?Dry eye ( DE) is a multifactorial disease of tear film and ocular surface. Inflammation in the ocular surface plays a main role in the pathogenesis of DE. Accordingly, inflammation and therapies that inhibit immune response may become topic for DE in recent years. Unfortunately, there are few studies about signaling pathway that has changed in ocular surface of DE. It is novel and there are few researches on how inflammation active signaling pathway and how it was regulated by signaling pathway on DE. This paper presents a review about inflammation active signaling pathway and its regulation on signaling pathway of DE.

Objective To investigate the relationship between subclinical hypothyroidism and ambulatory blood pressure in the patients with menopause hypertension .Methods 45 menopause hypertensive patients complicated with subclinical hypothyroidism (group A)and 58 menopause hypertensive patients(group B)were studied .Systolic blood pressure ,diastolic blood pressure ,height , body mass ,urea nitrogen ,serum creatinine ,uric acid ,fasting plasma glucose ,blood lipid level ,thyroid function and 24 hours ambula-tory blood pressure were measured .Results The levels of diastolic blood pressure ,24 hours diastolic blood pressure were higher in group A than those in group B[(89 .76 ± 11 .54)mm Hg vs .(80 .18 ± 10 .37)mm Hg ,(81 .05 ± 10 .45)mm Hg vs .(75 .46 ± 8 .73) mm Hg ,P<0 .01] .SBP and DBP nocturnal dipping were lower in group A than those in group B [(6 .43 ± 3 .56)% vs .(10 .35 ± 7 .63)% ,(8 .49 ± 6 .35)% vs .(13 .02 ± 8 .92)% ,P<0 .01] .The proportion of non-dipper patients was higher in group A than that in group B(62 .22% vs .39 .66% ,P<0 .05) .Multiple linear regression analysis showed that diastolic blood pressure decreased with the increasing of age ,and increased with the increasing of serum thyrotropin level .Nocturnal dipping decreased with the increasing of BMI and serum thyrotropin level .Conclusion Thyroid function tests should be performed in menopause hypertensive patients with poorly controlled diastolic blood pressure and non-dipping ,which contributes to the diagnosis of hypertension etiology .

Objective To investigate the function of serum soluble intercellular adhesion molecule-1(sICAM-1) in acute pancreatitis(AP).To study the significance of continuous monitoring sICAM-1 in differential diagnosis of AP.Methods A total of 60 patients were investigated;36 patients with acute edematous pancreatitis(AEP),and 24 with acute haemorragic necrotic pancreatitis(AHNP).The concentrations of sICAM-1 in the patients' serum were measured serially over a period of 7d by enzyme-linked immunosorbent assay(ELISA).Results There was significant difference between AEP group and AHNP group(P

Objective To investigate the effects of supplementing qi and activating blood circulation method(YQHX) on platelet inhibition rate and platelet membrane glycoprotein in elderly patients with unstable angina pectoris undergoing percutaneous coronary intervention(PCI).Methods Totally 177 elderly patients with unstable angina(qi deficiency and blood stasis syndrome) pectoris were randomized into two groups:90 cases in the treatment group and 87 cases in the control group.Both groups received conventional western medicinal treatment,for 14 days but YQHX was added to the treatment group.Platelet inhibition rate and platelet membrane glycoprotein were measured before and 14 days after treatment.Results After 14 days of treatment,the platelet inhibition rates induced by arachidonic acid (AA) and adenosine diphosphate (ADP) were significantly increased in the treatment group in comparison to pre-treatment and to control group respectively(P＜0.01).The prevalence of aspirin and clopidogrel resistance were lower in the treatment group than in the control group(8.9％ vs.21.8％,11.1％ vs.25.3％,both P＜0.05).After 14 days of treatment,the expression rates of CD62p,CD63 and PAC-1 were significantly lower in the treatment group than in pre-treatment and control group respectively (P＜0.01).Conclusions YQHX might effectively inhibit the platelet function and reduce the prevalence of aspirin and clopidogrel resistance in elderly patients with unstable angina pectoris undergoing the percutaneous coronary intervention.

AIM:To observe the clinical effects of 23-gauge (23G) transconjunctival sutureless vitrectomy for idiopathic macular hole.
METHODS: In this retrospective study, 28 eyes of 28 consecutive patients who underwent 23 - gauge transconjunctival sutureless vitrectomy for idiopathic macular hole between January 2013 and October 2013 in our hospital were evaluated. The follow-up time was 3-12mo. The operation effects were analyzed.
RESULTS:The macular hole was closed in 27 eyes of 28 eyes which underwent 23G transconjunctival sutureless vitrectomy and not closed in 1 eye after surgery. Best-corrected visual acuity at postoperative 1, 3mo was significantly improved compared to pre-operation (χ2=8-65, P=0. 003;χ2=10. 33, P=0. 001). The macular hole was closed as shown by OCT. Intraoperative incision was sutured in 5 cases ( 18%) . There was no statistically significant difference in intraocular pressure between pre-operation and post - operation. No post - operative complications such as endophthalmitis, retinal detachment, vitreous hemorrhage came up.
CONCLUSION: 23G transconjunctival sutureless vitrectomy is observed to be safe and effective technique in the treatment of macular hole. It is therefore our preferred system for straightforward macular surgery.

Aim To observe the influence of emodin on bleomycin-induced pulmonary fibrosis in rats, and explore its protective mechanisms. Methods Sixty SD rats were randomly divided into normal control group, sham operation group, model group, low-dose inter-vention group, high-dose intervention group and pred-nisone group. Each group included 10 animals. Rats in the latter 4 groups were intratracheally administered with bleomycin to establish pulmonary fibrosis model. From the second day, rats in low-and high-dose inter-vention groups were intragastrically treated with 2 mL of 20 and 80 mg · kg-1 emodin, respectively. Predni-sone group were intragastrically administrated with 2 mL of 5 mg·kg-1 prednisone acetate. However, con-trol and model groups were treated with 2 mL of normal saline. All rats were sacrificed on day 28. Pulmonary tissues were then removed, and HE and Masson stai-ning were performed. The contents of hydroxyproline ( HYP ) , malondialdehyde ( MDA ) , superoxide dis-mutase ( SOD) , glutathione-peroxidase ( GSH-Px) and catalase (CAT) in pulmonary tissues were measured. Serum concentrations of tumor necrosis factor-α ( TNF-α) , interleukin ( IL )-6 and IL-17 were detected by enzyme linked immunosorbent assay ( ELISA ) . The expression of Kelch-like ECH-associated protein 1 ( Keap 1 ) , nuclear factor-erythroid 2-related factor 2 (Nrf2) and nuclear factor-κB (NF-κB) p65 in pulmo-nary tissues was analyzed using Western blot. Results The pulmonary inflammation and fibrosis in low-and high-dose intervention as well as prednisone groups was significantly improved when compared with model group ( P<0. 05 , 0. 01 ) . In comparison with normal control group or sham operation group, pulmonary HYP and MDA contents, Nrf2 and NF-κB p65 expression levels in the nucleus, and serum concentrations of TNF-α, IL-6 and IL-17 were increased ( P <0. 01 ) , but pulmonary SOD, GSH-Px and CAT contents and Keap 1 expression levels in the cytoplasm were de-creased ( P <0. 01 ) in model group. Upon treatment with low-and high-dose emodin or prednisone, pulmo-nary HYP and MDA contents, Keap 1 expression levels in the cytoplasm, NF-κB p65 expression levels in the nucleus , and serum concentrations of TNF-α, IL-6 and IL-17 were reduced while pulmonary SOD, GSH-Px and CAT contents and Nrf2 expression levels in the nu-cleus were enhanced as compared to model group ( P<0. 01 ) . The above indicators were significantly im-proved in high-dose intervention and prednisone groups compared with low-dose intervention group ( P <0. 05). Nevertheless, There was no significant differ-ence between high-dose intervention group and predni-sone group ( P >0. 05 ) . Conclusion Emodin may protect against rats with pulmonary fibrosis by enhan-cing antioxidative ability and inhibiting inflammatory response.

Objective To study the combined effect of chlorotoluron and atrazine on the testis of mice. Methods Kunming mice were divided into groups and treated with chlorotoluron and atrazine alone or in combination by gavage at different doses for 25 consecutive days. Microscope and electron microscope were used to observe the morphological changes. Results The herbicides used alone or in combination, at all the test doses, caused the morphological changes in degrees in the testis. Under the light microscope, seminiferous epithelium arrayed loosely and disorderedly, spermatogenic cell shed, and layers lessened compared with the control group. Under the electron microscope, mitochondria in the seminiferous epithelium appeared vacuolated, karyotheca swelled, bent and the function of sustentacular cell declined. Compared with alone use groups, the pathological changes were more serious in combination use groups. Conclusion Chlorotoluron and atrazine can produce a combined toxic effect on the testis of mice.
