Objective To seek for the differentially-expressed proteins in patients with kidney-yin deficiency syndrome and to screen out the specific proteins,so as to provide evidence for the establishment of objective standard of kidney deficiency syndrome of traditional Chinese medicine (TCM).Methods Five patients with typical kidney-yin deficiency syndrome and 6 normal healthy volunteers were enrolled into the study.Plasma proteins in both groups were detected by antibody chip,and then the plasma proteins profile was compared and analyzed.Results A total of 25 differentially-expressed proteins between kidney-yin deficiency group and normal control group were found,of which 2 were up-regulated and 23 were down-regulated.Conclusion The differentially-expressed proteins in patients with kidney-yin deficiency syndrome are mainly related to immune disorder,protein biosynthesis,metabolism,oxidative stress,cell apoptosis,signal transduction,and so on.

To establish a fetal biparietal diameter (BPD)-gestational age formula based on the data of pregnant women from Xiaoshan District of Hangzhou, and to evaluate its application in prenatal screening.Data of 3500 pregnant women with gestational age between 15 weeks and 19 weeks+6 receiving prenatal screening in Xiaoshan Hospital during May 2014 and May 2015 were collected. BPDs were used to establish a localized BPD-gestational age formula. The localized formula was used to evaluate the prenatal screening risks in 1759 pregnant women with irregular menstrual cycles or uncertain last menstrual period (LMP) in Xiaoshan District, and the results were compared with those calculated using formula in LifeCycle 4.0.With localized formula, the total positive rate of Down syndrome, trisomy 18 syndrome and deformity of neural tube was decreased from 6.96% to 5.85% (<0.05), in which the positive rate of Down syndrome decreased (<0.05), that of deformity of neural tube increased (<0.05), and that of trisomy 18 syndrome remained the same (>0.05). The median MoMs of free-hCG β and α-fetoprotein calculated using localized formula were significantly different from those calculated using the formula in LifeCycle 4.0 (all<0.05), and the former ones were more closer to 1. For women of fetus diagnosed with the above diseases, the positive rate calculated using localized formula was almost the same as that calculated using the formula in LifeCycle 4.0.BPD-gestational age formula should be localized based on the statistical analysis of the local population, which will help to reduce the false positive rate, and make the results more accurate and reliable in prenatal screening.

Objective To discuss experiences in reconstruction of severe tibial shaft fractures by using different flaps and external fixations.Methods The study involved 190 patients with type GustiloⅢB Ⅲ C (160 patients) and GustiloⅢC (30 patients) tibial shaft fractures treated from 1990 to 2007.There were 169 males and 21 females,at average age of 42.5 years.The injury causes included traffic accidents in 132 patients,machine accidents in 32 and stone smashing in 26.The management procedure consisted of administration of antibiotics,serial debridement and different flap grafting (including free thoracoumbilical flaps in 20 patients,sural neurocutaneous vascular flaps in 108,saphenous neurocutane ous vascular flaps in 12,superficial peroneal neurocutaneous flap in two,fasciocutaneous flaps in 26 and gastrocnemius muscular flaps in 22) and different external fixators (half-ring fixators in 84 patients,unilateral axial dynamic fixators in 12,AO fixators in 10,Weifang fixators in 42 and hybrid fixators in 40).The average follow-up was 7.3 years.Results All flaps survived.Of all,186 patients obtained fracture healing,with mean fracture healing time varying in different patients treated with different external fixators:7.5 months for 84 patients treated with half-ring fixators,11.2 months for eight with unilateral axial dynamic fixators,8.5 months for 12 with AO fixators ,8.1 months for 42 with Weifang fixators and 7.8 months for 40 with assembly fixators.Except for half-ring fixation,the other fixators needed necessary bone graft.Four patients treated with unilateral axial dynamic fixators resulted in nonunion due to osteo myelitis.The latest follow up showed that the function of the ankle and knee was normal,with no pain.Conclusion Combination of half-ring external fixators with various flaps provides good method for treatment of Gustilo ⅢB and ⅢC tibial shaft fractures.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with a rare non-deletional hemoglobin H disease (Hb H disease). METHODS: Peripheral venous blood samples of the proband and his parents were collected and subjected to routine blood testing, hemoglobin electrophoresis and screening for common mutations associated with thalassemia. Next generation sequencing was carried out to detect potential pathogenic variant, and candidate variant was verified by Sanger sequencing. RESULTS: The proband was found to harbor a rare HbA2: c272_279delAGCTTCGG variant, which compounded with southeast Asian type deletion of α-thalassemia (--^SEA). The two mutations were respectively inherited from his mother and father. CONCLUSION The rare HbA2: c.272_279delAGCTTCGG variant compounded with southeast Asian type α-thalassemia (--^SEA) probably underlay the non-deletion Hb H in the proband. Above finding has enabled genetic counseling and prenatal diagnosis for this family.

Objective: To determine the effects of ginsenoside rg3 on the body weight of C57BL/6J obese mice and to investigate its underlying weight loss mechanisms with a focus on white fat browning-related factors. Methods: Eight-week-old C57BL/6J male mice were fed a high-fat diet for 12 successive weeks to construct the obese model. C57BL/6J male mice were fed a standard chow diet to construct normal control group. After 8 weeks of intervention with ginsenoside rg3, the food intake, body weight, body fat mass, blood sugar, and lipid profiles of the mice in each group were detected. Hematoxylin and eosin (HE) staining was used to observe the histological morphology of the adipose tissues. Real-time poly-merase chain reaction (RT-PCR) and Western blotting (WB) were applied to detect the gene and protein expression levels of peroxisome proliferators-activated receptor gama (PPARγ), Peroxisome proliferator-activated receptor-gamma coactivator -1alpha (PGC-1α), PR domain containing 16 (PRDM16), and uncoupling protein 1 (UCP-1).Results: Compared to normal control group mice, the body weight, food intake, body fat composition, and blood lipid levels of model group mice increased significantly. After 8 weeks of intervention with ginsenoside rg3, body weight, body fat composition, food intake, and blood lipid profiles decreased. HE staining showed that ginsenoside rg3 can improve white adipocyte hypertrophy to a certain extent. RT-PCR and WB demonstrated that ginsenoside rg3 can increase the mRNA and protein expression levels of PPARγ, PGC-1α, PRDM16, and UCP-1 in the adipose tissues of obese mice. Conclusion: The weight reduction effect of ginsenoside rg3 may be related to the promotion of white fat browning.

Objective To observe the effects of acupuncture at acupoints along the meridians on the expression of frontal lobe associated protein kinase in pchlorophenylalanine(PCPA)induced insomnia rats;To explore the mechanism of acupuncture in improving insomnia.Methods Totally 60 rats were randomly divided into blank group,model group,sham acupuncture group,acupuncture group and Western medicine group,with 12 rats in each group.An insomnia model rat was induced by intraperitoneal injection of PCPA.The acupuncture group received acupuncture at"Baihui","Shenmen"(bilateral),and"Sanyinjiao"(bilateral),while the sham acupuncture group only fixed the needle at the corresponding acupoints but did not penetrate the skin,while the model group was only fixed for 30 minutes,the Western medicine group was given a solution of estazolam by gavage for 7 consecutive days,the blank group was not treated.The pentobarbital sodium reversal experiment was used to detect the sleep latency and sleep time of rats,ELISA was used to detect the content of melatonin(MT)in plasma,RT-PCR was used to detect the mRNA expressions of calmodulin dependent protein kinase(CaMK)Ⅱ,protein kinase C(PKC)and p38 mitogen activated protein kinase(MAPK)in frontal lobe tissue,and Western blot was used to detect the protein expressions of CaMKⅡ,PKC and p38MAPK in frontal lobe tissue.Results Compared with the blank group,the sleep latency of the model group rats were significantly prolonged and the sleep time were significantly shortened(P<0.01),the content of MT in plasma was significantly reduced(P<0.01),and the mRNA and protein expressions of CaMKⅡ and PKC in frontal lobe tissue were significantly decreased(P<0.01),the mRNA and protein expressions of p38MAPK were significantly increased(P<0.01).Compared with the model group,the sleep latency were significantly shortened and the sleep time were significantly prolonged in the acupuncture group and the Western medicine group(P<0.01),the plasma MT content significantly increased(P<0.01),the mRNA and protein expressions of CaMKⅡ and PKC in frontal lobe tissue significantly increased(P<0.05),and the mRNA and protein expression of p38MAPK significantly decreased(P<0.01).Compared with the sham acupuncture group,the sleep latency shortened and sleep time were significantly prolonged in the acupuncture group and the Western medicine group(P<0.01),plasma MT content significantly increased(P<0.01),PKC mRNA expression in frontal lobe tissue significantly increased(P<0.01),and p38MAPK mRNA expression significantly decreased(P<0.01).There was no statistically difference in various indicators between the acupuncture group and the Western medicine group(P>0.05).Conclusion Acupuncture at acupoints along the meridians can shorten the sleep latency and prolong sleep time,improve sleep status by regulating the expression of associated protein kinase in frontal lobe of insomnia rats.
