UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

RNA has received more attention in the field of forensic medicine and the development of the new biological markers based on RNA shows great significance in the analysis of complex cases. circular RNA (circRNA) is a kind of non-coding RNA which is widely reported recently. Although the regulatory mechanisms of generation and expression are not fully clear, the existing research indicates that circRNA has important biological functions. CircRNA has a cell-type-specific expression with great stability and a high expression level, which makes it meaningful in forensic applications potentially. In this paper, the research progress, the generation and regulation of circRNA as well as its biological characteristics and functions are summarized, which will provide references for related studies and forensic applications.

To study the telomerase activity in the bone marrow MNCs from patients with myelodysplastic syndromes in comparison with that in normal individuals and acute leukemia patients. The intracellular telomerase activity was semi-quantitatively examined by PCR-ELISA assay in the marrow cells of 20 normal individuals, 21 cases of myelodysplastic syndromes (MDS) and 32 cases of acute leukemia. Telomerase activity in normal marrow cells was 0 - 0.30 U, with a mean level of (0.11 +/- 0.08) U, in which 3 cases were considered positive according to the standard set by the Kit. In 32 acute leukemia patients, the mean level of telomerase activity was (0.42 +/- 0.26) U (ranged 0 - 0.96 U) with a positive rate of 78.1%, showing a significantly higher activity in acute leukemia (P < 0.01). Moderate telomerase activity was detected in 21 cases of MDS, with a mean level of (0.27 +/- 0.19) U (0 - 0.97 U) from which the positive rate was 66.7%. This value was significantly higher than that in the normal BM (P < 0.05). Moreover, a significantly higher telomerase activity was shown in the high-risk group of MDS (P < 0.05). Based on the international scoring system evaluating the prognosis of MDS (IPPS), telomerase activity in HIGH subgroup was significantly higher than that in INT-1 and INT-2 subgroup (P < 0.05). The level of telomerase activity was not correlated to the chromosome aberrations. These results show that a borderline telomerase activity could be found in normal bone marrow cells. Telomerase activity was markedly higher in acute leukemia. BM of MDS patients demonstrated a moderate telomerase activity. Higher telomerase activity could be found in high-risk group and correlated with poor prognosis.

OBJECTIVETo evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) patients of qi-yin deficiency and inter-obstruction between phlegm and stasis.

METHODSAdopting prospective, randomized, controlled trial design, 73 T2DM patients of qi-yin deficiency and inter-obstruction between phlegm and stasis syndrome, were randomly assigned to two groups, the pioglitazone tablet group (36 cases) and the JTXZC group (37 cases). The therapeutic course for all was 8 weeks. The body weight, height, body mass index (BMI), waistline (WC), hipline, waist-to-hip ratio (WHR), and scoring for Chinese medicine (CM) symptoms assessment were observed. The fasting blood glucose (FBG), 2-h postprandial blood glucose (PBG), glycated hemoglobin (HbA1c), plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), plasma insulin (FINS) were detected. The HOMA-IR was also calculated. The safety indices such as liver and renal functions, adverse reactions were also observed.

RESULTSThe levels of HbA1c were lowered after treatment in the two groups after 8 weeks of treatment, showing statistical difference when compared with before treatment (-0.59% +/- 1.99% and -0.27% +/- 2.73%, P < 0.05). The PBG level also decreased with statistical difference (-1.71 +/- 2.52 mmol/L and -0.72 +/- 4.17 mmol/L, P < 0.05), but there was no statistical difference between the two groups. The body weight, BMI, TG obviously decreased (P < 0.05). The CM symptoms efficacy and CM symptom scoring were significantly reduced in the two groups (P < 0.01). Besides, better effects were shown in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the therapeutic course. There was no statistical difference in the incidence of adverse events (P > 0.05).

CONCLUSIONSJTXZC showed similar therapeutic effects to pioglitazone. They both could effectively im- prove clinical symptoms with no severe adverse reaction.

OBJECTIVETo investigate the pathogenesis of globozoospermia, fertilization ability of round-headed sperm, and the application value of assisted oocyte activation in intracytoplasmic sperm injection (ICSI) for the wives of glohozoospermia men.

METHODSWe collected oocytes from the wives of 2 globozoospermia patients and randomly divided them into two groups after ICSI to receive calcium ionophore A23187-activation and conventional treatment, respectively. We reviewed the relevant literature published at home and abroad, and discussed the etiology of globozoospermia, fertilization ability of round-headed sperm, and treatment options for this disease.

RESULTSQuality embryos were obtained in the A23187-activation group while no fertilized oocytes, oocyte cleavage, quality embryos, or blastular formation were found in the conventional treatment group. Both women achieved pregnancy and gave birth to healthy neonates after transfer of the quality embryos from the A23187-activation group.

CONCLUSIONCalcium ionophore A23187 can be applied to ICSI for the wives of globozoospermia men and bring about desirable clinical outcomes. Meanwhile, attention should be paid to its safety.

The apparatus for intrinsic dissolution test recorded in United States Pharmacopeia (USP) integrating with fiber-optic drug dissolution test system (FODT) were used to real-time monitor intrinsic dissolution processes of alliin in four media which were water, solution of HCl with pH 1.2, buffer solution of acetate with pH 4.5, and buffer solution of phosphate with pH 6.8. The intrinsic dissolution rate (IDR) and the similarity factor (f2) of two intrinsic dissolution curves with two apparatuses were calculated. The IDR values of alliin with rotating disk system were 28.1.3, 33.55, 28.38 and 30.95 mg x cm(-2) x min(-1) in four media, respectively. And the IDR values of alliin with stationary disk system were 44.16, 47.07, 45.11 and 51.34 mg x cm(-2) x min(-1), respectively. The similarity factors were 56.42, 50.75, 40.30 and 40.64, respectively. The results showed that the intrinsic alliin dissolution rates were much greater than 1 mg x cm(-2) x min(-1). It inferred that alliin dissolution would not be the rate limiting step to absorption.
