Allergic conjunctivitis is the most common type of allergic eye disease, and the incidence in children and adolescents is increasing year by year. Drug therapy can only relieve some symptoms and only in a short period, while allergen immunotherapy is currently a therapy that can significantly improve the symptoms of chronic allergy and the course of the disease. This method has been used abroad for many years but has yet to be reported in China. The author reviews the effective mechanism and clinical efficiency of allergen immunotherapy and provides a reference for the further clinical application in China.

Objective To assess the value of end-tidal carbon dioxide partial pressure (PETCO2) combined passive leg raising (PLR) test on volume responsiveness assessment in shocked patients post cardiac operation.Methods A prospective,self-controlled,and observational study was conducted.The shocked patients post cardiac operation undergoing complete mechanical ventilation admitted to Department of Critical Care Medicine of First Affiliated Hospital of College of Medicine,Zhejiang University from June 2014 to October 2015 were enrolled.PETCO2 and hemodynamic parameters including stroke volume variation (SVV),cardiac index (CI),mean arterial pressure (MAP) monitored by a pulse indicator continuous cardiac output (PiCCO) were determined before and after PLR and volume expansion (VE).Volume responsiveness was defined as an increase in CI (△ CI) of 15% or greater after VE,namely response group (△ CI ≥ 15%) and non-response group (△ CI < 15%).The value of PLR-induced PETCO2 change (△PETCO2 PLH) to predict volume responsiveness was evaluated by receiver operating.characteristic curves (ROC).Results Among the 41 patients enrolled,21 had volume responsiveness (response group),and 20 had no responsiveness (non-response group).After PLR,the changes in CI and PETCO2 were both significantly increased in the response group compared with non-response group [△ CI:(13.5 ± 4.6)% vs.(3.6± 3.5)%,△ PETCO2:(7.4 ± 3.4)% vs.(2.8 ± 2.5)%,both P < 0.05].△ PETCO2 PLR and baseline SVV were positively correlated with PLR-induced CI change (△ CI PLR) (r1 =0.50,r2 =0.38,both P < 0.05).VE-induced PETCO2 change (△ PETCO2 VE),baseline SVV and △ CI PLR were positively correlated with VE-induced CI (△ CI VE) (r1 =0.58,r2 =0.56 and r3 =0.84,all P < 0.01).The area under ROC curve (AUC) of △ PETCO2 PLR was 0.875±0.054 [95% confidence interval (95%CI) =0.769-0.981,P < 0.05].△ PETCO2 PLR ≥ 5.8% predicted volume responsiveness with sensitivity of 76.2% and specificity of 90.0%.AUC of △CI PLR was 0.933±0.036 (95%CI =0.862-1.000,P < 0.05).△CI PLR ≥ 10.4% predicted volume responsiveness with sensitivity of 81.0% and specificity of 90.0%.AUC of baseline SVV was 0.831 ±0.066 (95%CI =0.702-0.960,P < 0.05).Baseline SVV ≥ 12.5% predicted volume responsiveness with sensitivity of 85.7% and specificity of 75.0%.Conclusion The change in PETCO2 induced by PLR is a convenient,reliable and non-invasive indicator to predict volume responsiveness in shocked patients post cardiac operation with mechanical ventilation.

BACKGROUNDNajanalgesin, a toxin isolated from the venom of Naja naja atra, has been shown to exert significant analgesic effects in a neuropathic pain model in rats. However, the molecular mechanism underlying this protective effect of najanalgesin is poorly understood. The present study sought to evaluate the intracellular signaling pathways that are involved in the antinociceptive effect of najanalgesin on neuropathic pain.
METHODSThe antinociceptive properties of najanalgesin were tested in hind paw withdrawal thresholds in response to mechanical stimulation. We analyzed the participation of the mitogen-activated protein kinase p38, extracellular-regulated kinase (ERK), and c-Jun N-terminal kinase (JNK) by western blot analysis. This inhibition of JNK was confirmed by immunohistochemistry.
RESULTSThe phosphorylation levels of JNK (as well as its downstream molecule c-Jun), p38, and ERK were significantly increased after injury. Najanalgesin only inhibited JNK and c-Jun phosphorylation but had no effect on either ERK or p38. This inhibition of JNK was confirmed by immunohistochemistry, which suggested that the antinociceptive effect of najanalgesin on spinal nerve ligation-induced neuropathic pain in rats is associated with JNK activation in the spinal cord.
CONCLUSIONThe antinociceptive effect of najanalgesin functions by inhibiting the JNK in a neuropathic pain model.

OBJECTIVETo study the risk factors of male infertility.
METHODCase control study including 94 cases and control group with a ratio of 1 to 1.
RESULTSThe risk factors of male infertility were long time heavy smoking habit (OR = 3.45, 95% CI: 1.95 - 6.10), illegal sexual intercourse (OR = 7.29, 95% CI: 2.54 - 20.89), growing vegetable under plastic in higher temperature (OR = 6.73, 95% CI: 1.91 - 23.69), contact with benzene chemicals (OR = 20.53, 95% CI: 4.67 - 90.25) and having Ureaplasma urealyticum (Uu) infection (OR = 5.55, 95% CI: 2.28 - 13.53).
CONCLUSIONMale infertility was resulted from many factors repeatedly acting on men for long time. In order to prevent male infertility, issues as environmental pollution, occupational protection need to be improved while bad working condition and risky behavior should be changed.

AIM: To compare the distribution characteristics of axial sagittal front power(ASF), true net power(TNP), total corneal refractive power(TCRP)and the difference in back-front corneal radius ratio(B/F ratio)after cataract surgery.METHODS: A prospective study. A total of 156 patients(156 eyes)with age-related cataract who attend Weifang Eye Hospital for cataract surgery from December 2020 to May 2021 were collected. Pentacam was performed before operation and 3mo after operation to collect ASF, TNP and TCRP on 2, 4 and 6mm diameters rings and areas on the corneal apex and pupil-centered, as well as B/F ratio.RESULTS: 3mo after operation, there was no statistical difference in ASF on the 2mm diameters ring and area centered on the corneal apex compared with preoperative values(all P>0.05), however, the ASF values on the 4 and 6mm diameters rings and areas were significantly different from those before surgery(all P<0.05); There was no statistical difference in ASF on the 2mm diameters rings and areas centered on the pupil compared with preoperative values(all P>0.05). The postoperative values of TNP and TCRP on the 2, 4 and 6mm diameters rings and areas centered on the corneal apex and centered on the pupil were statistically different before surgery(all P<0.05). Preoperative, TCRP values were different between 2mm and 6mm and between 4mm and 6mm on both corneal apex and pupil-centered rings(all P<0.0167), TCRP values were all different between 2mm and 6mm diameters areas on corneal apex and pupil-centered(all P<0.0167); 3mo after operation, TCRP values were different on corneal apex and pupil-centered rings between 2mm and 6mm and between 4mm and 6mm diameters(all P<0.0167). While TCRP values on the corneal apex and pupil-centered areas were only different between 2mm and 6mm diameters(all P<0.0167). The preoperative B/F ratio of patients was 81.79%±1.87%, and the postoperative B/ F ratio of patients was 80.68%±2.23%(P<0.001).CONCLUSION: Corneal parameters of different diameters of rings and areas centered on the corneal apex and pupil before and after cataract surgery may change and differ, which should be taken into account when selecting the K value for intraocular lens calculation and individualizing the selection of IOLs based on corneal characteristics.

Purpose To oberve the dynamics of liver granuloma and the relative changes of Thl/Th2cytokine levels in mice infected with Schistosoma japonicum, and investigate the role of Th1/Th2 in S.japontcum granuloma formation and regulation. Methods Liver granuloma measurement were performedby histological examination and the ELISA were used for the quantitative determination of IL-2, IFNr andIL-4 in murine serum and spleen lymphocyte culture medium at 0,4,6,8,10 and 12 wk after infection.Results At 6 wk liver granuloma formation appeared and at 8 wk liver granuloma peaked. After 12 wk livergranuhoma diminished obviously. Meanwhile, at 4 - 6 wk IL-2, IFNr and IL-4 began to rise, at 8 wk thelevels of Th1 cytokines IL-2 and IFNγ peaked and then declined, and at 8 wk the levels of Th2 cytokines IL-4 were rapidly enhanced and increased obviously with a prolongation of the infection duration.Conclusions The Th1cytokines IL-2 and IFNγ were correlated well with S. japonicum granulomaformation and vigour, and the Th2 cytokines IL-4 might play an important role in down-regulating egggranuloma reaction at chronic schistosomiasis by inhibiting the Th1cytokines.
