Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.

METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.

RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.

CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.

Objective To study the mechanism of marcosomia by investigating insulin-like growth factor 2(IGF_2)imprinting status,expression level and the promoter usage in the placenta of macrosomia. Methods We selected heterozygous cases for Apa Ⅰ polymorphism in exon 9 of IGF_2 gene and then analyzed its imprinting status in 168 placentas of macrosomia and normal pregnancies.IGF_2 transcription levels and promoter usages in macrosomic and normal placenta were evaluated by using semi-quantitative RT- PCR assay.Results Thirty specimens of macrosomic placenta and 30 of normal placenta were identified as heterozygous for IGF_2.All of the heterozygous specimens showed maintenance of imprinting.The expression of placental IGF_2 mRNA(2.2?1.2)was significantly higher in macrosomia than that of normal weight group (1.6?0.6,P 0.05).Conclusion It is possible that over expression of IGF_2 in placenta contributes to macrosomia while the promoter usage and imprinting status are not associated with macrosomia.

This study was purposed to investigate the correlation of absolute lymphocyte count (ALC) in peripheral blood of de novo multiple myeloma (MM) patients with clinical characteristics, therapeutic efficacy and prognosis. The clinical data of 34 de novo patients with MM in our hospital from January 2002 to August 2011 were analysed retrospectively. According to ALC, patients were divided into ALC < 1.3×10(9)/L (n = 15) group and ALC ≥ 1.3×10(9)/L (n = 19) group. The correlation of incipient ALC levels of de novo MM patients with clinical data such as sex, age, type of MM, bone destruction, clinical staging and grouping, levels of LDH, β(2)-MG, creatinine and albumin, as well as therapeutic efficacy was analysed. The results showed that ALC was (0.4 - 2.9)×10(9)/L (median ALC was 1.3×10(9)/L) in untreated patients. The effective rate of therapy was 20% in ALC < 1.3×10(9)/L group while it was 57.9% in ALC ≥ 1.3×10(9)/L group. There was statistical difference in effective rate between two groups (χ(2) = 4.9696, P < 0.05). Compared with the ALC ≥ 1.3×10(9)/L group, the percentage of the CD4 and CD4/CD8 ratio were reduced and the percentage of the CD8 increased (P < 0.05). But no significant differences were found in sex, age, type of MM, bone destruction, clinical staging and grouping, levels of LDH, β(2)-MG, creatinine and albumin in those patients (P > 0.05). It is concluded that ALC in de novo patients with MM may be used as the important indication for analysing therapy effect and prognosis.

OBJECTIVETo investigate and evaluate the clinical therapeutic effect of low-dose interleukin-11 treatment of thrombocytopenia in patients with malignant hematologic diseases after chemotherapy.

METHODS70 patients with hematologic malignancies including acute leukemia, lymphoma and multiple myeloma were randomly divided into treatment group (35 cases) and control group (35 cases) and were treated with chemotherapy. Cases in the treatment group received subcutaneous injection of interleukin-11 (50 µg × kg(-1) × d(-1)) until platelet counting recovered ≥ 50 × 10(9)/L, while cases in the control group were not administrated with interleukin-11.

RESULTSThe mean time of platelet recovery in the treatment group was 9.6 days, significantly shorter than that (14.0 days) in the control group (P < 0.05). The minimum platelet counting in the treatment group was significantly higher than that in the control group (16.2 × 10(9)/L vs. 11.6 × 10(9)/L, P < 0.05). The mean times of platelet infusion after chemotherapy in the treatment group and control group were 2.88 and 2.98, respectively (P > 0.05).

CONCLUSIONAdministration of interleukin-11 in thrombocytopenic patients with hematologic malignancies after chemotherapy may not only remarkably enhance platelet counts and shorten the recovery time of thrombocytopenia, but also has only mild side effects.

Objective To compare the efficacy and safety of different courses of caffeine citrate injection in the treatment of very low birth weight infants.Methods Very low birth weight infants were divided into long course group and routine course according to cohort method.2 groups of children were given intravenous infusion of caffeine citrate injection loading dose(20 mg·kg-1)within 3 days after birth,and the dose was maintained at 5 mg·kg-1 after 24 hours(qd).In the long course group,caffeine citrate injection was used to correct gestational age＞34 weeks,and in the routine course,caffeine citrate injection was used to correct gestational age 33-34 weeks.The use of caffeine citrate injection,clinical efficacy,neonatal behavioral neurological scale(NBNA)score and the occurrence of adverse drug reactions were compared between the two groups.Results 116 cases were included in this study,64 cases in the long course group and 52 cases in the routine course.After treatment,the total clinical effective rate of the long course group and the routine course was 92.19％and 94.23％,respectively,with no statistical significance(P＞0.05).The total duration of caffeine citrate injection were(60.53±8.92)and(48.17±5.24)days,respectively;the corrected gestational age at withdrawal were(36.02±1.56)and(33.18±1.27)weeks,respectively.The corrected gestational age were(34.31±0.48)and(32.06±0.51)weeks;the milk volume were(32.69±2.14)and(23.85±1.69)mL,respectively,with statistical significance(all P＜0.05).The starting age of caffeine citrate injection were(59.65±3.42)and(58.35±3.11)h in the long course group and the routine course,respectively,with no statistical significance(P＞0.05).Before treatment,the NBNA score of the long course and routine courses were 36.49±6.78 and 35.58±4.22,respectively;the NBNA score of long course and conventional course after treatment were 43.25±6.88 and 44.12±7.42,respectively.Compared with before treatment,NBNA score in both groups were higher after treatment,with statistical significance(all P＜0.05).There was no significant difference in NBNA score between the long course group and the routine course(P＞0.05).The incidence of bronchopulmonary dysplasia(84.38％vs 51.92％)and decreased hemoglobin concentration(17.75％vs 5.77％)in the long course group were significantly higher than those in the routine course(all P＜0.05).Conclusion Long-term use of caffeine citrate injection to correct gestational age＞34 weeks has no significant effect on clinical treatment,neurological function and intellectual development of very low birth weight infants.

OBJECTIVETo explore the exfoliated cancer cell contamination in different surgical materials during the malignant gastrectomy.

METHODSNinety gastric cancer patients undergoing gastrectomy were prospectively enrolled in this study. The operation materials of these 90 gastrectomy were divided into 5 groups: surgical instruments (A), gloves for surgeons (B), gloves and gauzes of scrub nurse (C), gauzes for hemostasis (D), anastomosis instrument (E). The rinse fluid of materials was cultured to verify positive cancer cells. Associations among different pathological stages, differentiations, materials and positive cancer cells rates were examined.

RESULTSStage II and III patients had higher positive rates of exfoliated cancer cell contamination than stage I patients [26.5 (9/34) and 47.5% (21/46) vs. 10.0% (1/10),P=0.046]. Low differentiated adenocarcinoma group had higher positive rate than moderately and well differentiated adenocarcinoma groups [44.8% (26/58) vs. 16.7% (4/24) and 12.5% (1/8), P=0.020]. Positive cancer cell rates of 5 kinds of materials were as follows: 12.2% (11/90) in A group, 6.7% (6/90) in B group, 22.2% (20/90) in C group, 15.6% (14/90) in D group and 3.3% (3/90) in E group, and the differences were significant (P<0.01).

CONCLUSIONDifferent operation materials have different risks to be contaminated by cancer cells, which is associated with the contact frequency, cancer staging and pathological classification.

OBJECTIVEEpilepsy with myoclonic absences (EMA) is a type of childhood epilepsy characterized by a specific seizure type, i.e. myoclonic absences (MA). This study aimed to investigate the clinical and electrophysiological characteristics of EMA.

METHODVideo-EEG monitoring was carried out in 6 patients with EMA, and 2 of them were examined with simultaneous deltoid muscle surface electromyogram (EMG). The clinical and EEG characteristics, treatment and prognoses of EMA were analyzed.

RESULTOf the 6 patients, 3 were female, and 3 were male. The age of onset was from 2 years and 3 months to 11 years (average 5 years and 2 months). MA was the sole seizure type in 5 patients. One patient presented generalized tonic clonic seizures (GTCS) at the onset and then switched to MA. The manifestations of MA included an impairment of consciousness of variable intensity, rhythmic myoclonic jerks with evident tonic contraction mainly involving the upper extremities, a deviation of head and body to one side or asymmetrical jerks observed in some cases, a duration ranging from 2 to 30 s, an abrupt onset and termination, a high frequency of attacks, at least several times to over 30 times per day, and easily provoked by hyperventilation. The ictal EEG consisted of rhythmic 3 Hz spike and wave discharges that were bilateral, synchronous and symmetrical in all patients. The deltoid muscle EMG recording in 2 patients showed rhythmic myoclonus at the same frequency as the spike and waves. The interictal EEG showed generalized spike and wave discharges in all patients, and focal discharges in some patients. Valproate was the drug of choice, which was often combined with other antiepileptic drugs. The ages at follow up ranged from 6 years and 4 months to 19 years. Seizures were controlled from 8 months to 3 years in 4 cases. The treatment at the onset was late in one case and was irregular in another who had GTCS during the course of the disease. These two cases were followed up for 2 years and 6 months and 5 years, respectively. Seizures could not be controlled in the 2 patients with intellectual impairment.

CONCLUSIONEMA was a rare type of childhood epilepsy characterized by MA. Clinical observation and ictal video-EEG and EMG were essential to diagnose EMA. Valproate alone or combined with other antiepileptic drugs given early could have a favorable effect to EMA. Delayed therapy and the presence of GTCS might suggest poor prognosis.
