This paper arranged the research results of the chemi-cal components and pharmacological effects of five kinds of Loni-cera. All these herbs have organic acids( chlorogenic acid) , fla-vonoids( galuteolin) , triterpenoid saponins, iridoids and volatile oils, and have antibacterial, antiviral, anti-inflammatory, an-tioxidant, hepatoprotective, immunological effects, and so on.The major medicinal ingredients and pharmacological effects of these herbs have no significant difference. Some similar pharma-cological effects are caused by different chemical components.

To investigate the impact of maternal hepatitis B virus (HBV) carrier state on twin pregnancy outcomes. Methods From January 2004 to December 2012, 569 women with twin pregnancy were hospitalized in Nanjing Drum Tower Hospital. Thirty-two women positive for hepatitis B surface antigen (HBsAg)(negative for hepatitis B e antigen, with normal liver function before conception)were included in the HBsAg-positive group and the other 537 women were included in the HBsAg-negative group. The pregnancy outcomes of the two groups were compared by t test and Chi-square test. The risk factors for neonatal birth weight were analyzed by multivariate regression analysis. Results Compared with the HBsAg-negative group, the HBsAg-positive women had a higher incidence of abnormal liver function (alanine aminotransferase≥50 U/L) [18.8% (6/32) vs 5.8% (31/537), χ2=6.367, P=0.012]. The incidence of gestational diabetes mellitus was 21.9% (7/32) in the HBsAg-positive group, which was higher than in the HBsAg-negative group [11.6% (62/537)], although the difference was not significant (χ2=2.132, P=0.144). The incidences of intrahepatic cholestasis of pregnancy,hypertensive disorders complicating pregnancy, premature rupture of membranes, placenta previa, fetal distress, postpartum hemorrhage, preterm birth, caesarean section, umbilical cord around the neck, meconium-staining amniotic fluid and neonatal asphyxia were no statistical difference between two groups (all P<0.05, respectively). Multivariate regression analysis showed that gestational diabetes mellitus (β=67.869, 95%CI: 0.494-135.244, P=0.048), maternal age (β=6.592, 95%CI: 2.020-11.880, P=0.006) and gestational age (β=164.069, 95%CI:154.426-173.712, P<0.01) were risk factors for neonatal birth weight, but not the maternal HBsAg-positive status (β=78.864, 95%CI: -16.950-174.678, P=0.107). Conclusion Twin pregnancy and HBV carrier state increase the risk of abnormal liver function, but not other adverse pregnancy outcomes and newborn diseases.

ObjectiveTo explore the effect of the calcium phosphate cement (CPC) /calcium polyphosphate fiber (CPPF) composites mixed with different proportion of minimal morselized bone on repair of bone defect in vivo. MethodsA total of 36 New Zealand white rabbits were completely randomly designed into A, B, C, D groups and their bilateral radial bone defect model was prepared. The minimal morselized bone (300-500 μm in diameter) was made from the iliac of those rats. The CPPF and CPC were evenly mixed into CPC/CPPF composites which were divided into four groups in accordance with the CPPF weight O, 10％, 30％ and 50％ in CPC/CPPF composite. The CPC/CPPF composites of the four groups was mixed with the minimal morselized bone with ratio of 6:4 and then the mixture was implanted the bone defect of the rabbits in four groups. The gross, X-ray and histological observations were done at four and eight weeks. The biomechanical test was performed at eight weeks. Results When CPPF occupies 30％ of the CPC/CPPF composite, the maximum compressive load and bending loads were better than those in the other groups ( P ＜ 0.05 ), when the histological observation showed the most tight link between the artificial composite and the bone interface and the closest similarity between material degradation rate and the ossification rate, with the best osteogenesis and the optimal ratio.ConclusionThe repair of bone defect can attain the optimal outcome through adding a certain ratio of minimal morselized bone into the CPC/CPPF to adjust the degradation rate of composites.

Objectives To evaluate the long-term outcomes of childhood low-or intermediate-risk neuroblastoma (NB) and their relevant prognostic factors. Methods A total of 70 new cases of low-or intermediate-risk NB diagnosed and treated by NB-99 protocol between 1999 and 2008 were analyzed retrospectively. Results Of these 70 NB patients, fourteen patients were in low-risk group and 56 were in intermediate-risk group. Sixty-seven patients reached complete remission (CR) or very good partial remission and 3 (5%) achieved partial remission. Ten patients relapsed. One patient occured second malignant neo-plasm. No patients died of chemotherapy-related adverse events or infections. The 5 year overall survival rate was 85.9%, event-free survival rate was 81.0%. Bone marrow infiltration, age at diagnosis, stage, lactate dehydrogenase level had a significant effect on prognosis. Conclusion Develop cytogenetic and molecular biology tests and pretreatment risk stratification are im-portant for further improvement of treatment protocol.

Objectives To evaluate the clinical features, treatment scheme and long-term outcomes of stage 1、2 childhood neuroblastoma (NB). Methods The retrospective study included 49 newly diagnosed NB stage 1、2 patients from June 1998 to December 2010. Clinical data and long-term outcomes were analyzed. Results Twenty-four patients with stage 1 NB and twenty patients with stage 2 NB were found among all 237 patients with NB enrolled in this study. The median age at diagnosis was 25 months( 2 week to 9 year old),29 males and 20 females. Thirty-one patients (63.6%) without symptoms were discovered with tumor by physical or imaging examination. Thorax and abdomen were the most common sites of primary tumor (21 and 22 cases, accounting for 42.9% and 44.9% of all patients, respectively). Forty (81.6%) NB patients had favorable pathology classification. One patient was of MYCN amplification status. Urine vanilla mandelic acid was normal in 32 (91.4%) patients, and serum lactate dehydrogenase was less than five times of the normal value in all patients. Ten NB patients were treated ac-cording to the low-risk protocol who received surgery alone.Thirty-nine patients were treated according to intermediate-risk protocol who received both surgery and chemotherapy. All the patients achieved very good partial remission (100%).The medi-an follow-up period was 60 months(22 months to148months). Nine patients were lost after a follow up of 3 months in medi-an. The 2-、3-、5-year event free survival and overall survial of all 49 patients was 100%. Conclusions The prognosis for neu-roblastoma of stage 1、2 in this study was with 100%survival, which provides opportunity for further reduction of dosage and/or duration of episodes in chemotherapy.

OBJECTIVE: To compare the effect of rehabilitation of prelingual deaf children who used a cochlear implant (CI) in one ear and a hearing aids in the opposite ear while the hearing level of the opposite ears are different. Hearing ability, language ability and learning ability was included in the content. The aim of this research is to investigate better style of rehabilitation, and to offer the best help to the prelingual deaf children. METHOD: Accord ing to the hearing level of the ear opposite to the one wearing a cochlear implant and whether the opposite ear wear a hearing aid or not, 30 prelingual deaf children were divided into three groups, including cochlear implant with opposite severe hearing loss and hearing aid ear (CI+SHA), cochlear implant with opposite profound hearing loss and hearing aid ear (CI+PHA), cochlear implant only (CI). The effect of rehabilitation was assessed in six different times (3,6,9,12,15 and 18 months after the cochlear implants and hearing aids began to work). RESULT: The longer time the rehabilitation spends, the better the hearing ability,language ability and the learning ability were. The hearing ability of CI+SHA was better than those of CI+PHA (P<0.05) and CI (P<0.05). The language ability and learning ability of CI-SHA was nearly equal to those of the other two groups. CONCLUSION The prelingual deaf children should take much more time on rehabilitation. The effect of rehabilitation for prelingual deaf children who used cochlear implant in one ear and hearing aid in the other depend on the residual hearing level of the other ear. If a prelingual deaf children still has any residual hearing level in the ear opposite to the cochlear implant ear, it is better for him/her to wear a hearing aid in the ear.

Objective To test the differences in diffusion properties?namely fractional anisotropy (FA) and apparent diffusion coefficient(ADC)?between amateur marathon runners and healthy volunteers′thigh muscles using diffusion tensor imaging (DTI) at rest. Methods Thirty amateur marathon runners(Group A) and 20 healthy volunteers (Group B) were recruited. All were males and their age was between 28 to 53 years. All subjects underwent both thigh DTI examination. DTI parameters FA and ADC were evaluated in thigh muscles(rectus femoris, vastus lateralis, vastus intermedius, vastus medialis, adductor longus, adductor magnus, biceps femoris long head, semitendinosus and semimembranosus)in all subjects. We tested the differences in diffusion properties between GroupA and B using independent sample t test. Results The average FA value of the thigh muscles measured in Group A was (0.24 ± 0.03), which was significantly lower than that in Group B=(0.27±0.03)(t=5.164,P<0.01). The average ADC value of the thigh muscles measured in Group A was (1.74±0.10)×10?3mm2/s, which was significantly higher than that in Group B=(1.70±0.09)×10?3mm2/s (t=2.060,P<0.05). The FA value of Group A was lower than that of Group B in the rectus femoris, vastus lateralis, vastus medialis, biceps femoris long head, semitendinosus and semimembranosus (P<0.05). The ADC value of Group A was higher than that of Group B in the vastus intermedius, vastus medialis and biceps femoris long head(P<0.05). Conclusions In the absence of positive findings from conventional MRI, DTI technique can non?invasively assess the subtle changes in the bilateral thigh muscles of amateur marathon runners at rest in the early stage of microscopic molecular level, providing important imaging evidence for early changes in skeletal muscle caused by marathon.

Objective To investigate the effects of light acute hypervolemic hemodilution on early postop-erative cognitive function in elderly patients. Methods A total of 60 patients treated by radical surgery were equally randomized to an AHH and a non-AHH control group.Using the Mini-Mental State Examination scale (MMSE),we evaluated the cognitive function of the patients.We made comparisons between the two groups in the plasma S100β levels at T0(before anesthesia induction),T1(immediately after hemodilution),T2(immediately after operating),T(36 hour after operating)and T(424 hour after operating).Results The S-100β lever at T2、T3 and T4were markedly higher than T0in both groups(P<0.05);At T3and T4,the S-100β lever was higher in non-AHH control group than AHH group(P<0.05).There was no significant difference in the incidence of postopera-tive cognitive dysfunction between the two groups(P>0.05)There was no significant difference in the incidence of postoperative cognitive dysfunction between the two groups(P > 0.05). Conclusions AHH can significantly reduce plasma S100β in elderly patients,but there is no effect on early postoperative cognitive function.

Objective To investigate whether the median(50%)effective effect-concentration(EC50)of propofol inducing loss of consciousness (LOC) varies. Methods 56 patients undergoing gastroscopy under general anaesthesia were enrolled on the study. Anaesthesia was conducted with a target-controlled infusion(TCI) of propofol. The initial target effect-site propofol concentration (Ceprop) was 5.00 μg/mL and was adjusted stepwise by 0.50μg/mL by an up-down sequential method to reach no-movement. Results Propofol EC50 to induce no-movement was higher in patients with anxiety than those without anxiety(6.46μg/mL vs. 5.75μg/mL,P<0.05). Conclusions During general anaesthesia ,patients with anxiety had a higher propofol EC50 for no-movement compared with those without anxiety. Differences in preoperative anxiety levels may reduce anaesthetic effects.

Objective To evaluate the long-term efficacy of neonatal immunoprophylaxis in children born from mothers infected with hepatitis B virus (HBV),and to clarify whether a booster vaccination is required.Methods Totally 252 children of HBV infected mothers,who were negative for hepatitis B surface antigen (HBsAg) tested in Nanjing Drum Tower Hospital in 2012,were enrolled to participate in this study from July to September,2017.Revaccination of hepatitis B vaccine was recorded and other relevant informations were collected.HBV serologic markers were detected in each child.Results Totally 198 children (78.6％) were followed up.They were (8.4 ± 2.2) years old and 112 cases were boys.All 198 children were negative for both HBsAg and hepatitis B core antibody (anti-HBc).The overall positive rate of hepatitis B surface antibody (anti-HBs) (≥ 10 IU/L) was 65.7％.During period of 2012 to 2017,53 children were boosted with hepatitis B vaccine.Their median anti-HBs titer in 2017 was higher than that in 2012 (327.95 IU/L vs.158.01 IU/L),and the difference was significant (Z =-4.480,P ＜0.05).The other 145 children were not revaccinated,their median anti-HBs titer was decreased from 214.19 IU/L in 2012 to 70.49 IU/L in 2017,and the difference was significant (Z =-6.575,P ＜ 0.05).Of 145 children who were not revaccinated,25 cases had anti-HBs levels ＜ 10 IU/L and 120 cases ≥ 10 IU/L in 2012,and the other 47 cases also showed the antibody ＜ 10 IU/L in 2017,but none of them was infected with HBV.Conclusions Neonatal immunoprophylaxis in infants from HBV-infected can provide long-term protection against hepatitis B.The children with anti-HBs ＜ 10 IU/L are still immune to HBV and booster vaccination for them seems unnecessary.
