ObjectiveTo establish a mouse model of basilar artery dolichoectasia （BAD） and explore the mechanism of modified Tongqiao Huoxuetang （JTQHX） in regulating BAD via phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodSixty C57/BL6 female mice were randomized into sham operation （injected with 10 U·mL^-1 inactivate elastase）， model， atorvastatin calcium tablets （2.6 mg·kg·d^-1）， and low- and high-dose （crude drug 3.4， 17 g·kg^-1·d^-1， respectively） JTQHX groups. The mouse model of BAD was established by injection with 10 U·mL^-1 elastase. After 14 days of modeling， the sham operation group and model group were administrated with equal volumes of pure water by gavage， and other groups with corresponding drugs for 2 months. The levels of interleukin-6 （IL-6） and calpain （LpA） in the serum were measured by enzyme-linked immunosorbent assay （ELISA）. Verhoeff 's Van Gieson （EVG） staining was employed to observe the pathological changes of blood vessels. Terminal-deoxynucleotidyl transferase mediated nick end labeling （TUNEL） was employed to examine the apoptosis rate of vascular smooth muscle cells （VSMCs）. Image Pro Plus was used to observe and calculate the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle of the basilar artery vessels in mice. Western blot was employed to determine the expression levels of PI3K and Akt in the vascular tissue. ResultCompared with the sham operation group， the model group showed lowered IL-6 level （P<0.01）， no significant change in LpA level， increased apoptosis of VSMCs （P<0.01）， and increased curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.01）. Furthermore， the modeling up-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01） and aggravated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. Compared with the model group， 2 months of treatment with JTQHX elevated the IL-6 level （P<0.01）， reduced the apoptosis of VSMCs （P<0.01）， decreased the curvature index， elongation length， percentage increase in vessel diameter， and curvature angle （P<0.05， P<0.01）， and down-regulated the protein levels of PI3K and Akt in blood vessels （P<0.01）. In addition， the treatment alleviated the destruction of the inner elastic layer， atrophy of the muscular layer， and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. ConclusionJTQHX inhibits the elongation， expansion， and curvature of basilar artery vessels and alleviates the pathological changes by reducing the apoptosis of VSMCs and down-regulating the expression of PI3K/Akt pathway.

Objective To systematically review the effect of high blood flow restriction training(BFRT)on patients after anterior cruciate ligament reconstruction(ACLR). Methods Relevant literature was searched in PubMed,Web of Science,Embase,Cochrane Library,CNKI,CBM,Wan-fang data,and VIP databases using subject term search methods from the inception to May 1st,2024.The meth-odological quality of the included literatures was assessed using Physiotherapy Evidence Database(PEDro)scale,and relevant data were extracted for systematic review. Results A total of seven articles were finally included,involving 183 subjects from six countries.The intervention sites were mainly hospital rehabilitation departments and rehabilitation centers.The publication dates ranged from 2016 to 2023.In BFRT group,lower limbs were compressed during conventional rehabilitation training,with in-termittent of 0.5 to 2 minutes or without deflation.BFRT would increase muscle strength,muscle hypertrophy,and improved knee joint function.Total duration of intervention and training intensity affected the improvement. Conclusion High BFRT can improve the condition of the muscles around the knee joint and promote functional recovery after ACLR.To ensure the safety and effectiveness of the training,low-intensity strength training should be em-ployed,with 15 to 30 repetitions per set,four to five sets per session,two to three sessions per week,and a total training duration of at least three weeks.

Objective To observe the effect of abdominal acupuncture in treating allergic rhinitis(AR).Methods Twenty-seven AR patients who attended Fangshan Hospital,Beijing University of Chinese Medicine from August to October 2022 were selected.They were divided into treatment group(15 cases)and control group(12 cases)according to randomized numerical table method.The treatment group received abdominal acupuncture.The control group at the same point was used one-time sterile cannula acupuncture to simulate acupuncture,but no needle was inserted into the acupoint.Two groups were treated,3 times a week for 4 weeks.The visual analogue scale(VAS),rhinoconjunctivitis quality of life questionnaire(RQLQ),Pittsburgh sleep quality index(PSQI)scores,and the histamine(HIS),leukotriene D4(LTD4),immunoglobulin E(IgE)levels were compared between two groups before and after treatment.Results At each time point after treatment,the VAS,RQLQ,PSQI scores and HIS,LTD4,IgE levels of patients in treatment group were significantly lower than those before treatment(P<0.05).There were no statistically significant differences in VAS,RQLQ,and PSQI scores,the HIS,LTD4,and IgE levels after 2-week treatment in both groups(P>0.05).After 4-week treatment and follow-up 4-week,the VAS,RQLQ,and PSQI scores,the HIS,and LTD4 levels in treatment group were significantly lower than those in control group(P<0.05).Conclusion Abdominal acupuncture has good therapeutic effect on AR and significantly improves life quality of the patients,which can reduce the levels of HIS,LTD4 and IgE.The therapy is worthy of clinical application.

Molar-incisor hypomineralization (MIH) is defined as an enamel mineralization defect caused by systemic factors, which is characterized by demarcated opacities. These opacities are liable to result in brittle hypomineralized enamel breakdown, which expediting the eventual development of cavities, even tooth loss. Early diagnosis and prompt intervention are essential. The MIH scoring system based on the diagnostic criteria of the European Academy of Paediatric Dentistry (EAPD) is internationally recognized. This system is particularly helpful to diagnose and evaluate the MIH, as well as conductive to the performance of epidemiological investigations. This paper gives a presentation on the EAPD judgment criteria and scoring system as well as their applications, based on the current situation of MIH studies and our findings of MIH epidemiological investigation.

Objective:To explore the safety and efficacy of immune checkpoint inhibitors(ICI)for patients with tumor recurrence after liver transplantation(LT).Methods:A single-center retrospective study was conducted for 6 recipients of tumor recurrence after LT on a therapy of ICI admitted into Shulan(Hang Zhou)Hospital from September 2015 to June 2018.The authors examined the occurrences of graft rejection and clinical outcomes of overall response rate, progression-free survival and overall survival after dosing of PD-1/PD-L1 inhibitors.Results:Six patients enrolled with tumor recurrence on a therapy of ICI undergoing LT due to hepatocellular carcinoma (HCC). Nivolumab (n=4) and duvalizumab (n=2) were administrated.The median session of treatment was 8.3(2-31) cycles.The disease outcomes were stable (3/6, 50%) and progressive (3/6, 50%), The progression-free survival time of 3 disease-controlled patients was 1.5, 16.2 and 18 months and the median survival time after recurrence was 19.75(10.8-37.8) months.Rejection occurred in 1 patients (1/6, 16.7%) and the occurring time of rejection was 28 days after PD-1 inhibitor dosing.After acute rejection, high-dose corticosteroids and immunoglobulin were ineffective and the patient died from acute rejection related liver failure.Conclusions:ICI may be employed as a salvage treatment for tumor recurrence after LT for HCC.Due to a possibility of severe acute rejection, usage should be cautious under close monitoring of liver function.
