Connotation of Traditional Chinese Medicine in Treatment of Chronic Obstructive Pulmonary Disease by Regulating Gut Microbiota Based on "Lung and Large Intestine Being Interior-exterior Related" / 中国实验方剂学杂志

Chronic obstructive pulmonary disease （COPD） is a heterogeneous lung condition characterized by persistent and often progressive airflow obstruction， including airway abnormalities （e.g.， bronchitis and bronchiolitis） and chronic respiratory symptoms （e.g.， dyspnea， cough， and expectoration）. It is one of the leading causes of death worldwide. According to the theory of traditional Chinese medicine （TCM）， the lung and large intestine are interior-exterior related. Therefore， COPD can be treated from both the lung and intestine by the methods of tonifying and invigorating lung， spleen， and kidney， dispelling phlegm， and expelling stasis. Gut microbiota plays a key role in human immunity， nerve， and metabolism and may act on COPD by affecting the structures and functions of lung and intestine tissue and regulating lung inflammation and immunity. TCM can restore the balance of gut microbiota， which is conducive to the recovery from COPD. For example， the treatment method of tonifying lung and invigorating kidney can regulate gut microbiota， alleviate pulmonary and intestinal injuries， and improve lung immunity. The treatment methods of dispelling phlegm and expelling stasis can regulate gut microbiota and reduce pulmonary inflammation. According to the TCM theory of lung and large intestine being interior-exterior related， this review elaborates on the connotation of TCM in the treatment of COPD by regulating gut microbiota， aiming to provide new ideas for the clinical treatment of COPD via gut microbiota.

Evaluation of alprostadil combined with different doses of mouse nerve growth factor in diabetic peripheral neuropathy / 中国医师进修杂志

Objective:To investigate the application of alprostadil combined with different doses of mouse nerve growth factor in diabetic peripheral neuropathy (DPN) and its effect on motor and sensory nerve conduction and inflammatory factors.Methods:One hundred and fiftypatients with DPN treated in Beihai People′s Hospital from June 2018 to March 2020 were randomly divided into low-dose group and high-dose group, with 75 cases in each group. On the basis of routine treatment, the low-dose group was given alprostadil + mouse nerve growth factor 18 μg/time, once a day. The high-dose group was given alprostadil+mouse nerve growth factor 30 μg/time, once a day, both two groups were treated for 3 weeks. The curative effect, motor and sensory nerve conduction velocity and inflammatory index tumor necrosis factor-α(TNF-α)interleukin-6 (IL-6), high sensitivity C-reactive protein (hs-CRP), white blood cell count (WBC) and cost-effectiveness analysis, adverse reactions between the two groups were compared.Results:There was no significant difference in the total effective rate between the low dose group and the high dose group ( P>0.05). After 1 and 3 weeks of treatment, the levels ofmotor and sensory nerve conduction velocity and TNF-α, IL-6, hs-CRP and WBC in the two groups has no significant differences ( P>0.05). The cost of each unit effect in the low-dose group was 43.11 Yuan, and the cost of each unit effect in the high-dose group was 57.58 Yuan. The high-dose group was higher than that in the low-dose group, and the high-dose group paid 572.56 Yuan more than the low-dose group for each additional unit effect. There was no significant difference in the total incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Alprostadil combined with 18 μg mouse nerve growth factor in the treatment of DPN has a similar improvement effect on clinical symptoms, motor and sensory nerve conduction and inflammatory factors, and has advantages in cost-effectiveness.

Role of traditional Chinese medicine in treatment of chronic hepatitis B by nucleos(t)ide analogues / 临床肝胆病杂志

Nucleos(t)ide analogues (NUC) can inhibit the replication of hepatitis B virus (HBV) and effectively treat chronic hepatitis B (CHB), but they cannot completely eradicate HBV and cannot prevent the progression to hepatitis B cirrhosis and liver cancer in the context of a low viral load. In recent years, traditional Chinese medicine has been widely used in the treatment of CHB. This article elaborates on the application and mechanism of traditional Chinese medicine in inhibiting HBV replication, reducing the content of HBeAg, and delaying the progression to hepatitis B cirrhosis, and it is proposed that traditional Chinese medicine can improve the therapeutic effect of NUC in the treatment of CHB.

Value of five noninvasive diagnostic methods for liver cirrhosis in diagnosis of traditional Chinese medicine syndrome types in patients with compensated hepatitis B cirrhosis / 临床肝胆病杂志

Objective To investigate the association of five noninvasive diagnostic methods for liver cirrhosis, i.e., liver stiffness measurement (LSM) on FibroScan, aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 (FIB-4), gamma-glutamyl transpeptidase-to-platelet ratio (GPR), and red blood cell distribution width-to-platelet ratio (RPR), with traditional Chinese medicine (TCM) syndrome types in patients with compensated hepatitis B cirrhosis. Methods A retrospective analysis was performed for the clinical data of 327 patients who were diagnosed with compensated hepatitis B cirrhosis in The First Affiliated Hospital of Henan University of Chinese Medicine from January 2017 to January 2020, and based on their TCM syndrome type, they were divided into liver depression and spleen deficiency group with 160 patients, liver-gallbladder damp-heat syndrome group with 84 patients, liver-kidney Yin deficiency group with 13 patients, spleen-kidney Yang deficiency group with 5 patients, and blood stasis obstructing the collaterals group with 65 patients. Related data were collected, including clinical data, routine blood test results, liver function, LSM, and color Doppler ultrasound findings of liver, gallbladder, spleen, and pancreas. TCM syndrome differentiation was performed, and the models of APRI, FIB-4, GPR, and RPR were established. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups; the multiple independent samples Kruskal-Wallis H rank sum test was used for comparison of non-normally distributed continuous data between multiple groups, and the one- way Kruskal-Wallis ANOVA (k-sample) was used for multiple comparison; the binary logistic regression analysis was used to investigate the association between TCM syndrome types and non-invasive diagnosis of liver cirrhosis; the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic capability of five noninvasive methods for predicting TCM syndrome type in compensated hepatitis B cirrhosis. Results The logistic regression analysis showed that in the liver-gallbladder damp-heat syndrome group, aspartate aminotransferase OR =1.981, 95% CI : 1.8225-2.139, P < 0.05), and LSM ( OR =2.002, 95% CI : 1.840-2.160, P < 0.05) were influencing factors for compensated hepatitis B cirrhosis; in the liver depression and spleen deficiency group, portal vein width ( OR =4.402, 95% CI : 4.050-4.754, P < 0.05), LSM ( OR =3.901, 95% CI : 3.589-4.213, P < 0.05), APRI ( OR =1.891, 95% CI : 1.740-2.042, P < 0.05), and FIB-4 ( OR =1.845, 95% CI : 1.697-1.993, P < 0.05) were influencing factors for compensated hepatitis B cirrhosis; in the blood stasis obstructing the collaterals group, LSM ( OR =2.465, 95% CI : 2.268-2.662, P < 0.05), APRI ( OR =1.298, 95% CI : 1.194-1.402, P < 0.05), and FIB-4 ( OR =1.849, 95% CI : 1.701-1.997, P < 0.05) were influencing factors for compensated hepatitis B cirrhosis. The ROC curve analysis showed that LSM and RPR had a significantly better diagnostic value than the other methods in evaluating liver-gallbladder damp-heat syndrome, and LSM and FIB-4 had a significantly better diagnostic value than the other methods in evaluating liver depression and spleen deficiency; all five noninvasive diagnostic methods had a good value in evaluating the syndrome of blood stasis obstructing the collaterals. Conclusion The five noninvasive diagnostic methods have their own advantages in evaluating different syndrome types, which provide a reference for the diagnosis of TCM syndrome types in patients with compensated hepatitis B cirrhosis.

Performance of controlled attenuation parameter measured by FibroScan in the diagnosis of nonalcoholic fatty liver disease and its association with traditional Chinese medicine syndrome types / 临床肝胆病杂志

Objective To investigate the application value of controlled attenuation parameter (CAP) of hepatocyte steatosis measured by FibroScan in the diagnosis and traditional Chinese medicine (TCM) syndrome differentiation of nonalcoholic fatty liver disease (NAFLD). Methods A retrospective analysis was performed for related data of 364 patients with NAFLD who attended The First Affiliated Hospital of Henan University of Traditional Chinese Medicine from January 2017 to December 2019, including basic information (age, sex, and body mass index [BMI]), CAP measured by FibroScan, ultrasound findings of the liver, gallbladder, spleen, and pancreas, liver function parameters, and blood lipid parameters. TCM syndrome differentiation was performed based on the information obtained by four diagnostic methods, and then the patients were divided into liver depression and spleen deficiency group, damp turbidity and stagnation group, damp-heat accumulation group, intermingled phlegm and blood stasis group, and spleen-kidney deficiency group. The association of CAP, color Doppler ultrasound findings, liver function parameters, blood lipid parameters, and BMI with TCM syndrome was analyzed. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups; the Kruskal-Wallis H rank sum test with multiple sets of independent samples was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. The chi-square test or Kruskal-Wallis H rank sum test was used for comparison of categorical data between multiple groups and further comparison between two groups. A Spearman's rank correlation analysis was used to investigate the correlation between CAP and ultrasound grading. Results Among the 364 patients with NAFLD, 169 had the syndrome of liver depression and spleen deficiency, 71 had the syndrome of damp turbidity and stagnation, 60 had the syndrome of damp-heat accumulation, 41 had the syndrome of intermingled phlegm and blood stasis, and 23 had the syndrome of spleen-kidney deficiency. There was a significant difference in CAP value between the different syndrome types ( F =14.839, P < 0.001), and further comparison between two groups showed that the spleen-kidney deficiency group and the intermingled phlegm and blood stasis group had a significantly higher CAP value than the liver depression and spleen deficiency group, the damp turbidity and stagnation group, and the damp-heat accumulation group (all P < 0.05). There was a significant difference in ultrasound grading between the different syndrome types ( χ 2 =22.947, P < 0.001); the liver depression and spleen deficiency group mainly had a mild grade (40.2%), the damp turbidity and stagnation group and the damp-heat accumulation group mainly had a moderate grade (53.5% and 53.3%, respectively), and the intermingled phlegm and blood stasis group and the spleen-kidney deficiency group mainly had a severe grade (68.3% and 43.5%, respectively). CAP was positively correlated with the severity of fatty liver ( r =0.431, P < 0.001). The spleen-kidney deficiency group and the intermingled phlegm and blood stasis group had significantly higher levels of alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, and BMI than the other three groups (all P < 0.001). Conclusion Association is observed between CAP and the TCM syndrome types of NAFLD, and patients with the syndrome of spleen-kidney deficiency and the syndrome of intermingled phlegm and blood stasis have a higher CAP value than those with the other syndrome types. CAP has similar efficiency to color Doppler ultrasound in the diagnosis of NAFLD.
