AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

OBJECTIVE: To study the expression of interferon-λ1 (IFN-λ1) in respiratory epithelial cells in children with human rhinovirus (HRV) infection. METHODS: Sputum samples and nasopharyngeal swabs were collected from the children who were hospitalized due to acute respiratory infection from February to October, 2017. Bacterial culture was performed, and nucleic acid test was performed for 11 respiratory pathogens. A total of 90 children with positive HRV alone were enrolled as the HRV infection group, and 95 children with positive respiratory syncytial virus (RSV) alone were enrolled as the RSV infection group. A total of 50 healthy children who underwent outpatient physical examination during the same period of time and had negative results for all pathogen tests were enrolled as the healthy control group. Nasopharyngeal swabs were collected from all groups, and quantitative real-time PCR was used to measure viral load and the mRNA expression of IFN-λ1. RESULTS: In the HRV infection group, there was no significant difference in the mRNA expression of IFN-λ1 between boys and girls and across all age groups (P>0.05). In the HRV infection group, there was no correlation between the mRNA expression of IFN-λ1 and HRV load (P>0.05). The mRNA expression of IFN-λ1 in the HRV infection group was significantly higher than that in the healthy control group (P<0.05), but significantly lower than that in the RSV infection group (P<0.05). CONCLUSIONS HRV can induce the expression of IFN-λ1 in respiratory epithelial cells, suggesting that IFN-λ1 may play an important role in anti-HRV infection in children.

OBJECTIVETo evaluate the advantages of combination therapy with interferon-alpha plus nucleoside analogue-lamivudine or HBV vaccine in children with HBeAg positive chronic hepatitis B.

METHODSA total of 120 patients with HBeAg positive chronic hepatitis B were divided into three groups, 40 patients per group. Each group was treated with one of the following therapies respectively: Group A IFN-alpha 1b 10 MU/m2 three times per week (Tiw); Group B IFN-alpha 1b 10MU/m2 three times per week (Tiw) plus lamivudine 3 mg/kg for 6 months. Group C IFN-alpha 1b 10 MU/m2 three times per week (Tiw) plus HBV vaccine 30 microg one a month.

RESULTSThere was no significant difference in normalizing rate of ALT among the three groups at end of treatment. There was more significant difference in negative rate (seroconversion) of serum HBV DNA and HBeAg in group B than group A and group C (P less than 0.05).

CONCLUSIONThe combination therapy of IFN-alpha 1b plus lamivudine seemed to be more effective than the therapy with IFN-alpha alone and the combination of IFN-alpha and HBV vaccine.

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

Objective To evaluate the clinical effects and safety of heparin injection on hemiplegia following urokinase thrombolysis for acute ischcmic cerebral infarction. Methods Fifty-six patients with acute cerebral infarction matched the standards which could be treated with urokinase thrombolysis in our department from January 2004 to January 2008. Among the 56 patients, 36 cases with hemiplegia in 2 h after thrombolysis got their muscle force recover over Ⅲ scale. Then 36 cases were divided into the treated group and control group randomly; 18 cases in the treated group were treated by heparin sodium 1000 U/h intravenously for 5 d. They were monitored for their activated partial thromboplastin time (aPTT) and the injected heparin speed was regulated according to their aPTT to keep their aPTT between 1.5 to 2 times of the control value. The 18 cases in the control group were given oral aspirin 0.1 daily, 24 h after thrombolysis. The 2 groups were compared in the case numbers of hemiplegia reoccurrence and cerebral hemorrhage within 7 d and the National Institutes of Health Stroke Scale (NIHSS) scores. Results Though there were 5 cases with asymptomatic hemorrhagic conversion, there was no hemiplegia case again in the treated group. In the control group, 5 cases suffered from hemiplegia again and 2 cases asymptomatic hemorrhagic conversion. There were less cerebral infarction in the treated group than the control group after 14 d by brain CT. The neurological deficit improvement in the treated group was more efficient in the treated group than in the control group in 14 d. Conclusion The application of heparin for the prevention of hemiplegia in the patients with acute cerebral infarction with muscle recovery after urokinase thrombolysis is safe and effective and shows obvious clinical value when their aPTT is remained 1.5-2.0 times of the normal level.

OBJECTIVETo investigate if the interaction between TGF-beta1/Smad pathway and ERK pathway in vascular smooth muscle cells exists.

METHODSThe rat arota was removed. The primary VSMC were isolated and cultured in vitro, then the VSMC were divided into four groups: (1) control group, (2) (TGF-beta1 group, (3) ERK blocking agent group, (4) TGF-beta1 + ERK blocking agent group. The expression of Smad2/3, ERK1/2 proteins, the content of phosphorylated ERK1/2 and Smad2/3 proteins were detected by Western blot, and the expression of Smad2/3 mRNA was detected by reverse transcription-polymerase chain reaction(RT-PCR) .

RESULTS(1) In contrast to control group, the content of phosphorylated Smad2/3 and phosphorylated ERK1/2 proteins in TGF-beta1 group was increased (P < 0.05), that in ERK blocking agent group was decreased (P < 0.05). There was no difference between control group and TGF-beta1 + ERK blocking agent group. Compared with TGF-beta1 group, the contents of phosphorylated Smad2/3 and phosphorylated ERK1/2 proteins in TGF-beta1 + ERK blocking agent group was decreased (P < 0.05). There was no difference in the expression of Smad2/3 and ERK1/2 proteins among different groups. (2) There were no differences in expression of Smad2 and Smad3 mRNA among different groups.

CONCLUSION(1) TGF-beta1 can induce Smad2/3 proteins to be phosphorylated dependent on the activated ERK pathway. (2) ERK pathway does not effect the expression of Smad2/3 at the level of protein and mRNA.
