To explore the correlation between the changes of the intestinal flora of newly treated pulmonary tuberculosis patients and the immune indicators of the body, and to provide a reference for the prevention and treatment of pulmonary tuberculosis. A single-center and case-control study was adopted. From October 2020 to April 2021, 43 patients with newly diagnosed tuberculosis in the Department of Tuberculosis, Affiliated Changsha Central Hospital,University of South China were selected as the control group. 43 cases of newly treated pulmonary tuberculosis (PTB), 43 healthy control (HC) during the same period, collected fresh feces and whole blood of subjects, and used Illumina Hiseq high-throughput sequencing technology to analyze 16S of all microorganisms in feces The V4 region of rRNA was amplified and sequenced, and the structure of the intestinal flora was analyzed by QIIME software. Use flow cytometry to determine the subject′s immune indicators (CD3 +, CD4 +, CD8 +, CD4 +CD25 +CD127 -Treg, CD14 +CD16 +, CD14 +CD16 -), and analyze the changes in intestinal flora and immune function in newly treated pulmonary tuberculosis patients Inherent connection. The χ2 test, t test, and Wilcox rank sum test were used to analyze the differences in age, gender, α diversity, and relative abundance of the two groups of people. Compared with the HC group, the alpha diversity of the intestinal flora in the PTB group decreased (shannon index: t=3.906, P=0.000 2; simpson index: Z=553, P=0.004 7; chao1 index: t=5.395, P=0.000 0). β diversity analysis showed that there were significant differences in the structure of the intestinal flora between the two groups ( P=0.000). Species difference analysis showed that at the phylum level, the relative abundance of Firmicutes in the PTB group was significantly lower than that in the HC group ( Z=486.0, P=0.000 5). At the genus level, there are 15 different bacterial genera between the two groups. In the PTB group, bifidobacterium, enterococcus, lactobacillus, anaerostipes, the relative abundance of the above 5 genera of veillonella is higher than that of the HC group ( P<0.05); Butyricimonas, clostridium, and broutella (blautia), coprococcus, dorea, lachnospira, roseburia, faecalibacterium, ruminococcus, the relative abundance of 10 bacterial genera including dialister was lower than that of the HC group ( P<0.05). Comparison of immune indexes between groups showed that CD14 +CD16 +monocytes (%) in the PTB group were higher than those in the HC group ( t=2.456, P=0.001 6<0.05), while CD14 +CD16 -monocytes (%) were lower than HC ( t=-4.368, P=0.000<0.05), while the differences in CD3 +, CD4 +, CD8 +, CD4 +/CD8 +and Treg (CD4 +CD25 +CD127 -) were not statistically significant ( P>0.05). Spearman correlation analysis showed that Firmicutes in the PTB group was negatively correlated with CD4 +/CD8 +, CD14 +CD16 +( r=-0.218, P=0.048; r=-0.245, P=0.025), and positively correlated with CD14 +CD16 -Correlation ( r=0.250, P=0.022); At the genus level, Faecalis is positively correlated with CD4 +/CD8 +and CD4 +( r=0.250, P=0.023; r=0.258, P=0.019); Rosella and CD3 +, CD8 +and CD14 +CD16 -are positively correlated ( r=0.27, P=0.024; r=0.219, P=0.046; r=0.027, P=0.039), and negatively correlated with CD14 +CD16 +( r=-0.280, P= 0.01). Changes in the structure of the intestinal flora of newly treated pulmonary tuberculosis patients may be one of the influencing factors of the immune function of the body. Targeted optimization of the structure of the intestinal flora and improvement of the body′s immunity may be used as an effective auxiliary treatment for pulmonary tuberculosis.

Huntington's disease (HD) is a deadly neurodegenerative disease with abnormal expansion of CAG repeats in the huntingtin gene. Mutant Huntingtin protein (mHTT) forms abnormal aggregates and intranuclear inclusions in specific neurons, resulting in cell death. Here, we tested the ability of a natural heat-shock protein 90 inhibitor, Gedunin, to degrade transfected mHTT in Neuro-2a cells and endogenous mHTT aggregates and intranuclear inclusions in both fibroblasts from HD patients and neurons derived from induced pluripotent stem cells from patients. Our data showed that Gedunin treatment degraded transfected mHTT in Neuro-2a cells, endogenous mHTT aggregates and intranuclear inclusions in fibroblasts from HD patients, and in neurons derived from induced pluripotent stem cells from patients in a dose- and time-dependent manner, and its activity depended on the proteasomal pathway rather than the autophagy route. These findings also showed that although Gedunin degraded abnormal mHTT aggregates and intranuclear inclusions in cells from HD patient, it did not affect normal cells, thus providing a new perspective for using Gedunin to treat HD.

Objective To investigate the clinical features,diagnosis,treatment,and prognosis of patients with liver injury caused by Periploca forrestii Schltr.Methods A retrospective analysis was performed for the general data,clinical manifestations,and laboratory examinations of 22 patients who were diagnosed with liver injury caused by Periploca forrestii Schltr.from November 2014 to December 2015,and their clinical type was determined according to the classification criteria of drug-induced liver injury recommended by the Council for Intemational Organizations of Medical Sciences.Results There were 12 female and 10 male patients.The mean medication time ranged from 1 week to 2 months,and as for biochemical markers,there were mainly abnormalities in alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TBil),alkaline phosphatase (ALP),and gamma-glutamyl transpeptidase (GGT).ALT and AST increased in all the patients,with mean levels of 676.68±481.11 U/L and 527.36±361.14 U/L,respectively;TBil increased to a mean level of 170.26±147.30 μmol/L in 19 patients;ALP increased to a mean level of 135.61±59.26 U/L in 13 patients;GGT increased to a mean level of 195.65±138.48 U/L in 20 patients.As for clinical typing,18 patients had liver cell injury,none had cholestasis,3 had a mixed type,and 1 had an unclassified type.One patient died and all the other patients fully recovered.Conclusion Periploca forrestii Schltr.had complex constituents,and liver injury caused by this drug is mainly liver cell injury.The pathogenesis of liver injury caused by Periploca forrestii Schltr.is presumed to be related to patients' idiosyncratic reaction to its constituents.

ObjectiveTo compare the therapeutic efficacy between warm needling and Western medication in treating chronic atrophic gastritis.MethodSixty patients were randomized into an observation group and a control group, 30 cases in each group. The observation group was intervened by warm needling, selecting Guanyuan (CV4), Qihai (CV6), Zusanli (ST36), Xuehai (SP10), and Geshu (BL17); The control group was by Western medication, including Omeprazole, Amoxillin, Metronidazole, etc. The clinical efficacies were compared after 8-week treatment. Besides, gastroscopewas ordered at outset and after 8-week treatment to compare the therapeutic efficacies.ResultIn comparing the clinical symptoms, the total effective rate was 93.3% in the observation group versus 70.0% in the control group (P<0.05); the gastroscope scores dropped significantly in both groups after 8-week treatment (P<0.05), and the score of the observation group was significantly lower than that of the control group (P<0.05). ConclusionAcupuncture-moxibustion can significantly improve the clinical symptoms and gastroscopic results in patients with chronic gastritis, and its therapeutic efficacy is superior to that of Western medication.

Objective To observe the efficacy difference between nerve-trunk stimulation plus electroacupuncture at antagonistic points and the control group. Method Patients were randomized into group A (nerve-trunk stimulation plus electroacupuncture at antagonistic points), group B (electroacupuncture at antagonistic points), and group C (basic treatment), 45 cases in each group. The interventions were given once a day, 5 times a week, totally for 4 weeks. The changes of spasm degree and motor function of upper limb and activities of daily life were observed. Result After intervention, there were significant differences between group B and group C, and between group A and group B (P<0.05); there was a significant difference between group A and group C (P<0.01). Conclusion Compared to the control group, nerve-trunk stimulation plus electroacupuncture at antagonistic points can produce more significant efficacies in improving the spasm degree and motor function of upper limb and activities of daily life.

Objective To evaluate the clinic value of multiple tumor markers plus PSA in diagnosing prostate cancer.Methods We collected serum samples of 140 prostate cancer patients with average age of 68 (48-82) years,104 benign prostate hyperplasia patients with average age of 70 (52-87) years,and 162 healthy people with average age of 38 (23-49) years.We had detected PSA levels and also the protein expressions of XAGE-1b,SSX-2,AM ACR and AKAP4.In healthy people,the ranges of the normal values with 95％ data range were determined.Multiple tumor markers and PSA were calculated their positive rate,specificity and sensitivity in diagnosing prostate cancer.We had randomly chosen one positive serum,and analyzed the 4 protein expressions by Western bolt.We detected the serum with the four markers plus PSA by Luminex medthod,then drew ROC curve and calculated AUC area according to the results.Results Among all those samples,PSA levels of 266 samples were under 4tμg/L,86 samples were between 4-10 μg/L,and 54 samples were above 10 μg/L.The positive rates of XAGE-1b,SSX-2,AMACR and AKAP4 in prostate cancer patients were 53.6％ (75/140),34.3％ (48/140),27.9％ (39/140),44.3％ (62/140) respectively.The AUC of XAGE-1b,SSX-2,AMACR,AKAP4 and PSA were 0.666,0.615,0.551,0.768,0.675 respectively.The AUC of their combination was 0.887; The specificity and sensitivity of single PSA detection and combination detection were 60.0％,46.2％ and 80.0％,82.2％.Among those whose PSA value was between 4-10 μg/L,the AUC of single PSA detection was 0.505,the specificity and sensitivity of single PSA detection were 43.2％ and 31.8％; the AUC of the combination detection was 0.803; their specificity and sensitivity were 83.7％ and 73.2％.Conclusions Compared with the single PSA detection,the combination of XAGE-1b,SSX-2,AMACR,AKAP4 and PSA has been greatly improved the specificity and sensitivity in prostate cancer detection.This tool still has significant value even in patients with PSA value between 4-10 μg/L.

Objective Our preliminary study demonstrates that quercetin can inhibit the proliferation of HL-60 cells. This sudy aimed to find some drugs which could have synergistic effects with quercetin on apoptosis of HL-60 cells. Methods HL-60 cells were cultured with bortezomib at different concentrations (1, 2, 4, 8, 16, and 32μmol/L) alone or combined with quercetin at different concentrations for 48 h. HL-60 cells were cultured with lenalidomide at different concentrations (5, 10, 20, 40, 80, 160, and 320 μmol/L) alone or in combination with quercetin at different concentrations for 48 h. The CCK-8 assay was used to determine the effects on proliferation of HL-60 cells. Results Bortezomib significantly inhibited the proliferation of HL-60 cells (P<0.01). IC50 of quercetin was 49.24μmol/L after cells treated by quercetin combined with bortezomib, which was 13.44μmol/L lower than that treated by quercetin alone. Isobolographic analysis revealed the two drugs had synergistic effect. The results of cell viability of HL-60 cells treated by lenalidomide at lower concentrations (5, 10, 20, 40, and 80μmol/L)were not different from those of the control group (P > 0.05). The results of cell viability of HL-60 cells treated by lenalidomide at higher concentrations (160 and 320μmol/L) were lower than those of the control group (P<0.05). IC50 of quercetin after cells treated by quercetin combined with bortezomib was not different from that treated by quercetin alone. Isobolographic analysis revealed the two drugs had no synergistic effect. Conclusions Bortezomib can inhibit the proliferation of HL-60 cells and it has a synergistic effect with quercetin on HL-60 cells. Lenalidomide has a weaker role in inhibition of the proliferation of HL-60 cells, and it has no synergistic effect with quercetin on HL-60 cells.
