Chinese Journal of Tissue Engineering Research 2020;24(29):4638-4642
BACKGROUND: Both thunder-fire moxibustion and electroacupuncture can effectively improve the related symptoms of knee osteoarthritis. At the same time, the two treatments have the advantages of simple operation, low cost, strong practicability and so on. OBJECTIVE: To observe the difference in curative effect between thunder-fire moxibustion combined with electro-acupuncture and celecoxib capsule in the treatment of cold-wet knee osteoarthritis. METHODS: Seventy-two patients with cold-wet knee osteoarthritis, including 35 males and 37 females, who were treated in Ruikang Hospital affiliated to Guangxi University of Chinese Medicine from June 2017 to December 2018, were randomly divided into two groups: observation group (n=35) received thunder-fire moxibustion (once a day) combined with electroacupuncture treatment (once a d); and control group (n=37) was given oral celecoxib capsule (once a day). Treatment in each group lasted for two sessions of 14 days each with a 2-day break. Visual analogue scale score, Western Ontario and McMaster Universities (WOMAC) score, and joint fluid related inflammatory index were detected before and after treatment. The effective rate of TCM syndrome was evaluated. A 1-month follow-up was carried out after treatment. The experimental protocol was approved by the Ethics Committee of Ruikang Hospital affiliated to Guangxi University of Chinese Medicine (KY2017-005). RESULTS AND CONCLUSION: There were no adverse reactions in the two groups. The visual analogue scale scores and WOMAC scores (pain, stiffness and function) in the observation group were significantly reduced after treatment and during the follow-up (P < 0.05). The visual analogue scale scores and WOMAC scores (pain and stiffness) in the control group were significantly reduced after treatment and at the end of the follow-up (P < 0.05). Compared with the control group, the visual analogue scale scores and WOMAC scores (pain, stiffness and function) were significantly lower in the observation group after treatment and during the follow-up (P < 0.05). The levels of interleukin-6 and tumor necrosis factor-α in the two groups were significantly lowered after treatment, and a more significant reduction was observed in the observation group (P < 0.05). The total effective rate of treatment in the observation group was higher than that in the control group (97.1% vs. 81.1%, P < 0.05). Therefore, electroacupuncture combined with thunder-fire moxibustion has favorable outcomes in the treatment of cold-wet knee osteoarthritis accompanied by less adverse reactions. Moreover, electroacupuncture combined with thunder-fire moxibustion is superior to celecoxib capsule in terms of curative effect persistence.

To investigate the susceptibility of Chukars to duck avian influenza virus H9N2 and explore their role in interspecies transmission of influenza viruses. Chukars were inoculated with duck avian influenza viruses H9N2. The present study demonstrated that inflammatory lesions and virus antigen were present in the trachea, bronchus, and parabronchus, and the viruses could be isolated from throat swabs and lung tissue homogenate supernatants. At 14 d post virus inoculation, anti-H9 influenza virus antibody in the serum was detected. The results indicated that Chukars are susceptible to duck avian influenza virus and serve as an intermediate host, thereby facilitating viral gene evolution and supporting the need for continued surveillance of epidemiology and evolution of the influenza virus in Chukars.

3. Establishment of lineage tracing method of mice small intestinal stem cell and application in radiation injury
Medical Journal of Chinese People's Liberation Army 2015;40(5):349-353
Objective To establish a lineage tracing method with Lgr5-EGFP-CreERT2/ROSA26-stop-EYFP mouse for observing the role of Lgr5+ intestinal stem cells in the renovation of small intestine tissue, and investigate the effects of radiation on the reconstruction of small intestinal stem cell tissue. Methods-Lgr5-EGFP-CreERT2/ROSA26-stop-EYFP mice were identified by genotype analysis. Tamoxifen was used to induce the expression of fluorescent protein in mice. The differentiation of intestinal stem cells induced by Tamoxifen was observed by laser confocal microscopy. Lgr5-EGFP-CreERT2/ROSA26-stop-EYFP mice were irradiated with60Co γ-rays, and the effects of irradiation on the reconstruction of small intestinal stem cell tissue were examined. Results-Double positive mice were obtained by identification of Lgr5 gene (174bp) in DNA extraction from the mice tail with PCR method. In mice treated with single injection of Tamoxifen (100mg/kg), it was observed by laser confocal scanning microscopy that the Lgr5+ intestinal stem cells started dividing at the 5th day after inducement, reached the top of the villi at the 7th day, fluorescence appeared in a few of whole intestinal villi at the 14th day, and spread over more intestinal villi with dense fluorescence at the 45th day. However, in mice exposed to 15Gy irradiation, the intestinal villi fell off seriously without fluorescence in crypts. Conclusion-The lineage tracing model of intestinal stem cell has been successfully established and then used to evaluate the irradiation injuries to intestinal stem cells.

BACKGROUNDEpidemiologic studies have reported inconsistent results regarding tea consumption and the risk of pancreatic cancer. This study aimed to investigate whether tea consumption is related to the risk of pancreatic cancer.
METHODSWe searched Medline, EMBASE, ISI Web of Science, and the Cochrane library for studies published up to November 2013. We used a meta-analytic approach to estimate overall odds ratio (OR) and 95% confidence interval (CI) for the highest versus the lowest tea consumption categories.
RESULTSThe summary OR for high versus no/almost never tea drinkers was 1.04 (95% CI: 0.91-1.20), with no significant heterogeneity across studies (P = 0.751; I(2) = 0.0%). The OR was 0.99 (95% CI: 0.77-1.28) in males and 1.01 (95% CI: 0.79-1.29) in females. The OR was 1.07 (95% CI: 0.85-1.34) in Asian studies, 1.05 (95% CI: 0.84-1.31) in European studies, and 0.98 (95% CI: 0.72-1.34) in the US studies. The OR was 0.87 (95% CI: 0.69-1.10) without adjustment for a history of diabetes and 1.16 (95% CI: 0.97-0.39) after adjustment for a history of diabetes. The OR was 0.90 (95% CI: 0.72-1.12) without adjustment for alcohol drinking and 1.16 (95% CI: 0.96-1.39) after adjustment for alcohol drinking. The OR was 0.97 (95% CI: 0.76-1.25) without adjustment for BMI and 1.07 (95% CI: 0.87-1.31) after adjustment for BMI.
CONCLUSIONThis systematic meta-analysis of cohort studies dose not provide quantitative evidence that tea consumption is appreciably related to the risk of pancreatic cancer, even at high doses.

OBJECTIVE: To explore the changes of pulmonary hemodynamic parameters in pneumoconiosis patients examined by echocardiography and its clinical significance. METHODS: Using simple random sampling method,102 male patients with pneumoconiosis were chosen and divided into simple pneumoconiosis group( 70 cases) and pneumoconiosis combined with chronic pulmonary heart disease( CPHD) group( 32 cases). Forty healthy male volunteers were chosen as the control group. The right heart morphological indexes including the diameters of main pulmonary artery( MPA),right ventricular outflow tract( RVOT),right ventricle( RV),the tricuspid regurgitation velocity and the time velocity integral of the right ventricular outflow tract were measured with echocardiography. The right atrial pressure was estimated and the pulmonary artery systolic pressure( PASP),the pulmonary vascular resistance( PVR) and the ratio of pulmonary artery acceleration time / right ventricular ejection time( PAAT / RVET) were calculated. RESULTS: The diameters of MPA,RVOT and RV in pneumoconiosis combined CPHD group were longer than those of the control group and simple pneumoconiosis group( P <0. 05). The RVOT diameter of simple pneumoconiosis group was longer than that of the control group( P < 0. 05). The indexes of PASP and PVR in pneumoconiosis combined CPHD group were higher than those of the control group and simple pneumoconiosis group,respectively( P < 0. 05). The indexes of PASP and PVR in simple pneumoconiosis group were higher than those of the control group( P < 0. 05). The indexes of PAAT / RVET in pneumoconiosis combined CPHD group and simple pneumoconiosis group were lower than that of the control group,respectively( P < 0. 05). There was no statistical significance difference found in MPA and RV diameters between simple pneumoconiosis group and the control group( P > 0. 05). CONCLUSION: Our results indicate that monitoring the pulmonary hemodynamic parameters of pneumoconiosis patients by using echocardiography can provide basis for planning early intervention measures in clinic.

OBJECTIVE: To explore the exercise capacity of patients with occupational pneumoconiosis with varying degrees of pulmonary dysfunction. METHODS: A total of 488 hospitalized occupational pneumoconiosis patients were selected as study subjects using the judgment sampling method and examined for pulmonary function test and cardiopulmonary exercise test(CPET). Among them, 272 patients with normal lung function were assigned as the control group, and 216 patients with abnormal lung function as the case group. The case group was divided into mild, moderate and severe pulmonary dysfunction subgroups according to the forced expiratory volume in one second/predicted value ratio(FEV_1%pred).RESULTS: The FEV_1%pred, maximal voluntary ventilation(MVV), maximum exercise tidal volume(VT_(max)), breathing reserve(BR), maximal Watt(W_(max)), maximum oxygen uptake(VO_(2max)) and anaerobic threshold(AT) in patients of the case group were lower than that in the control group(all P<0.05). The FEV_1%pred, MVV, VT_(max), W_(max), and VO_(2max) in patients in the 3 subgroups of abnormal lung function were decreased(all P<0.05) compared with the control group. The VO_(2max) and AT decreased in the case group with the increase of the degree of pulmonary dysfunction(P<0.05). The FEV1%pred, MVV, maximal exercise minute ventilation and VT_(max) of the study subjects were positively correlated with VO_(2max) and AT(all P<0.01), but the BR had no correlation with VO_(2max) and AT(all P>0.05). CONCLUSION: The more serious the abnormal degree of pulmonary function in the patients with occupational pneumoconiosis, the more obvious the decline of their exercise ability, showing a dose-effect relationship.

9.Role of chemotherapy in stage IIb nasopharyngeal carcinoma.
Chinese Journal of Cancer 2012;31(12):573-578
The efficacy of neoadjuvant chemotherapy and adjuvant chemotherapy on stage IIb nasopharyngeal carcinoma(NPC) remains unclear. Conventional two-dimensional radiotherapy combined with concurrent chemotherapy can improve the overall survival, progression-free survival, recurrence-free survival, and distant metastasis-free survival of patients with stage IIb NPC. Intensity-modulated radiotherapy without concurrent chemotherapy also provides good outcomes for patients with stage IIb NPC. This article summarizes the features of stage IIb NPC and reviews the role of chemotherapy in this subgroup of NPC.

10.Application progress of mesenchymal stem cells in islet transplantation for type 1 diabetes mellitus
Organ Transplantation 2024;15(2):214-219
Islet transplantation is considered as one of the most effective approach for type 1 diabetes mellitus, although its efficacy is limited by several factors. Anoxia, stress and rejection occurring during the isolation, culturing and transplantation of islets may have impact on the outcome of the islet transplantation. Due to the biological properties such as anti-inflammation, angiogenetic promotion and immune regulation, mesenchymal stem cells (MSCs) are all the way focused by researchers. Additionally, exosome, a derivative of MSC, also plays an import role in regulating anoxia-induced oxidative stress modulation, angiogenetic promotion, and immune regulation. MSC-based islet transplantation may be a useful therapeutic tool in treating type 1 diabetes. Therefore, in this review, the potential effect of MSC prior and posterior to the operation of the islet transplantation, its clinical application as well as its limitations were reviewed, aiming to offer insights into the future application of islet transplantation in treating type 1 diabetes.
