OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.
METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.
RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.
CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.
METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).
RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.
CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

OBJECTIVETo observe the pregnancy outcome among patients with chronic myelogenous leukemia (CML) treated with tyrosine kinase inhibitors (TKIs).
METHODSData associated with pregnancy, delivery and neonate from the patients or patient's spouse who conceived while receiving TKIs were collected retrospectively.
RESULTSTwo young female patients (who had been on imatinib therapy for 90 and 91 months, respectively) and spouses of 10 male patients (involving 7 patients who had received imatinib for a median of 60 months and 3 who had received dasatinib for 2.5 months to 7 months, respectively) with median age of 33.5 years (range 26 - 46 years) conceived and gave birth to 12 babies. One woman took imatinib throughout her pregnancy except one month. The other one took imatinib throughout her pregnancy and had breast-fed while on imatinib therapy for nearly half a year postpartum. Among the 12 babies, one was born prematurely with low birth weight and hypospadias (surgical repair after birth), the others were all healthy with no congenital defects. The median age of the children at the date of this report is 17.5 months (range 3 to 101 months), and they all have a normal pattern of growth and development.
CONCLUSIONSConception among patients with CML while receiving TKIs may result in normal pregnancies. The possible effects of TKIs on birth abnormalities cannot be ruled out. It is recommended that childbearing female patients should be advised to practice adequate methods of contraception and should not breast-feed while on TKIs therapy. In cases of accidental pregnancy, risk/benefit evaluations must be carried out carefully on an individual basis. No special precautions apply for male patients being treated with imatinib.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.

The morbidity and mortality of cardiovascular diseases are increasing year by year.However,the current treatment is still not enough to solve the problem.As an important second messenger,Ca2+ homeostasis disequilibrium would lead to cellular dysfunction and metabolic disorder,which is the leading cause of cardiac function abnormalities,such as cardiac hypertrophy,atrial fibrillation,myocardial ischemia and heart failure.The ryanodine receptor 2 (RyR2),L-type calcium channel,Na +-Ca2+ exchanger (NCX) and sarcoplasmic reticulum Ca2+ ATPase -2a (SERCA2a) involve in maintaining calcium homeostasis.Unfortunately,the exact regulatory mechanism is not fully understood,leading to the limitations of its application in the treatment and prevention of heart disease.Noncoding ribonu-cleic acids (ncRNA) are a group of ribonucleic acid (RNA) molecules that could not be translated,which participate in a variety of biological functions.Clarifying the mechanism of ncRNAs in Ca2+ homeostasis will contribute to determine the susceptibility to cardiac disease,such as atrial fibrillation,halt the progression of diseases and improve the prognosis of patients.This paper reviewed the research progress on ncRNAs in Ca2+ homeostasis regulation.

Objective:To find the relationship between insulin-resistance and Syndrome Differentiation type (SDT) in hypertensive patients.Methods: Two hundred and nine patients of early stage hypertention with no complications of heart, brain or kidney were selected and classified into 4 types according to SDT, the Liver-Fire exuberant type (A), the Phlegm-Dampness abundant type (B), the Yin-Deficiency and Yang-Excess type (C) and the Deficiency of both Yin and Yang type (D). Their insulin sensitivity was examined and compared with that of 40 healthy subjects.Results:(1) Compared with the healthy subjects, all hypertensive patients had apparent insulin resistance (P<0.05).If the insulin sensitivity of healthy subjects was defined as 1.00, that of patients of type A, B, C and D were 0.54, 0.58, 0.65 and 0.80 respectively. (2) The insulin sensitivity of patients in the 4 SDT groups were compared and no significant difference was found in comparison between group A, B and C, while significant difference was found when the other three groups were compared with group D (P<0.05), the insulin sensitivity of type D was close to that of the healthy subjects. (3) The fasting blood insulin of type D was obviously lower and the insulin sensitivity of type D was obviously higher than that of the other three types as a whole (P=0.0001). (4) Multivariate regression analysis demonstrated that insulin sensitivity was closely correlated with SDT (P=0.0001). Conclusion: Insulin resistance is one of the pathological basis for SDT in hypertension.
