OBJECTIVETo compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.

METHODSFrom January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.

RESULTSThe loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).

CONCLUSIONLumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.

This paper mainly discussed a bacterial stain with high flocculating activity isolated from cantaloupe juice .The strain was named Bacillus sp.B_(53) based on colony morphology, physiological and biochemistry experiments. The new flocculant was purified and shown to be a homopolymer of glutamic acid by HLPC analysis and thin layer chromatography, and presumed to be Poly ?-glutamic acid(?-PGA). ?-PGA 12.48g/L was achieved in shake flask. The purified material showed a absorption peak at 212nm, and was only composed of L-Glu. The MW could be detected through SDS-PAGE, and its MW was about a molecular mass between 440kD with 669kD. This bioflocculant efficiently flocculated various organic and inorganic suspensions. It's flocculanting effect on kaolin and ([BF]Ca(OH)_2[BFQ]) was superior to others.

The cerebral blood flow of infant is effected by physiological and pathological factors.As the cerebrovascular autoregulation of neonates is poor,in pathological cases,especially when hypoxemia and hypercapnia impaired regulation of its own,lead to changes in cerebral blood flow,then resulting in severe brain injury.It has made enormous progress in the research on the changes of cerebral blood flow in newborns in recent years.In normal infants,cerebral blood flow velocities is positively correlated to gestational age and body weight,and increase gradually with day-age in the first week after birth.The cerebral blood flow of newborn with brain injury can present as insufficiency,over-perfusion or low speed high-resistance earlier and high speed low-resistance later.Different results may be related to the duration and severity of asphyxia,but all of those are signs of damage of self-regulatory function of cerebral blood flow.Cerebral hemodynamic change is the important pathogenesis mechanism of brain injury.

Objective To investigate the current dyslipidemia profiles and correlation with etiological factors in early stage post-transplantation, and the impact of lipid metabolic disorder on renal function. Methods The clinical data of 1032 renal allografts from eight hospitals in Beijing between 2004 and 2008 were collected and evaluated retrospectively. Before and at the 1st, 3rd, 6th and 12th month post-transplantation, the changes in blood total cholesterol (TC), triglycerides (TG),low density lipoprotein (LDL)-cholesterol and high density lipoprotein (HDL)-cholesterol were analyzed. The difference in the blood lipid disorder at different stages stratified by time and different age group, the effects of immunosuppressive agents on blood lipid, and the impact of blood lipid disorder on the blood creatinine were studied. Results Except HDL-cholesterol, TC, LDL-cholesterol and TG levels were increased gradually at the first year, especially LDL-cholesterol and TG. The TC and LDL-choleaterol abnormalities were obviously related with age (P<0. 01 ). The effect of Tacrolimus (Tac)-based immunosuppressive regimen on the lipid metabolic disorder was less than cyclosporine (CsA). At the first year, there was no significant difference in blood creatinine between lipid-lowering treatment and non-lipid-lowering treatment (P>0. 05). For the recipients not subject to lipid-lowering treatment and their TG level higher than the normal at the first month after operation, the creatinine level at the first year was significantly higher than in those with normal TG level (P< 0. 05). Conclusion The lipid metabolic disorder following renal transplantation is a common complication after the first transplant year, and was related with age and immunosuppressive agent regimen. Tac-based immunosuppressive regimen has little effects on the blood lipid metabolism.

Objective:To evaluate the efficacy of remimazolam-propofol-sufentanil for anesthesia in patients undergoing painless gastroscopy.Methods:Eighty American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 20-59 yr, weighing 44-69 kg, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=40 each) using a random number table method: remimazolam-propofol-sufentanil group (group RPS) and propofol-sufentanil group (group PS). The patients in group RPS received successive intravenous injection of sufentanil 0.1 μg/kg, remimazolam 0.15 mg/kg and propofol (at a rate of 4 mg/s). The patients in group PS received intravenous injection of sufentanil 0.1 μg/kg and propofol (at a rate of 4 mg/s). When Observer′ s Assessment of Alertness/Sedation Scale score was 0, gastroscopy was performed.The consumption of propofol, time of anesthesia, time for gastroscopy, emergence time and discharge time were recorded.The number of intraoperative assisted respiration cases, body movement and occurrence of adverse reactions at the time of discharge were observed. Results:Compared with group PS, the consumption of propofol was significantly decreased, and the time of anesthesia, emergence time and discharge time were shortened in group RPS ( P<0.05). There was no significant difference in the time for gastroscopy, the number of intraoperative assisted respiration cases, body movement and the occurrence of adverse reactions at discharge time between the 2 groups ( P>0.05). Conclusion:Remimazolam-propofol-sufentanil produces better efficacy for anesthesia than propofol-sufentanil in patients undergoing painless gastroscopy.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.

METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.

RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).

CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.

OBJECTIVETo study the effect of acupuncture on the immune function of sepsis patients.

METHODSNinety sepsis patients were assigned to the control group, the thymosin a1 group, and the acupuncture treatment group according to random digit table, 30 patients in each group. Patients in the control group were treated according to the guideline of Surviving Sepsis Campaign (SSC). Patients in the control group received routine treatment. Those in the thymosin alpha1 group additionally received subdermal injection of thymosin alpha1 (1.6 mg), once per day for 6 successive days. Needling at related points such as Zusanli (ST36), Yanglingquan (GB34), Neiguan (PC6), Guanyuan (RN4), and so on, was performed in patients of the acupuncture treatment group, once per day for 6 successive days. T cell subgroups (CD3+, CD4+, CD8+, CD4+ /CD8+) and immunoglobulin levels (IgG, IgA, IgM) were detected. The length of ICU hospital stay, hospital readmission rate, and 28-day mortality were compared among the three groups.

RESULTSAfter six days of treatment, CD3+, CD4+, CD8+, IgG, IgA, IgM, and CD4+ /CD8+ ratio of three groups were all significantly increased (P < 0.01). Of them, CD3+, CD4+, CD8+, IgG, IgA, and IgM increased more significantly in the thymosin alpha1 group and the acupuncture treatment group (P < 0.01). Compared with the control group, the ICU hospitalization length was significantly shortened, the hospital readmission rate and the 28-day mortality were lower in the thymosin alpha1 group and the acupuncture treatment group (P < 0.05, P < 0.01). There was no statistical difference in each index between the thymosin alpha1 group and the acupuncture treatment group (P > 0.05).

CONCLUSIONAcupuncture could adjust the immune function of sepsis patients, improve their immunological indicators and prognoses.
