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.

OBJECTIVETo study the changes of serum interleukin-2 (IL-2), interleukin-8 (IL-8) and immunoglobulin (IgG, IgA, IgM) in patients with esophageal cancer, and to probe the relationship between the levels of IL-2, IL-8, IgG, IgA and IgM and the progress of cancer.

METHODSThe serum levels of IL-2 and IL-8 were detected by enzyme-linked immunosorbent assay for 72 case of primary esophageal cancer, 68 advanced esophageal cancer and 120 healthy controls, and the level of immunoglobulin (IgG, IgA, IgM) in patients with esophageal cancer was dynamically observed.

RESULTSThe IL-2 level in patients with early esophageal cancer [(1.69 +/- 0.53) ng/ml] or late esophageal cancer [(1.11 +/- 0.60) ng/ml] was lower than the control group [(2.78 +/- 0.51) ng/ml] (P < 0.01), the late esophageal cancer group was lower than early esophageal cancer group (P < 0.05). The level of IL-8 in patients with early esophageal cancer [(85.48 +/- 6.14) ng/L] or late esophageal cancer [(121.41 +/- 6.22) ng/L] was much higher than the control group [(54.48 +/- 12.20) ng/L] (P < 0.01), the late esophageal cancer group was much higher than early esophageal cancer group (P < 0.01); There was correlation between the levels of IL-2 and IL-8 and the worsen-extent of the tumour in patients with early esophageal cancer or late esophageal cancer. But the level of IgG [(12.23 +/- 2.50) g/L], IgM [(1.60 +/- 0.80) g/L] in the patients with esophageal cancer compared with the level of IgG [(11.65 +/- 3.70) g/L], IgM [(1.46 +/- 0.71) g/L] in the health control group have no significant difference (P > 0.05), the level of IgA [(3.50 +/- 1.10) g/L] in patients with esophageal cancer Compared with the control group [(1.88 +/- 1.08) g/L] has significant difference (P < 0.01), and along with the worsen-extent of the tumor in patients the level of IgA has the increased tendency.

CONCLUSIONThe IL-8 might accelerate the pathogenesis of esophageal cancer, and the IL-2 might restrain. The positive correlation between the level of IgA and the patients with esophageal cancer is observed in this study; the immune maladjustment of IL-2, IL-8 and IgA might be correlative to esophageal cancer, and the IL-2, IL-8 and IgA levels might be an available index for the severity of esophageal cancer, Which may be of some help for clinic practitioners to judge the progress, curative effect and prognosis of the cancer.

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.

Objective To investigate the protective effect of modified Qianjin Weijing Decoction(MQJWJD)on TNF-α and NF-κB in rats with lung injury induced by particulate matter; To discuss relevant mechanism of action. Methods A tracheal drip 15 mg/kg fine particles of saline solution was used to establish modeling, every other day, three times. Thirty-two Wistar rats were randomly divided into normal group, model group and MQJWJD high-dose and low-dose groups, with eight rats in each group. Medication groups were given relevant medicine for gavage. The level of TNF-α in bronchoalveolar lavage fluid (BALF) was measured by ELISA. The expression of NF-κB protein in lung tissues was measured by immunohistochemistry. The histopathology of the lung injury was observed by light microscope. Results Compared with normal group, the level of TNF-α and the expression of NF-κB protein in the model group were higher than those in the normal group (P<0.01). Compared with model group, the level of TNF-α and the expression of NF-κB protein in MQJWJD low-dose and high-dose groups were lower than those in the model group (P<0.05, P<0.01). Pathological observation showed that, compared with normal group, model group showed intratracheal, alveolar and interstitial bacteria within a large number of fine particles calm, alveolar and pulmonary interstitial visible large amounts of phagocytic fine particles of macrophages and accompanied by more neutrophils and lymphocyte infiltration; Lung tissue pathological changes were significantly lighter in MQJWJD high-dose and low-dose groups than the model group. MQJWJD high-dose group showed mild inflammation, alveolar and pulmonary interstitial visible phagocytic fine particles of macrophages, a small amount of neutrophils and lymphocyte infiltration. Conclusion MQJWJD can reduce the pulmonary injury in rats induced by particulate matter and has protective effects on the rat model through decreasing the levels of TNF-α and the expressions of NF-κB protein in injured lung tissues.

OBJECTIVETo assess the influences of continuous femoral nerve block (CFNB) and patient-controlled intravenous analgesia (PCIA) on postoperative pain scores,knee rehabilitation,and stress response after total knee arthroplasty (TKA).

METHODSTotally 32 adult patients scheduled for elective total knee arthroplasty were equally randomized into CFNB group or PCIA group. Intraoperative hemodynamics and fentanyl dose were recorded. Pain was assessed at rest and during continuous passive motion (CPM) using a visual analog scale at post-anesthesia care unit (PACU) and 4, 8, 12, 24, and 48 hours postoperatively. Morphine consumption was also recorded. As indicators of stress and inflammatory response,the leukocyte count, serum lactic acid, blood glucose, serum C-reactive protein (CRP), and serum cortisol were determined on admission, to operation room, immediately after skin incision, before extubation,on post-operation day 1 (POD1), and on POD2.

RESULTSCFNB group showed significantly lower heart rate compared with PCIA group 60 minutes and 90 minutes intraoperatively (Pü0.05). Intraoperative consumption of fentanyl was significantly lower in CFNB group (137.5∓44.4) μg than in PCIA group (264.1∓67.1) μg (Pü0.01). The CFNB group showed significantly lower VAS scores both at rest and during CPM compared with PCIA group at all time points (Pü0.05). Morphine consumption was significantly lower in CFNB group than in PCIA group at different time points (Pü0.05 or Pü0.01). The maximal continuous passive motion amplitude of CFNB group were significantly larger than that of PCIA group on POD1 [(55.0∓9.4) vs.(44.6∓9.9), P[(76.3∓11.0) vs. (67.5∓10.3), P<0.05]. The incidences of somnolence and nausea/vomiting in CFNB group were 37.5% and 37.5%, respectively,which were significantly lower than those of PCIA group (75.0% and 81.3%) (Pü0.05). Patient satisfaction scores on anesthesia and post-operative analgesia was significantly higher in CFNB group than in PCIA group (93.1∓7.9 vs. 79.1∓11.9, respectively) (Pü0.05).

CONCLUSIONAfter TKA,CFNB technique provides more stable intraoperative hemodynamics than PCIA, with better pain relief,faster postoperative knee rehabilitation,less side effects,and higher patient satisfaction.

OBJECTIVETo verify whether abnormal expression of calcium/calmodulin dependent serine protein kinase (CASK) and inhibitors of differentiation 1 (ID1) exist in Fb of keloid, and to observe the effect of artesunate on two genes.

METHODSFifteen samples of keloid and 12 samples of normal skin tissue (discarded) excised from patients admitted to our hospital were collected. Tissue particle adherent method was used in the primary culture of Fb, and cells from the third to the eighth passage were used for test. Expressions of CASK and ID1 in Fb harvested from both sources were observed with immunofluorescence staining. Fb of keloid were stimulated with artesunate in various concentration for different time, and the median inhibitory concentration (IC50) was determined with the MTT colorimetric assay, which served as the intervention concentration of artesunate. Fb of normal skin were set as normal control group (NC, treated with medium solution). Fb of keloid were divided into scar control group (SC, treated with medium solution) and scar administration group (SA, treated with artesunate in IC50). The cycle and apoptosis of Fb were detected with flow cytometric assay, and the nucleic acid and protein expressions of CASK and ID1 of Fb in each group were determined with RT-PCR and Western blotting. Data were processed with one-way analysis of variance and LSD-t test.

RESULTSExpressions of CASK and ID1 were detected in two kinds of Fb. The concentration of 75 mg/L was selected as the intervention concentration of artesunate. (1) There were statistically significant differences among the three groups in the percentages of cells in G0/G1 phase and G2/M phase (with F values respectively 118.064 and 163.840, P values all below 0.01). The percentage of cells in G0/G1 phase of group SA was (91.4 ± 1.4)%, which was significantly higher than that of group SC and group NC [respectively (80.7 ± 0.3)% and (82.4 ± 0.6)%, with t values respectively 12.740 and 9.872, P values all below 0.05]. The percentage of cells in G2/M phase of group SA was (6.9 ± 0.3)%, which was significantly lower than that of group SC and group NC [respectively (13.7 ± 0.3)% and (12.7 ± 0.8)%, with t values respectively 43.702 and 12.276, P values all below 0.05]. (2) There were statistically significant differences among the three groups in the early and late apoptotic rates (with F values respectively 61.879 and 4710.862, P values all below 0.01). The early and late apoptotic rates of group SA were respectively (7.1 ± 1.0)% and (14.9 ± 0.3)%, which were significantly higher than those of group SC and group NC [with early apoptotic rate respectively (2.6 ± 0.4)% and (2.7 ± 0.3)%, t values respectively 7.974 and 7.767, P values all below 0.05; with late apoptotic rate respectively (2.3 ± 0.3)% and (2.5 ± 0.4)%, t values respectively 72.882 and 69.792, P values all below 0.05]. (3) The mRNA expression of CASK in group SC was 0.658 ± 0.024, and it was lower than that of group NC (1.076 ± 0.008, t = 28.997, P < 0.01) and group SA (0.855 ± 0.008, t = 13.549, P < 0.01). The protein expression of CASK in group SC was 0.067 ± 0.007, and it was lower than that of group NC (0.179 ± 0.015, t = 12.042, P < 0.01) and group SA (0.132 ± 0.010, t = 9.498, P < 0.01). (4) The mRNA expression of ID1 in group SC was 0.416 ± 0.006, which was higher than that of group NC (0.317 ± 0.020, t = 8.299, P < 0.01) and group SA (0.217 ± 0.009, t = 32.417, P < 0.01). The protein expression of ID1 in group SC was 0.789 ± 0.034, and it was higher than that of group NC (0.366 ± 0.029, t = 16.341, P < 0.01) and group SA (0.114 ± 0.006, t = 33.978, P < 0.01).

CONCLUSIONSIt is speculated that CASK and ID1 participate in the proliferation of Fb in keloid. The mechanism of artesunate in inhibiting the proliferation of Fb in keloid may be related to the up-regulation of CASK and down-regulation of ID1.

OBJECTIVETo examine the relationship between intercellular adhesion molecule-1 (ICAM-1) gene polymorphism and ischemic stroke (IS) in Chinese Zhuang populations.

METHODSThe K469E polymorphism in the exon 6 of ICAM-1 gene was detected by polymerase chain reaction-restriction fragment length polymorphism analysis and DNA sequencing in 205 patients with IS of Zhuang nationality and in 210 healthy controls, and the serum level of ICAM-1 was determined by enzyme-linked immunosorbent assay.

RESULTSThe IS group showed significantly higher serum levels of ICAM-1 than did the control group (P < 0.01). There was significant difference in frequencies of allele and genotype in K469E polymorphism between IS and control groups, respectively (P < 0.05). The K allele carriers had 1.424 times the risk of suffering from IS as compared with the E allele carriers (OR = 1.424, 95% CI: 1.071 - 1.894); the serum ICAM-1 level of E allele carriers was significantly higher than that of K allele carriers (501.24 +/- 139.56 ng/ml vs 475.17 +/- 118.35 ng/ml, P < 0.01).

CONCLUSIONThere is an association between ICAM-1 gene K469E polymorphism and IS, and E allele may be a genetic risk factor of IS among Guangxi Zhuangs, in which the ICAM-1 E allele carriers may have up-regulated expression of ICAM-1 and hence are at a higher risk of ischemic stroke.

OBJECTIVETo understand and master the situation in which enterovirus caused hand-foot-and-mouth disease (HFMD) in Xuzhou district in 2009 so as to provide scientific basis for the control and prevention of hand-foot-and-mouth disease.

METHODSThe researchers adopted fluorescence RT-PCR method to detect EV and EV71 as well as the CA16 specificity RNA from 222 samples of anal swabs and oropharyngeal swabs from the 240 cases who were diagnosed clinically as hand-foot-mouth disease infected by enterovirus. Also, the researchers conducted EV71-IgM antibody detection on 114 samples of acute phase serum with ELA method.

RESULTSAmong the 240 enterovirus infected patients, the total EV infection rate is 72.50% (174/240), among which EV71 infection rate is 57.92% (139/240), CoxA16 infection rate is 9.17% (22/240), and other EV infection rate is 5.42% (13/240). The EV71-RNA positive rate of the samples of 222 anus swabs among the 240 suspected enterovirus infected patients is 45.94% (102/222), the samples of swallow swab EV71-RNA positive rate is 25.68% (57/222) and the EV71-IgM antibody positive rate of 114 samples of acute phase serum is 86.84% (99/114). The EV71-RNA positive rate of oropharyngeal swabs of 254 healthy children is 1.57% (4/254) , and no CoxA16-RNA was detected. In the oropharyngeal swabs of 54 close contacts (medical personnel), the EV-RNA detected is negative. The positive rate of EV71-IgM antibody of the 258 healthy children's serum samples is 2.71% (7/258).

CONCLUSIONThe widespreading of hand-foot-mouth disease in Xuzhou district is caused mainly by type 71 enterovirus. Inapparent infection of type 71 enterovirus exists among children under the age of 3 during the time of widespreading period and IgM antibody develops in them. It is difficult for adults to be infected by EV71 even if they contact the contagion source closely. The positive rate of EV71-IgM antibody in the samples of acute phase serum of suspected cases is the highest (86.84%), and the second highest is the positive rate of RNA of EV71 of anal swabs (45.94%) and of the EV71 of oropharyngeal swabs (25.68%). ELA reagent kit is used in the early diagnosis of EV71 infection for it is easy to operate, fast and economic, so, it is worth popularizing in the grass-root medical units.
