?AlM:To explore the use of rigid gas permeable ( RGP ) contact lens, and its clinical effect and safety in the treatment of adult high and special type ametropia.
? METHODS: Totally 110 cases ( 185 eyes ) of Ophthalmology Center fitting of RGP from January 2010 to December 2012 were retrospective analyzed. According to the refractive error types, patients were divided into high myopia astigmatism group( 49 cases, 92 eyes), 36 cases (64 eyes) of keratoconus group, special ametropia group (25 cases, 29 eyes). Corrected visual acuity differences, adverse reactions of different temporal acuity and conventional frame in the three group were observed after wearing RGP.
?RESULTS:After wearred RGP, corrected visual acuity of high myopic astigmatism group was 4. 94 ± 0. 16, keratoconus group was 4. 98±0. 15, and special ametropia group was 4. 87±0. 19; they were significantly better than wearing frame mirror 4. 86±0. 23, 4. 79±0. 22, 4. 61±0. 27 and the differences were statistically significant (P<0. 05). After 3 and 6mo of wearing RGP, patients eyesight after RGP was better than that of wearing frame glasses ( P<0. 05 ) . As the astigmatism group, keratoconus group, special ametropia group wearing RGP, visual acuity after distribution were obviously better than the case when wearing frame glasses(P<0. 05).
?CONCLUSlON: Wearring RGP can correct adult high and special type ametropia than ordinary frame glasses, which avoid the occurence of dry eye, foreign body sensation, and easy fatigue. lt is worthy of clinical application.

Objective To evaluate the morphological changes of the small nerves in lower extremity with high-resolution ultrasonography in type 2 diabetes mellitus (T2DM). Methods 84 cases of T2DM patients were divided into four different groups according to TCSS score [group Ⅰ (0-5 point), group Ⅱ (6-8 point), groupⅢ (9-11 point), group Ⅳ (12-19 point)]. The ultrasonic feature of posterior tibial nerve, sural nerve and saphenous nerve were observed to observe the relationship between ultrasound findings and scoring. Results Abnormality rate admitted from ultrasound findings are as follows. In group Ⅳ, nerve abnormality rate was the highest, followed by group Ⅲ, group Ⅱ and group Ⅰ (P < 0.05). The major manifestations are obscure border between spineurium and peripheral tissue , nerve bundle mesh like structure disappearing , enlargement of posterior tibial nerve and sural nerve. There was no statistical difference in irregular abnormality rate (P > 0.05). The saphenous nerve epineurium abnormality increased in group Ⅱ and Ⅲ compared with group Ⅰ and Ⅳ(P <0.05). Abnormality rate of 3 neural ultrasound decreased in line with sural nerve, posterior tibial nerve and saphenous nerve. Conclusions Certain correlation was observed between TCSS and never ultrasonic feature in T2DM patients. The higher TCSS scores is, the greater chance of presence of abnormal sonographic features of nerves will be. The sural nerve abnormality was higher than others.

Objective To test the safety and efficacy of using Botulinum Toxin Type A(BTX-A)in the treatment of chronic daily headache(CDH). Methods Thirty-eight patients in the treatment group injected BTX-A 50 U at 10 positions at the muscles including frontalis, temporalis, splenius capitis and occipitalis. Forty-four patients in the control group were given 2% lidocaine 3 ml plus prednisolone acetate 75 mg(2 ml)at the same muscles sites as in the treatment group. Frequency of headache, headache intensity(evaluated by visual analogue scale, VAS), quality of life(by WHO Qol-8 questionnaire)and adverse reactions were assessed on 0, 30, 60, 90 days after the treatment. Results At follow-up of 30,60, 90 days, the number of headache days per month reduced in both groups. BTX-A group had 14. 0 ±7.8, 13. 0 ±6. 8 and 13.0 ±6. 4 days per month, while the control group had 19. 0 ±6. 1, 21.0 ±6. 1 and 21.0 ±5.8, days at the follow-up of 30, 60 and 90 days, respectively, showing significant difference in the two groups(Z = 2. 895, 4. 544 and 4. 878, all P ＜ 0. 01). At 30 days, VAS scores in the treatment and control groups were 3.6 ± 1.5 and 3. 8 ± 1.3 respectively, showing no significant difference(Z = 1. 254,P =0. 210); At 60 days and 90 days, VAS scores in the BTX-A group were 3.2 ± 1.5 and 3. 1 ± 1.6 respectively, and in the control group were 4. 7 ± 1.3 and 5.0 ± 1.5 respectively, showing significant difference(Z =4. 950 and 5. 096, both P =0. 000). Quality of life in the two groups was slightly improved.After the treatment, 1 case(2. 6%)in BTX-A group occurred brow ptosis. The other patients didn't report any treatment related adverse events. Conclusion BTX-A is an effective and relative safe treatment in patients with CDH.

Circulating tumor cell (CTC) is a kind of malignant tumor cells shed from the primary tumor into the circulation caused by spontaneity or surgical operation and puncture. With the development of CTC analysis recently, the detection methods have been gradually diversified. As a new biomarker, CTC plays a significant role in the diagnosis, therapeutic effect monitoring and prognosis of tumors. This paper mainly introduces the enrichment and analysis technology of CTC, and explore the relationship between CTC and tumors.

Objective To investigate the correlation between hyperuricemia and obesity in children.Methods 316 children who went to the hospital for treatment of obesity were enrolled in the study as obesity group.Age and sex-matched children with normal body mass index(BMI)were randomly recruited as control group.Fasting venous blood samples were collected for the detection of serum uric acid(UA),glucose(GLU),total cholesterol(CHOL),triacylglycerol (TG),high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol(LDL-C).Results Compared with the control group,serum concentrations of UA,CHOL, TG and LDL-C were higher while HDL-C was lower in obese children,the difference was statistically significant(P <0.05 ).The detection rate of hyperuricemia in obese children was 24.68%,and in control group was 9.49%,the difference was statistically sig-nificant(P <0.05 ).Serum UA concentration was positively correlated with TG,CHOL and LDL-C,negatively correlated with HDL-C.Conclusion Obesity can lead to higher serum UA concentration and abnormal lipid metabolism.The level of serum UA was correlated with abnormal lipid metabolism.

In the embryonic period, myosin regulatory light chain (MYL2) plays a pivotal role in the development and function of the heart. A large number of studies have previously confirmed that the mutation of MYL2 gene, also known as MLC2, confers intimate associations with hypertrophic cardiomyopathy. MYL2 gene mutation impacts the structure and function of myosin, thereby leading to the occurrence and progression of hypertrophic and dilated cardiomyopathy as well as the following chronic heart failure. Importantly, MYL2 phosphorylation renders crucial effects in the processes of cardiac contraction, ventricular torsion and cardiac function.

Objective To investigate the role of NF-?B in acute lung injury following intracerebral hemorrhage. Methods Using stereotactic apparatus we infused autologous blood into the caudate nucleus to build up rat ICH model. A total of 35 male adult Wistar rats were randomly divided into sham-operation group(n=5) and hemorrhage group(n=30) that was subsequently divided into 6 subgroups (6 h,12 h,24 h,48 h,3 d,and 5 d,n=5). The inflammatory reaction degrees in the peripheral tissues of hematoma in the brain and lung were observed after HE staining. The levels of NF-?B p65 mRNA in the brain and lung were assayed using RT-PCR. The content of TNF-? and IL-1? in serum was determined by radioimmunoassay (RIA) method. Results Brain edema was obvious at 12 h after intracerebral hemorrhage and the inflammatory cells infiltration increased at 24 h and reached maximum at 48 h in the peripheral tissues of hematoma. Interstitial pneumonia and local emphysema appeared at 6 h and got to peak at 48-72 h,in which alveolar structure was significantly destroyed. In comparison with sham-operation group,the expression of NF-?B p65 mRNA began to increase at 6 h in brain and lung tissues (P

Percutaneous balloon mitral valvuloplasty (PMV) was performed in 100 cases with rheumatic mitral stenosis. In 94 ceases who successfully underwent the procedure, the mean left atrial pressure lowered from 22. 77?0. 84mmHg to 14. 40?0. 57 mmHg(P
