Moyamoya disease is a progressive cerebrovascular occlusive disease, which is characterized by the formation of abnormal vascular network at the brain base. It is an important cause of stroke in children and adults. Now, the etiology of moyamoya disease is not clear. This article reviews its pathogenesis from 3 aspects, including genetic factors, angiogenesis, and immune inflammation.

Objective To investigate the clinical efficacy of acupuncture at point Houxi (SI3) in treating cervical spondylotic vertebral arteriopathy. Method Three hundred and fourteen patients with cervical spondylotic vertebral arteriopathy were randomly allocated to a treatment group of 158 cases and a control group of 156 cases. The treatment group received acupuncture at points Houxi, Fengchi (GB20), Wangu (GB12), Tianzhu (BL10) and cervical Huatuo jiaji (Ex-B2) points and the control group, no acupuncture at point Houxi. The therapeutic effects were evaluated in the two groups after treatment. The recurrence rates were compared at the one-year follow-up. Result The total efficacy rate was 94.9% in the treatment group and 87.2% in the control group; there was a statistically significant difference between the two groups (P<0.05). The recurrence rate was 5.1% in the treatment group and 13.6% in the control group at the one-year follow-up. There was a statistically significant difference in the recurrence rate between the two groups (P<0.05). Conclusion Acupuncture at point Houxi and other combined points has a better therapeutic effect on cervical spondylotic vertebral arteriopathy. It can markedly reduce the recurrence rate in the patients.

Aim To evaluate whether the combination of polypeptide AP25 and docetaxel is more efficient in treating experimental breast cancer,than either reagent used alone,and to offer suggestions for clinical use. Methods An experimental breast carcinoma model was set up to investigate the anti-tumor effects of AP25 and docetaxel combination.The Q value was caluculat-ed by Guinness rules and the anti-tumor effects of the combination of polypeptide AP25 and docetaxel were e-valuated.Results The treatment by the combination of polypeptide AP25 and docetaxel showed a better tumor inhibition rate.The combination of AP25 20 mg ·kg -1 and docetaxel 10 mg·kg -1 significantly inhibi-ted the tumor growth with 0.85 1.15,showing a synergistic effect.Conclusions The combination of AP25 and docetaxel can significantly in-hibit the tumor growth with a synergistic effect and de-crease the dose of chemotherapy.

Ischemia-reperfusion injury (IRI) is a pathophysiological process, which widely exists in organ transplantation and surgery. IRI is mainly manifested with hypoxia injury of organs or tissues during the ischemia period, which could be further aggravated after reperfusion. Ischemia-reperfusion induces tissue cell injury, releases damage-associated molecular pattern and further activates multiple immune cells via pattern recognition receptor, leading to aseptic inflammation and aggravating tissue injury. Cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS), as a critical member of pattern recognition receptor, could activate the stimulator of interferon genes (STING) signal pathway and play an important regulatory role in innate immune response. At present, increasing evidences have shown that cGAS-STING signal pathway plays a significant role in organ IRI. In this article, STING signaling pathway, its role and mechanism in IRI of different organs were reviewed, aiming to provide novel ideas for clinical interventions.

Gallbladder polypoid lesions (GPLs) refer to any elevated lesion of the mucosal surface of the gallbladder wall, and the prevalence is estimated to be between 0.9% and 12.1%. GPLs include benign polyps and malignant polyps. Benign polyps are further classified as non-neoplastic polyps and neoplastic polyps. Cholesterol polyps are the most common benign polyps and adenocarcinoma is the main type of malignant polyp. Hepatitis B virus infection, liver function abnormalities, dyslipidemia, and obesity are the main risk factors for GPLs. Studies of biological mechanisms have focused on malignant gallbladder polyps, the development of which is regulated by hormone levels in vivo, gut microbiota, inflammation, oxidative stress, Salmonella typhimurium, and related molecules. Diagnostic modalities include chemical examination and imaging examination, with imaging examination currently being the mainstay. Treatment of patients with GPLs is based on the presence or absence of symptoms, age, size of the polyps, tendency of the polyp to increase, and risk factors for symptomatic malignancy to determine whether surgery should be performed.

Objective To evaluate the diagnostic value of expression of MG7-Ag diflferentiation and guidance of follow-up mucosal biopsy in the patients with suspected malignanct gastric ulcer.Methods The expression of MG7-Ag in 58 patients who were suspected as having malignant gastric ulcer under routine endoscopy was studied by immuno-histochemical staining.The follow-up endoscopy was pefformed 1 to 72 weeks(mean 7 weeks)later and biopsy was taken.Results There were 19 cases of gastric carcinoma in 30 patients with positive MG7-Ag expression(63.3%)and only 5 in 28 patients with negative MG7-Ag expression(P＜0.01).Conclusion The positive expression of MG7-Ag is correlated with gastrie carcinoma in patients with suspected malignant gastric ulcer.

AIM: To investigate the levels of mRNA, protein of glucosylceramide synthase (GCS) and caspase 3 in the drug resistance induced by doxorubicin in human gallbladder carcinoma cell line GBC-SD, the effect of ceramide metabolism in this process was examined. METHODS: Human gallbladder carcinoma cell line GBC-SD was treated by doxorubicin at concentration of 200 ?g/L for 12 weeks (named GBC-SD12). Cytotoxicity, mRNA and protein of GCS were measured on 1st week, 4th week and 12th week by MTT assays, RT-PCR or Western blotting. The levels of caspase 3 were measured by spectrofluorometry. RESULTS: A 3.8-fold increase in drug resistance to doxorubicin in GBC-SD12 was observed. Up-regulation of GCS mRNA and protein were also detected in GBC-SD12 (P

Objective To evaluate concomitant anatomical hepatectomy and inferior vena cava (IVC) reconstruction for hepatic cancer. Methods Between Aug 2004 and Jul 2005, three patients with intrahepatic cholangiocarcinoma and two patients with hepatocellular carcinoma suspected to invade the wall of IVC underwent concomitant hepatectomy, IVC resection and reconstruction under portal triad clamping (PTC), total vascular exclusion(HVE) without venovenous bypass. The retrohepatic IVC was repaired by primary suture (n = 2), a Gore-Tex patch (n = 1), and a ringed ePTFE graft ( n = 1). Results Surgery was successful in all cases without operative death. The mean operative time was 345 min (range 300 ~ 450 min) ,and the mean intraoperative blood loss was 1375 ml (range 1200 ~ 1800 ml). The cumulated mean PTC and HVE times were 19 min and 21.2 min respectively. Postoperative complications included pleural effusion in one needing thoracentesis, bile leakage and ascites in one each. During the follow-up, one patient died at 9 months due to recurrence, and the remaining 4 patients were alive at the follow-up of 4 to 15 months. Conclusions Concomitant hepatectomy with IVC resection offers hope for patients with hepatic tumors involving the IVC, who would otherwise have a dismal prognosis.
