Treating different diseases with the same method is a unique original thinking in Chinese medicine, which embodies the spirit of treatment based on syndrome differentiation. We briefly reviewed the origin and development of this concept. We also reviewed that thinking of combination of disease and syndrome is its premise and foundation. We put forward the conditionality of diseases in treating different diseases with the same method by cutting-in modern biological basic researches, that is to say, one kind specific diseases or disease of one specific system. We emphasized the importance of diseases conditionality in treating different diseases with the same method, which was of great significance in studies on combination of disease and syndrome, correspondence of prescription and syndrome, and modern biological basic researches of treating different diseases with the same method.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

OBJECTIVETo explore the effects of trichloroethylene (TCE) on cardiac developmental differentiation in human embryonic stem cells.

METHODSIn this study, based on the human embryonic stem cells in vitro cardiac differentiation assay, we investigated the potential effect of TCE exposure on the cardiac toxicity in embryo development. Human embryonic stem cells were treated with TCE at different concentrations of 100 ppb, 1 ppm, and 10 ppm and dimethyl sulfoxide(DMSO) treated as control. The MTT assay was performed to examine the cytoplasmic toxicity of TCE exposure. The beating percentages were recorded and the expression of cardiac specific gene was evaluated by PCR or flow cytometry. Also, real time PCR was performed to verify the micro array analysis on the expression level changes of genes which were involved in the Ca2+ signal pathways.

RESULTSCompared with the control group, there was no significant difference in cell viability when cells were treated with TCE at the concentrations of 100 ppb, 1 ppm, and 10 ppm. However, TCE could inhibit the expression of cTnT protein in a concentration-dependant manner. And the most interestingly, TCE significantly inhibited the cardiac differentiation characterized by the decrease beating percentages. Genes involved in Ca2+ signaling pathway were severely disrupted by TCE.

CONCLUSIONTCE inhibited the cardiac specific differentiation of human embryonic stem cell and at the meanwhile the genes responsible for Ca2+ signaling pathway were severely disrupted, which could contribute the severe effects of TCE cardiotoxicity.

Objective To assess the left ventricular (LV) systolic synchrony in patients with myocardial infarction using real-time three dimensional echocardiography(RT-3DE) and speckle tracking imaging(STI). Methods Twenty-five healthy subjects and thirty patients with myocardial infarction underwent two-dimensional echocardiography and RT-3DE examination. The systolic synchrony parameters derived from RT-3DE were the dispersion of time and the maximum difference of time to minimum regional volume for 16 LV segments (Tmsv-16-SD and Tmsv-16-Dif). When the Tmsv-16-SD was above the percent 99 of the control group distribution in patients with myocardial infarction were considered statistically different from those in the control group and were accordingly classified as LV systolic asynchrony. The time from the onset of QRS complexes to systole peak strain from the radial vectors was recorded using STI. The standard deviation and the maximal temporal difference of the radial (TRS-SD and TRS-Dif) of 18 segments were calculated as indicator of LV systolic synchrony. LV systolic asynchrony was defined as an interval≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Results All the systolic synchrony parameters derived from RT-3DE and STI were significantly larger in the myocardial infarction group than those of the control group (all P＜0.01 ).For Tmsv-16-SD and Tmsv-16-Dif,a moderate correlation with TRS-SD and TRS-Dif( r = 0.675 and 0.620,all P＜0.01) was found. No significant difference and general consistency were found between the systolic asynchrony parameters by RT-3DE and STI ( P = 0.125, Kappa = 0.60). Conclusions RT-3DE and STI provide effective tools to assess the LV systolic synchrony. There is no obvious correlation between these methods, thus it is essential of using different methods and parameters to evaluate the LV systolic synchrony.

This study aimed to investigate the drug susceptibility of wild-type and mutant avian influenza A (H7N9) virus neuraminidase (NA) to oseltamivir and zanamivir. Codon optimized DNA of H7N9 (A/ Hangzhou/1/2013) NA was synthesized and constructed into the pcDNA3.1/His vector (NA(H7N9-WT)). Mutant NA(H7N9-H274Y) and NA(H7N9-R292K) plasmids were constructed by directed mutagenesis PCR using NA(H7N9-WT) plasmid as the template followed by sequencing. NA plasmids were transfected into 293T cells and cell lysates containing NAs were collected 48 h post-transfection. Wild-type and mutant NAs were analyzed by Western blotting and their activities were tested by the 4-MUNANA-based assay. All three NAs were expressed and enzymatic activities were confirmed. The effects of oseltamivir and zanamivir on all three NAs were then tested. It showed that the half maximal inhibitory concentrations (IC50s) of oseltamivir carboxylate on NA(H7N9-WT), NA(H7N9-H274Y) and NA(H7N9-R292K) were 1.6 nM, 15.1 nM, and > 1 000 nM with fold changes of 9 and > 625, respectively. The IC50 values of zanamivir on NA(H7N9-WT), NA(H7N9-H274Y), and NA(H7N9-R292K) were 1.1 nM, 1.4 nM, and 38.0 nM with fold changes of 1.3 and 34, respectively. These results indicated that oseltamivir and zanamivir could significantly inhibit NA(H7N9-WT). NA(H7N9-R292K) showed high-level resistance to both drugs (34-fold and 625-fold) and NA(H7N9-H274Y) was sensitive to both (1.3-fold and 9-fold). These results indicated that both oseltamivir and zanamivir could be used for patients infected with the H7N9 virus. However, when patients carried the H7N9 virus with a NA R292K mutation, other medications would be preferred over oseltamivir or zanamivir.

Objective To investigate the role of Treg/CD4~+ T in the pathogenesis and prevention of bowel dysfunction after acute enteritis in rats.Methods Studies were conducted in 40 female Wistar rats with weights of 170-180 g.The rats were divided into normal control,experimental control,antibi- otics-treated,probiotics-treated and combined treated groups.The latter 4 groups were first infected with shigella flexneri by garage to establish the model of acute infectious enteritis,then normal control and experimental control group were administered 1 ml saline once everyday for 10 days.Antibiotics- treated group was given gentamycin 1 ml (8.32 mg?kg~(-)?d~(-1)) for 3 days,then was given saline 1 ml once everyday for 7 days.Probiotics-treated group was given medilac-S 1 ml (52 mg?kg~(-1)?d~(-1)) by gavage for the first 7 days,and 1 ml saline for the latter 3 days.The combined treatment group was given gentamycin for the first 3 days and medilac-S for the latter 7 days using the same dose.All rats were given colon-rectal balloon distention 16 to 22 days after the occurrence of bowel inflammation.The contraction of enteric smooth muscle was measured in vitro,the proportion of Treg cells in blood and mesenteric lymph node were analyzed by flow cytometry,and the histological changes were also observed at the same time.Statistical analyses were performed by using t test or one way ANOVA. Results No obvious changes of distal colon were histological observed in different groups.The perceptual threshold of rat gut decreased and the tension integral of enteric smooth muscle increased,and the ratio of Treg/CD4~+ T in blood and mesenteric lymph node was significantly lower in experimental control group [(4.40?0.43)%;(2.47?1.36)%] than normal controls [(5.15?0.47)%;(4.01?1.12)%,P＜0.05],while that of combined treatment group had no difference from normal controls [(4.95+0.41)%;(3.22?1.86)%].Conclusions The ratio of Treg/CD4~+ T may play an impor- tant role in the pathogenesis of post-infectious bowel dysfunction in animals.Treating acute enteritis with both antibiotics and probiotics can normalize the abnormalities,and thus prevent the occurrence of bowel dysfunction.

OBJECTIVETo explore the effect differences between twirling-rotating reinforcing and reducing technique of acupuncture on cardiac damage in spontaneous hypertensive rats (SHR).

METHODSSixty male 11-week-old SHR were randomly divided into four groups: a model control group (group A), a twirling-rotating reinforcing technique group (group B), a twirling-rotating reducing technique group (group C) and a needle retaining group (group D), 15 rats in each one. In addition, twelve male 11-week-old Wistar rats were used as a blank control group (group E). Acupuncture was not used in group A and group E, only with grasp, capture and binding stimulation that was also adapted in the rest groups. Rats in the group B were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reinforcing technique for 1 min and then the needles were retained for 9 min; rats in the group C were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reducing technique for 1 min and then the needles were retained for 9 min; rats in the group D were treated with acupuncture at "Taichong" (LR 3) but without any technique and then needles were retained for 10 min. Before and after acupuncture, blood pressure monitor was used to measure the rats' systolic pressure and diastolic pressure every 6 days. Twenty-eight days after the treatment, HE and Masson staining were adopted to observe the status of left ventricular hypertrophy and myocardial fibrosis. ELISA method was applied to test the content of endothelin-1 (ET-1). PCR semiquantitative method was used to analyze Type I and III collagen mRNA in the left ventricular.

RESULTS(1) Blood pressure: after the treatment, the systolic pressure and diastolic pressure were both increased in the group A and the group B (P < 0.05); while the two pressures were both lowered in the group C and the group D (P < 0.05), which was more obvious in the group C (P < 0.05). (2) According to HE and Masson staining, except for the group E, the myocardial hypertrophy and fibrosis could be found in the rest groups, in which the group C was the modest, followed by the group D, while the group A and the group B were more severe. (3) Concentration of ET-1: there were differences of concentration of ET-1 among 5 groups (P < 0.05), and the concentration value from high to low was the group A, B, C, D and E. (4) Type I collagen mRNA: the difference of level of Type I collagen mRNA between group C and D was not statistically significant (P > 0.05); compared with the group A and B, the level was lower in the group C; the level was the lowest in the group E. Type III collagen mRNA: the difference between the group A and B was not statistically significant (P > 0.05); compared with the group A, B and D, the level was lower in the group C.

CONCLUSIONThe twirling-rotating reducing could reduce the systolic pressure and diastolic pressure in SHR, effectively prohibit the production of ET-1 and expression of Type I and III collagen mRNA, and it has more obvious inhibiting effect on Type III collagen mRNA. There is biological effect difference between twirling-rotating reinforcing and reducing technique.
