Objective:To investigate the clinical effect of jujube core-shaped tissue resection technique in the treatment of alar reduction.Methods:A retrospective analysis was performed for the clinical data of patients who underwent alar reduction from February 2019 to June 2022. A spindle-shaped incision line was designed along the outer edge of the base of the nasal lobule, with a width of 4-5 mm and a length of 8-12 mm. The incision line was 1-2 mm away from the alar groove, and the inner side of the design line was extended to the inside of the nasal vestibule. After the incision was made, the subcutaneous tissue was undermining dissected with curved sharp scissors, and the shape of the extended excision tissue was similar to that of jujube core. After reduction, the incision was closed with vertical mattress suture. The surgical effect and complications were followed up after surgery, and an independent attending plastic surgeon evaluated the outcome and scarring based on photos before and at the last postoperative follow-up using the global aesthetic improvement scale (GAIS) and the Vancouver scar scale (VSS). GAIS is graded as 1, 2, 3, 4, and 5 points, and the lower the score, the better the improvement(≤3 points as effective improvement). VSS includes four parameters: color (0-3 points), thickness (0-4 points), vascular distribution (0-3 points), and softness (0-5 points). The higher the score, the more significant the scar is.Results:A total of 20 patients were enrolled, including 6 males and 14 females, aged 20 to 33 years, with an average age of 24.9 years. Before the operation, there were different degrees of alar flare and alar hypertrophy. After surgery, 13 patients had mild swelling, ecchymosis, which resolved after 3 days. There were no major complications as infection, incision dehiscence, and delayed healing. After 3 to 16 months of postoperative follow-up, 2 patients gradually developed cartilage deformation and affected the appearance of the nostrils 6 to 9 months after surgery due to the combination of rib-based rhinoplasty, and the satisfactory results were obtained after revision surgery. The symmetry of the nostrils was significantly improved. The GAIS score of 20 patients was (1.20±0.41) points, of which, 16 patients were rated as 1 point and 4 patients were rated as 2 points, all of which met the improvement criteria, and the VSS score was (1.45±0.60) points, in which the average score for color, thickness, vasculature and compliance are 0.60, 0.05, 0.55 and 0.30 points respectively.Conclusion:The application of jujube core-shaped tissue resection technique for alar reduction can increase the amount of tissue removal with the same incision width, which can not only fully narrow the alar effectively but also correct the hypertrophy of the alar tissue.

OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.

Objective:This study aims to compare the antiviral treatment similarities and differences in the population covered by the 2024 version of the World Health Organization's (WHO) hepatitis B prevention and treatment guidelines and the current Chinese hepatitis B prevention and treatment guidelines, so as to explore their impact on the indications for antiviral therapy in Chinese patients with chronic hepatitis B (CHB).Methods:The information of patients with chronic hepatitis B virus infection who did not receive antiviral treatment was collected through the registration database of the China Clinical Research Platform for Hepatitis B Elimination. Descriptive statistics were conducted on the demographic, blood, biochemical, and virological levels of patients according to the treatment recommendations of the two versions of the guidelines. The Mann-Whitney U test and χ2 test were used to compare the differences and proportional distribution of the treatment populations covered by the two guidelines. The χ2 test was used to analyze the coverage rate of different antiviral treatment indications.Results:A total of 21,134 CHB patients without antiviral treatment were enrolled. 69.4% of patients met the 2024 versions of the WHO guidelines' recommendations. 85.0% of patients met the current Chinese hepatitis B prevention and treatment guidelines. The WHO guidelines for antiviral therapy indications were met in younger patients with higher levels of ALT, AST, and APRI scores, as well as greater proportion of patients with higher viral loads (P<0.001). The WHO guidelines recommended a cut-off value of APRI>0.5, which raised the proportion of patients on antiviral therapy from 6.6% to 30.9%. 45.7% of patients met the antiviral indications for HBV DNA >2000 IU/ml with abnormal transaminase (ALT>30 U/L for males and ALT>19 U/L for females). The reduced APRI diagnostic cut-off value and ALT treatment threshold had further increased the treatment coverage rate by 91.6% in patients with chronic HBV infection in line with the 2024 versions of WHO guidelines.Conclusion:The reduction of the APRI diagnostic cut-off value and the ALT treatment threshold, based on the current hepatitis B guidelines of China, will further improve the treatment coverage of CHB patients.

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.

Metastasis is the main cause of cancer-related death. Growing evidence has shown that changes in glucose metabolism in nasopharyngeal carcinoma cells affect the invasion and metastasis of nasopharyngeal carcinoma through many pathways. This review summarizes the molecular mechanism underlying abnormal glucose metabolism in nasopharyngeal carcinoma cells and analyzes its relationship with the invasion and metastasis of nasopharyngeal carcinoma, including aerobic glycolysis, aerobic oxidation, and pentose phosphate pathway. The aim is to provide novel approaches using the relationships among glucose metabolism, invasion, and metastasis in the targeted therapy of nasopharyngeal carcinoma.

ObjectiveTo study the effect of flower removal on the content of three alkaloids in different parts of Fritillaria thunbergii from different regions and at different growth stages. MethodThe content of peiminine， peimine， and peimisine in the bulb， root， stem， and leaf of F. thunbergii after flower removal and with flower un-removed at different growth stages and in different regions were determined simultaneously by ultra-performance liquid chromatography-evaporative light scattering detection （UPLC-ELSD） method. The UPLC was conducted on ACQUITY UPLC BEH C₁₈ column （2.1 mm × 150 mm， 1.7 μm） with the mobile phase of 0.02% triethylamine aqueous solution （A） and methanol （B）elution gradient（0-2 min， 45%A； 2-5 min， 45%-25%A； 5-7 min， 25%A； 7-17 min， 25%-10%A； 17-20 min， 10%A）， flow velocity of 0.20 mL·min^-1， column temperature 35 °C， sample room temperature of 20 °C， and injection volume of 3 µL. The ELSD was carried out at drift tube temperature 45 °C and with the sprayer parameter of 40%. ResultThe flower removal significantly increased the yield of F. thunbergii. At the budding stage， the alkaloid content in the bulb of F. thunbergii from Ningbo in Zhejiang， Pan'an in Zhejiang， and Nantong in Jiangsu after flower removal were significantly higher than that of flowering un-removal treatment， while it showed no significant difference between the flower removal and un-removal treatments for the samples from Fengjie in Chongqing. At the flowering stage， the alkaloid content in the bulb of F. thunbergii from Nantong in Jiangsu after flower removal was significantly higher than that of flower un-removal treatment， while it showed an opposite trend for the samples from Pan'an in Zhejiang and Fengjie in Chongqing and had no significant difference between the two treatments for the samples from Ningbo in Zhejiang. At the bulb expansion stage， the alkaloid content in the bulb of F. thunbergii from Ningbo in Zhejiang and Pan’an in Zhejiang after flower removal were significantly higher than that of flower un-removal treatment， which was opposite for the samples from Nantong in Jiangsu and had no significant difference between the treatments for the samples from Fengjie in Chongqing. At the harvest stage， except for the samples from Pan'an in Zhejiang， the samples from the rest 3 regions showed decreased alkaloid content in the bulb after flower removal compared with that of flower un-removal treatment. The alkaloid content in the leaf was higher than that in the bulb of F. thunbergii at all growth stages and from different origins. ConclusionFlower removal can increase the yield of F. thunbergii. The alkaloid content in the bulb of F. thunbergii with flower removed was higher than that with flower un-removed at the budding stage， while this trend was reversed at the harvest stage. Both the yield and the alkaloid content of F. thunbergii from Pan'an in Zhejiang were increased by flower removal. The above-ground part of F. thunbergii has a potential development value.

Objective To investigate the impact of the change in anti-hepatitis B virus (HBV) therapy indication on treatment rate and the features of the population requiring treatment. Methods The treatment-naïve patients with chronic hepatitis B (CHB) in the China Registry of Hepatitis B (CR-HepB) database were selected as subjects, and related demographic, virological, hematological, and biochemical data were collected. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results A total of 3640 treatment-naïve CHB patients were included in this study, among whom 64.4% were male, 68.7% had an age of 30-59 years, and 46.8% had an indeterminate clinical stage. According to the 2015 and 2019 editions of Guidelines for the prevention and treatment of chronic hepatitis B and the 2022 edition of expert consensus, the number of patients who had the indication for antiviral therapy was 625(17.2%), 1333(36.6%), and 2890(79.4%), respectively. The number of patients requiring treatment was increased by 1557 according to the 2022 edition of expert consensus, among whom 1424(91.5%) met the treatment threshold of alanine aminotransferase (ALT) > 30 U/L for male patients or ALT > 19 U/L for female patients. The additional patients requiring treatment according to the 2022 edition of expert consensus had significantly higher levels of ALT and HBV DNA and significantly lower scores of APRI and FIB-4 than the additional patients requiring treatment according to the 2019 edition of Guidelines (all P < 0.05). Conclusion The expansion of antiviral therapy indications for CHB may significantly increase the proportion of CHB patients receiving antiviral treatment and help mild CHB patients at the risk of disease progression to receive timely treatment and achieve the improvement in long-term prognosis.
