for colorectal carcinoma (?~2 =8.82, P=0.002). The perioperative mortality was zero. Pathology showed that carcinoma invasion into the adjacent organs resected en bloc was 31% (27/88), the 5-year survival rate was 62%. The tumor spreading into the adjacent organ (Wald=7.42,P=0.005) and lymph node status (Wald=4.55, P=0.035) were found to be the independent prognostic factors. Conclusions Extended resection for locally advanced colorectal carcinoma resulted in a favorable prognosis. Postoperative complication was relatively high, but still acceptable.
