AIM: To explore the effect of Buddleia flavonoids drug-containing plasma and androgen receptor(AR) blocker on the expression of STAT1 phosphoprotein.METHODS: In vitro lacrimal gland epithelial cells were cultivated with H2O2 to establish the dry eye apoptosis state. Blank plasma group, Buddleia officinalis plasma total flavonoids interfere with drug-containing group, and the intervention group of testosterone propionate were set. The expressions of STAT1 phosphoprotein of each group were observed by Western blot and AR blocker flutamide was used to explore the intended androgen effect of Buddleia flavonoids.RESULTS: After the intervention of drug-containing plasma, the expression of STAT1 Phosphoprotein in Buddleja officinalis drug-containing plasma intervention group(0.353±0.494) and testosterone propionate intervention group(0.502±0.036) were enhanced and the differences between the two groups were significant (P<0.01). After using the AR blocker in all groups, the expression of STAT1 phosphoprotein in each group (0.268±0.061,0.283±0.106,0.213±0.071) had no difference.CONCLUSION: Buddleja officinalis drug-containing plasma total flavonoids can promote the expression of STAT1 phosphorylation.

In this study,we aimed to study the pattern visual evoked potentials (P-VEPs) in two eyes with varying visual acuity in one eye and to provide an objective estimation of visual acuity by comparing P-VEPs in one and two eyes.Thirty subjects were chosen,who had one eye with an acuity of 5.0,4.85,4.6,4.0,or scieropia and obstructed vision and the other eye with an acuity of 5.0,respectively.P-VEPs were detected under the large grating stimuli at 3×4 spatial frequency,moderate grating stimuli (12× 16 spatial frequency) and small grating stimuli (48×64 spatial frequency).Under large grating stimuli,there was no significant difference in P100 peak latency between the groups,nor was there a significant difference between the amplitude of two eyes and the amplitude of one normal-vision eye.Under moderate and small grating stimuli,there was a significant difference in P100 peak latency between the group with both eyes having an acuity of 5.0 and the group with visual acuity below 4.0 in one eye.There was a significant difference in P100 amplitude between the group with visual acuity of 5.0 in both eyes and the group with one normal-vision eye.There was no significant difference in the amplitude of two eyes and the amplitude of one normal-vision eye between any other two groups.In forensic identification,characteristics and variability of P-VEPs in one and two eyes can be used to identify malingering or decline in visual acuity.

Human-animal parasitic diseases caused by medical helminths are hazardous to human health. Genetic polymorphism studies on medical helminth populations can not only understand the biological characteristics and genetic structure of their populations, but also help reveal how they adapt to their parasitic environment, thus contributing to deepen our understanding of the epidemiological patterns of parasitic diseases and improve our understanding of accurate prevention and control of parasitic diseases. With the development of molecular biology, molecular markers such as DNA barcodes, simple sequence repeats, and single nucleotide polymorphism markers have been widely used to study the genetic relationships among parasite populations and individuals, and to reveal the genetic variation of parasite populations and the evolution of species origins. In this paper, we systematically review the application of three molecular markers commonly used in the study of genetic polymorphism in medical helminths, with a view to laying the foundation for related research.

OBJECTIVETo analyze the relationship between genotype and phenotype of homozygous hemoglobin Constant Spring (Hb CS) in Guangxi province, and to explore the reasons of missed diagnosis and the methods for screening and diagnosing.
METHODSScreening Hb CS by acetate fibrous membrane electrophoresis with benzidine staining. Gene mutation of homozygous Hb CS by polymerase chain reaction (PCR) and DNA sequencing.
RESULTSOut of the 9 patients, 4 had no clinical symptoms, 2 showed mild anemia and splenomegaly, 3 were jaundice. Hemoglobin levels were normal or mild anemia. MCVs were normal or reduced. Peripheral blood smear of all the patients displayed hypochromia, anisocytosis, poikilocytosis and target cells. The quantities of HbA(2) + Hb CS were 4.3% - 6.72%, while HbA(2) < 2%. Gene analysis confirmed the diagnosis of homozygous Hb CS.
CONCLUSIONThere was quite different in clinical symptoms, hematological parameters and hemoglobin quantifications for patients with homozygous Hb CS. They might have no clinical and hematological signs and looked like the phenotype of Hb H disease. Homozygous Hb CS was very easy to miss diagnosis. Gene analysis can be helpful.

BACKGROUNDThe persistence of sleep disordered breathing (SDB) symptoms after tonsil and/or adenoid (T&A) surgery are common in children with obstructive sleep apnea (OSA). We tested the hypothesis that disturbances of glucose transporters (GLUTs) in intraabdominal adipose tissue caused by chronic intermittent hypoxia (CIH) from the pedo-period could facilitate the appearance of periphery insulin resistance in Sprague-Dawley (SD) rats. We tested the hypothesis that the changes of GLUTs in adipose tissue may be one of the reasons for persistent SDB among clinical OSA children after T&A surgery.
METHODSThirty 21-day-old SD rats were randomly divided into a CIH group, a chronic continuous hypoxia (CCH) group, and a normal oxygen group (control group) and exposed for 40 days. The changes of weight, fasting blood glucose and fasting blood insulin levels were measured. Hyperinsulinemic-euglycemic clamp techniques were used to measure insulin resistance in each animal. Real-time quantitative PCR and Western blotting were used to measure GLUT mRNA and proteins in intraabdominal adipose tissue. Additional intraabdomial white adipose tissue (WAT) was also processed into paraffin sections and directly observed for GLUTs1-4 expression.
RESULTSWhen compared with control group, CIH increased blood fasting insulin levels, (245.07 +/- 53.89) pg/ml vs. (168.63 +/- 38.70) pg/ml, P = 0.038, and decreased the mean glucose infusion rate (GIR), (7.25 +/- 1.29) mg x kg(-1) x min(-1) vs. (13.34 +/- 1.54) mg x kg(-1) x min(-1), P < 0.001. GLUT-4 mRNA and protein expression was significantly reduced after CIH compared with CCH or normal oxygen rats, 0.002 +/- 0.002 vs. 0.039 +/- 0.009, P < 0.001; 0.642 +/- 0.073 vs. 1.000 +/- 0.103, P = 0.035.
CONCLUSIONSCIH in young rats could induce insulin resistance via adverse effects on glycometabolism. These findings emphasize the importance of early detection and treatment of insulin insensitivity in obese childhood OSA.

BACKGROUNDIn clinical studies there is still a lot of controversy about the increased anterior and rotational stability between double-bundle (DB) and single-bundle (SB) anterior cruciate ligament (ACL) reconstruction. The aim of this study was to evaluate the clinical results of four-tunnel DB ACL reconstruction.
METHODSSixty-four consecutive patients with ACL ruptures from May 2005 to May 2006 were randomly assigned into two groups: 32 cases for SB ACL reconstruction and 32 cases for DB ACL reconstruction. Clinical data, including KT 2000, Biodex test, Lysholm score, Tegner score and IKDC score, were prospectively collected until at least 10 months post-operative.
RESULTSThe average values of KT 2000 were (1.47 +/- 1.17) mm and (1.68 +/- 1.14) mm for the SB and DB ACL reconstruction groups at 30 degrees of knee flexion (P > 0.05), and were (1.04 +/- 0.98) mm and (1.13 +/- 0.98) mm at 90 degrees of knee flexion (P > 0.05). There were also no significant differences in Lysholm score, Tegner score, IKDC score and Biodex test scores between the two groups (P > 0.05). The operation time of DB ACL reconstruction was 20 minutes longer than the SB ACL reconstruction (P < 0.05).
CONCLUSIONDouble bundle ACL reconstructions have no obvious clinical advantages over single bundle ACL reconstructions.

Rheumatoid arthritis of the knee is a common disease, but suppurative arthritis caused by Gemella morbillorum in the same joint is rare. We report a case of suppurative arthritis caused by Gemella morbillorum in a patient with rheumatoid arthritis. Because the infection symptoms was not typical, the diagnosis was delayed, and the delayed diagnosis and therapy led to a poor outcome of the patient.

OBJECTIVETo investigate the therapeutic effect of penoplasty with scrotal skin flap for the treatment of buried penis in children.
METHODSThe narrow ring was cut vertically at the ventral side of penis and the prepuce inner plate was circularly cut 0.5 cm from the coronary sulcus. The prepuce was degloved to the base of penis. The abnormal aponeurosis was removed completely. The prepuce was designed to cover the coronary sulcus. The scrotal flaps at both sides were formed and advanced to cover the penile base. Then the prepuce was sutured to reconstruct penile-scrotal angle and scrotum plasty was completed.
RESULTSFrom March 2009 to July 2011, 24 children with buried penis were treated with scrotal flaps. Adhesion at external orifice of urethra was happened in two cases which recovered after urethra expansion. There was one case of necrosis at the distal end of prepuce. All the cases were followed up for 6 months to 2 years with no penile shrinkage. The penile appearance was good without rotation or lateral curvature during erection.
CONCLUSIONSThe buried penis can be best corrected with scrotal flap. It is an ideal method with less complication.

OBJECTIVETo study the effects of environmental enrichment on neuron proliferation, learning and memory ability and motor ability in neonatal rats with hypoxic-ischemic brain damage (HIBD).
METHODSOne hundred and eight 7-day-old Sprague-Dawley rats were randomly divided into three groups: sham operation (CON group), HIBD and intervention group. HIBD model was prepared according to the classic Rice-Vannucci method. Environmental enrichment was administered for the rats in the intervention group after HIBD inducement. Behavioral tests (Water maze test, Suspension test and Slope test) were performed and the number of neural cells in the left hippocampus was examined 7, 14 and 28 days after intervention.
RESULTSThe pyramid cells in the hippocampus CA1 area in the HIBD group were significantly less than in the CON group at 7, 14 and 28 days (P<0.05). The number of pyramid cells in the hippocampus CA1 area in the intervention group was significantly higher than in the HIBD group (P<0.01) at 7, 14 and 28 days. The hidden platform escape latency period (EL) in the Water maze test was significantly more prolonged and the cross-platform number within 2 minutes was significantly less in the HIBD and the intervention groups than in the CON group at all observed time points (P<0.01). The EL was significantly shorter and the cross-platform number within 2 minutes was significantly higher in the intervention group than in the HIBD group at all observed time points (P<0.01). The maintain time and score in the Suspension test were significantly lower and the time in the Slope test was significantly more prolonged in the HIBD and intervention groups than in the CON group at 7, 14 and 28 days (P<0.01). An increased maintain time and score and a decreased time in the Slope test were found in the intervention group compared with the HIBD group at 14 and 28 days (P<0.01).
CONCLUSIONSEnvironmental enrichment can improve motor function, learning and memory ability, and promote the repair and proliferation of neurons in neonatal rats with HIBD.
