Hydrosalpinx is an important cause of tubal infertility, and main methods of Western Medicine are the surgical symptomatic treatment of hydrops and the assisted reproductive techniques to obtain pregnancy. From the perspective of overall concept and dialectical treatment, Chinese Medicine believes that the basic pathogen of hydrosalpinx infertility is kidney deficiency and blood stasis, kidney deficiency as the basis, and blood stasis as the standard. The disease is located in the uterus, so it is necessary to supplement the kidney and to activate the blood circulation as the treatment method of Chinese Medicine. Chinese Medicine is taken internally and externally, which has a significant effect on improving the clinical symptoms of patients and increasing the pregnancy rate. Modern pharmacology has further confirmed the clear mechanism of the kidney supplement and blood activation of Chinese Medicine. Chinese Medicine has unique advantages in the treatment of hydrosalpinx infertility, which is characterized by the rejuvenation of kidney and blood. The theoretical basis and research progress of kidney supplement and blood activation in the treatment of hydrosalpinx infertility are reviewed. [ABSTRACT FROM AUTHOR]

As a primary tool in climate change research at the watershed scale, the role of horizontal resolution in regional climate simulations needs to be evaluated. This paper investigates the role over the Huang-Huai-Hai (HHH) River basin using a regional climate model, RegCM4, coupled with the National Center for Atmospheric Research (NCAR) Community Land Model, version 4.5 (CLM4.5) including the modules of CN and DV (RCM_CLM4.5). The model is driven by ERA-Interim reanalysis data, and the time period is 1990—2010. Model validation shows that RCM_CLM4. 5 at 50 km and 25 km resolutions can reproduce the present climate well, including the spatial distribution of winter and summer mean temperature and precipitation, the annual cycles of temperature and precipitation, and the climate extremes. However, some biases can also be found. For example, compared with the observation, cold and warm biases are found in the winter and summer mean temperature, respectively; wet biases are found in the precipitation. Comparison between the two simulations, better performance of the magnitude and spatial distribution of mean temperature is found in the simulation at 25 km resolution; while for precipitation, better performance is observed in the one at 50 km resolution; little difference is found for the climate extremes. In general, results from this study indicate a very low sensitivity of present climate in this region to model resolution and can provide a reference for the application of this model in future climate change research over the HHH River basin.

To deal with low correct matching, high time-consuming and high-error in most stitching algorithms, this paper developed an improved image stitching algorithm based on merging match strategies. First, the algorithm extracted SIFT feature points only from the overlap area of pair-image, and computed the SURF descriptors. Second, it merged three match strategies included ratio of the nearest neighbor and the 2nd nearest neighbor distances, cross-check of two directions and pair-matches’ difference threshold method, combined coordinate constraint with RANSAC algorithm to complete the feature match. Finally, it used registration data to calculate the projection model which could transform any image in the sequences to reference image coordinate space, then used multithread technology to accelerate. After the brightness correction, the algorithm used the weighted fusion method to composite panorama images. The experimental results show’ that the proposed algorithm obtains a 10% ~20% correct rate increase in feature match with about 1/3 time-consuming of the traditional frame-to-frame expand stitching algorithm, greatly decreases in accumulated error, and little image distortion.

Objective To propose the confirmatory method for water-a factor related to disease nature. Methods Based on a symptom-pathogenesis database of Chinese medicine，the clinical characteristics of some symptoms that their pathogenesis can and only can be directly explained by water were screened. Results Water maybe excessive and dilute pathological products existing in skin, pleural cavity and abdominal cavity or exhausted from urinary passage and anus because of metabolic disorders. It is related to the decrease of assimilation or re-assimilation of humor. Water, as a factor related to disease nature, has some specific symptoms as (skin) dropsy sunken when pressed，(pleural cavity，abdominal cavity and etc.) hydrops, clear abundant (urine) and watery (stool). Conclusion The evidences for conforming pattern factors are the clinical characteristics of specific symptoms, and pathogenesis explanation is the basis that can establish the close relationship between a pattern factor and clinical characteristics of symptoms. The disease nature can be directly diagnosed as water when any one of above clinical characteristics of specific symptom appears. Water is a pattern factor. [ABSTRACT FROM AUTHOR]

Postpartum hemorrhage is a common severe obstetric complication,and is a major cause of four big maternal death.Tend to occur in 2hours after delivery,bleeding is greater than or equal to 400 ml or postpartum bleeding is greater than or equal to 500 ml after 24 hours,and the incidence rate is 2%to 3% of the total number of delivery.Besides,postpartum hemorrhage is often sudden and ferocious,so if not treated timely,it can directly threaten womens life.Therefore,prevention and control of postpartum hemorrhage are the key to reduce maternal mortality.And the obstetrics and gynecology department of our hospital had receiced and cured 56 patients of postpartum hemorrhage from May 2013 to April 2014,and had discussed the cause of bleeding,andfirst-aid method.
