Relationship between Bacteria in the Lower Respiratory Tract/Lung Cancer and the Development of Lung Cancer as well as Its Clinical Application / 中国肺癌杂志

Due to the advancement of 16S rRNA sequencing technology, the lower respiratory tract microbiota, which was considered non-existent, has been revealed. The correlation between these microorganisms and diseases such as tumor has been a hot topic in recent years. As the bacteria in the surrounding can infiltrate the tumors, researchers have also begun to pay attention to the biological behavior of tumor bacteria and their interaction with tumors. In this review, we present the characteristic of the lower respiratory tract bacteria and summarize recent research findings on the relationship between these microbiota and lung cancer. On top of that, we also summarize the basic feature of bacteria in tumors and focus on the characteristic of the bacteria in lung cancer. The relationship between bacteria in lung cancer and tumor development is also been discussed. Finally, we review the potential clinical applications of bacterial communities in the lower respiratory tract and lung cancer, and summarize key points of sample collection, sequencing, and contamination control, hoping to provide new ideas for the screening and treatment of tumors.

Obstacles and approaches for the implementation of external long-term prescription dispensing for chronic diseases / 中国药房

The policy of long-term prescription for chronic diseases in China is gradually being improved and implemented， and external long-term prescription dispensing is being encouraged. The long-term prescription policy runs through the links of drug supply， equipment， use and policy， involving government departments such as medical security and health， as well as stakeholders such as patients， medical institutions and designated detail pharmacies. There are still some problems in the external dispensing of long-term prescriptions， such as the disunity of drug catalogue and the need for coordination among regulatory parties in the policy link； the need to improve the participation enthusiasm and service ability in the equipment link； the increased difficulty of prescription management， the need to improve the circulation platform in the use link. The promotion of external long-term prescription policy requires health insurance， medical service， and the medicine industry co-development， multi-party participation， and policy coordination. Among them， the “dual channel” policy， the policy of centralized medicine procurement， and the pharmacy included in outpatient overall management policy have all played a positive role in promoting the implementation of external long-term prescription dispensing for chronic diseases. It is necessary to improve supporting policies and implement regulatory responsibilities in the policy link， promote drug classification and service capabilities in the equipment link， improve the electronic prescription circulation platform， and strengthen prescription management in use link， so as to promote the implementation of external long-term prescription dispensing.

Objective:To investigate the effect of early interventional therapy with fiberoptic bronchoscope in patients with inflammatory infiltrating type (Ⅰ type) tracheobronchial tuberculosis (TBTB).Methods:Using prospective research methods, 306 patients with Ⅰ type TBTB diagnosed by fiberoptic bronchoscopy in the Third People′s Hospital of Kunming City from January 2019 to April 2022 were selected. The patients were divided into observation group and control group according to the random number table method with 153 cases each. The patients in control group were given routine anti-tuberculosis chemotherapy, and the patients in observation group were given routine anti-tuberculosis chemotherapy combined with early interventional therapy with fiberoptic bronchoscope. Sputum smear examination and tuberculosis culture were performed at the end of 1, 3 and 6 months of treatment, and the negative conversion of sputum culture was recorded. Chest X-ray, pulmonary function and fiberoptic bronchoscope were performed at the end of 1, 3 and 6 months of treatment to evaluate the improvement rate of clinical symptoms, effective absorption rate of lesions and effective absorption rate of obstructive pneumonia. The CD 4+, CD 8+, CD 4+/CD 8+, interferon γ (IFN-γ), interleukin-6 (IL-6) and C reactive protein (CRP) before and after treatment were detected. The random walking model of immune inflammation was evaluated. Results:The sputum negative conversion rates at the end of 1, 3 and 6 months of treatment in observation group were significantly higher than those in control group: 64.71%(99/153) vs. 52.29%(80/153), 80.39%(123/153) vs. 62.09%(95/153) and 91.50%(140/153) vs. 73.86%(113/153), and there were statistical differences ( P<0.05 or <0.01). The improvement rate of clinical symptoms at the end of 1 month of treatment in observation group was significantly higher than that in control group: 94.77%(145/153) vs. 66.67%(102/153), and there was statistical difference ( P<0.01); the clinical symptoms disappeared in both groups at the end of 3 and 6 months of treatment. The effective absorption rates of lesions at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 73.20%(112/153) vs. 51.63%(79/153) and 96.73%(148/153) vs. 85.62%(131/153), and there were statistical differences ( P<0.01); all the lesions were absorbed at the end of 6 months of treatment in both groups. The effective absorption rates of obstructive pneumonia at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 78.43% (120/153) vs. 39.87%(61/153) and 89.54%(137/153) vs. 79.08%(121/153), and there were statistical differences ( P<0.01 or <0.05); all obstructive pneumonia were absorbed at the end of 6 months of treatment in both groups. There were no statistical differences in CD 4+, CD 8+, CD 4+/CD 8+, IL-6, IFN-γ and CRP before treatment between the two groups ( P>0.05); the CD 4+, CD 4+/CD 8+ and IFN-γ after treatment in observation group were significantly higher than those in control group: 0.343 ± 0.032 vs. 0.311 ± 0.023, 1.37 ± 0.18 vs. 1.12 ± 0.16 and (38.47 ± 3.50) ng/L vs. (20.52 ± 2.96) ng/L, the CD 8+, IL-6 and CRP were significantly lower than those in control group: 0.251 ± 0.020 vs. 0.268 ± 0.021, (19.40 ± 3.31) ng/L vs. (34.58 ± 5.82) ng/L and (10.41 ± 2.87) mg/L vs. (17.47 ± 3.14) mg/L, and there were statistical differences ( P<0.01). The evaluation results of random walking model showed that CD 4+, CD 8+, CD 4+/CD 8+, IFN-γ, IL-6 and CRP in the observation group were better than those in the control group in the maximum random fluctuation, number of walking steps, positive walking growth rate, random fluctuation power law value, comprehensive improvement rate, recording times of comprehensive evaluation index and expected improvement value. Conclusions:Early interventional therapy with fiberoptic bronchoscope can effectively assist systemic drug therapy in patients with Ⅰ type TBTB, which can accelerate focus absorption, promote sputum negative conversion, enhance cellular immunity and effectively inhibit inflammatory reaction.

Advances in the treatment of Alport syndrome / 国际儿科学杂志

Alport syndrome(AS)is a hereditary nephropathy associated with hematuria, proteinuria and progressive kidney failure.It is characterized by a defective glomerular basement membrane caused by mutations in type Ⅳ collagen genes COL4A3/A4/A5, which result in defective in the type Ⅳa3, a4 and a5 chains respectively.At present, there is no preventive or curative therapies for AS.Inhibitors of the renin angiotensin aldosterone system are routinely used to slow the progression of kidney disease and prolong life expectancy.Ramipril was found in retrospective studies to delay the onset of end stage renal disease(ESRD), supporting that early initiation of renin angiotensin aldosterone system blockade is very important.Advances in our understanding on the pathogenesis of AS has culminated in the development of innovative therapeutic approaches that are currently under investigation.This review will briefly outline novel therapeutic targets for the prevention of renal disease progression in AS.

Risk factors of new-onset hypertriglyceridemia in kidney transplant recipients: a single-center analysis / 器官移植

Objective To identify the risk factors of new-onset hypertriglyceridemia (HTG) in kidney transplant recipients. Methods Clinical data of 149 kidney transplant recipients were retrospectively analyzed. According to serum triglyceride (TG) level after operation, they were divided into the non-HTG group (TG≤1.7 mmol/L, n=60) and new-onset HTG group (TG>1.7 mmol/L, n=89). Baseline data of all recipients were compared between two groups. The risk factors of HTG in kidney transplant recipients were analyzed by generalized estimating equation (GEE), and validated by multiple regression equations. Results No significant differences were observed in baseline data between two groups (all P>0.05). Multivariate analysis showed that the incidence of HTG in the middle and high tacrolimus (Tac) concentration groups was higher than that in the low Tac concentration group [odds ratio (OR) 3.11, 95% confidence interval (CI) 1.22-7.93, P=0.018 in the middle Tac concentration group; OR 5.11, 95%CI 1.31-19.98, P=0.019 in the high Tac concentration group]. Compared with type-A blood recipients, the risk of new-onset HTG was significantly increased in type-O blood counterparts (OR 2.77, 95%CI 1.14-6.71, P=0.024). The risk of new-onset HTG was decreased along with the increase of preoperative globulin level (OR 0.93, 95%CI 0.87-0.99, P=0.043). At postoperative 3 months, Tac blood concentration in the new-onset HTG group was significantly higher compared with that in the non-HTG group, and significant difference was observed (P<0.05). Multiple regression equations confirmed that the risk of new-onset HTG in type-O blood kidney transplant recipients was higher than that in type-A blood counterparts, and the risk of new-onset HTG in the middle and high Tac concentration groups was higher than that in the low Tac concentration group (all P<0.05). Conclusions Type-O blood kidney transplant recipients are more prone to HTG. It is necessary to strengthen postoperative monitoring and control of blood lipids. The blood concentration of Tac probably affects the new-onset HTG in kidney transplant recipients. Maintaining an appropriate blood concentration of Tac may be beneficial to lowering the risk of HTG.

A method for sensitivity analysis of deviation factor for geometric correction of cone-beam CT system / 南方医科大学学报

OBJECTIVE@#To propose a sensitivity test method for geometric correction position deviation of cone-beam CT systems.@*METHODS@#We proposed the definition of center deviation and its derivation. We analyzed the influence of the variation of the three-dimensional spatial center of the steel ball point, the projection center and the size of the steel ball point on the deviation of geometric parameters and the reconstructed image results by calculating the geometric correction parameters based on the Noo analytical method using the FDK reconstruction algorithm for image reconstruction.@*RESULTS@#The radius of the steel ball point was within 3 mm. The deviation of the center of the calibration parameter was within the order of magnitude and negligible. A 10% Gaussian perturbation of a single pixel in the 3D spatial coordinates of the steel ball point produced a deviation of about 3 pixel sizes, while the same Gaussian perturbation of the 2D projection coordinates of the steel ball point produced a deviation of about 2 pixel sizes.@*CONCLUSION@#The geometric correction is more sensitive to the deviation generated by the three-dimensional spatial coordinates of the steel ball point with limited sensitivity to the deviation generated by the two-dimensional projection coordinates of the steel ball point. The deviation sensitivity of a small diameter steel ball point can be ignored.

Recent Advances and Controversies in Minute Pulmonary Meningothelial-like Nodules / 中国肺癌杂志

Minute pulmonary meningothelial-like nodules (MPMNs) are benign small lesions in the lungs, with similar pathological characteristics to the meningeal epithelium. MPMNs have similar imaging manifestations to malignant tumors, which can lead to misdiagnosis in clinical practice. There is no consensus on the pathogenesis of MPMNs, with some suggest that MPMNs derive from reactive proliferation, while others suggest that MPMNs share a common origin and molecular mechanism with meningiomas in the central nervous system. Understanding the characteristics of MPMNs and studying their pathogenesis will help improve the understanding and diagnosis of MPMNs. In this article, we reviewed the clinical, pathological, imaging characteristics, differential diagnosis and pathogenesis of MPMNs. We also analyze the existing research advances regarding the pathogenesis and propose prospects for further research.

Exosomes secreted from human umbilical cord mesenchymal stem cells promote pancreatic ductal adenocarcinoma growth by transferring miRNAs / 中华肿瘤杂志

Objective: To observe the effects of exosomes derived from human umbilical cord mesenchymal stem cells on the proliferation and invasion of pancreatic cancer cells, and to analyze the contents of exosomes and explore the mechanisms affecting pancreatic cancer cells. Methods: Exosomes extracted from human umbilical cord mesenchymal stem cells were added to pancreatic cancer cells BxPC3, Panc-1 and mouse models of pancreatic cancer, respectively. The proliferative activity and invasion abilities of BxPC3 and Panc-1 cells were measured by cell counting kit-8 (CCK-8) and Transwell assays. The expressions of miRNAs in exosomes were detected by high-throughput sequencing. GO and KEGG were used to analyze the related functions and the main metabolic pathways of target genes with high expressions of miRNAs. Results: The results of CCK-8 cell proliferation assay showed that the absorbance of BxPC3 and Panc-1 cells in the hucMSCs-exo group was significantly higher than that in the control group [(4.68±0.09) vs. (3.68±0.01), P<0.05; (5.20±0.20) vs. (3.45±0.17), P<0.05]. Transwell test results showed that the number of invasion cells of BxPC3 and Panc-1 in hucMSCs-exo group was significantly higher than that in the control group (129.40±6.02) vs. (89.40±4.39), P<0.05; (134.40±7.02) vs. (97.00±6.08), P<0.05. In vivo experimental results showed that the tumor volume and weight in the exosomes derived from human umbilical cord mesenchymal stem cells (hucMSCs-exo) group were significantly greater than that in the control group [(884.57±59.70) mm(3) vs. (695.09±57.81) mm(3), P<0.05; (0.94±0.21) g vs. (0.60±0.13) g, P<0.05]. High-throughput sequencing results showed that miR-148a-3p, miR-100-5p, miR-143-3p, miR-21-5p and miR-92a-3p were highly expressed. GO and KEGG analysis showed that the target genes of these miRNAs were mainly involved in the regulation of glucosaldehylation, and the main metabolic pathways were ascorbic acid and aldehyde acid metabolism, which were closely related to the development of pancreatic cancer. Conclusion: Exosomes derived from human umbilical cord mesenchymal stem cells can promote the growth of pancreatic cancer cells and the mechanism is related to miRNAs that are highly expressed in exosomes.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine： Sjögren's Syndrome / 中国实验方剂学杂志

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

Screening of active ingredients for estrogenic effect of total flavonoids from Cuscutae Semen / 中国药房

OBJECTIVE To screen the active ingredient with estrogenic effect from total flavonoids of Cuscutae Semen. METHODS The estrogenic effect of total flavonoids from 10 batches of Cuscutae Semen was evaluated with mouse uterus coefficient and endometrial thickness as evaluation indexes， establish its fingerprint and calibrate the common peak. Common peak and spectrum-effect relationship of the above two indicators were analyzed by bivariate relationship analysis and grey correlation analysis to screen active components with estrogenic effect. UPLC-Q-TOF-MS technology was used to characterize the active components. RESULTS The estrogenic effect of total flavonoids from 10 batches of Cuscutae Semen was good. Twenty-eight and thirty-three common peaks of total flavonoids in Cuscutae Semen were obtained in the positive and negative ion modes respectively. The constituents represented by peaks 7，10，12-16，26 in positive ion mode and peaks 2，5，8，9，12，16，19，22-26 in negative ion mode were highly correlated with the estrogenic effect of total flavonoids from Cuscutae Semen. Further identification showed that the active substances with estrogenic effect from the total flavonoids of Cuscutae Semen were 5，7，3′， 4′-tetramethoxyflavone， 6- O-（trans） p-coumarin-furanfructose-（2→1）-glucopyranoside， rutin， kaempferol-3，7-diglucoside， apigenin-7-O-glucoside， hyperoside， baicalin， quercitin， quercetin， apigenin， kaempferol， isorhamnetin， rhododendron， isoquercetin， kaempferol-3-furan arabinoside， 2，6-octadecanediacetylic acid. CONCLUSIONS A total of 16 chemical components with estrogenic effect are screened from total flavonoids of Cuscutae Semen in the study， which can provide reference for the development of phytoestrogens.

Research advances in role of angiogenesis in diabetic ulcer and traditional Chinese medicine intervention / 中国中药杂志

Diabetic ulcer(DU) is one of the common complications of diabetes often occurring in the peripheral blood vessels of lower limbs or feet with a certain degree of damage. It has high morbidity and mortality, a long treatment cycle, and high cost. DU is often clinically manifested as skin ulcers or infections in the lower limbs or feet. In severe cases, it can ulcerate to the surface of tendons, bones or joint capsules, and even bone marrow. Without timely and correct treatment, most of the patients will have ulceration and blackening of the extremities. These patients will not be able to preserve the affected limbs through conservative treatment, and amputation must be performed. The etiology and pathogenesis of DU patients with the above condition are complex, which involves blood circulation interruption of DU wound, poor nutrition supply, and failure in discharge of metabolic waste. Relevant studies have also confirmed that promoting DU wound angiogenesis and restoring blood supply can effectively delay the occurrence and development of wound ulcers and provide nutritional support for wound healing, which is of great significance in the treatment of DU. There are many factors related to angiogenesis, including pro-angiogenic factors and anti-angiogenic factors. The dynamic balance between them plays a key role in angiogenesis. Meanwhile, previous studies have also confirmed that traditional Chinese medicine can enhance pro-angiogenic factors and down-regulate anti-angiogenic factors to promote angiogenesis. In addition, many experts and scholars have proposed that traditional Chinese medicine regulation of DU wound angiogenesis in the treatment of DU has broad prospects. Therefore, by consulting a large number of studies available, this paper expounded on the role of angiogenesis in DU wound and summarized the research advance in traditional Chinese medicine intervention in promoting the expression of angiogenic factors [vascular endothelial growth factor(VEGF), fibroblast growth factor(FGF), and angiopoietin(Ang)] which played a major role in promoting wound angiogenesis in the treatment of DU to provide ideas for further research and new methods for clinical treatment of DU.

Research progress in role of autophagy in diabetic wound healing and traditional Chinese medicine intervention / 中国中药杂志

Diabetic ulcer(DU) is a chronic and refractory ulcer which often occurs in the foot or lower limbs. It is a diabetic complication with high morbidity and mortality. The pathogenesis of DU is complex, and the therapies(such as debridement, flap transplantation, and application of antibiotics) are also complex and have long cycles. DU patients suffer from great economic and psychological pressure while enduring pain. Therefore, it is particularly important to promote rapid wound healing, reduce disability and mortality, protect limb function, and improve the quality of life of DU patients. By reviewing the relevant literatures, we have found that autophagy can remove DU wound pathogens, reduce wound inflammation, and accelerate ulcer wound healing and tissue repair. The main autophagy-related factors microtubule-binding light chain protein 3(LC3), autophagy-specific gene Beclin-1, and ubiquitin-binding protein p62 mediate autophagy. The traditional Chinese medicine(TCM) treatment of DU mitigates clinical symptoms, accelerates ulcer wound healing, reduces ulcer recurrence, and delays further deterioration of DU. Furthermore, under the guidance of syndrome differentiation and treatment and the overall concept, TCM treatment harmonizes yin and yang, ameliorates TCM syndrome, and treats underlying diseases, thereby curing DU from the root. Therefore, this article reviews the role of autophagy and major related factors LC3, Beclin-1, and p62 in the healing of DU wounds and the intervention of TCM, aiming to provide reference for the clinical treatment of DU wounds and subsequent in-depth studies.

Cost-Effectiveness Analysis of Combined Chemotherapy Regimen Containing Bedaquiline in the Treatment of Multidrug-Resistant Tuberculosis in China / 生物医学与环境科学（英文）

OBJECTIVE@#This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China.@*METHODS@#A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs. CR was determined.@*RESULTS@#BR ( vs. CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan).@*CONCLUSION@#BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR.

Herbal-moxa plaster for diarrhea type irritable bowel syndrome of spleen and kidney yang deficiency: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.

Diagnostic value of novel hepatic fibrosis markers in assessing cirrhosis in patients with chronic hepatitis C / 中华肝脏病杂志

Objective: To investigate the efficacy of chitinase-3-like protein 1 (CHI3L1) and Golgi protein 73 (GP73) in the diagnosis of cirrhosis and the dynamic changes of CHI3L1 and GP73 after HCV clearance in patients with chronic hepatitis C (CHC) treated with direct-acting antiviral drugs (DAAs). The comparison of continuous variables of normal distribution were statistically analyzed by ANOVA and t-test. The comparison of continuous variables of non-normal distribution were statistically analyzed by rank sum test. The categorical variables were statistically analyzed by Fisher's exact test and χ(2) test. Correlation analysis was performed using Spearman correlation analysis. Methods: Data of 105 patients with CHC diagnosed from January 2017 to December 2019 were collected. The receiver operating characteristic curve (ROC curve) was plotted to study the efficacy of serum CHI3L1 and GP73 for the diagnosis of cirrhosis. Friedman test was used to compare CHI3L1 and GP73 change characteristics. Results: The areas under the ROC curve for CHI3L1 and GP73 in the diagnosis of cirrhosis at baseline were 0.939 and 0.839, respectively. Serum levels of CHI3L1 and GP73 in the DAAs group decreased significantly at the end of treatment compared with baseline [123.79 (60.25, 178.80) ng/ml vs. 118.20 (47.68, 151.36) ng/ml, P = 0.001; 105.73 (85.05, 130.69) ng/ml vs. 95.52 (69.52, 118.97) ng/ml, P = 0.001]. Serum CHI3L1 and GP73 in the pegylated interferon combined with ribavirin (PR) group were significantly lower at the end of 24 weeks of treatment than the baseline [89.15 (39.15, 149.74) ng/ml vs. 69.98 (20.52, 71.96) ng/ml, P < 0.05; 85.07 (60.07, 121) ng/ml vs. 54.17 (29.17, 78.65) ng/ml, P < 0.05]. Conclusion: CHI3L1 and GP73 are sensitive serological markers that can be used to monitor the fibrosis prognosis in CHC patients during treatment and after obtaining a sustained virological response. Serum CHI3L1 and GP73 levels in the DAAs group decreased earlier than those in the PR group, and the serum CHI3L1 levels in the untreated group increased compared with the baseline at about two years of follow-up.

Ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China: a CR-HepB-based real-world study / 中华肝脏病杂志

Objective: To understand ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China. Methods: Patients with chronic HBV infection:demographic, virologic, hematologic, blood biochemistry, and antiviral treatment data were extracted from the China Registry of Hepatitis B (CR-HepB) database between 2012 and 2022 for descriptive statistics and change trend analysis. Multiple group comparisons were conducted using the Kruskal Wallis H test, while counting data was compared between groups using χ (2) test. Results: A total of 180 012 patients with chronic HBV infection were included, with a median age of 40 years old, and a male proportion accounting for 60.2%. The HBeAg positive rate was 43.3%. Over time, the median age of new patients each year increased from 39 to 47 years, while the HBeAg positive rate decreased from 51.3% to 32.8%. The initial diagnosis of patients was mainly CHB (71.4%), followed by hepatitis B cirrhosis (11.8%), inactive HBsAg carrier status (10.6%), and chronic HBV carrier status (6.2%). Among the newly registered patients every year from 2012 to 2022, the proportion of hepatitis B cirrhosis remained stable, but after 2019, the proportion of CHB increased and the proportion of other diagnoses decreased. The proportion of patients with cirrhosis increased with age in different age groups, with 3.5%, 19.3%, and 30.4% in the < 40, 40-69, and≥70 age groups, respectively. The proportion of women in patients with cirrhosis also increased with age, from 16.1% in those < 30 years old to 44.3% in those≥80 years old. From 2012 to 2022, the proportion of patients receiving first-line nucleos(t)ide analog antiviral treatment increased year by year, from 51.0% in 2012-2013 to 99.8% in 2022. Conclusion: The CR-HepB registration data reflect the changes in clinical characteristics and antiviral treatment patterns in patients with chronic HBV infection in China over the past ten years and can thus provide a reference to promote hepatitis B diagnosis and treatment practice, as well as scientific research.
