OBJECTIVE: To explore the regularities of clinical application of hand acupuncture therapy to the treatment of diseases of different departments by using data mining technique, so as to provide a reference for clinical practice. METHODS: We searched papers, academic dissertations and case reports (published in journals from Jan 1, 1953 to December 31, 2017) from databases of China National Knowledge Internet (CNKI), VIP, and Wanfang, and also searched papers from medical books about hand acupuncture treatment of different diseases/illness by using keywords of "hand acupuncture" and "hand acupoints"， followed by constructing a database after sorting, screening, recording, extracting, and statistical analysis by using a computer. Then, the data mining was conducted for summarizing the characteristics and rules of the hand acupuncture therapy in clinical application. RESULTS: The hand acupuncture therapy in Chinese medical journals was found to be applied to various clinical departments, with the frequency from high to low successively being 16 types of diseases (37.21%) in the surgery, 15 diseases (34.88%) in the internal medicine, 2 diseases (4.65%) in the pediatrics, 8 diseases (18.60%) in the ophthalmology-otorhinolaryngology, 1 disease (2.33%) in the genecology and 1 disease (2.33%) in the dermatology. In the treatment of diseases, the cure plus markedly effective rate of hand acupuncture was found to be highest for diseases of the pediatrics (90.65%), and was 88.45% surgery, 78.06% internal medicine, 89.96% ophthalmology-otorhinolaryngology, 60.61% gynecology, and 67.73% dermatology, respectively. When hand acupuncture used, the acupoints of the hand region on both sides, healthy side and affected side were often selected, and movement exercise was often used in combination, particularly for problems of the surgery. In the collected medical records and 6 acupuncture books, the hand acupuncture was employed for treatment of 34 and 123 kinds of diseases or problems, respectively, with the tissue injury, lumbocrural pain being most frequently seen in the records, and abdominal pain, lumbocrural, chest obstruction, etc. most frequently seen in the acupuncture books. CONCLUSION: Hand acupuncture therapy is widely used in the treatment of many clinical problems of different departments, such as tissue injury, leg pain, etc. of the surgery; abdominal pain, asthma, etc. of the internal medicine; infantile enuresis, diarrhea, etc. of the pediatrics. Acupoints of the hand on the unilateral side are frequently employed and may have a better therapeutic effect.

Objective To screen the 5 EV71 vaccine candidates which were isolated from MRC-5 cells to find one as the vaccine virus. Methods The ICR mother mouse were immunized by intraperitoneal injection with the 5 vaccine candidates which were made from monoclonal EV71 virus. Two weeks after booster immunization, the animals were allowed to mate, another booster was given after 2 weeks, and then attracted the milk mouse within 24 h with different types of virus by cranial cavity injection. The survival condition were recorded everyday, and the antibody titre(IgG) were detected by ELISA, the virus titre of intestine were detected by nest-PCR, and neutralizing antibodies were determined using a microassay with MRC-5 cells, and then the data were analyzed by SPSS16.0. Results The antibody titre of 5 virus immunized ICR mouse were improved with the increase in the immune times, and they got difference in neutralization capacity, the survival rate after fatal attract and the virus titre of the intestine.

ObjectiveTo develop an ELISA method for quantitative determination of enterovirus 71 (EV71) antigen.The method can be applied to detect EV71 antigen contents and analyze the correlation between immunogenicity and immunoprotection.It also can be used for tissue culture infective dose( TCID50 ) assay.MethodsA double antibody sandwich ELISA method was developed for quantitative determination of EV71 antigen on the basis of the high-affinity neutralizing monoclonal antibodies ( K8G2 and Y8H2-HRP).This method was compared with microscopic observation for the detection of EV71 TCID50.The correlation was analyzed between the specific activity of EV71 antigen and the EV71 neutralizing antibody titer in immune serum.ResultsThe linear range of this method was 0.125-4.0 U/ml and the R2 value was 0.9911.The reagent did not react with other antigens except EV71 antigen.The recovery ratio of this method was 0.89-1.16.The coefficient of variation was less than 15％.The heat recovery rate was above 85％ when the reagent was in 37℃ for 9 days.There was a good correlation in TCID50 of EV71 between this method and microscopic observation,r=0.990.The specific activity of EV71 antigen had positive correlation with the neutralization titer of immune serum in 21 EV71 strains,r=0.930.ConclusionThe quantitative ELISA method for EV71 antigen was developed,which could be used to detect EV71 antigen contents and analyze TCID50.The specific activity of EV71 antigen detected by the method could be used to evaluate the immunoprotection of the vaccine potency test.

OBJECTIVETo observe the acute hemodynamic effects of intravenous diltiazem in patients with congenital heart defect (CHD) and severe pulmonary hypertension (HP) post cardiac surgery.

METHODSFrom November 2003 to September 2005, 12 patients with CHD and severe HP (4 male, mean age 17.8 +/- 9.8 years) after cardiac surgery received intravenous diltiazem (3 - 5 microg x kg(-1) x min(-1)) in the Intensive Care Unit. Mean pulmonary artery pressure (mPAP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), systemic vascular resistance (SVR), pulmonary vascular resistance (PVR) were monitored with Swan-Ganz catheter before (T1) and 6 hours (T2) after diltiazem injection, before weaning patients off of ventilator (T3), 1 hour (T4) and 24 hour (T5) after extubation.

RESULTSAll patients survived during the observation period and no patient developed pulmonary hypertension crisis. The average ventilation time was (88.7 +/- 50.1) hours. Mean ICU stay time was (5.8 +/- 3.1) days. Compared to T1, mPAP was significantly decreased at T3 and T5, MAP significantly increased at T4 and T5, HR significantly reduced at T2 and thereafter, SV significantly increased at T3, T4 and T5 and PVR significantly increased at T3 and T5 while SVR remained unchanged after diltiazem therapy.

CONCLUSIONIntravenous use of diltiazem is safe and effective for patients with CHD with severe HP post cardiac surgery.

OBJECTIVETo establish and evaluate a rat model of type 2 diabetes mellitus (T2DM) associated with depression for further elaborating the disease.

METHODSTwenty-four Wistar rats were randomly divided into three groups: normal group (group N), T2DM group (group T) and T2DM with depression group (group T + D), with 8 rats in each group. The T2DM rat model was induced by high fat diet and low dose of Streptozotocin (STZ) injection, and in addition, the T2DM rats were made restraint stress for 21 days. After the model was established, the insulin tolerance test (ITT) and oral glucose tolerance test (OGTT) were performed. Then the rat depression level was analyzed by open field test, and the concentration of 5-hydroxytryptamine (5-HT) and dopamine (DA)was determined by ELISA to confirm the model identity.

RESULTSThe blood glucose level in group T and group T + D didn't return to the normal level at 180 minutes in the ITT and OGTT test; Compared with the group N, the max movement distance, retaining time in the central zone and the retaining frequency within 5 minutes in the group T + D decreased; 5-HT and DA level in the serum of rats in. group T + D was reduced.

CONCLUSIONA rat model of type 2 diabetes mellitus associated with depression has been successfully established by high fat diet and injection of low dose streptozotocin in combination with restraint stress for 21 days. This rat model is useful for further relevant studies.

Objective To investigate the characteristics of maternal thyroid function of pregnant women with negative thyroid antibody in high water iodine area. Methods The investigation sites were selected,which were the Hospital for Women and Children of Jinghai county in the high water iodine area(drinking iodine > 200 μg/L) and the Hospital for Women and Children of Heping district in Tianjin in the adaptive iodine area (drinking iodine < 10μg/L,popularization rate of iodized salt > 90％,residents urinary iodine > 200μg/L). In the maternal and child hospitals,50 pregnant women of each stage from obstetric clinics in first,second,third term of pregnancy were selected,the blood samples were collected and the thyroid function were measured with chemiluminescence. Water,salt and diurnal optional urine samples were measured for iodine concentration. Iodine levels of urine,water,salt were determined respectively by As-Ce catalysis spoctrophotometry method,quantitative determining kit which use time-recorded determination by catalytic effect on the As-Ce reaction and sodium hyposulfite titration method. Results ①In pregnant women with negative thyroid antibody,serum TT_4,TT_3,FT_4 in first term of pregnaney and TT_4,TT_3 in second term of pregnancy were significantly lower in high water iodine area than low water iodine area(111.97 nmol/L vs 140.46 nmoL/L,Z = 3.56,P < 0.01 ; 1.86 nmol/L vs 2.26 nmol/L,Z = 2.35, P < 0.05; 14.13 pmol/L vs 16.32 pmol/L,Z = 5.14,P < 0.01,and 11.98 pmol/L vs 14.30 pmol/L,Z = 5.75,P < 0.01 ; 4.04 pmol/L vs 4.32 pmol/L,Z = 2.76,P < 0.01),while TT_3 and TSH in third term of pregnancy were significantly higher(2.88 nmoL/L vs 2.70 nmol/L,Z=-2.27,P< 0.05; 2.37 mU/L vs 1.75 mU/L,Z =-2.70, P < 0.01).②Concentration of water iodine and urine iodine were higher(205.57μg/L vs 8.26 μg/L,Z =-14.71,P < 0.01 ; 305.91 g/L vs 191.86 g/L,Z =-5.30,P < 0.01),while salt iodine was lower(26.5 mg/kg vs 31.7 mg/kg,Z =-5.86,P < 0.01) in high water iodine area. ③Among 290 selected healthy pregnant women without medical history of thyroid diseases,there was no significant difference in positive rate of thyroid antibody in each term of pregnancy between high water iodine area and low water iodine area(10.20％ vs 10.64％ ; 14％ vs 9.52％ ; 4％ vs 7.69％ ; all P > 0.05). Conclusions The thyroid function of pregnant women with negative thyroid antibody in high water iodine area is different from pregnant women in low water iodine area with universal salt iodization. Enhanced monitoring on thyroid function of pregnant women in high water iodine area should be performed,especially in first and second trimester.

OBJECTIVETo review the origin, diagnosis, treatment and public health concern of New Delhi metallo-β-lactamase (NDM)-producing bacteria.

DATA SOURCESWe searched database for studies published in English. The database of PubMed from 2007 to 2015 was used to conduct a search using the keyword term "NDM and Acinetobacter or Enterobacteriaceae or Pseudomonas aeruginosa."

STUDY SELECTIONWe collected data including the relevant articles on international transmission, testing methods and treatment strategies of NDM-positive bacteria. Worldwide NDM cases were reviewed based on 22 case reports.

RESULTSThe first documented case of infection caused by bacteria producing NDM-1 occurred in India, in 2008. Since then, 13 blaNDM variants have been reported. The rise of NDM is not only due to its high rate of genetic transfer among unrelated bacterial species, but also to human factors such as travel, sanitation and food production and preparation. With limited treatment options, scientists try to improve available therapies and create new ones.

CONCLUSIONSIn order to slow down the spread of these NDM-positive bacteria, a series of measures must be implemented. The creation and transmission of blaNDM are potentially global health issues, which are not issues for one country or one medical community, but for global priorities in general and for individual wound care practitioners specifically.

Objective: To observe the changes of PD-1 expression, mRNA level and cytotoxic activity of CD19 CAR-T cells during the culture process of CAR-T cells. Methods: The peripheral blood T cells of 6 lymphoma patients with high expression of PD-1 and 6 healthy volunteers were the source of CAR-T cells. The expression of PD-1 was analyzed by flow cytometry. The mRNA level of PD-1 was analyzed by PCR. The cell proliferation was analyzed by CCK-8 assay. The cytotoxicity was analyzed by LDH assay. Results: ①The transfection efficiency of high PD-1 expression T cells and healthy volunteer T cells were as the same (P>0.05) . ②The cell proliferation capacity of CD19 CAR-T cells from high PD-1 expression T cells or healthy volunteer T cells, with or without PD-1 inhibitor were as the same (P>0.05) . ③The cytotoxicity to lymphoma cells of high PD-1 expression T cells and CAR-T cells were lower than that of these two T cells combined with PD-1 inhibitor and the CAR-T cells from healthy volunteer T cells (P<0.001) . There was no difference of the cytotoxicity between the CAR-T cells from high PD-1 expression T cells combined with PD-1 inhibitor and the CAR-T cells from healthy volunteer (P>0.05) . ④There was no difference of the expression of PD-1 in all CAR-T cell groups during the culture process (P>0.05) . There was no difference of mRNA level of PD-1 in all groups during the culture process (P>0.05) . ⑤The PD-1 expression of CAR-T cells increased by the time of culture after contacting with lymphoma cells (P<0.001) . The PD-1 inhibitors could antagonize this effect. There was no difference of mRNA level of PD-1 in all groups after contacting with lymphoma cells (P>0.05) . Conclusion: The PD-1 expression of CAR-T cells from high PD-1 expression T cells increased by the time of culture after contacting with lymphoma cells. However, the mRNA level of PD-1 of all groups did not change, even if PD-1 inhibitor was applied.
