Objective To explore the risk factors of recurrent cerebral infarction and the preventive meas-ures. Methods The risk factors were compared between recurrent group (246 cases with recurrent cerebral infarc-tion) and unrecurrent group( 100 cases with unreeurront cerebral infarction) by means of multiple logistic regression analysis. Results The recurrent cerebral infarction is correlated closely with hypertension, diabetes, heart diseases and excessive drinking, and the OR values arc 2.206, 2.232, 2.252, 2.842, 2.366 respectively (P<0.05), prophy-lactic treatment had the protective effects against the recurrent cerebral infarction,and the OR value was 0.249. Con-dusions The main risk factors of recurrent cerebral infarction were hypertension,heart diseases,excessive drinking. Prophylactic treatment hed great significance in preventing the recurrence of cerebral infarction.

Objective To investigate the influence of nebulized Pulmieort respules inhalation after endoscopic sinus surgery (ESS)on the expression of epithelial Na~+ channel(ENaC)protein in nasal mucosa. Methods Forty-four patients with nasal polyps undergoing ESS were randomly divided into Pulmieort respules treatment group(n=21,nebulized Pulmieort respules inhalation for 10 d after ESS)and Rhinocort control group(n=23,Rhinoeort aqueous nasal spray for 10 d after ESS).All the patients were performed biopsy of membrane on the residual middle turbinate 14 d after ESS,eosinophils (Eos)and neutrophils(Neu)per hundred inflammation cells were counted under microscope during ESS and after ESS,and the expression of ENaC protein was detected by immunofluorescence assay. Results The percentages of Eos and Neu decreased in two groups after treatment,and the percentage of Neu in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.05).The expression of ENaC protein after treatment in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.01). Conclusion Application of pulmieort respules after ESS can decrease Neu infiltration and inhibit expression of ENaC protein,which can relieve acute inflammation and edema of nasal mucosa.

Objective:To evaluate the role of Tg in diagnosis of lateral cervical lymph node recurrence in papillary thyoid cancer(PTC)after radioactive iodine(RAI) therapy.Methods:From Jan 2012 to Aug 2018, 22 PTC patients who received RAI therapy after operation were reoperated for lateral cervical lymph node recurrence. The clinical data was retrospectively analyzed.Results:The median recurrence time was 30.5 (5-86) months. All 22 patients received RAI therapy after the first operation, and the median dose of RAI was 250mCi(100-700 mCi) and the episode of RAI therapy ranged from 1 to 4. All 22 PTC patients underwent neck reoperation, among which 20 cases were identified to have lymph node metastasis. The median number of lymph nodes dissected was 31 (8-83) and median number of metastatic lymph nodes was 4 (1-19) . The diagnostic accuracy of ultrasonography in detecting lymph node metastasis was 90.9%. Before reoperation, the median Tg was 1.305 (0.10-99.51) μg/L, with the cutoff value of Tg being 0.2 μg/L, and its sensitivity and specificity were 80.0% and 100%, respectively. The median stimulated Tg was 5.89 (0.14-255.80) μg/L in the 10 patients, with the cutoff value of stimulated Tg of 2 μg/L, and its sensitivity and specificity were 88.9% and 100%, respectively.Conclusions:The serum Tg level is helpful for monitoring the recurence of PTC, but recurrence cannot be completely ruled out for those with low Tg.

OBJECTIVEThis study aimed to explore the differences of membrane thickness and pressure on the paranasal sinus membrane in goats and analyze their causes. The results can provide theoretical basis and guidance for the issues of the maxillary sinus floor augmentation related to the membrane.

METHODSThe membrane was cut into two sizes from every sinus membrane. The membrane was fixed in formalin to obtain tissue specimens for the membrane thickness study and pressure study. The correlation between the two parameters was then analyzed, and appropriate statistical methods and software were selected.

RESULTSThe top of maxillary sinus, the bottom of maxillary sinus and the frontal sinus membrane thickness were (410.03 ± 65.97), (461.33 ± 91.37), (216.90 ± 46.47) µm. The pressure were (260.08 ± 80.12), (306.90 ± 94.37), (121.72 ± 31.72) kPa. The mean differences of the membrane thickness between the top of the maxillary sinus and the frontal sinus, bottom and frontal, and top and bottom were statistically significant (P < 0.05). The mean differences in membrane pressure were also statistically significant (P < 0.05).

CONCLUSIONThe membrane thickness and pressure of the top and bottom of the maxillary sinus are higher than those of the frontal sinus membrane. However, the thickness and pressure of the bottom membrane are slightly higher than those of the top membrane. Pressure and membrane thickness are positively correlated in the sinus membrane.

Objective To investigate the effect of Neostigmine on Mivacurium Chloride in postoperative recovery of elderly patients with anesthesia.Methods A total of 46 patients (32 males,14 females,aged 60-73 years,ASA grade Ⅰ or Ⅱ) who underwent laparoscopic surgery for gastrointestinal tumor under general anesthesia,were randomly divided into two groups.Patients in the studying group (group A,n=22) were given a dosage of eostigmine 20 ug/kg after the end of surgery,and patients in control group (group B,n=24) were given 0.9% saline solution.Monitored the contract reaction of adductor pollicis through train-of-four ratio (TOFR) by stimulating ulnar nerve.Record condition of recovery from neuromuscular blocked,untoward effect after operation,the activity of the plasmacholinesterase at the time of induction of anaesthesia and extubation.Results The sex,age,height,weight,BMI,operation time,fluid volume,temperature,the activity of the plasmacholinesterase,recovery score and sedation score had no significant difference.Activity decline of the plasmacholinesterase is obviously related with infusion liquid volume,was statistically significant(P<0.05),group A is lower than group B obviously at the recovery of TOFR to 25%,to 70%,70% to 90%,onset time and recovery index time,was statistically significant (P<0.05),the difference of TOFR of the two groups was statistically significant at the time of 5 min、10 min、30 min after extubation (P<0.05).The difference of the incidence of TOFR<0.7 of the two groups at the time of 5 min,10 min,30 min after extubation and the difference of the incidence of TOFR<0.9 of the two groups at the time of 10 min,30 min after extubation were statistically significant (P<0.05).Conclusion There is obvious significance for neostigmine to resume muscle force in mivacurium chloride postoperative recovery in the elderly.

Objective To investigate the feasibility and effectiveness of fast track surgery (FTS) in neurosurgery. Methods One hundred fifteen patients who underwent neurosurgery surgery in Henan Province People's Hospital from June 2012 to March 2014 were enrolled in this study. All the patients were divided into FTS group (62 cases) and the tra?ditional operation group (53 cases). The clinical index, postoperative hospital stay and hospitalization cost were compared between the two groups. Results The clinical index were significantly lower in FTS group than in traditional operation group (P<0.05). Length of hospital stay (days) and hospitalization cost of FTS group were significantly shorter and lower in FTS group compared with traditonal operation group (8±1 vs. 11±2 days and RMB 4.58 ±0.75 vs. 5.78 ±0.64 ten thou?sand, respectively) (P<0.05). Conclusion FTS in neurosurgery operation is an all-new concept for surgery which can ef?fectively reduce postoperative complications, shorten length of hospital stay, decrease hospitalization cost and promote postoperative recovery.

Objective:To investigate the recurrence of the neck and survival incidence of clinically possible pos-itive lateral cervical nodes in patients with well-differentiated papillary thyroid cancer and the essentiality of the performation of modified radical neck dissection. Method: Retrospective datum of 267 cases of papillary thyroid car-cinoma were collected and ananlyzed. They were divided into two groups with time; selective neck dissection with VI area was performed in 151 cases of group A and selective neck dissection was performed without VI area in 116 cased of group B. They were received the same treatment in the thyroid-total thyroidectomy on initial part and subtotal thyrodectomy on the other, and total thyroidectomy on both parts if both were invated. Incidence of posi-tive lateral cerivcal nodes of VI area in group A and the recurrence in the neck and survival incidence in groups B were analyzed. Result: Fiftynine patients in group A were treated with the modified radical neck dissection, and 22 patients of them were found metastasis in lateral cervical nodes with Ⅵ area. The other 92 patients were treated with neck dissection of Ⅱ,Ⅲ,Ⅳ,Ⅵ VI area, and 31 patients weren't metastasis, 33 patients were metastasis in both Ⅵ area and the others(35.8%), 17 patients were metastasis only in Ⅵ area(18.4%), 11 patients weren't metastasis only in Ⅵ area(11.9%). Thus, the incident of metastasis in Ⅵ area was 47.70% in group A(72/151). 47 patients in group B had metastasis in lateral cervical nodes though without performing VI area neck dissection (40.5%), and the survival rate of 5 years was 99.3%. The recurrence rate in the neck of group two was 6.0% (7/116). The metastasis rate of neck lymph node was higher in group A (54.9%) than group B(40.5%). Conclu-sion : Pretracheal and peripheral recurrent nerve lymph node are very susceptible to the metastasis of well-differenti-ated papillary thyroid cancer. The neck dissection of VI area could be performed as routine.

Objective To study the relationship between portal hypertension(PHT) and heme oxygenase-1(HO-1)mRNA expression in rats.Method An animal model of PHT induced by partial portal vein constriction was established to detect the expression of HO-1mRNA in the liver,spleen, and splenic vein of rats by situ hybridization method. Result HO-1mRNA was not detected in the liver, spleen, and splenic vein in the control group. In PHT rats, HO-1mRNA was not detected in the liver;but in the spleen,the expression of HO-1mRNA was 83.3%;in the splenic vein,the expression was 55.6%. Conclusions The PHT rat is in stress condition.The expression of HO-1mRNA in the spleen and splenic vein of PHT ratsare increased and the metabolic product of HO-1 may exacerbate the PHT.

Objective To discuss The Clinical Significance of Eosinophil (EOS) in urosepsis. Methods A total of 99 patients of urosepsis in Department of Urology,Guangdong Provincial TCM Hospital from Mar. 2013 to Jul. 2016 were selected as research objects by retrospective analysis. The patients were classified into groupEOS= 0 andgroup EOS > 0,group PCT(procalcitonin)≥ 2 ng/mL andgroup PCT < 2 ng/mL,the differences of PCT concentration and percentage of EOS in two groups were analyzed comparatively. 99 patients of urosepsiswere also compared the difference of the percentage of EOS with another group including 100 patients of urinary tract infection (UTI) without Sepsis. Results The percentage of EOS was significantly decreased in 86.9%(86/99)of patients of urosepsis. The paired student t test show the percentage of EOS in two days after treatment,four days after treatment, before hospital discharge were higher than that before the treatment, the difference wassignificant (P < 0.05). The Independent-Sample Test show that the PCTconcentration in EOS = 0 group were higher than EOS > 0 group,the percentage of EOS in PCT≥2 ng/mL groupwere lower than PCT<2 ng/mL group,difference were significant(P<0.05). And The Independent-Sample Testalso showed that the percentage of EOS of the Urosepsis group was definitely lower than the UTI group without Sepsis. Difference was statistically significant. Concusions The percentage of EOS could be applied to assess the severity of urosepsis, monitor the disease progression and evaluate the infection control. The cost was lower than PCT in therapeuticprocess ofurosepsis.
