Endometrial blood flow is directly related to endometrial receptivity thereby affecting in vitro fertilization and embryo transfer (IVF-ET) outcomes. In recent years a growing number of studies have shown that traditional Chinese medicine (TCM) can play a role to improve endometrial blood flow and embryo transfer. Studies have confirmed that formulas based on reinforcing kidney and activating blood can promote the formation of uterine endometrial blood vessels by adjusting expressions of a variety of vessel growth factors, and regulating nitric oxide level for inhibition of vascular smooth muscle contraction of the uterus. Treatments based on differentiation of syndromes are key to the theory of TCM. Differentiation of syndromes should be combined with biomedical disease diagnosis. It is also necessary to further clarify other endometrial blood flow disorders using TCM diagnostic methods. In these cases, drugs for reinforcing kidney and activating blood are relevant, but other medicines for smoothing liver qi and nourishing blood, as well as tonifying the spleen and generating blood may also be effective. Future clinical studies should focus on the observation of different types of TCM syndromes and the research on compatibility ratio and dose-dependent relationship of Chinese medicines. Acupuncture has been used during IVF-ET for more than 10 years. Electro-acupuncture can control the expansion of the uterine arteries by inhibiting the sympathetic nerves. However, acupuncture has not been proved to regulate endometrial arteries. To sum up, TCM can be applied to improve endometrial blood flow so as to increase birth rates in IVF-ET. The combination of Chinese and Western medicines and acupuncture application will increase their combined effect, thereby obtaining greater clinical benefits.

Objective To analyze the new primary mutation in Chinese people with Leber′s hereditary optic neuropathy (LHON). Methods Genomic DNA was collected from 260 suspected LHON patients and 100 normal healthy persons. The mitochondria DNA mutation at nucleotide position (NP) 15257 and the hot spot (14452-14601 bp) of ND6 gene which include the mutations at NP (14482, 14498, 14568, 14596, 14495, and 14459) were screened by using polymerase chain reaction (PCR), heteroduplex-single strand conformation polymorphism (HA-SSCP) and restriction fragment length polymorphism (RFLP) analysis and sequencing. Primary mutation spectrum of Chinese race was analyzed. Results Eight kinds of polymorphism of mitochondria DNA were found in 260 suspected LHON patients and 100 normal healthy persons, including NP 14488C, 14518G, and 14617G which hadn't been reported (http://www.mitomap.org/). No mutation at NP 15257, 14482, 14498, 14568, 14596, 14495, and 14459 was found. Conclusion The NP 15257A may not be the primary mutation in Chinese. Because of the race difference, 14452-14601 bp in ND6 gene may not be the hot spot in Chinese patients with LHON, and other hot spots may exist.

Conclusion:It was reliable that flexible ureteroscope combined with extracorporeal shock wave lithotripsy to treat the kidney stones with a diameter of more than 2cm, lower complication rate, worthy of clinical.

Objective To calculate and measure the depth and radius of the target vessel in the upper limb venous ultrasound image in order to contribute to automatic venipuncture.Methods Two methods of measuring the radius of veins in an ultrasonic vein cross section image were adopted.One method was to segment the vein based on the threshold selected after evaluation, and then scan the upper and lower edges of the vein to obtain the radius.The other method was based on Otsu method,which was to divide the vein and then morphologically process the binary image.The radius was calculated in a manner similar to the first method.After the radius was obtained, the depth of the vein was corrected in conjunction with the radius.Results The above two methods were tested on 500 upper limb venous ultrasound images.The accuracy rate of the first method was 93.0%, and that of the second method was 99.4%.Conclusion The method based on Otsu and morphological processing is more effective for radius measurement of veins in upper limb venous ultrasound image.

Objective To investigate if edema caused by rosiglitazone is associated with the change of aldosterone level. Methods Plasma aldosterone levels in different periods from patients treated with rosiglitazone combined with insulin were measured.Type 2 diabetes patients who have been treated with insulin alone were divided into two groups: patients treated with rosiglitazone(4mg/d) combined with insulin(RSG+insulin group), or treated with insulin alone (insulin group)(n=10). Aldosterone levels, incidence of edema and weight gain were monitored every two months during six months. Results The incidence of edema and weight gain were higher in RSG+insulin group than in insulin group. After two months, aldosterone levels were higher in RSG+insulin group than in insulin group[(77.8±25.9)vs(60.2±27.6)pg/ml,P＞0.05],but it had no statistical difference; after four months, aldosterone levels were higher in RSG+insulin group than in insulin group[(87.2±27.1)vs (61.5±25.6) pg/ml,P＜0.05]. After six months, aldosterone level recovered gradually,it had no statistical difference compared with that of control[(77.0±21.0)vs(69.6±21.7) pg/ml,P＞0.05]. Conclusions The cause of early edema in type 2 diabetic patients treated with rosiglitazone combined with insulin was probably assosiated with elevated aldosterone level.

Objective To build a more perfect serum protein ifngerprint models for early diagnosis of ganglioneuroblas-toma (GNB) in children. Methods Thirty children with GNB and 30 normal control children were recruited. Serum samples were collected. Nonspeciifc serum protein was detected and studied by MB-WCX processing, SELDI-TOF-MS mass spectrom-etry system and MALDI-TOF/TOF platform. Results Through the SELDL-TOX-MS processing, a peak at 5920 m/z protein markers, and the expression of the markers was high in GNB children (6180.6±2328), compared with normal control children (419.1±493.3), the difference was statistically signiifcant (P<0.05);MALDI-TOF/TOF platform showed that the protein with a peak at 5920 m/z is identiifed as ApoC-Ⅲ. Conclusions m/z peak of 5920 protein is suggested as speciifc biomarker of GNB in children, can provide signiifcant reference for early diagnosis of ganglioneuroblastoma, and prognostic monitoring.

Exercise is one of the important techniques of cardiovascular rehabilitation. Exercise can reduce inflammatory response to improve endothelial function, and improve mitochondrial function to increase myocardial cell activity. For cardiovascular risk factors, exer-cise can promote the activity of lipoprotein, increase the level of high-density lipoprotein;improve the function of insulin receptor to reduce insulin resistance, reduce platelet aggregation and improve endothelial function to reduce blood pressure. For the respiratory system, aerobic exercise can improve the function of respiratory muscle, thus relieve the dyspnea. Exercise can promote the activation of immune factor and increase metabolism, to increase immune function and anti-aging. Resistance exercise can improve mitochondrial function and promote fi-ber type conversion, to improve the function of skeletal muscle system.
