This paper reviews the researches on acupuncture preconditioning before surgery in recent years and explores its application value from three aspects, i.e. relieving preoperative anxiety, preventing from postoperative cognitive dysfunction, and preventing from postoperative gastrointestinal dysfunction. As a relatively safe non-drug treatment, acupuncture has the underlying advantages in participating into multidisciplinary coordination in the enhanced recovery after surgery (ERAS). By building up higher-quality medical evidences and revealing the effect mechanism of acupuncture from multi-dimenisonal aspects, it is expected that acupuncture technology can be coordinated with ERAS to optimize the clinical path in the perioperative period, and boost the development of the perioperative medicine ultimately.

This paper explored the chemical constituents of Boswellia carterii by column chromatography on silica gel, Sephadex LH-20, ODS column chromatography, and semi-preparative HPLC. The structures of the compounds were identified by physicochemical properties and spectroscopic data such as infrared radiation(IR), ultra violet(UV), mass spectrometry(MS), and nuclear magnetic resonance(NMR). Seven diterpenoids were isolated and purified from n-hexane of B. carterii. The isolates were identified as(1S,3E,7E,11R,12R)-11-hydroxy-1-isopropyl-4,8,12-trimethyl-15-oxabicyclo[10.2.1]pentadeca-3,7-dien-5-one(1),(1R,3S,4R,7E,11E)-4,8,12,15,15-pentamethyl-14-oxabicyclo[11.2.1]hexadeca-7,11-dien-4-ol(2), incensole(3),(-)-(R)-nephthenol(4), euphraticanoid F(5), dilospirane B(6), and dictyotin C(7). Among them, compounds 1 and 2 were new and their absolute configurations were determined by comparison of the calculated and experimental electronic circular dichroisms(ECDs). Compounds 6 and 7 were obtained from B. carterii for the first time.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective:To explore whether CD5 + CD19 + B cells has the function of secreteing interleukin-10 (IL-10) in vitro, and to further investigate its possible effects and mechanisms on CD8 + cells in the process of hepatitis B virus (HBV) infection. Methods:From July 2017 to June 2018, at Wuxi Second People′s Hospital Affiliated to Nanjing Medical University, 23 patients with chronic hepatitis B (chronic hepatitis B group), 18 patients with liver cirrhosis (liver cirrhosis group) and 19 healthy individuals in the same period as healthy controls (healthy control group) were enrolled. Peripheral blood mononuclear cell (PBMC) were isolated and cultured. CD5 + CD19 + B cells were isolated. The cells were analyzed by flow cytometry. The ratio of high CD5 + CD19 + B cells content (>6 % of lymphocytes), the secretion of IL-10 by CD5 + CD19 + B and the ratio of high IL-10 + cells content (>4 % of lymphocytes) of three groups were compared. The effects and possible mechanisms of CD5 + CD19 + B cells on the secreting of interferon-γ (IFN-γ) by CD8 + cells were analyzed. Liver biopsy and immunohistochemistry examination were conducted in 18 patients (13 patients with chronic hepatitis B and 5 patients with liver cirrhosis) and the expression of CD5 + CD19 + B cells in human liver tissues was analyzed. Chi square test and Fisher exact probability test were used for statistical analysis. Results:The ratio of high CD5 + CD19 + B cells content of liver cirrhosis group was higher than that of healthy control group (8/18 vs. 2/19) and the difference was statistically significant (Fisher exact probability test, P=0.029). The precentage of CD5 + CD19 + B cells in healthy control group ( n=10), chronic hepatitis B group ( n=23) and liver cirrhosis group ( n=18) accounted for 81.6%, 82.3% and 70.1%of IL-10 + cells, respectively, and the number of patients with high IL-10 + cells precentage was 2, 7 and 2, respectively. There were no statistically significant differences among three groups (all P>0.05). After stimulated with lipopolysaccharide and cultured for 48 hours, the precentage of CD8 + IFN-γ + cells in lymphocytes of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10) were compared, and the differences were not statistically significant (all P>0.05). After CD5 + CD19 + B cells were eliminated, the precentage of CD8 + IFN-γ + cells in lymphocytes increased in 5, 4 and 4 patients of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10). After adding IL-10 receptor blocker, the precentage of CD8 + IFN-γ + cells in lymphocytes in PBMC increased compared with that before the addition of IL-10 receptor blocker (7.23% vs. 6.87%). The results of immunohistochemistry examination of liver biopsy indicated that CD4 + and CD8 + cells were strong expressed in portal area of liver tissue of patients, while CD5 + and CD19 + were less expressed. Conclusions:CD5 + CD19 + B cells do not show obvious quantitative and functional differences in the process of chronic HBV infection, however the ability of CD8 + cells to secrete IFN-γ, which may be achieved by secreting IL-10 rather than by direct contact between cells.

Objective: To investigate the strong expression (S+) of P53 and BCL2 proteins in MYC/BCL2 double-expression DLBCL (DEL) and whether they can be used for the prognostic evaluation and stratified diagnosis of DELs. Methods: Tissue microarray were made by filed FFPE blocks of 174 DLBCL cases. The translocation of MYC, BCL2 and BCL6 genes were detected by FISH, and the proteins were detected by IHC. Data of clinicopathologic features and follow up of patients were collected and OS (overall survival) and PFS (progression free survival) were analyzed by statistics. Results: Eight double-hit lymphomas (DHLs) were identified in all cases, and 45 DELs were selected from 166 remaining cases, which have no significant difference in OS and PFS compared with non-DEL cases (P=0.668 and P=0.790) . Of 42 DEL-cases with follow up data, 24 cases with P53+ or/and BCL2 (S+) are significantly shorter OS and PFS than others (P=0.003 and P=0.000) , in which the cases with P53+/BCL2 (S+) co-expression were the worst prognosis, and P53/BCL2 co-weaker positive DEL cases even have superior OS and PFS than those non-DELs. Although statistics showed that the cases of P53+ or/and BCL2 (S+) have a lower OS and PFS in total cases (P=0.063 and P=0.024) , it is not the case when the DEL-cases take out from total cases, that is the cases with P53+ or/and BCL2 (S+) are as similar OS and PFS as others in non-DEL group (P=0.590 and P=0.550) . Conclusion: The strong expression of P53 and BCL2 proteins can be used as indicators of stratified diagnosis and poor prognosis of DEL.

Objective To investigate the degrees of injury severity of sepsis models made by different kinds of Escherichia coli. Methods The 152 mice were randomly divided into control group, DH5α group, 44102 group, and 25922 group, with 38 rats in each group. DH5α group, 44102 group and 25922 group were intraperitoneally injected with 300 μL of Escherichia coli DH5α, 44102 and 25922 at the concentration of 1.0 × 109CFU/kg to prepare sepsis models of different kinds of Escherichia coli. Control group was injected intraperitoneally with the same amount of normal saline. (1) After 8 h, four mice were taken from each group for peripheral blood bacterial culture . (2) After 12 h, ten mice in each group were used for measuring serum levels of TNF-α and IL-6 by enzyme-linked immunosorbent assay (ELISA). (3) Western blot assay was used to determine the serum levels of high-mobility group protein (HMGB1) in four mice of each group. (4) Ten mice in each group were used to measure serum levels of alanine transaminase (ALT), aspartate aminotransferase (AST), creatinine (CR) and blood urea nitrogen (BUN) by automatic biochemical analyzer. (5) After liver, lung and kidney tissues were fixed with formaldehyde, hematoxylin-eosin (HE) staining was performed (n=10 for each group). Results In DH5α group, 44102 group and 25922 group, bacteria, inflammatory cytokines TNF-α, IL-6 and HMGB1 protein, liver and kidney indicators ALT, AST, CR and BUN showed a sequential increasing trend (P＜0.01). The severe degrees of alveolar structure damage, hepatic cell infiltration and renal glomerular atrophy were DH5α group, 44102 group and 25922 group in turn. There were no obvious damages of lung, liver or kidney tissues in control group. Conclusion Escherichia coli 25922 induces severe sepsis injury and can be used to study the animal models of the initial inflammatory phase of sepsis. Escherichia coli 44102 induces moderate damage of sepsis and can be used in animal models that do not require definitive sepsis staging experiments. Escherichia coli DH5α induces less damage of sepsis and can be used to explore immunosuppressive therapy of the animal model of sepsis.

Objective To discuss the sleep quality of hospitalized patients with rheumatic diseases and the factors affecting the quality of sleep. Methods With Pittsburgh sleep quality index ( PSQI) questionnaire and the self-designed questionnaire about the factors affecting sleep were used to survey 125 patients with rheumatic disease from November 2013 to October 2014 in a level three class A hospital in Beijing city. Results Rheumatoid disease inpatients PSQI scores between 7 to 12 points had 35 cases, accounted for 28. 0%, more than 12 points having 6 cases, accounted for 4. 8%, PSQI various dimensions of 93 patients with seven hours of sleep time and accounted for 74. 4%, sleep efficiency more than 85% having 115 patients and accounted for 92. 0%, but the poor quality of sleep group with 113 cases and accounted for 90. 4%, sleep time group 101 cases of patients and accounted for 80. 8%, patients with sleep disorders in 120 cases, accounted for 96%, 111 cases of patients with daytime dysfunction, accounted for 88. 8%, and used hypnotic drugs in patients with only 13 cases, accounted for 10. 4%, group of patients with rheumatic disease of the Pittsburgh sleep quality index was higher than normal group (P<0. 01); there was no significant difference in the total score of PSQI and in patients with glucocorticoid (P <0. 05). The percentage of poor sleep quality was in patients with more than sixty years old, not continue to work or study and poor sleep before hospitalization, and sleep quality of patients affected by physical discomfort (P<0. 01);the primary factors affected patients′sleep was psychological factors. Conclusions The hospitalized patients with rheumatoid disease sleep quality are poor, while psychological factors are the main factors affecting sleep and corticosteroids is not absolutely the influencing factors of sleep. The elderly, the length of sleep before good quality patients should attract the attention of nurses. Using your own sleep drugs can improve sleep quality. Evaluation and assessment of patients′sleep quality can find out potential problems.

OBJECTIVETo analyze the measles immunity level of persistent population in Beijing.

METHODSA total of 2125 objects from 10 age groups, who had been living in Beijing for over 6 months, were selected from urban and rural areas in Beijing in 2012. Demographic characteristics, history of measles and vaccine immunization were investigated by questionnaire. 5 ml blood sample of each subject was collected, and the Measles IgG antibody was measured by ELISA assay.

RESULTSPositive rate of measles antibody was 84.71% (1800/2125) and standardized positive rate was 88.07% . Median of antibody was 960.46 IU/L. Positive rate and median of measles antibody were significantly different between population from different age groups (χ(2) = 341.60, P < 0.01; H = 216.27, P < 0.01). Antibody positive rate and median were lowest in the <1 year age group, which were separately 43.06% (90/209) and 185.80 IU/L; and highest in the 1-4 (97.31% (181/186) and 2448.81 IU/L) and 5-9 years age group (96.46% (218/226) and 1910.72 IU/L). The range of antibody positive rate and median in adults of ≥ 15 years were 81.98%-90.14% and 744.38-1474.84 IU/L. Antibody positive rate and median in persistent population, which were separately 82.45% (883/1071) and 899.82 IU/L, were lower than those in migrant population, which were 87.00% (917/1054) and 166.19 IU/L, respectively (χ(2) = 8.51, P < 0.01;U = 538 704.00, P < 0.01). Antibody positive rate and median in population with vaccination history, which were separately 91.95% (891/969) and 1443.11 IU/L, were higher than those population without vaccination history and people whose history unknown (32.95% (57/173) , 127.33 IU/L; 86.67% (852/983) , 923.73 IU/L). The difference showed statistical significance (χ(2) = 399.92, P < 0.01; H = 202.11, P < 0.01).

CONCLUSIONAmong the persistent population in China, measles antibody level among the children aging 1-9 years old was high enough to prevent outbreak and epidemic of measles. However, we should try our best to strengthen the measles antibody level among the babies younger than 1 year old and the migrant population aging between 15 and 40 years old.
