Objective To explore the significance of detecting IgH gene rearrangement in diagnosis of non-Hodgkin lymphoma. Methods By using family-specific primers mixtures (VH1,VH2,VH3) for IgH FR3A,FR2A,FR1 genes,clonal IgH gene rearrangement was detected by heminested and multiplex PCR in 44 cases of B-NHL,1 undifferentiated lymphoma,15 T-NHL and 5 lymphonode reactive hyperplasia. Results Clonal IgH gene rearrangement was detected in 36 of 44 B-NHL (positive rate 82%) by using FR3A primers,27 of 44 B-NHL (positive rate 61%) by using FR2A primers. By using FR1 family-specific primers mixtures (VH1,VH2,VH3) and JH (JHb,JHc),clonal IgH gene rearrangement was demonstated respectively in 34/33 of 44 B-NHL (positive rate 77%,75%). The total positive rate was 95% (42/44) by combined family-specific primers mixtures (VH1,VH2,VH3) of FR3A,FR2A,FR1 gene. Four of 15 T-NHL revealed clonal IgH gene rearrangement,while 5 LRH had no clonal IgH gene rearrangement. One NHL unclassified by immunohistochemical methods was classified definitely as B cell-derived lymphoma by PCR. Conclusion The detection rate of IgH gene rearrangement can be improved by combined usage of several pairs of primers,especially family-specific primers. Detecting clonal IgH gene rearrangement is significant in the procedure of differential diagnosis for B/T-NHL and reactive hyperplasia.

Abstract: Objective To analyze the application effect of rapid diagnostic techniques in Shaanxi from 2016 to 2020,and to provide basis for further optimizing the process of tuberculosis detection and formulating prevention and control strategies. Methods A total of 104 437 cases of tuberculosis patients registered in Shaanxi Province from 2016-2020 were exported from the Tuberculosis Information Management System (The subsystem of China Disease Prevention and Control
Information System) according to first management unit, and the laboratory test results of sputum smear, sputum culture and molecular tests were collected to statistically analyzed the positive rate of etiology, sputum smear, sputum culture, molecular
biology testing rate, and indicators of positive testing rate of tuberculosis patients. Results From 2016 to 2020, the etiology�positive rate of tuberculosis in Shaanxi province were 13.49% (2 664/19 754), 22.68% (5 081/22 401), 35.99% (8 232/22 876),
48.14% (10 438 / 21 682), 52.65% (9 332 / 17 724), respectively, with an increasing trend (χ2
trend=9 473.12, P<0.001) year by
year; the proportion of molecular tests positive only in etiology-positive pulmonary tuberculosis (PTB) were 0 (0/2 664), 0.16%
(8/5 081), 15.44% (1 271/8 232), 27.58% (2 879/10 438), 31.52% (2 941/9 332), respectively, with an increasing trend year by
year (χ2
trend=2 971.44, P<0.001); the molecular test rates of the 5 years were 0.01% (2 / 19 754), 0.38%(85 / 22 401), 21.11%
(4 828/22 876), 52.42%(11 365/21 682), 55.18%(9 780/17 724), respectively, with an increasing trend year by year (χ2
trend =
28 269.23, P<0.001). The rate of molecular test in sputum smear-negative was 22.72%(17 976 / 79 130). The proportion of
patients with only molecular test-positive was 33.43% (4 032/12 062) in municipal designated hospitals, and 11.99%(2 279/
19 014) in county-level designated hospitals, the difference was statistically significant (χ2
=2 096.46, P<0.001).
Conclusions The rate of molecular biology testing in Shaanxi Province from 2016 to 2020 showed a year-on-year increase.
Through the application of rapid molecular tests, the etiology-positive rates of tuberculosis have been increased significantly,but the current molecular test detection rate is not high compared with other provinces, especially in county-level designated
hospitals and smear-negative patients, so we should make a big promotion in application of rapid molecular technique.

To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.

OBJECTIVETo study the effect of acupuncture on the immune function of sepsis patients.
METHODSNinety sepsis patients were assigned to the control group, the thymosin a1 group, and the acupuncture treatment group according to random digit table, 30 patients in each group. Patients in the control group were treated according to the guideline of Surviving Sepsis Campaign (SSC). Patients in the control group received routine treatment. Those in the thymosin alpha1 group additionally received subdermal injection of thymosin alpha1 (1.6 mg), once per day for 6 successive days. Needling at related points such as Zusanli (ST36), Yanglingquan (GB34), Neiguan (PC6), Guanyuan (RN4), and so on, was performed in patients of the acupuncture treatment group, once per day for 6 successive days. T cell subgroups (CD3+, CD4+, CD8+, CD4+ /CD8+) and immunoglobulin levels (IgG, IgA, IgM) were detected. The length of ICU hospital stay, hospital readmission rate, and 28-day mortality were compared among the three groups.
RESULTSAfter six days of treatment, CD3+, CD4+, CD8+, IgG, IgA, IgM, and CD4+ /CD8+ ratio of three groups were all significantly increased (P < 0.01). Of them, CD3+, CD4+, CD8+, IgG, IgA, and IgM increased more significantly in the thymosin alpha1 group and the acupuncture treatment group (P < 0.01). Compared with the control group, the ICU hospitalization length was significantly shortened, the hospital readmission rate and the 28-day mortality were lower in the thymosin alpha1 group and the acupuncture treatment group (P < 0.05, P < 0.01). There was no statistical difference in each index between the thymosin alpha1 group and the acupuncture treatment group (P > 0.05).
CONCLUSIONAcupuncture could adjust the immune function of sepsis patients, improve their immunological indicators and prognoses.

To provide accurate information on geographic distribution of crude drug Sailonggu in the plateau, we identified zokor species (Eospalax spp.) in Qinghai-Tibet Plateau using molecular methods. Based on the mitochondrial cytochrome B (cytb) gene sequences, we then extracted haplotypes from these sequences and reconstructed phylogenetic trees for the haplotypes using both maximum likelihood (ML) and Bayesian inference (BI) methods. Based on the trees, the species of each sample were determined. Five hundred and three samples from 35 populations were sequenced and their whole cytb sequences (1140 bp) were obtained. From these sequences 150 haplotypes were detected, in which, 126 were Eospalax baileyi, 20 were E. cansus, and 4 were E. smithi of the 35 populations, 28 were E. baileyi type, 5 were E. cansus type, and the remaining 2 were mixed of E. baileyi + E. cansus (DT2) and E. baileyi + E. smithi (ZN3). The results showed that, the regions around the Qinghai lake and near the upper stream of Yellow River started at Guide could be viewed as the producing area of authentic Sailonggu, and also, the cytb gene is a powerful molecular marker to determine the species of zokors as well as for the authentication of geographic distribution of Sailonggu.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.
METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.
RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).
CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.
