To explore novel coumarin derivatives with more potent anti-proliferative activity, a series of novel compounds were designed and synthesized by linking Schiff base and N, N-bis (2-chloroethyl) amine pharmacophore of nitrogen mustards to the coumarin's framework. Their structures were confirmed by 1H NMR, MS and element analysis techniques. In vitro anti-proliferative activities were evaluated against HepG2, DU145 and MCF7 cell lines by the standard MTT assay. The results showed that some of the target compounds exhibited strong anti-proliferative activities against selected tumor cells, and compounds 7c, 7f, 7g, 7h and 7q were better than or equal to the activities of positive control, they deserved further development.

The study is to explore the effect of total glucosides of paeony (TGP)on Wnt/β-catenin signal transduction pathway expression in kidney of diabetic rats, and discuss the protection of TGP in diabetic nephropathy and possible mechanism. Ninety male SD rats of 8 weeks age were randomly divided into normal control group (n = 10) and model group (n = 80). Rats of the normal control group were fed with regular diet, while rats of the model group were fed with high-fat high-sugar diet and 4 weeks later were given an intraperitoneal injection of 35 mg x kg(-1) streptozotocin (STZ). The successfully induced type 2 diabetic rat models were then randomly divided into DM group, three TGP (50, 100, 200 mg x kg(-1) x d(-1)) treatment group and tripterygium wilfordii glycosides (8 mg x kg(-1) x d(-1)) control group. Rats of DM group and each treatment group were given high-fat high-sugar diet. At week 14, the levels of blood sugar, 24 hour urine protein, serum creatinine and blood urea nitrogen were tested. The rats were then sacrificed. Renal pathological changes were examined. Renal tissue Wnt-1 and β-catenin expressions were detected by immunohistochemical assay. Wnt-1 mRNA and β-catenin mRNA expression was semi-quantified by RT-PCR. Wnt-1 protein and β-catenin protein expression was semi-quantified by Western blot. The Result show that Wnt-1 and β-catenin expression increased in kidney of high-fat high-sugar induced type 2 diabetic rats. Compared with diabetic group, the level of serum creatinine, blood urea nitrogen, 24 h urine protein, mean glomerular area and mean glomerular volume were decreased, renal histopathology were improved, expression of Wnt-1 and β-catenin mRNA and protein was reduced in TGP group. Tripterygium wilfordii glycosides had the similar effect. In conclusion, these results showed that Wnt/β-catenin abnormal activation in kidney of type 2 diabetic rats, TGP can improve kidney damage in diabetic rats and delay the development of diabetic nephropathy by inhibit the Wnt/β-catenin signaling pathway.

Objective To investigate clinical features and therapeutic protocols of vulvovaginal-gingival syndrome(VVGS). Methods Clinical data were collected from 11 female patients with VVGS and analyzed. Results Among the 11 patients, the mean and median ages at a definite diagnosis of VVGS were both 46 years, and the average disease duration was 4 years. Painful erosive erythema was found on the vaginal vestibule in 7 patients, on the gingiva in 10, as well as on the bilateral buccal mucosa in 5. Additionally, 8 and 4 patients reported dyspareunia and vaginal hemorrhage, respectively. Seven patients were treated with low-dose oral methylprednisolone combined with hydroxychloroquine or colchicine, and the other 4 were treated with oral hydroxychloroquine alone. Furthermore, all of the 11 patients applied topical tacrolimus 0.1%ointment. Finally, 8 patients were cured or markedly improved. No obvious adverse reactions were observed in any of the patients. Conclusions VVGS mostly occurs in middle-aged women, with the vaginal vestibule and gingiva as predilection sites of painful erythema and dyspareunia as common symptoms. Patients have good responses to methylprednisolone combined with hydroxychloroquine, and hydroxychloroquine alone also shows good efficacy in patients with mild VVGS. Tacrolimus 0.1%ointment can be one of drugs for topical maintenance treatment of VVGS.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia,but active cooling with whole body surface or head cooling is both complex and expensive.The clinical feasibility of passive cooling in treatment of full term infants with severe asphyxia was investigated.Methods Thirty-two severe asphyxiated term newborns treated with hypothermia were analyzed,who were randomly divided into 2 groups:passive cooling group(n =17) and active cooling group(n =15).Active cooling group adopted MTRE ALLONTM-thermo regulatory systems,passive cooling group using natural cooling method.Hypothermia treatment time was 72 hours.At the end of treatment,the clinical manifestations,biochemical parameters and clinical efficacy of infants between the 2 groups were compared.Results During treatment all infants had no cardiac arrhythmia,hypoglycemia,sustained metabolic acidosis,blood-borne infections,local cold injury or bleeding.Infants in passive cooling group had a relatively wide range of rectal temperature fluctuations[average (33.47-0.71) ℃] and infants in active cooling group had a relatively narrow range of rectal temperature fluctuations[average (33.66 ± 0.29) ℃],but there was no statistically significant difference in their mean rectal temperature(t =1.941,P =0.055).One patient died in active cooling group,but there were no significant differences in suckling age,length of hospital stay,neonatal behavioral neurological assessment score,abnormal cranial ultrasound and MRI between the survivors of the two groups(all P ＞0.05).Conclusions In NICU,environmental temperature is relatively stable,passive cooling for asphyxiated newborns appears to be feasible for maintenance of hypothermia with a lower risk of adverse reactions.

OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

Objective To analyze the prevalence and characteristics of skin diseases in elderly patients with type 2 diabetes mellitus (T2DM).Methods Clinical out patient records for both elderly and non-elderly individuals with T2DM were collected from the dermatology department of Beijing Hospital.Statistical comparisons were performed between the elderly group and the non-elderly group on the prevalence of common skin complications and disease characteristics.Analysis was performed in the elderly group to identify any association of common skin disorders with gender,age,duration of T2DM,or level of glycosylated hemoglobin (HbA1c).Results Among 679 elderly T2DM cases,pruritus was the most common complication (26.1％),followed by eczema (21.t ％) and tinea pedis/onychomycosis (18.3％).Pruritus was more prevalent in the elderly group (177 cases,26.1％) compared to the non-elderly group (34 cases,9.8％) (x2 =6.006,P＜0.01).On the other hand,tinea pedis/onychomycosis was less prevalent in the senior group (124 cases,18.3 ％) than in the non-senior group (112 cases,32.2 ％) (x2 =37.437,P＜0.01).In the senior group,pruritus was more prevalent among male patients (105 out of 358 cases,29.3％) than among female patients(72 out of 321 cases,22.4％) (x2 =4.181,P =0.041).On average,patients with eczema were older[(72.3 ± 2.2)years] and had a longer history of T2DM [(8.3 ± 0.3)years] compared with patients without eczema[age:(65.2±1.9)years,history of T2DM:(5.2±0.1)years] (t=1.250,P=0.023 for age;t=1.680,P=0.033 for disease duration).Patients with tinea pedis/onychomycosis had higher HbA1c levels (6.7 ± 0.4) ％ than patients without tinea pedis/onychomycosis (6.1 ± 0.3) ％ (t =0.790,P＜0.01).Conclusions Pruritus is the most common skin complication in elderly patients with type 2 diabetes and is more common in elderly patients and male patients.Risk factors for developing eczema in elderly patients with type 2 diabetes may include older age and long disease duration.High levels of glycosylated hemoglobin in elderly patients with type 2 diabetes indicates increased risk for foot fungi infections.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.
