Abstract?AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.?METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.?RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P < 0. 05 ). The average lOP after treatment of 1d in the two groups were not statistically different (P>0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P<0. 05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference (P<0. 05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break- up time, was significantly superior to expose conjunctiva suture group (P<0. 05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group (P<0. 05).? CONCLUSlON: Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.

AIMTo investigate the effects of bradykinin on voltage-dependent sodium channel currents in rat dorsal root ganglion neurons (DRG).

METHODSWhole-cell patch clamp technique was used to determine sodium channel current.

RESULTSBradykinin at 0.01 - 10.0 micromol/L dose dependently increased the frequency of repetitive firing of DRG. Bradykinin at 0.01 - 10.0 micromol/L dose dependently enhanced the TTX-R sodium current, and had no effect on TTX-S sodium current.

CONCLUSIONMechanism underlying the inflammation induced by bradykinin is related to the TTX-R sodium channel.

OBJECTIVETo explore the effect of Yougui Recipe, a kidney-supplementing and yang-activating formula which on the behavioral changes of rat of steroid-induced avascular necrosis of the femoral head (SANFH).

METHODSThirty Wistar rats were involved and were randomly divided into the blank control group (group A), the model group (group B) and the Yougui Recipe group (group C). SANFH models were established by injection of colibacillus endotoxin and prednisolone intramuscularly. Group C was lavaged with Yougui Recipe (10 ml/kg), while group A and group B were lavaged with the same amount of saline. The behavior of catch force, independent activities, the tail suspension, field experiment and water cleans maze experiment were observed after 6 weeks.

RESULTSCompared with Yougui Recipe, rats in model group: catch force and independent activity decreases; the tail suspension activities was less time. In the desert field experiments, the total distance in 10 min movement reduced significantly. In the water maze experiment, incubation period of escape had a long time obviously, total distance of activities reduced.

CONCLUSIONYougui Recipe can relieve the ethologic change of rat model of steroid-induced avascular necrosis of the femoral head.

Sepsis is a potentially fatal condition characterized by the failure of one or more organs due to a disordered host response to infection. The development of sepsis is closely linked to immune dysfunction. As a result, immunotherapy has gained traction as a promising approach to sepsis treatment, as it holds the potential to reverse immunosuppression and restore immune balance, thereby improving the prognosis of septic patients. However, due to the highly heterogeneous nature of sepsis, it is crucial to carefully select the appropriate patient population for immunotherapy. This review summarizes the current and evolved treatments for sepsis-induced immunosuppression to enhance clinicians' understanding and practical application of immunotherapy in the management of sepsis.

OBJECTIVETo evaluate the efficacy and safety of thrombopoietin (TPO) on platelet engraftment in hematological malignancies patients after allogeneic haematopoietic stem cell transplantation (allo-HSCT).

METHODSOne hundred and twenty patients were enrolled in a multicenter, open-label, randomized, controlled clinical trial, and were randomized into 4 treatment groups following allo-HSCT. Group A was the control arm without TPO, while group B, C and D were trial arms with received 300 U×kg(-1)×d(-1) of TPO starting from day +1, +4 and +7, respectively. A total of 89 cases were evaluated, of which 22 cases in group A, 23 in group B, 20 in group C and 24 in group D. Efficacy evaluation (the time of platelet engraftment, the number of platelet transfusion) and safety evaluation \[adverse events, routine blood tests, liver and renal function, coagulation function and occurrence of graft-versus-host disease (GVHD)\] were observed.

RESULTSThe median platelet engraftment time in experimental groups (groups B, C and D) were on day (13.17 ± 2.89), day (12.15 ± 2.08), day (12.33 ± 1.76), respectively, and that in control group was on day (14.82 ± 5.05). There was statistically significant difference between two groups (P = 0.029), There were no statistically significant difference in the average amount of platelet transfusion, platelet engraftment time, and platelet nadir value among the 3 experimental groups. No significant adverse events were observed in experimental groups.

CONCLUSIONSTPO administration following allo-HSCT for patients with hematologic malignancies appears to shorten platelet engraftment time. TPO given starting from day +7 is effective and safe.

OBJECTIVETo study the difference in clinico-pathological features between IgA nephropathy (IgAN) and Henoch-Schonlein purpura nephritis (HSPN) in children.

METHODSThe medical data of 103 children with HSPN and 61 children with IgAN were retrospectively studied.

RESULTSThere were no significant differences in age, sex and disease course between the HSPN and IgAN groups (P>0.05). Clinical classification demonstrated that more severe conditions were found in the IgAN group than in the HSPN group and gross hematuria was more common in the IgAN group (P<0.05). Serum creatinine and cholesterol levels were higher in the IgAN group than in the HSPN group (P<0.05). Fibrinogen-related antigen deposition was more common in the HSPN group, while complement 3(C3) deposition was more common in the IgAN group. Interstitial fibrosis, tubular casts and tubular inflammatory infiltration were also more common in the IgAN group (P<0.05).

CONCLUSIONSSignificant clinico-pathological differences can be found between HSPN and IgAN in children, and these differences do not support a one disease entity hypothesis.

OBJECTIVETo investigate the significance of serum cholesterol and fibrinogen (Fib) in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome.

METHODSSixty-three children with primary nephrotic syndrome were divided into two groups according to their pathological types: minimal change glomerulopathy (MCG) (n=39) and focal segmental glomerulosclerosis (FSGS) groups (n=24). Serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C and Fib and 24-hour urinary protein excretion were retrospectively analyzed.

RESULTSSerum levels of TC, non-HDL-C, and LDL-C were significantly higher in the FSGS group than in the MCG group (P<0.05), but there were no significant differences in HDL-C, Fib and 24-hour urinary protein excretion between the two groups (P>0.05). According to the results of logistic regression analysis, high levels of LDL-C, non-HDL-C and TC were risk factors for FSGS (P<0.05). In patients whose proteinuria did not disappear after taking enough glucocorticoid for 4 weeks, the level of non-HDL-C was significantly higher in the FSGS group than in the MCG group (P<0.05); there were no significant differences in TC, LDL-C, HDL-C, and Fib between the MCG and FSGS groups (P>0.05).

CONCLUSIONSSerum cholesterol, especially non-LDL-C, is of great significance in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome. There is no sufficient evidence to support serum Fib as a marker for predicting glomerulosclerosis in these children.

The purpose of this study was to investigate the effects of vasonatrin peptide (VNP) on electrically-induced intracellular calcium ([Ca(2+)](i)) transient and mechanism of the effects in the cardiac myocytes. The [Ca(2+)](i) transient was measured with a fluoremetric method. The effects of HS-142-1, 8-Br-cGMP and methylene blue (MB) on [Ca(2+)](i) transient in cardiac myocytes were also determined. Isoproterenol (Iso) at 10(-10)~10(-6) mol/L augmented electrically-induced [Ca(2+)](i) transient dose-dependently, which was (13+/-8)% (P>0.05), (26+/-13)% (P< 0.05), (66+/-10)% (P<0.01), (150+/-10)% (P<0.01) and (300+/-25)% (P<0.01), respectively. These effects were blocked by an beta-adrenergic bloker propranolol (10(-6) mol/L). The effect of Iso (10(-8) mol/L) on [Ca(2+)](i) transient was attenuated in a dose-dependent manner by VNP at 10(-10)~10(-6) mol/L, which was (99+/-3)% (P>0.05), (96+/-2)% (P<0.05), (84+/-6)% (P<0.01), (66+/-3)% (P<0.01) and (62+/-3)% (P<0.01), respectively. 8-Br-cGMP (10(-7)~10(-3) mol/L) aslo attenuated 10(-8) mol/L Iso-induced [Ca(2+)](i) transient dose-dependent. The effect of VNP on [Ca(2+)](i) transient was almost abolished in the presence of HS-142-1 (2x10(-5) mol/L), an antagonist of the natriuretic peptide guanylate cyclase (GC) receptors. MB (10(-5) mol/L), an inhibitor of GC, not only blocked the effect of VNP in myocytes, but also augmented electrically-induced [Ca(2+)](i) transient. VNP and HS-142-1 themselves did not change the [Ca(2+)](i) transient in the cardiac myocytes significantly. But MB augmented the [Ca(2+)](i) transient in the cardiac myocytes significantly. These results suggest that VNP attenuates [Ca(2+)](i) transient induced by Iso. This effect is possibly achieved by binding VNP with the natriuretic peptide GC receptors in the myocytes, leading to an increase in intracellular cGMP.
