Liver blood flow was measured in normal & CCl4-intoxicated mice & rats, using the electrolysis-generated hydrogen gas method. The results showed that the intramuscular injection of 6-15/kg of ISM increased significantly the liver blood flow in normal mice & rats. In acute or chronic CCl4-intoxicated mice & rats, the liver blood was decreased but the blood flow was restored the normal level by the ISM. In addition, the protective effect against liver injury was also observed by the histological examination & electron micrographs.The above results suggest that the protective effect of ISM against CCl4-induced liver injury seems to be through increasing the liver blood flow, improving liver's microcirculation & preventing or mitgating the denaturing or necrosis of liver cells.

Objective To explore the relationship between traditional Chinese medicine (TCM) syndromes of state of evil domination and clinical and laboratory indicators of IgA nephropathy. Methods A prospective study was used to collect data on clinical and laboratory examination of IgA nephropathy in multi clinical centers. Patients’ TCM syndrome types were determined according to the national diagnostic criteria at the same time. Totally 266 patients with IgA nephropathy were included in the study to establish a database for analyzing the relationship between TCM syndrome of state of evil domination and clinical and laboratory indicators. Results In the relationship between syndromes of state of evil domination distribution and clinical subtypes, patients of wind-heat syndrome had more macroscopic hematuria;patients of phlegm-damp syndrome had more nephrotic syndrome;patients of damp-heat syndrome had more chronic nephritis type Ⅰ;patients of blood stasis syndrome had more chronic nephritis type Ⅱ. In the relationship between syndrome of state of evil domination distribution and clinical manifestation, the incidence of hypertension was higher in patients of blood stasis syndrome than in other three types. It was more serious for hematuresis in the patients of wind-heat syndrome. For patients of phlegm-damp syndrome, the incidence of heave proteinuria was highest. In the relationship between syndrome of state of evil domination distribution and laboratory examination, 24-hour urinary protein quantification was higher than in patients of wind-heat and damp-heat syndrome, but the level of blood albumin was lowest. For patients of blood stasis syndrome, serum creatinine level was significantly higher than in other three types;the level of eGFR was just the opposite. The levels of blood cholesterol and triglyceride in patients of phlegm-damp syndrome were higher than in other three types. The activated partial thromboplastin time (APTT) levels in patients of blood stasis and phlegm-damp syndrome were lower than in other patients, but the FIB level was the exact opposite of APTT. In the relationship between syndrome of state of evil domination distribution and the stages of chronic kidney disease (CKD), patients of wind-heat syndrome were more in the first stage of CKD;patients of blood stasis syndrome were more in the third stage of CKD. Conclusion There is relative correlation between TCM syndromes of state of evil domination and clinical and laboratory indicators in IgA nephropathy, which would provide some reference to narrow the gap in the information of the four methods of TCM with clinical and laboratory indicators to enhance accurate diagnosis of TCM syndrome.

Objective:To construct the evaluation index system of peritoneal dialysis nursing quality, so as to provide a basis for management and evaluation of peritoneal dialysis nursing quality.Methods:Through literature review and expert interviews, the peritoneal dialysis nursing quality evaluation index system (draft) was initially determined on the evidence-based basis. The expert letter questionnaire was designed, and indexes of nursing quality evaluation were screened and revised by Delphi expert letter questionnaire and boundary value method. The analytic hierarchy process was used to determine the weight of evaluation indexes, and the evaluation system of the peritoneal dialysis nursing quality index was established.Results:The expert response rates of 2 rounds of questionnaires were 91.43% and 85.71%, and the expert authority coefficients of the 2 rounds were respectively 0.838 0 and 0.862 2, and the coordination coefficients of the first, second and third levels of indexes of the second round were respectively 0.643, 0.431 and 0.283 ( P<0.01) . The final evaluation index system included 3 first-level indicators, 18 second-level indicators and 84 third-level indicators. Conclusions:The evaluation index system of peritoneal dialysis nursing quality has good reliability and applicability. After further verification, it can be used as an evaluation tool of peritoneal dialysis nursing quality management.

Objective:To explore the risk factors for postoperative delirium in colorectal cancer patients based on Meta-analysis.Methods:A computer search was conducted on PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP and China Biology Medicine disc, and literatures on influencing factors of postoperative delirium of colorectal cancer published by each database until April 6, 2022 were selected. Two researchers independently screened the literature, extracted the data, and evaluated the quality of the literature using Newcastle-Ottawa Scale (NOS) . Stata 15.0 statistical software was used to conduct a Meta-analysis of the included literatures.Results:A total of 19 articles were included, including 5 295 patients. The Meta-analysis results showed that the combined odds ratio ( OR) values and 95% confidence interval (95% CI) of various factors for postoperative delirium in colorectal cancer patients were advanced age [1.10 (1.06-1.14) ] , male [2.29 (1.81-4.44) ] , alcohol abuse [3.14 (1.63-6.06) ] , preoperative physical condition grading (≥level 3) [1.47 (1.13-1.91) ] , comorbidities [1.59 (1.16-2.17) ] , history of mental illness [7.86 (4.57-13.54) ] , history of cerebrovascular disease [5.74 (3.78-8.72) ] , cognitive impairment [3.31 (1.20-9.08) ] , albumin [0.81 (0.66-0.99) ] , perioperative blood transfusion [2.29 (1.41-3.69) ] and C-reactive protein [2.24 (1.11-4.53) ] , all P<0.05. Conclusions:The risk factors for delirium in colorectal cancer patients after operation are old age, male, alcoholism, preoperative physical condition grading≥level 3, combined diabetes and other basic diseases, history of mental disease, history of cerebrovascular disease, cognitive dysfunction, low albumin, perioperative blood transfusion and elevated C-reactive protein.

Objective To study the correlation between pterygium area and the clinical manifestation and signs of primary pterygium obtained from OCULUS Keratograph. Methods A prospective case observation study was performed. Thirty.nine ( 55 eyes ) primary pterygium patients were selected from June to September 2016 in Zhongshan People's Hospital. The area of the pterygium invaded cornea and duration of pterygium were recorded. The ocular surface condition was detected by corneal fluorescein staining. The break up time of tear film ( BUT) and the gland function score were measured with OCULUS Keratograph. This study was approved by the Ethics Committee of Zhongshan People's Hospital ( 2015 [ 13 ] ) . All operations followed the Helsinki Declaration and all patients signed informed consent forms. Results The areas of pterygium invaded cornea was 2-20 mm2,the mean size was 5(3, 10)mm2;the duration of pterygium was 3-8 years,the mean duration was 5(4,6)years;the BUT was 2. 1-15. 0 seconds,the mean BUT was (6. 3±3. 0) seconds. The mean gland function score was 2(1,3). The area of pterygium was not significantly correlated with the duration of pteryguim (r=0.197,P=0.148),while it was negatively correlated with BUT (r=-0. 711, P<0. 001 ) and positively correlated with the tarsal gland score (r=0. 554,P<0. 001). What's more,82％ (45/55 eyes) of the patients' tear film rupture appeared firstly near pterygium's head. Conclusion OCULUS Keratograph can directly evaluate the ocular surface condition of pterygium patients in a non. contact and non.invasive method. Assessing the ocular surface damage by observing the area of pterygium invaded cornea may provide a prospective treatment for pterygium patients.
