To investigate the clinical course and management of congenital vaginal atresia.This retrospective analysis included patients with congenital vaginal atresia treated from March 2004 to August 2014 at the Obstetrics and Gynecology Hospital of Fudan University.Thirty-nine patients were included in this study.Their average age was 16.87±2.2 years when they came to our hospital.Totally,51％ of the patients had isolated congenital vaginal atresia with a normal cervix,whereas the others had either cervical atresia or imperforate hymen.The primary presenting signs and symptoms included primary amenorrhea (71.8％),periodic abdominalgia (41.0％),abdominal pain (36.0％),dyspareunia (10.3％),menstrual disorders (5.1％),and pelvic mass (5.1％).Ultrasound and magnetic resonance imaging (MRI) were effective inspection methods for the screening of urogenital tract-associated anomalies.Vaginoplasty mainly included simple vagina reconstruction with insertion of a mold (n=22) and split-thickness skin grafting (n=4).In 64％ of surgical patients,normal menstrual bleeding was achieved.Four of the patients subsequently became pregnant and delivered at term.Primary amenorrhea,periodic abdominalgia and abdominal pain are the main reasons for the post pubertal patients to visit doctors.Surgical methods can successfully provide these patients an opportunity for subsequent conservative management,can result in normal menstrual bleeding,resolve cyclic pelvic pain,and provide some potential for fertility.

Objective:To study the effect of total saponins on cerebral blood flow and vascular resistance in anesthetized dogs.Methods:Thirty hybrid dogs in either sex,with a body weight of(11?1.5)kg,were evenly randomized into 5 groups: negative control group(saline 5 ml/kg,ig),positive control(nimodipine 300?g/kg,iv),and 3 groups treated with total saponins (low-dose group[10 mg/kg,ig],middle-dose group[30 mg/kg,ig],and high-dose group[60 mg/kg,ig]).The dogs were anes- thetized with intravenous pentobarbital sodium(30 mg/kg).The right common carotid artery was exposed to measure the cere- bral blood flow,cerebral vascular resistance,blood pressure and heart rate using the MFV-3200 electromagnetic flow meter and MPA-3000 bioelectricity signal-amplifier.Results:Compared with negative control,cerebral blood flow was significantly in- creased in animals treated with asparagus root saponins(30 and 60 mg/kg,ig)during 5 and 120 min after drug administration (P

Both the morbidity and mortality of ovarian cancer, among malignant tumors ot temale genital organs, are quite high. The traditional therapeutic methods on ovarian cancer are surgical operation, chemotherapy, radiotherapy and combination of these methods mentioned above. In recent years, some components of traditional Chinese medicine, such as genistein, semen Coicis, phytosterols, curcumin, quercetin, ginsenoside, etc. have been found to exert anticancer actions of inhibiting proliferation and inducing apoptosis of cancer cells, increasing the sensitivity of patients to chemotherapeutic agents in viva and/or in vitro, the mechanisms involve such aspects as inhibiting activity of key enzymes in cell metabolism, affecting gene expression, antioxidation, and inhibiting tumor angiogenesis, etc. As an adjuvant therapeutic means, the bioactive components of traditional Chinese medicine have broad future of clinical application.

OBJECTIVEThis review aimed to update the progress of microRNA (miRNA) in early detection of ovarian cancer. We discussed the current clinical diagnosis methods and biomarkers of ovarian cancer, especially the methods of miRNA in early detection of ovarian cancer.

DATA SOURCESWe collected all relevant studies about miRNA and ovarian cancer in PubMed and CNKI from 1995 to 2015.

STUDY SELECTIONWe included all relevant studies concerning miRNA in early detection of ovarian cancer, and excluded the duplicated articles.

RESULTSmiRNAs play a key role in various biological processes of ovarian cancer, such as development, proliferation, differentiation, apoptosis and metastasis, and these phenomena appear in the early-stage. Therefore, miRNA can be used as a new biomarker for early diagnosis of ovarian cancer, intervention on miRNA expression of known target genes, and potential target genes can achieve the effect of early prevention. With the development of nanoscience and technology, analysis methods of miRNA are also quickly developed, which may provide better characterization of early detection of ovarian cancer.

CONCLUSIONSIn the near future, miRNA therapy could be a powerful tool for ovarian cancer prevention and treatment, and combining with the new analysis technology and new nanomaterials, point-of-care tests for miRNA with high throughput, high sensitivity, and strong specificity are developed to achieve the application of diagnostic kits in screening of early ovarian cancer.

OBJECTIVETo study the effects and its possible mechanism of Naoweikang (NWK), a composite of ginseng and ginkgo extracts, on hippocampal neurotransmitters in APP transgenic mice.

METHODSP-DAPPV717I transgenic mice were taken as the model of Alzheimer's disease (AD) and be treated with different doses of NWK (31 mg/kg and 62 mg/kg) respectively by gastrogavage once per day for 12 weeks. Contents of hippocampal acetylcholine (ACh), monoamine neurotransmitters and their metabolites were determined with high performance liquid chromatography.

RESULTSCompared with nontransgenic mice, the levels of ACh and 5-HIAA in hippocampus of transgenic mice lowered significantly (P < 0.01), while 5-HT increased significantly (P < 0.05), and the levels of norepinephrine and dopamine increased by 14.6% and 17.7%, respectively. After 12-week administration, the ACh level increased significantly in the two NWK treated groups (P<0.05), and the 5-HT level in the high dose NWK treated group decreased (P<0.05), as compared with those in the untreated transgenic mice.

CONCLUSIONNWK shows a significant regulatory effect on the activities of hippocampal acetylcholine and monoamine system, especially the cholinergic and 5-HT systems, in APP transgenic mice, which might be one of its mechanisms in improving learning and memory of AD model, and therefore, NWK might exert certain curative effect on AD.

To observe the protective effect and mechanism of Sailuotong capsule in focal cerebral ischemia/reperfusion. The 90 min middle cerebral artery occlusion (MCAO) reperfusion model was established. The expressions of dynamin-related protein 1 ( Drp1) and optic atrophy 1 (Opa1) were tested by Western blot. The transmission electron microscope was used to observe the changes in the mitochondrial ultra-structure. The pathological morphological changes were observed through the HE staining. The immunohistochemical method was used to test Drp1 and Opa1 expressions. Sailuotong capsule (33, 16.5 mg x kg(-1), ig) can inhibit the abnormal mitochondrial fission and fusion in the cortical area on the ischemia side and the mitochondrial fission gene expression and promote the mitochondrial fusion gene Opa1 expression, so as to alleviate the energy metabolism disorder caused by ischemia/reperfusion. Sailuotong capsule can inhibit the abnormal mitochondrial dynamics in peri-ischemic regions and maintain the normal morphology of mitochondria, which may be the mechanism of Sailuotong capsule in promoting the self-recovery function in the ischemic brain region.

This study was aimed to establish a simple, sensitive detection method for multiple NPM1 mutations, so as to reduce the omission ratio of NMP1 mutant detection. Recombinant plasmids containing wide-type NPM1 and the most common mutations (A, B, C, D) were constructed as the detection objects. The ARMS-PCR for detecting multiple NPM1 mutations was established through designing a pair of specific primers whose 3' end base matched with four mutants (A,B,C,D), but did not matched with wild type NPM1 according to the different base sequence of NPM1 mutants. The feasibility of the ARMS-PCR method was evaluated by assessing the detection range and the sensitivity and comparing with direct sequencing. The results showed that the recombinant plasmids were constructed successfully by restriction analysis and DNA sequencing. The four mutants but not wild type NPM1 were detected by using ARMS-PCR, the detection range of the method was 10(3) copies/ml -10(9) copies/ml and the sensitivity was 0.01%, while the direct sequencing method could not detect the mutations if mutation was less than 10%. It is concluded that the high sensitive ARMS-PCR is established for detecting the four mutations of NPM1 and more than 95% mutants can be detected by this method, providing a new detection method for clinical NPM1 gene mutant.

OBJECTIVETo observe the intervention and mechanism of Weinaokang capsule (WNK) on cognitive impairment rats induced by chronic cerebral hypoperfusion.

METHODThe bilateral common carotid arteries of rats were ligated. Rats were intragastrically administrated with WNK 4 weeks after the ligation. After 8 weeks of administration, persistent time of rats on finding the platform in MORRIS water maze was measured, meanwhile, content of acetylcholine (ACh) in brain tissue was measured by HPLC-ECD, activity of acetylcholine esterase (AChE) and superoxide dismutase (SOD), content of malonaldehyde (MDA) was measured by colorimetric method.

RESULTAfter 4-8 weeks of administration, the time of finding the platform in WNK group was significantly shorter than in the model group, activity of AChE in brain tissue was significantly reduced (P < 0. 05), content of ACh was significantly increased (P < 0.05-0.01), activity of SOD was significantly reinforced (P < 0.05).

CONCLUSIONWNK capsule can improve the cognitive impairment induced by chronic cerebral hypoperfusion, and its mechanism may be associated with reinforcing the capability of scavenging free radical and protecting the cholinergic system.
