Objective To seek a scalp venipuneture method with high success rate and less pain for patients. Methods Taking the rapid parallel straight method as the control group, and the rapid vertical straight method as the experimental group, 400 patients were randomly divided into the control group and the experimental group with 200 patients in each group. The success rate of two groups were counted, pain scores were got by VAS visual imitation assessment and the results undergoing statistical analysis. Results The success rate was 91.5% in the control group, and 99.5% in the experimental group. Distinguished sig-nificance existed in VAS visual imitation score. Conclusions The rapid vertical straight method is supe-rior to rapid parallel straight method in scalp venipuncture.

Background and purpose: Previous studies have confirmed that the expression of leucine-rich repeat-containing 3B (CLRRC3B) was significantly decreased in different human cancers, which was also associated with the migration and invasion of cancer cells. The aim of this study was to explore the potential mechanism of LRRC3B in the development of esophageal cancer. Methods: The LRRC3B expression was detected in 60 cancer tissues and 60 adjacent non-neoplastic tissues by immunohistochemistry. The mRNA and protein expression of LRRC3B in Eca109 and HEECs were detected using real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot, respectively. Eca109 cells with different treatments were divided into three groups:normal group, negative control group (transfected with pCMV6 plasmid), overexpression LRRC3B group (transfected with pCMV6-LRRC3B plasmid). Transwell assay was used to measure the migration and invasion of Eca109 cells in different groups. The protein levels of E-cadherin, N-cadherin, Vimentin and p-Akt were determined by Western blot. Results: The expression of LRRC3B in esophageal cancer tissues was lower than that of non-cancerous tissues, as well as the expression of LRRC3B in Eca109 was decreased compared with that of normal esophageal epithelial cell line HEEC. Overexpression of LRRC3B significantly inhibited Eca109 cells migration and invasion, upregulated the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin. Moreover, overexpression of LRRC3B significantly inhibited the phosphorylation of Akt in Eca109 cells. Conclusion: The expression of LRRC3B was decreased in esophageal cancer. Overexpression of LRRC3B can efficiently inhibit the EMT progression in esophageal cancer cells by suppressing PI3K/Akt signaling pathway.

Objective To investigate the effects of CNTN-1 on the invasion and migration of human esophageal cancer EC9706 cells and the possible mechanism.Methods The expression of CNTN-1 in human esophageal cancer EC9706 cells was measured by qPCR and Western blot.After transfection with CNTN-1 siRNA or CNTN-1, the cells were divided into control group, scrambled siRNA group, CNTN-1 siRNA group, pcDNA3.1-vector group and pcDNA3.1-CNTN-1 group.Cell proliferation, invasion and migration were respectively analyzed by BrdU assay and Transwell test.The expression of MMP-2 and MMP-9 were detected by qPCR and Western blot.Results The mRNA and protein expression of CNTN-1 were significantly upregulated in EC9706 cells.Compared with control, cell proliferation, invasion and migration, as well as the expression of MMP-2 and MMP-9 were significantly decreased by CNTN-1 siRNA, while they were increased by CNTN-1 overexpression (P<0.05).ConclusionsCNTN-1 can influence the invasion and metastasis of esophageal cancer cells through the regulation of the expression of MMP-2 and MMP-9.

Objective To investigate the prevalence of thyroid nodules(TN)among centenarians in Hainan province and explore the association between thyroid nodules and major chronic diseases.Methods A mixed cross-sectional study of questionnaire survey,medical examination including ultrasonography and laboratory examination were conducted in elderly who resided in Hainan province and aged 100 and over,the subjects who have signed consent and complete data in both basic information and medical examination were included in this study.Eight hundred and four centenarians were finally enrolled and data of them was analyzed to investigate the prevalence of thyroid nodules and to explore its association with common chronic diseases by comparing the prevalence of chronic conditions between groups with and without thyroid nodules.Results The overall prevalence of TN was 73.5%(591、804)and the prevalence of TN was significantly higher in female when comparing with male[75.1%(505、672)vs 65.2%(86、132)](P <0.001).No significant correlation was found between the prevalence of TN and major chronic diseases (P>0.05),however,the factors associated with dyslipidemia and anemia such as TC[(4.6±1.2)mmol、L vs(4.3±1.5)mmol、L],LDL-C[(2.8±0.8)mmol、L vs(2.7±0.8)mmol、L],and Hb[(110.6±22.5)g、L vs(105.5±31.7)g、L]were significant higher in TN group than those in Non-TN group(P <0.05). Conclusions The thyroid nodule is common in centenarian population and its prevalence was higher in female than male.The associations between TN and biomarkers of dyslipidemia and anemia are found in the present study.

Objective To explore the feasibility of establishing an acute pericardial effusion animal model guided by ultrasound. Methods Six experimental pigs were anesthetized. A PTC needle was injected and guided to the right ventricular anterior wall under real-time high frequency ultrasound,40 ml and 80 ml normal saline were respectively infused into the pericardial cavity within 5 minutes. Ultrasonography and pathologic examination were applied to confirm this porcine model. The amount of the fluid was estimated by ultrasound at 1 hour and 8 hours after infusion. Results With ultrasound guidance,the PTC needle smoothly entered the pericardial cavity and the saline was successfully injected. The fluid dispersed from local to the entire pericardial cavity. Pericardial effusion last within 8 hours and no significant change of the fluid amount was found (all P ＞0.05). This acute pericardial effusion model was successfully established with a rate of 100%. Conclusions It is feasible to establish an animal model of acute pericardial effusion under the guidance of ultrasound. This method is safe,rapid and effective. It can provide a suitable animal model for the study of acute pericardial effusion.

Objective:To analyze the clinical efficacy of the Yuying powder combined with the Huanglian Shangqing pill for the treatment of subacute thyroiditis (SAT) with cervical anterior pain as the main complaint, as well as its impact on serum pain factors and oxidative stress levels in patients.Methods:A prospective selection of 100 SAT patients with anterior cervical pain as the main complaint admitted to the Hebei Provincial Hospital of Traditional Chinese Medicine from January 2020 to May 2022 was conducted. They were randomly divided into two groups, with 50 patients in each group. The control group was treated with sustained-release diclofenac sodium tablets, while the observation group was treated with external application of the Yuying powder and internal administration of the Huanglian Shangqing pill. After 2 weeks of continuous treatment, the analgesic efficacy and adverse drug reactions of both groups were observed. The analgesic onset time of two groups of anterior cervical pain was compared. Two simplified McGill pain questionnaires before and after treatment [the SF-MPQ scores, including Pain Rating Index (PRI), Visual Analog Scale (VAS), and Current Pain Intensity (PPI) ], were compared; the traditional Chinese Medicine Syndrome Score, Serum Pain Factors levels [ tumor necrosis factor (TNF)- α, interleukin-1 β(IL-1β), prostaglandin E 2 (PGE 2), and nitric oxide (NO) ] and oxidative stress indicators [the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) ] were also compared. Results:The total effective rate of analgesia in the observation group [98.00%(49/50)] was significantly higher than that in the control group [82.00%(41/50)] ( P<0.05). The analgesic onset time in the observation group was significantly shorter than that in the control group ( P<0.05). After treatment, the scores of various components (PRI, VAS, PPI) and traditional Chinese medicine syndrome scores in the two groups of SF-MPQ were significantly reduced compared to before treatment (all P<0.05); and the decrease was more significant in the observation group (all P<0.05). After treatment, the serum levels of TNF -α, IL-1β, PGE 2, and NO in both groups significantly decreased compared to before treatment (all P<0.05), and the levels of serum pain inducing factors in the observation group were significantly lower than those in the control group (all P<0.05). After treatment, both groups showed a significant decrease in serum MDA content (all P<0.05), and a significant increase in serum SOD and GSH-Px levels (all P<0.05); And the improvement was more significant in the observation group (all P<0.05). The incidence of adverse reactions in the observation group [4.00%(2/50)] was lower than that in the control group [16.00%(8/50)] ( P<0.05). Conclusions:The overall efficacy of external application of Yuying powder combined with oral administration of Huanglian Shangqing pill in the treatment of SAT with cervical anterior pain as the main complaint is definite, and its effect may be related to significantly downregulating the expression level of serum related pain inducing factors in patients and reducing the level of oxidative stress in the body.

Objective:To explore the effects of phased goal directed fluid therapy (GDFT) during anesthesia surgery on tissue perfusion and cognitive function in patients undergoing radical lung cancer surgery.Methods:A total of 108 lung cancer patients were prospectively selected and randomly divided into a control group and a study group using a random number table method. The control group received classical restrictive liquid therapy, while the study group received staged GDFT. We compared the surgical time, intraoperative blood loss, colloid fluid dosage, crystalloid fluid dosage, total output, and urine volume between two groups of patients; Two groups of patients were compared in terms of oxygenation index (OI), respiratory index (RI), central venous oxygen saturation (ScvO 2), lactate (Lac), central venous arterial carbon dioxide partial pressure difference (Pcv-aCO 2), oxygen supply index (DO 2I), and oxygen uptake rate (O 2ERe) before anesthesia induction (T 0), before single lung ventilation (T 1), 1 hour of single lung ventilation (T 2), immediate resumption of dual lung ventilation (T 3), 30 minutes of dual lung ventilation (T 4), and after surgery (T 5); The Mini Mental State Examination (MMSE) was used to evaluate the cognitive function scores of two groups of patients 1 day before surgery and 1 and 3 days after surgery, while recording the incidence of cognitive dysfunction (POCD) and pulmonary complications (including pulmonary infection, acute lung injury, pulmonary embolism, pulmonary edema, atelectasis, etc.) within 3 days after surgery. Results:The amount of crystal fluid and urine output in the research group was significantly lower than that in the control group, while the amount of colloidal fluid was significantly higher than that in the control group (all P<0.05). The OI of the study group T 1-T 5 was significantly higher than that of the control group, while the RI of T 2-T 5 was significantly lower than that of the control group (all P<0.05). The ScvO 2 of the study group T 1 to T 5 was significantly higher than that of the control group, and the Lac was significantly lower than that of the control group (all P<0.05); The MMSE scores of both groups of patients were significantly lower than those before surgery on day 1 and 3 after surgery, and the MMSE scores of the study group were significantly higher than those of the control group on day 1 and 3 after surgery (all P<0.05). The incidence of POCD within 3 days after surgery in the study group was 16.67%(9/54), lower than 37.04%(20/54) in the control group (χ 2=5.704, P=0.017); The incidence of pulmonary complications in the study group was lower than that in the control group (5.56% vs 22.22%, χ 2=4.955, P=0.026). Conclusions:The application of staged GDFT during anesthesia in patients undergoing radical lung cancer surgery can further improve tissue perfusion, improve microcirculation and oxygen supply-demand balance of systemic organs and tissues, including the brain, alleviate perioperative brain function damage, and reduce the occurrence of postoperative POCD compared to conventional liquid therapy.

Objective: To study the correlation of lifestyle characteristics with thyroid nodules in a population-based sample of centenarians in Hainan. Methods: The study was based on China Hainan Centenarian Cohort Study (CHCCS) conducted in 18 cities and counties in Hainan province from 2014 to 2016. A group of multidisciplinary team interviewed and examined local centenarians with structured questionnaires and ultrasonography procedures. A total of 918 centenarians were analyzed after excluding those who refused ultrasonographic examinations or had relevant missing data. Thyroids of centenarians were examined by 3-year experienced sonographer, details on lifestyle characteristics and dietary habits were collected by standard procedure. Results: Of the 918 centenarians, 683 (74.4%) had thyroid nodules under the ultrasonography procedures. The prevalence of thyroid nodules in different group of areca nut consumption varied significantly (P<0.05). In multivariate logistic regression model, the results showed female and areca nut intake were independently associated with thyroid nodules in centenarians (P<0.05). Conclusions The modifiable variables including areca nut intake as well as non-modifiable such as gender are independent determinants of thyroid nodules in centenarians. Further studies are warranted to explore and verify these associations in populations with different ranges of age.

OBJECTIVETo study the techniques and efficacy of neuronavigation-guided puncture and drainage in the treatment of brain abscesses.

METHODSFrom February 2006 to December 2012, 31 patients with brain abscesses treated by the technique of neuronavigation-guided puncture and drainage were retrospectively analyzed. There were 27 male and 4 female patients, age ranged from 10 months to 69 years, average (34 ± 19) years.Single brain abscesses were found in 26 patients, multiple abscesses in 5 patients. The abscesses were located in eloquent regions in 19 patients. The mean diameter of the abscess was 4.1 cm (2.5-6.7 cm). The first follow-up visit was on the first month after surgery, and if residual was observed on enhanced MRI, then the patient was followed up every 3 months until the abscess disappeared completely. After residual absorbed, the patient was followed up every year.

RESULTSIncisions of all patients were healed well and no infection. The length of hospital stay after surgery was 6-42 days, mean (14 ± 9) days. Bacterial culture of pus was performed regularly including aerobic, anaerobic and fungal culture after surgery. Thirteen patients had positive culture whereas the other 18 patients had negative culture. The duration of antibiotic use was 18-42 days, mean (22 ± 5) days. All the patients were followed up for 3 months to 3 years. Twenty-nine patients recovered well postoperatively, 1 case died 2 months after operation.One case was performed the second drainage after 10 days from the first surgery.Eighteen patients showed the improvement of neurological status within the first day following surgery, 4 patients got improvement in the next day, 1 patient with hemiplegia showed improvement in 10 days postoperatively, 1 patient with aphasia recovered gradually after 1 month, 1 patient with hemiplegia showed deterioration temporarily after surgery, and recovered gradually after 15 days.

CONCLUSIONThe technique of puncture and drainage guided by neuronavigation has many advantages to treat brain abscesses, such as small trauma, short operation time, high accuracy and safety, simple surgical procedures and good prognosis.
