Objective To explore the protective effects on radiation injury of guinea pigs 'cochlea by sul-fotanshinoneⅡA sodium injection. Methods 20 guinea pigs(40 ears)were randomly divided into control group , radiotherapy(RT)group,radiotherapy and drug(RT+D)group and drug(D)group. The guinea pigs in the RT+D group and the D group were injected intraperitoneally with tanshinone on 2 days before the irradiation and last-ed for 7 days,while the guinea pigs in the control group and the RT group were injected intrapertoneally with equal amount of physiological saline at the same time. All the guinea pigs underwent audiologic test with DPOAE and ABR at different time points before and after the irradiation,which were d0,d7 and d8w. All pigs were sacrificed after the completion of the audiologic experimental and for histologic observation. Results After the irradiation, the DPOAE amplitudes of the guinea pigs in both RT group(F=1134.064,P<0.001)and RT+D group(F=664.185,P < 0.001)decreased significantly,but the range in the RT + D group was lower than in the RT group (P<0.001). The ABR threshold of the guinea pigs raised significantly in the RT group(F=12.228,P=0.002 <0.05),but not in the RT+D group(F=2.867,P=0.102>0.05). Histological examination showed that the dam-age degree of hair cells,stria vascularis and the spiral ganglion cells in the organ of Corti of the guinea pigs were lower than in the RT + D group,but higher in the RT group. Conclusion Sulfotanshinone ⅡA sodium injection can provide protection against radiation injury of guinea cochlea.

Objective To improve the effectiveness of deep venous catheter by nursing experience and effective methods in patients with deep venous catheter for chemotherapy. Methods Within 2 years in Xiangya Hospital, we had treated 326 cases of cancer patients who received chemotherapy by deep venous catheter. During the period of deep vein catheter chemotherapy, we paid attention to education and observation, and carried out the key points of nursing before and after deep venous catheterization. Results Out of 326 patients, 338 times of deep venous catheterization had been implemented, with a successful rate 99. 39% (324/326);the transient arrhythmia incidence rate was 3. 55%(12/338) in the process of catheterization;tube detached in 10-15 days incidence rate was 3. 07%(10/326), and the rate of puncture point red swelling with effusion was 2. 45%(8/326),which disappeared after proper treatment in 2-3 days. No patients had tube twisted, broken, embolism, phlebitis, catheter blockage, catheter-related bloodstream infections and other complications. All of tubes were drawn smoothly after being kept 16-120 days. Conclusions To ensure effective chemotherapy for patients with deep venous catheters, we should get familiar with deep vein puncture technology, professional skin care before and after catheterization, follow matters needed attention for the intravenous chemotherapy drugs, and strengthen the management of catheter.

Objective:To identify and analyze different proteins expression in the periosteum of congenital pseudarthrosis of the tibia (CPT) using tandem mass tags (TMT) proteomics.Methods:The samples were divided into three groups, namely CPT with neurofibromatosis type 1 (NF1) group (NF1-CPT group), CPT without NF1 group (nonNF1-CPT group) and control group (patients with open tibial fracture). A fold change ≥1.5 or ≤0.66 and P-value <0.05 was regarded as the threshold to screen differentially expressed proteins (DEPs). Subsequently, bioinformatics resources such as online tools DAVID and STRING were used to conduct GO annotation, KEGG pathways enrichment and protein-protein interaction (PPI) network with DEPs. Results:A total of 347 proteins differentially expressed in NF1-CPT group, 212 of which were up-regulated and 135 down-regulated. We identified 467 DEPs in nonNF1-CPT group, including 281 up-regulated and 186 down-regulated. Among of them, NF1-CPT group and nonNF1-CPT group shared 231 DEPs, except for HLA-DRB1 which increased in NF1-CPT group but decreased in nonNF1-CPT group. The remaining 230 DEPs showed the same expression trend in the two positive groups, including 117 up-regulated and 113 down-regulated. In particular, a total of 116 proteins were altered only in NF1-CPT group, including 94 up-regulated and 22 down-regulated. However, there were 236 proteins altered only in nonNF1-CPT group, including 164 up-regulated and 72 down-regulated. The results indicated that the pathogenesis of NF1-CPT was similar as nonNF1-CPT largely with a few differences. Finally, compared with nonNF1-CPT, there were 47 proteins changed 1.5-fold and P-value <0.05 in NF1-CPT group. Conclusion:The proteins expression in the periosteum of CPT is different from that of normal tibia. The expression of periosteal protein is also different between NF1-CPT and nonNF1-CPT. The present study will deepen our understanding of the pathogenesis of CPT in the protein level.

OBJECTIVETo determine the risk factor of HCC in Guizhou.

METHODSA group case-control study design was conducted between 762 cases and 798 controls in Guizhou province. The main related-factors were analyzed with unconditional logistic regression model and evaluated by odds ratio (OR) and 95% confidence interval (95% CI).

RESULTSThere are significant differences between cases and controls in regarding to cigarette smoking 210 (27.6%),non-alcoholic fatty liver disease 336 (44.1%), alcoholic liver disease 245 (32.2%), family history of HCC 141 (16.5%), alcohol consumption 300 (39.4%), HBV infection 436 (57.2%), pickled food 290 (38.1%), and economic status 5 years ago 420 (55.1%) in cases,and cigarette smoking 116 (14.5%),non-alcoholic fatty liver disease 160 (20.1%), alcoholic liver disease 101 (12.7%), family history of HCC 40 (5.0%), alcohol consumption 180 (22.6%), HBV infection 82 (10.3%), pickled food 225 (28.2%), and economic status 5 years ago 647 (81.1%) in controls, with OR of each variable was 3.520, 2.464, 4.330, 2.219, 2.451, 19.245, 6.212, 0.174 respectively, P less than 0.01.

CONCLUSIONHBV infection and pickled food were the most common risks for HCC in Guizhou. Alcohol consumption excessively and cigarette smoking may increase the risk too.

Objective: Previous research has explored a variety of mental disorders associated with Internet Gaming Disoder (IGD) and Social Media Addiction (SMA). To date, few studies focused on the network characteristics and investigated mood and sleep symptoms across SMA and IGD of adolescence at a group-specific level. This study aims to identify different characteristics of IGD and SMA and further determine the group-specific psychopathology process among adolescents. Methods: We conducted a cross-sectional study to recruit a cohort of 7,246 adolescents who were scored passing the cutoff point of Internet Gaming Disorder Scale-Short Form and Bergen Social Media Addiction Scale, as grouped in IGD and SMA, or otherwise into the control group. Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item, and Pittsburgh Sleep Quality Index were assessed for the current study, and all assessed items were investigated using network analysis. Results: Based on the analytical procedure, the participants were divided into three groups, the IGD group (n=789), SMA group (n=713) and control group (n=5,744). The edge weight bootstrapping analysis shows that different groups of networks reach certain accuracy, and the network structures of the three groups are statistically different (pcontrol-IGD=0.004, pcontrol-SMA<0.001, pIGD-SMA<0.001). The core symptom of SMA is “feeling down, depressed, or hopeless”, while IGD is “feeling tired or having little energy”. Conclusion Although IGD and SMA are both subtypes of internet addiction, the psychopathology processes of IGD and SMA are different. When dealing with IGD and SMA, different symptoms should be addressed.

Objective:To investigate the clinical and radiologic characteristics of children with congenital pseudarthrosis of the tibia (CPT) in a single center.Methods:This is a retrospective case series study. According to inclusion and exclusion criteria, clinical data of 497 children(507 limbs) with CPT who were treated at Department of Orthopedics, the Children′s Hospital Affiliated to Xiangya School of Medicine, Central South University from January 2011 to December 2020 were collected. Baseline data included gender, age at initial visit, age at onset of symptoms, accompanying symptoms, domicile, whether first treated at our hospital, and treatment-related information such as surgical or conservative treatment, surgical complications, etc., were extracted and analyzed using the health information system. Imaging data of the children, including Crawford classification, bilateral leg lengths, presence of fibular pseudarthrosis, and location of pseudarthrosis along the tibia segment, were analyzed using the Picture Archiving and Communication System. Data were compared using independent sample t test or χ2 tests. Results:Among 497 children with CPT, there were 305 males (61.4%) and 192 females (38.6%). The age at initial visit was (3.6±3.2) years (range: 0.1 to 16.2 years). Neurofibromatosis type 1 (NF1) symptoms were positive in 340 children (68.4%), and negative in 157 children (31.6%). Among NF1-positive children, those with symptoms onset before 1 year of age were significantly more than NF1-negative children (74.1%(252/340) vs. 66.2%(104/157); χ2=9.24, P=0.001), and the proportion of fractures (92.9%,316/340) was significantly higher than that in the NF1-negative group (84.7%,133/157) ( χ2=8.33, P=0.004). According to imaging data, Crawford type Ⅳ was the most common type, with 321 limbs (63.3%), followed by type Ⅱ in 100 limbs (19.7%), type Ⅲ in 54 limbs (10.7%) and type Ⅰ in 32 limbs (6.3%). Pseudarthrosis occurred in the proximal third of the tibia in 14 limbs (2.8%), in the middle third in 185 limbs (36.5%), and in the distal third in 308 limbs (60.8%). Seventy-four children (14.9 %) had associated fibular pseudarthrosis. The lateral proximal tibial angle was 86.91°±5.21°(range: 72.17° to 102.08°), and the lateral distal tibial angle was 87.27°±10.73°(range: 51.07° to 128.17°). A total of 421 children (84.7%) underwent surgical treatment with (3.1±2.4) surgeries performed per child (range:0 to 12 surgeries); 76 children (15.3%) received conservative treatment. Postoperative complications mainly included ankle valgus (77 cases), leg length discrepancy (71 cases),refracture (48 cases), osteomyelitis (11 cases), and hardware failure (10 cases). NF1-positive children underwent more surgeries than NF1-negative children ((5.1±2.2)times vs.(2.1±1.8)times; t=14.93, P<0.01). Conclusions:Crawford type Ⅳ is the most common type of CPT in children in this study. CPT predominantly occurs in the middle or distal third of the tibia. The majority of children with CPT experienced symptoms and were seen at outpatient clinics before the age of 3 years. The main surgical complications currently associated with CPT treatment are ankle valgus and leg length discrepancy. Compared with CPT without NF1, children with NF1-positive CPT tend to have earlier symptom onset and may require more frequent treatments.
