BACKGROUND: Xingnao kaiqiao acupuncture is a series of systematic acupuncture methods with yin channels in domination, assisted by specified standards of quantity manipulation, which was founded according to the pathogenesis of stroke, and it is effective in treating stroke.OBJECTIVE: To observe the effects of xingnao kaiqiao acupuncture on blood lipids and blood viscosity in stroke patients of different syndrome types.DESIGN: A comparative observation.SETTINGS: Institute of Acupuncture and Moxibustion, and Special Care Ward of Acupuncture, the First Affiliated Hospital of Tianjin College of Traditional Chinese Medicine.PARTICIPANTS: Totally 750 stroke inpatients (466 males and 284 females) were selected from the Special Care Ward of Acupuncture, the First Affiliated Hospital of Tianjin College of Traditional Chinese Medicine between January and December in 2001, the average age was (64±12) years,the disease course ranged from 2 hours to 3 years. All the patients were informed and agree with the therapeutic program.METHODS: ① The traditional Chinese medicine (TCM) syndrome differentiations of stroke were in reference to the fifth edition of Traditional Chinese Medicine and Internal Medicine. There were 688 cases of stroke of meridian and collateral type and 47 cases of stroke attacking zang-fu organs type. ② Huatuo filiform needles produced by Suzhou [1.0-1.5 cun in length, 0.32-0.38 mm in diameter (No. 30-28)] were used in the xingnao kaiqiao acupuncture. Firstly, the acupoints of bilateral Neiguan were acupunctured perpendicularly for about 0.5-1.0 cun, the reducing manipulation by twirling as well as lifting and thrusting the needle was performed for 1 minute; Secondly, the needle was inserted at Renzhong towards nasal septum for about 0.3-0.5 cun, the manipulation of heavy bird-peck needling was used till the eyeballs were wet or tears fell down; Then Sanyinjiao was acupunctured, the needle was inserted along the medial border of tibia at an angle of 45° with skin for about 1.0-1.5 cun, the reinforcing manipulation by lifting and thrusting the needle was performed till the ipsilateral lower limb had three tics; The acupoint of Weizhong was selected by lying and lifting the leg, the needle was inserted perpendicularly for 0.5-1.0 cun, and the reducing manipulation by lifting and thrusting was applied till the ipsilateral lower limb had three tics; The acupoint of Jiquan was acupunctured at 1 cun below the source point along the channel in avoidance of axillary hairs, the needle was inserted perpendicularly for 1.0-1.5 cun, and the reducing manipulation by lifting and thrusting was applied till the ipsilateral upper limb had three tics; The elbow was flexed to 120° for acupuncture at Chize, the needle was inserted perpendicularly for 1.0 cun, the reducing manipulation by lifting and thrusting was applied till the ipsilateral upper limb had three tics. Twice a day for 7 days as a course. ③ After four courses averagely, the whole blood viscosities were detected with the hemorrheologic detector, and the normal ranges for lowshear, middle-shear and high-shear of whole blood viscosities were 6.50-9.25, 4.35-5.45 and 3.65-4.40 mpa ·s respectively. The levels of total cholesterol and triglyceride were detected with blood lipid detector, and the normal ranges were 3.38-6.5 mmol/L and 0.56-0.147 mmol/L.MAIN OUTCOME MEASURES: The effects of xingnao kaiqiao acupuncture on the blood lipids and blood viscosity in stroke patients of different syndrome types were observed.RESULTS: Totally 690 and 721 cases finished the detections of whole blood viscosities and blood lipids respectively. There were obviously fewer cases with normal whole blood viscosities in the patients with stroke of meridian and collateral than in those with stroke attacking zang-fu organs (10.3%, 15.4%, P ＜ 0.01), but markedly more cases with higher total cholesterol and triglyceride than in those with stroke attacking zang-fu organs (80.5%, 91.5%; 64.1%, 71.3%; P ＜ 0.01).CONCLUSION: The levels of blood lipids in the patients with stroke of meridian and collateral are more abnormal than in those with stroke attacking zang-fu organs, but their blood viscosities are better than in those with stroke attacking zang-fu organs.

Objective To investigate the relationship among the proliferation of CD4+T cells, the intracellular levels of interleukin-10 (IL-10) and transforming growth factor-?1(TGF-?1), and allergic bronchial asthma. Methods Dermatophagoides farinae antigen were prepared as allergen. Twenty-five patients with asthma and 15 healthy individuals were enrolled and divided into blank control group, allergen group and self control group, respectively, after venous blood sample collection. The proliferation of CD4+T cells and the distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 were measuredby flow cytometry (FCM). Results The distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 could hardly be detected in the peripheral blood samples of the blank controls of the patients with asthma and healthy ones. In the allergen group of the healthy individuals, the peripheral blood CD4+T cells were significantly proliferated, and the proportions of CD4+T cells andCD4+/IL-10+ cells were much higher than the self control group, while there was no significantly increase in the proportions of CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 subgroups. In the allergen group of those with asthma, the proportions of peripheral blood CD4+, CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 cells were not found significantly increased compared with those self controls. After being activated by allergen, the proportion of peripheral blood CD4+/IL-10+ cells was significantly lower in the patients with asthma than the healthy individuals(P

Objective:To analyze risk factors that were associated with loss of correction curvature after short-segment restoration and fixation in cases who had single-segment thoracolumbar fracture.Methods:87 Cases who had experienced single-segment thoracolumbar fracture and had underwent short-segment restoration and fixation in our department from Jan 2008 to Jan 2011,and had complete follow-up imaging were included.Cobb angles were measured on lateral thoracolumbar X-ray preoperatively,postoperatively and before removal of internal fixation.And these included the angle formed by vertebras that located above and below injured vertebrae (α angle),superior endplate of injured vertebrae and its superior vertebrae (β angle),inferior endplate of injured vertebrae and its inferior vertebrae (γ angle),inferior and superior endplate of injured vertebrae (δ angle).T-test was used to analyze these angles and their changes.And correlation analysis was used to analyze relationships between α angle change and other risk factors.Results:When compared with preoperative angles,the mean α angle,β angle,γ angle and δ angle were all significantly increased (p＜0.05) after the operation.The mean α angle and δ angle before the removal of internal fixation were both significantly smaller than those after the operation (p＜0.05),and the mean change ofα angle was-2.85 degrees.After the correlation analysis,we found significant correlations between the change ofα angle and postoperative correction curvature(-0.342,p=0.026),injured region in endplate(0.374,p=0.015),and change of the δ angle(0.231,p=0.041).Conclusion:There was significant loss in the correction curvature before the removal of internal fixation.And the loss was significantly associated with postoperative correction curvature,injured region in endplate,and change of the δ angle.

Objective: To evaluate the efficacy of postoperative radiotherapy in the treatment of parotid gland carcinoma. Methods: Eighty-six postoperated patients with parotid gland carcinoma( 7 in stage Ⅰ, 28 in stage Ⅱ, 33 in stage Ⅲ and 18 in stage Ⅳ) were radiated by 60Co ?-ray or linear accelerator X-ray combined with electron beam. All patients were diagnosed by pathology and followed up for more than 5 years. Results: The five year survival rate and the local control rate were 73.3% and 87.2% respectively. Poor prognosis was observed in the cases with the neoplastic classification of undifferentiated carcinoma, sequamous cell carcinoma and malignant pleomorphic adenoma, but the better prognosis was obtained in the cases with acinic cell carcinoma and mucoepidermoid carcinoma. Poor prognosis was observed in the cases with stage Ⅲ and Ⅳ of clinical stage. Radiotherapy undertaken in 2 weeks after surgical operation gave higher 5- year survival ratio( 83.8%). The group given 51～60 Gy radiation showed 82.9% of five- year survival rate. Conclusion: The combination of surgery with radiation is effective in the treatment of parotid gland carcinoma.Radiation of 51～60 Gy 2 weeks after operation may result in better prognosis. Neoplastic type and clinical stage are important factors for prognosis.

Sensory, chemical, microbiological quality and bacterial flora on fresh Pseudosciaena crocea were qualitatively and quantitatively investigated. The results showed that total viable counts and total volatile basic nitrogen reached 5. 51?0. 25Log10cfu/g, 7. 84?2. 25mg/100g respectively. 279 strains of bacteria were isolated and 84.2% of them were gram negative bacteria, a small percentages of gram positive bacteria were detected (6. 1% ) . The predominant bacterial floras were composed of Enterobacteriaceae (14. 7% ), Aeromonas spp. (12. 5% ), Acinetobacter spp. (11. 5% ) and Moraxella spp. (11. 1% ) . A few percent of Pseudomonas spp. , Stenotrophomonas maltophilia and other bacteria were also found. The high number of Enterobacteriaceae showed that bacterial contamination on Pseudosciaena crocea, was mainly from cultural water field and polluted seriously by non-borne bacteria, and it should be paid attention to.

Objective To evaluate the effects of small dose of antithymocyte globulin(ATG)and zenapax in the induction therapy for kidney transplant recipients.Methods A series of 150 cadaver-donor kidney transplant recipients were randomly divided to 3 groups,ie,small dose of ATG group(total dose,2.1 -3.0 mg/kg;n=72),zenapax group(50mg,on the first and 14th d after operation;n=15)and controls without induction therapy(n=63).Follow-up was 6 months.The rates of acute rejection,delayed graft func- tion(DGF)and pulmonary infection were statistically compared among the 3 groups.Results During a 6-month period,in ATG,zenapax and control groups,acute rejection episodes occurred in 4 cases(5.5%), 1(6.7%)and 10(15.9%),respectively;DGF occurred in 3(4.2%),0 and 8(12.7%),respectively;pul- monary infection occurred in 4(5.1%),1(6.7%)and 3(4.8%),respectively;leucocytopenia occurred in 3(4.2%),1(6.7%)and 5(7.9%),respectively;thrombocytopenia occurred in 2(2.8%),1(6.7%)and 5(7.9%),respectively.Conclusions In the early stage of kidney transplantation,small dose of ATG and zenapax can be the optimal choice for induction therapy.

Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P＜0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.

Objective:The current study investigated the effects of nesfatin-1 in the hypothalamic paraventricular nucleus (PVN) on gastric motility and the regulation of the lateral hypothalamic area (LHA).Methods:The projection of nerve ?ber and expression of nesfatin-1 were observed by retrograde tracing and fluo-immunohistochemistry staining;The nuclei microinjection and nuclei electrical stimulation,extracellular discharges of single unit neuron were used to observe the effects of nesfatin-1 on the GD neurons;Gastric motility recording in vivo were used to monitor the effects of nesfatin-1 on the amplitude of constriction and frequency of gastric motility in conscious rats.Results:Nesfatin-1 inhibited the majority of the GD-E neurons(1.97± 0.12 Hz vs.1.15± 0.07 Hz) and excited GD-I neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) in the PVN,which were weakened by oxytocin receptor antagonist H4928 (GD-E:1.38± 0.08 Hz,P＜0.05 vs.nesfatin-1;GD-I:2.49± 0.15 Hz,P＜0.05 vs.nesfatin-1).Gastric motility experiments showed that administration ofnesfatin-1 in the PVN decreased gastric motility.Retrograde tracing and immunofluorescent staining showed that nucleobindin-2/nesfatin-1 and fluorogold double-labeled neurons were observed in the LHA.Electrical LHA stimulation excited the firing rate of GD-responsive neurons (GD-E:2.06± 0.12 Hz vs.4.23± 0.21 Hz,GD-I:1.61± 0.09 Hz vs.4.83± 0.25 Hz) in the PVN.Pre-administration of an antinucleobindin-2/nesfatin-1 antibody in the PVN strengthened gastric motility,decreased GD-E neurons (1.74± 0.10 Hz vs.3.04± 0.18 Hz) and excited the discharging of the GD-I neurons(4.15± 0.18 Hz vs.4.83± 0.25) induced by electrical stimulation of the LHA.Conclusion:Nesfatin-1 in the PVN could serve as an inhibitory factor to inhibit gastric motility,which might be regulated by the LHA.

BACKGROUND: Acute kidney injury (AKI) is associated with a high mortality. This study was undertaken to detect the factors associated with the prognosis of AKI. METHODS: We retrospectively reviewed 98 patients with AKI treated from March 2008 to August 2009 at this hospital. In these patients, 60 were male and 38 female. Their age ranged from 19 to 89 years (mean 52.4±16.1 years). The excluded patients were those who died within 24 hours after admission to ICU or those who had a history of chronic kidney disease or incomplete data. After 60 days of treatment, the patients were divided into a survival group and a death group. Clinical data including gender, age, history of chronic diseases, the worst laboratory values within 24 hours after diagnosis (values of routine blood tests, blood gas analysis, liver and renal function, levels of serum cystatin C, and blood electrolytes) were analyzed. Acute physiology, chronic health evaluation (APACHE) II scores and 60-day mortality were calculated. Univariate analysis was performed to find variables relevant to prognosis, odds ratio (OR) and 95％ confidence interval (CI). Multiple-factor analysis with logistic regression analysis was made to analyze the correlation between risk factors and mortality. RESULTS: The 60-day mortality was 34.7％ (34/98). The APACHE II score of the death group was higher than that of the survival group (17.4±4.3 vs. 14.2±4.8, P<0.05). The mortality of the patients with a high level of cystatin C>1.3 mg/L was higher than that of the patients with a low level of cystatin C (<1.3 mg/L) (50％ vs. 20％, P<0.05). The univariate analysis indicated that organ failures≥2, oliguria, APACHE II>15 scores, cystatin C>1.3 mg/L, cystatin C>1.3 mg/L+APACHE II>15 scores were the risk factors of AKI. Logistic regression analysis, however, showed that organ failures≥2, oliguria, cystatin C>1.3 mg/L +APACHE II>15 scores were the independent risk factors of AKI. CONCLUSION: Cystatin C>1.3 mg/L+APACHE II>15 scores is useful in predicting adverse clinical outcomes in patients with AKI.

ABSTRACT:Objective To investigate the effect of SDF-1/CXCR7 on inflammatory cytokine synthesis and secretion in gastric cancer SGC-7901 cells.Methods CXCR7 gene in SGC-7901 cells was silenced by shRNA lentiviral vector and the expression of CXCR7 was detected using Western blot and Real-time PCR.There were four groups as follows:LV-shRNA-NC,LV-shRNA-NC+SDF-1,LV-shRNA-CXCR7,and LV-shRNA-CXCR7+SDF-1 groups.Real-time PCR was used to detect the mRNA expressions of TNF-α,IL-1β,IL-6 and IL-8.ELISA was used to detect the protein levels of TNF-α,IL-1β,IL-6 and IL-8 in the culture supernatant.Western blot was used to detect the protein expressions of NF-κB pathway.Results ① Transfection of SGC-7901 cells with CXCR7-shRNA lentiviral vector resulted in a significantly decreased expression of CXCR7 at both mRNA and protein levels (all P<0.01).② Compared with those in LV-shRNA-NC group,IL-6 and IL-8 mRNA expressions and protein levels in the culture supernatant were increased in LV-shRNA-NC+SDF-1 group (P<0.01 )and decreased in LV-shRNA-CXCR7 group (P<0.05).Compared with those in LV-shRNA-NC+SDF-1 group,the expressions of IL-6 and IL-8 at mRNA and protein levels in the culture supernatant were significantly cut down in LV-shRNA-CXCR7+SDF-1 group (P<0.01 ).However,the expressions of TNF-αand IL-1βat mRNA and protein levels in the culture supernatant were not significantly changed by SDF-1 and CXCR7 shRNA.③ The protein expressions of nuclear NF-κB p65,t-IκBαand p-IκBαexhibited no significant differences among the four groups.Conclusion SDF-1/CXCR7 can promote the synthesis and secretion of inflammatory cytokines IL-6 and IL-8 in gastric cancer SGC-7 9 0 1 cells through an NF-κB-independent pathway.
