OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

Objective To analyze the risk factors of retinopathy and nephropathy in hospitalized patients with type 2 diabetics. Methods 24 h-urinary albumin was measured in 2 338 patients with type 2 diabetic hospitalized from July, 2002 to Sep, 2008 in our hospital. All the subjects were divided into normalbuminuria group (NA) and diabetic nephropathy group (DN), the latter consisted of microalbuminuria group (MAU) and macroalbuminuria group (CAU). All the patients were divided into normal retina group (NR) and diabetic retinopathy group (DR), the latter consisted of background diabetic retinopathy group (BDR) and proliferative diabetic retinopathy group (PDR) according to fundus photography. Results (1) The percentages of DR and DN of this cohort were 28.8% and 28.7%, respectively.The percentage of DR and DN had no statistical difference between male and female (27.8% vs 30.0%;29.6% vs 27.6%, P>0.05). (2) The percentage of DR was 23.1%, 37.7% and 56.6% in NA, MAU and CAU group, respectively. There was significant difference among different albuminuria group (P<0.01). (3) The percentage of DN was 23.1%, 41.1% and 59.3% in NR, BDR and PDR group, respectively. There was significant difference among different DR group (P<0.01). (4) Combined with DN, diabetes duration, systolic pressure, hemoglobin A1C, triglyceride were independently associated with DR by Logistic regression analysis. Meanwhile, combined with DR, systolic pressure, hemoglobin A1C, and triglyceride were all independently associated with DN. Conclusions The onset and progression of microvascular complications in type 2 diabetic patiens are correlated with hemoglobin A1C and systolic pressure. Diabetic retinopathy is closely correlated with diabetic nephropathy.

Pathological cardiac hypertrophy is a maladaptive response in a variety of organic heart disease(OHD),which is characterized by mitochondrial dysfunction that results from disturbed energy metabolism. SIRT3, a mitochondria-localized sirtuin, regulates global mitochondrial lysine acetylation and preserves mitochondrial function. However, the mechanisms by which SIRT3 regulates cardiac hypertrophy remains to be further elucidated. In this study, we firstly demonstrated that expression of SIRT3 was decreased in AngiotensionⅡ(AngⅡ)-treated cardiomyocytes and in hearts of AngⅡ-induced cardiac hypertrophic mice. In addition, SIRT3 overexpression protected myocytes from hypertrophy, whereas SIRT3 silencing exacerbated Ang II-induced cardiomyocyte hypertrophy.In particular,SIRT3-KO mice exhibited significant cardiac hypertrophy. Mechanistically, we identified NMNAT3 (nicotinamide mononucleotide adenylyltransferase 3), the rate-limiting enzyme for mitochondrial NAD biosynthesis, as a new target and binding partner of SIRT3.Specifically,SIRT3 physically interacts with and deacety-lates NMNAT3,thereby enhancing the enzyme activity of NMNAT3 and contributing to SIRT3-mediated anti-hypertrophic effects.Moreover,NMNAT3 regulates the activity of SIRT3 via synthesis of mitochon-dria NAD.Taken together,these findings provide mechanistic insights into the negative regulatory role of SIRT3 in cardiac hypertrophy.Sirtuin 3(SIRT3),a mitochondrial deacetylase that may play an impor-tant role in regulating cardiac function and a potential target for CHF

OBJECTIVETo investigate the phenotypic characteristics of human fetal liver cells (FLCs) and to obtain the homogenous hepatic progenitors with cloning.

METHODSImmunofluorescence and flow cytometry were used to determine the phenotypes of the FLCs. The proliferating colonies were isolated using clone ring in different culture conditions. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to determine the mRNA expression after further cultivation.

RESULTSThe cultured FLCs showed a non-typical epithelial morphology. The positive rate for hepatic cell specific markers alpha-fetoprotein (AFP), albumin (Alb), cytokeratin 8 (CK8) and CK19 were approximately 28.1%, 84.7%, 55.1% and 9.1% respectively. Furthermore, the FLCs expressed the hematopoietic stem cell markers CD34 and CD45 with percentages of 0.04% and 0.09%. 71.8% and 75.3% of the FLCs were positive for the mesenchymal cell marker CD105 and CD166. Most of the colonies showed an elongated morphology, some with an unregular spreading-out morphology, only a small number of colonies with an epithelial-like morphology. RT-PCR results showed that among the 19 colonies obtained after further cultivation and the percentages of epithelial cell adhesion molecule (EpCAM), AFP, Alb and CK19 were 52.6%, 21.1%, 52.6% and 84.2%, respectively.

CONCLUSIONSThe clonal culture system is beneficial to obtain the homogenous hepatic progenitor cells from the heterogeneous culture of FLCs.
