Objective To explore the effect of gene mutations of epidermal growth factor receptor ( EGFR) on targeting therapy of advanced non-small cell lung cancer (NSCLC). Methods The 139 hospitalized patients who had been treated at least once with platinum-based chemotherapy and had tumor progression or recurrence after the last chemotherapy between December 2005 and December 2009, underwent EGFR gene test extracted from the pathological tissues. Based on the results of the test, the patients were divided into three groups: EGFR mutation per os (p.o.)Gefitinib (MPG) group, wild-type EGFR per os (p. o. ) Gefitinib (WpG) group and wild-type EGFR post-docetaxel chemotherapy (WpD) group. Clinical characteristics, pathology, treatment efficacy,survival time, performance status (PS) score, adverse reaction and quality of life of patients in the three groups were assessed. Results The EGFR mutation rate were higher in female, patients with adenocarcinoma and non-smokers than in male, smokers and those without adenocarcinoma. There were significant differences in median progression-free survival and median survival time among the three groups, which were 2.8 and 8. 9 months in MpG group, 2.0 and 7.1 months in WpG group,2.5 and 7. 8 months in WpD group(H=11. 198, 16. 991 ,all P＜0.01). The changes of PS score were significantly different between MpG group and WpG group (96. 8% vs. 62. 0%, x2 = 12. 583 ,P＜0. 01 ). However, there was no difference in changes of PS score between WpG group and WpD group (62. 0% vs. 66. 0%, x2 =0. 878,P＞0. 05). Conclusions The gene mutation of epidermal growth factor receptor may be served as an important indicator of advanced non-small cell cancer therapy.

Objective To observe the effects of electro-acupuncture (EA) on body weight, insulin resistance, hypothalamic agouti gene-related protein (AGRP) and neuropeptide Y (NPY) in diet induced obesity (DIO) rats; To discuss its mechanism for DIO.Methods Fifty SD male rats were randomly divided into low fat diet groups (LFD) and high fat diet group. After the DIO models were established, the successful model rats were randomly divided into model group, EA group and Orlistat (OLST) group. EA was applied to “Zusanli” (ST36) and “Quchi” (LI11) for 20 minutes. The treatment was done once a day for 28 days. OLST was treated with orlistat by gavage. LFD and model did not receive treatment. Body weight was recorded every day. FPG and FINS were detected. The expressions of AGRP and NPY were detected by RT-QPCR. Morphological changes of adipocyte and liver were examined by HE staining.Results The body weight, HOMA-IR, AGRP, NPY and diameter of adipocyte of EA group and OLST group were significantly lower than model group (P<0.05), difference between EA group and OLST group. The states of hepatic steatosis were improved in EA group and OLST group.Conclusion EA has the effects on weight loss by inhibiting the expressions of AGRP and NPY by improving IR.

Vigabatrin-associated brain abnormalities on magnetic resonance imaging (VABAM) is a relatively rare side effect of vigabatrin, most of which are asymptomatic. However, there will be extremely rare cases with hyperkinetic disorders, myoclonus, tremor, and acute encephalopathy under certain circumstances. VABAM is often underappreciated by physicians and its accurate incidence remains unclear. A female infant who was diagnosed with infantile spasms and required adrenocorticotropic hormone therapy accompanied by various antiseizure medicines was reported. Unfortunately, she became lethargic and her spasm deteriorated gradually after vigabatrin exposure. Her brain magnetic resonance imaging revealed abnormal signals bilaterally in the dorsal midbrain, thalamus, and rostral part of the pallidum. She had a seizure amelioration and became lively as a result of vigabatrin withdrawal. In the meanwhile, magnetic resonance imaging returned to normal. Attempts were made to discover the risk factors of VABAM and potential pathogenesis. Further understanding of the disease should contribute to decreasing misdiagnosis and making precise decisions.

Objective To assess the schistosomiasis transmission risk after flood disaster in Hubei Province in 2021, so as to provide a scientific basis for schistosomiasis prevention and control in corresponding areas. Methods The data pertaining to the endemic situation of schistosomiasis were collected from Hubei, including oncomelania snail distribution, and humans and livestock schistosomiasis infection. The warning water level and actual water situation were collected in corresponding water areas. The cumulative numbers of S. japonicum egg-positive people and cattle from 2014 to 2020, the distribution area of oncomelania snail in 2020, and the water levels from May 1 to August 31, 2021, were estimated and employed as parameters for classification of schistosomiasis transmission risk. The cumulative value of each risk index was calculated in each epidemic county (city and district) to comprehensively assess the risk of schistosomiasis transmission after flood disaster in each region. Results After the flood disaster in Hubei province in 2021, there were 2 counties (districts) at high risk of schistosomiasis transmission in Hubei based on the single risk index of fecal positive number. Based on comprehensive risk indices, there were 2 counties identified at grade 4 risk of schistosomiasis transmission. Conclusion After the flood in 2021, schistosomiasis in Hubei Province is mainly at low and medium epidemic risk. Xiantao City and Hanchuan City in Hanjiang River Basin are the two most seriously affected schistosomiasis epidemic cities. Flood disasters can increase the risk of schistosomiasis transmission and epidemic, so the monitoring and control of schistosomiasis after flood should be strengthened to control the disease transmission to the maximum extent.

Newborn hearing screening is an effective method for early detection of hearing loss, however, it is not able to detect delayed-onset hearing loss. By exploring the etiology of delayed-onset hearing loss in children, it can provide a clinical basis for early detection of delayed-onset hearing loss. Mutations in SLC26A4, mitochondrial, GJB2 and other genes, enlarged vestibular aqueduct, congenital cytomegalovirus infection, extracorporeal membrane oxygenation, and auditory neuropathy et al were more commonly reported risk factors. In this paper, the risk factors related to delayed-onset hearing loss, which are divided into 5 categories: genetic mutation, abnormal inner ear malformation, perinatal factors, auditory neuropathy and no identifiable cause, are reviewed and analyzed.

Background Diurnal temperature range (DTR) is closely associated with cardiovascular health in the elderly, but there is a lack of research on the relationship between DTR and ischemic heart disease (IHD) in the elderly. Objective To investigate the effect of DTR on daily hospital admissions for IHD in people 65 years and older in Wuhan. Methods The study obtained data on elderly inpatients with IHD from all secondary and tertiary hospitals in Wuhan between January 1, 2017 and December 31, 2018, along with synchronous meteorological and air pollution data. Daily DTR was calculated as the difference between the maximum and minimum temperatures in a day. We employed distributed lag nonlinear models based on quasi-Poisson distribution to analyze the association between DTR and hospitalization risk in individuals aged 60 years and above. We assessed the extreme effects of DTR by selected DTR percentiles (the 1st percentile, P₁: 1.8 ℃; the 5th percentile, P₅: 2.9 ℃; the 95th percentile, P₉₅: 14.3 ℃; and the 99th percentile, P₉₉: 16.2 ℃) on hospitalization for IHD in the elderly population. Additionally, we conducted stratified analyses by gender, age (60-74 years and ≥75 years) and different subtypes (acute IHD and chronic IHD) to investigate the effects of DTR on hospitalizations for IHD across different genders, ages, and subtypes. Results This study included a total of 64212 first-time IHD hospitalizations among individuals aged 65 years and above in Wuhan from 2017 to 2018. The results showed a "J"-shaped exposure-response relationship between DTR and the cumulative risk of IHD hospitalization with a lag of 7 d; the optimal DTR was 5.0 ℃, and as DTR increased or the lag time lengthened, the risk of hospitalization for IHD in the elderly population increased. Extremely high DTR (P₉₉: 16.2 ℃) had a significant impact on the day of exposure (lag 0), with a cumulative RR of 1.58 (95%CI: 1.25, 1.99) at a lag of 7 d. The overall effects of DTR on IHD for different genders, ages, and subtypes of IHD exhibited similar patterns to the effects for overall population. High DTR had a significantly higher impact on hospitalization for chronic IHD (RR=1.46, 95%CI: 1.20, 1.79), compared to acute IHD (RR=1.29, 95%CI: 1.04, 1.61). At a cumulative lag of 7 d, elderly individuals aged 60-74 (RR=1.78, 95% CI: 1.30, 2.42) were more affected by high DTR in terms of IHD hospitalizations compared to those aged ≥75 (RR=1.35, 95% CI: 1.08, 1.70). Conclusion High DTR significantly increases the risk of hospitalization for IHD among elderly individuals. The effect of high DTR is particularly pronounced in patients with chronic IHD and elderly individuals aged 60–74 years.
