Objective To evaluate the clinical efficacy in the treatment of unilateral micrognath ia by using EAM medical resin and hydroxyapatite (EH) composite material combined with the CAD/ CAM technique.Methods From July 2011 to October 2015,12 cases of unilateral micrognathia caused by different reasons were treated,based on the representative traits and requirements,refering to the unsymmetric counter part by right of CAD/CAM technique.By the 3-dimensional design and reconstruction,we reformed the EH composite material into purposed shape,and insert it in the operative area.Results All the materials were closely suitable to the mandible surfaces.1 case failed because the wound was torn apart;the other 11 patients recovered more than 6 months and were satisfied with the external appearance.Conclusions The EH composite materials combined with CAD/ CAM techniques could be a potential characterized remedy for the unilateral micrognathia.

Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

Objective: To establish an HPLC-fluorescence detection method for the determination of thioguanosine-monophosphate (TGMP), thioguanosine-diphosphate (TGDP) and thioguanosine-triphosphate (TGTP) in red blood cells (RBC), as well as quantify the individual thioguanine nucleotides metabolites in kidney transplant recipients with azathioprine (AZA) therapy.Methods: The individual thioguanosine phosphates were extracted from RBC by dichloromethane and subsequently oxidized by potassium permanganate.The separation was achieved on a Nucleosil C18 column (150 mm×4.6 mm,5 μm) with an ion pairing reagent and detected by a fluorescence detector (excitation at 315 nm, emission at 390 nm).The mobile phase consisted of 20 mmol·L-1 potassium phosphate buffer (pH was adjusted to 6.8 by 5 mmol·L-1 tetrabutylammonium hydrogensulfate)-acetonitril (80:20) with the flow rate of 1.0 ml·min-1.Results: TGMP, TGDP and TGTP were quantified from RBC within the range of 50-500, 50-1000 and 100-5 000 pmol·ml-1, respectively.The limit of quantification (LOQ) was 50, 50 and 100 pmol·ml-1 RBC for TGMP, TGDP and TGTP, respectively.The intra-and inter-day RSDs were below 7.0% with the method recovery between 95.0% and 103.6%.The mean extraction recovery was above 90%.The assay was applied in the blood samples of 30 kidney transplant recipients with AZA therapy, and the results indicated that TGTP was the predominant phosphate metabolite in RBC.Conclusion: The method is simple, rapid, sensitive and specific, and it can quantitatively determine the individual thioguanosine phosphates in RBC of kidney transplant recipients with AZA therapy.

Objective To investigate the expression and clinical significance of T-cell receptor (TCR) Ⅴβ subfamily in hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF) patients.Methods Twenty-eight patients with HBV-ACLF (HBV-ACLF group) and 32 patients with chronic hepatitis B flare (CHB-F group),who were treated in The Second People's Hospital from Oct.2010 to Mar.2012,and 20 healthy controls (HC group) were included in the study.Reverse transcriptase-polymerase chain reaction was used to detect the levels of TCR Ⅴβ subfamily and enzymelinked immunosorbent assay was used to detect the levels of serum cytokines [interleukin (IL)-2,IL-4,IL-6,IL-10,interferon (IFN)-γ and tumor necrosis factor (TNF)-α)] in the three groups.The comparison among three groups was done by one-way analysis of variance and the comparison between two groups was done by LSD-t test or rank sum test.Results The three groups had similar gender and age distribution (all P＞0.05).The HBV-ACLF group had significant different profiles of total bilirubin,albumin,prothrombin activity,international normalized ratio and cholesterol tatol compared with the CHB-F group (all P＜0.05).For patients in the HBV-ACLF group,the serum IL-2,IL-4,and IL-10 levels were lower(all P=0.000),and the IL-6 and IFN γ levels were higher than those of the HC group (all P=0.000).The IL-4,IL-10,and TNF-α levels in the CHB-F group were also significantly lower than those of the HC group (all P=0.000).Compared with the CHB-F group,the HBV-ACLF group had significantly lower IL-2,IL-10,and TNF-α levels (P=0.003,0.002,0.004),and higher IL-6 and IFN-γ levels (P=0.015,0.006).By one-way analysis of variance,there were significantly differences of △Ct1,△Ct5,△Ct7,△Ct12,△Ct15,△Ct20,△Ct22,and △Ct23 among the three groups (H=20.368,14.368,19.500,31.532,19.985,19.116,41.752 and 20.649,all P＜0.05).Conclusion The expression levels of TCR Ⅴβ subfamily and cytokines are changed in HBV-ACLF patients.

Methods　Volume-overload cardiac hypertrophy of rat was induced by aortocaval shunts. The rats were given ig TFM (400, 40 and 4 mg/kg/d). c-Fos protein in the ventricles were measured by immunocytochemical study. Results　TFM at the above dosage decreased heart weight and contents of RNA and protein in the myocardium, inhibited the expression of c-Fos protein in the ventricles. Conclusion　TFM can prevent volume-overload cardiac hypertrophy in rats. The inhibitory effects on the expression of c-Fos protein may be its mechanism in the molecular level.

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.

METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.

RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.

CONCLUSIONShugan Yiyang Capsules can be used for the treatment of asthenospermia, and its effect can be enhanced in combination with oral levocarnitine.

Objective To discuss the technique of Neuroform stent-assisted coil embolization for the treatment of intracranial wide-necked aneurysms and to evaluate its clinical efficacy and complications.Methods Neuroform stent-assisted technique was used for coil embolization treatment in 31 patients with intracranial wide-necked aneurysms, all aneurysms were ruptured and the patients suffered from subarachnoid hemorrhage (SAH). Of the total 43 aneurysms, 39 were wide-necked and 4 were narrow-necked. Results Thirty-five stents were inserted in 31 patients. The stents were implanted in both internal carotid arteries in 3 patients and in both middle cerebral arteries in one patient, Intra-arterial embolization with coils was successfully performed in 41 of 43 aneurysms. Intraoperative hemorrhage occurred in 2 patients, which probably resulted from the rupture of middle cerebral artery branch due to microwire damage. The cerebral isehemic symptom happened in 1 patient with posterior communicating artery aneurysm due to the shifting of the coil from the original site to M2 segment of middle cerebral artery. During a follow-up period of 24.7 months in average, neither death nor recurrent hemorrhage occurred in 29 cases. Twenty-eight patients were in good living condition and the remaining one patient showed obvious disturbance of neural function.Conclusion For the treatment of intracranial wide-necked aneurysms, intra-arterial coil embolization with Neuroform stent-assisted technique is a safe and effective clinical therapy. It can effectively broaden the extent of indications in treating intracranial aneurysms by using interventional technique.

Objective To evaluate the clnical value of percutaneous nephrolithotomy combined with flexible cystoscope in the treatment of complicated renal calculi.Methods Data of 53 cases of complex renal calculi treated with single channel percutaneous nephrolithotomy combined with flexible cystoscope from July 2011 to September 2013 were analyzed retrospectively.There were 31 males and 22 females.Their age ranged from 26 to 74 years with a mean age of 49 years.Thirty-two cases were located on the left side,19 cases right,2 cases bilateral,21 cases of staghorn calculi and 32 cases of multiple stones.All the stones were filled in 2 or more calyces,with 7 cases in upper ureteral stones at the same time and 2 cases in solitary kidney.The longest diameter of stones was between 2.5 cm to 4.6 cm,with an average of 3.7 cm.There were 39 cases with hydronephrosis and the separation of the collection system was 2.0-5.1 cm with an average of 3.8cm.The period which patients suffered from stones was from 1 month to 6 years.Fourteen cases underwent ESWL and 6 cases underwent open operation before percutaneous nephrolithotomy.All patients underwent single channel percutaneous nephrolithotomy under the guidance of color Doppler ultrasound,and the channel of puncture was expanded to 24 F.Results Fifty-three cases (55 sides) were performed successfully in one-stage sugery and the operation time was between 85 to 170 min,with an average of 119 min.Thestone clearance rate was 89％ (49/55) and postoperative hemoglobin decreased 3.9-9.2 g/L with an average of 6.1 g/L.The hospitalization time was 8 to 12 days with an average of 9.2 days.Two cases had hemorrhage of about 500 ml after surgery and the renal hemorrhage stopped after clamping of renal fistula without blood transfusion.Two patients suffered from fever on surgery day and 1 patient on one day after surgery,and the body temperature returned to normal level after anti-infection treatment for 2 or 3 days.No renal perforation,fluid pneumothorax or damaged surrounding organs occurred.6 patients had residual stones,among which 2 were treated by two-stage operation and 4 were treated with extracorporeal shock wave lithotripsy.Conclusion Percutaneous nephrolithotomy combined with flexible cystoscope has little trauma and high stone clearance rate in the treatment of complex renal calculi with high clinical value.

Objective To investigate the morphologic change and phosphatidylserine (PS) exposure of erythrocytes in sepsis patients.Methods 30 healthy volunteers (control group)and 30 sepsis patients were enrolled in this study and were collected venous sampling.Monitoring included Wright's staining blood smear test,erythrocyte aggregation index and the ratio of PS exposure of erythrocytes.A flow-cytometric assay based on FITC-Annexin V was used to measure the PS exposure of erythrocytes.Results The morphological changes of red blood cells included acanthocyte,lachrymiform,rouleaux,spherocyte in sepsis patients,and the peripheral blood erythrocyte aggregation and aggregation index were significantly higher than that of the healthy control group (P＜0.05).The percentage of PS exposure of erythrocytes in sepsis patients were significantly higher than that of healthy volunteers (P＜0.001).Conclusion The PS exposure of erythrocytes were significantly higher in sepsis patients,and the morphology of red blood cells is obvious abnormal.

Objective To investigate the effects of inhibitor of growth 5 (ING5) gene on the proliferation, apoptosis, migration and cell cycle of human breast cancer Bcap-37 cells.Methods The eukaryotic ING5-expressing plasmid and GFP-empty plasmid were steadily transfected in Bcap-37 cells, the expression of green fluorescent protein was measured with fluorescence microscopy, and the high expression of ING5 was measured by real time-PCR. Bcap-37-ING5 cells served as the experimental group, Bcap-37-GFP cells as the mock group and Bcap-37 as the control group. The effects of ING5 on the proliferation were detected by MTT, the cell cycle and apoptosis were detected by Flow cytometry, and the cell migration was detected by cell wound scratch assay and Transwell experiment.Results Bcap-37 cell lines steadily expressing ING5 protein with GFP-tag were acquired by stable transfection. ING5 over-expression inhibited the proliferation and led to G2 arrest of Bcap-37 cells, increased cells apoptosis and decreased the cell migration ability (P<0.05).Conclusion ING5 over-expression may have reverse effect for malignant phenotype of breast cancer cells, and may be employed to indicate the biomarker of prognosis of breast cancer patients and regarded as a target of gene therapy.
