Objective To analyse the changes of metabolic parameters and condition of metabolic syndrome(MS)in females with obstructive sleep apnea-hypopnea syndrome(OSAHS),and explore the interaction between OSAHS and MS.Methods Sixty females undergoing polysomnography were included,and were divided into simple snorer group(n=19),mild OSAHS group(n=21)and moderate to severe OSAHS group(n=20).Epworth sleepiness scale(ESS)scores and metabolic parameters were compared among groups.Forty-one patients with OSAHS were subdivided into group with MS(MS group,n=15)and group without MS(non-MS group,n=26).ESS scores,apnea hypopnea index(AHI),oxygen desaturation index(ODI)and lowest pulse oxygen saturation(LSpO_2)were compared between MS group and non-MS group.Results There was no significant difference in age,body mass index(BMI),total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL),high density cholesterol(HDL),apolipoprotein A-I(apoA-I)and apolipoprotein B(apoB) among simple snorer group,mild OSAHS group and moderate to severe OSAHS group(P>0.05).Correlation analysis revealed ESS was positively related to AHI(r=0.327,P=0.011).ESS scores and proportions of hypertension,fasting plasma glucose(FPG)and MS were significantly higher in moderate to severe OSAHS group than those in simple snorer group(P<0.05).BMI,FPG,TG,proportion of hypertension,ODI and ESS score in MS group were significantly higher than those in non-MS group(P<0.05),while there was no significant difference in AHI and LspO_2 between these two groups(P>0.05). Conclusion ESS score may reflect the severity of OSAHS in females.Females with OSAHS matched for age and BMI have no difference in blood fat.With the increase of severity of OSAHS,glycometabolism can be impaired,the prevalences of hypertension and MS increase.MS can exacerbate the severity of OSAHS,indicating that MS and OSAHS interact with each other.

Objective To explore the clinical signiifcance of combined detection of thyroid stimulating hormone (TSH) and free thyroxin (FT4) in dried blood spots in screening for congenital hypothyroidism (CH) in neonates. Methods The TSH and FT4 levels in dried blood spot were measured by time-resolved lfuorescence immunity in live born neonates from June to December 2013. If the screening was positive, the blood was drawn and the serum TSH and FT4 were measured and compared with the results from dried blood spots. Results In a total of 31 199 neonates screened, 12 cases were diagnosed with CH and the prevalence rate of CH was 1/2 600;4 cases were hyperthyropinemia and no pituitary CH was detected. There was no signiifcant difference between TSH or FT4 levels in dried blood spot and those in serum in neonates diagnosed with CH (P>0.05). Conclusions Combined detection of TSH and FT4 in dried blood spot can be used for neonatal screening of CH. It can be applied for early distinguishing CH from hyperthyropinemia, and also helpful for early diagnosis and treatment of central CH.

International Eye Science 2019;19(4):663-666
AIM: To retrospectively analyze the clinical change of retinal vein occlusion inpatients of the Second People's Hospital of Foshan in the nearby five years.
METHODS: The data of inpatients in the Second People's Hospital of Foshan were collected by the term “retinal vein occlusion”from 2013-01-01 to 2017-12-31. Retrospective analysis of the details for the disease.
RESULTS: Totally 351 patients with retinal vein occlusion were admitted and treated for 473 times in five years. Elder with systemic disease(hypertension, diabetes and renal inadequacy)was more common. The hospital days were significantly statistical difference among five years with the shortest days in 2017. The prevalence of RVO was growing year by year, especially for BRVO, with statistical difference between 2017 and the other four years(P<0.005). Treatments for RVO were mainly including retinal laser, intravitreal injection or both combined. There was significantly statistical difference about the rate of intravitreal injection among five years(P<0.05)with the lowest one in 2013.“1+PRN” therapeutic regimen was more tolerable for patients than “3+PRN”.
CONCLUSION: BRVO is growing more sharply than CRVO in the nearby five years. Retinal laser combined with“1+PRN”intravitreal injection is the main therapeutic regimen for RVO in our hospital.

OBJECTIVETo investigate the morphological changes after chemically extracted acellular nerve allografts transplant.
METHODSSeventy-two rabbits were divided into four groups. Acellular allografts of facial nerve were used in experimental group, and facial nerve autografts, acellular peroneal nerve allografts and peroneal nerve autografts respectively used in three control groups. The morphological changes after transplant were evaluated by modified trichrome staining, immunohistological staining and transmission electron microscope.
RESULTSThe two facial nerve grafts showed numerous regenerated nerve fibers, vessels and as well as a spindle schwann cells arranged longitudinally. No significant difference was observed in the fiber number and myelin thickness between the two groups,while the two peroneal nerve groups showed poor regeneration 6 months after operation.
CONCLUSIONSThe facial nerve allografts showed more neurite regeneration six months after transplant, and the regenerated axons passed through the distal stoma and there were well revascularized and proliferated schwann cells in the grafts.

OBJECTIVETo explore the association between polymorphism in the ACE I/D gene and blood pressure-lowering response to hydrochlorothiazide (HCTZ) in 829 patients.
METHODSHCTZ 12.5 mg was taken once a day for six weeks. The blood pressure reduction and ratio reaching target blood pressure were compared in different ACE genotype groups.
RESULTSThe reduction in SBP of patients carrying DD was greater than that in other groups carrying II or ID (12.2 mmHg versus 5.4 mmHg, 12.2 mmHg versus 4.4 mmHg, respectively, P<0.05). The reduction in MAP of patients carrying DD was also greater than that in other groups carrying II or ID (6.9 mmHg versus 3.9 mmHg, 6.9 mmHg versus 3.6 mmHg, respectively, P<0.05). The ratio reaching target blood pressure in DD groups was significantly higher than that in II or ID groups (P<0.05). The pre-treatment SBP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of SBP. The pre-treatment DBP, aldosterone levels, DD genotype entered the multi-linear regression model significantly and might affect the reduction of DBP. The pre-treatment MAP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of MAP.
CONCLUSIONACE genotyping is associated with blood pressure-lowering response to HCTZ. Specific genotypes might be associated with the response to specific antihypertensive treatment.

BACKGROUNDEmbryo quality and receptivity of the endometrium are two factors that determine the results of in vitro fertilization/intra-cytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET). There is no consensus of the optimal transfer strategy for normal responders or high responders. The current study aimed to find the optimal transfer strategy for different subgroups of patients.
METHODSFrom April 2010 to December 2010, patients who meet the following criteria were included in this study; primary infertility, female age ≤ 35 years, FSH level on female cycle day 2 - 3 ≤ 12 mIU/ml, at least six good quality embryos available on day three. The clinical outcomes using different transfer strategies between normal responders and high responders were reviewed and compared.
RESULTSFor the normal responders, the clinical pregnancy rate of day three double-embryo transfer (DET) was comparable to that of day five elective single blastocyst transfer (eSBT), 64.04% vs. 60.33% (P > 0.05). For the high responders, the clinical pregnancy rate of day five eSBT was significantly lower than that of day three DET, 43.35% vs. 57.21% (P < 0.05). For the high responders, the rates of clinical pregnancy and implantation in frozen-thawed embryo transfer (FET) cycles were notably higher than in eSBT cycles (64.56% vs. 43.35% and 62.11% vs. 43.35% respectively) (P < 0.05).
CONCLUSIONSFor normal responders, eSBT might be an applicable strategy to reduce multiple pregnancy rates while maintaining acceptable overall pregnancy rates. And in order to reduce multiple pregnancies and increase the chance of pregnancy of high responders, FET may be a preferable strategy.

OBJECTIVETo investigate the protein expression of cyclooxygenase 2 (COX-2) and nuclear factor kappa B (NF-kappaB) in gastric mucosa-associated lymphoid tissue (MALT) lymphoma and its clinical significance.
METHODSProtein expression of COX-2 and NF-kappaB in gastric MALT lymphoma were examined by immunohistochemistry of Envision two-step method. The correlations of COX-2 and NF-kappaB expression with Helicobacter pylori (Hp) infection, clinical stage, depth of tumor invasion, tumor size, recurrent rate and treatment were analyzed by univariate, multivariate and Pearson analysis.
RESULTSThe positive expression of COX-2 and NF-kappaB in gastric MALT lymphoma were 48.9%(23/47) and 36.2% (17/47) respectively, and a positive correlation was found between these two factors(r=0.326,P<0.05). Moreover, COX-2 expression was positively correlated with Hp infection,clinical stage, depth of invasion and tumor size (P<0.05). Univariate analysis showed that the overall survival of gastric MALT lymphoma patients with positive COX-2 protein (59.9 months) was shorter than that of patients with negative COX-2 protein (77.8 months), but the difference was not significant (P>0.05). The survival was significantly shorter in gastric MALT lymphoma patients with positive NF-kappaB protein (26 months) than that of patients with negative NF-kappaB protein (123.2 months)(P<0.05). Multivariate Cox regression analysis revealed that clinicopathological stage was independent prognostic factor, and associated with short survival.
CONCLUSIONUp-regulated expression of COX-2 and activation of NF-kappaB are associated with Hp infection in gastric MALT lymphoma, and their protein expression is correlated with the development of tumor and prognosis.
