0.05). Conclusion:There is bigger difference process of tumor apoptosis between different cell types in the same topography site. Survivin may play adjuvant roles and Bcl-2 may play main roles in the inhibition of cell apoptosis in SCLC while the case is just reversed in NSCLC,it suggests that there were different apoptosis inducing factor and different apoptosis pathway due to different cell type in NSCLC and SCLC.

Objective To observe the characteristics of images of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) in patients with acute retinal necrosis syndrome (ARNS), and investigate the applied value of FFA and ICGA in clinical diagnosis. Method The data of the ocular fundus, FFA and ICGA of 20 patients (28 eyes) with ARNS were retrospectively analyzed. Results The images of FFA indicated hyperfluorescence of optic disc in 24 eyes (85.71%) at the late phase; widespread retinal vascular occlusion at the peripheral focus in 23 eyes (82.14%) with some occlusive vascular shadow and the fluorescein in some white-line-like blood vessels; fluorescent leakage at the junction of normal and abnormal retina in 22 eyes (78.57%); retinal detachment in 20 eyes (71 42%), including 9 with retinal hole (45% of the patients retinal detachment); and macular cystoid edema in 8 eyes (28 57%). The images of ICGA showed hyperfluorescence of optic disc in 8 eyes (28 57%) including 5 with dotted staining at the optic disc at the late phase; unclear choroidal vasculature in the peripheral focus in 20 eyes (71.42%); and choriodal scattered hypofluorescent patch at the focus area in 19 eyes (67.85%). At the late phase of ICGA, some intravascular emboli and segments of retinal vascular occlusion were clearly demonstrated. Conclusion The main manifestations of patients with ARNS in the images of FFA were hyperfluorescence of optic disc and retinal vascular occlusion; and unclear choroidal vessels and scattered hypofluorescent patch at the focus area.Combination of FFA and ICGA is helpful to understand the extent of the lesions and the relations between choroids and retina, which has great significance in diagnosing ARNS.

ObjectiveTo explore the relationship between flash visual evoked potentials (fVEP) and intracranial pressure (ICP), and the effect of fVEP on monitoring ICP treatment.MethodsICPs of 37 patients with large area cerebral infarction and intracranial hypertension were measured before and at 10 min, 20 min, 30 min, 40 min, 50 min and 60 min after mannitol treatment.ResultsThe mannitol effect to cure the large area cerebral was not well.ConclusionfVEP can monitor ICP exactly and harmless, and has importance value to instruct therapy of ICP in clinic.

Objective To explore the factors affecting results of alanine aminotransferase(ALT)preliminary screening by using dry chemical method in blood donors,so as to establish standards of ALT preliminary screening and reduce waste of blood. Methods A total of 21 065 blood specimen of blood donors in Blood Center of Maoming City were collected from January to June 2013.The influences of specimen hemolysis,lipidemia,different sample amount and waiting time after adding sample on the detec-tion results of ALT by using dry chemical method were comparatively analysed,and standardized procedures and established appro-priate limits of ALT preliminary screening according to the results.Results The specimen hemolysis affected test results of ALT, which was not obvious when the hemolysis rate was less than or equal to 0.5%.There was no obvious interference of lipidemia on ALT test.When the sample amount was (32±3)μL or the waiting time after adding sample was 10 to 40 seconds,the detection re-sults of ALT were acceptable.The standard limit of ALT was less than or equal to 40 U/L of female and less than or equal to 45 U/L of male.Conclusion Hemolysis,sample amount and waiting time after adding sample can influence the results of ALT detec-ted by using dry chemical method,while lipidemia had no interference on ALT test.Standardizing operation and reasonably setting normal limits standard may ensure the accuracy and stability of determination,save blood resources,further ensure blood safety, which should be worthy of wide application.

Objective:To investigate the clinical significance of Her2 pathological expression in the breast and gastric cancer patients for providing a reference for cancer prevention. Methods: Selected surgical resection specimens of 60 diagnosed in advanced gastric cancer and 60 diagnosed with advanced breast cancer from March 2009 to May 2014 in our hospital,all specimens were given the Her2 pathological expression of immunohistochemical analysis and investigation the clinical and pathological data. Results: The Her2 positive expression rates in the breast cancer and gastric cancer specimens were 40. 0% and 36. 7%,respectively that compared to no significant difference (P>0. 05). The Her2 expression was not related to the cancer patient’s age,histological type,and there were sig-nificantly correlated to the TNM stage and lymph node metastasis ( P<0. 05 ) . Spearman correlation analysis showed that Her2 expression in the breast cancer and gastric cancer were significant positive correlation to the Survivin, Bcl-2 expression ( P<0. 05 ) . Conclusion:Breast cancer and gastric cancer patients have shown high pathological expression of Her2,and are related to the TNM stage and lymph node metastasis, it may be through inhibited the apoptosis regulating proteins involved in the pathogenesis and metastasis of tumors.

Objective To compare the effect of botulinum toxin A(BTX-A)applied according to experi- ence with its effect when the application is guided by electrical stimulation on spasticity in the ankle plantarflexors of children with cerebral palsy(CP).Methods Forty-five children with CP were randomly assigned into 2 groups to receive injections of BTX-A guided by electrical stimulation,or injections of BTX-A guided by experience.All chil- dren received a local injection in the ankle plantar flexors.Physiotherapy and ankle-foot orthoses were applied by a physical therapist 3 days after the BTX-A injections.After the first 10 days,the therapy was administered by the patient's family.Clinical assessments included the patient's passive range of movement(PROM),scoring on the Ash- worth scale(MAS),the composite spasticity scale(CSS),and the D and E dimensions of the gross motor function measure(GMFM),and walking velocity(WV).Assessments were performed before treatment and at 3 days,2 weeks,1,2,and 3 months following the injection with BTX-A.Results All children showed significant decrease in spasticity(PROM,MAS and CSS)after 3 days.The improvement was maintained at 3 months.When compared with the results before the injection,the improvements in standing and walking(GMFM)and in walking velocity were statistically significant after 2 weeks of treatment for both groups,and were maintained at 3 months.The differences in PROM and CSS scores at 3 days,2 weeks,1,2,and 3 months following the injection were statistically significant between the 2 groups.Significant differences were also found between the 2 groups in MAS scores at 3 days,2 and 3 months after treatment,and in GMFM and WV at 2 and 3 months after treatment.Conclusions A BTX-A injec- tion,whether guided by electrical stimulation or experience,in combination with physiotherapy,can reduce spasticity in the ankle plantarflexors of ambulant children with CP and improve their functional performance.BTX-A injection guided by electrical stimulation was more effective than an injection guided by experience.

Brain injury is one of the most serious diseases in neonatal period,which can cause cerebral palsy,motor development delay,cognitive dysfunction and learning difficulties and other sequelae,and severely affects the health development and quality of life of the newborn.Neonatal brain injury (NBI) is a wide range of diseases caused by a variety of causes,its clinical manifestations lack specificity,clinically,it is difficult to judge the severity,duration and the time of prenatal injury,and it has been paid much attention to by scientific researchers and clinicians.At present,imaging method is a major means of NBI diagnosis,but imaging examination is usually a lag and limitations.Levels of humoral biomarkers change early after brain injury,and early brain injury can be predicted by detecting their changes.In recent years,a variety of sensitive brain damage biomarkers have been detected in various body fluids of newborns,mainly including neuron-specific enolase (NSE),ubiquitin carboxyl hydrolase L1 (UCH L1),S100B protein,tau protein,myelin basic protein (MBP),glial fibrillary acidic protein (GFAP) and activin A and so on.the application and research progress of these commonly used biomarkers in NBI are reviewed in this paper.

OBJECTIVE:To investigate clinical efficacy and safety of goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing levonorgestrel intrauterine system (LIS). METHODS:A total of 140 adenomyosis pa-tients with severe dysmenorrheal were selected from Sanya Family Planning Technology Service Center during Jan. 2014-Jan. 2016, and then divided into control group and observation group according to lottery method,with 70 cases in each group. Both groups re-ceived LIS within first 7 d of menstruation,and observation group was given Goserelin acetate sustained-release implant 10.8 mg subcutaneously via anterior abdominal wall one week before placing. Therapeutic efficacy was evaluated 6 months later. The im-provement of dysmenorrhea was compared between 2 groups. The uterine volume,COX dysmenorrhea score (CMSS),menstrual volume,hemoglobin (Hb) and CA125 content were compared between 2 groups before and after treatment. The occurrence of ADR was also compared. RESULTS:The rate of dysmenorrheal improvement in observation group was 95.71％,which was signifi-cantly higher than 81.43％of control group,with statistical significance(P<0.05). Before treatment,there was no statistical signif-icance in above indexes between 2 groups (P>0.05). Compare to before treatment,CMSS score,menstrual volume and CA125 content of 2 groups were decreased significantly after treatment,while Hb content was increased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in uterine volume between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR(10.00％ vs. 14.29％)between 2 groups(P>0.05). CONCLUSIONS:Goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing LIS can effectively relieve dysmenorrheal,reduce menstrual volume and improve Hb and CA125 levels,but do not increase the risk of ADR.

Objective To know the situation of the hepatitis C virus(HCV)infection in blood donors of Maoming City,and pro-vide the basic data for recruiting volunteer blood donors and preventing of HCV infection.Methods Blood samples were collected in Maoming blood center,and were detected by using HCV antibodies of different manufacturers and operated by different people.Du-plicate test was used to reexamine the specimens which were reactive in the initial test.Statistical analysis was performed.Results HCV prevalence of blood donors from Maoming was 0.74%.The prevalence of female was slightly higher than the male,but the difference was not statistically significant(P >0.05).The HCV prevalence of civil servant and medical personnel was relatively low-er.HCV prevalence of repeat blood donors was obviously lower than blood donors for the first time(P <0.05).Conclusion HCV prevalence of blood donors in Maoming City was in a relative low level.The risk of HCV infection in people who is younger than 35 years old and at the same time qualified to donate blood is quite low.Establish a stable volunteer blood donor group is beneficial to blood safety.It's necessary to strength the propaganda and prevention of HCV knowledge to population besides civil servant and medical personnel,which would be helpful for the control of HCV infection.

Objective To explore the efficacy of sequential or combined amphotericin B (AmB) and fluconazole (FCZ) therapy on a 5 flucytosine based regimen in non-acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis.Methods A tatal of 117 cases of non-AIDS-related cryptococcal meningitis treated with 5-flurocytosine-based regimens were retrospectively divided into five groups:AmBgroup (n=38),FCZ group (n=25),FCZ and AmB sequential group (n=18),AmB and FCZ sequential group (n=15),AmB and FCZ combination group (n=21).The number in cerebrospinal fluid (CSF) of the five groups were compared.Statistical analyses included t test,oneway analysis of variance,K-independent samples test and chi-square test.Results Intracranial pressure of AmB group,FCZ group,FCZ and AmB sequential group,AmB and FCZ sequential group,AmBandFCZ combination group were (208.6±75.1),(191.5±94.5),(185.0±76.3),(201.9±69.7) and (223.1±89.3) mm H2O (1 mm H2O=0.0098 kPa),respectively,and the differences were not statistically significant (F=0.611,P =0.656).Median cryptococcus counts in CSF of the five groups were 0,10,0,3 and 0/mL,respectively,with no statistical significance (x2 =7.638,P-0.090).CSF protein levels of the five groups were 0.55,0.69,0.67,0.53 and 0.96 g/L,respectively,with no significant differences among groups (F=7.063,P=0.133).The cure rates of the five groups were 55.3％ (21/38),32.0％ (8/25),9/18,6/15 and 47.6％ (10/21),respectively;progression rates or mortality of the five groups were 28.9％ (11/38),44.4％ (11/25),5/18,4/15and 23.8％ (5/21),respectively; and the differences among cure rates (x2 =3.638,P=0.457) and progression rates or mortality (x2-2.785,P =0.604) were not statistically significant.Conclusion FCZ or AmB alone,sequential or combined therapy were all effective in the treatment of cryptococcal meningitis.
