OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

OBJECTIVE: To observe the effect of sevoflurane on the induction and maintenance of anaesthesia in children, and to evaluate its safety and effectiveness. METHODS: Forty child patients who conformed to the selection standard were operated under anaesthesia with intubation.Without premedicant, all the patients inhaled 100% oxygen(1L/min) and sevoflurane by mask, and escalated the concentration of sevoflurane (to the maximum concentration 7%) until the lash reflex disappeared, and the maintenance concentration was controlled under 4%. All the patients were intubated, together with vecuronium 0.1mg/kg. RESULTS: With little tract excretion, the achievement ratio of induction by sevoflurane was 100%, and the children tolerated well. With stable hemodynajmics,1% approximately 4.0% maintenance concentration of sevoflurane during the operation showed effective anaesthesia, no decreased heart rate or blood pressure appeared, and all the patients' body temperature was normal. CONCLUSION Sevoflurane for children induction can bring fewer stimuli in the respiratory tract,less cardiac vascular inhibition and palinesthesia time. Anaesthesia in children induced by sevoflurane is safe and effective.

AIM To investigate the effect of Shenfu Injection on atherosclerosis (AS) models of high-fat apolipoprotein E-deficient (ApoE-/-) mice,and to explore its anti-atherosclerosis mechanism through the observation of oxidative stress (OS) variation.METHODS C57 mice were used as controls.ApoE-/-mice fed with 20-week high fat diet were randomly divided into model group,Shenfu group for subsequent 4-week continuous corresponding intervention,after which the mice had their blood lipid levels measured,their levels of MPO and NOX4 identified by ELISA,and their T-SOD activity determined by hydroxylamine method,their MDA level detected by TBA,their plaque formation observation achieved by HE staining of aortic gross and red O of all the aorta,and their Nrf2 mRNA expression detected by real time qPCR method.RESULTS Compared with the control group,the model group manifested with increased contents of TG,TC,LDL,decreased HLD;decreased activity of SOD,increased contents of MPO,NOX4 and MDA,and down-regulated expression of aortic Nrf2 and Keap1 mRNA.Compared with the model group,Shenfu Injection group was observed with no obvious blood lipid level change,but a reduction of plaque area,and an effective inhibition on OS as revealed by improved levels of Nrf2 and Keap1 mRNA.CONCLUSION Shenfu Injection can activate Nrf2 and interfer the relevant enzymes,thus prevents the atherosclerosis progression through OS reduction.

OBJECTIVETo investigate the correlations between electrogastrogram (EGG) and gastric emptying (GE) in children with functional dyspepsia (FD).

METHODSA total of 51 children with FD and 25 healthy children as control were enrolled into this study. Polygraph ID 4-channel EGG analysis system was used for EGG recording and gastric emptying of solids was studied by using a standardized egg meal labeled with (99m)Technetium sulfur colloid for each subject.

RESULTS(1) Compared with the control group, the percentage of normal slow wave (N%) in the FD group was significantly lower than that of the control group (P < 0.01). Children with FD had higher rates of abnormal EGG, in which 32 cases showed mixed dysrhythmia preprandial and postprandial recordings (62.7%). (2) The two groups had significant difference in ratio of the percentage of preprandial dominant power (DP) to postprandial DP (P < 0.05), it showed that the postprandial DP of the FD group did not increase. (3) The postprandial dominant power instability coefficient (DPIC) as well as preprandial DPIC and dominant frequency instability coefficient (DFIC) in the FD group were increased. The coupling of the slow wave of preprandial and postprandial EGG in the FD group (26.95 +/- 13.69, 26.93 +/- 12.63 respectively) significantly decreased as compared with those in the control group (69.02 +/- 5.15, 70.18 +/- 4.68, P < 0.01). (4) The rate of delayed gastric emptying in the FD group was 23.5%. The results of multivariate Logistic regression analysis showed that there was a significant negative correlation between the delayed gastric emptying and the coupling of the slow wave (partial regression coefficient = -0.513, -0.296 respectively).

CONCLUSIONSPatients with FD had more abnormal findings in EGG than the control group did, and there was a significant negative correlation between the delayed gastric emptying and the coupled response of the slow wave. The abnormal gastric electrical activity may have certain significance in pathogenesis of FD.

OBJECTIVETo investigate the expression of phosphoglycerate kinase 1 (PGK1) and its prognostic value in endometrial carcinoma (EC).

METHODSThe expression of PGK1 was detected immunohistochemically in 30 normal endometrium and 130 EC specimens. The relationship between PGK1 protein expression and the clinicopathological features of the patients was evaluated.

RESULTSImmunohistochemical analysis revealed low PGK1 expression in 55.4% (72/130) and high PGK1 expression in 44.6% (58/130) of the EC specimens, as compared with the rates of 90% (27/30) and 10% (3/30) in normal endometrium, respectively (P<0.001). PGK1 expression was significantly correlated with FIGO stage (P<0.001), histological grade (P=0.002) and lymph node metastasis (P<0.001). Kaplan-Meier survival analysis indicated that patients with a high PGK1 expression had a shorter overall survival rate than those with a low PGK1 expression (P<0.001). Multivariate analysis showed that a high PGK1 expression was not the independent predictor of the prognosis of EC (P=0.077).

CONCLUSIONA high expression of PGK1 is associated with aggressive and metastatic behaviors of EC, and detection of PGK1 provides assistance in evaluating the prognosis of patients with EC.

OBJECTIVETo investigate the time course of calpain activity changes in rat neurons following fluid percussion injury (FPI) under normothermia (37 degrees celsius;) and mild hypothermia (32-/+0.5) degrees celsius;.

METHODSIn vitro cultured rat neurons were subjected to FPI followed by application of mild hypothermia for intervention at different time points, and the changes in intraneuronal calpain activity following FPI and the interventional effect of mild hypothermia on calpain activity were evaluated by UV-spectrophotometry at different time points.

RESULTSRemarkable changes occurred in calpain activity in the neurons following FPI at 37 degrees celsius;, and mild hypothermia produced obvious interventional effect on calpain activity in close relation to the timing of intervention initiation.

CONCLUSIONIntraneuronal calpain activity changes following FPI are involved in the pathological process of cellular injury, and mild hypothermia might offer protection against traumatic brain injury to some extent by regulating calpain activity. The interventional effect of mild hypothermia is associated with the timing of the intervention initiation.

OBJECTIVETo evaluate the stability of hearing results and complications in long-term following-up who underwent reconstruction surgery.

METHODSSix hundreds and seventy five cases (700 ears) of congenital aural atresia were reviewed from January 1984 to January 2001 at the Department of Otorhinolaryngology Head and Neck Surgery, Tongren hospital. Except 40 ears undone hearing reconstruction, 635 cases (660 ears) underwent long-term following-up for 3 to 19 years, with an average of 7.9 years.

RESULTSStenosis and recurrent infection of the external auditory canal (EAC) were the most frequent complications. Stenosis was seen in 120 ears, and 2 ears re-atresia, with an incidence of 18.48% (122/660). Recurrent infection of the cavity and canal skin happened in 6 ears. Closure of the air-bone gap (ABG) post-operation were gained in all cases, and ABG gains 20 dB or more occurred in 512 ears (77.57%), but 30 dB or more in 231 ears (35%). Following-up results: Stable hearing results gained in 450 ears over the length of following-up; the hearing worsened than that of 3 weeks postoperatively occurred in 160 ears, including 2 ears with sensorineural hearing loss. Hearing deteriorated more than 20 dB happened in 35 ears, and 10-15 dB in others cases but still be improved compared with that of preoperation.

CONCLUSIONSAtresiaplasty surgery in individuals with congenital aural atresia can yield reliable, lasting hearing results in 68.2% (450/660), with a low incidence of complications; the initial improved hearing deteriorated gradually over the first 6 months post-operation, which are related with the stenosis and infection of canal. Cavity adhesion, bony EAC re-growth, ossicular chain re-fixation or displace may affect the hearing results in some cases. Even unilateral aural atresia may benefit from the reconstruction surgery and achieve serviceable hearing results.

OBJECTIVETo survey the sleep habits (bedtime, wake time), sleep duration, and sleep problems in school-age children of China.

METHODFrom November to December, 2005, a total of 19,299 school-age children from 55 elementary schools of 9 cities entered the study by a cross-sectional survey. A parent-administered questionnaire and the Chinese version of the Children's Sleep Habits Questionnaire were applied to investigate children's sociodemographic characteristics and sleep behaviors, respectively.

RESULTSThe mean sleep duration was 9 hours and 10 minutes (9:10, SD:48 min) during the weekdays and 9:48 (SD: 63 min) during the weekends. In about 71.4% and 41.8% school-aged children the sleep duration per day did not reach the lowest criterion of 10 hours recommended by the Ministry of Education of China during weekdays and weekends, respectively. Sleep problems were common with prevalence ranging from 14.5% for sleep-disordered breathing to 75.3% for daytime sleepiness. Parasomnia (chi(2) = 13.76, P < 0.01) and sleep-disordered breathing (chi(2) = 119.83, P < 0.01) were more prevalent in boys than in girls; however, sleep anxiety was more prevalent in girls than in boys (chi(2) = 19.42, P < 0.01). Except for night waking, other types of sleep problems were significantly associated with age.

CONCLUSIONSInadequate sleep duration and sleep problems prevail among school-age children, which indicates that children's sleep health may be a major public health concern in China.

Objective To develop a diagnostic model based on deep neural network for intelligent discrimination of thyroid function. Methods A total of 1616 patients ( 283 males, 1333 females, average age:52 years) who underwent thyroid imaging between May 2016 and June 2018 were selected. According to the clinical diagnosis, the 1616 cases included 299 normal thyroid cases, 876 hyperthyroidism cases and 441 hypothyroidism cases. Feature extraction and learning training were performed on 1000 training set sam-ples by two deep neural network models ( AlexNet;deep convolution generative adversarial networks ( DCGAN) ) using deep learning algorithm. Performance verifications were implemented on 616 test set samples. The con-sistency between the verification results of the two models and the clinical diagnosis was analyzed by Kappa test. Meanwhile, the time advantage of the intelligent diagnosis models was analyzed. Results The average diagnostic time of AlexNet model was 1 s/case, and the classification accuracy for normal thyroid, hyperthy-roidism, hypothyroidism were 82.29％(79/96), 94.62％(369/390), 100％(130/130), respectively. The Kappa value between results of AlexNet model and clinical diagnosis was 0.886 ( P<0.05) . The average di-agnostic time of DCGAN model was 1 s/case, and the classification accuracy for normal thyroid, hyperthy-roidism, hypothyroidism were 85.42％(82/96), 95.64％(373/390), 99.23％(129/130), respectively. The Kappa value between results of DCGAN model and clinical diagnosis was 0.904 ( P<0.05) . Conclusion The deep neural network intelligent diagnosis model can quickly determine the functional status of thyroid gland in thyroid imaging, and it has a high recognition accuracy, thus providing a new method for thyroid image review.
