Objective To investigate the effects of hedysarum polybotys saccharide (HPS) on lipid metabolism and the expression of stearoyl-CoA desaturase-1(SCD-1) gene in rats with non-alcoholic fatty liver disease (NAFLD). To discuss the interfering effects of HPS on NAFLD. Methods The SD rats were randomly divided into the blank control group and the experiment group. Rats in the experiment group were fed with lipid rich food for 8 weeks to establish model and were randomly divided into model group, drug positive group and HPS group. After 8 weeks of drug intervention, the level of ALT, AST, TC, TG, HDL-c and LDL-c were measured with automatic chemistry analyzer, and expression of SCD-1 gene was measured by semi-quantitative polymerase chain reaction.Results Compared with blank control group, serum ALT, AST and TC, TG, LDL-c of model group were higher (P<0.05,P<0.01), the level of HDL-c of model group and the expression of SCD-1 gene were lower (P<0.01). Compared with model group, HPS was useful to decrease serum ALT, AST, LDL-c, TC and TG (P<0.05,P<0.01), and increase the level of HDL-c (P<0.01) and the expression of SCD-1 gene (P<0.01).ConclusionHPS had a positive effect on regulating lipid metabolic disturbance of NAFLD rats and promoting the expression of regulatory gene SCD-1.

Objective: To study the contents and constituents of LSPC (procyanidins from Lotus Seedpod) and its chemoprophylactic effects on 9,10-dimethyl-1,2-benzanthracene (DMBA)-induced golden hamsters buccal-pouch carcinomas. Methods: ESI-MS was used to analyze LSPC, and the change of body weight, mortality during test, and the value of serum MDA, GSH-Px, T-SOD,the gross and pathological change of buccal-pouch mucosa were investigated when golden hamsters were via gastric intubation or the buccal pouch mucosa was smeared with 100mg/(kg bw?d)LSPC. Results and conclusion: The contents of LSPC exceeded 98% and mono-, di-, tri-, tetrameric procyanidins as well as di-, trimeric galic ester were constituted of LSPC with molecular weight ranging from 290-1154. LSPC had chemoprophylactic effects on DMBA-induced golden hamsters buccal-pouch carcinomas, and the effect was superior through smearing LSPC rather then via gastric intubation .

The inverse cancer comorbidity in schizophrenia patients may be related to the genetic factors ,involving the regu‐lation of apoptosis .The tumour suppressor gene TP53 ,involved in neural apoptosis ,is one of the potential candidate genes associat‐ed with schizophrenia which might reduce colorectal cancer risk .We recruited 270 schizophrenia patients and 312 colorectal cancer patients without schizophrenia .To examine the genetic association between schizophrenia and colorectal cancer ,we analysed eight SNPs (rs12951053 ,rs1625895 ,rs2909430 ,rs9895829 ,rs1042522 ,rs8079544 ,rs8064946 ,rs17806770) covering 14 .35 kb in the re‐gion of TP53 .We observed that one of the eight genetic polymorphisms showed statistically significant differences between the colo‐rectal cancer subjects and the schizophrenia subjects (rs12951053 ,P=0 .000 1 ,OR 1 .70 ,95% CI 1 .30-2 .23) .In addition ,the hap‐lotype of A‐G (rs12951053‐rs8064946) ,giving a global P=0 .001 8 ,was the most significant .Our data indicate that the polymor‐phisms of rs12951053 in TP53 confer reduced susceptibility to colorectal cancer and suggest a potential protective mechanism a‐gainst colorectal cancer in the schizophrenia patients of Han Chinese origin .

ObjectiveTo investigate the etiology and prognosis of asymptomatic hematuria in children.MethodsThe etiological factors, clinical features and prognosis of asymptomatic hematuria were analyzed retrospectively in 431 children from Jan. 2001 to Dec . 2014. ResultsIn 431 children (197 males and 234 females) with asymptomatic hematuria, the mean age of ifrst visit was 5.52±2.77 years (8 months-17 years). Four hundred and twenty-ifve cases had persistent microscopic hematuria and 6 cases had gross hematuria. Three hundred and iffteen cases (73.1%) were glomerular hematuria, among which 286 cases were isolated hematuria, 5 cases were acute glomerulonephritis, 13 cases were minimal change glomerulopathy, 4 cases were IgA nephropathy, 4 cases were mesangial proliferation glomerulonephritis and 3 cases were thin basement membrane nephropathy. One hundred and thirty-six cases (31.5%) were non-glomerular hematuria, among whom 113 cases were left renal vein entrap-ment syndrome, 17 cases were idiopathic hypercalciuria, 4 cases were kidney stone, 1 case was urinary tract infection and 1 case was left kidney absence. The mean follow-up period was 3.05±2.69 years (0.5-13.5 years). One hundred and forty-ifve patients showed the resolution of microscopic hematuria, among whom 110 cases (75.8%) had the resolution in 3 years after the ifrst visit. In 24 cases with family history of hematuria, only 6 cases showed the resolution. At the end of the follow-up, renal function remained stable in all children.ConclusionsThe onset age of asymptomatic hematuria in children varies widely, and most of them are glomerular hematuria. Most children with isolated hematuria show resolution within three years after the ifrst visit. The children with familial hematuria may last longer. The isolated hematuria has good prognosis but needs to be followed up.

Objective To investigate the effects of phosphocreatine postconditioning on cerebral ischemia-reperfusion(IR)injury in rats.Methods Thirty-six SD rats were randomly divided into three groups:groups Sham,IR (treated with normal saline)and PCr.IR was induced by intraluminal middle cerebral artery occlusion (MCAO).All treatments were given intravenously at the begining of reperfusion.Twenty-four hours after the reperfusion, neurological deficit score and magnetic resonance scan were performed.serum concentrations of malonaldehyde and 4-hydroxynonenal,cere-bral infarct volume and destruction of cerebral cortex were estimated.Neuronal apoptosis was further assessed by immunohistochemistry and immunofluorescent staining of caspase-3 and NeuN. Results Compared with group IR,phosphocreatine significantly decreased neurological deficit score, infarct volume,malonaldehyde and 4-hydroxynonenal levels(P < 0.05 ).Cortex structure was more complete,as well as neuronal apoptotic index was smaller in group PCr (P <0.05).Conclusion PCr can reduce cerebral infarct volume,thereby promote neurofunctional recovery.The mechanism of Pcr is related to reduced oxidative stress and inhibitted apopotosis during IR.

Objective To improve the recognition of nail-patella syndrome(NPS). Methods The pathological,clinical and x-ray features of NPS in 6 cases were analysed with literature reviewed. Results The main diagnostic features of NPS included:(1)There were nail dysplasia and family history;(2) The pathological changes were bilateral,multiple bone and multiple systems involved;(3) Patients had a characteristic tetrad involving the nails,knees,elbows and the presence of iliac horns. Conclusion Based on the typical x-ray findings combined with clinical characteristics,nail-patella syndrome can be suggested.Radiography is one of the best methods for the diagnosis of this disease.

Objective To evaluate the effect of sodium potassium magnesium calcium and glucose (SPMCG) injection on the internal environment and metabolism of glucose,fat and protein in the patients undergoing craniotomy.Methods Forty-four patients of both sexes,aged 18-64 yr,of American Society of Anesthesiology Anesthesiologists physical status Ⅰ-Ⅲ,with body mass index of 18-30 kg/m2,were divided into either lactated Ringer's solution group (group R) or SPMCG injection group (group S) using a random number table.Before anesthesia induction,6％ hydroxyethyl starch 130/0.4 was infused intravenously at 15 ml · kg-1 · h-1 for 30 min,followed by iv infusion of 6％ hydroxyethyl starch 130/0.4 and corresponding volume of crystalloid solution in a ratio of 1 ∶ 2 at a rate of 5-10 ml · kg-1 · h-1 until the end of surgery.Before fluid infusion (baseline),immediately after the beginning of surgery,at 2 and 4 h after the beginning of surgery,at the end of surgery and at 1 h after surgery,arterial blood samples were collected for blood gas analysis,the pH value and concentrations of base excess,Na +,K+,Ca2+,Mg 2+and lactic acid were recorded,and the blood glucose concentration was determined.Before fluid infusion (baseline) and at the end of surgery,venous blood samples were taken for determination of the concentrations of plasma insulin,β-hydroxybutyric acid and 3-methylhistidine (3-MH).Results No hyperglycemia was found in the two groups.Compared with group R,the Mg2+ concentration was significantly increased,the concentrations of lactic acid and plasma β-hydroxybutyric acid and 3-MH were decreased (P＜0.05),and no significant change was found in the other parameters in group S (P＞0.05).Compared with the baseline,the blood glucose concentration was significantly increased after fluid infusion in the two groups,the Mg2+concentration was significantly decreased,and the concentrations of lactic acid and plasma insulin,β-hydroxybutyric acid and 3-MH were increased after fluid infusion in group R (P＜0.05),and no significant change was found in the parameters mentioned above in group S (P＞0.05).Conclusion For the patients undergoing craniotomy,SPMCG injection can maintain homeostasis,and the component 1％ glucose can inhibit the decomposition of fat and protein without inducing hyperglycemia and glucose metabolic disorders.

Objective To explore the therapeutic effect and the efficacy of external carotid artery catheterization and drug infusion therapy for severe infant hemangiomas in oral and maxillofacial regions.Methods The clinical and follow-up data of 126 cases with severe infant oral and maxillofacial hemangiomas were retrospectively analyzed in Henan Provincial People's Hospital between June 2004 and December 2009.The patients included 45 male and 81 female cases,and the average visiting age of the patients was 3.9 months (ranged 10 days to 1 year and 4 months).Among 126 patients,24 cases occurred with Kasabach-Merritte syndrome (KMS).The patients were treated with ligation of external carotid artery,insertion of a tube inside the lesion and injection of 400 g/L Carbonyldiamide after operation.Methylprednisolone was added in infusion if the patients were combined with KMS.Results The mean follow-up period was 6.1 years (ranged 4.3 to 10.2 years).All of 126 cases were cured through the management including external carotid artery catheterization and drug infusion therapy in 94 cases,and the combination treatment of the infusion and local Carbonyldiamide injection in 32 cases.The size of hemangiomas gradually shrank and disappeared after the therapy.The hemangiomas in 105 cases disappeared completely in 6-12 months,and 21 cases disappeared in 1-2 years.Twenty-four patients were complicated with KMS.The thrombocyte count and blood coagulation function also returned to normal after the therapy.Among the 24 cases,the thrombocyte count in 13 cases was back to normal within 3-7 days,and 7 cases within 8-14 days.In the remaining 4 cases,it normalized within 15-30 days.The weight,height,immunity of the patients were in keeping with the healthy counterparts after long term follow-up.And no serious adverse effect was observed.Conclusions For severe infant hemangiomas in oral and maxillofacial regions,the external carotid artery catheterization and drug infusion therapy can obviously shorten the treatment time,and reduce the drug side effects.It is a better and more reliable treatment method.

Objective To observe the bone density, serum osteoprotegerin (OPG) level,relevant parameters of bone metabolism and sex hormones in elderly men with osteoporosis before and after treatment with oral Fosamax for 3 years. Methods The serum OPG level was compared between 72 randomly selected elderly male patients with osteoporosis and age-matched healthy controls. The bone density, serum OPG level, sex hormones, serum calcium and phosphorus,parathyroid hormone (PTH), osteoealein and urine type Ⅰ collegen crosslinked N-telopeptides (NTX),urine calcium and cretinine were tested in all elderly male patients with osteoporosis before and after 3 years of oral Fosamax treatment. The role of OPG in anti-osteoporotic therapy was studied by comparison of the parameters tested during the course of treatment. Results The serum levels of OPG osteoealcin, PTH and urine NTX were obviously higher in elderly men with osteoporosis than in healthy controls [(10.56±2.56) pmol/L vs. (8.91±2.20) pmol/L, (9.544±4.40) g/L vs. (6.774±2.87)rig/L, (70.39±35.58) ng/L vs. (47.11±21.80) ng/L, (72.06±9.78) nmol/L vs. (63.36±14.61)nmol/L, all P<0.05]. After treatment with oral Fosamax , the bone density was significantly increased. However, serum levels of OPG[(8.23±2.96)pmol/L], osteocalcinE(6.18±2.27)μg/L],PTH[(40.46±14.43) ng/L] and urine NTX[(64.83±11.40) nmol/L] were significantly decreased after treatment (all P<0.05). Spearman analysis showed that the improvement of bone density after treatment was closely associated with serum OPG level. Conclusions Serum OPG level in elderly patients with osteoporosis is much higher than that in control group. The improvement in bone density after treatment is associated with the decrease in OPG level. Bone density and relevant parameters of bone metabolism can be improved in elderly male patients with osteoporosis by using oral Fosamax.

BACKGROUND:Shengjiyuhong ointment has been reported to inhibit hypertrophic scarring. OBJECTIVE:To verify the effects of Shengjiyuhong ointment on hypertrophic scarring of in a rabbit ear model. METHODS:Each ear of thirty-six Japanese rabbits was used to make four 1-cm-diameter circular ful-thickness skin wounds with the entire perichondrium removed. Final y, 288 wounds were made and randomly divided into 6 groups:model, negative control (no drugs were administered), low-, moderate-, high-crude herbal dose drugs (Shengjiyuhong ointment was administered topical y at concentrations of 8.39%, 25.18%, and 75.54%), and positive control (recombinant bovine basic fibroblast growth factor was administered topical y). Shengjiyuhong ointment was administered twice daily til wound healing. The wounds were evaluated by the Vancouver scar scale (VSS). Scar elevation index (SEI) of scar specimens was calculated under a microscope at 40× magnification. mRNA expression levels of type I and III col agen, connective tissue growth factor, fibronectin, andα-smooth muscle actin (α-SMA) were determined by fluorescent quantitative PCR. Protein expression levels of type I and III col agen andα-SMA were detected by western blot assay.α-SMA immunoreactivity was determined by immunofluorescent staining. RESULTS AND CONCLUSION:VSS scores and SEI were significantly increased in each group at 30 days (P<0.05). VSS scores and SEI were significantly decreased in the moderate-and high-crude herbal dose drug groups and positive control groups compared with the model, negative control, and low-crude herbal dose drug groups (P<0.05 or P<0.01). mRNA expression levels of type I and III col agen, connective tissue growth factor and fibronectin, and protein expression levels of type I and III col agen andα-SMA were significantly inhibited after moderate-crude herbal dose Shengjiyuhong ointment and positive drug treatment (P<0.01). These findings suggest that Shengjiyuhong ointment can reduce hypertrophic scars by inhibiting fibroblast proliferation and col agen deposition.
