Objective Onto observe the curative effect of carboprost tromethamine injection combined with mifepristone on the treatment of the patients with risky placenta previa. Methods 66 cases with placenta previa during mid pregnancy from January 2016 to December 2016 in Dingbian county people's hospital were randomly divided into two groups, 33 cases in the control group and 33 cases in the observation group. All patients were received cesarean section and traditional treatments such as oxytocin and gauze filling. Hemostatic effect, prognosis and incidence of adverse reactions in the two groups were compared. Results The intraoperative bleeding volume, the amount of vaginal bleeding 2 hours after operation and the amount of vaginal bleeding 2 to 24 hours after operation in the observation group were less than those in the control group (P<0.05). The rate of postpartum hemorrhage, the rate of disseminated intravascular coagulation and the incidence of puerperal disease in the observation group were significantly less than those in the control group (P<0.05). The sanguinous lochia time and menstrual recovery time in the observation group were better than those in the control group (P<0.05). There was no significant difference in the rate of hysterectomy and adverse reactions between the two groups. Conclusion Carboprost Tromethamine Injection combined with mifepristone in the treatment of pernicious placenta previa can effectively reduce the bleeding rate and promote the rehabilitation of pregnant women. It is safe and has no obvious adverse reactions. It is worthy of clinical application.

So far,the unified definition and diagnostic criteria of feeding intolerance in preterm infants is still unavailable,although they have always been modified and improved.The curative effects of intervention strategies,including the feeding strategies,breast-feeding,medication,and so on,still need multiple clinical randomized studies in order to be verified and evaluated.Therefore,this article will summarize the progress in the definition of feeding intolerance,feeding strategies and medication.

Objective To investigate the effect of borneol on levels of monoamine neurotransmitters in the prefrontal cortex of rat after long-term continuous operations.Methods A rat model of long-term continuous operations were established by using a treadmill protocol.Then Borneol(0.4 g/kg,p.o.) was given to the rats after the operation,and their activity-rest behavior and active avoidance response were assessed.Two h later,the rats were sacrificed and the level of monoamine neurotransmitter in the prefrontal cortex was determined by high performance liquid chromatography combined with electrochemical detection(HPLC-ECD).Results After the administration of borneol,the activities of operational animals were increased markedly as compared with that of vehicle operational group.The operational rats after borneol application had less response time than the ones treated with vehicle(6.85?1.24) s in active avoidance response.The levels of monoamine neurotransmitters including noradrenaline,dopamine,and 5-serotonin in the prefrontal cortex were decreased after treadmill operation.While application of borneol made the levels of noradrenaline and 5-serotonin increased significantly as compared to operational group.Conclusion Borneol have a reversal effect on rat awake activity impairment after long-term continuous operations.And the arousal effects of borneol are associated with the increase of noradrenaline and 5-serotonin levels in the prefrontal cortex.

Neuroblastoma(NB) is the most common extracranial solid malignant tumor in childhood,which has various clinical manifestations.Tumor metastasis or relapse is one of the major causes of death in patients with NB.At present,the treatments of NB are mainly concentrated on the surgery,chemotherapy,radiation therapy,myeloablative therapy and transplantation,tumor targeted therapy,etc.But the treatment of children with high-risk NB is still not optimistic.Studies have shown that multidmg resistance is a major impediment to the successful treatment of NB.Hence,it is of great significance to have a comprehensive understanding of the chemoresistance mechanisms to improve the survival rate of NB patients.This review discusses the chemoresistance mechanisms of NB in several respects.

OATP1B3, a member of SLC superfamily, is specifically expressed on the sinusoidal membrane of hepatocytes and is considered to be important in hepatic drug elimination. The overexpression of OATP1B3 was found recently in tumor tissues such as prostate, colon, and pancreatic tumors. Sequence variations in SLCO1B3 gene, such as SNPs, have been described and a common haplotype consisting of 334T>G and 699G>A SNPs is related to altered transport characteristics of OATP1B3. OATP1B3 is of relevance to drug metabolism through affecting alteration of hepatic concentration of endo- and xenobiotic compounds that interact with nuclear receptors such as PXR and CAR, and thereby directly alter the extent of target gene transcription, including major CYP isoenzymes such as CYP3A4. This review will provide an overview of substrates and inhibitors of OATP1B3 and subsequently to assess the effect of genetic mutation on transport activity. The studies linking OATP1B3 with cancer clinical outcomes are also discussed in this review.

Because the biology characteristic of HIV is extremely different from that of other microorganisms, HIV vaccine research has being faced with unprecedented difficulties and challenges. In the last 20 years, HIV vaccine research has been carried out mainly with two strategies, i.e., neutralizing antibody based and cellular immunization based; however, substantive breakthroughs haven't been achieved until now. Inducing effective neutralizing antibody is always an important strategy in traditional vaccine research, but this strategy is much less efficient in HIV vaccine research because of high variation and much subtypes of HIV. In recent years, the discovery of broadly neutralizing monoclonal antibodies and elucidation of their corresponding antigen epitopes have brought new hopes for the development of neutralizing antibody based HIV vaccine. Reviewing these advancements will be helpful for reconsidering HIV vaccine development with a better strategy.

Retinopathy of Prematurity is a retinal vascular proliferative disease.With the improvement of the medical care in China, retinopathy of prematurity (ROP) has become one of the main causes of child hood blindness in recent years.Several factors such as short gestational age, low birth weight and oxygen supplementation are the three major risk factors for the disease, however, the pathogenesis is still not clear.This review here aims to expand the etiology and pathogenesis of ROP and provide a theoretical basis for the prevention and control of the disease.

Many clinical researches and animal experiments proved that kineditherapy could undoubtedly improve the blood lipid level of dyslipidemia. The mechanism is that kineditherapy can regulate lipid metabolism, lipoprotein and lipoproteinic lipase. On the other hands kinesitherapy also indirectly modulates insulin, adhesion factors and cytokines to influence the blood lipid level. It is important for patients to choose suitable exercises and insist them for a long time. The effect of different activity intensity on lipid level has no distinct difference.

Objective:To explore the regularity of acupoint selection of acupuncture for hypertonia after stroke.Methods:The Chinese literatures about acupuncture and moxibustion for post-stroke myotonia from January 1990 to October 2019 in China Academic Journal Database (Wanfang Data), China National Knowledge Resources Database (CNKI), China biomedical literature service system (SinoMed) and Chinese science and technology journal database (Chongqing VIP) were searched. The data of acupoint, meridian and specific acupoints were retrieved and analyzed in Excel 2016. The SPSS statistics 22 and SPSS model 18.0 was used for descriptive analysis and association rule analysis.Results:A total of 32 literatures were included, involving 33 acupuncture prescriptions and 77 acupoints. The total frequency of acupoint use is 398 times. Among them, Hegu with 23 times mentioned was the most frequently used single acupoint, followed by Waiguan with 22 times. Most of the selected acupoints were large intestine meridian of hand Yangming (87 times) and gallbladder meridian of foot Shaoyang (68 times). The total frequency of application of specific acupoints was 386 times. Intersection (123 times) was the most frequently used specific acupoints. Hegu and Waiguan are the core acupoints with the strongest correlation. Conclusions:Hegu is the preferred acupoint for hypertonia after stroke. Large Intestine Meridian acupoints along upper limb are preferred for hypertonia treatment, and Gall Bladder Meridian along lower limb followed. Local acupoints’ selection and distal acupoints’ selection are emphasized.
