ObjectiveTo investigate the expression and clinical value of coiled-coil domain-containing protein 34 (CCDC34) in hepatocellular carcinoma (HCC), and to predict the role of CCDC34 in the development and progression of HCC. MethodsThe datasets of HCC were downloaded from The Cancer Genome Atlas (TCGA) to obtain the expression profile and clinical information of the CCDC34 gene. The bioinformatics method was used to analyze the expression of CCDC34 in HCC, its correlation with clinicopathological parameters, and its influence on prognosis. The gene set enrichment analysis (GSEA) was used to predict the possible pathways regulated by the CCDC34 gene in HCC. The independent samples t-test and the paired t-test were used for comparison of continuous data between two groups; the Kaplan-Meier method and the log-rank test were used for survival analysis; the Cox proportional-hazards regression model analysis was used to investigate the influencing factors for prognosis. P＜0.01 was the standard for judging significant enrichment in GSEA, and the false discovery rate was ＜0.05. ResultsIn TCGA database, CCDC34 was highly expressed in tumor tissue, and there was a significant difference in the expression of CCDC34 between patients with different TNM stages and tumor grades (t=2.118 and 3.622, P=0.035 and P＜0.001). The patients with high expression of CCDC34 had a significantly shorter overall survival time than those with low expression (χ2=21.716, P＜005). The multivariate Cox regression analysis showed that the expression of CCDC34 （HR＝2.287,95%CI:1.312-3.987）and TNM stage(HR=1.943,95%CI:1.101-3.429) were independent risk factors for the overall survival time of patients with HCC (all P＜0.05). The enrichment of 8 pathway gene sets, including base excision repair and spliceosome, was observed in the samples with high expression of CCDC34 (P＜0.01, FDR ＜0.05). ConclusionCCDC34 may play a vital role in the development and progression of HCC and thus become a new prognostic indicator and a potential therapeutic target.

Objective To assess the quality of reporting randomized controlled trials published in Chinese journal of radiology from 2000 to 2005.Methods A manual search was performed and 22 checklists of CONSORT statements and other self-established criteria were applied.Results Six volumes and 72 issues were investigated.There were total trials of 236 in 2186 literatures,and finally 3 randomized controlled trials(RCTs)(1.27%)were identified.In the 3 RCTs,there were 3 trials with methods of randomization,1 with endpoints measurement,1 with multi-centre,but without the prior calculation of sample size,blind methods,statistically probability,participant flow,compliance and negative results.Conclusion The quality of reporting randomized controlled trials of interventional radiology has been improved,but it did not meet fully the CONSORT statement.

Objective To explore the changes of plasma angiotensinⅡ (AngⅡ) and cardiac function,and the curative effect of children with acute viral myocarditis (VMC) treated with captopril(CAP).Methods Concentrations of plasma AngⅡ were measured with radio-immunity and cardiac function was detected by Doppler echocardiography for the VMC group (n=60) before and after treatment [the CAP group (n=30), the routine group (n=30) and the control group (n=30)].Results 1. The level of plasma AngⅡ significantly increased and the contractive and diastolic function obviously declined in children with acute VMC. There was a significant difference between VMC group and control group, with a significant correlation between the level of AngⅡand the contractive diastolic function.2. Compared with the level before treatment, the level of AngⅡ decreased and the contractive function obviously ameliorated in two groups; the diastolic function obviously ameliorated in the CAP group and did not ameliorate in the routine group after treatment. In CAP group the level of AngⅡ and the cardiac function significantly improved; there were statistical differences between the two groups after treatment.Conclusions 1.The increase of the plasma AngⅡ was an important factor for decrements of the contractive and diastolic function in acute viral myocarditis.2.It could decrease the concentration of plasma AngⅡ and ameliorate cardiac function in children with acute VMC treated with captopril,which was an effective therapy for acute VMC.

OBJECTIVETo assess the feasibility and safety of laparoscopic anatomical hepatectomies (LAH) for intrahepatic bile duct stone.

METHODSLAH was performed in 14 patients with intrahepatic bile duct stone, while another 20 patients with intrahepatic bile duct stone underwent classical operation. Surgical time, blood loss, postoperative complications, and postoperative hospital stay were recorded.

RESULTSThe operations were successful in all 14 patients who underwent LAH. Surgical time was 190-420 mm [mean (259 +/- 134) mm]. Blood loss during operation was 220-1 000 ml [mean (454.5 +/- 314.2) ml]. No serious postoperative complications occurred. All these 14 patients were discharged with T dragin 7-14 days later, and the mean postoperative hospital stay was (9.2 +/- 3.4) days. In the classical operation group, the surgical time was 125-257 mm [mean (178 +/- 58) mm] and the blood loss was 210-1200 ml [mean (550.9 +/- 348.1) ml] All the patients were discharged with T dragin 9-25 days after operation, and the mean postoperative hospital stay was (13.4 +/- 4.7) days. Surgical time of LAH was longer than classical operation (P < 0.05). Rate of postoperative complications and postoperative hospital stay were decreased in LAH (P < 0.05, P < 0.01). The difference of blood loss during operation was no significance between LAH and classical operation (P > 0.05).

CONCLUSIONSLAH is feasible and safe for selected patients with intrahepatic bile duct stones. As a minimally invasive procedure, it can reduce surgical time, blood loss, hospital stay, and postoperative complications.

OBJECTIVE: To investigate clinical effects of minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate. METHODS: From February 2016 to March 2017, 32 patients with mid-lateral 1/3 clavicle fractures treated by minimally-invasive internal fixation with distal clavicular anatomic locking plate, including 24 males and 8 females with an average of (42.3±12.7) years old (ranged from 22 to 68 years old). According to Robinson classification, 6 patients were type 2A2, 18 patients were type 2B1 and 8 patients were type 2B2. No vessel and nerve injury occurred before operation. The time from injury to operation ranged from 0 to 6 days with an average of (3.1±1.4) days. Length of bilateral clavicule were compared before and after operation to evaluate fracture reduction. Constant score at 6 months after operation was applied to assess recovery of shoulder function. RESULTS: Thirty patients were followed up from 11 to 18 months with an average of (13.3±2.2 ) months. No vessel and nerve injury, implant failure, nonunion or delayed union occurred after operation, and facture wound healed at stage I, the time ranged from 8 to 12 weeks with an average of(10.2±1.1) weeks. Shortened length of clavicle decreased from(11.2±3.6) % before operation to (0.4±0.3)% after operation at 2 days. Ten patients removed internal fixation at 8 months after operation without re-fracture occurred after remove plate. Constant score increased from 23.53±5.21 before operation to 94.30±5.60 after operation at 6 months, and 26 patients got excellent results, and 4 good. Patients were satisfied aesthetic degree of scar and shoulder joint function. CONCLUSIONS Minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate, which has advantages of less trauma, rapid recover, less scar, could receive good clinical effects and not effect beauty.

Objective:To analyze the MRI features of hepatic epithelioid hemangioendothelioma (HEHE).Methods:The data of patients with HEHE managed in the Wenzhou People's Hospital of Zhejiang Province and the First Affiliated Hospital of Wenzhou Medical University from April 2000 to April 2019 were retrospectively analyzed. Among the 26 patients with HEHE, there were 12 males and 14 females, aged from 23 to 65 years (average 44.4 years). The quantity, size, shape and type of the lesions were observed and the MRI features were analyzed.Results:Of the 382 nodules detected by MRI in the 26 patients, the size varied from 0.5cm to 12.0 cm, with 16 nodules being more than 5.0 cm in diameter (average of 2.2 cm). Four patients with a single nodular type presented with low signal on T 1 weighted imaging (T 1WI), high signal on T 2 weighted imaging (T 2WI), high signal on diffused weighted imaging (DWI), and high central signal and low peripheral annular signal on apparent diffusion coefficient (ADC). After enhancement, the lesions presented with annular centripetal enhancement or continuous annular enhancement. Fourteen patients with multiple nodules had a total of 147 lesions, presenting with low signal on T 1WI, high signal on T 2WI, high signal on DWI, and high central signal and low peripheral annular signal on ADC. After enhancement, the lesions presented with annular centripetal enhancement and continuous annular enhancement. There were 24 lesions in 6 patients who had a " double-ring sign" , 21 lesions in 7 patients who had a capsule " shriveled sign" , 16 lesions in 7 patients who had a " lollipop sign" and 18 lesions in 5 patients who had an " intravascular sign" . There were 231 lesions in 8 patients of the fusion type. The lesions showed low signal on T 1WI, high signal on T 2WI , high signal on DWI, and high central signal and low peripheral signal on ADC. After enhancement, the lesions presented with flocculent or annular centripetal enhancement. In 8 patients, 87 lesions had a " target sign" , 55 lesions had a " lollipop sign" and 42 lesions had a capsule " shriveled sign" , and 36 lesions in 5 patients had an " intravascular sign" . Conclusion:MRI signs of HEHE have certain characteristics, such as lesions being distributed near the capsule, and fusing with each other; a " target sign" on T 2WI; a capsule " shriveled sign " ; and a " double-ring sign" , a " lollipop sign" , an " intravascular sign" in the portal phase. These features are helpful in diagnosing HEHE.

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD),201 PD patients were enrolled and underwent extensive clinical evaluations.Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI),and the Epworth Sleepiness Scale (ESS).It was found that poor sleep quality (77.11％) and excessive daytime sleepiness (32.34％) were commonly seen in PD patients and positively correlated with disease severity.Then 70 out of the 201 PD patients and 70 age-and sex-matched controls underwent a polysomnographic recording.The parameters were compared between PD group and control group and the influencing factors of sleep in PD patients were analyzed.The results showed that sleep efficiency (SE) was significantly decreased (P＜0.01),and sleep latency (SL) and the arousal index (AI) were increased (P＜0.05) in the PD group as compared with those in the control group.SE and total sleep time (TST) were positively correlated with the Hoehn and Yahr (H&Y) stage.There was significant difference in the extent of hypopnea and hypoxemia between the PD group and the control group (P＜0.05).Our results indicate that PD patients have an overall poor sleep quality and a high prevalence of sleep disorder,which may be correlated with the disease severity.Respiratory function and oxygen supply are also affected to a certain degree in PD patients.

Gouty arthritis is a type of metabolic rheumatic disease caused by autoimmune abnormalities. Currently, the use of Western medicine in the clinical treatment of gouty arthritis has been associated with a high risk of adverse reactions. Therefore, there is a growing interest in exploring therapeutic drugs from traditional Chinese medicine as a potential alternative. According to the theory of traditional Chinese medicine, gouty arthritis has been classified as damp-heat arthralgia syndrome. Shirebi granules has been found to have good clinical efficacy in treating gouty arthritis. However, its underlying pharmacological mechanisms remain unclear. To address this problem, the study first established the interaction network of candidate targets for Shirebi granules, which is used to treat damp-heat syndrome of gouty arthritis. Then, the key candidate targets of Shirebi granules for treating gouty arthritis with damp-heat syndrome were screened by calculating the topological features of the network nodes. Then, the functional mining of the key candidate targets revealed that the candidate targets of Shirebi granules may intervene in the biological process of inflammatory response and lipid metabolism through the crosstalk of Wnt/β-catenin signaling. To verify the effectiveness of Shirebi granules in treating gouty arthritis with damp-heat syndrome, a rat model was established. The results demonstrated that the granules significantly improved the severity of arthritis in rats with this condition, reduced joint inflammation, gait score, swelling index, increased mechanical pain threshold (P < 0.05), and reduced the content of serum inflammatory factors IL-1β, IL-6, and TNF-α in gouty arthritis rats with damp-heat syndrome (P < 0.01) gouty. It was also found that Shirebi granules effectively alleviated the symptoms of dampness heat syndrome such as local joint fever and dry mouth by reducing the temperature of the joints in acute gouty arthritis with damp-heat syndrome (AD) rats, increasing the threshold of heat pain, increasing water intake (P < 0.01), and inhibiting abnormal changes in the content of fatty acid oxidation related enzymes (P < 0.01). Western blot analysis showed that Shirebi granules increased the protein expression levels of Wnt and β-catenin (P < 0.01) while decreasing the protein expression of p65, p-p65 and PPARγ (P < 0.01) in rats with gouty arthritis and damp-heat syndrome. The results showed that Shirebi granules may reverse the "inflammation-immune" imbalance and lipid metabolism disorder by regulating the crosstalk of Wnt/β-catenin signaling, and play a role in alleviating the severity of the disease. This study provides a methodological reference for elucidating the pharmacological mechanisms of traditional Chinese medicine formulas. It also presents research ideas for the appropriate clinical use of Chinese patent medicines and the development of new clinical drugs for gouty arthritis therapy. The animal welfare and experiment procedures of this study were performed in accordance with the regulations of the Experimental Animal Ethics Committee of Experimental Research Center, China Academy of Chinese Medical Sciences (grant No. ERCCACMS11-2302-08).

Objective To study the effect of the EGF-L functional region containing human TN-R protein in prokaryocytes and anti-EGF-L serum on the cortical neuronsin vitro in rats. Methods The anti-EGF-L serum was obtained from the rabbits immunized with the protein of EGF-L, then combine with TN-R coat petri dish to prepare various culture substrate.The effect on adhere,migrate and neurite outgrowth of neuron by differ culture substrate was observed. Results High concentration of antiserum against protein of EGF-Lwas successfully obtained from the rabbits,and it has no effect on the neuron when coated on petri dish as culture substrate with PLL in vitro,but can add the adhesive to the neuron,partly neutralize the inhibitory on the neuron neurite of TN-R.The antiserum can also allow the neuron with its neurite to migrate to the area coated with TN-R. Conclusion The anti-EGF-L serum can weaken the inhibitory on the neuron of TN-R in vitro,the function in vivo need further research,
