Objective:To investigate the impact of body composition and inflammatory nutritional indicators on postoperative complications in patients with obstructive colorectal cancer,and to develop and validate a nomogram model.Methods:This is a retrospective case series study. The clinical data of 293 patients with obstructive colorectal cancer who were treated at the Department of Gastrointestinal Surgery,the Affiliated Hospital of Qingdao University,between January 2016 and January 2024,were retrospectively collected. The cohort included 182 males and 111 females,aged (65.0±12.1) years (range: 18 to 80 years). The dataset was randomly divided into a training group ( n=196) and a validation group ( n=97) with a 7∶3 ratio. Independent sample t test and multivariate logistic regression analysis were employed to identify independent risk factors associated with postoperative complications in patients with obstructive colorectal cancer. A preoperative nomogram model was subsequently developed for predicting postoperative complications,which was further validated using a validation cohort. Results:The training group comprised 119 males and 77 females,with 68 cases experiencing postoperative complications and 128 cases without complications. The validation group included 63 males and 34 females,with 30 cases experiencing postoperative complications and 67 cases without complications.Univariate analysis and multivariate analysis revealed that low skeletal muscle index ( OR=0.867,95% CI: 0.795 to 0.947),high visceral fat index ( OR=1.058,95% CI: 1.028 to 1.089),high systemic immune inflammation index ( OR=1.002, 95% CI: 1.000 to 1.003), low prognostic nutritional index ( OR=0.847,95% CI: 0.782 to 0.917),and preoperative anemia ( OR=2.714,95% CI: 1.161 to 6.344) were independent risk factors for postoperative complications (all P<0.05). A nomogram prediction model based on these five indicators was established. The area under the receiver operating characteristic (ROC) curve for the prediction model was 0.878 (95% CI: 0.829 to 0.928) in the training group and 0.849 (95% CI:0.767 to 0.930) in the validation group. Conclusions:The preoperative nomogram model,which incorporates inflammatory and nutritional indicators,demonstrates a good accuracy in predicting postoperative complications for patients with obstructive colorectal cancer. This model can effectively assist in guiding treatment decisions.

Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.

Objective:To observe the effect of Weijinkang Oral Liquid on rats'models with siliconic nodules and the diffuse fibrosis of the lungs.Methods:45 rats were randomly divided into the blank group,dust-affected group,and treatment group.The rats in the blank group were fed in normal environment.The rats in the dust-affected group were given regular feed.The dust-affected rats in the treatment group were administrated 1.0mL/100g of Weijinkang condensed liquid in 30% by stomach perfusion,two times daily(33 times of human's dosage).Five of each group were killed and anatomized in turn on the 15th day,the 30th and the 90th day.Results:On the 90th day the pathological test showed massive cartilaginous changes projecting to the pulmonary surface in the dust-affected group.There was no abnormality of lungs in both treatment group and blank group.After receiving Weijinkang Oral Liquid the rats in the treatment group showed greater weights than those in the dust-affected group,and the weights of fresh and dehydrated lungs were lighter than those in dust-affected group.Conclusion:Weijinkang Oral Liquid had certain effect on siliconic nodules and the diffuse fibrosis of the lungs caused by pneumonoconiosis.

Objective:To collect and evaluate the information of literature on perimenopausal syndrome.Methods:The computer retrieval method supplemented by manual inspection of literature.Results:590 relevant documents were retrieved and among which 129 were comprehensively studied.Conclusion:The quality of the literature should be improved though there was an annual quantitive increase of the literature on perimenopausal syndrome in TCM.Great efforts should be made in this aspect.

Objective To evaluate the therapeutic effect of combination of sandostatin and growth hormone (GH) in the treatment of severe acute pancreatitis (SAP ). Methods Sixty patients with SAP were divided randomly into 3 groups:(1)Sandostatin treatment(ST) group (n=15);(2)combination of sandostatin with GH treatment(CT) group (n=30) ;(3)control group (n=15). The changes in serum IL-1, IL-6,TNF-? and albumin levels after treatment, and the incidence of complications, the duration of hospital stay and cost were compared among the 3 groups. Results The complications, mortality, duration of hospital stay in the CT group were significantly shorter than those in ST group and control group (all P
