Objective To investigate the suppressive effects of collagen from Cyanea nozakii on adjuvant induced arthritis inrat.Methods Rats with adjuvant arthritis received different do- ses of Cyanea nozakii collagen by intragastric administration for two weeks.Incidence and severity of arthritis were assessed by calculation of mean arthritis index,the concentrations of NO,MDA and activity of SOD in the serum were examined.Results Cyanea nozakii colla- gen at different doses could ameliorate the adjuvant induced arthritis,suppress the concen- trations of NO,MDA and increase the activity of SOD in the serum.Conclusion Cyanea noza- kii collagen has therapeutic efficacy in treatment of adjuvant arthritis rats,and the mecha- nism of Cyanea nozakii collagen is probably related to the antioxidation.

Objective To evaluate the clinical application effect of fracture liaison service(FLS)mode after percutaneous vertebroplasty(PVP)/percutaneous kyphoplasty(PKP)for thoracolumbar fragility fracture.Methods A prospective study was conducted,and 762 patients with thoracolumbar fragility fracture who underwent PVP/PKP in the department of orthopedics in our hospital from January 2018 to May 2021 were included and divided into the control group(374 cases)and the observation group(388 cases)according to the random number table method.Patients in the control group received routine osteoporosis intervention,while the patients in the observation group implemented FLS through Blue Bull Medical Care or Chronic Health APP on the basis of the control group to systematically manage the osteoporosis treatment after discharge.The follow-up lasted for 12 months,and the 8-item Morisky medication adherence scale(MMAS-8)score,pain visual analogue scale(VAS)score,Oswestry disability index(ODI)score and Hamilton depression rating scale(HAMD)score at discharge,and 6 months and 12 months after discharge of the two groups were compared.The incidences of re-fracture and constipation 6 months and 12 months after discharge of the two groups were compared.The Cobb angle and bone mineral density T-value of injured vertebrae 6 months and 12 months after discharge of the two groups were compared.Results There was no statistically significant difference in the MMAS-8 score,VAS score,ODI score or HAMD score at discharge of patients between the two groups(P>0.05).The VAS score,ODI score and HAMD score 6 months and 12 months after discharge in the observation group were lower than those in the control group(P<0.05),the MMAS-8 score in the observation group was higher than that in the control group(P<0.05),and the incidences of re-fracture and constipation in the observation group were lower than those in the control group(P<0.05).There was no statistically significant difference in the Cobb angle of injured vertebrae 12 months after discharge of patients between the two groups(P>0.05).The bone mineral density T-value 12 months after discharge in the observation group was higher than that in the control group(P<0.05).Conclusion The FLS mode can significantly improve the medication compliance of patients,relieve pain,depression and constipation,improve bone mineral density,and significantly reduce the incidence of vertebral re-fracture in patients after vertebral augmentation surgery;however,it has no significant effect on the Cobb angle of injured vertebrae.

Endoplasmic reticulum stress (ERS) is a new pathway inducing cell apoptosis that has been discovered in recent years. This study focused on the protective effect of Liangxue Huayu recipe (LHR) on tumor necrosis factor-alpha (TNF-alpha) and D-GalN-induced hepatocyte apoptosis. It found that TNF-alpha and D-GalN could obviously inhibit hepatocyte proliferation, induce cell apoptosis, and significantly increase free calcium ions in cytoplasms, as well as protein expressions of ERS apoptosis-related signal molecules phosphorylated PERK, phosphorylated elF2alpha, cleaved Caspase-12, GRP78 and CHOP. After the administration of LHR of different concentrations, compared with the TNF-alpha/GalN injury group, LHR could significantly alleviated L02 hepatocyte proliferation, decreased cell apoptosis, inhibited growth of intracytoplasmic free calcium content, and gradually reduced the protein expressions of phosphorylated PERK, phosphorylated elF2alpha, cleaved Caspase-12, GRP78 and CHOP. These findings indicated that LHR has the inhibitory effect on TNF-alpha and D-GalN-induced hepatocyte apoptosis. Its mechanism may be related to down-regulation of ERS apoptosis-related signal molecules phosphorylated PERK, phosphorylated elF2alpha, cleaved Caspase-12, GRP78 and CHOP that maintain calcium homeostasis in endoplasmic reticulum.

OBJECTIVETo identify the phenotype and the gene mutation in a kindred with antithrombin (AT) deficiency.

METHODSImmuno-nephelometry and chromogenic assay were used to detect the plasma level of AT antigen (AT: Ag) and activity (AT: A), respectively. All the seven exons and intron-exon boundaries of AT gene from the propositus were amplified by PCR and direct sequencing of the PCR pro-ducts was performed. Corresponding PCR fragments from the kindred were also sequenced directly. Megaprimer method was used to construct the mutant AT cDNA expressing vector from normal plasmid pCRII AT cDNA. The normal and mutant AT plasmid were transiently transfected into Cos-7 cells and AT: Ag was detected in supernatant and lysate of transfected cell with ELISA.

RESULTSThe plasma level of AT: Ag and AT: A for the propositus were 179 mg/L and 42.3%, respectively. A heterozygous G13328A missense mutation in exon 6 was identified, which led to the substitution of Thr (ACC) 404 for Ala (GCC). The sequencing results from the pedigree suggested that three other members also had the mutation. The level of AT:Ag in supernatant and lysate from cells transfected with mutant AT cDNA was 40% and 68% of that of normal AT cDNA transfected cells.

CONCLUSIONThis is an unreported AT gene mutation in China, which causes type I hereditary antithrombin deficiency and thrombosis in the proposita.

BACKGROUNDSeveral studies have evaluated the association between polymorphisms of encoding excision repair cross complementation group 1 (ERCC1) enzyme and lung cancer risk in diverse populations but with conflicting results. By pooling the relatively small samples in each study, it is possible to perform a meta-analysis of the evidence by rigorous methods.

METHODSEmbase, Ovid, Medline and Chinese National Knowledge Infrastructure were searched. Additional studies were identified from references in original studies or review articles. Articles meeting the inclusion criteria were reviewed systematically, and the reported data were aggregated using the statistical techniques of meta-analysis.

RESULTSWe found 3810 cases with lung cancer and 4332 controls from seven eligible studies. T19007C polymorphism showed no significant effect on lung cancer risk (C allele vs. T allele: odds ratio (OR) = 0.91, 95% confidence interval (CI) = 0.80 - 1.04; CC vs. TT: OR = 0.76, 95%CI = 0.56 - 1.02; CC vs. (CT + TT): OR = 0.96, 95%CI = 0.84 - 1.10). Similarly, there was no significant main effects for T19007C polymorphism on lung cancer risk when stratified analyses by ethnicity (Chinese or Caucasian). No significant association was found between C8092A polymorphism (3060 patients and 2729 controls) and the risk of lung cancer (A allele vs. C allele: OR = 1.03, 95%CI = 0.95 - 1.11; AA vs. CC: OR = 1.08, 95%CI = 0.88 - 1.33; AA vs. (AC + CC): OR = 1.08, 95%CI = 0.88 - 1.31).

CONCLUSIONWe found little evidence of an association between the T1900C or C8092A polymorphisms of ERCC 1 and the risk of lung cancer in Caucasian or Han Chinese people.

China has a high incidence of esophageal cancer，more than 90% of which are esophageal squamous cell carcinoma （ESCC）. Abnormal proliferation，migration and new microvessels of intraepithelial neoplasia cells are the important pathogenic links in the transformation from esophageal intraepithelial neoplasia （EIN） to ESCC. Studies on the progression of esophageal precancerous lesions into esophageal cancer mostly focus on environment and genetic susceptibility，such as inflammatory factors，abnormal vascular endothelial growth factor （VEGF） signaling pathway transduction，p53 gene mutation，and DNA methylation. Some pharmacology studies have confirmed that traditional Chinese medicine （TCM） can inhibit inflammatory factors，regulate abnormal signaling pathways and improve the microenvironment. A large number of patients with esophageal cancer have been found to be in advanced stage，and the 5-year survival rate is low even after active treatment. The quality of life of patients in advanced stage is worrying due to esophageal obstruction and lung infection，and therefore， early prevention is important. Early intervention in patients with esophageal precancerous lesions is in line with clinical needs and embodies the TCM theory of “treating disease before its onset.” The mechanism of action and clinical efficacy of TCM has been gradually confirmed and promoted， with certain clinical significance. To explore simple，economical and effective TCM intervention measures conforms to the clinical diagnosis and treatment standards and the modernization of TCM.

OBJECTIVE: To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy. METHODS: This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30). RESULTS: After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05). CONCLUSION WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy. (Trial registration No. ChiCTR1900023862).

Hepatic cystic echinococcosis is a chronic parasitic disease caused by the infection with the larvae of Echinococcus granulosus in human or animal liver tissues. As a chronic active infectious disease, tuberculous empyema mainly invades the pleural space and then causes visceral and parietal pleura thickening. It is rare to present comorbidity for hepatic cystic echinococcosis and tuberculous empyema. This case report presents a case of hepatic cystic echinococcosis complicated with tuberculous empyema misdiagnosed as hepatic and pulmonary cystic echinococcosis, aiming to improve clinicians’ ability to distinguish this disorder.
