Objective To investigate the adverse reactions and survival rate of low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in treatment of elderly patients with primary hepatic carcinoma.Methods A total of 84 patients with primary liver cancer were enrolled and randomly divided into low dose group and high dose group.Patients received 40 mg/m2 and 80 mg/m2 of Oxaliplatin respectively,and adverse reactions and survival rate were compared between the two groups.Results Incidence of nausea and vomiting was obviously lower and the number of patients with pain scale above 6 was significantly smaller in low dose group than in high dose group,with statistically significant differences (11.9％ vs.21.4％ and 28.6％ vs.78.6％,x2 =9.910,20.056,both P ＜ 0.05).White blood cell count was significantly higher and alanine aminotransferase (ALT) was significantly lower in low dose group than in high dose group after treatment (t =13.447,6.774,both P＜0.05).1 year and 3 year survival rate was 69.05％ and 30.95％ in low dose group and 61.9％ and 21.43％ in high dose group,respectively,with no statistically significant difference (x2 =0.474 and 0.985,P=0.491 and 0.321).Conclusions Low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in the treatment of elderly patients with primary hepatocellular carcinoma is worth to be promoted in clinical application because it does not affect the patient survival rate and the toxic effects of the chemotherapy are very little.

ObjectiveTo observe the effect of enema with Chinese medicine Changduqing combined with plasma exchange for treatment of endotoxemia in patients with acute-on-chronic liver failure.Methods A prospective randomized controlled trial was conducted, and 68 patients with acute-on-chronic hepatic failure who were hospitalized from January 2009 to June 2012 in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were randomly divided into treatment and control groups, 34 cases in each group. The patients in control group were treated with plasma exchange combined with western medicine comprehensive treatment such as protecting liver, reducing enzyme, removing jaundice, and in cases with hepatitis B, antiviral therapy was added. The treatment in patients of treatment group was the same as that in the control group, but additionally Changduqing enema of TCM decoction was given(ingredients: radix et rhizoma ginseng 10 g, flos magnolia officinalis 6 g, radix et rhizoma rhei 6 g, fructus aurantii immaturus 6 g, radix paeoniae rubra 10 g),twice a day combined with 3-4 times of plasma exchange treatment, once every 72 hours. The course of treatment of both groups was 4 weeks. The changes of total bilirubin (TBil), alanine aminotransferase(ALT), albumin(ALB), prothrombin activity(PTA), endotoxin, the improvement of clinical symptoms and signs such as lacking in strength, poor appetite, abdominal distension, oliguria, bleeding tendency, hepatic encephalopathy, infection and ascites were observed before and after treatment, and the survival rate in 24 weeks of follow-up was also investigated.Results Before treatment, the comparisons of TBil,ALT, ALB and PTA between the two groups were of no statistically significant differences(allP>0.05); compared with those before treatment, the levels of TBil and ALT were obviously decreased, and PTA was markedly increased after treatment in both groups, the degree of change being more prominent in treatment group〔TBil(μmol/L): 89.6±52.3 vs. 124.6±64.4, ALT(U/L):52.4±32.1 vs. 98.3±42.5, PTA:(53.8±11.5)% vs.(41.2±10.2)%, allP<0.05〕. The ALB levelsbefore and after treatment of both groups showed no significant difference(bothP>0.05). After treatment, the endotoxin(kU/L) in both groups were decreased in inchoate, developing and fully-developed stages and the descent being more significant in treatment group(inchoate stage: 0.094±0.015 vs. 0.109±0.032, developingstage: 0.102±0.019 vs. 0.146±0.062, fully-developed stage: 0.124±0.022 vs. 0.196±0.074, allP<0.05). The 24-week survival rates of developing and fully-developed stages in patients of both groups were lower than the rate in patients of inchoate stage, and the rates of treatment group in inchoate and developing stages were remarkably higher than the rate in control group〔inchoate stage: 94.1%(16/17) vs. 83.3%(15/18), developed stage: 85.7%(12/14) vs. 42.9%(6/14),bothP<0.01〕.ConclusionEnema with TCM Changduqing combined with plasma exchange for treatment of patients with acute-on-chronic liver failure can remove bilirubin, ameliorate endotoxemia, elevate PTA level and increase the survival rate of patients in 24 weeks of follow-up.

Objective To investigate the adverse reactions by stereotactic body radiation therapy(SBRT)for advanced hepatocellular carcinoma and summarize nursing experience.Methods Forty-one patients with advanced hepatocellular carcinoma from the radiation department of Sun Yat-sen University Cancer Center from July 2010 to May 2012 were enrolled in this retrospective study.The adverse reactions were closely observed and the patients were given pertinent nursing.Results The effectiveness rate was 56.2%.During the therapy,36 patients developed nausea/vomiting of grade 1-2,taking up 87.8%,18 had grade 1-3 elevation of liver enzymes,taking up 43.9%,16 had grade 1-2 decrease of white blood cells,taking up 39.0%,8 had grade 1 anemia,taking up 19.5%and 21 had grade 1-2 decrease of blood platelet,taking up 51.2%.The adverse reactions were contained satisfactorily through careful observations and pertinent nursing.Conclusions The toxic reactions by SBRT are nausea,vomiting,enzymes elevation and decrease of whole blood cell.Therefore,nurses need to observe these toxic reactions carefully and give pertinent care to the patients so as to prevent the complications,especially radiation-induced liver injury.

Objective To study the relationship between placenta HBsAg in HBsAg positive pregnant women and serum hepatitis B virus (HBV) markers,HBV DNA levels in newborns.Methods Placenta HBsAg was detected by immunohistochemical affinity hormone-biotin complex (ABC) method in 155 HBsAg positive pregnant women.Serum HBV markers in newborns were detected by enzyme-linked immunosorbent assay (ELISA).Serum HBV DNA levels of newborns were detected by real-time fluorescence quantitative polymerase chain reaction (PCR).The positive rates were compared using x2 test.Results HBsAg was expressed with different levels in various types of cells of placenta in 155 pregnant women.The total placenta HBsAg positive rate was 37.4％ (58/155),and those in decidual cells,trophoblastic cells,villous mesenchymal cells and villous capillary endothelial cells were 37.4％ (58/155),25.8％ (40/155),18.7％ (29/155) and 7.1％ (11/155),respectively.The HBsAg positive rates of placenta gradually decreased from decidual cells of the maternal surface to villous capillary endothelial cells of the fetal surface (tendency x2 =43.01,P=0.00).The positivity of placenta HBsAg was associated with both HBsAg and HBeAg in newborns (x2 =4.88,P＜0.05 and x2 =3.86,P＜0.05,respectively),while that was not associated withanti-HBe and anti-HBc in newborns (x2 =3.36,P＞0.05 and x2 =0.00,P＞ 0.05,respectively).The risk of HBsAg positive in newborns was higher when HBsAg was positive in villous capillary endothelial cells and villous mesenchymal cells (OR=5.31,95 ％CI=1.38-20.40 and OR=3.33,95％CI=1.16-9.52,respectively).The risk of HBeAg positive in newborns was higher when HBsAg was positive in trophoblastic cells and villous mesenchymal cells (OR=3.04,95 ％CI=1.45-6.39 and OR=3.05,95 ％ CI=1.32-7.03,respectively).However,placenta HBsAg positive was not associated with HBV DNA positive in newborns (x2 =0.09,P＞0.05).Conclusion The risk of neonatal HBV serological markers positive is higher when the HBsAg positive placental cells are closer to fetal surface,which indicates that HBsAg enters fetal blood circulation by means of cell transferring layer by layer.

ObjectiveTo observe the role of Sijunzi decoction on the gut barrier protection and immunity regulation in spleen-qi deficiency type patients with persistent inflammation-immunosuppression catabolism syndrome (PICS).Methods A prospective study was conducted, and according to random number table, 46 patients with PICS accompanied by spleen-qi deficiency admitted to Department of Critical Care Medicine of Beijing Shijitan Hospital of Capital Medical University were randomly divided into two groups: control group and Sijunzi decoction group(each 23 cases). Conventional therapy was given to both groups, and the patients in Sijunzi decoction group were additionally treated with modified Sijunzi decoction 100 mL by nasal feeding, while those in the control group were treated with an equal amount of warm boiled water by nasal feeding. The course of treatment was 2 weeks in both groups. The improvement in traditional Chinese medicine(TCM) syndrome and gastrointestinal function was observed in two groups before and after treatment. At the same time, the changes of lymphocyte subsets including total T cells(CD3+ cells),helper/inducer T cells(CD3+/CD4+T cells), suppressor/cytotoxic T cells(CD3+/CD8+ T cells), CD4/CD8, total natural killer cells(NK cell,CD3-/CD16+CD56+ cells),natural killer like T cells(NK T cell,CD3+/CD16+CD56+ T cells),total B cells(CD19+ cells),regulatory T cells(Treg T cells, CD4+/CD25+ T cells),suppressor T cells(CD8+/CD28- T cells) and cytotoxic T cells(CD8+/CD28+ T cells)were analyzed.Results① There were no differences in the acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,acute gastrointestinal injury(AGI)grades and peripheral blood lymphocyte subsets between Sijunzi decoction group and control group before treatment( allP>0.05).② After 2 weeks of treatment, all the patients' clinical symptoms of spleen-qi deficiencywere improved, and there was no difference in effect between the Sijunzi decoction and control group(valid:11 cases vs. 6 cases, invalid:12 cases vs.17 cases, bothP>0.05) . In both groups, the patients' AGI condition was improved, but the improvement in treatment group was more significant than that in the control group(valid: 14 cases vs. 7 cases, P<0.05) .③ In the control group,the numbers of CD3+, CD3+/CD8+,CD8+/CD28- T cells after treatment were increased significantly〔CD3+:(62.37±7.83)% vs.(54.08±11.65)%, CD3+/CD8+:(31.52±10.55)% vs. (23.94±9.22)%, CD8+/CD28-:(24.97±10.25)% vs.(16.78±10.55)%〕 and CD19+ number was decreased obviously〔(5.78±5.33)% vs.(9.73±8.02)%〕 at the same time(allP<0.05). After treatment, in the Sijunzi decoction group, the numbers of CD3+,CD3+/CD4+, CD3+/CD8+, CD8+/CD28-, CD8+/CD28+ T cells were increased significantly compared with those before treatment〔CD3+:(74.53±7.64)% vs.(52.98±10.05)%, CD3+/CD4+:(36.27±12.08)% vs.(30.00±8.60)%, CD3+/CD8+:(37.33±12.56)% vs.(22.88±9.97)%, CD8+/CD28-:(26.89±10.80)% vs.(17.01±9.48)%, CD8+/CD28+:(12.08±5.50)% vs.(8.47±4.29)%〕, and total CD19+ number was decreased remarkably at the same time〔(4.60±4.28)% vs.(9.86±8.61)%,P<0.05〕. In the Sijunzi decoction group, after 2 weeks of treatment, the number of CD3+ T cells was increased more significantly than that in the control group〔(8.29±9.28)% vs.(5.80±5.33)%,P<0.05〕.ConclusionUsing Sijunzi decoction combined with conventional therapy can improve the clinical symptoms of patients with PICS accompanied by spleen-qi deficiency and gastrointestinal dysfunction, the mechanism is possibly via enhancing immunity by regulating the numbers of B and T lymphocytes, and maybe the cell-mediated immunity plays a more prominent role.

Objective To study the relationships between serum hepatitis B virus (HBV) DNA level in chronic HBV infected mothers, free maternal DNA in newborns' peripheral blood and HBV infection of newborns. Methods Free maternal DNA in newborns' peripheral blood was amplified by allele-specific polymerase chain reaction (As-PCR) and heminested polymerase chain reaction (heminPCR). Serum HBV DNA of pregnant women were detected by fluorescence quantitative real-time PCR. The relationships between mothers' serum HBV DNA level, mother-to-fetus DNA transfer and newborns HBV infection were analyzed by SPSS 13. 0 software. Results Thirty-six pairs of motherfetus informative cases were selected and free maternal DNA in the peripheral blood was detected in 26newborns (72. 2%). Statistical analysis indicated that mother-to-fetus DNA transfer was not related with HBsAg, HBV DNA DOsitive in newborns (Fisher exact Drobabilities were 0. 278 and 1.000,respectively; both P > 0. 05), while it was related with HBV infection in the peripheral bloodmononuclear cell (PBMC) of newborns (Fisher exact probability was 0. 026, P<0. 05). Freematernal DNA transfer was not related with mother HBV DNA level (X2 = 2. 097, P>0. 05). Therisk of HBV DNA positive in newborns increased with mother serum HBV DNA increasing ( total X= 62. 21, P<0. 05; tendency X2 =58. 46, P<0. 05). There was no relationship between motherserum HBV DNA level and PBMC HBV DNA positive in newborns (total X2 =4. 82, P>0. 05).Conclusions DNA transfer from HBV infected mother to fetus is related with PBMC HBV infection innewborns, which could be a risk factor of HBV infection in newborns. The risk of serum HBV DNApositive in newborns increases with mother serum HBV DNA level increasing.

Objective To evaluate the surgical techniques and clinical applications of single-port transumlilical laparoscopic dismembered pyeloplasty for the treatment of ureteropelvic junction obstruction (UPJO). Methods From August 2009 to March 2010, 15 patients were treated with single-port transumbilical laparoscopic dismembered pyeloplasty. There were 12 males and 3 females,aged 12 to 55 years with an average age of 20 years, who were diagnosed by diuretic renography,IVU, and MRU et al. A single umbilical incision of 3. 5cm was made for single-port trocar and a flexible-tip 0°digital video-laparoscope was used in all cases. The procedures were performed according to the methods used in classical laparoscopic dismembered pyeloplasty with general instruments. ResultsAll operations were performed successfully without conversion to open surgery. The mean operative time was 90 (75-145) min, and the mean hospital stay length was 6 days. No organs injury occurred during operation, and no urine leakage was found afer operation. The symptoms of low back pain disappeared and hydronephrosis reduced apparently or dispeared without any anastomotic stenosis after follow-up of 4-6 months. Conclusions Single-port transumbilical laparoscopic dismembered pyeloplasty is feasible, effective and safe for the treatment of UPJO.

Objective To investigate the effect of median nerve electrical stimulation on the activity, speech and quality of life in patients after severe traumatic brain injury. Methods 60 patients with severe traumatic brain injury were divided into 2 groups: the control group (A) and the treated group (B). The patients in Group A were treated with the routine medicine and rehabilitation. Based on the routine therapy, the patients in Group B were treated with the right median nerve electrical stimulation. Their outcome, activity, speech and quality of life were assessed. Results The scores of Glasgow Outcome Scale (GOS), speech assessment, and the quality of life in Group B improved compared with that in Group A (P<0.05), the activity seemed to improve, but not significantly. Conclusion The right median nerve electrical stimulation is effective to promote the recovery of neurological function and improve the quality of life in patients with severe traumatic brain injury.

Traditional Chinese medicine (TCM) safety assessment is an important content of post-marketing Chinese herbal medicine assessment and the primary question. It includes safety monitoring and safety evaluation. China has established the elementary system for the TCM safety monitoring, but did few things on safety evaluation. People have knew that the methods of pharmacoepidemiology have good practicability on drug safety assessment in recent years. This article analyzed three methods of pharmacoepidemiology used in post-marketing Chinese herbal medicine safety assessment. There are three examples that may give some suggestions to fellow doctors working for safety monitoring and evaluation of TCM.
