Small cell lung cancer （SCLC） is characterized by rapid onset， high invasiveness， and a strong tendency for recurrence and metastasis， which aligns with the pathogenic characteristics of wind pathogen in traditional Chinese medicine （TCM）. This paper explores the pathological mechanism and dynamic pattern identification and treatment of SCLC from the perspective of "internal wind in hidden circulation". It is proposed that the core pathogenesis of SCLC is rooted in depletion of healthy qi， with binding of phlegm， stasis， and toxin. When pathogenic factors become excessive， the ascending and descending of yang qi becomes disordered， transforming into wind. This leads to internal wind in hidden circulation， which moves erratically and damages healthy qi. In the limited stage， cancer toxin accumulates and internal wind arises covertly， treatment for which should focus on regulating qi and resolving toxin， defending against wind and resisting pathogen with modified Bufei Decoction （补肺汤） and Shengjiang Powder （升降散）. In the early extensive stage， phlegm and stasis generate wind， and internal wind spreads through collate-rals； treatment should resolve phlegm and dispel stasis， extinguish wind and resolve toxin， with modified Lingjiao Gouteng Decoction （羚角钩藤汤） combined with Tianma Gouteng Beverage （天麻钩藤饮）. During the treatment stage， there is qi and yin depletion， and deficient wind harassing the interior， for which it is recommended to boost qi and nourish yin， soften the liver and extinguish wind， with modified Zhengan Xifeng Decoction （镇肝熄风汤） combined with Qingzao Jiufei Decoction （清燥救肺汤）. In the progression stage， internal wind stirs again and cancer toxin scurries； treatment should focus on strengthening the healthy qi and replenishing essence， restraining wind and penetrating toxin， with modified Sanjia Fumai Decoction （三甲复脉汤）. In the terminal stage， yin and yang are on the verge of dissociation and depleted yang floats upward； treatment should constrain and astringe to prevent collapse， rescue yang and contain yin， with modified Dihuang Drink （地黄饮子） combined with Laifu Decoction （来复汤）.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To explore the efficacy of precise and empirical bismuth-containing quadruple therapy guided by clarithromycin sensitivity testing in the first eradication of Helicobacter pylori ( H. pylori) in Ningxia. Methods:From August 12, 2022 to March 22, 2023, 600 patients diagnosed as H. pylori-positive by 14C-urea breath test ( 14C-UBT) for the first time in People′s Hospital of Ningxia Hui Autonomous Region, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region, Zhongwei People′s Hospital, Yanchi County People′s Hospital, and Pingluo People′s Hospital were selected, and divided into empirical treatment group (hereinafter referred to as the empirical group), genetic testing group (hereinafter referred to as the genetic group), and drug sensitivity testing group (hereinafter referred to as the drug sensitivity group) by using random number table with 200 patients in each group. The empirical group did not undergo drug sensitivity testing and genetic testing, while the genetic and drug sensitivity groups were confirmed to be sensitive to clarithromycin through genetic testing and drug sensitivity testing, and the patients with drug-resistant were excluded, respectively. All the patients of the 3 groups received the same clarithromycin bismuth-containing quadruple therapy. Intention-to-treat (ITT) and per-protocol (PP) analyses were performed to compare the eradication rates of H. pylori among 3 groups. Cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER) were used for cost-effectiveness and sensitivity analysis based on the ITT. Chi-square test was used for statistical analysis. Results:There were 200, 126, and 168 patients included in the empirical group, genetic group, and drug sensitivity group in ITT analysis, and 190, 123, and 164 patients were enrolled in the 3 groups in PP analysis, respectively. The results of ITT analysis showed that the eradication rates of H. pylori in the empirical group, genetic group, and drug sensitivity group were 80.5% (161/200), 94.4% (119/126), and 95.2% (160/168), respectively. The results of PP analysis indicated that the eradication rates of H. pylori in the 3 groups were 84.7% (161/190), 96.7% (119/123), and 97.6% (160/164), respectively, and the differences were statistically significant ( χ2=25.39 and 24.93, both P<0.001). The H. pylori eradication rates of genetic group and drug sensitivity group were both higher than that of empirical group in ITT and PP analysis( χ2=12.40, 17.80, 11.42, and 17.13; all P<0.001). The cost-effectiveness analysis showed that the direct treatment cost of the empirical group, genetic group, and drug sensitivity group was 400.8, 729.2, and 779.2 yuan, respectively, and the CER was 4.98, 7.72, and 8.18 yuan/%, respectively. Compared to the empirical group, the ICER of the genetic group and drug sensitivity group was 23.6 and 25.7 yuan/%, respectively. The sensitivity analysis demonstrated that, when the cost of genetic testing reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 21.8 or 25.5 yuan/%, respectively. When the cost of drug sensitivity testing reduced or increased by 20%, the ICER of the drug sensitivity group compared to the empirical group was 23.3 or 28.2 yuan/%. When the cost of gastroscopy reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 20.8 or 26.5 yuan/%, and the ICER of the drug sensitivity group compared to the empirical group was 23.0 or 28.4 yuan/%, respectively. Conclusion:In Ningxia, if the clarithromycin bismuth-containing quadruple regimen is applied as the first H. pylori eradication regimen, in order to achieve the clinical eradication efficacy of H. pylori, and the patients can accept an additional payment of 23.6 or 25.7 yuan for each 1% increasing in the H. pylori eradication rate, then the precision treatment after clarithromycin resistance test is recommended.

Central precocious puberty (CPP) is a common pediatric endocrine disease caused by premature activation of the hypothalamic-pituitary-gonadal axis, featured by rapid development of internal and external reproductive organs and secondary sexual characteristics in girls before age 8 and boys before age 9.The gonadotropin-releasing hormone analogue (GnRHa) is the first choice for the treatment of CPP.Currently, 3.75 mg/ month sustained -release short-acting dosage form (1M depot formulations) is the most commonly used in China.The development of long-acting dosage form will reduce injection times and clinic visits.At present, the 3-month long-acting dosage form (11.25 mg 3M depot formulations) of Leprorelin microsphere has been approved in China.However, clinical practice experience of 3-month Leuprorelin acetate depot formulations is lacking in China.Therefore, in this paper, existing clinical evidence for this dosage form was reviewed to provide evidence-based medicine support for its clinical application.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Among the fire victims, respiratory tract injury resulted from smoke inhalation is the major cause of death. Particulate substances in smoke, toxic and harmful gas, and chemical substances act together would rapidly induce the occurrence of dramatic pathophysiologic reaction in the respiratory tract, resulting in acute injury to the respiratory tract, thus inducing serious injury to it and acute respiratory distress syndrome, leading to death of the victims. In recent years, the pathophysiologic mechanism of severe smoke inhalation injury has been gradually clarified, thus appreciable advances in its treatment have been achieved. This paper is a brief review of above-mentioned aspects.
