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 clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH).Methods:A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method,with 59 cases in each group.The observation group was intervened by balance-impact tuina therapy,while the control group was intervened by conventional tuina therapy,both for consecutive two weeks.The scores of visual analog scale (VAS),Oswestry disability index (ODI),quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment.The data were statistically analyzed.Results:After intervention,the total effective rate was 96.6％ in the observation group versus 91.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The VAS and ODI scores declined significantly after treatment in both groups (all P＜0.05),and the observation group was markedly lower than the control group (P＜0.05,P＜0.01).The QOL-C30 score increased significantly after treatment in both groups (both P＜0.05),and the observation group was markedly higher than the control group (P＜0.05).The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P＜0.05,P＜0.01).Conclusion:Compared with the conventional tuina therapy,the balance-impact tuina therapy shows advantage in lessening pain,improving the function and enhancing the quality of life in the treatment of LIDH,and it has a lower relapse rate.Thus,this therapy is worth promoting in clinic.

Objective To investigate the effect of Xinma Granules on respiratory mucosal immune function in chronic asthmatic mice.Methods Fifty female BALB/C mice were randomly divided into normal group,model group,low-dose Xinma Granules group,high-dose Xinma Granules group and Dexamethasone group,with 10 mice in each group.Except for the normal group,the mice in the other groups were sensitized and challenged with ovalbumin(OVA)to establish a chronic asthma model.After corresponding treatment,the levels of secretory immunoglobulin A(sIgA)and immunoglobulin E(IgE)in bronchial lavage fluid were measured by enzyme-linked immunosorbent assay(ELISA).The pathological changes of lung tissue were observed by hematoxylin-eosin(HE)staining.The expression of E-cadherin in lung tissue was detected by Western Blot.Results HE staining showed obvious airway inflammation in asthmatic mice.The concentration of sIgA in the bronchial lavage fluid of the model group was lower than that of the normal group(P＜0.05);the concentration of sIgA in the high-dose and the low-dose of Xinma Granules groups and the Dexamethasone group was higher than that in the model group(P＜0.05);the concentration of IgE in bronchial lavage fluid of model group was higher than that of normal group(P＜0.05);the concentration of IgE in the high-dose and the low-dose Xinma Granules groups and the Dexamethasone group was lower than that in the model group(P＜0.05).The relative expression of E-cadherin protein in lung tissue of the model group was lower than that of the normal group(P＜0.05);the relative expression of E-cadherin protein in lung tissue of mice in the high-dose and low-dose Xinma Granules groups and Dexamethasone group was higher than that in model group(P＜0.05).The improvement effect on above various indexes in high-dose Xinma Granules group and Dexamethasone group were superior to that in low-dose Xinma Granules group(P＜0.05),the differences between the both groups were statistically insignificant(P＞0.05).Conclusion Xinma Granules may improve the airway mucosal immune function of asthmatic mice by improving airway inflammation,increasing the concentration of sIgA in the respiratory tract,and enhancing the expression of E-cadherin protein in the respiratory tract.

OBJECTIVEThe immunogenicity and protective efficacy of an experimental Campylobacter jejuni (C. jejuni) chitosan-DNA vaccines were evaluated in mice.

METHODSThe chitosan-DNA vaccines were prepared by embedding pcDNA3.1(+)-cadF and pcDNA3.1(+)-peblA with chitosan respectively. BALB/c mice were intranasally immunized in a four-dose primary series (7 d intervals) at doses of 60 microg chitosan-DNA vaccines each time. The comparative immunogenicities of nine formulations were assessed on the basis of the generation of antigen-specific antibodies in serum and intestinal secretions. Mice were attacked repeatedly through intragastric administration of C. jejuni HS:19 at the 8th week after the immunization and protective efficacy was determined by detecting the degrees of protection afforded against C. jejuni invaded.

RESULTSThe mice immunized with chitosan-DNA vaccines have generated high levels of IgA and IgG from the sera and IgA from the intestinal secretions and the P/N value went up to 20.58, 30.13 and 6.87 respectively. Meanwhile, the expression of intestinal SIgA increased correspondingly. Moreover the chitosan-DNA vaccines induced strongest level of protection in BALB/c mice against challenge with C. jejuni HS:19 strain and the protective efficacies was 93.70.

CONCLUSIONThe results of this study indicate that the chitosan-DNA vaccines could induce significant protective immunity against C. jejuni challenge in the mice model.

AIMTo approach the relationship between lung injury induced by shock/reperfusion and nitric oxide as well as the beneficial effect of taurine.

METHODSTwenty four rabbits were divided randomly into 3 groups (n = 8): control group, shock group, taurine group. The model of lung injury induced by shock/reperfusion was used. The activities of nitric oxide synthase (NOS), superoxide dismutase (SOD), the contents of malondialdehyde (MDA), nitric oxide products (NO2-/NO3-) in plasma and lung homogenate, lung wet/dry weight, lung water content, lung permeability index, and protein content in the pulmonary alveolar lavage fluid were measured. Meanwhile, pathologic samples treated routinely.

RESULTS(1) At 3 hours after reperfusion, the activities of SOD in plasma and lung homogenate decreased markedly, but the other indexes above mentioned were increased significantly compared with the control group (P < 0.01). (2) A close correlation was shown between MDA content and NO2-/NO3- content in plasma and lung. Furthermore, the content of NO2-/NQ3- in lung homogenate showed strong positive correlation with the lung injury parameters. (3) Taurine (40 mg x kg(-1) i.v.) could attenuate all the changes above mentioned at the same time points of reperfusion.

CONCLUSIONNO may play an important role in lung injury induced by shock/reperfusion. Taurine can ameliorate the lung injury, mechanism of which may be related to decreasing the generation of NO and anti-lipoperoxidation.

OBJECTIVETo compare two different procedures of colostomy in the laparoscopic- assisted abdominoperineal resection(LAPR), and to reduce the related complications of colostomy.

METHODSSixty- three cases with anorectal cancer undergone LAPR from June 2001 to December 2005 were registered and followed up. Circular stapler anastomosis with sigmoid colon and abdominal skin were applied on 61 cases of the colostomy, and 2 cases were hand sutured. All patients were assigned to group A and B. Thirty- seven cases received the procedure of colostomy through the rectus abdominis peritoneally in group A,other 26 cases through extraperitoneal tunnel and the rectus abdominis in group B.

RESULTSDescending colon, sigmoid colon and rectum were dissected using laparoscopic instruments in 63 cases. No conversion to open procedure and no operative death occurred in two groups of patients. There was no significant difference between two groups in mean operation time, but significant differences were found in the time of return of bowl function[A group (2.4 +/- 1.1)d vs B group (1.9 +/- 0.8)d,P < 0.05], duration of postoperative hospital stay [A group (19.9 +/- 7.8)d vs B group (14.5 +/- 3.9)d,P < 0.01] and stoma related complications(A group 29.4% vs B group 4.0%,P < 0.05). Postoperative hospital stay were shorter, and less colostomy related complications were found in group B.

CONCLUSIONColostomy through extraperitoneal tunnel and the rectus abdominis is a better procedure in LAPR, which can reduce the related complications of colostomy and shorten postoperative hospital stay.
