Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Comparative analysis of variable region ORF14/15 genes of white spot syndrome virus (WSSV) genome in Guangxi Penaeus vannamei (P. vannamei) could provide useful information for the evaluation of genetic diversity and genetic evolutionary relationship among WSSV isolates from Guangxi, China and other places. Based on geographical and temporal considerations, 40 WSSV-positive P. vannamei samples were collected during the period between May 2010 and July 2013 from Beihai, Qinzhou, and Fangchenggang, which were the main P. vannamei production areas in Guangxi, and the variable region ORF14/15 genes of the WSSV genome from all infected samples were amplified by PCR and then subjected to cloning and sequence analysis. Pairwise and multiple alignment analysis was then conducted to evaluate the degree of genetic divergence between different strains. The variable region ORF14/15 genes from 25 of 40 WSSV positive samples were successfully cloned and sequenced; among the ORF14/15 genes of 25 WSSV-positive strains, 22 was 619 bp in length and 3 was 620 bp. All the 25 Guangxi strains carried a 5949-bp deletion in the ORF14/15 region relative to TH-96-II, which has the longest nucleotide sequence in this region; the deletion of Guangxi strains occurred in the middle region of ORF14/15 gene, with only 190 bp and 429 bp/ 430 bp at 5' and 3' ends, respectively, which were coincident with WSSV-IN-05-I in deletion length and position. Sixteen of 25 Guangxi strains had completely identical nucleotide sequences in the variable re gion, and the homology between other strains also exceeded 97.9%. There were single nucleotide substi tution, deletion, and insertion in the ORF14/15 region of Guangxi strains compared with other strains in GenBank. In the phylogenetic tree based on WSSV variable region ORF14/15, the Guangxi strains were closely related and formed a separate branch with Indian strain IN-05-I, but far from other strains in GenBank. The ORF14/15 gene of WSSV isolates in cultured P. vannamei in Guangxi has a large deletion in the middle of the variable region, and the Guangxi WSSV strains show no significant spatio-temporal differences; the Guangxi strains are closer in genetics to Indian strain IN-05-I than other strains in GenBank.

Objective To study the localization of the foramen of Monro on magnetic resonance image (MRI) and its clinical significance.Methods Cranial MRI was observed for 30 normal healthy subjects to study their location,shape and size of the foramen of Monro,as compared to those in 22 patients with hydrocephalus and 14 cases with tumor around their foramen.Results The the foramen of Monro is located between the fornix and the anterior part of thalamus in the normal healthy subjects,with a transverse diameter of 2.8 mm and a vertical diameter of 2.1 mm in average on MRI.Y-shaped structure is formed between their bilateral the foramen of Monro and the 3rd cerebral ventricle.Very obvious changes in shape and size of the foramen of Monro can be observed in patients with hydrocephalus,which sometimes can integrated with the 3rd cerebral ventricle and lateral ventricle,forming a"rabbit-head sign".Meanwhile, imaging of the foramen of Monro varied in patients with tumor around the foramen,depending on its location and size.Conclusions The foramen of Monro has a relative constant position in the brain.Changes in its position,size and shape are important signs suggesting intracranial lesions.An individualized operation plan for a patient should be determined based on those changes.

Non-suicidal self-injury (NSSI) is becoming increasingly common in adolescents and seriously affects their physical and mental health, and it is also a major risk factor for suicide among adolescents. NSSI has now become a public health issue of general concern; however, the identification of cognitive dysfunction in NSSI is still based on neuropsychological cognitive assessment and subjective questionnaire assessment, with a lack of objective evaluation indicators. As a method for studying the cognitive neural mechanism of NSSI, electroencephalography is a reliable tool for finding objective biomarkers of NSSI. This article reviews the recent research on electrophysiology associated with cognitive dysfunction in adolescents with NSSI.

OBJECTIVESTo investigate the values of tandem mass spectrometry (MS/MS) in etiologic diagnosis and understanding therapeutic effect in cerebral developmental retardation, and to help patients in early diagnosis, treatment and favorable prognosis.

METHODSOne hundred and fifty-eight childhood patients with brain heteroplasia were tested from July 2004 to October 2006. The blood was collected on filter paper, punched and extracted into methanol solution with stable isotope labeled internal standards, then derivatized with butanolic-HCl. After preparation, the samples were analysed by tandem mass spectrometry. Eleven MS/MS-positive patients were further analyzed based on gas chromatography/mass spectrometry (GC/MS) analysis of urine, clinical course, and treatment outcome.

RESULTSEleven of 158 patients (7.0%) with inborn metabolic error were confirmed, including five with methylmalonic acidemia, two with propionic acidemia, one with ornithine transcarbamylase deficiency, one with maple syrup urine disease, one with phenylketonuria, and one with biotinidase deficiency. Among them, five were male, six were female, aged from 4 days to 21 months. The clinical manifestations were diverse, including mental developmental retardation or degradation (11 cases), convulsion (5 cases), coma (4 cases), vomiting (4 cases), malnutrition (4 cases), lethargy (3 cases), repeated infection (3 cases), hypotonia (2 cases), etc. Laboratory findings showed metabolic acidosis, hyperammonemia, hyperlactacidemia, anemia, etc. MRI findings of the brain showed cerebral atrophy, a pattern of bilateral T(2)W high signal intensity or/and T(1)W low signal intensity in cerebral white matter and multiple encephalomalacia or vesicular change, ect. In methylmalonic acidemia patients, the early onset with severe acidosis and coma have had a poor prognosis. Improvement was observed in 8 cases after treatment with vitamin B(12), L-carnitine, special milk, low-protein diet or biotin, etc. However 3 MMA patients died.

CONCLUSIONMS/MS was helpful for some patients in etiologic diagnosis and understanding therapeutic effect of cerebral developmental retardation. Early diagnosis and appropriate treatment are essential to improve the prognosis and prevent brain damage.

We report a case of in vitro fertilization and embryo transfer (IVF?ET) with oocyte donation in a woman with premature ovarian insufficiency (POI) complicated by systemic lupus erythematosus (SLE) during pregnancy. The patient had a diagnosis of POI 4 years earlier and 11 weeks after successful pregnancy by IVF?ET with oocyte donation in 2003, she presented with facial edema, and further examinations confirmed the diagnosis of lupus nephritis. She received treatment with prednisone to control the activity of SLE and aspirin and low?molecular?weight heparin to improve placental blood flow with close monitoring of gravida and fetus throughout pregnancy. The condition of the patient remained unstable during pregnancy, and liver damage and placental circulation disorder occurred in late gestational weeks with suspected intrauterine growth retardation (IUGR) of the fetus. For maternal and fetal safety, the patient received elective caesarean section and delivered a premature boy at 31 weeks of gestation. She subsequently received further medications for SLE and showed good recovery of the immunological parameters and absence of SLE symptoms during the follow?up for 14 years, indicating a clinical cure of SLE. Her son shows normal growth and development. Based on the experience with this case and literature review, we believe that immunological factor is an important cause of POI and thus recommend full immunological examinations in cases of idiopathic POI.

OBJECTIVETo investigate the clinical outcomes in vitro fertilization or intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) in women aged over 40 years.

METHODSWe retrospectively analyzed 1050 non-donor IVF/ICSI-ET cycles performed from January, 2007 to December, 2015 in women at the age 40 years or above, including 393 women at 40 years of age, 266 at 41 years, 158 at 42 years, 107 at 43 years, 64 at 44 years, and 65 at 45-51 years. The clinical characteristics and outcomes of the women in different age groups were compared and analyzed. The pregnancy outcome of different ovarian stimulation protocols and different numbers of embryo transferred were also compared.

RESULTSOocyte retrieval was achieved in 1032 treatment cycles. Of the 750 embryo transfer cycles, the clinical pregnancy rate was 17.7% (113/750), and the live birth rate was 8.5% (64/750). The clinical pregnancy rate in the 5 age groups was 23.4%, 21.0%, 13.1%, 9.2%, 5.6% and 0%, and the implantation rate was 11.2%, 10.2%, 6.3%, 5.1%, 2.3% and 0%, respectively; the early spontaneous abortion rate was 31.0%, 35.9%, 42.9%, 42.9% and 100%, and the live birth rate was 11.9%, 11.8%, 2.8% and 3.9%. The clinical pregnancy rates of long protocol, short prorocol, GnRHa antagonist protocol, and ovulation induction protocol were 23.6%, 10.2%, 13.3%, and 2.3%, respectively. In the 750 transfer cycles, the clinical pregnancy rate was 3.8% with single embryo transfer, 12.6% with double embryos transfer, and 23.0% with 3 embryos transfer.

CONCLUSIONIn women aged 40 years or above, the clinical pregnancy rate decreased significantly with age, and the live birth rate was extremely low in women aged beyond 44 years. Assisted reproductive technique is recommended for women aged 40 years and above even when no identifiable causes of sterility are present. For women aged above 44 years of age, oocyte donation may be a better option.

OBJECTIVETo analyze the incidence, management, and outcomes of monozygotic twin (MZT) pregnancy conceived by assisted reproductive techniques (ART).

METHODSA retrospective analysis was performed of clinical pregnancies after in vitro fertilization and embryo transfer (IVF-ET) and introcytoplasmic sperm injection and embryo transfer (ICSI-ET) from January, 2010 to June 2015 at our center. We investigated the incidence, managements and outcomes of 94 MZT pregnancies. Comparison of the pregnancy outcomes was made between the expectantly managed MZT pregnancies, dizygotic twin (DZT) pregnancies, monozygotic (MZ)-triplet pregnancies with selective embryo reduction (SER) to 2 fetuses and 1 fetus, and non-MZ triplet pregnancies with SER to 2 fetuses.

RESULTSNinety-four MZT pregnancies occurred in the total of 6257 clinical pregnancy cycles with an incidence of 1.5%. No significant difference was found in the incidence of MZT pregnancies between IVF and ICSI cycles or between fresh and thawed cycles (P>0.05). Of the 94 MZT pregnancies, 45 were MZT pregnancy cycles, 43 were MZ-triplet pregnancy cycles, 3 were MZ-quadruplet pregnancy cycles and 3 were ectopic pregnancies. The expectantly managed MZT was associated with a significantly greater rate of miscarriage and malformation and a lower rate of live birth and term birth (P<0.05) in comparison with DZT pregnancy cycles that did not undergo SER. Similar outcomes were found between MZ-triplet pregnancies with SER to 2 fetuses and MZ-triplet pregnancies with SER to 1 fetus (P>0.05), and between MZ-triplets with SER to 2 fetuses and non-MZ triplet pregnancies with SER to 2 fetuses (P>0.05).

CONCLUSIONART is associated with a much higher incidence of MZT pregnancies than spontaneous conception. MZT pregnancies are at high risk of adverse outcomes, and reduction of MZT in multiple pregnancies may help to improve the outcomes.
