Objective:To study the expression of angiotensin-converting enzyme(ACE),extracellular signal-regulated kinase(ERK),and the changes of atrial fibrosis in patients with rheumatic heart disease(RHD) and atrial fibrillation(AF) treated with angiotensin-converting enzyme inhibitor(ACEI).Methods:Atrial tissues were obtained from the right appendage during open surgery in 35 patients with RHD.The mRNA of ACE and ERK2 were semi-qualified by reverse transcription-ploymerase chain reaction(RT-PCR) and normalized to the glyceraldehyde 3-phosphate dehydrogenase(GAPDH).Western blotting analysis was employed to examine the expressions of ACE and phosphorylated ERK(pERK).Atrial collagen volume fraction(CVF) was detected by Masson's stain.Results:The mRNA of ACE and ERK2 or the protein of ACE and pERK were significantly increased,and CVF was significantly increased in patients with chronic atrial fibrillation(CAF) compared with sinus rhythm group(SR)( P 0.05).Conclusion:The expressions of ACE,ERK2 and pERK increase,and fibrosis is more severe in RHD patients with CAF as compared with those with SR.Compared with CAF patients treated without ACEI,the expressions of ERK2 and pERK significantly decrease( P 0.05)in CAF patients treated with ACEI.This suggests that the increasing expression of ERK2 and pERK resulting from local renal angiotensin-converting enzyme system activation mediates the development of atrial fibrosis,and ACEI may contribute to lesser atrial fibrosis in RHD patients with AF.

According to the sera aquaporin-4 antibody (AQP4), neuromyelitis optica (NMO) can be classified into two types as AQP4 antibody positive (AQP4+) and negative (AQP4-). However, the NMO patients with AQP4- are prone to delayed treatment, and may have a different pathogenesis compared to that in patients with AQP4+. Scientific researches and the clinical trials on NMO with AQP4- will deepen the understanding of NMO pathogenesis and help to make an early accurate diagnosis and rational therapy for NMO with AQP4-. This review aims to summarize the progress in clinic diagnosis for NMO patients with AQP4-.

Pulmonary hypertension (PH) is a progressive disorder characterized by abnormally elevated blood pressure of the pulmonary circulation. PH progresses rapidly to right ventricular (RV) failure and even death without treatment. Cardiac magnetic resonance (CMR) is an accurate and reproducible tool for the assessment of RV morphology and function, which plays an important role in the prognosis of patients with PH. The aim of this study is to review the clinical application and research progress of CMR in evaluation of PH.

The acupuncture medical literature during the Republic of China is divided into four categories, including theoretical literature, acupuncture channels and acupoints drawing literature, translations, and teaching materials and medical cases. It is found that the theoretical literature focuses on inheriting the traditional theories as well as combining traditional Chinese and Western medicine. The drawings are becoming more and more precise, and in these drawing works anatomy begins to appear at that time. Translations are the achievements of communication between TCM and Western medicine, which promote the scientization of acupuncture greatly. Teaching materials are also influenced by Western medicine, presenting a rough frame of modern acupuncture disciplinary system. As important clinic data, medical cases have great clinical value. Overall, acupuncture medical literature during the Republic of China is widely published, which is influenced greatly by the Western medicine and presents a significant tendency of scientization.

Acupuncture scientization was a consensus of most of acupuncture scholars who had long-term perspectives in the 20th century, among them Ms. ZHULian was the important one. Ms. ZHU Lian built a systemic new acupuncture" academic structure in practice and theory aspects. At the same time, as the main architect of Institute of Acupuncture-moxibustion of China Academy of Traditional Chinese Medicine, Ms. ZHU Lian was the first one who began to carry out the acupuncture clinical trail and laboratory experiment in modern way, which meant "acupuncture therapy" was transformed into "acupuncture science" by Ms. ZHULian's endeavor.

Human epidermal growth factor receptor 2(Her-2),which is often over-expressed in 20%-25% of invasive breast cancer patients,is associated with an aggressive tumor phenotype and therefore,a reduced survival rate.As a widely clinically applied Her-2-targeted monoclonal antibody,herceptin,when combined with chemotherapy,significantly increases the survival time of patients without tumors.However,the majority of the cancers that initially respond positively to herceptin begin to counteract against the treatment within just 1 year.This study described several important and well-known mechanisms as well as the updates and advancement in this field.These mechanisms include over-activation of the P13K/AKT pathway,abnormal expression in the EGFR family and their ligands,the masking of the Her-2 receptor,herceptin,activation of PI3K/AKT via an alternative pathway,over-expression of Darpp-32 and t-Darpp.autophagy of tumor cells and over-expression of HSP27,and more.

BACKGROUND: The optimal total hip replacement can be prepared by assembling S-ROM prosthesis individually. OBJECTIVE: To evaluate the short-time effect of S-ROM prosthesis total hip replacement for osteoarthritis secondary to developmental dysplasia of hip. METHODS: Totally 57 adult patients (63 hips) with osteoarthritis secondary to developmental dysplasia of hip treated by S-ROM prosthesis for primary total hip arthroplasty from November 2002 to February 2007 were selected. The preoperative and postoperative Harris score were compared. The prosthesis loosening, fracture and subsidence, bone absorption and fracture were followed-up with radiographic results. RESULTS AND CONCLUSION: All patients were followed up from 6 months to 5 years, mean 3.5 years. One patient suffered temporary common peroneal nerve palsy, and recovered after 4 months. One patient suffered hip dislocation, and recovered after manipulative reduction and traction. There were no complications in the rest patients. The Harris hip score was 70.20-92.10, mean 88.30, which was obvious increased than that of before operation (P < 0.05). No loosening, fracture and subsidence of prosthesis, bone absorption or fracture was observed. The results demonstrated that S-ROM prosthesis total hip replacement can receive an excellent short-time effect in treating osteoarthritis secondary to developmental dysplasia of hip.

Objective To detect the effect ofXuebijing injection on the serum soluble CD40 ligand (soluble CD40 ligand, sCD40L), lipoprotein associated phospholipase A2 (lipoprotein-phospholipase A2, Lp-PLA2) of patients with acute coronary syndrome (ACS).Methods A total of 120 patients with ACS were randomized divided into the control group and treatment group, 60 in each group.The control group received the routine treatment of Western medicine, and the treatment group receivedXuebijing injectionbased on the intervention of control group. Both groups were treated for 2 weeks. ELISA method was used to detect serum sCD40L, Lp-PLA and IL-6, TNF-α and CRP.Results After treatment, the serum sCD40L(320.62 ± 35.81 pg/Lvs. 401.70 ± 4.84 pg/L, t=10.435), Lp-PLA2 (203.62 ± 33.13μg/L vs. 296.45 ± 4.422μg/L,t=12.831) level was significantly lower than those in the control group (P<0.01); The serum CRP (3.10 ± 2.00 mg/Lvs.4.74 ± 2.04 mg/L,t=4.006), IL-6 (2.10 ± 1.20 pg/Lvs.3.14 ± 1.40 pg/L,t=3.781), TNF (2.81 ± 1.50 pg/Lvs. 3.70 ± 1.70 pg/L,t=3.075) level was significantly lower than thosein the control group (P<0.01 orP<0.05). Compared with the control group, the effect rate (68.3%vs. 50.0%,χ2=4.174) of the treatment group was significantly higher (P=0.041).ConclusionXuebijing injection can improve the therapeutic effectof ACS patients, and reduce CD40L, Lp-PLA2 levels.

Objective To evaluate the effect and safety of ultrasound-guided pereutaneous thrombin injection for the treatment of iatrogenic femoral arterial pseudoaneurysm.Methods Thirty patients [6 male,24 female,age range 45-82 years,mean (63 ± 10) years] were found to have pseudoaneurysms confirmed by ultrasound between 1 and 7 days following femoral arterial puncture from July 2011 through July 2014.Results All patient had pseudoaneurysm thrombosis after the first procedure.Thrombin 200-1000 U (50 U/mL)was injected into the pseudoaneurysm under ultrasound-guidance,performed.One patient showed acute allergy 5 min after thrombin injection,which was relieved by anti-allergic therapy.No thromboembolic complications or infections occurred.Conclusions Ultrasound-guided pereutaneous thrombin injection is a safe and effective noninvasive method for the treatment of iatrogenic femoral pseudoaneurysm and should be considered as first-line therapy.
