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.

A simple and cost-effective indirect competitive enzyme-linked immune sorbent assay (ic-ELISA) was developed to rapidly screen the content of aflatoxin B1 (AFB1) in lotus seeds, and the results were confirmed by ultra-fast liquid chromatography-tandem mass spectrometry( UFLC-MS/MS). Matrix-matched calibration expressed a good linearity ranging from 0. 171 to 7. 25 µg · L(-1) for AFB, with R2 > 0.978. The medium inhibitory concentration( IC50 ) for AFB1 was 1.29 µg · L(-1), the recovery for AFB1 was 74.73% to 126.9% with RSD < 5%, and the limit of detection (IC10) was 0.128 µg · L(-1). The developed ic-ELSIA method was applied to rapid analysis of AFB, in 20 lotus seeds samples and the results indicated that the contents of AFB, in samples 1-15 were in the range of 1. 19- 115. 3 µg · kg(-1) and in 40% of the samples exceeded the legal limit(5 µg · kg(-1)), while the contamination rate of AFB, in samples 16-20 was 40%. Pearson correlation coefficient(r) reached 0.997 for AFB1 content in the samples detected by ic-ELSIA and UFLC-MS/MS methods. The results proved that the developed ic-ELISA method is simple, sensitive and reliable, and can be used for rapid and high-throughput screening of AFB1 in lotus seeds

OBJECTIVESTo investigate incidence of perioperative cardiovascular events, to analyze related risk factors for the patients undergoing intraperitoneal surgery.

METHODSThe data of 1079 patients who underwent intraperitoneal surgery (exclude laparoscope surgery) from July 2007 to June 2008 was reviewed and analyzed.

RESULTSFor the patients undergoing intraperitoneal surgery, the incidence of major cardiovascular events was 3.99% (43/1079), all-cause mortality was 1.58% (17/1079). The independent risk factors of major cardiovascular events were age ≥ 60 years, history of coronary heart disease, cardiac insufficiency, arrhythmia, chronic obstructive pulmonary disease, estimated glomerular filtration rate (eGFR) < 60 ml/(min·1.73 m(2)), emergency surgery and duration of surgery > 2.82 h (OR = 2.68 to 5.19, P = 0.001 to 0.031).

CONCLUSIONSThe cardiac risk of intraperitoneal surgery is 3.99%. The risk of cardiac complications should be evaluated in elderly patients and those with ischaemic heart disease, chronic obstructive pulmonary disease, and renal disease, more specifically, when emergent or long duration major surgeries are needed.

OBJECTIVETo study the expression level and intracellular localization of APOBEC3G in peripheral blood mononuclear cells (PBMCs) and liver tissues of chronic HBV patients.

METHODSThe expression level and intracellular localization of APOBEC3G in PBMCs and liver tissues were detected using the western blot and confocal laser scanning microscope (CLSM).

RESULTSWestern-blot showed that the expression level of APOBEC3G in PBMCs of healthy controls was very low. The relative expression levels of APOBEC3G in PBMC of patients with chronic hepatitis B, chronic severe hepatitis, liver cirrhosis, or liver cancer were 4.12+/-0.21, 4.07+/-0.28, 4.16+/-0.36 or 4.21+/-0.39 respectively, which were higher than that in the healthy controls. However, there was no significant difference in APOBEC3G expression among different chronic HBV patients (q = 0.931, 0.744, 1.675, 1.675, 2.606 or 0.931, respectively, all P values more than 0.05). In addition, there was no significant difference on APOBEC3G in liver tissues between chronic hepatitis B patients and hepatocellular carcinoma patients (4.40+/-0.34 vs 4.34+/-0.43, q = 0.588, P more than 0.05). CLSM indicated that the localization of APOBEC3G protein was in cytoplasm of PBMCs and hepatocytes.

CONCLUSIONAPOBEC3G is upregulated in the PBMCs of chronic hepatitis B patients.

OBJECTIVEWe investigated the in vivo effects of recombinant adenovirus-associated virus type-2 (AAV-2) mediated interleukin-10 (IL-10) gene transfer on the expression of matrix metalloproteinase (MMP)-2, 9, tissue inhibitor of metalloproteinase (TIMP)-1, collagen type I and type III in a rat acute myocardial infarction model.

METHODMale Sprague-Dawley (SD) rats were randomly divided into three groups (each n = 6): sham operation group, MI/AAV2 group, and MI/AAV2-IL-10 group (10(10) vg/ml x 0.1 ml injection at peri-infarct regions immediately post MI). Five days later, the expressions of MMP-2 and MMP-9 were measured by RT-PCR, Western blot and zymography. The expression of TIMP-1 was measured by RT-PCR and Western blot. Collagen type I and type III were assessed by RT-PCR and immunohistochemical stain.

RESULTSThe myocardial expressions of MMP-2, MMP-9 and collagen contents in MI/AAV2 group were significantly increased than those in sham operation group. Myocardial expressions of MMP-2, MMP-9 were significantly decreased and the expression of TIMP-1 significantly increased in the MI/AAV2-IL-10 group than those in MI/AAV2 group. Moreover, the expressions of collagen type I, collagen type III and the ratio of I/III collagen in border zones of infarcted myocardium were decreased by 47.6% (P < 0.01), 23.6% (P < 0.05), and 17.9% (P < 0.05) respectively, while the expression of TIMP-1 increased by 73.1%(P < 0.05) in MI/AAV2-IL-10 group compared to MI/AAV2 group.

CONCLUSIONIn vivo myocardial IL-10 transfer reduced myocardial MMP and collagen expression and increasing the TIMP expression.

Objective To investigate the characteristics and distribution of human eehinococcosis in Hobukesar Mongolian Autonomous County (HMAC) in Xinjiang. Methods Using cluster sampling methods, the 2 counties (Tiebukenwusa and Narenhebuke) in HMAC were chosen as focusing areas for investigation. A survey of human echinococcosis including questionnaire, serological test and abdominal ultrasonic scan was carried out. Results The prevalence of human echinococcosis was 9.0% (64/712) by ultrasound and surgical history, including 8.7% (62/712) for cystic eehinococcosis(CE), 0.3%(2/712) for alveolar echinococcosis(AE) and 15.6%(111/712) for total of serological positives in HMAC. CE prevalence rate of different occupations, age, family slaughtering livestock and drinking water source had significant differences(P<0.05). Herdsmen as the highest risk group showed a CE prevalence of the 13.4% (27/201) in comparison with other occupations. The ages between 20 to<40 year-old were at the highest risk stage with 12.8% incidence. But CE prevalence rate of different gender, ethnic and education groups had not significant differences(P>0.05). Conclusions HMAC could be considered as a high endemic human CE region in Xinjiang. The current study reported the main risk factors may include occupations, age difference and drinking water source.

ITS2 sequence was used as a barcode to identify herbal tea ingredient Plumeria rubra and its adulterants. Genomic DNAs from forty eight samples were extracted, the ITS2 sequences were amplified and sequenced bi-direstionlly, and then assembled and obtained using CodonCode Aligner. The sequences were aligned using ClustalW, the genetic distances were computed by kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic trees were constructed using MEGA5.0. Results showed that the length of ITS2 sequence of P. rubra were 244 bp. The intra-specific genetic distances (0-0. 016 6) were much smaller than inter-specific ones between P. rubra and its adulterants(0.320 8-0.650 4). The NJ tree indicated that P. rubra and its adulterants could be distinguished clearly. Therefore, Using ITS2 barcode can accurately andeffectively distinguish herbal tea ingredient P. rubra from its adulterants, which providesa new molecular method to identify P. rubra and ensure its safety in use.

OBJECTIVETo observe the expressions of human beta-defensin 1 and 2 (hBD-1 and hBD-2) in nasal mucosa before and after the endoscopic sinus surgery and investigate the effects of hBD-1 and hBD-2 on the healing process after the surgery.

METHODSThe patients undergoing endoscopic sinus surgery for chronic sinusitis were divided into 3 groups according to the response to the surgery, namely cured group, response group and non-response group. With those from healthy control subjects as the control, nasal mucosa samples were collected from the patients at 1 week, 2 weeks, 1 month, 3 months and 6 months after the surgery for detection of hBD-1 and hBD-2 mRNA and protein expressions by RT-PCR and Western blotting.

RESULTShBD-1 and hBD-2 were expressed in both normal and chronic sinusitis mucosa, but the expression levels varied significantly between the individuals. The expression levels of hBD-2 was significantly correlated to the patients' response to the surgical treatment (P<0.05). hBD-1 showed slight differences between the individuals, but was not associated with the patients' prognosis.

CONCLUSIONThe expressions of hBD-2 mRNA and protein are significantly increased in patients with good response to endoscopic sinus surgery for chronic sinusitis, suggesting the value of hBD-2 as an indicator of the patients' prognosis.
