OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

To investigate the epidemic and evolutionary trends of enterovirus (EV) in the external environment of Yunnan Province, China, molecular typing was performed on 4 EV strains that were isolated from environmental sewage in Yunnan. The VP1 region of isolates was amplified by RT-PCR using universal enterovirus primers, and the amplified VP1 region was sequenced for GenBank BLAST search and genotype analysis. The 4 EV strains were identified as ECHO7. Their nucleotide and amino acid homologies with the VP1 sequences of 68 ECHO7 strains retrieved from GenBank were measured by Mega software analysis. Our findings showed that ECHO7 strains from environmental sewage and population samples were in different evolutionary branches. These strains showed typical geographical and temporal differences; In addition, there were different transmission chains at the same time and in the same area. ECHO7 strains isolated from sewage water and patients with acute flaccid paralysis during the same period in Yunnan belonged to different clusters and evolved at different speeds. Special concerns are needed for this problem. Continuous molecular biological surveillance of human EV in the external environment of Yunnan will provide strong support for early warning of EV diseases.

BACKGROUND:During total hip arthroplasty, placement angle of acetabular prosthesis is significant for clinical curative effects. OBJECTIVE:To investigate the abduction angle and anteversion angle of acetabular prosthesis at different positions during total hip arthroplasty and related influential factors. METHODS:Thirty-five patients undergoing total hip arthroplasty were included in this study, containing 21 males and 14 females, at the age of 51-75 years old. Thesame patient at different positions underwent X-ray examination, including standing anteroposterior pelvis radiographic imaging, standing lateral radiographic imaging and supine anteroposterior pelvis radiographic imaging. Abduction angle and anteversion angle of acetabular prosthesis were measured. RESULTS AND CONCLUSION:(1) Abduction angle and anteversion angle at standing positionwere bigger than that at supine position (48.47°, 45.89°; 12.44°, 6.17°;P< 0.05). (2) The change in anteversion angle wasassociated with pelvic incidenceangleand pelvic tiltangle. The change in abduction angle was associated with pelvic obliquity. (3) The range of abduction angle (40±10)° and anteversion angle (15±10)° of acetabular prosthesis was identified as securityzone. (4) Results suggested that there were changes in acetabular abduction angle and anteversion angle between supine anteroposterior pelvis radiographic imaging and standing anteroposterior pelvis radiographic imaging after total hip arthroplasty. Acetabular angle was associated with pelvic obliquity, pelvic incidence and pelvic tilt.

OBJECTIVETo observe the clinical significance of nitric oxide (NO) and 8-isoprostane (8-isoPG) changes in exhaled breath condensate ( EBC) of acute respiratory distress syndrome (ARDS) patients after treated by Qingfei Decoction (QD).

METHODSTotally 48 ARDS patients receiving mechanical ventilation were equally assigned to the QD treatment group and the control group by random digit table. EBC specimens were collected by modified Ecoscreen breath condensate collector (German JAEGER Company) on the first day and the fifth day after confirmed diagnosis of ARDS. Concentrations of NO and 8-isoPG in EBC were measured by ELISA. The oxygenation index and APACHE II scores were recorded at the same time.

RESULTS(1) The fatality rate in the QD treatment group was lower than that in the control group (8.3% vs 37.5%, P < 0.05). (2) After treatment NO and 8-isoPG concentrations in EBC were lower in the QD treatment group (34.49 ± 5.67 µmol/L, 30.09 ± 7.89 ng/L) than in the control group (39.78 ± 9.27 µmol/L, 35.65 ± 8.90 ng/L; P < 0.05). (3) After treatment improved oxygenation index value was higher in the QD treatment group than in the control group (120.88 ± 35.16 vs 101.50 ± 37.70, P < 0.05). After treatment APACHEII scores was lower in the QD treatment group than in the control group (6.21 ± 3.51 vs 10. 26 ± 4.33, P < 0.05).

CONCLUSIONTreatment of ARDS patients by QD was favorable in controlling inflammation, alleviating lung injury, and improving clinical efficacy.

Background Statistic data revealed that different retinopathy of pre-term infants have different susceptibility to retinopathy of prematurity (ROP),which may be associated with polymorphism of vascular endothelial growth factor(VEGF) gene.Objective This study was to determine the association of polymorphisms of VEGF gene with the risk for ROP.Methods This research was approved by Ethics Committee of Hunan Children's Hospital,and written informed consent was obtained from the parents of patients.A prospective case-controlled study was designed.Ninety-nine ROP patients in Hunan Children' s Hospital and 88 pre-termed children without ROP were included from January,2006 to December,2009.Thirty-nine patients who received retinal photocoagulation or cryotherapy were included as the treatment group,and 60 untreated but spontaneously regressed ROP patients as the non-treatment group.No significant differences were seen in demography between with the ROP group and the without ROP group,or between the treatment group and the non-treatment group (all P＞0.05).2 mL of peripheral blood was collected for the extraction of DNA.Gene polymorphisms of VEGF-A+405 and VEGF-A936 were detected using the pyrosequencing method.Results No significant difference was found in the frequencies of the VEGF-A+405 gene polymorphisms between the ROP group and without ROP group (P =0.071,OR =0.675,95 ％ CI =0.444-1.026).Also no significant difference was found in the frequencies of the VEGF-A936 gene polymorphisms between with the ROP group and without the ROP group (P =0.118,OR =0.768,95 ％ CI=2.823-4.614).However,the frequencies of the VEGF-A+405 gene polymorphisms were significantly higher in the ROP treatment group than the non-treatment group (P＜0.01,OR--0.857,95 ％ CI =5.239-14.024),and VEGF-A936 gene polymorphisms was also significantly higher in the ROP treatment group than the non-treatment group (P =0.000,OR =3.609,95 ％ CI =0.711-0.829).Conclusions There is no association between the VEGF-A+405/VEGF-A936 single nucleotide polymorphism with the risk of ROP,but polymorphisms of VEGF gene may be correlated with the prognosis of ROP.The carrier of VEGF-A +405 /VEGF-A936 allele is more susceptible to ROP progression.

OBJECTIVE: To study the effect of early continuous blood purification (CBP) on the prognosis of children with septic shock. METHODS: A prospective analysis was performed for the children with septic shock who did not reach the 6-hour initial recovery target and/or had a fluid overload of >10%. According to the treatment time of CBP, they were divided into an early group with 30 children and a conventional group with 28 children. The two groups were compared in terms of the start time of CBP and 28-day mortality rate, as well as the related indexes in the children who were cured. RESULTS: The early group had a significantly earlier start time of CBP than the conventional group (P<0.05). There were 25 children cured in the early group and 22 cured in the conventional group, and there was no significant difference in 28-day mortality rate between the two groups (P>0.05). The children who were cured in the early group had significantly shorter correction time of lactic acid, urine volume, and fluid overload than those in the conventional group (P<0.05). The children who were cured in both groups had significant reductions in the percentages of T-lymphocyte subsets at the beginning (P<0.05); on reexamination on day 7, the percentages of T-lymphocyte subsets were increased and were higher in the early group than in the conventional group (P<0.05). The children who were cured in the early group had significantly shorter duration of CBP treatment, duration of mechanical ventilation, and length of stay in the PICU than those in the conventional group (P<0.05). CONCLUSIONS For children with septic shock who do not reach the 6-hour initial recovery target and/or have a fluid overload of >10%, early CBP treatment can quickly control the disease, shorten the course of disease, and accelerate immune reconstruction.

OBJECTIVETo explore the molecular mechanism of miR-124 suppressing the proliferation and invasion of gastric cancer cells.

METHODSSPHK1 3'UTR-luciferase vector was constructed and luciferase reporter gene assay was employed to examine the effect of miR-124 on luciferase activity. Human gastric cancer MGC-803 cells were transfected with miR-124 mimics, and then Western blot was performed to detect the expression of SPHK1 protein.

RESULTSLuciferase reporter vector system confirmed that SPHK1 was a target gene of miR-124. Western blot showed that the expression of SPHK1 protein was inhibited by miR-124. After transfection of miR-124 mimics or SPHK1 siRNA for 12 h, 24 h and 48 h, respectively, MTT assay showed that the A values of the three groups were significantly different (P < 0.05), and it was in a time-dependent manner. After transfection of miR-124 mimics or SPHK1 siRNA for 24 h, transwell invasion assay showed that the number of transmembrane cells was 54.6 ± 8.3 in the SPHK1 siRNA group and 47.8 ± 6.6 in the miR-124 mimics group, both were significantly lower than 100.6 ± 11.3 of the control group (P < 0.05), indicating that SPHK1 siRNA can slow down the invasion of MGC-803 cells.

CONCLUSIONmiR-124 can suppress the cell proliferation and invasion by targeting SPHK1 in gastric carcinoma.

OBJECTIVETo study the effect of arctiin on mouse podocyte epithelial-mesenchymal transition (EMT) induced by advanced oxidation protein products (AOPP).

METHODSMouse podocytes were stimulated by 200 µg/ml AOPP for 24 h in the presence of 50, 100, 200, and 400 µmol/L arctiin. The expressions of α-smooth muscle actin, Grp78 and CHOP were detected using Western blotting.

RESULTThe expressions of α-SMA, Grp78 and CHOP were inhibited by arctiin, showing a dose-dependent effect within a given range of arctiin concentration.

CONCLUSIONAOPP causes endoplasmic reticulum stress to induce EMT of mouse podocytes, and arctiin can decrease EMT by alleviating the stress. This finding sheds light on a new scope of research of renal fibrosis.
