Objective To explore how to treat open neck trauma in time and with reason in the primary hospital.Methods 57 cases of neck open injury were hospitalized from Aug.1997 to Jan.2()07,and injury cause,mechanism,diagnosis and treatment of them are analyzed retrospectively.Results There were 29 incisal wounds and 23 penetrating wounds and 5 contusing wounds.Among 57 patients there were 12 significant injuries and 55 minor injuries cases.53 patients had been treated with operative exploration and 10 patients had therapeutic exploration.The result of treatment showed that 50 patients were cured,and 4 patients died of head injury,cervical spinal injury and respiratory failure,anoxic encephalopathy from airway obstruction and hemorrhagic shock from combined injuries of common carotid artery and internal jugular vein.Conclusion The mainstay of choice of treatment is the injury mechanism and clinical signs and symptoms of patient.

Objective To explore applied characteristics of the prolene hernia system(PHS) in inguinal hernioplasty, and management during and after operation, and long-term effect of this kind of hemioplasty in aged patients. Methods 69 aged patients using PHS were followed and analyzed retrospectively. Results Tension-free inguinal hernioplasty with the PHS were performed in 69 aged patients of groin hernia. Operative time ranged from 45min to 160min. Post-operatively, 3 patients developed gentle scrotal swelling, and 20 patients had been adminis- tered anodyne for pain of incision, and 12 cases experienced retention of urine, 1 case developed pneumonia, and 2 cases oeeurred incisional infection and gore. 68 cases of them recovered daily life about 2 to 3 weeks after operation. During follow-up period from 6 months to 77 months,there was no recurrence of inguinal hernia and no pain in in-guinal region, but 2 patients feel discomfort sporadically. Conclusion The PHS strengthens the myopectineal orifice and seals up-area of it,so the system is especially preferred in treating aged patients of groin hernias who have some defectsof anatomic structure in inguinal region. The local anaesthesia is also suitable for this kind of hernioplasty in aged patients.

Objective To evaluate the clinical curative effect of Salvia miltiorrhiza Ligustrazine combined with Butylphthalide in cerebral infarction of children. Methods Sixty-two children with acute cerebral infarction were randomly divided into treatment group (33 patients) and control group (29 patients). The patients in two groups received the same basic treatment. The control group used Salvia Ligustrazine injection, and the treatment group used Salvia Ligustrazine injection combined with Butylphthalide. The total efficiency, the degree of recovery of muscle strength and the scores of nerve defect 2 weeks after treatment were compared. Results The total efficiency in treatment group was 87.9%(29/33), in control group was 75.9%(22/29), and there was significant difference (P<0.05). Two weeks after treatment, the muscle strength scores in treatment group was (4.00 ± 0.47) scores , in control group was (3.59 ± 0.98) scores, and there was significant difference (P<0.05). Two weeks after treatment, the scores of nerve defect in treatment group was (5.42 ± 2.18) scores, in control group was (6.86 ± 2.23) scores, and there was significant difference (P<0.05). Conclusions Salvia Ligustrazine combined with Butylphthalide in treatment of cerebral infarction of children has obvious effect, and it is worthy of spreading.

AIM:To explore the changes of L-selectin expression and F-actin distribution of leukocytes from pancreatic circulation in the experimental acute necrotizing pancreatitis (ANP) rats and impact of Chinese herbs west China pancreatitis yi hao (WPY) on them in vivo. METHODS:Forty-four Wistar rats were randomized into control group,ANP group and ANP WPY treated group. The leukocytes from blood of splenic vein were incubated with PE-anti-CD62L for L-selectin and TRTIC-Phalloidin for F-actin,then the ratio of CD62L positive granulocytes was measured by flow cytometry and leukocytes were taken images with confocal laser scanning microscope. The distribution of F-actin at the border or central part of leukocyte was analyzed by using Mias system. RESULTS:The ratio of CD62L positive granulocytes increased in ANP rats,but those increases at 6 h (31.78%?12.37%) and 12 h (29.83%?13.73%) were significant [vs control group(11.96%?5.32%),P

Objective: To evaluate the occupational health risk of decorative coating manufacturing enterprises and to explore the applicability of occupational hazard risk index model in the health risk assessment, so as to provide basis for the health management of enterprises. Methods: A decorative coating manufacturing enterprise in Hebei Province was chosen as research object, following the types of occupational hazards and contact patterns, the occupational hazard risk index model was used to evaluate occupational health risk factors of occupational hazards in the key positions of the decorative coating manufacturing enterprise, and measured with workplace test results and occupational health examination. Results: The positions of oily painters, water-borne painters, filling workers and packers who contacted noise were moderate harm. And positions of color workers who contacted chromic acid salts, oily painters who contacted butyl acetate were mild harm. Other positions were harmless. The abnormal rate of contacting noise in physical examination results was 6.25%, and the abnormality was not checked by other risk factors. Conclusion The occupational hazard risk index model can be used in the occupational health risk assessment of decorative coating manufacturing enterprises, and noise was the key harzard among occupational harzards in this enterprise.

Objective:To study the clinical characteristics and treatment measures of postoperative bleeding in hyperparathyroidism surgery.Methods:A total of 56 patients with secondary hyperparathyroidism in Shunde Hospital from November 2014 to November 2018 were underwent parathyroidectomy, from which 5 cases developed postoperative hemorrhage were collected and analyzed.Results:Among the 56 patients, bleeding after operation were found in 5 cases(5/56, 8.93%), including hemorrhage of anterior jugular vein in 1 case, hemorrhage of thyroid wound after thyroid mass resection in 1 case, hemorrhage of anterior jugular muscles in 3 cases, hemorrhage of cricothyroid muscle in 1 case.All patients were cured by treatment in time without death.Conclusion:Early diagnosis and proper treatment are crucial for reducing the complications of post-parathyroidectomy bleeding.

‍ ObjectiveTo investigate the diagnostic efficacy and optimal cut-off values of alpha-fetoprotein （AFP） and alpha-fetoprotein variant L3 （AFP-L3） in hepatitis B virus （HBV）-related early-stage hepatocellular carcinoma （HCC）. MethodsA total of 1 080 patients with HBV-related HCC （HBV-HCC） who were diagnosed for the first time and not yet treated in The Third Affiliated Hospital of Sun Yat-Sen University from January 2019 to July 2022 were enrolled as HCC group in the study， among whom there were 620 patients with CNLC Ⅰ‍a-‍Ⅱ‍a HCC， and in addition， 346 patients with HBV-related chronic hepatitis B （CHB group） and 293 patients with HBV-related liver cirrhosis （LC group） were enrolled as controls. The diagnostic efficacy of AFP and AFP-L3% in screening for HBV-related early-stage HCC was analyzed， including sensitivity， specificity， and the area under the ROC curve （AUC）. The Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups； the Kruskal-Wallis H test was used for comparison between multiple groups， and the Bonferroni method was used for further comparison between two groups. ResultsThe HCC group had significantly higher levels of AFP and AFP-L3% than the CHB group and the LC group （H=542.479 and 418.974， both P<0.001）. In early-stage HCC， AFP and AFP-L3% had an optimal cut-off value of 8.7 ng/mL and 5%， respectively， and AFP alone had the largest AUC of 0.816， with a sensitivity of 66.9% and a specificity of 85.1%. There was no significant difference in AUC between AFP-L3%+AFP and AFP alone （Z=0.609， P=0.543）， but both AFP-L3%+AFP and AFP alone had a significantly larger AUC than AFP-L3% alone （AFP vs AFP-L3%： Z=8.173， P<0.001； AFP+AFP-L3% vs AFP-L3%： Z=8.802， P<0.001）. ConclusionAFP has a good value and is superior to AFP-L3% in the diagnosis of HBV-related early-stage HCC， and the screening cut-off value of AFP should be lowered in order to improve the detection rate of early-stage HCC.
