ABSTRACT
The meridian theory is the pioneer of clinical diagnosis and treatment of diseases in Traditional Chinese Medicine (TCM). From Shang Han Lun to Pi Wei Lun, the meridian theory has contributed important theoretical organization materials and clinical practice experience to the establishment of the diagnosis system of external and internal injuries. The acupoints contained in its clinical acupuncture and moxibustion record symptoms, and some laws summarized have been absorbed and used for reference. It shows the positive significance of its exploration in clinical diagnosis and treatment. A system of differentiation and treatment of external and internal injuries with acupuncture has not been formed, even though the meridian theory of TCM has a long history with many areas being explored, such as diseases, acupoints, acupuncture methods and stimulation amount. Therefore, this paper starts from the academic development history of meridians, reviews and analyzes the contribution and limitations of TCM acupuncture and moxibustion in the diagnosis and treatment of internal injury, in order to enlighten the current study and understanding of TCM.

ABSTRACT
With the rapid development of science and technology, more creative methods have been applied to the inheritance mode of traditional Chinese medicine, such as studying the inheritance process of famous doctorsin an objective and rigorous way. The bottleneck of information transmission from famous doctors is to collect data, process data, apply algorithms, analyze and summarize data. The integration of artificial intelligence and big data deep learning algorithm knowledge mapping technology and other technical methods has brought technological innovation for the inheritance of famous doctors. With such development, the team of the research center of TCM grand health intelligence, Institute of Information on Chinese Medicine, China Academy of Chinese Medical Science, has carried out a series of professional application system research in the field of traditional Chinese medicine, centering on the planning and inheritance of famous doctors. We developed the ancient and modern medical case cloud platform, medical big data analysis platform, cloud medical APP, and famous doctor inheritance workstation. In such way, the problems were solved of low efficiency of medical case collection and the lack of objective data support and information barriers in the experience summary of famous doctors. The artificial intelligence techniques are to promote the inheritance of famous doctors' experience and improve the teaching ability and efficiency.

ABSTRACT
Objective The number of confirmed and suspected cases of the COVID-19 in Hubei province is still increasing. However, the estimations of the basic reproduction number of COVID-19 varied greatly across studies. The objectives of this study are 1) to estimate the basic reproduction number ( R 0 ) of COVID-19 reflecting the infectiousness of the virus and 2) to assess the effectiveness of a range of controlling intervention. Method The reported number of daily confirmed cases from January 17 to February 8, 2020 in Hubei province were collected and used for model fit. Four methods, the exponential growth (EG), maximum likelihood estimation (ML), sequential Bayesian method (SB) and time dependent reproduction numbers (TD), were applied to estimate the R 0 . Result Among the four methods, the EG method fitted the data best. The estimated R 0 was 3.49 (95% CI : 3.42-3.58) by using EG method. The R 0 was estimated to be 2.95 (95% CI : 2.86-3.03) after taking control measures. Conclusion In the early stage of the epidemic, it is appropriate to estimate R 0 using the EG method. Meanwhile, timely and effective control measures were warranted to further reduce the spread of COVID-19.

ABSTRACT
Objective@#To evaluate the effect of the "Interner Plus-based AIDS Comprehensive Prevention Service System" among MSM in Guangzhou, during 2010-2017, using a dynamic compartmental model.@*Methods@#A dynamic compartmental model was developed to describe the HIV situation among MSM in Guangzhou. This model was parameterized on data from published literature or surveillance programs from the Guangzhou CDC. The Matlab 7.0 software was used for coding and analysis on collected data. HIV prevalence was analyzed among MSM under the status quo data and estimated the impact by the "Internet Plus" AIDS prevention services project.@*Results@#HIV prevalence would have increased to 22.75% in 2017, and the total number of new HIV infections would have been 11 038, from 2010 to 2017, using the data status quo. Under the Guangzhou "Internet Plus" AIDS prevention services project, the prevalence of HIV among MSM from 2010 to 2017 was estimated to be 8.44%, 9.68%, 10.65%, 11.34%, 11.73%, 11.83%, 11.71% and 11.43% in Guangzhou, which were similar to the surveillance data. The total number of new infections in the past 8 years under the "Internet Plus" scenario was estimated to be 4 009. The "Internet Plus" program would have prevented 7 029 (63.68%) new infections during 2010-2017 as compared to the number, status quo.@*Conclusions@#The fitting result of dynamic compartmental model seemed more reasonable, which was applicable to predict HIV epidemic among MSM in Guangzhou, suggesting that the increase of HIV prevalence had been curbed since the "Internet Plus" project which was launched in 2010, and the "Interner Plus-based AIDS Comprehensive Prevention Service System" had achieved the purpose as planned, epidemiologically.
ABSTRACT
Objective To establish a dynamic compartmental model to predict the impact of HIV testing and treatment and pre-exposure prophylaxis (PrEP) on the annual incidence of HIV infection in men who have sex with men (MSM) in China from 2018 to 2037.Methods A dynamic compartmental model was developed to describe the HIV epidemic in MSM in China.The model was parameterized using data from the literature available.We used MATLAB 7.0 software for data simulation and graphics rendering.We analyzed HIV transmission among MSM and estimated the impact of expanded HIV testing and treatment and PrEP on HIV elimination in MSM.Results Under the current policy,the number of new HIV infections would reach 770 000,the infection rate would reach 11.1％ and the incidence rate would reach 0.72/100 person years in MSM in the next 20 years.Under the 90％-90％-90％ goal,440 000 new infections (57.7％) would be reduced,the HIV infection rate would decline to 5.7％ and the incidence rate would decline to 0.24/100 person years in the next 20 years,but it is still unlikely to achieve the goal of HIV elimination.With 100％ PrEP compliance,the required PrEP coverage rates for achieving HIV elimination in the next 10,15 and 20 years would be 65％,32％ and 19％,respectively.Conclusion It is necessary to strengthen the comprehensive intervention in MSM,continue to expand HIV testing and treatment,and improve PrEP adherence and coverage to further control and eliminate the epidemic of HIV/AIDS in MSM.
ABSTRACT
Objective: The burden of noncommunicable diseases (NCDs) is increasing in China, together with economic development and social changes. The prevalence of risk factors for NCDs, such as overweight/obesity, hypertension, diabetes, and dyslipidemia, is reported to be high even among poor residents of rural areas. We aimed to investigate the prevalence of hypertension among elderly adults in rural Northeast China and the proportion with controlled hypertension among those on antihypertensive medication (hypertension control rate). We also aimed to examine the association of hypertension control with health facilities that provide treatment.Methods: We conducted a community-based cross-sectional study in six rural villages of Northeast China from February to early March, 2012. We interviewed 1593 adults aged 50–69 years and measured their blood pressure. We examined the differences in mean blood pressure between participants who obtained antihypertensive medication from village clinics and those who obtained medication from other sources, using analysis of covariance adjusted for several covariates.Results: The prevalence of hypertension among participants was as high as 63.3%, but the hypertension control rate was only 8.4%. Most villagers (98.1%) were not registered in the chronic disease treatment scheme of the public rural health insurance. The mean systolic blood pressure, adjusted for the covariates, of participants who obtained antihypertensive medication from village clinics was significantly lower than that of participants who obtained medication from township hospitals (by 16.5 mmHg) or from private pharmacies (by 7.3 mmHg).Conclusion: The prevalence of hypertension was high and the hypertension control rate low among elderly villagers during the cold season. As treatment at village clinics, which villagers can access during the cold season seems to be more effective than self-medication or treatment at distant hospitals, improving the quality of treatment in village clinics is urgently needed.

ABSTRACT
Objective This study aims to investigate the effect of geranylgeranyltransferaseⅠ (GGTase-Ⅰ) on the proliferation and growth of tongue squamous cancer cells. Methods Three small interfering RNAs (siRNAs) were designed on the basis of the GGTase-Ⅰ sequence in GeneBank. These siRNAs were then transfected into tongue squamous cancer cells Cal-27. The mRNA and protein expression of GGTase-Ⅰ and RhoA were examined by real-time quantitative polymerase chain reaction and Western blotting, respectively. The expression of Cyclin D1 and p21 were examined by Western blotting. The proliferation and growth ability were analyzed by cell counting kit-8 assay and flow cytometry. Results The mRNA and protein expression of GGTase-Ⅰ in Cal-27 was reduced significantly after the GGTase-Ⅰ siRNAs were transfected (P<0.05). No significant difference in RhoA mRNA and protein expression was detected (P>0.05). Cyclin D1 expression decreased, whereas p21 expression increased significantly. The cell cycle was altered, and the growth-proliferative activity was inhibited (P<0.05). Conclusion GGTase-Ⅰ siRNA can inhibit the expression of GGTase-Ⅰ and the proliferative activity of tongue squamous cancer cells. GGTase-Ⅰ may be a potential target for gene therapy in tongue squamous cell cancer.
ABSTRACT
Objective To investigate the effect of the language intervention to reduce patients′discomfort during a colonoscopy examination. Methods A total of 72 subjects who accepted a colonoscopy process in the Digestive Endoscopy Department of the Dalian Central Hospital from September 2014 to December 2015 were divided by random number table method into two groups, 38 for the control group and 34 for the observation group. The control group adopted routine nursing care, while the observation group adopted the language intervention besides the routine nursing care, in accordance with the implementation steps of language intervention for patients who accepted the colonoscopy examination, which means the four stages , the four positions and the four methods. The first stage: the enteroscope entered the anus and arrived the rectum , applied the deep breathing with anal movement method . The second stage: from the rectum to the sigmoid colon, used the induce distraction method. The third stage: stimulated the patients′ excitement at the junctional area of descending colon and transverse colon (the spleen area). The fourth stage: at the junctional area of transverse and ascending colon (the liver ares), used the continuous excitation method. In each stage, individualized language intervention and psychological nursing were given to every patient in the observation group. The cooperating effect of the two groups were evaluated. Results The frequency of pain, the pain scores,the frequency of pressing and the average insertion time of the control group respectively were (8.68 ± 0.83) times,(45.08 ± 6.66) points, (5.73±0.75) times,(372.26±31.77) s, while the observation group were (4.53±0.38) times,(17.07± 3.01) times,(2.05±0.38) times,(268.61±14.51) s, less than the control group ,the t value respectively were 3.81,27.17,3.51,4.66, and the difference was significant (P<0.01 or 0.05).

ABSTRACT
Objective To assess the application value of trans-vaginal ultrasound and real-time sono-elastography in assessing the risk of preterm birth in pregnant women. Methods A total of 108 pregnant women who received prenatal examination at Beijing Obstetrics and Gynecology Hospital from January to November 2017 were included. Based on the presence of threatened premature or preterm labor or not, they were divided into a study group (n=29, with threatened premature or preterm labor) and a control group (n=79, with no threatened premature or preterm labor). Cervical length (CL) was measured by trans-vaginal ultrasound, and the following three cervical elasticity indexes were obtained by sono-elastography: the entire cervical strain rate (CS), the internal cervical os strain rate (IS), and external cervical os strain rate (ES). Independent samples t-test was used to analyze the difference in the above indexes between the two groups. Receiver operating characteristic (ROC) curve analysis was performed to assess the value of the above indexes in predicting the risk of preterm birth.Results CL was significantly lower[(2.94±0.66)cm vs(3.91±0.71)cm]and IS was significantly higher [(0.53±0.28)% vs (0.47±0.20)%] in the study group than in the control group (t=6.436, 3.406,both P<0.05).CS and ES in the study group were higher than those in the control group[(0.40±0.30)% vs (0.24±0.19)%,(0.74±0.39)% vs(0.73±0.37)%],but the differences were not statistically significant(t=1.365, 0.207, both P>0.05). ROC curve analysis indicated that CL, CS, IS, and ES performed differently in assessing the risk of preterm birth in pregnant women [area under the ROC curve (AUC): 0.156, 0.558, 0.689, 0.499]. The AUCs of CS and IS were greater than 0.50, and the AUC of IS was larger than those of other indexes. Using 0.30% as a cut-off for IS, its sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 66.7%, 79.3%, 71.1%, 55.4%, and 80.2%, respectively. Conclusions Cervical tissue elasticity indexes obtained by sono-elastography can be used to assess pregnant women at different gestational ages and predict the risk of preterm birth feasibly. IS is more useful than other indexes in predicting early or asymptomatic preterm birth.

ABSTRACT
Objective:To study relationship between B10 cells and the incidence of autoimmune diabetes in nonobese diabetic mice. Methods:20 NOD/LT female mice of 6 week old were cultured in normal culture to 30 weeks,and the mice were divided into two groups according the mice’s blood glucose,serum creatinine and body weight detected at their 30 weeks old. IL-10 levels in spleen tissues of the two groups were detected by enzyme-linked immunosorbent assay. We used flow cytometry to detect the proportion of B10 cells in the spleen of mice in the two groups. NOD/LT mice were randomly divided into control group and B10 group. The B10 cells were inoculated in B10 groups,their blood glucose were detected when they were 10,15,20,25 and 30 weeks old. Results: The blood glucose and serum creatinine levels were significantly higher in the group than that in the autoimmune diabetes group (P< 0. 05),and the body weight was significantly lower than that in the autoimmune diabetes group (P<0. 05). The level of IL-10 in the spleen tissues of the autoimmune diabetes mice was significantly higher than that in the non autoimmune diabetes group. The content of B10 cells in the spleen of the mice with autoimmune diabetes mellitus was significantly higher than that in the non autoimmune diabetes group. When mice at the age of 10,15 weeks,the incidence of autoimmune diabetes in B10 group was significantly lower than that in the control group,but the incidence of autoimmune diabetes in B10 group was significantly higher than that in control group at 20,25 and 30 weeks. Conclusion:The over accumulation of B10 cells may be one of the reasons for the further development of autoimmune diabetes in NOD mice.
