SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

Objective To explore the clinical efficacy and safety of transcatheter absolute ethanol injection treatment on varicose veins of lower extremity.Methods twenty-there patients with 25 varicose veins of lower extremity were treated by puncture of great saphenous vein above 1—2 cm of complicated inner ankle,perforating catheter to the point below the 3—4 cm of the conjunction of great saphenous vein and Femoral vein and pressing the conjunction of these two veins.Under the monitor of DSA,inject the absolute ethenal slowly while retrieve the catheter little by little(one limb with varicose veins injected total volume 15—20 ml),in the mean time,using contrast agent to monitor the level of embolism until the formation of total embolism in the all great saphenous veins.Results All the cases were retrospectively followed up with CDFI examination after 3—12 months of the surgery,No blood flow were seen in the 25 embolismic great saphenous vein.Clinical symptom were alleviated obviously after 2—3 weeks of treatment;varicose veins were collapse after 3 to 7 days.Two eases of leg ulceration were healed after 4 to 6 weeks of operation.20 limbs were found mild swelling in the 2 day after the surgery.However,all the cases were disappeared after 1 to 2 weeks;4 treated limbs developed delayed paresthesia in the 3 day after the surgery,and recovered totally in the 2 weeks.No complications of deep vein thrombosis,lung thrombosis etc al,were found after operation.Conclusions Using transcatheter injection of absolute ethanol to treat varicose veins of lower extremity has the advantage of less invasion,more safety and low appearance of complications.The short term efficacy is solid while the long term effect needs further evaluation.

Pololike kinase 1(Plk1)contain an Nterminal Ser/Thr kinase catalytic domain and a Cterminal region that contains two poloboxes.As a key regulator of multiple steps during cell cycle across eukaryotic species,many proteins interact with Plk1.Plk1 is highly expressed in malignant cells and serves as a negative prognostic marker in specific human cancer types.Plk1 is a potential target for cancer therapy.Some novel smallmolecule inhibitors of pololike kinase 1 provide novel opportunities for cancerdrug discovery,such as BI 2536,ON01910.

Objective To assess the effects of gonadotropin-releasing hormone analog on glucose and lipid metabolism in girls with idiopathic central precocious puberty(ICPP).Methods A total of 26 girls (aged 6-8 years,breast stage B2) with ICPP were followed up in Department of Endocrinology,Shenzhen Children's Hospital from Jan.2008 to Jun.2011.Those girls received triptorelin therapy for 12 months.Before and the end of the 6th month,the 12th month of the treatment,body mass index(BMI) was calculated,fasting plasma glucose(FPG),fasting plasma insulin(FPI),total cholesterol,triacylglycerols,high density lipoprotein cholesterol,low density lipoprotein cholesterol,apolipoprotein A,apolipoprotein B and estradiol(E2) were measured.Insulin sensitivity was estimated by homeostasis model assessment of insulin resistance(HOMA-IR).Twenty age-matched prepuberty girls were set as controls.Results 1.Before treatment,BMI,FPG,FPI and HOMA-IR in ICPP girls had no significant difference compared with the controls.2.After 6 months treatment of triptrolin,serum E2 concentration in ICPP girls declined from(30.5 ± 9.8) ng/L at the beginning of treatment to (11.2 ± 4.6) ng/L at the end of 6th month (P ＜ 0.01) ; The end of 12 th month of the treatment,FPG and FPI had no significant difference compared with that before of the treatment,but BMI increased from(16.46 ± 1.10) kg/m2 to(18.35 ± 1.30) kg/m2,the difference was significant(P ＜0.05),HOMA-IR increased from 1.24 ±0.30 to 2.08 ±0.40,the difference was significant(P ＜0.05).3.Lipid metabolism parameters remained unchangeable after 12 months of triptrolin treatment.Conclusion Triptorelin may lead to raise of BMI and HOMA-IR in girls with ICPP at 12 months after treatment.

Objective To examine the possibility that a candidate causal species of the skin and lung tumor promotion induced by exposure to dimethylarsinic acid(DMAv)and dimethylarsinous acid(DMAⅢ),caused by the induction of oxidative stress in mice.Methods Two stages lung tumotigensis animal model induced by lung tumor initiator(4-nitroquinoline 1-oxide,4NQO)and promoter(DMAv)in ddY mice,was used to examine the effect of(-)epigallocatechin gallate(EGCG)on DMAv promoting lung tumorigenesis.Two stages skin tumorigenesis animal model induced by skin tumor initiator[dimethylbenz(α)anthracene,DMBA]and promoter(DMAⅢ)in hairless mice.was used to examine the effects of DMAⅢ in skin tumorigenesis and histopathology.The goxo-2'-deoxyguanosine (8-oxodG)in lung and epidermis were analyzed by HPLC.Results The incidence of lung tumors and 8-oxodG level of lung tissue decreased significantly in 4NQO+DMAv+EGCG group.compared with 4NQO+DMAv group (0.89±0.30 vs 4.00±0.82,1.21±0.09 vs 1.53±0.32,P＜0.01).The incidence of severe keratosis in DMBA+ DMIⅢ group was more than that in DMBA group(25 vs 10,P＜0.05).An significant elevation of 8-oxodG in epidermis was observed in 0.5 h[(1.67±0.17)/105 dG],1.0 h[(1.62±012)/105 dG],2.0 h[(1.66±023)/105dG], 3.0 h[(1.60±0.15)/105 dG],compared with 0 h[(1.25±0.11)/105 dG],being significant(P＜0.05).Conclusion tumor promotion due to DMAv administration is mediated by DMAⅢ through the induction of oxidative stress.

OBJECTIVE: To evaluate the long-term efficacy and safety of ultrasound-guided percutaneous nephrolithotomy (PCNL) in the treatment of patients with solitary kidney stones. METHODS: The clinical data of 22 patients with solitary kidney stones treated with PCNL in Peking University People's Hospital from September 2008 to June 2014, with the follow-up data of more than 5 years were analyzed retrospectively. Perioperative indicators, postoperative stone free rate (SFR) and incidence of complications were recorded. Ultrasonography was used to evaluate the long-term stones recurrence rate. Serum creatinine and estimated glomerular filtration rate (eGFR) were used to assess the long-term renal function. RESULTS: In this group of 22 patients, the average age was (50.3±11.8) years, with 10 cases of anatomic solitary kidneys, 12 functional solitary kidneys, and the median stone diameter was 1.65 (1.1-3.9) cm. All the patients had multiple stones, including 7 cases of staghorn stones. The median pre-operative serum creatinine was 104.5 (60.0-460.0) μmol/L, and the mean eGFR was (60.3±29.4) mL/min, showing no statistically significant difference compared with that before surgery. The mean operative time was (88.2±42.0) min, and there were 11 cases of single-channel and double-channel PCNL. The median serum creatinine on the first day after surgery was 102.0 (63.0-364.0) μmol/L, and the mean eGFR was (58.0±25.1) mL/min. The mean postoperative hospital stay was (8.7±5.2) days. In this group, 5 patients (22.7%) presented short-term complications, among which 4 patients presented postoperative infection and massive hemorrhage at the same time, which improved after conservative treatment, and 1 patient presented pleural injury and improved after closed thoracic drainage. Two patients (9.1%) developed long-term complications, and ureteral stricture occurred 3 months after operation, which improved after balloon dilatation. The median follow-up time was 6.2 (4.7-11.1) years. The median serum creatinine at the last follow-up was 104.0 (72.4-377.0) μmol/L, and the mean eGFR was (60.1±23.7) mL/min, showing no statistically significant difference compared with that before surgery. Renal function decreased in 6 patients (27.3%). Initial and final SFR were 72.7% and 100%, respectively. During the 6.2-year follow-up, 9 patients (40.9%) experienced recurrence of kidney stone. After stone recurrence, 13 lithotomy surgeries were performed, and the SFR by the latest follow-up was 63.6%. CONCLUSION This study had the longest follow-up time for patients with solitary kidney stones after PCNL reported at home and abroad. Ultrasound-guided standard PCNL was safe and effective in the treatment of solitary kidney stones. Long-term follow-up results showed that the recurrence rate of kidney stones was still high, but the long-term renal function was stable after operation, and some patients showed mild renal function decline.

OBJECTIVETo study the thymidine phosphorylase (TP) expression in different types of cancer and its correlation with tumor microvessel density (MVD).

METHODSThe expression of TP and MVD was detected by immunohistochemistry method. In a series of 251 cancer patients there were 48 patients with gastric cancer, 53 with colorectal cancer, 47 with breast cancer, 56 with cervical cancer, 47 with lung cancer. Normal gastric (n = 25), colorectal (n = 25), cervical (n = 17) and lung (n = 25) tissues around the cancer were also examined.

RESULTSThe TP expression rate was 64.6% in gastric cancer, 67.9% in colorectal cancer, 80.9% in breast cancer, 82.1% in cervical cancer, and 63.8% in lung cancer, which was significantly higher than that in normal tissues (P = 0.0000). TP expression was positively correlated with MVD in gastric, colorectal, breast, and cervical cancers. The correlation was not statistically significant in lung cancer.

CONCLUSIONThis study indicates that TP overexpression in cancer may be associated with tumor angiogenesis.

Objective To observe the injury of high intensity focused ultrasound combined with radiotherapy (RT) to the pancreas,the unintended abdominal tissues and organs of swine in vivo.MethodsAccording to the criterion to grade the gross and histological injury of the pancreas and the unintended tissue,the scores of injury between the groups to get the data of safety and feasibility of high intensity focused ultrasound(HIFU)combined with RT were compared.Results There was a better tolerance in each group and no fatal complication was observed.For the pancreas there was significant difference for the combined group compared with the other groups.For the unintended target tissue there was no significance difference except the control group with the other groups.Conclusion HIFU combined with RT can increase the injury to the pancreas of the swine compared with HIFU alone; while there was no increase for the injury to the unintended target tissue.The main toxicity of combination treatment is the toxicity of RT and can be tolerated by the animals.If the HIFU treatment is strictly controlled,the combination of HIFU and RT is safe and feasible.

OBJECTIVESevere myoclonic epilepsy of infancy (SMEI), or Dravet syndrome, is a severe epileptic encephalopathy. This study aimed to investigate the clinical features and genetic diagnosis of SMEI.

METHODSThe electroclinical data and the mutation of SCN1A gene in 13 children with SMEI were analyzed.

RESULTSOf the 13 children, 10 were males and 3 were females. Eight of them had family history of febrile seizures. The average age of seizure onset was 5.6 months, with a range of 2 to 9 months. The initial seizure was a febrile seizure in 9 patients (69%). Generalized or hemiclonic seizures were often triggered by fever. Eight patients had a history of febrile status. Afebrile seizures occurred from 2 months to 21 months of age. All patients went on to develop multiple seizure types. Generalized tonic clonus seizures (GTCS) were found in 11, partial seizures in 12, atypical absence in 10. Myoclonic seizures were presented in all patients. Twelve patients had 3 or more seizure types. Seizures of all patients had a characteristic of temperature sensitivity. The precipitating factors included fever, hot bath and vaccination. Nine patients (69%) had a history of status epilepticus. Delay in mental development was present in 11 cases, ataxia in 5 and pyramidal sign in 2. EEG was normal in most patients in the first year of life, followed by generalized, focal and multifocal discharges. Brain MRI was abnormal in 2 cases. Seizures were not completely controlled in all patients. Carbamazepine and lamotrigine aggravated seizures in some patients. SCN1A gene mutation was found in 10 cases, including seven missense mutations, two nonsense mutations and one frame shift mutation.

CONCLUSIONThe clinical features of SMEI were seizure onset within one year of age, first event is often a febrile seizure; multiple seizure types and mental delay occurred after the second year of life; seizures have a characteristic of temperature sensitivity; EEG was normal in the first year of life, followed by generalized, focal or multifocal discharges; early diagnosis by testing SCN1A mutation guides selection of antiepileptic drugs.

BACKGROUNDA few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection (AD). There is, however, no systemic investigation regarding the role of plasma C-reactive protein (CRP) and white blood cell (WBC) levels in predicting in-hospital clinical events of acute type A AD.

METHODSThe levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD. The variations of plasma CRP and WBC levels in different time windows (admission, 1, 2, 3, 4, 6, 8 days) in patients with acute type A AD were analyzed between patients with events and without events.

RESULTSDuring hospitalization, five patients died, and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived (P < 0.01, respectively). Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD. Additionally, patients with complication of pleural effusion showed higher CRP and WBC levels (P = 0.046, P = 0.018, respectively). Lower WBC levels were found in survived patients treated medically (P = 0.001). Moreover, mean CRP and WBC levels had positive correlations with aortic diameter (r = 0.364, P = 0.000; r = 0.333, P = 0.000, respectively) and age (r = 0.270, P = 0.000, respectively), while negative correlations with the time from onset of symptoms to hospital admission (r = -0.229, P = 0.000, r = -0.200, P = 0.002, respectively). Univariate analysis showed that age ≥ 65 years, CRP ≥ 12.05 mg/L, WBC ≥ 12.16 × 10(9)/L, aortic diameter ≥ 48 mm, pleural effusion and diastolic blood pressure ≥ 105 mmHg were associated with hospital mortality. While CRP ≥ 12.05 mg/L, WBC ≥ 12.16 × 10(9)/L, aortic diameter ≥ 48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis.

CONCLUSIONSThe results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD, especially death during hospitalization. Therefore, further study enrolling larger cohort, prospective study would be warranted.
