OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.

METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.

RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).

CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

Imatinib mesylate has been commonly used in the treatment of patients with chronic myeloid leukemia (CML). However, a significant number of CML patients treated with imatinib developed thrombocytopenia. Platelet-derived growth factor (PDGF)/platelet-derived growth factor receptor (PDGFR) plays a significant role in the regulation of thrombopoiesis. It is suggested that imatinib may block the PDGF/PDGFR and PI3-K/Akt pathway, then inducing the apoptosis of megakaryocytes and developing thrombocytopenia in these patients. In this review, the potential molecular mechanism of imatinib-induced thrombocytopenia in the treatment of CML patients is discussed, including imatinib and thrombocytopenia, PDGF/PDGFR and thrombopoiesis, potential mechanism of imatinib-induced thrombocytopenia in treatment of patients with CML and so on.

OBJECTIVETo detect potential mutation in a Chinese family affected with succinic semialdehyde dehydrogenase deficiency.

METHODSGenomic DNA was extracted from the peripheral blood samples of the proband, her family members and 100 healthy controls. All exons and flanking intronic regions of the ALDH5A1 gene were amplified by PCR and subjected to direct sequencing.

RESULTSThe proband was found to have compound heterozygous mutations of the ALDH5A1 gene, namely c.398_399delAA (p.N134X) and c.638G>T (p.R213L), for which her parents were both heterozygous carriers. The same mutations were not found among the 100 healthy controls.

CONCLUSIONThe novel mutations of the ALDH5A1 gene probably underlie the pathogenesis of the disease in the infant, which also enriched the mutation spectrum of the ALDH5A1 gene.

OBJECTIVETo evaluate the relationship between plasma trough level of imatinib and clinical outcomes in Chinese CML patients.

METHODSPlasma trough levels in 416 CML patients who received imatinib orally in six general hospitals were assessed. The correlations of imatinib plasma trough level with baseline characteristics including age, weight and BSA, and clinical response were evaluated.

RESULTS(1) Effects of age, body weight and BSA on imatinib plasma trough levels were not to be clinically significant. (2) Median imatinib plasma trough levels was 1271 (109-4329). Imatinib plasma trough level was related to dose of imatinib administration. Plasma trough levels at imatinib of dose < 400, 400 and > 400 mg were (969 ± 585), (1341 ± 595) and (1740 ± 748) µg/L (P < 0.01), respectively. (3) There was no statistic difference in imatinib plasma trough level with complete cytogenetic response [CCyR (1337 ± 571) µg/L vs no CCyR (1354 ± 689) µg/L, P = 0.255]. (4) Imatinib plasma trough level might be important for a good clinical response in some CML patients.

CONCLUSIONThere was a large interpatient variability in imatinib plasma concentration in Chinese CML patients. No correlation of imatinib plasma trough level with CCyR was observed. However, higher doses of imatinib were shown to attain greater trough plasma concentration, suggesting that imatinib plasma trough level might be important for a good clinical response in some CML patients.

OBJECTIVETo observe the effects of repeated electroacupuncture (EA) of Zusanli (ST36)- Yanglingquan (GB34) on hypothalamic acetylcholinesterase (AchE) and vesicular acetylcholine (ACh) transporter (VAChT) activities and choline acetyltransferase (ChAT) mRNA and muscarinic M1 receptor (M1R) mRNA expression in chronic constrictive injury (CCI) and/or ovariectomy (OVX) rats so as to reveal its underlying mechanism in cumulative analgesia.

METHODSA total of 103 female Wistar rats were randomly divided into normal control (n =15), CCI (n =15), CCI+EA2d (n =15), CCI+EA2W (n =15), OVX+CCI =13), OVX+CCI+EA2d (n =15), and OVX+CCI+EA2W groups (n =15). CCI model was established by ligature of the unilateral sciatic nerve with surgical suture. Memory impairment model was established by removal of the bilateral ovaries. Morris water test was conducted to evaluate the OVX rats' memory learning ability, and the thermal pain threshold (PT) of the bilateral paws was detected the next morning after EA. EA (2/15 Hz, 1 mA) was applied to bilateral ST36-GB34 for 30 min, once daily for 2 days or 2 weeks, respectively. Hypothalamic AChE activity was detected by histochemistry, VAChT immunoactivity was determined by immunohistochemistry, and ChAT mRNA and M1R mRNA expressions were assayed by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSIn comparison with the normal control group, the AChE activity in hypothalamic arcuate nucleus (ARC) and supraoptic nucleus (SON) regions of CCI group, AChE activity in paraventricular nucleus (PVN), ARC, and SON regions of OVX+CCI group, and hypothalamic muscarinic M1R mRNA expression levels in both CCI and OVX+CCI groups were down-regulated significantly (P <0.05). Compared with the CCI group, the AChE activities in hypothalamic ARC and SON regions of CCI+EA2d and CCI+EA2W groups and PVN region of CCI+EA2W group and hypothalamic ChAT mRNA and M1R mRNA expression levels in CCI+EA2W group were up-regulated considerably (P <0.05). In comparison with the OVX+CCI group, the AChE activities in PVN, ARC, and SON regions and the expressions of hypothalamic ChAT mRNA and VAChT in ARC region of OVX+CCI+EA2W group were up-regulated remarkably (P <0.05). The effects in rats of CCI+EA2W group were evidently superior to those of OVX+CCI+EA2d group in up-regulating AChE activities in PVN, ARC, and SON regions, VAChT immunoactivity in ARC region, and expression levels of hypothalamic ChAT mRNA and M1R mRNA (P <0.05). Similar situations were found in OVX+CCI rats after EA2W. It suggested a cumulative effect after repeated EA of ST36-GB34. Comparison between CCI+EA2W and OVX+CCI+EA2W groups showed that the effects in rats of the former group were evidently better than those of the latter group in up-regulating AChE activity in ARC and SON regions and the expressions of hypothalamic ChAT mRNA and M1 mRNA (P <0.05), suggesting a reduction of EA2W effects after OVX.

CONCLUSIONRepeated EA can significantly up-regulate AChE and VAChT activities and ChAT mRNA and M1R mRNA expressions in the hypothalamus of CCI and OVX+CCI rats, which may contribute to the cumulative analgesic effects of repeated EA and be closely related to the animals' neuromemory ability.

As an important link during the whole operation process of acupuncture, it is very necessary to launch quantity study closely related to acupuncture finger force in the acupuncture quantity study. After retrieval of related literatures on finger force during acupuncture in recent 20 years, it was found out that although some exploration on acupuncture finger force had been made, it was scattered and had no deep research, which pointed out it was a weak link in the acupuncture quantity study. So study of finger force should be paid attention to in acupuncture-moxibustion field, the level of theoretical and experimental research and development of measuring instrument on acupuncture finger force should be strengthened, the application of instrument should be expanded in teaching and scientific research areas, which could promote the modernization and internationalization of acupuncture and moxibustion better and faster.

OBJECTIVETransplantation of adipose-derived stem cells (ADSCs) is associated with potential risks of late complications including tumorigenesis due to the active proliferation of the cells. We aimed to test the effect of transplantation of ADSCs with suppressed proliferation by gamma irradiation in the treatment of thin endometrium in rats.

METHODSADSCs were isolated from female SD rats and identified by detecting the surface antigens with flow cytometry. After exposure to gamma irradiation at 0, 5 Gy and 10 Gy, the cells were examined for changes in colony-forming ability. Twenty-four female rats with chemically induced thin endometrium were randomized into 4 equal groups and at 6-8 h after modeling, the rats received intrauterine injection of non-irradiated ADSCs (group I), 5 Gy irradiated ADSCs (group II), 10 Gy irradiated ADSCs (group III), or PBS only (group IV). Endometrial pathology was analyzed with HE staining in these rats in the third estrus phase following the cell transplantation.

RESULTSThe ADSCs showed a complete loss of proliferative capacity after exposure to 10 Gy irradiation. After the cell transplantation, the endometrium thickness was thicker in group I and II than in group IV (P<0.01), but there was no significant difference between groups III and IV.

CONCLUSIONSGamma irradiation impairs the proliferative capacity of ADSCs in vitro. Exposure to 10 Gy irradiation causes a total loss of proliferation capacity of the ADSCs, which have no therapeutic potential; 5 Gy irradiation causes partial loss of proliferation capacity of the cells, which still retain the activity to promote endometrial cell regeneration.

OBJECTIVESTo study the acupoint specificity through the comprehensive evaluation of the acupuncture effect on rat model with the middle cerebral artery occlusion (MCAO).

METHODSDuplicated MCAO model by Zea-longa's thread ligation was assessed by Zausinger's six-point method, and rats with 1-3 scores were chosen to be grouped. According to the randomized and controlled principle, rats were divided into 6 basic control groups (including normal group, sham group, model control group, model group without intervention, Nimodipine group, lateral-to-Renzhong group) and 6 acupuncture groups [including Neiguan (PC6) group, Weizhong (BL40) group, Chize (LU5) group, Sanyinjiao (SP6) group, Renzhong (DU6) group and non-acupoint group]; in each acupoint or non-acupoint 9 different parameter combinations were respectively set by orthogonal intersection method. There were in total 60 groups, and each group had 12 rats. The rats were treated by acupuncture with the lifting-thrusting manipulation every 12 h, in total 6 times. Indices of neurobehavioral scores, cerebral blood flow, infarction rate, microcirculation, and light microscope, etc. were measured. In order to comprehensively evaluate the acupuncture effect to research the specificity of acupoint, a cluster analysis was made with SPSS17.0 for the comprehensive effect scores of the samples computed according to the comprehensive evaluation models, and then sorting and classification were made for the comprehensive effect scores.

RESULTSIn the acupuncture groups every acupoint had different therapeutic effect due to different acupuncture parameter combinations; among the acupuncture groups the orders of curative effect were as followings: Neiguan group was of exceptional result, Weizhong group and Sanyinjiao group were of valid results in upper level, Chize group and Renzhong group were of valid results in lower level, and non-acupoint group was of invalid result; the therapeutic result of acupoint group was superior to non-acupoint group; and the curative effect of acupuncture group was also superior to basic control group.

CONCLUSIONThe acupoint has the specificity of acupuncture effect, and the acupoint specificity is relative.
