A HPLC method was established to determine the contents of the five anthraquinones and rhaponticin in the different varieties of Rhei Radix et Rhizoma. The difference existed in different varieties. The results showed that rhein and rhaponticin were marker substances which could be used to distinguish palm leaf groups rhubarb and wave leaf groups rhubarb. Authentic rhubarb didn't contain rhaponticin. Falsify rhubarb contains trace amounts of rhein. Rheum tanguticum contains abundant rhein. The ratio value of the content of rhein to chrysophanol could be used to distinguish R. tanguticum from the other two authentic varieties (R. palmatum and R. officinale). The content of rhaponticin varied largely in different varieties of wave leaf groups rhubarb.

OBJECTIVETo assess the efficacy and safety of Tangzu Yuyang Ointment (TYO) for treatment of chronic diabetic foot ulcers.

METHODSFifty-seven patients with chronic diabetic foot ulcers of Wagner's ulcer grade 1 to 3 were randomly assigned to the control group (29 cases) and the treatment group (28 cases). Patients in the control group received the standard wound therapy (SWT), while those in the treatment group received SWT plus TYO. The ulcer healing rate, the ulcer improvement rate and the incidence of adverse events were compared between the two groups. Totally 48 patients finished the final follow-ups and entered the data analysis.

RESULTSThe ulcer improvement rate was 79.2% in the TYO group and 41.7% in the SWT group (P=0.017) at the 12th week, and 91.7% vs. 62.5% (P=0.036) at the 24th week. There was no statistical difference in the ulcer healing rate and the incidence of adverse events between the two groups at week 4, 12, and 24, respectively. The ulcer healing time was 96 +/- 56 days in the TYO group and 75 +/- 53 days in the SWT group, showing insignificant difference (P=0.271).

CONCLUSIONTYO plus SWT was more safe and effective than SWT alone in the treatment of chronic diabetic foot ulcers.

In order to explore the influence of purified donor regulatory T cells (T(Reg) cells) infused after allogeneic bone marrow transplantation (allo-BMT) on GVHD and hematopoietic reconstitution of mice, an allo-BMT model of C(57)BL/6-->BALB/c mice was established. CD4(+)CD25(+)T(Reg) cells were purified through bead-magnetic activated cells separated from donor mice peripheral blood. The recipient mice were randomly divided into three groups: CD4(+)CD25(+) T cells, CD4(+)CD25(-) T cells and RPMI 1640 culture medium. These cells and RPMI 1640 were infused into recipient mice by caudal veins at about 6 to 8 hours after allo-BMT respectively. Incidence of GVHD, pathological lesion of liver, spleen, small intestine, survival time and hematopoietic reconstitution in the recipients were observed after allo-BMT. The results showed that the time for WBC > 1.0 x 10(9)/L was (8.14 +/- 3.26) days, (17.62 +/- 5.71) days, (19.81 +/- 6.77) days and the time for Plt > 20.0 x 10(9)/L was (5.29 +/- 1.34) days, (8.97 +/- 3.44) days, (9.52 +/- 3.92) days in T(Reg) positive cell group, T(Reg) negative cell group and the blank control group respectively, and the recovery times of WBC and Plt in T(Reg) positive cell group were faster than that in T(Reg) negative cell group and the blank control group (P < 0.05). The scores of GVHD were (1.33 +/- 0.58), (1.80 +/- 0.27), (1.93 +/- 0.45) in three groups of mice at about 15 days after allo-BMT, respectively, the GVHD in T(Reg) positive cell group was slighter than that in T(Reg) negative cell group and the blank control group (P < 0.05). It was found that GVHD pathologic manifestations of the liver, spleen and small intestine in T(Reg) positive cell group were slighter in a certain extent than those in other two groups at about (25 - 30) days after allo-BMT. The mean survival time in three groups was (41.45 +/- 17.88) days, (18.75 +/- 14.39) days and (25.67 +/- 16.84) days after allo-BMT, respectively, which in the T(Reg) positive cell group was significantly longer than that in other two groups (P < 0.05). It is concluded that donor-T(Reg) cell infusion can mitigate the GVHD so as to reach hematopoietic reconstitution and prolong survival time after allo-BMT in mice.

BACKGROUNDSpinal anesthesia is considered as a reasonable anesthetic option in lower abdominal and lower limb surgery. This study was to determine the dose-response of intrathecal ropivacaine in patients with scarred uterus undergoing cesarean delivery under combined spinal-epidural anesthesia.

METHODSSeventy-five patients with scarred uterus undergoing elective cesarean delivery under combined spinal-epidural anesthesia were enrolled in this randomized, double-blinded, dose-ranging study. Patients received 6, 8, 10, 12, or 14 mg intrathecal hyperbaric ropivacaine with 5 μg sufentanil. Successful spinal anesthesia was defined as a T4sensory level achieved with no need for epidural supplementation. The 50% effective dose (ED50) and 95% effective dose (ED95) were calculated with a logistic regression model.

RESULTSED50and ED95of intrathecal hyperbaric ropivacaine for patients with scarred uterus undergoing cesarean delivery under combined spinal-epidural anesthesia (CSEA) were 8.28 mg (95% confidence interval [CI]: 2.28-9.83 mg) and 12.24 mg (95% CI: 10.53-21.88 mg), respectively.

CONCLUSIONWhen a CSEA technique is to use in patients with scarred uterus for an elective cesarean delivery, the ED50and ED95of intrathecal hyperbaric ropivacaine along with 5 μg sufentanil were 8.28 mg and 12.24 mg, respectively. In addition, this local anesthetic is unsuitable for emergent cesarean delivery, but it has advantages for ambulatory patients.

Objective To investigate the effect of basic fibroblast growth factor(bFGF)by intraventricular injection on traumatic brain injury(TBI)in rats. Methods Twenty-four adult SD rats were randomly divided into treatment group and control group.TBI model was established by modified Feeneg's method.The treatment group and the control group were intraventricularly injected bFGF and saline 24 h after TBI, respectively.The recovery of limb function was observed by behavior tests (forelimb placing test and beam balance test). After labeling the neural stem cells with bromodeoxyuridine(Brdu),immunohistochemical staining,was employed to measure and compare the expression of Brdu-positive cells in the lateral subventricular zone(SVZ),the dentate gyrus of the hippocampus and the damage region at 3,7 and 14 d after TBI. Results The grading of forelimb placing test and beam balance test in the 2 groups was significantly different:in the forelimb placing test,statistical significance was found from the 3rd to the 12th d(P<0.05);in the beam balance test,statistical significance was found from the 3rd to the 11th d(P<0.05).Compare with the control group,treatment group showed significantly increased number of Brdu-positive ceils in the bilateral SVZ,the dentate gyrus of the hippocampus and the damage region after TBI(P<0.05).The number of Brdu-positive cells on the damage side was significantly higher than that on the opposite side (P<0.05).The grading of behavior test was negatively correlated to the number of Brdu-positive cells.Conclusions Intraventricular injection of bFGF can increase the proliferation of endogenous neural stem cells and speed up the recovery of limb function in TBI model of rats.dogenous neural stem cells and expidite the restoration of limbs function in the ratmodel of TBI.

OBJECTIVETo study the pathologic features, differential diagnosis and role of open lung biopsies (OLB) in usual interstitial pneumonia (UIP).

METHODThe authors reviewed the pathologic, clinical and radiologic features of five cases of UIP (one autopsy case and four OLB cases), with follow-up information.

RESULTSThe typical histologic features were a non-uniform distribution of alveolar inflammation, fibroblastic foci, interstitial fibrosis and honeycomb change. There also was associated metaplasia of bronchiolar epithelium, type II pneumocyte hyperplasia and accumulation of alveolar macrophages.

CONCLUSIONSCharacteristically, UIP exhibits temporal heterogeneity under low-power light microscopy, which includes changes in both the early and end stages. Open lung biopsy is an important diagnostic adjunct for suitable patients with atypical radiologic features on computerized tomography. Correlation between clinical, radiologic and pathologic findings is also essential for a correct diagnosis.

OBJECTIVETo analyze the incidence and the risk factors of late-onset non-infectious pulmonary complications (LONIPC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSClinical data from 144 patients who underwent allo-HSCT and survived more than 3 months at our institution between January 2003 and August 2006 were collected, and the incidence and its risk factors of LONIPC were reviewed retrospectively.

RESULTSWith a median follow-up time of 1149 (103 - 2151) d, 24 patients (16.7%) fulfilled the diagnostic criteria for LONIPC. The median time to diagnosis of LONIPC was 235 days after transplantation (range, 116 - 950 days). Three variables were associated with LONIPC on univariate analysis: CMV antigenaemia (P = 0.000), grade II-IV aGVHD (P = 0.026) and cGVHD (P = 0.002). By using a Binary Logistic regression model for multivariate analysis, cGVHD (OR = 18.804, P = 0.004) and CMV antigenaemia (OR = 14.376, P = 0.000) were the risk factors of LONIPC.

CONCLUSIONLONIPC is one of the major complications after allo-HSCT and cGVHD and CMV antigenaemia are the risk factors for developing LONIPC.
