OBJECTIVETo study the healing effect of pneumoconiosis with tetrandrine and massive whole-lung lavage.

METHODSChoose 34 confirmed pneumoconiosis patients as drug treatment group and complex treatment group, and 17 tested workers as control group. Collected the content of TGF-beta1 and P III P which in these three investigated groups.

RESULTSDrug treatment group and complex treatment group of patients improved the clinical symptoms and lung function Compared with Pretreatment, the FVC, FEV1.0, FEV1.0/FVC, MVV was obviously higher than those before treatment (P < 0.05). Complex treatment group than in the drug treatment group increased more significantly (P < 0.05). The level of TGF-beta1 and P III P was reduced after complex treatment (P < 0.05). Moreover,the level of TGF-beta1 and P III P in these patients are lower than in those patients treated with tetrandrine combined with whole lung lavage (P < 0.05).

CONCLUSIONTetrandrine combined with whole-lung lavage could significantly retard the development of pneumoconiosis by lessening the TGF-beta1 and P III P in serum.

OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

Objective To explore the levels of water channel protein 4 (aquaporin-4,AQP-4) in the serum and the cerebrospinal fluid of patients with severe hand-foot-mouth disease (HFMD) and its clinical significance.Methods Children with the critical HFMD (clinical stage 3) admitted to Xuzhou Children's Hospital from February 2017 to November 2017 were recruited(critical group).In the same period,another 25 cases of common HFMD (central nervous system infection excluded in cerebrospinal fluid examination,common group),the other 25 cases of severe HFMD (clinical stage 2,severe group) were taken as the controls.The levels of AQP-4 in the serum and and cerebrospinal fluid were measured in all children and the levels of AQP-4 in cerebrospinal fluid were checked again in the critical and severe cases after treatment.The levels of interleukin-6 (IL-6),norepinephrine (NE) and neuron-specific enolase (NSE) in the serum were examined simultaneously and the correlation between them was analyzed.Results Before treatment,the levels of AQP-4 in the serum of critical group were (54.42 ± 19.86) μg/L,which were significantly higher than common group[(8.02 ± 1.59) μg/L] and severe group[(22.04 ± 8.14) μg/L] (F =36.684,P ＜0.01).Compared with before treatment,the levels of AQP-4 in the serum of critical and severe group were significantly lower after treatment (P ＜ 0.05).Before treatment,the levels of AQP-4 in the cerebrospinal fluid of critical and severe cases were respectively (9.81 ±2.27) μg/L and (8.58 ± 1.92) μg/L,which were significantly higher than common group (6.56 ± 1.79) μg/L (F =6.713,P ＜ 0.05).After treatment,the levels of AQP-4 in the cerebrospinal fluid of critical and severe cases were (8.41 ± 1.63) μg/L and (7.14 ± 1.69) μg/ L separately,which were significantly lower than before treatment (t =6.340,5.073,all P ＜ 0.01).The levels of IL-6,NE and NSE in serum were significantly different among the three groups (P ＜ 0.01).The above indicators were positively correlated with the levels of AQP-4 in the serum(r =0.734,0.810,0.729,all P ＜ 0.01)and were also positively correlated with AQP-4 in the cerebrospinal fluid (r =0.299,0.431,0.363,all P ＜ 0.05).Conclusion AQP-4 may participate in pathophysiological processes of HFMD.The levels of AQP-4 in serum can be used as an indicator for judging the severity and monitor prognosis of HFMD.

OBJECTIVETo observe the curative effect of HanFangJiaSu on pneumoconiosis.

METHOD71 patients with silicosis were divided into trial group and control group at random. The treating group (36 patients) was treated 90 days with HanFangJiaSu and The control group (35 patients) was treated 90 days with XiFeiNing. The silicosis with cough,chest complaint, dyspnoea and immune modulation were observed before treating and after treating. The effect was compared between the two groups.

RESULTTo compared with the group before treatment and the control group, the symptoms score of cough, chest complaint and dyspnoea in treated group was significantly decreased after treatment(P<0.05). The rate was decreased by 69.35% in treated group and 50.00% in controls, which showed the treatment in both groups was effective. The rate in treated group was significantly decreased more than in controls(P<0.05). There were 13 cases with respiratory tract infection and 2 cases with lung infection in treated group of which percentage were 36.11% and 5.55%, while 22 cases and 4 cases in control group of which percentage were 57.14% and 28.57%. There was a significant difference between the two groups (P<0.05). To compared with the group before treatment, the quantity of CD(4) in blood was obviously increased, while CD(8) was obviously decreased, which showed a significant increase of CD(4)/ CD(8), (P<0.05). To compared with control group, the quantity of CD(4) in treated group was obviously increased, while CD8 was obviously decreased, which also showed a significant increase of CD(4)/CD(8) (P<0.05). There was no significant difference with the concentration of immune globulin (IgG, IgA, IgM) between the groups before and after treatment.

AIMTo investigate the change of NMDAR1 (zeta 1) subunit expression in temple cortex, frontal lobe, hippocampus and cerebellum of three different group rat after 98 dB wide frequency noise exposure.

METHODSWestern Blot and RT-PCR technique, combined with auditory brainstem response (ABR) measurement.

RESULTS(1) Expressions of NMDAR1 (zeta 1) subunit in frontal cortex, temple cortex, hippocampus and cerebellum have no difference, but AD model rat is much weaker than the control group. (2) Expression of NMDAR2A (epsilon 1) in temple cortex for physiological saline groups rat have a mostly increase (plus noise), moreover, those are weakest expression in hippocampus. NMDAR1 (zeta 1) subunit in cerebellum have highest expression, moreover, it is weakest in temple cortex. (3) NMDAR1 (zeta1), NMDAR2A (epsilon 1) subunit expression in hippocampus for three groups rat have a down-regulation after adding noise. (4) NMDAR1 (zeta 1), NMDAR2A (epsilon 1) subunit mRNA expression in control group have no remarkable difference in different cortex. (5) Expressions of NMDAR2A (epsilon 1) in frontal temple cortex, hippocampus for AD model rat are less than that of other groups, weakest in cerebellum, weaker in frontal.

CONCLUSIONWide band frequency noise can reduce the expression of NMDAR1 (zeta 1) subunit in hippocampus and cerebellum of AD model rat, however, the way of regulation is not in the mRNA level. Wide band frequency noise can inhibit the expression of NMDAR2A (epsilon 1) in hippocampus, temple cortex of AD model rat, which has been regulated by mRNA level and have cortex area difference.

OBJECTIVETo investigate whether exogenous agmatine inhibits lipopolysaccharide (LPS)-induced activation and dysfunction of human umbilical vein endothelial cells (HUVECs) by modulating nuclear factor-κB (NF-κB) and MAPK signal pathways and the production of reactive oxygen species (ROS).

METHODSCultured HUVECs were treated with agmatine at the optimized concentration of 1.0 mmolγL, LPS (10 µgγmL), and LPS + agmatine, with or without pretreatment with the inhibitors of NF-κB (PDTC), p38 (SB203580), and ERK (PD98059) for 1 h. The levels of soluble vascular cell adhesion molecule 1 (VCAM-1), soluble intercellular adhesion molecule 1 (sICAM-1), soluble E-selectin and monocyte chemoattractant protein 1 (MCP-1) in the supernatant were determined using ELISA, and their mRNA expressions, along with heme oxygenase-1 (HO-1), and NAD(P)H: quinone oxidoreductase 1 (NQO-1), were assessed using real-time PCR. ROS production in the cells was determined using 2, 7-dichlorofluoresce in diacetate (DCFH-DA) as the fluorescence probe. The protein expressions of VCAM-1, ICAM-1, p65, phospho-p65 (p-p65), IκBα, p-IκBα, ERK, p-ERK, p38, p-p38, JNK, and p-JNK were detected using Western blotting.

RESULTSLPS stimulation for 6 and 24 h significantly increased the levels of sVCAM-1, sICAM-1, sE-selectin and MCP-1 in the supernatant, intracellular ROS production, and the mRNA expressions of these molecules (P<0.05). Intervention with 1 mmolγL agmatine, similar with pretreatment with p38, ERK and NF-κB inhibitors, obviously inhibited such effects of LPS in HUVECs (P<0.05). Agmatine significantly up-regulated the mRNA expression of HO-1 (P<0.05), inhibited LPS-induced phosphorylation of p38, ERK, nuclear p65 and cytoplasmic IκBα, and up-regulated the protein expression of cytoplasmic IκBα.

CONCLUSIONAgmatine inhibits LPS-induced activation and dysfunction of HUVECs by modulating NF-κB and MAPK signal pathways to down-regulate the expressions of adhesion molecules and chemokines and by up-regulating the expression of HO-1 to reduce ROS production.

OBJECTIVETo observe the results of total hip replacement with collum femoris preserving for the treatment of advanced stage of femoral head necrosis of youth.

METHODSFrom August 2002 to November 2009, 21 patients (28 hips) with advanced stage of femoral head necrosis were treated with total hip replacement with collum femoris preserving. Sixteen males (22 hips) and 5 females (6 hips) with an average age of 36 years (range from 26 to 51 years) were included. All patients were evaluated clinically using Harris score, the prosthesis components were assessed for position, loosening, bone resorption and other conditions with radiographs.

RESULTSNineteen patients (26 hip) were followed up for mean 5 years and 7 months (ranging 5 years and 3 months to 7 years and 1 month), 2 patients were missed. The average Harris score increased from the preoperative average 48.5 to 90.2. The leg-length discrepancy (the difference was less than 2 cm) occurred in 3 cases. No thigh pain and revision.

CONCLUSIONTotal hip arthroplasty with collum femoris preserving is one of the best choices for the treatment of advanced stage of femoral head necrosis of young patients with good midterm outcome.
