Objective To investigate the clinical efficacy of Zusanli moxibustion intervention in abdominal distention with enteral nutrition after stomach cancer surgery.Methods One hundred patients who had undergone stomach cancer surgery and received postoperative enteral nutrition were randomly allocated to treatment and control groups, 50 cases each. The control group received medication and the treatment group, Zusanli moxibustion in addition. Post-treatment incidences and grading scores of abdominal distention were compared between the two groups.Results The incidence of abdominal distention was 6.0% in the treatment group and 24.0% in the control group; there was a statistically significant difference between the two groups (P<0.05). The grading score of abdominal distention was (0.33±0.58) in the treatment group and (0.92±1.00) in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Zusanli moxibustion can effectively prevent the occurrence of abdominal distention in patients with enteral nutrition after stomach cancer surgery.

Objective To investigate the expression and importance of basic fibroblast growth factor(bFGF)in renal tissue of doxorubicin-induced nephropathy rats,and discuss its possible role in minimal change nephrotic syndrome(MCNS).Methods Fifty male Wistar rats were enrolled in this study.They were randomly divided into normal group(n=10)and nephropathic group(n=40).The nephropathic group was established by a single intraperitoneal injection of doxorubicin 5 mg/kg.The rats of nephropathic group were killed on the 3rd,7th,14th and 28th day and 24 h urinary protein of all rats was measured.Normal group rats were killed on the 28th day.bFGF level in renal tissue was determined with immunohistochemistry assays,and was quantitatively analyzed with color image analysis system.The SPSS 10.0 software was used to obtain t-test of various groups and correlation analysis of 2 variables.Results 1.The 24 h urinary protein of nephropathy rats increased gradually on the 7th,14th and 28th day,and it was greatly higher than that in control group(Pa

Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0％ (21/21) and 95.2％ (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0％(23/23),0 and 45.1％(23/51).The corresponding values for MR were 91.3％(21/23),82.1％ (23/28) and 86.3％ (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P＜0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0％(42/42),42.9％(21/49) and 69.2％(63/91),respectively.The corresponding values for MRI were 95.2 ％(40/42),87.8％(43/49) and 91.2％(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P＜0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P＜0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

Objective: To evaluate the synergistic anticancer effects of the combination of apigenin (Api) and tanshinone Ⅱ A (Tan IIA), and investigate the mechanisms of pharmacological effects and their potential applications as an anticancer therapy in clinics. Methods: MTT assay were used to determine anticancer effects of the combination of Api and Tan ⅡA on BGC823, MCF7, and SMMC7721 cells. AV-PI dual stain and PI staining method were used for detecting the effect of the two drugs combination on BGC823 cell apoptosis and cell cycle. Expression of p53, BAX/BCL-2, cyclin B1 and D1 proteins were determined by Western blotting. Circular dichroism method and DNA melting point method were explored to detect interaction among the two drugs and DNA. S180 tumor xenograft mice model was used to evaluate the antitumor effects of the two drugs combination. Results: Tan IIA combined with Api exerted synergistic inhibitory effects on the proliferation of BGC823 and other tumor cells with the CI of 0.28. After tumor cell treated by combination of Tan IIA and Api, the tumor cell apoptosis was significantly enhanced and the value of BAX/BCL-2 in cells was up-regulated (P < 0.01); The levels of cyclin B1, D1 protein were changed and cell cycle arrest was increased which mainly blocked in S phase. The interaction among the two drugs and DNA was in two different ways, leading to the curves of thermal denaturation of DNA changed significantly. Furthermore, the combination of Tan IIA and Api showed a stronger inhibitory effect on tumor volume and weight in S180 mice model than monotherapy, which was similar to cyclophosphamide therapy but less side effects. Conclusion Tan IIA combined with Api exerted synergistic antitumor effects. The two drugs interacted with DNA in different ways and aggravated the cell cycle arrest, which were the key mechanisms of their synergistic antitumor effects.

Objective:To understand the comprehensive geriatric assessment (CGA) scores in chronic kidney disease (CKD) patients aged 65 years and older, and analyze the related influencing factors of quality of life.Methods:A total of 189 patients who were over 65 years old and diagnosed with CKD in the Department of Nephrology of Shanxi Provincial People's Hospital from October 2016 to October 2019 were included retrospectively. The patients were divided into dialysis group ( n=90 cases) and non-dialysis group ( n=99 cases) according to whether dialysis or not. The concise CGA scores included age, basic activities of daily living (BADL), instrumental activities of daily living (IADL), and modified cumulative illness rating score for geriatrics (MCIRS-G). Pearson correlation analysis was used to analyze the relationship between different scale scores and clinical indexes. Multiple linear regression analysis was used to further analyze independent related factors of the quality of life in elderly CKD patients. Results:Compared with the non-dialysis group, the BADL score and IADL score in the dialysis group were significantly reduced [(70.00±33.28) vs (93.38±14.32), t=6.166, P<0.001; (9.78±7.12) vs (15.95±5.74), t=6.520, P<0.001], while the MCIRS-G score was significantly increased [(31.13±4.00) vs (27.29±5.17), t=-5.741, P<0.001]. Linear regression analysis performed on the data of non-dialysis group patients showed that estimated glomerular filtration rate (eGFR), serum uric acid (SUA), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood potassium and chlorine were positively correlated with BADL and IADL scores (all P<0.05). B-type natriuretic peptide (BNP) was negatively correlated with BADL score ( P<0.01). BNP and age were negatively correlated with IADL score (both P<0.05). Fasting blood glucose (FBG) was positively correlated with MCIRS-G or MCIRS-G other than kidney (both P<0.05), and eGFR, SUA, total cholesterol, and HDL-C were negatively correlated with MCIRS-G or MCIRS-G other than kidney (all P<0.05). Multiple linear regression analysis showed that eGFR was an independent influencing factor for BADL ( P<0.01). Age and eGFR were independent influencing factors for IADL (both P<0.05). Conclusions:The decline of quality of life in elderly CKD patients is related with eGFR, SUA, age, BNP and HDL-C levels, and eGFR and age are independent influencing factors.

ObjectiveTo observe the effect of early rehabilitation on poststroke anxiety and depression.Methods137 stroke patients with hemiplegia were divided into the rehabilitation group (70 cases) and control group (67 cases). All patients in both two groups were given routine clinical treatment, but the patients in the rehabilitation group were given regular early rehabilitation. All patients were evaluated with Bathel Index (BI), Fugl-Meyer Motor Scale (FMMS), Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) before and 3 months after treatment.ResultsAfter 3 months treatment, the scores of HAMD, HAMA, BI and FMMS of patients in the rehabilitation group increased significantly compared with those before treatment ( P<0.05～0.01), and those in the control group ( P<0.05). The scores of BI and FMMS of patients in the control group after treatment also increased significantly compared with those before treatment ( P<0.05). The incidences of depression and anxiety of the rehabilitation group were 22.86% and 5.71%, those of the control group were 40.30% and 16.42%, there was a significant difference between two groups( P<0.05).ConclusionThe early rehabilitation can obviously decrease anxiety and depression of stroke patients with hemiplegia.
