For treatment of pediatric inguinal hernia, we fabricated a device, i.e. so called "filling type pediatric hernia sac", which treats the problem from the abdominal cavity, through the abdominal and is a self-adaptive closer, using synthetic material. The device includes filling rack, self-adaptive umbrella support bar, bottom piece, outside pulling line and device fixing lines. The filling rack is composed of 2 concentric circles of 3.0 cm diameter with peripherally fixed together and can be pulled into the shapes of a ball or an olive. The supporting bar is structured of 3 pieces with 0.5 cm wide, 4.0 cm long, cross-fixed on top of the filling rack. The bottom piece is in a circular structure with a diameter of 3.0 cm, and it is connected to the filling rack bottom. Adjust positioning stay outside the fixed on the top of the device are connected at one end, and the other end free through filling the top frame connected with the bottom slice of central fixation. By using this device, we treated 37 pediatric inguinal hernia cases with 38 side-inguinal hernia successfully. The mean duration of post-operation follow-ups was 14.6 ± 5.89 months, without hernia recurrence, obvious scar and hard sections of inguinal region. This device could provide a convenient, safe and effective plugging technology for children's pediatric hernia.

Objective To investigate the skin basic conditions of normal female consumers for cosmetics who use a cream of lower than RMB 25 yuan in markets in Chengdu area.Methods Female subjects aged 25 to 45 years were recruited in Chengdu and divided into four age groups.Parameters were noninvasively tested to investigate skin baseline conditions of the two groups,including skin moisturization,trans-epidermal water loss (TEWL),color,texture and pH etc.Meanwhile,subjective scores were acquired by experienced dermatologists and self-questionnaires were collected to investigate subjects' concerns.Results Skin texture,softness,and skin color were found significantly different between age groups.The top 3 skin problems were dryness,skin color and wrinkles; the top 3 ideal skin were moisture,shining and fairness.Conclusions With similar environment and skin care habits,35-year-old is a turning point for females of decreased metabolism in the skin,as seen from skin color,elasticity,and roughness.

Objective To observe the effects of ginkgolide B (GB) on mRNA expression of foxgl and proliferation of cells in brain tissue of newborn rats with hypoxic-ischemic brain damage (HIBD).Methods A total of 128 clean 7-day-old healthy SD rats were randomly divided into sham operation group,the model group,the low-GB dose and the high-GB dose treatment groups.Classic Rice method were used to establish HIBD models in the latter 3 groups.Four hours after operation,and GB in dose of 5 mg/kg and 10 mg/kg was given to rats in the low and the high dose treatment groups by intraperitoneal injection postoperatively,once a day for 5 days,while sham operation and model groups were treated with equal physiological saline.All groups were respectively sacrificed on 3 d,7 d,14 d,28 d respectively.Quantitative real-time fluorescent polymerase chain reaction was employed to detect expression of Foxg1 gene.Then the number of 5-bromodeoxyuridine positive cell in subgranular zone was investigated by immunolluorescent stairning.Results The Foxg1 mRNA expression was observed 3 days after HIBD,peaked on 7th day,and then declined gradually; the levels of Foxg1 mRNA in the 2 treatment groups were higher than that of the HIBD group (all P ＜ 0.01) ; The expression of Foxgl at 7 d,14 d,28 d,in high-dose group were higher than those in the low-dose group (all P ＜ 0.01).The number of 5-bromodeoxyuridine positive cell was increased after HIBD,and the levels in the low-and the high-dose treatment groups were all higher than that of the model group (all P ＜ 0.05) ; the number of positive cell in high-dose treatment groups were higher than that in the low-dose treatment groups (P ＜ 0.05).Conclusions GB can promote the expression of Foxg1 gene and improve the proliferation of cells in Brain tissue after HIBD,which shows more significant efficacy in high-dose group than in low-dose group.

Post-translational modification by ubiquitin and ubiquitin-like modifiers(Ubls) is one of the most important mechanisms regulating a wide range of cellular processes in eukaryotes.Previous research showed that,through covalently modification by ubiquitin or ubls,the substrate proteins can be regulated in many different ways like stability,subcellular localization,enzymatic activity,protein-protein interaction and so on.Therefore,we believe,that ubiquitin and ubls play very important roles in cellular and biological processes by modifying plenty of proteins.To better understand the ubiquitin and ubls system,proteomic approaches have been developed to purify and identify more protein substrates.Large-scale idendification of ubiquitin/ubls-modification sites by mass spectrometry is particularly important for understanding the molecular mechanism and function of ubiquitin/ubls modification.Upto the present,more and more scientists are getting interested and participating in proteomics research of ubiquitin/Ubl modifications.This review summarizes the rencent results in this field.

Objective To evaluate the efficacy of siege scheme of TCM for acute cerebral infarction bowel and visceral strike (block pattern). Methods Totally 110 patients were randomly divided into TCM siege scheme group (55 cases) and control group (55 cases) by randomized parallel controlled study with foresight and multicenter. The control group was treated with the standardized treatment, and TCM siege scheme group was treated with TCM siege scheme, including mild hypothermia TCM pillow therapy, TCM rectal enema, and other multiple treatments based on the standardized treatment. The Glasgow Coma Scale (GCS), the time of pulling out urine tube and nasal feeding tube, and the number of tracheotomy caused by illness changes of the two groups were compared. Results The baseline data of two groups have good comparability (P>0.05). On 10, 15 d of treatment, the number of lucid people in the TCM siege scheme group was significantly more than that in the control group (P<0.05). Compared with the control group, treatment group had less number of tracheotomy, and shorter time of success pulling out urine tube and nasogastric feeding tube (P<0.05). Conclusion TCM siege scheme can improve the consciousness of ischemic stroke in patients with acute cerebral infarction bowel and visceral strike, reduce complications, shows shorter successful pull urine tube and nasogastric feeding, and provides guarantee conditions for further rehabilitation treatment.

Objective To observe the effect on Foxg1 gene expression in the subgranular zone (SGZ) of cerebral tissue from neonatal rats with hypoxic-ischemic brain damage (HIBD) after transplantation of neural stem cells (NSCs) derived from umbilical cord blood.Methods Mononuclear cells separated from umbilical cord blood by density gradient centrifugation were cultured with orientated induction to differentiate the NSCs.The neuronal phenotype was identified using immunocytochemical methods.A total of 150 Sprague-Dawley rats were randomly divided into a sham-operation group,an HIBD group and an HIBD-NSCs group.Rats in the HIBD group and the HIBD-NSCs group were subject to ligation of the left carotid artery and then kept in a box under 8％ oxygen and 92％ nitrogen for 2.5 hours to establish the HIBD animal model.The artery was separated but not ligated in the sham operation group,which was not subjected to hypoxia.Twenty-four hours after the operation,the cultivated NSCs were transplanted by caudal vein injection into the rats in the HIBD-NSCs group.Rats were then sacrificed on the 3rd,7th,14th,21st and 28th days after the operation.Foxg1 gene expression in the SGZ was examined using in-situ hybridization methods.Results The number of Nestin-positive cells peaked on the 6th day of cultivation and then decreased by the 9th day.The Foxg1 gene was expressed in the SGZs of each group.The expression increased by the 3rd day after surgery in the HIBD and HIBD-NSCs groups,and peaked on 7th day after the operation,then declined gradually.The average expression level of Foxg1 in the HIBD group was significantly lower than that in the HIBD-NSCs group on the 7th day and thereafter.Conclusions Human umbilical cord blood mesenchymal stem cells can be induced and differentiated into neural stem cells.Foxg1 genes can still be present in the SGZ after birth.HIBD can induce the expression of Foxg1 genes.Transplanting NSCs can promote the expression of Foxg1 genes and improve morphological and functional recovery after HIBD,at least in neonatal rats.
