Objective The purpose is to discuss the characteristics of the TCM syndromes of the patients with advanced gastric cancer, in order to reveal the pathological characteristics of Chinese medicine. Methods By observing the symptoms and signs of 126 patients with advanced gastric cancer, the TCM syndromes was used to analyze the distribution of TCM syndromes' frequency and the scores of symptoms. Results The resut showed that the common TCM syndromes for the disease location were stomach, spleen, liver, kidney, gallbladder, large intestine, small intestine, lung, utreus, heart, brain and bladder, where the frequency of stomach, spleen were higher than other. And the common TCM syndromes for the disease pathology were Qi deficiency, blood deficiency, Qi stagnation, blood stasis, toxin, phlegm, dampness, Yin deficiency, Qi revresion, heat, food stagnation, water stagnation and Yang deficiency.Conclusions The common TCM syndromes for the disease location of advanced gastric cancer were stomach, spleen, liver, kidney; And the common TCM syndromesfor the disease pathology were Qi deficiency and blood deficiency, Qi stagnation, blood stasis, toxin, phlegm, dampness, Yin deficiency, Qi revresion, heat, food stagnation, water stagnation and Yang deficiency.

This paper describes the analysis of insitu polymerization of monomeric reactants (PMR) polyimide resin solution by reversed phase ion pair suppression chromatography. the mobile phase consists of acetonitrile and water. The methyl sulphonic acid was used as an ion-pair reagent in the mobile phase. The addition of sodium perchlorate was required to increase the ionic strength of the mobile phase. The information was obtained on monomeric isomer distribution of PMR polyimide resin solution and purity of prepared materials.

Objective To investigate the clinical characteristics of 40 patients with ocular toxocariasis (OT) on the first attendance.Methods A total of 40 consecutive patients who were clinically and serologically diagnosed with OT were retrospectively reviewed.Results The mean age of patients was (12.12±10.42) years.There were 29 males and 11 females.29 cases presented with decreased vision,4 children with leukocoria,2 cases with strabismus and 5 cases was found abnormal during regular eye examination.Initially 8 eyes (20％) were misdiagnosed as retinoblastoma (1 eye),Coat' s disease (1 eye),cataract (2 eyes),iridocyclitis (2 eyes) and retinal detachment (2 eyes).23 eyes had retinal detachment,19 eyes had cataract.OT was the initial diagnosis for 15 patients (37.5％).The best corrected visual acuity (BCVA) were NLP to 0.7.Ultrasound biomicroscopy (UBM) were performed in 29 eyes,and identified peripheral granulomas in 23 eyes and adjacent tractional retinal detachment in 12 eyes.We also identified 17 cases (68.0％) with elevated IgE level among 25 patients with positive serological antibody test.Conclusions Tractional retinal detachment,vitreous opacities and cataract are the common clinical findings at the first attendance of OT patients.The adjunctive test of serum total IgE level may be helpful for the diagnosis.The application of UBM and specific IgG detection in serum and intraocular fluid,can also improve the diagnosis.

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.0 g) were matched according to body weight and randomly assigned to one of three groups: control, total body irradiation exposure (IR, 7.2 Gy) only, and IR (7.2 Gy) + SB203580 (15 mg x kg(-1)). 30 days survival rate was observed in the experiment. In intestinal injury experiment, the expression levels of caspase-3, Ki67, p53 and p-p38 were assayed in the mice intestine crypts. The results showed that the 30 days survival rate was 100% (control), 0 (IR) and 40% (IR+ SB203580), separately. Compared to the IR groups, the positive cells of caspase-3, p53 and p-p38 in crypt cells decreased 33.00%, 21.78% and 34.63%, respectively. The rate of positive cells of Ki67 increased 37.96%. Significant difference was found between all of them (P < 0.01). SB203580 potently protected against radiation-induced lethal and intestinal injury in mice, and it may be a potential radio protector.

Objective To explore the effect of posterior debridement, grafting and internal fixation for treatment of non-specific lumbar intervertebral infection. Methods Clinical data of 20 patients with non-specific lumbar intervertebral infection treated in General Hospital of Ningxia Medical University from October 2013 to June 2013 were retrospectively analyzed. There were 15 males and 5 females with an average age of 41 years (range, 36-51 years). All patients suffered from single lumbar inter-vertebral infection, including 3 cases at L2/3,4 at L3/4,10 at L4/5 and 3 at L5/S1. All 20 cases underwent one-stage posterior debride-ment, autogenous bone grafting and internal fixation, tissue samples in focus were collected for bacterial culture and pathological examination. The disease controlling statues were evaluated based on laboratory results of ESR and CRP. Imaging examinations were taken to evaluate the fusion of vertebral body. Clinical effects were evaluated using the visual analog scale (VAS) and the Jap-anese Orthopaedic Association scores (JOA) score of lumbar fumction. Results All patients underwent the surgery successfully. The surgery duration time was 90-160 min, average 125 min, and the blood loss was 200-700 ml, average 360 ml. Cerebrospinal fluid leakage occurred in one case. Postoperatively, all patients experienced significant reliefof back pain, improving in the func-tion of movement, and no fever. The lower back VAS score: average (5.35 ± 1.15) points before operation , average (2.76 ± 0.34) points one week after operation, and an average score of (0.85±0.65) points by the last follow-up time. JOA lumbar function score:all patients were effective after operation, the improvement rate was excellent in 65%(13cases), good in 25%(5 cases), and pass-able in 10%(2cases). Comparing with preoperation, the excellent and good rate was 90%. All patients ESR and CRP returned to normal levels at the last follow-up. Ordinary bacterial culture was positive in 8 cases and negative in 12 cases. The pathogens iden-tified were staphylococcus aureus (6 cases), Escherichia coli (2 cases) and staphylococcus epidermidis (2cases). All incisions achieved primary healing. All patients were followed up from 6-18 months (average,12 months), and the symptom of pain relieved significantly. No recurrent infection had happened. A solid bony fusion was found in all patients at 6-14 months (average, 8.5 months) after the surgery. Conclusion Posterior debridement, grafting and internal fixation are effective treatments for non-spe-cific lumbar intervertebral infection, can reduce the time of staying in hospital, this operation is safe and reliable.

Objective To investigate the long-term efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of primary biliary cholangitis (PBC) with portal hypertension. Methods A retrospective analysis was performed for 102 patients who received TIPS in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2015 to August 2021, and these patients were divided into PBC group with 41 patients and viral hepatitis cirrhosis group with 81 patients. Related indicators were collected, including routine blood test results, liver and renal function, coagulation function, portal vein thrombosis, hepatic encephalopathy, and etiology of TIPS treatment shortly after admission, preoperative portal venous pressure, and stents used in surgery, and Child-Pugh score was calculated. Follow-up data were collected and analyzed, including postoperative upper gastrointestinal rebleeding, stent dysfunction, hepatic encephalopathy, and the data on survival and prognosis. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for survival difference analysis. Results In the PBC group and the viral hepatitis cirrhosis group, the median percentage of reduction in portal venous pressure after surgery was 33.00% and 35.00%, respectively, and there was no significant difference between the two groups ( P > 0.05). At the end of follow-up, there were no significant differences between the PBC group and the viral hepatitis cirrhosis group in stent dysfunction rate (14.63% vs 24.69%, χ 2 =1.642, P > 0.05), upper gastrointestinal rebleeding rate (17.07% vs 24.69%, χ 2 =0.917, P > 0.05), the incidence rate of overt hepatic encephalopathy (12.20% vs 7.41%, χ 2 =0.289, P > 0.05), and disease-specific death rate (14.63% vs 9.88%, χ 2 =0.229, P > 0.05). Conclusion For PBC patients with portal hypertension, TIPS can achieve the same efficacy as the treatment of portal hypertension caused by viral hepatitis cirrhosis and can also effectively reduce portal hypertension without increasing the incidence rate of complications and disease-specific death rate. Therefore, it is a safe and effective treatment method.
