OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95％ confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95％ CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95％CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95％CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95％CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95％CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95％CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95％CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

OBJECTIVEIdiopathic collapsing glomerulopathy (ICG) is a clinically and pathologically distinct variant of focal segmental glomerulosclerosis, which is characterized by proteinuria (often nephrotic range) and rapid progression to end-stage renal failure. The typical pathological changes are global/segmental glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. Most ICG patients who have been reported in previous published papers are adults. ICG in children is rare. The study aimed to analyze and investigate clinical manifestations, renal histopathological findings, treatment and outcomes of ICG in children.

METHODSData of two cases of ICG, a 7-year-old boy and a 12-year-old girl, were analyzed. Both of them were Chinese and Han. Clinical characteristics, results of laboratory tests, renal histopathological findings, treatment, outcomes and prognosis of the two children with ICG were retrospectively analyzed. Results were compared with published data.

RESULTSThese two children presented typical clinical features of nephrotic syndrome. The quantity of 24 hr urine protein was 7.6 g/d (0.47 g/kg x d for boy) and 10.67 g/d (0.35 g/kg x d for girl). Both of them had hypertension (blood pressure ranged from 130/90 to 150/110 mmHg) and hypercholesterolemia (15.4 mmol/L for the boy and 11.3 mmol/L for the girl). The serum albumin was 12 g/L for girl and 23 g/L for boy. The creatinine clearance rate gradually decreased from normal range to 30 ml/min for the girl. The histopathological changes in renal biopsy of them were focal segmental or global glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. These two cases were steroid-resistant and were treated with pulse intravenous methylprednisolone and pulse intravenous cyclphosphamade in one case, who rapidly progressed to end-stage renal failure and died half a year later. Another one was treated with cyclosporine. He showed continuous hypertention and heavy proteinuria for eight months.

CONCLUSIONICG in the 2 children was a severe disease which presented steroid-resistant nephrotic syndrome and rapidly progressive renal failure. The pathological characteristics was global/segmental glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. In children with ICG treatment was difficult and the prognosis was poor.

OBJECTIVETo compare the clinical outcomes of intrasacrospinal muscular approach and posterior midline approach in treating far lateral lumbar disc herniation.

METHODSThe clinical data of 32 patients with far lateral lumbar disc herniation underwent transforaminal lumbar interbody fusion from January 2004 to January 2011 were retrospectively analyzed. The patients were divided into intrasacrospinal muscular approach group (11 males and 6 females ) and posterior midline approach group (10 males and 5 females). All patients were followed up from 12 to 18 months with an average of 15.3 months. Operative time, blood loss, postoperative draining volume were recorded and pre-and post-operative visual analog scale (VAS) and Oswestry Disability Index (ODI) were compared between two groups.

RESULTSOperative time, blood loss, postoperative draining volume in intrasacrospinal muscular approach group was less than that of posterior midline approach group (P < 0.05). There was no significant difference in VAS at final follow-up between two groups (P > 0.05); and the mean ODI in intrasacrospinal muscular approach group was less than that of posterior midline approach group (P < 0.05).

CONCLUSIONFor the treatment of far lateral lumbar disc herniation, intrasacrospinal muscular approach has less injury for paraspinal muscle and more satisfactory clinical outcome and is better method than posterior midline approach.

OBJECTIVESBy studying the possibility and degree of the replication and expression of human hepatitis B virus (HBV) genes in normal liver cells from heterogenous species, such as primary duck hepatocytes (PDH) and primary rat hepatocytes (PRH), to investigate the species-specificity of HBV infection and replication.

METHODSPDH and PRH isolated by in situ perfusion with low concentration collagenase were transfected with complete HBV genome by electroporation (transfection group, about 1.19 10(12) copies of linear HBV DNA/1 10(7) PRH/PDH). From 1 day to 15 days after transfection, HBsAg and HBeAg in the supernatants and lysates of PRH/PDH were measured with IMX System, HBcAg was assayed with western blotting, Immunol dot blotting and Immunocytochemistry. Moreover, HBV S-mRNA and X-mRNA were tested with RT-PCR. Meanwhile, replicative intermediates of HBV DNA were analyzed by Southern blotting and Dot blotting. PRH/PDH electroporated only was used as control group.

RESULTSHBsAg in the lysates of transfected PDH group were 15.24 (1day), 14.55 (3 days) and 5.13 ( 5 days; P/N values, positive>or=2.1), HBeAg all was negative (<2.1), and both were negative in the supernatants of transfected group. Viral antigen production in transfected rat hepatocytes: HBsAg in the lysates of transfected hepatocytes was positive, P/N values ranging from 2.17 to 93.41, The average P/N values was 14.74+/-31.82, and could be maintained for 15 days after transfection. Whereas, HBsAg in the supernatants of transfected group was only found positive on 1 day after transfection, which P/N value was 6.66. HBeAg and HBcAg in the lysates of PRH of transfection group were positive during the first 3 days following transfection, P/N values was around 2.8. The total amount of HBV DNA in the transfected PDH and PRH groups was strongly positive by dot blotting, whereas that of the control group was negative. Southern blot analysis of intracellular total HBV DNA indicated that there were relaxed circular (RC), covalently closed circular (ccc) and single-stranded (SS) HBV DNA replicative intermediates in the transfected PDH and PRH groups, there was no integrated HBV DNA in the cellular genome. Control groups were negative at all.

CONCLUSIONExpression of HBV genes and production can occur in hepatocytes from nonmammalian species or mammalian species, which strongly supports the idea that replication of HBV has no critical species-specificity, and yet it depends on the endoenvironment of hepatocyte.

OBJECTIVETo observe the incidence of elimination delay in high dose methotrexate (HDMTX) therapy, its side effects and influence to next course of chemotherapy and analyze the relationship between the dosage, the duration of MTX infusion and the morbidity of the elimination delay.

METHODSA total of 121 childhood acute lymphoblastic leukemia (ALL) (497 infusions of HDMTX) were analysed in this study. The elimination delay rate and the adverse effects in different dose groups (3 g/m2 vs 5 g/m2) and different infusion duration groups (7 h vs 24 h) were compared. The adverse effect evaluation was based on the World Health Organization (WHO) Toxicity Grading Criteria. The rescue dosages of calcium folinate (CF) among these groups were compared through CF/MTX index.

RESULTSThe overall morbidity of elimination delay was 12.1% with a relative risk of 30.6% for the first time. The relative risk for the second time of occurrence was increased to 45.9% (P < 0.01) and it was not significantly increased for the third time (35.3%). Children with elimination delay had lower platelet count (P < 0.01) and higher CF rescue dosage (P < 0.01), while the damage of oral mucous membrane was more severe (P < 0.05) and the next course of chemotherapy would be postponed for a median of 4 days in 3 g group. There was no significant difference in elimination delay rates between 3 g and 5 g groups (12.1% vs 12.0%, P > 0.05), and between 7 h and 24 h MTX infusion groups (13.6% vs 11.9%, P > 0.05). The only side effect occurred in 5 g group was gastrointestinal morbidity. The CF/MTX index of 5 g group without elimination delay was less than that of 3 g group (P < 0.01).

CONCLUSIONElimination delay in HDMTX therapy accompanies the suppression of bone marrow and damage of oral mucous membrane, which need more CF rescues and will postpone the following course of chemotherapy. Elimination delay is not associated with the duration of the infusion and the dosage of MTX within the range of 3 approximately 5 g/m2 but there are individual differences.

OBJECTIVETo study the molecular characteristics of Noroviruses causing outbreaks of acute gastroenteritis in Huzhou.

METHODSFrom 2008 to 2010, total 119 fecal specimens collected from outbreaks of acute gastroenteritis were tested for Norovirus. Partial sequence of RNA dependent RNA polymerase (RdRp) of the positive samples were amplified by RT-PCR, then the PCR production were purified, sequenced and put into phylogenetic analysis.

RESULTS50 of 119 specimens were positive for Norovirus by real-time RT-PCR. Out of those 50 Norovirus positive specimens, 9 were Norovirus Genogroup I (GI) positive, 35 were Norovirus Genogroup II (GII) positive, 6 was both Norovirus GI and GII positive. 12 PCR products for RdRp were selected for further studies on sequencing. Phylogenetic analysis revealed that the 5 GI norovirus isolates were belonged to genotype GI/2 and GI/3. Of the 7 GII norovirus isolates, 6 were belonged to genotype GII/4, 1 was belonged to genotype Glib.

CONCLUSIONNorovirus is a major cause of outbreaks of acute gastroenteritis in Huzhou and the epidemic strains of norovirus isolated from Huzhou had a high degree of genetic diversity.
