Objective To observe the clinical effect of mannatide treatment with burn infection. Methods 100 burn patients admitted to Sichuan Nanchong Central Hospital from May 2009 to July 2012 were randomly divided into control group and treatment group, each group had 50 cases. Both of two groups were given conventional treatment, treatment group were treated with intravenous mannatide,control group were injected recombinant human growth hormone. Results The average length of stay in treatment group was signiifcantly shorter than control group (P=0.042). The clinical total effective rate, serum IgA, IgG, IgM and other indicators of immune function were improved signiifcantly compared with control group (P=0.037). There was no statistical signiifcance in blood protein, transferrin, prealbumin, glucose, insulin, urinary sodium, urinary potassium, chloride and other indicators of patients between two groups. Conclusion Mannatide can effectively enhance immune function, promote wound healing, shorter hospital stay and improve the clinical efifcacy.

Objective To provide anatomical basis for the design of the V-Y advancement flap and investigate the morphological characters of the dorsal carpal perforators.Methods From August,2017 to October,2018,30 sides aduh specimens of hand were perfused with red latex.The following contents were observed under surgical magnifier:①The origin,courses,branches,and distribution of the dorsal carpal perforators.②The characters of dorsal carpal perforators in agreement with the antebrachial and dorsal metacarpal vascular net.Results The dorsal carpal vascular network was composed of deep vascular network (bone and joint network) and superficial vascular network (fasciocutaneous network).The deep vascular network was located at the deep aspect of the extensor tendons and was commonly formed by dorsal carpal branch of radial artery,dorsal carpal branch of anterior interosseous artery,ascending branch of the dorsal carpal perforator from the deep palmar arch,and dorsal carpal branch of ulnar artery.The superficial vascular network was located on the surface of the extensor tendons and was mainly formed by dorsal carpal branch of radial artery,dorsal carpal branch of ulnar artery,dorsal carpal branch of anterior interosseous artery,radial and ulnar myocutaneous branches of posterior interosseous artery,and the perforators from the deep vascular network.The 3rd and 4th perforators puncturing out from the ulnar and radial margins of the extensor tendon had a constant occurrence rate (100％) with an outer diameter of (0.7±0.3) mm and (0.6±0.2) mm,respectively,and a length of (1.1±0.4) cm and (0.9±0.4) cm,respectively.They were divided into the ascending branch,descending branch,and collateral branch.And finally anastomosis with antebrachial and dorsal metacarpal perforators.Conclusion The V-Y advancement flap based on the dorsal carpal perforators can be a good choice for restoring the dorsal metacarpal defects.

Objective To detect the expression of tumor necrosis factor-α-induced protein-8 like-3 (TIPE3) in colonic mucosa of patients with colon cancer,and to analyze the correlation between its abnormal expression and clinicopathological features of patients with colon cancer.Methods The expression of TIPE3 mRNA in 58 cases of colon cancer and tumor adjacent tissues was detected by realtime polymerase chain reaction (RT-PCR).The expression of TIPE3 at protein level in 83 cases of colon cancer and tumor-adjacent tissues was determined by SP immunohistochemistry.Nonparametric rank-sum test and chi-square test were performed for statistical analysis.Results The relative expression of TIPE3 mRNA in the colon cancer tissues was 0.719 (0.104 to 0.887),which was lower than that of tumor-adjacent tissues (4.770,1.732 to 6.800),and the difference was statistically significant (Z=-6.345,P＜0.05).There was no statistically significant difference in the expression of TIPE3 mRNA in colon cancer tissues between different gender,age and TNM stage (all P＞0.05).The expression of TIPE3 mRNA in group of patients with lymph node metastasis (0.113,0.061 to 0.375) was lower than group of patients without lymph node metastasis (0.489,0.327 to 0.956;Z=3.815,P＜0.01).The expression of TIPE3 mRNA of patients survived less than five years after operation (0.104,0.049 to 0.220) was lower than that of patients survived over five years (0.482,0.266 to 0.908;Z=-3.653,P＜0.01).The expression of TIPE3 mRNA of patients with recurrence after operation (0.188,0.091 to 0.493) was lower than that of patients without recurrence (0.409,0.233 to 1.010;Z=-2.431,P=0.015).The recurrence rate of TIPE3 mRNA high expression group in five years after operation was lower than that of TIPE3 mRNA low expression group (23.1％,6/26 vs 56.2％,18/32);and the difference was statistically significant (x2 =6.508,P＜0.05).The expression of TIPE3 at protein level of colon cancer tissues (44.6 ％,37/83) was lower than that of tumor-adjacent tissues (68.7 ％,57/83;x2 =8.004,P＜0.05).The expression of TIPE3 at protein level was not correlated with age and gender (both P＞0.05).The positive expression rate of patients at stage Ⅱ was higher than that of patients at stage Ⅲ (60.5％,23/38 vs 29.7％,1/37);and the difference was statistically significant (x2 =7.174,P＜ 0.05).The positive expression rate of TIPE3 in group of patients with lymph node metastasis was lower than that of groups of patients without lymph node metastasis (28.2％,11/39 vs 59.1％,26/44),and the difference was statistically significant (x2=7.983,P =0.005).Conclusions The expression of TIPE3 in colon cancer tissues is lower than that in tumor-adjacent tissues.Furthermore,it is correlated with lymph node metastasis,recurrence rate and survival rate.TIPE3 may be involved in the genesis,development,invasion and metastasis of colon cancer.

Objective: To screen the differentially expressed long non-coding RNAs(lncRNAs) by analyzing the related gene sequencing data of female non-smoking lung cancer patients in the database of The Cancer Genome Atlas (TCGA). Methods: The gene expression data and the corresponding clinical information of female non-smoking lung cancer patients were downloaded from the TCGA database. Then, the data were processed, integrated and analyzed with the R software package, and the differentially expressed genes were screened out. The prognosis was analyzed by the Survival package. Results: A total of 354 differentially expressed lncRNAs associated with female non-smoking lung cancer were obtained, of which 45 were down-regulated and 309 were up-regulated in tumor tissues. The prognosis analysis showed that the expression level of LINC01863 was positively correlated with the prognosis of female non-smoking lung cancer patients (P＜0.05), and that the expression levels of LINC02487, LINC01419 and DSCAM-AS1 were negatively correlated with the prognosis of female non-smoking lung cancer patients (P＜0.05). Conclusion The re-analysis on the high-throughput sequencing data in TCGA database obtains a large number of lncRNAs related to the development of female non-smoking lung cancer, which provides the potential new targets for the diagnosis and prognosis assessment of female non-smoking lung cancer.

Objective:To investigate the feasibility and reproducibility of using three-dimensional arterial spin labeling (3D-ASL) technique to evaluate the thyroid blood flow (TBF) in healthy adults and compare the difference in TBF between subjects with different gender and age.Methods:In this prospective study, 100 healthy adult subjects were enrolled from November 2018 to June 2019 in Chinese Academy of Medical Sciences Cancer Hospital, Shenzhen Hospital. All subjects received thyroid 3D-ASL MRI scanning, but several subjects were excluded from analysis for reasons including intolerance to examination ( n=1), overt artifacts ( n=11), abnormality detected in thyroid gland during conventional MRI ( n=15), resulting in 73 subjects included. Two attending radiologists independently evaluated the quality of ASL images and measured the TBF in upper, middle and lower poles of each lobe in thyroid gland bilaterally. Cohen’s Kappa was used to test the agreement in image quality between 2 radiologists, while intraclass correlation (ICC) analysis was implemented to evaluate the consistency in TBF measurements. Univariate variance analysis was used to compare the TBF in upper, middle and lower pole of thyroid gland unilaterally, and student t-test was performed to test the difference in TBF between two lobes, or in the same lobe but between different gender or age groups. Results:For image quality, 2 radiologists have good agreement (Kappa=0.753, P<0.001). In terms of TBF, consistency was moderate in the lower pole of left lobe between 2 radiologists (ICC=0.648, P<0.001), but good in the remaining parts of thyroid gland (all ICC>0.75, P<0.001). Unilaterally, TBF in the middle pole was significantly higher than those in the upper or lower pole ( P<0.001), but no significant difference was found between the upper and lower pole ( P>0.05). Regardless of upper, middle or lower pole, TBF in the right lobe was higher than the counterpart in the left lobe ( t=6.182, 6.294, 4.896, P<0.001). Between male subjects ( n=31) and female subjects ( n=42), no significant difference was found in the corresponding upper, middle or lower pole of thyroid lobe unilaterally ( P>0.05). As for age group, TBF in the middle pole of thyroid gland was higher in the middle age group (45-59 years old, n=12) than that in the young adult group (18-44 years old, n=61) ( t=3.868, P=0.003 for the left lobe, and t=2.647, P=0.022 for the right lobe), but no significant difference was found in the upper or lower pole of the unilateral thyroid lobe ( P>0.05). Conclusion:ASL can accurately measure blood flow perfusion in the thyroid gland with good reproducibility.

Objective:To investigate the total radioactivity in drinking well water around the Bayanwula uranium mine.Methods:Totally 174 samples of drinking well water and 5 samples of filtered well water from residential houses were collected during dry and wet seasons in 2020 around the Bayanwula uranium mine. Total α and total β radioactivity in dry season and wet season were analyzed for detrmining whether there were differences between them and the relation between total radioactivity with different locations away from the uranium center. The radioactivity in filtered drinking well water used in residential houses was also investigated. Radioactivity were measured and analyzed using low background alpha and beta radioactivity meters, and the data were analysed using SPSS analytical statistical method.Results:In the drinking well water around Bayanwula uranium mine, the activity concentrations of total α and β measured in dry season were 0.024-2.468 Bq/L with a mean of (0.605±0.507) Bq/L and 0.125-1.395 Bq/L with a mean of (0.420±0.235) Bq/L, respectively. The values measured in wet season were 0.049-2.988 Bq/L with a mean of (0.825±0.605) Bq/L for total α and 0.059-1.623 Bq/L with a mean of (0.506±0.265) Bq/L for total β, respectively. The average value of total radioactivity in water samples was lower within 10, 30 and 20 km of the uranium mine in the descending order.Conclusions:The radioactivity in well water around the Bayanwula uranium mine is high, with the total α and β in samples greater in wet season than in the dry season and without elevated levels as compared to the pre-mining background.
