Recently， Asian Pacific Association for the Study of the Liver published the recommendations for the diagnosis and management of non-cirrhotic portal fibrosis （NCPF）/idiopathic portal hypertension （IPH）. The guidelines mainly elaborate on the definition， diagnosis， histological features， natural history， and management of NCPF/IPH， in order to strengthen the understanding of NCPF/IPH-related issues and establish a global consensus. This article makes an excerpt of the key statements in the guidelines.

OBJECTIVE: To explore the rules of acupoint selection and compatibility of acupuncture and moxibustion in treatment of chronic cough using data mining. METHODS: The ancient and modern medical record cloud platform, and the databases, i.e. CNKI, Wanfang, VIP, EMbase, Web of Science and PubMed, were searched to screen the ancient and modern literature on acupuncture and moxibustion treatment of chronic cough. The prescription database was established for acupuncture and moxibustion treatment of chronic cough, and the analysis conducted on the frequency and use percentage in the aspects of intervention measures, acupoint selection, acupoint distribution, meridian tropism, special points and acupoint combination, as well as the association rules and clustering rules of acupoint selection. The subgroup analysis was performed in accordance with the etiology of chronic cough and intervention measures. RESULTS: A total of 106 articles were included and 158 prescriptions were extracted. The intervention measures were acupuncture, moxibustion, herbal medication and the combination of several measures. The high-frequency acupoints included Feishu (BL13), Zusanli (ST36), Dazhui (GV14), Pishu (BL20), Danzhong (CV17), Shenshu (BL23), Lieque (LU7), Dingchuan (EX-B1), Tiantu (CV22), and Fenglong (ST40). These acupoints are mainly distributed on the back, lumbar region, chest and abdomen. The involved meridians were bladder meridian of foot-taiyang, conception vessel, and lung meridian of hand-taiyin. The special points covered back-shu points, crossing points and five-shu point. Regarding the compatibility of acupoints, the combination of upper and lower points, and the combination of front and back points were predominant in treatment. The analysis of association rules found that the support of Feishu (BL13)→Zusanli (ST36) was the highest; the cluster analysis obtained 8 clusters of acupoints. The acupoint compatibility and overall rules were similar when cough variant asthma (CVA) or the mixed reasons were involved, and the local treatment approach was adopted if the etiology of disease was related to upper airway cough syndrome (UACS) and gastroesophageal reflux cough (GERC). The acupoint selection was similar among different intervention measures. When two kinds of measures were combined in treatment, Feishu (BL13), Pishu (BL20) and Zusanli (ST36) were the most common. CONCLUSION In treatment with acupuncture and moxibustion for chronic cough, the acupoints are selected on the affected local area, depending on syndrome differentiation, and focusing on back-shu points. The main acupoints are Feishu (BL13), Zusanli (ST36), Dazhui (GV14), Pishu (BL20), Danzhong (CV17) and Shenshu (BL23). The combined therapy is dominant with acupuncture, moxibustion and herbal medicine involved.

Digital intraoral scanning is a hot topic in the field of oral digital technology.In recent years,digital intra-oral scanning has gradually become the mainstream technology in orthodontics,prosthodontics,and implant dentistry.The precision of digital intraoral scanning and the accuracy and stitching of data collection are the keys to the success of the impression.However,the operators are less familiar with the intraoral scanning characteristics,imaging process-ing,operator scanning method,oral tissue specificity of the scanned object,and restoration design.Thus far,no unified standard and consensus on digital intraoral scanning technology has been achieved at home or abroad.To deal with the problems encountered in oral scanning and improve the quality of digital scanning,we collected common expert opin-ions and sought to expound the causes of scanning errors and countermeasures by summarizing the existing evidence.We also describe the scanning strategies under different oral impression requirements.The expert consensus is that due to various factors affecting the accuracy of digital intraoral scanning and the reproducibility of scanned images,adopting the correct scanning trajectory can shorten clinical operation time and improve scanning accuracy.The scanning trajec-tories mainly include the E-shaped,segmented,and S-shaped methods.When performing fixed denture restoration,it is recommended to first scan the abutment and adjacent teeth.When performing fixed denture restoration,it is recommend-ed to scan the abutment and adjacent teeth first.Then the cavity in the abutment area is excavated.Lastly,the cavity gap was scanned after completing the abutment preparation.This method not only meets clinical needs but also achieves the most reliable accuracy.When performing full denture restoration in edentulous jaws,setting markers on the mucosal tissue at the bottom of the alveolar ridge,simultaneously capturing images of the vestibular area,using different types of scanning paths such as Z-shaped,S-shaped,buccal-palatal and palatal-buccal pathways,segmented scanning of dental arches,and other strategies can reduce scanning errors and improve image stitching and overlap.For implant restora-tion,when a single crown restoration is supported by implants and a small span upper structure restoration,it is recom-mended to first pre-scan the required dental arch.Then the cavity in the abutment area is excavated.Lastly,scanning the cavity gap after installing the implant scanning rod.When repairing a bone level implant crown,an improved indi-rect scanning method can be used.The scanning process includes three steps:First,the temporary restoration,adjacent teeth,and gingival tissue in the mouth are scanned;second,the entire dental arch is scanned after installing a standard scanning rod on the implant;and third,the temporary restoration outside the mouth is scanned to obtain the three-di-mensional shape of the gingival contour of the implant neck,thereby increasing the stability of soft tissue scanning around the implant and improving scanning restoration.For dental implant fixed bridge repair with missing teeth,the mobility of the mucosa increases the difficulty of scanning,making it difficult for scanners to distinguish scanning rods of the same shape and size,which can easily cause image stacking errors.Higher accuracy of digital implant impres-sions can be achieved by changing the geometric shape of the scanning rods to change the optical curvature radius.The consensus confirms that as the range of scanned dental arches and the number of data concatenations increases,the scanning accuracy decreases accordingly,especially when performing full mouth implant restoration impressions.The difficulty of image stitching processing can easily be increased by the presence of unstable and uneven mucosal mor-phology inside the mouth and the lack of relatively obvious and fixed reference objects,which results in insufficient ac-curacy.When designing restorations of this type,it is advisable to carefully choose digital intraoral scanning methods to obtain model data.It is not recommended to use digital impressions when there are more than five missing teeth.

ObjectiveTo investigate the factors related to the abandonment of upper limb prostheses. MethodsA total of 138 amputees fitting with upper limb prostheses at Guangdong Work Injury Rehabilitation Hospital from January 1st, 2016 to December 31st, 2022 were reviewed through case data, and those whose Functional Independence Measure scores improved after fitting were selected. A total of 126 amputees were investigated through telephone or WeChat with a questionnaire. The questionnaire was designed based on Trinity Amputation and Prosthesis Experience Scale-Revised, short form of Health Survey (SF-36) and World Health Organization Quality of Life Scale-Brief, and the items that may lead to the abandonment of upper limb prostheses were summarized in four factors: amputee, prosthetic fitting, prosthetic training, and environment and social policy. ResultsThe overall abandonment rate was 23.0% (29/126). There was significant difference between the the amputee abandonment or using prostheses in educational levels, amputation levels and residual limb condition (χ² > 6.808, P < 0.05); types of prostheses, whether functional prostheses, expectation for prosthesis, comfort of the prostheses, convenience of putting on and taking off, sensitivity of manipulation, weight of the prostheses, satisfaction with the appearance, skill levels of the prosthetist, the satisfaction after prosthesis installation and satisfaction with the prostheses in use (χ² > 13.083, P < 0.05); training levels before prosthesis assembly, the mastery of functional prostheses three months after prosthesis installation, training for activities of daily living, simulated training for vocation (χ² > 6.520, P < 0.05); willingness to participate in social activities with prostheses, attitude of other persons towards their prostheses, support of family members, work status, familiarity with the policies of welfare, and the current physical condition (χ² > 13.152, P < 0.01). ConclusionFactors of amputee, prosthetic fitting, prosthetic training, and environment and social policy may relate to the abandonment of upper limb prostheses, which are needed to improve in an accurate way.

Objective:To investigate the role of circular RNA (circRNA) circSEPT9 in the radioresistance of glioma and its molecular mechanism.Methods:Pathological samples were collected from 40 glioma patients who underwent surgery and postoperative radiotherapy in the First Affiliated Hospital of Zhengzhou University from January 2019 to January 2022. All patients were divided into the radiation-sensitive and radiation-resistant groups. The expression levels of circSEPT9 were assessed using real-time reverse transcription PCR (RT-qPCR) in two groups. The radiation-resistant glioma cell U251R was constructed based on human glioma cell U251. The U251R cells were divided into the negative control (si-NC), circSEPT9 knockdown (si-circSEPT9), negative control combined with irradiation (si-NC+4 Gy), circSEPT9 knockdown combined with irradiation (si-circSEPT9+4 Gy), circSEPT9 knockdown combined with control inhibitor and irradiation (si-circSEPT9+NC inhibitor+4 Gy), and circSEPT9 knockdown combined with miR-432-5p inhibitor and irradiation (si-circSEPT9+miR-432-5p inhibitor+4 Gy) groups. The targeting relationship between circSEPT9 and miR-432-5p was verified through dual-luciferase reporter assay. Colony formation assay was employed to assess the survival rate of U251R cells. Flow cytometry was adopted to measure the apoptosis rate. The expression level of circSEPT9 in glioma tissues was statistically analyzed using independent sample t-test. The survival and apoptosis rates in each group were evaluated using one-way ANOVA. Results:The expression level of circSEPT9 was up-regulated in the glioma tissues of patients in the radiation-resistant group (1.00±0.18 vs. 3.25±0.13, P<0.05). Compared to the si-NC group, the U251R cells in the si-circSEPT9 group exhibited a significant reduction in survival fraction and a notable increase in apoptosis rate (9.24±0.83 vs. 19.36±2.13, both P<0.05). After radiation exposure at 4, 6 and 8 Gy, si-circSEPT9 treatment significantly decreased the survival fraction in U251R cells (all P<0.05). Compared with the si-NC+4 Gy group, the apoptosis rate was increased in the si-circSEPT9+4 Gy group (18.83±1.94 vs. 35.23±3.56, P<0.05). Dual-luciferase reporter assay showed that circSEPT9 could target and negatively regulate the expression level of miR-432-5p. Compared with the si-circSEPT9+NC inhibitor+4 Gy group, the survival fraction of U251R was significantly increased in the si-circSEPT9+miR-432-5p inhibitor+4 Gy group ( P<0.05). Conclusion:Knockdown of circSEPT9 enhances the radiosensitivity of glioma cells by regulating cell apoptosis through targeting the miR-432-5p.

Objective:To assess the impact of preoperative short-course radiotherapy combined with neoadjuvant chemotherapy on elderly patients with locally advanced rectal cancer after a 2-year follow-up.Methods:In this retrospective cohort study, we included 446 consecutive cases of elderly patients diagnosed and treated for locally advanced rectal cancer(stage Ⅱ-Ⅲ with T3-T4 and/or positive regional lymph nodes)at the First People's Hospital of Shangqiu city from January 2012 to December 2019.The patients were divided into two groups based on the treatment method: an observation group(107 cases)and a control group(339 cases).The patients in the observation group underwent preoperative short-course radiotherapy combined with neoadjuvant chemotherapy.The regimen included short-term radiotherapy(25 Gy over 1 week in 5 fractions)followed by 4 courses of chemotherapy(CAPOX regimen).On the other hand, the control group received concurrent radiotherapy and chemotherapy.The regimen involved 50 Gy over 5 weeks in 25 fractions and concurrent capecitabine chemotherapy.Afterward, total rectal mesentery resection was performed, and postoperatively, 2 and 6 courses of CAPOX chemotherapy were continued.Follow-up was conducted until 31 December 2021, with the primary observation being the disease-free survival(DFS)of patients in both groups.Secondary observations included overall survival(OS)time, lesion progression-free survival(PFS)time, local recurrence rate, and the rate of acute toxicity events.Cox regression analyses were conducted to compare the factors influencing DFS.Results:Among the 446 patients, 303(67.9%)were male and 143(32.1%)were female.The patients in the observation group were found to be younger and had a higher proportion of Eastern Collaborative Oncology Group(ECOG)physical status score 0 compared to the control group(both P<0.05).Additionally, the two groups differed significantly in terms of MRI T stage, N stage, distance from the external anal verge, rectal mesorectal fascial infiltration, pathological stage, and chemotherapy-to-surgery time interval(all P<0.05).Throughout a mean follow-up period of(20.7±3.5)months, there were 76 deaths, 89 distant metastases, and 32 local recurrences.The results of Kaplan-Meier survival analysis revealed that the observation group had a higher disease-free survival(DFS)rate at 2 years of follow-up compared to the control group[73.8%(79/107) vs.68.1%(231/339), Log-rank χ2=2.676, P=0.041].Additionally, the median DFS time was longer in the observation group[19(12, 22)months]compared to the control group[16(11, 19)months]( Z=2.774, P=0.038).Furthermore, the observation group exhibited a significantly longer OS time[26(21, 33)months]compared to the control group[22(18, 14)months]( Z=2.879, P=0.032).However, the median PFS time was similar in both groups[20(14, 25)months vs.16(12, 21)months]( Z=1.545, P=0.123).The incidence of distant metastasis was 18.7%(20/107)in the observation group and 20.4%(69/339)in the control group(Log-rank χ2=0.341, P=0.708), indicating no significant difference.Similarly, there was no significant difference in the risk of local recurrence between the observation group[9.3%(10/107)]and the control group[6.5%(22/339)](Log-rank χ2=0.996, P=0.318).In terms of adverse reactions, there was no statistically significant difference in the incidence of grade≥3 acute toxic reactions between the two groups[19.6%(21/107) vs.12.1%(41/339), Log-rank χ2=1.661, P=0.148].A multifactorial Cox regression analysis revealed that age( HR=0.586, P=0.005), ECOG score( HR=0.721, P=0.028), MRI T-stage( HR=0.605, P=0.008), rectal mesenteric fascial infiltration( HR=1.649, P=0.012), and distance from the external anal verge( HR=0.638, P=0.041)were associated with DFS. Conclusions:The findings indicate that the combination of preoperative short-course radiotherapy and neoadjuvant chemotherapy in elderly patients with locally advanced rectal cancer demonstrates favorable short-term effectiveness and safety.This approach shows promise in improving outcomes for elderly patients with locally advanced rectal cancer.

Objective To explore the application value of telmisartan combined with calcium dobesilate in patients with non-dipper hypertension complicated with type 2 diabetes mellitus(T2DM).Methods A total of 260 patients with non-dipper hypertension complicated with T2DM in the endocrinology department of our hospital were selected in this study from January 2021 to December 2022.All the patients were randomly divided into telmisartan group(Tel,n=110)and telmisartan+calcium dobesilate group(Tel+Cal-dob,n=150).The blood pressure level,blood pressure rhythm changes,brachial flow mediated dilatation(FMD),carotid radial pulse wave velocity(crPWV),vasomotor factors[nitric oxide(NO),endothelin-1(ET-1),vascular endothelial growth factor(VEGF)]and the incidence of adverse reactions were compared between the two groups.Results There was no significant difference in general data and biochemical indexes between the two groups(P>0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while the dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower than before treatment in both groups(P<0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower in Tel+Cal-dob group than in Tel group(P<0.05).After 3,6 and 12 months of treatment,the conversion rates of dipper blood pressure were higher in Tel+Cal-dob groupthan in Tel group(P<0.05).There was no significant difference in the incidence of adverse effects between the two groups(P>0.05).Conclusion Telmisartan combined with calcium dobesilate is effective in the treatment of patients with non-dipper hypertension complicated with T2DM.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of T-cell lymphoma. Despite the scarcity of reported BIA-ALCL cases in Asia, it is imperative to research early diagnosis. The crucial diagnostic criteria for BIA-ALCL include the presence of ALK - and CD30 + T cells exceeding 10% in the delayed seroma fluid. Furthermore, laboratory tests, such as histological examination of capsulectomies and analysis of clonal T-cell receptor (TCR) gene rearrangements, serve as important auxiliary diagnostic indicators. This article reported the case of a 56-year-old female patient who underwent bilateral breast augmentation with implants over 20 years ago. She presented with hardness, enlargement, and mild discomfort in her left breast. She was admitted to Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine in January 2023. MRI suggested implant rupture. Therefore, bilateral implant removal surgery was performed on February 2, 2023. Pathological examination of the fluid within the capsule of the left implant revealed a small number of ALK - and CD30 + T cells, with monoclonality observed in TCRγ gene rearrangement, indicating early changes suggestive of BIA-ALCL. Long-term follow-up is needed. The authors suggest that patients suspected of BIA-ALCL should undergo TCR gene rearrangement testing in addition to cytological and immunological examinations, which can provide guidance for the diagnosis, treatment, and necessary long-term follow-up of these patients.

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the efficacy of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects who were previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extended or switched TMF treatment for 48 weeks. Efficacy was evaluated based on virological, serological, biological parameters, and fibrosis staging. Statistical analysis was performed using the McNemar test, t-test, or Log-Rank test according to the data. Results:593 subjects from the initial TMF group and 287 subjects from the TDF group were included at week 144, with the proportions of HBV DNA<20 IU/ml at week 144 being 86.2% and 83.3%, respectively, and 78.1% and 73.8% in patients with baseline HBV DNA levels ≥8 log10 IU/ml. Resistance to tenofovir was not detected in both groups. For HBeAg loss and seroconversion rates, both groups showed a further increase from week 96 to 144 and the 3-year cumulative rates of HBeAg loss were about 35% in each group. However, HBsAg levels were less affected during 96 to 144 weeks. For patients switched from TDF to TMF, a substantial further increase in the alanine aminotransferase (ALT) normalization rate was observed (11.4%), along with improved FIB-4 scores.Conclusion:After 144 weeks of TMF treatment, CHB patients achieved high rates of virological, serological, and biochemical responses, as well as improved liver fibrosis outcomes. Also, switching to TMF resulted in significant benefits in ALT normalization rates (NCT03903796).

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the safety profile of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects that previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extending or switching TMF treatment for 48 weeks. Safety profiles of kidney, bone, metabolism, body weight, and others were evaluated.Results:666 subjects from the initial TMF group and 336 subjects from TDF group with at least one dose of assigned treatment were included at week 144. The overall safety profile was favorable in each group and generally similar between extended or switched TMF treatments from week 96 to 144. In subjects switching from TDF to TMF, the non-indexed estimated glomerular filtration rate (by non-indexed CKD-EPI formula) and creatinine clearance (by Cockcroft-Gault formula) were both increased, which were (2.31±8.33) ml/min and (4.24±13.94) ml/min, respectively. These changes were also higher than those in subjects with extending TMF treatment [(0.91±8.06) ml/min and (1.30±13.94) ml/min]. Meanwhile, switching to TMF also led to an increase of the bone mineral density (BMD) by 0.75% in hip and 1.41% in spine. On the other side, a slight change in TC/HDL ratio by 0.16 (IQR: 0.00, 0.43) and an increase in body mass index (BMI) by (0.54±0.98) kg/m 2 were oberved with patients switched to TMF, which were significantly higher than that in TMF group. Conclusion:CHB patients receiving 144 weeks of TMF treatment showed favorable safety profile. After switching to TMF, the bone and renal safety was significantly improved in TDF group, though experienceing change in metabolic parameters and weight gain (NCT03903796).
