OBJECTIVETo investigate the apoptosis and proliferation effect of matrine on human medulloblastoma cell line D341 in vitro and the effect of the expression of the related caspase 3 and caspase 9 proteins.

METHODSThe D341 cells were cultivated successfully in vitro. Then the cells were divided into 5 groups according to the concentration of matrine (0.5 mg/mI group, 1.0 mg/ml group, 1.5 mg/ml group, 2.0 mg/ml group and the control group was 0 mg/ml). All the experiments were repeated three times. The cell morphologic and structure change was observed with the optical microscope and the transmission electron microscope. The proliferation of D341 cell was analyzed using Cell Counting Kit-8 assay. Apoptosis was detected by Annexin V-FITC/PI double staining. The expression of Caspase3 and Caspase9 was detected by Western blot.

RESULTSWith the effect of matrine, the proliferation inhibition rate gradually increased with drug concentrations increasing, and there was a significant difference (P < 0.01). The inhibitory effect of matrine on cell proliferation was different with the different treatment time, there was a significant difference between the 24 h to 72 h groups (P < 0.01). The apoptotic rate increased with matrine concentrations increasing. There were significant differences between the group of 0.5 mg/mI or 1.0 mg/mI to the group of 1.5 mg/mI or 2.0 mg/mI (P < 0.05). The apoptotic rate increased with the prolonged treatment time. There were significant differences between the group of 24 h or 48 h to the group of 72 h ( P < 0.05). With the increase of matrine concentration, the expression of Caspase 3 and Caspase 9 increased (P < 0.01).

CONCLUSIONMatrine induces the apoptosis, and inhibits the proliferation of human medulloblastoma D341 cells in vitro by up-regulation of the expression level of Caspase3, Caspase9.

Objective To investigate activated nano carbon in prophylactic central lymph node dissection of T1 papillary thyroid non-microcarcinoma.Methods Patients with T1 papillary thyroid non-microcarcinoma in Thyroid Surgery Department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University undergoing surgery from Jan.2012 to Jun.2013 were divided into 2 groups:odd numbers were the experimental group,and even numbers were the control group.Activated nano carbon was injected in the affected side of the thyroid in the experimental group.The lymph node metastasis,parathyroid function,and the rate of recurrent laryngeal nerve (RLN) injury were compared between the 2 groups.Results The total number of resected lymph nodes in the experimental group and the control group were 327 and 238 respectively.The positive lymph nodes in the experimental group and the control group were 120 (36.7％)and 56 (23.5 ％)respectively.The difference had statistical significance (P =0.000 85).The number of patients with lymphatic metastasis in the experimental group and the control group was 42 (56％) and 30 (40％) respectively.The difference had statistical significance (P =0.049 9).The average number of positive lymph node for patients in the experimental group and the control group was (2.86 ± 0.13) and(1.87 ± 0.09) respectively.The difference had statistical significance(P =0.009).The rate of transient hypoparathyroidism in the experimental group and the control group was 34.7％ and 60％ respectively.The difference had statistical significance (P =0.002).The incidence of hoarseness caused by RLN injury was 2.7％ and 4％ respectively in the experimental group and the control group.The difference had no statistical significance(P =1.000).Conclusions Activated nano carbon plays an important role in prophylactic central lymph node dissection of T1 papillary thyroid non-microcarcinoma phase.It not only contributes to lymph node dissection,but also protects parathyroid.However,it can't reduce the incidence of RLN injury.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

Objective: To investigate the effect and mechanism of helix B surface peptide (HBSP) on myocardial ischemia reperfusion injury (MIRI) in experimental mice.
Methods: The MIRI model was established by ligation of anterior descending coronary artery of the mice for 45 min and followed by corresponding treatment at 5 min before reperfusion. A total of 64 male ICR mice were randomly assigned to 4 group:①Sham group,②MIRI group, the mice received normal saline at 5 min before reperfusion,③HBSP group, MIRI mice received HBSP at 5 min before reperfusion and④HBSP+PD98059 group, MIRI mice received PD98059 (a speciifc blocker of ERK1/2) at 20 min before reperfusion and followed by HBSP at 5 min before reperfusion.n=16 in each group, all animals were treated for 2 hours. The area of myocardial infarction (MI) was detected by TTC-EB double staining method, the myocardial apoptosis rate was examined by TUNEL method, the levels of protein expression of ERK1/2 and phosphorylation of ERK1/2 were measured by Western blot analysis.
Results: Compared with MIRI group, HBSP group presented decreased MI area, decreased myocardial apoptosis rate and increased phopsphorylation level of ERK1/2, allP<0.05. Compared with HBSP group, HBSP+PD98059 group showed decreased phopsphorylation level of ERK1/2, increased myocardial apoptosis rate and increased MI area, allP<0.05.
Conclusion: HBSP may reduce the MI area via inhibiting myocardial apoptosis and therefore, protecting the experimental mice from MIRI; the mechanism might be related to the activation of ERK1/2 pathway.

Objective: To investigate the clinical efficacy of minimally invasive plate oseoynthesis (MIPO) assisted by a self-designed lower limb axial tractor in the treatment of complex tibial plateau fractures. Methods: The data were retrospectively analyzed of the 31 patients who had undergone surgical treatment for complex tibial plateau fractures from June 2015 to April 2018 at Department of Orthopeadics, Hospital Affiliated to Binzhou Medical College. MIPO was conducted with the assistance of the axial tractor in 17 of them. They were 12 men and 5 women with an age of 50.8±14.7 years, with 8 cases of Schatzker type Ⅴ and 9 ones of Schatzker type Ⅵ. MIPO was conducted without the assistance of the axial tractor but with the assistance of manipulation reduction in the other 14 patients. They were 9 men and 5 women with an age of 48.9±9.5 years, with 6 cases of Schatzker type Ⅴ and 8 ones of Schatzker type Ⅵ. The 2 groups were compared in terms of operation time, intraoperative bleeding, and Rasmussen scores for knee function and medial angle of the proximal tibia at the last follow-up. Results: The 2 groups were comparable due to insignificant differences in the preoperative general data between them (P>0.05). The tractor and manipulation groups were followed up for a mean of 9.8 months and 10.9 months respectively. Bone healing was achieved in all patients. For the tractor and manipulation groups, respectively, the operation time was127.8±40.8 min and 174.1±66.8 min, and the intraoperative bleeding 115.6±41.7 mL and 184.3±91.4 mL, showing significant differences between them (P<0.05). In the tractor group at the last follow-up, the knee flexion was 126.1°±9.3°, the medial angle of the proximal tibial 87.8°±1.4°, the posterior inclination angle 8.7°±3.8° and the Rasmussen score 26.5±2.9 points; in the manipulation group at the final follow-up, the knee flexion was 124.7°±8.9°, the medial angle of the proximal tibial 86.9°±2.1°, the posterior inclination angle 9.8°±4.1° and the Rasmussen score 25.6±3.2 points. There were no significant differences between the 2 groups in the above items (P>0.05). Loss of force line was observed in none of the patients at the last follow-up. Conclusion Compared with conventional manipulation reduction, use of our self-designed lower limb axial tractor can shorten operation time, reduce bleeding and facilitate reduction of fracture fragments in the treatment of tibial plateau fractures of Schatzker types Ⅴ and Ⅵ.

OBJECTIVETo analyze the magnetic resonance imaging (MRI) findings of radiation-induced liver injury following three-dimensional conformal radiotherapy.

METHODSA retrospective review of the MRI data was conducted in 20 patients treated between September 2000 and October 2005, who suffered liver injuries induced by 1 or 2 three-dimensional conformal radiotherapy sessions for liver neoplasm. The patients underwent MR scans with T2-weighted sequences and T1-weighted sequences in both plain and Gd-DTPA enhanced MRI. Four patients with suspected tumor relapse suggested by MRI were pathologically confirmed to have radiation-induced liver injury.

RESULTSAcute radiation-induced liver injury was represented by large patches of liver edema consistent with the irradiation volume, showing low signal intensity on T1-weighted images (T1WI) and high signal intensity on T2-weighted images (T2WI) without arterial phase enhancement after Gd-DTPA injection. Delayed radiation-induced liver injury was manifested by slightly low-intensity signal on plain T1WI and slightly high-intensity signal on T2WI without obvious arterial phase enhancement following Gd-DTPA injection but with marked enhancement during the portal-venous and delayed phases.

CONCLUSIONRadiation-induced liver injury presents characteristic MRI features, and plain and dynamic enhanced MRI can be of great value for its diagnosis.

OBJECTIVETo assess the therapeutic effect of losartan on type 2 diabetes mellitus (DM2) with gas chromatography (GC)-based metabonomics.

METHODSDM2 patients were dosed with losartan (100 mg/d) and urines were collected at week 8 and 12. The biochemical criteria (blood pressure, urinary albumen, urinary 8-hydroxy-2'-deoxyguanosine and blood creatinine) were analyzed. Urine samples were derivatived and analyzed by GC. Multivariate metabonomics analysis was performed after peak alignment.

RESULTSAfter 8-12 weeks, losartan showed little curative effect and no remarked changes of biochemical criteria were observed. However, metabonomics analysis revealed that some biomarkers such as glucitol and inositol changed.

CONCLUSIONGC-based metabonomics analysis enables the rapid identification of metabolic differences and provides information concerning therapeutic effect of losartan.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

OBJECTIVETo explore the surgical strategy for ectopic kidney and evaluate the clinical outcomes.

METHODSFrom January 2000 to October 2009, 35 cases of ectopic kidney were treated surgically in our hospital. Definite diagnoses were established in all the cases by ultrasound, intravenous urography (IVU), cystoscope, CT, magnetic resonance urography (MRU) and radionuclide imaging before the surgery. In these patients, 26 had ipsilateral ectopic ureteral orifice (including 5 with bilateral duplicated kidneys and ureter), 9 had moderate or severe hydronephrosis (including 3 with ectopic kidney calculi), and 24 had dysplastic kidney (24/35). All the patients underwent operations, including 26 with ectopic nephrectomy, 7 with ectopic ureterovesical reimplantation, and 3 with ectopic renal pelvis incision.

RESULTSThe clinical effect was satisfactory in all the cases during the follow up of 7 to 29 months.

CONCLUSIONAppropriate surgical approaches according to the concurrent deformities and complications can achieve good clinical results in patients with ectopic kidneys.

OBJECTIVE: To investigate the feasibility and safety of substituting tacrolimus(FK506) for cyclosporin A(CsA) on delaying the pace of renal dysfunction in patients with biopsy-proven chronic allograft nephropathy(CAN). METHODS: Seventy-three renal transplantation patients with CAN proved by allograft biopsy were collected in this study. Patients were randomly divided into 2 groups. Patients were either converted to FK506(FK506 group, n=43) or remained on their initial CsA-based immunosuppression(CsA group, n=30). The clinical data at study entry and after 12 months including blood urea nitrogen(BUN), serum creatinine(SCr), glomerular filtration rate(GFR), 24-hour urine protein excretion, serum total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and the side effects of calcineurin inhibitors were monitored during a follow-up of over 12 months. RESULTS: Twelve months later, the level of SCr was statistically reduced and GFR levels were obviously elevated in the FK506 group as compared with CsA group [(194.8+/-42.5)micromol/L vs. (245.4+/-52.8)micromol/L and (50.14+/-3.92)mL/(min.1.73 m(2)) vs. (40.58+/-2.49)mL/(min.1.73 m2), P<0.01]. Quantity of 24-hour urine protein excretion in the FK506 group was (2.0+/-0.5)g which is significantly lower than (3.9+/-0.7)g in the CsA group(P<0.01). TC, TG, and LDL levels remained unchanged in the CsA group, while those were statistically reduced in the FK506 group respectively [(5.19+/-0.73)mmol/L vs. (6.94+/-1.37)mmol/L, (1.86+/-0.84)mmol/L vs. (3.14+/-1.38)mmol/L, (3.03+/-0.71)mmol/L vs. (3.82+/-0.89)mmol/L, P<0.01]. Tremor obviously increased (P<0.01) and hypertension obviously decreased (P<0.05) in the FK506 group compared with the CsA group. CONCLUSION FK506 treatment can greatly improve the proteinuria and hyperlipidemia. Conversion from CsA to FK506 is an effective and safe alternative therapy for delaying the progression of renal dysfunction induced by CAN.
