Objective To study the inhibition effect of non custodial terpenes-3β-alcohol to experimentally in-duced autoimmune encephalomyelitis in guinea pigs. Methods Different doses (25 mg/kg, 50 mg/kg and 100 mg/kg) of non custodial terpenes-3β-alcohol were given to the experimentally induced autoimmune encephalomyelitis model of guinea pigs by gavage for 8 weeks. Plasma levels of CD4+/CD8+, IL-1, IL-2, IL-6, IL-10, neuropeptide Y (NPY), beta endorphin (β-EP) , transforming growth factor-β(TGF-β), matrix metalloproteinase (MMP-2), nitric oxide synthase (NOS) and leuko-cyte differentiation antigen CD3 were assessed. The brain neuron morphology changes was observed under light microscopy while its ultrastructure changes was observed under electron microscope. NOS expression in neurons was observed through immunofluoresce technology. Results Non custodialterpenes-3β-alcohol inhibited the increase of plasma CD4+/CD8+, IL-1, IL-2, IL-6, IL-10, MMP-2, CD3 and NPY while decrease of plasmaβ-EP, brain TGF-β. It also increase NOS expres-sion in neuronal cytoplasm and maintained neuron morphology. Conclusion Non custodial terpenes-3β-alcohol inhibit-ed the experimental autoimmune encephalomyelitis in guinea pig.

Objective To investigate the effect of creatine phosphate sodium on postoperative fatigue syndrome (POFS) in gastric carcinoma patients. Methods Nighty cases of radical resection in gastric cancer were randomly divided into control group (n=45) and treatment group (n=45).Normal saline (100 mL) and phosphocreatine sodium (2 g) was admin-istrated intravenously after anaesthesia induction in treatment group while only normal saline was given in control group . After operation, the two groups of patients were all treated with enteral and parenteral nutrition. General performance was ob-served in both groups. Fatigue score (VAS score) was measured on the day before the operation,the first,third and fifth day after operation. Body weight, triceps skinfold thickness (TSF), mid upper arm circumference (AMC), plasma total protein (TP), plasma albumin (ALB) and prealbumin (PA) were examined at the same time. Results The total effective rate of the control group and the study group were 73.3%and 95.6%respectively and the difference was of statistically significant. Fa-tigue scores (VAS score) was significantly difference in both groups pre- and post-operation time points, also between 2 groups. Body mass, TSF and AMC in time points postoperation were all lower than those in the time point of preoperation. TP, ALB and PA of two groups in postoperative time points were significantly different compared with those in preoperative time point. The above indexes were all decreased with postoperation time, and these indexes in treatment group were signifi-cantly better than those in control group. Conclusion Creatine phosphate sodium can alleviate postoperative fatigue, im-prove nutritious status and promote early rehabilitation of patients.

Objective To study the radiation-protective effect of diallyl disulfide(DADS)in germ cells of male mice. Methods Male mice were whole-body exposured to 4 Gy X-ray irradiation to establish a animal radiation damage model. Testicular histology, sperm motility and sperm deformity rate were observed, protein carbonyl content, malondialdehyde(MDA)and 8-hydroxy deoxyguanosine(8-OHdG)content were tested to assess the degrees of radiation damages of sperm cells and protective effect of DADS. Testicular tissue antioxidant enzymes such as superoxide dismutase (SOD),catalase(CAT),glutathione peroxidase(GSH-px)activity and glutathione(GSH)content were examined. The expression of Nrf2 signal protein was detected to explore the radiation-protective mechanism of DADS. Results Compared with the pure exposure group, the testicular tissue damages in the DADS pretreatment group were milder, sperm motility increased significantly(P< 0.05)and sperm deformity rate decreased(P< 0.05), and the protein carbonyl content, MDA and 8-OHdG levels significantly reduced(P< 0.05). The antioxidant indexes of SOD, CAT, GSH-px and GSH were markedly improved(P< 0.05),and the expression of Nrf2 was dramatically enhanced. Conclusions DADS has a protective effect on acute radiation injury in germ cells of male mice by means of anti-oxidative ability.

Objective To evaluate the effects of network video in the continuing nursing care of discharged cervical cancer patients with postoperative catheter.Methods A number of 53 patients with cervical cancer underwent radical hysterectomy in Nantong Tumor Hospital from January to December 2016 were randomly recruited as the observation group. Another 53 patients with cervical cancer underwent radical hysterectomy from January 2012 to December 2015 were retrospectively studied as control group. Patients in the control group were discharged from the hospital with removal catheter after the professional nursing of 15 days. Patients in the observation group were discharged from the hospital with the indwelling catheter one week after the surgery, and the catheter was removed after one week of network video on continuation nursing care.Results After the removal catheter, there were two cases (4％) of increased residual urine, two cases (4％) of urinary retention, and eight cases (15％) of urinary tract infection in the observation group;one case (2％) of increased residual urine, two cases (4％) of urinary retention, and eight cases (15％) of urinary tract infection were found in the control group. No differences were observed between the two groups (P>0.05). The score of patients' satisfaction was (4.85±0.12) in the observation group and (4.82±0.10) in the control group, with no difference between the two groups (t=1.479,P>0.05).Conclusions The application of network video in continuing nursing care of patients with cervical cancer after radical hysterectomy is feasible, whereas the preparation before discharge is required.

Background and Aims:Preoperative sarcopenia is a syndrome characterized by reduced skeletal muscle mass and strength,and it is associated with various adverse postoperative outcomes.Gastric cancer patients may experience transient or persistent postoperative cognitive dysfunction(POCD),which significantly impacts their quality of life and prognosis.However,it remains unclear whether this complication is linked to sarcopenia.Therefore,this study was conducted to investigate further the impact of preoperative sarcopenia on postoperative complications and long-term outcomes in patients undergoing radical gastric cancer surgery,with a particular focus on the relationship between sarcopenia and POCD,in order to provide insights for preoperative assessment and postoperative management of gastric cancer patients. Methods:The clinical data of gastric cancer patients who underwent radical surgery in the Third Department of Surgery at the Fourth Hospital of Hebei Medical University between January 2014 and January 2015 were retrospectively collected.Patients were divided into the sarcopenia and non-sarcopenia groups based on preoperative L3 skeletal muscle index,handgrip strength,and gait speed measurements.The clinicopathologic characteristics of sarcopenic patients,as well as the impact of sarcopenia on short-term clinical outcomes and long-term prognosis,were analyzed.Additionally,factors influencing the development of POCD were determined. Results:A total of 320 gastric cancer patients were included,of whom 59(18.44％)were diagnosed with sarcopenia.Compared with the non-sarcopenia group,sarcopenic patients had significantly lower bady mass index,serum total protein,serum albumin,and hemoglobin levels,with a higher proportion of patients aged ≥60 years,NRS 2002 score ≥3,comorbid pulmonary disease,and those undergoing open surgery(all P＜0.05).After balancing the baseline characteristics of the two groups using propensity score matching(PSM),each group included 59 patients.The analysis revealed that the overall incidence of postoperative complications was higher in the sarcopenia group than in the non-sarcopenia group(54.24％vs.32.20％,P=0.016).The sarcopenia group also had a significantly higher incidence of Clavien-Dindo grade Ⅱ-Ⅳ complications and postoperative infectious complications(27.12％vs.5.08％,P=0.001;33.90％vs.15.25％,P=0.019).The average hospital stay was significantly longer for sarcopenic patients(12.54±4.7 d vs.7.68±3.8 d,P=0.005).Additionally,the 5-year overall survival(OS)and disease-free survival(DFS)rates were lower in the sarcopenia group compared to the non-sarcopenia group(both P＜0.05).Cox multivariate analysis showed that sarcopenia,tumor pT stage,and tumor pN stage were independent risk factors for 5-year OS and DFS.At the same time,adjuvant chemotherapy was a protective factor for prognosis(all P＜0.05).Among the 118 patients after PSM,34(28.81％)were diagnosed with POCD.Logistic multivariate regression analysis indicated that preoperative sarcopenia,the number of preoperative comorbidities,and anesthesia duration of ≥2 h were independent risk factors for POCD,while intraoperative use of dexmedetomidine was a protective factor(all P＜0.05). Conclusion:Preoperative sarcopenia is closely associated with unfavorable postoperative outcomes and the development of POCD in patients undergoing radical gastric cancer surgery.Clinicians should emphasize the detection of sarcopenia during preoperative evaluation and implement proactive interventions and postoperative management strategies to improve clinical outcomes and long-term survival rates.
