Objective To investigate the correlation between traditional Chinese medicine(TCM)syndrome elements and risk factors in patients with type Ⅱ cardio-renal syndrome(CRS).Methods A retrospective analysis was conducted on the medical records of 116 patients with type Ⅱ CRS.The distribution of TCM syndrome elements was analyzed,and the correlation between the syndrome elements and risk factors of gender,age,smoking history,alcohol consumption history,coronary heart disease,hypertension,diabetes,and anemia were evaluated.Results(1)The analysis of syndrome elements of 116 patients with type Ⅱ CRS showed that the main disease-location elements were heart(96 cases,82.76%),lung(89 cases,76.72%),kidney(81 cases,69.83%),spleen(71 cases,61.21%),and liver(25 cases,21.56%);the main disease-nature elements were qi deficiency(113 cases,97.41%),blood deficiency(96 cases,82.76%),yang deficiency(95 cases,81.89%),phlegm(94 cases,81.03%),yin deficiency(90 cases,77.59%),dampness(61 cases,52.59%),water retention(55 cases,47.41%),and blood stasis(47 cases,40.52%).(2)The analysis of age groups of 116 patients with type Ⅱ CRS showed that the majority of the patients were middle-aged and elderly individuals over 60 years old,and the age groups covered＜60 years old(4 cases,3.45%),61-70 years old(10 cases,8.62%),71-80 years old(28 cases,24.14%),81-90 years old(64 cases,55.17%),and>90 years old(10 cases,8.62%).(3)The analysis of gender of 116 patients with type Ⅱ CRS showed that 46 cases(39.66%)were male,and 70 cases(60.34%)were female,the female outnumbering the male.(4)The exploration of correlation between TCM syndrome elements and risk factors with Logistic regression analysis showed that blood deficiency was positively correlated with alcohol consumption,hypertension,and anemia(P＜0.05 or P＜0.01),yang deficiency was positively correlated with anemia(P＜0.05),yin deficiency was positively correlated with smoking and diabetes(P＜0.05),dampness was positively correlated with smoking and anemia(P＜0.01),water retention was positively correlated with gender and protein abnormalities(P＜0.05 or P＜0.01),and blood stasis was positively correlated with hypertension(P＜0.05).Conclusion The illness of type Ⅱ CRS is located in the heart,involving the five organs,and is closely related to the lungs and kidneys.The general pathogenesis of type Ⅱ CRS is characterized by being deficiency of qi and yang in the root cause,and having the symptom manifestations of phlegm and blood stasis.In type Ⅱ CRS patients,men are more likely to suffer water retention,smokers are more likely to suffer yin deficiency and dampness,drinkers are more likely to suffer blood deficiency,individuals with hypertension are more likely to suffer blood deficiency and blood stasis,individuals with diabetes are more likely to suffer yin deficiency,individuals with anemia are more likely to suffer blood deficiency,yang deficiency and dampness,and individuals with protein abnormalities are more likely to suffer water retention.

Objective To investigate the correlation between salivary cystatin D level and salivary gland injury in patients with primary Sj?gren syndrome(pSS).Methods A total of 51 pSS patients admitted in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Xi'an Jiaotong University from September 1,2022 to June 30,2023,and 51 age-and gender-matched healthy individuals who took physical examination in the hospital during same period were enrolled in the study.The level of salivary cystatin D was detected,and the difference in the level between the 2 groups was compared using an independent-samples t test.Pearson correlation analysis was applied to analyze the correlation between salivary cystatin D and clinical parameters in the patients.Results The pSS patients had significantly lower cystatin D level than the healthy controls(206.55±108.11 vs 374.32±172.24 pg/mL,P＜0.01).The cystatin D level in the pSS patients was positively correlated with both static(r=0.433,P=0.002)and dynamic salivary flow rates(r=0.363,P=0.009).The patients with higher score of salivary gland ultrasonography(SGUS)had obviously lower cystatin D than those with lower SGUS score(parotid gland:160.75±85.56 vs 290.53±95.17 pg/mL,P＜0.01;submandibular gland:157.76±87.59 vs 276.25±97.06 pg/mL,P＜0.01).The cystatin D level was also negatively correlated with peripheral blood IL-6 level(r=-0.453,P=0.001)and CD4+T cell count(r=-0.396,P=0.005)in the pSS patients.Conclusion Salivary cystatin D level can be used as an indicator of salivary gland damage for pSS patients.

Objective To study the feasibility and results of laparoscopic surgery for cholelithiasis in elderly patients over 80 years old.Methods A retrospective study was conducted on 53 patients over 80 years old who underwent laparoscopic surgery for cholelithiasis from January 2015 to April 2017.Results The operation was successfully carried out on 53 patients.The intraoperative blood loss was 5 ～ 300 ml.The operation time was (93.5 ±41.2) minutes and the postoperative hospital stay was (11.0 ± 3.7) days.Postperative complications included bile leakage (n =5),intra-abdominal infection (n =1),pulmonary infection (n =5),wound seroma (n =2).There were no perioperative deaths.Conclusion Laparoscopic surgery for cholelithiasis was safe and efficacious in elderly patients over 80 years old.
