Gastroesophageal reflux related cough is located in the lung and stomach.The basic pathogenesis is the inversion of stomach qi and the lung loss propagating and descending.In view of the above,based on the theory of"relevance of lung and stomach",this article analyzed the modern mechanism of"relevance of lung and stomach"in gastroesophageal reflux related cough,which included"microinhalation"theory,"esophagus-bronchial reflex"theory,and"airway neurogenic inflammation"theory.This article also put forward the TCM disease name of"gastric cough",and the treatment methods of"simultaneous treatment of lung and stomach"and"treatment of cough from stomach",which would provide new ideas for the theoretical and mechanism research of TCM treatment of gastroesophageal reflux related cough.

Objective:To evaluate the effects of pegylated interferon (Peg-IFN) alfa-2b combined with nucleotide analogues (NAs) on the recurrence of hepatitis B-related liver cancer after resection, and to explore the changes of HBsAg and HBV DNA in patients with chronic hepatitis B liver cancer during postoperative treatment.Methods:The prospective study was conducted. Clinical data of 43 patients with hepatitis B-related liver cancer who underwent radical resection treated in 900th Hospital of People′s Liberation Army were prospectively analyzed from January 2020 to December 2021. Among 43 patients, there were 39 males and 4 females, the age was 30-76 years. According to different treatment methods they were divided into two groups, the patients treated by Peg-IFN alfa-2b combined with NAs were devided into the IFN group( n=10), and those treated by NAs alone into the NAs group( n=33). Two-pair semi-quantitative were collected every 3 months after operation. The recurrence-free survival rate, recurrence time after 2 years in the two groups, the clearance rate and the negative rate of HBsAg and HBV DNA in the two groups. Peg-IFN alfa-2b was evaluated in improving the prognosis of hepatitis B-related liver cancer. The measurement data of normal distribution were expressed by mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Chi-square test was used for comparison between the two groups of count data. Repeated analysis of measurement variance was used for analysis HBsAg and HBV DNA changes of the interferon group overall survival time and recurrence-free surrival time of patients was estimated using Kaplan-Meier method and the difference between groups was assessed using Log-rank test. Results:HBsAg and HBV DNA: The HBsAg clearance rate at 24 weeks and that at 48 weeks in the IFN group were 24.6% and 59.0% respectively. The HBsAg negative rate at 48 weeks was 16.7%. The HBV DNA clearance rate at 24 weeks and that at 48 weeks were 33.9% and 53.8% respectively. The HBV DNA negative rate was 0 at 48 weeks. The levels of HBsAg and HBV DNA in the IFN group decreased gradually with time. There were statistically differences between the levels of HBsAg and HBV DNA at 0 weeks, 24 weeks and 48 weeks( P<0.05). The 2-year overall survival rates of IFN group and NAs group were 100% and 90.9% respectively. The 2-year recurrence-free survival rates were 90.0% and 63.6% respectively. There were no significant statistical differences in the overall survival rate and recurrence-free survival rate between the groups ( P>0.05). The postoperative recurrence time of the IFN group and the NAs group were (15.00±7.07) months and (5.78±3.39) months respectively. The difference between the two groups was statistically significant ( t=3.160, P<0.01). Conclusion:Long-term antiviral therapy of Peg-IFN alfa-2b combined with NAs can prolong the recurrence time of liver cancer, reduce the levels of HBsAg and HBV DNA in serum, and potentially improve the survival rate of the patients compared with therapy of NAs alone.

Enterotoxigenic Escherichia coli（ETEC）infection can induce watery diarrhea，leading to dehydration，electrolyte disturbance，and even death in severe cases. Recombinant B subunit/inactivated whole-cell cholera（rBS/WC）vaccine is effective in preventing ETEC infectious diarrhea. On the basis of the latest evidence on etiology and epidemiology of ETEC，as well as the effectiveness，safety，and health economics of rBS/WC vaccine，National Clinical Research Center for Child Health（The Children’s Hospital，Zhejiang University School of Medicine）and Zhejiang Provincial Center for Disease Control and Prevention invited experts to develop expert consensus on rBS/WC vaccine in prevention of ETEC infectious diarrhea. It aims to provide the clinicians and vaccination professionals with guidelines on using rBS/WC vaccine to reduce the incidence of ETEC infectious diarrhea.

Pituitary neuroendocrine tumors (PitNETs) are benign tumors arising from the adenohypophysis and can destroy the surrounding dura mater and invade adjacent structures. Dural invasion, as an important biological manifestation of PitNETs invasiveness and an important basis for PitNETs pathological classification, has become an important part in invasive study of PitNETs. In this paper, the research progress of dural invasion of PitNETs carried out at home and abroad in recent years has been reviewed from aspects of anatomical structure, imaging manifestations and histopathology, and the latest results of dural invasion in PitNETs invasion are summarized.

Hilar cholangiocarcinoma(HCCA) is a hotpot and a difficult point in the field of hepatobiliary surgery. HCCA is the most common type of cholangiocarcinoma and is characterized by atypical early clinical manifestations, rapid progression and poor prognosis. There is no specific marker for HCCA and its preoperative diagnosis and evaluation mainly relies on imaging examination. Surgical treatment is still the main treatment, but most patients have lost the opportunity of surgical resection by the time of treatment. In recent years, a large number of studies have been conducted on the diagnosis and treatment of HCCA at home and abroad, and the efficacy of HCCA has been improved. Perioperative management, including the selection of preoperative drainage and perioperative chemoradiotherapy and others, improved postoperative survival. Among them, the application of preoperative radiotherapy and chemotherapy in the field of liver transplantation has achieved quite good results. Targeted therapy and immunotherapy have provided new treatment methods for HCCA. This paper reviews the diagnosis and multimodal treatment of HCCA.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.

Objective     To verify the feasibility and accuracy of the "lung surface intersegmental constant proportion landmarks", developed by our center, in identifying intersegmental planes during pulmonary segmentectomy. Methods    We prospectively enrolled the patients who planned to receive thoracoscopic segmentectomy in West China Hospital of Sichuan University and The Third People's Hospital of Chengdu from September 2021 to October 2021. We took a relatively objective and feasible method, intravenous injection of indocyanine green, in identifying intersegmental planes as standard control. We intraoperatively judged the consistency between "lung surface intersegmental constant proportion landmarks" and intravenous injection of indocyanine green in identifying intersegmental planes. We discerned main landmarks of intersegmental plane by the constant proportion segment module, which was built based on the "lung surface intersegmental constant proportion landmarks", as well as distinguished the planes with discrepant fluorescence by peripheral intravenous indocyanine green injection. When the distance between the landmarks determined by the "ung surface intersegmental constant proportion landmarks" and the segmental boundaries displayed by indocyanine green  fluorescence staining was ≤1 cm, the landmarks were judged to be consistent with the planes with discrepant fluorescence. As long as one of the landmarks was judged to be consistent, the method was considered to be feasible and accurate. Results 聽 聽 A total of 21 patients who underwent thoracoscopic segmentectomy were enrolled, with 5 male and 16 female patients. The median age was 55 years, ranging from 34 to 76 years. A total of 11 patients received left-side surgery, while 10 patients received right-side surgery. In the operations of 21 pulmonary segmentectomies, at least one intersegmental landmark determined by the "lung surface intersegmental constant proportion landmarks" was consistent with the intersegmental plane determined by indocyanine green fluorescence staining in each patient. Conclusion 聽 聽The intersegmental landmarks determined by the "lung surface intersegmental constant proportion landmarks" are consistent with that determined by indocyanine green fluorescence staining. The method of "lung surface intersegmental constant proportion landmarks" is feasible and accurate in identifying intersegmental planes during pulmonary segmentectomy.

Objective: To compare the difference of diagnostic ability between ultrasound radiomics (USR) and different conventional imaging models of central neck (Ⅵ) lymph node metastasis in papillary thyroid carcinoma (PTC). Methods: A training set of 609 cases was set up. USR features were extracted and screened by USR method. A weighted formula was established to calculate the USR score of each patient by ultrasound image. The USR score of the best diagnostic ability was obtained by statistical method and set as the diagnostic criterion. A test set of 326 cases was established to compare the diagnostic ability of USR score with ultrasound (US), computed tomography (CT) and US combined CT. Results: The accuracy, sensitivity, specificity, area under ROC curve and Youden index of USR score in test set were 0.804, 0.867, 0.770, 0.766, 0.533, respectively, which were significantly higher than the corresponding values of US, CT and US combined CT(all P=0.000). Conclusions USR score obtained with USR method can effectively predict lymph node metastasis in Ⅵ region of PTC. The diagnostic efficiency and clinical value of USR score were significantly higher than those of conventional medical imaging models.
