Objective To evaluate the effect of amniotic products after transcervical resection of uterine adhesions (TCRA). Methods This study was carried out in 57 patients with intensive degree of intrauterine adhesions (IUA) who had been treated by TCRA between Jun. 2013 to Jun. 2014. These patients were devided into two groups randomly. In group amnion, 29 patients were placed amniontic scaffold balloon after TCRA;in group balloon, 28 patients were placed Foley′s balloon after TCRA. The two groups′balloons were taken out after TCRA 7 days. All patients were taken artificial cycle treatment. The uterine cavity form and the menstruation of 2 groups were observed in 3 months after TCRA. Results In group amnion, IUA score dropped from 10.1±0.5 preoperatively to 3.2±1.5 postoperative (P<0.01), in group balloon, IUA score dropped from 10.1 ± 0.5 preoperatively to 6.3 ± 2.5 postoperative (P<0.01). In group amnion, the menstrual score increased from 13.3 ± 4.4 preoperatively to 32.6 ± 5.5 postoperative (P<0.01), in group balloon, the menstrual score increased from 11.1±5.8 to 26.5±5.6 (P<0.01). The menstrual improvement of group amnion was better than that of group balloon significantly (P=0.002). In group amnion, the recurrence rate of adhesion was 21%(6/29), in group balloon, the recurrence rate of adhesion was 36%(10/28). There was no significant difference (P=0.248). The pregnancy rate of group amnion was 28%(8/29), the pregnancy rate of group balloon was 21%(6/28). The difference of pregnancy rate in two groups was not significant (P=0.760). Conclusion This small sample observation indicate that amniotic products used in the treatment of intensive IUA could improve menstrual, reduce the recurrence of adhesion, but the impovement of the pregnancy rate should be confirmed by large sample observation.

Objective To investigate the risk factors for the prognosis of radical resection in elderly patients with colorectal cancer.Methods A total of 416 patients with colorectal cancer aged over 65 years were analyzed retrospectively,who came from Peking University First Hospital and Beijing Hospital from July 2008 to July 2011.Survival analysis was conducted by Kaplan-Meier and the survival rate was compared by Log-rank method.Multivariate analysis was conducted to analyze the prognostic factors by Cox regression.Results In this group of patients,the age was(74.3 ±5.4)years,and the post operative 5-year survival rate were 84.5％,77.3％,48.2％ respectively for staging Ⅰ,Ⅱ,Ⅲ patients.Univariate analysis showed that age,ASA score,co morbidity,preoperative hypohemia,preoperative hypoalbuminemia,postoperative complications,elevated preoperative carcinoembryonic antigen (CEA),intraoperative blood loss,perioperative blood transfusion,vascular cancer embolus,nerve invasion,depth of invasion,lymph node metastasis,tumor TNM stage and adjuvant therapy were correlated with the prognosis.Multivariate analysis showed that age ≥75 years,co morbidity,postoperative complications,preoperative albumin＜30 g/ L,depth of invasion,and lymph node metastasis,tumor TNM stage and adjuvant therapy were the independent risk factors for prognosis.Conclusions The risk factors for prognosis after radical resection in elderly patients with colorectal cancer include age≥75 years,co-morbidity,postoperative complications,preoperative albumin ＜30 g/L,depth of invasion,and lymph node metastasis,tumor TNM stage and adjuvant therapy.

Objective To observe the hemodynamic effects of open-loop target controlled infusion (OLTCI) and closed-loop target controlled infusion (CLTCI) of propofol and fentanyl for general anesthesia induction. Methods Twenty-four female patients with ASA grade I-II who were performed thyroidectomy were randomly allocated into two groups: OLTCI group and CLTCI group(n=12). In OLTCI group, anesthesia induction and maintenance were performed with propofol and fentanyl at the target concentrations of 3 ?g/mL and 3 ng/mL, respectively. In CLTCI group, double CLTCI were performed. Titrations of propofol and fentanyl were guided with bispectral index (BIS) and product of systolic pressure and heart rate (HR). Initiative concentrations of this closed-loop system were 3 ?g/mL and 3 ng/mL, step-up or step-down concentrations were 0.5 ?g/mL and 0.5 ng/mL, and the highest concentrations were 6 ?g/mL and 5 ng/mL, respectively. HR, mean arterial pressure (MAP), HR variability, BIS value and the dosages of propofol and fentanyl in various time of the two groups were recorded. Results One min after intubation and simulative incision stimulation, BIS value of both groups were increased, but the BIS value in CLTCI group was less increased than OLTCI group(P

Objective:To investigate if chloride channel ClC-2 could be phosphorylated by mitogen activated protein kinase(MAPK) for further study of its regulation mechanism in proliferation and differentiation of cells.Methods:The coding sequence containing the cytosolic C-terminus of ClC-2 was amplified from pSPORT1/ClC-2 plasmid,including rabbit ClC-2 cDNA, by polymerase chain reaction(PCR),the fragment was cloned into pGEX-4T-1 plasmid for the construction of GST-tagged fusion protein expressing vector, pGEX-4T-1/ClC-2CT.After being identified by enzyme digestion and sequencing, the recombinant vector was transformed into a strain of E.coli BL21. The expression of GST-tagged fusion protein was induced with IPTG and purified with Gluthathion Sepharose 4B affinity chromatography. Then the phosphorylation of ClC-2 by MAPK was examined by using phosphorylation assays in vitro.Results:The construction of pGEX-4T-1/ClC-2CT recombinant vector was proved by enzyme digestion and sequencing. The purified fusion protein GST/ClC-2CT could be phosphorylated by MAPK, however the GST could not.Conclusion:Chloride channel ClC-2 can be phosphorylated by MAPK.

Objective To assess the efficacy and safety of ketogenic diet(KD) on refractory epilepsy in children.Methods KD treatment was designed to observe the effects for 12 weeks.Totally 22 children with 16 boys and 6 girls were enrolled in the study.The epileptic syndromes included infantile spasms(13 cases),Lennox-Gastaut syndrome(4 cases),Dravet syndrome(2 cases),and the unclassified(3 cases).The KD was prepared according to the modified Johns Hopkins regimen.Urinary ketones were measured every day to ensure that ketosis state and parents′ diaries were kept to find out when it started to work and the change of seizure frequency.Effects of KD was evaluated by Engel standard.Blood chemistry was done at baseline,4 weeks and 12 weeks to analyze the effects of KD on metabolism.Side effects were monitored and treated.Results All cases completed the KD regimen for at least 2 weeks,19 cases for at least 4 weeks,and 10 cases for at least 12 weeks.Sixteen out of 22 children experienced the seizure reduction within 3 weeks(1-15 d),especially in the first week,and seizure free appeared within 5 weeks(1-32 d) in 8 cases.Overall,the diet achieved the seizure-free in 36.4%(8/22 cases) and an over 90% of seizure frequency reduction in 22.7%(5/22 cases).The efficacy of KD seemed not correlated with the sex,age,etiopathogenisis,and syndromes and so on.Blood chemistry suggested a normal range of glucose level at 4 weeks,though higher than that at the baseline.The blood triglyceride and total cholesterol level at 12 weeks increased strikingly,even beyond the normal range compared with the baseline.The side effects mainly including transient gastrointestinal symptoms and metabolic disturbances were mostly tolerable.Conclusions KD is probably a feasible therapy on refractory epilepsy in children,with quick and high efficacy and few side effects.

Objective To compare the bone mineral density of the regions of femoral and tibial tunnels for anterior cruciate ligament(ACL)reconstruction in order to provide reference for the choice of optimal screw diameter for interference fixation.Methods Thirty healthy volunteers aged from 18 to 35 years were enrolled in our study,and the dual-energy X-ray absorptiometry(DEXA)was used to measure the bone mineral density of femoral and tibial tunnel regions of the right knee.All the right knees of the volunteers were also scanned by spiral CT and three-dimensional reconstruction technique was utilized to determine the circular sections that pass through the longitudinal axis of the femoral and tibial tunnels separately.The CT gray scale values of the Sections were measured.From August to October 2010,9 patients who had been diagnosed as ACL rupture underwent the operation of ACL reconstruction,and cylindrical cancellous bone peg was removed from the femoral and tibial tunnel respectively during the operation.Volumetric bone mineral density of the bone pegs were measured by using a standardized immersion technique according to Archimedes’ principle.Results Measured by DEXA,bone density of the femoral tunnel region arid tibial tunnel region were(1.162±0.034)g/cm2 and(0.814±0.038)g/cm2 respectively.The difference was significant between the femoral and tibial tunnel region(t=9.11,P=0.000).The CT gray scale value of the section for femoral tunnel region was(211.7±11.5)Hu,while that of the tibial tunnel region was(104.9±7.4)Hu.There was statistically significant difference between them(t=10.15,P=0.000).The volumetric bone mineral density of the bone peg from femoral tunnel and tibial tunnel were(2.80±0.88)g/cm3 and(1.88±0.59)g/cm3 respectively.The difference was statistically significant(t=4.32,P=0.002).Conclusion For ACL reconstruction,bone mineral density of femoral tunnel region is higher than that of the tibial tunnel.

Objective To explore the influence of type 2 diabetes mellitus combined with subclinical hypothyroidism on diabetic vascular complications.Methods One hundred and two patients with type 2 diabetes mellitus were selected.The serum free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),anti-thyroid peroxidase antibody (TPO-Ab),thyroglobulin antibody (TG-Ab) levels were measured by chemiluminescence method.The patients were divided into type 2 diabctes mellitus combined with subclinical hypothyroidism group (47 cases) and type 2 diabetes mellitus with normal thyroid function group (55 cases) according to the thyroid function.The glycated hemoglobin (HbA1c),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),triacylglycerol (TG),high-density lipoprotein cholesterol (HDL-C),urea nitrogen,creatinine and albumin levels were measured.The estimated glomerular filtration rate (eGFR) was calculated according to the formula of modification of diet in renal disease (MDRD).The presence of diabetic retinopathy was examined by fundus examination,and the presence of lower limb artery lesions was measured by vascular ultrasound.All indicators were compared between 2 groups.Results There were no statistical differences in age,disease course,HbA1c,body mass index (BMI),TC,TG,HDL-C,LDL-C,incidence of lower limb artery lesions and incidence of diabetic retinopathy between 2 groups (P＞ 0.05).TheeGRF in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significantly lower than that in type 2 diabetes mellitus with normal thyroid function group:(83.74 ± 21.55) ml/(min· 1.73 m2) vs.(115.02 ± 12.29) ml/(min· 1.73 m2),and there was statistical difference (t =4.274,P ＜ 0.01).The incidence of diabetic nephropathy in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significanlty higher than that in type 2 diabetes mellitus with normal thyroid function group:48.9％ (23/47) vs.23.6％(13/55),and there was statistical difference (x2 =7.103,P＜ 0.01).Logistic regression analysis showed that subclinical hypothyroidism was a risk factor for diabetic nephropathy (OR =0.524,95％ CI 0.12-0.93,P ＜ 0.05),but it was not the risk factor for diabetic retinopathy (OR =0.618,95％ CI0.19-2.16,P =0.475) and lower limb artery lesions (OR =0.485,95％ CI 0.32-2.13,P =0.689).Conclusion Subclinical hypothyroidism in patients with type 2 diabetes mellitus has no obvious effect on lower limb arterial complications and diabetic retinopathy,but may increase the risk of diabetic nephropathy.
