To compare posterior choroidal thickness in high myopia amblyopia eyes at different points to high myopia and normal eyes of Chinese children and investigate the relationships between choroidal thickness, axial length and age.METHODS: Fifty Chinese children (65 eyes) with age 4~15 years ( mean 9. 91 ± 3. 41 years) were recruited. By atropine optometry they were divided into high myopia amblyopia group ( 24 eyes ) , high myopia group ( 19 eyes ) , and normal group ( 22 eyes ) . Choroidal scans were obtained for all eyes using enhanced depth imaging spectral-domain optical coherence tomography ( EDl-OCT) . Subfoveal choroidal thickness (SFCT), macular thinkness, choroidal thickness and retinal thickness at 0. 5, 1. 0, 1. 5, 2.0, 2.5, 3.0mm superior (S, 12:00 position), temporal ( T, 9:00 position) , inferior ( l, 6:00 position) , nasal ( N, 3:00 position) were measured. Meanwhile, axial lengths of all eyes were measured by A-Scan. RESULTS: Compared high myopia group and emmetropia group, SFCT and the thickness of choroids on each position were thinnest in high myopic amblyopia group, with statistically significant differences (P<0. 05). There was a significant negative correlation between SFCT and axial length in high myopic amblyopia group (r=-0. 531, R2 =0. 282, F=7. 476, P=0. 013), with no relative in age (r=-0. 292, R2=0. 085, F=2. 044, P=0. 167).CONCLUSlON: The choroidal thickness thinning in high myopic amblyopia shows a negative correlation with axial length.

Objective To investigate the role of Th17 cells and related cytokines in Helicobacter pylori(H.pylori) infection.Methods To establish a mouse model of H.pyloriinfectious gastritis.Meanwhile,a treatment group and control group were set up.The histological changes in the gastric mucosa were observed and scored under light microscopy;The expression of IL-17 and IL-23 mRNAs as well as protein in gastric tissue was detected by RT-PCR and ELISA,respectively;Th17 cells in mice splenocyte were evaluated using the flow cytometry (FCM) method.Results We found significantly higher levels of IL-17 and IL-23 protein and mRNA levels in supernatant of gastric tissue homogenates of infection group as compared to controls and Th17 cells in spleen from mice of H.pylori infection group were all obviously higher than that of control group;IL-17 mRNA,IL-23 mRNA and the ratio of Th17 cells in mice splenocyte of H.pylori infection group mice increased gradually with the time prolonged;The levels of both mRNA and protein levels of IL-17and IL-23 decreased significantly in the treatment group compared with pre-treatment;There was a positive correlation between IL-17 and IL-23 expression levels of mice gastric mucosa and gastric inflammation degree.Conclusion H.pylori infection induced the immune response of Th17 cells;The levels of IL-17 and IL-23 increased in gastric mucosa of mice after H.pyloriinfection;The degree of H.pylori-infected mice gastric inflammation was positive correlation with the levels of IL-17 and IL-23 of gastric mucosa.

Objective To investigate the influence of thymosin beta 4 (Tβ4) with two different dosages on the expression of transforming growth factor beta (TGF-β) and connective tissue growth factor (CTGF) in rats with renal tubular interstitial fibrosis,and to further estimate the changes of renal tubular interstitial lesions.Methods Rat models of renal tubular interstitial fibrosis were established by unilateral ureteral occlusion (UUO).The male SD rats were randomly divided into 4 groups and 15 rats in each group:sham group,model group,treatment group with 1 mg/L Tβ4 and treatment group with 5 mg/L T34.Rats in sham group and model group were poured into the same amount of saline.The renal function and renal pathological changes were observed after the second week.The mRNA and protein expression of TGF-β and CTGF in renal tissues was tested by in-situ hybridization and Western blotting.Results Compared with that in sham group,the expression of TGF-β mRNA and its protein,CTGF mRNA and its protein was significantly higher in model group (all P ＜ 0.01).Compared with rats of model group,Tβ4 treatment rats had lower mRNA and protein expression of TGF-β and CTGF (all P ＜ 0.01),and the expression in treatment group with 5 mg/L Tβ4 was lower than that in treatment group with 1 mg/L Tβ4 (P ＜ 0.05).And the expression of TGF-β mRNA was positively correlated with CTGF mRNA expression (r=0.697,P ＜ 0.01).The 24 h total urinary protein and the area of renal tubular interstitial lesion in model group were significantly more than those in sham group,and also more than those in Tβ4 treatment group (all P ＜ 0.05).Tβ4 treatment attenuated kidney damage,and the effects in treatment group with 5 mg/L Tβ4 were better than those in treatment group with 1 mg/L Tβ4.No difference in serum creatinine and blood urea nitrogen was observed among 4 groups (all P ＞ 0.05).Conclusions Tβ4 treatment can inhibit the renal TGF-β and CTGF expression of rats with tubular interstitial fibrosis in a dose-dependent manner,and play a protective role in kidney.

Objective To investigate whether the percutaneous ethanol injection (PEI)under sedation and analgesia can in-crease the energy deposition and curative efficiency of the high intensity focused ultrsound(HIFU)in treating unresectable middle and advanced stages of primary liver cancer.Methods Thirty-six cases of clinically diagnosed unresectable middle and advanced sta-ges of primary liver cancer were randomly divided into the PEI+ HIFU group(combination group,n = 23)and the simple HIFU group (HIFU group,n=13);10mL of the mixture of 99.7% ethanol and iodized oil (9:1)was given by intratumoral injection at 30 min before ablation in the PEI+HIFU group,while 0.9% physiological saline 10mL was replaced in the simple HIFU group.The ablation energy efficiency factor(EEF)and irradiation time were compared between the two groups.Results The ablation EEF in the PEI+HIFU group and the simple HIFU group were (13.82+4.26)J/mm3 and (25.63+6.31)J/mm3 respectively,the PEI+HIFU group was significantly lower than the simple HIFU group (P <0.05);the irradiation time were (1 468.28+253.21)s and (2 352.56+463.34)s respectively;which in the PEI+ HIFU group was significantly shortened (P <0.05).Conclusion PEI can enhance the HIFU ablation energy deposition and improve the efficiency of HIFU for treating unresectable primary liver cancer.

The clinical application of arthroscopic minimally invasive treatment of shoulder joint disease technology has become a routine,and it has been widely carried out around the world.Compared with the traditional open surgery,it only needs to establish a few channels in the shoulder and then the diagnosis and treatment of the structure under the acromion and glenoid joint internal lesions can be completed through the arthroscopic technique under direct vision,of course,including local collection of pathological specimens.Shoulder arthroscopic surgery has the advantages of simple operation technique,small economic burden of patients,small tissue trauma,quick recovery and high accuracy of disease diagnosis.At present,there are two main options for shoulder arthroscopy:the beach chair position (BCP) and the lateral decubitus position (LDP).The choice of surgical position for surgeons is closely related to the intraoperative operation,the risk of complications,the efficacy of surgery,and the cost of setting the posture.Shoulder arthroscopy of these two positions have their own advantages and disadvantages:in the BCP,the surgeon gets a better anatomical operation experience,if necessary,can be converted into open surgery at any time.Without continuous traction,upper limb nerve and vascular damage caused by traction can be avoid.But the incidence of cerebral ischemic events in patients may increase in the BCP.There is also possibility of the nerve damage of the pillow small nerve,great auricular nerve,lateral femoral cutaneous nerve and other nerves.In theory the risk of air embolism in the patients will increase in the BCP,and the cost of setting the position is also higher than the LDP.While in the LDP due to the patient's forearm continuous traction,the surgeon can get a more extensive operating space,and the occurrence of cerebral ischemic events is very rare.In the treatment of anterior shoulder instability after shoulder arthroscopic surgery,there is a lower recurrence rate in the LDP.The cost of setting the position is also significantly lower than the BCP.Of course,the disadvantages of the LDP is also obvious.In the LDP,the brachial plexus and other nerves or vascular injury may increase due to the continuous traction of the forearm.Meanwhile sustained traction in the LDP is also a risk factor for thrombosis,and so on.Therefore,there is still a debate about the optimal location of the shoulder arthroscopy.Many clinicians choose shoulder arthroscopic position based on their own experience and habits.
