The epidermal growth factor receptor(EGFR)is a key oncogenic driver in non-small cell lung cancer(NSCLC),and its mutations have significant clinical implications.While classical mutations,such as exon 19 deletions and exon 21 L858R substitutions,are well estab-lished,increasing attention has shifted toward less common,non-classical EGFR mutation subtypes.The widespread adoption of high-throughput sequencing technologies such as next-generation sequencing(NGS)has substantially improved the detection rate of non-classic-al EGFR mutations.Thus,their molecular characteristics and therapeutic responses have been increasingly elucidated.However,due to their significant heterogeneity,substantial variability exists in the sensitivity of different non-classical mutations to EGFR tyrosine kinase inhibitors(EGFR-TKIs).Furthermore,the scarcity of clinical samples limits the availability of robust evidence.Additionally,prolonged clinical use of EGFR-TKIs can also lead to acquired resistance,further complicating treatment strategies.Despite these challenges,ongoing research continues to explore targeted therapies for patients with non-classical EGFR mutations.This review summarizes recent studies on non-classical EGFR mutations in NSCLC,examines current therapeutic approaches,and outlines clinical recommendations for managing patients after EGFR-TKI treatment failure.By integrating existing evidence and clinical experience,this review aims to optimize individualized treatment strategies for these patients,with the ultimate goal of improving their prognosis and quality of life.

Trigeminal neuralgia is characterized by intense pain in the sensory distribution area of the trigeminal nerve. It can be triggered by non-noxious stimuli such as brushing teeth and washing face. At present, the treatment of trigeminal neuralgia mainly includes oral drugs and surgical treatments. A 92-year-old patient with trigeminal neuralgia was reported. The pain could not be alleviated because the patient was unable to tolerate the side effects of drugs and surgical treatment. Taking into account the onset time and the duration of the curative effect, botulinum toxin type A was combined with cobrotoxin for the treatment of the patient. As a result, the pain symptoms were rapidly alleviated and remained in a relieved state for 8 months. The clinical characteristics of this patient were summarized in this article, and the possible synergistic mechanisms of action of the 2 drugs were discussed. The ultimate objective is to furnish a broader spectrum of alternatives and references for clinical practice.

Objective: To investigate the effects of lactoprotein iron chelates on rats with iron deficiency anaemia (IDA), so as to provide insights into developing and utilizing novel iron supplements. Methods: Seventy weaning female SPF-graded rats of the SD strain were randomly divided into the control group (A), model group (B), ferrous sulfate group (C), lactoferrin group (D), lactoferrin iron chelate group (E), Casein oligopeptide iron chelate group (F) and whey protein oligopeptide iron chelate group (G), with 10 rats in each group. The rats in group A were fed with normal diet, and the others were fed with poor iron diet for IDA modeling. The corresponding interventions were given by intragastric administration once a day. The iron ion concentrations of group C, E, F and G were 2.0 mg/kg, and the protein and oligopeptide concentrations of group D, E, F and G were 2 000 mg/kg. Body weight and hemoglobin of rats were measured weekly during 21-day intervention. At the end, peripheral blood samples were collected, and blood routine, iron metabolism and liver function indicators were determined. Results: After the intervention, among blood routine indicators, the rats in group C, E, F and G showed elevated hemoglobin, red blood cell, mean corpuscular volume and hematocrit, and decreased free protoporphyrin and mean corpuscular hemoglobin concentration when compared with the rats in group B (all P<0.05); among iron metabolism indicators, the rats in group C, E and G showed elevated serum ferritin, the rats in group C, E, F and G showed elevated serum iron, the rats in group C, D, E, F and G showed decreased unsaturated iron binding capacity and total iron binding capacity when compared with the rats in group B (all P<0.05); among liver function indicators, the rats in group E and G showed decreased alanine transaminase when compared with the rats in group B (both P<0.05). Conclusions Lactoprotein alone could not completely improve IDA in rats compared with traditional iron supplement (ferrous sulfate). Lactoprotein iron chelate, especially whey protein oligopeptide iron chelate, could significantly improve IDA, iron reserve and liver function damage in rats.

Objective To investigate the efficacy of dexmedetomidine on sedation in post-cardiac surgery patients with NIV intolerance.The changes of respiratory function and hemodynamics of the patients as well as non-invasive ventilation (NIV) failure rate were also under evaluation.Methods Thirty-five post-cardiac surgery patients with NIV intolerance and hypoxemia were enrolled in this prospective study.All patients were sedated with dexmedetomidine.NIV was standardized according to the uniform protocol.The main outcome was NIV success (avoiding endotracheal intubation) or NIV failure (requiring endotracheal intubation or die).The cardiorespiratory parameters (BP,HtR and RR) and artery blood gas analysis were prospectively recorded before and after sedation.The respiratory function and hemodynamics changes in both groups (NIV success group and NIV failure group) were then evaluated.Factors independently associated with NIV failure were identified using a logistic regression model.Results Twenty out of 35 patients (57.14％) survived while 15 (42.86％) patients failed NIV.After 1 h and 4 h of NIV with dexmedetomidine sedation,respiratory rate in both groups were decreased compared with baseline,especially in NIV success group.The PaO2/FiO2 was also improved after 1h and 4h of NIV treatment compared with baseline.The improvement was more significantly in NIV success group.The heart rate was decreased compared with baseline with no differences between two groups.There were no significant changes on PaCO2 and mean arterial pressure (MAP) during the treatment.The respiratory and hemodynamics variables identified as predictors of NIV failure were included in a multivariate logistic regression.RR ＞ 23 time/min (OR =3.2,95％ CI:2.043 ～ 4.301,P ＜ 0.01) 1 h after NIV,RR ＞ 20 time/min (OR =2.1,95％ CI:1.659～3.231,P=0.025) 4 h after NIV,PaO2/FiO2 ＜178 mmHg (OR=2.4,95％CI:1.892 ～ 3.287,P ＜0.01) 1 h after NIV and PaO2/FiO2 ＜ 185 mmHg (OR =1.7,95％ CI:1.243 ～ 2.365,P =0.041) 4 h after NIV independendy predicted NIV failure.Conclusions Dexmedetomidine might be considered as an effective and safe sedative for post-cardiac surgery patients with NIV intolerance.Early identification of predictors of NIV failure may facilitate early intervention.

Objective To investigate the effect of contralateral controlled functional electrical stimulation (CCFES) on the upper limb motor function in patients with acute and subacute hemiplegia.Methods Forty-eight patients with cerebral apoplexy were randomly divided into control,neuromuscular electrical stimulation (NMES) experiment,and CCFES experiment groups,with 24 patients in each group.The two groups received routine drug treatment and rehabilitation training.For 4 weeks (6 days/week),all the patients were assessed before and after treatment by using the Fugl-Meyer locomotor rating scale (FMA),Wolf motor function test (WMFT),wrist extension active joint activity evaluation (WEAROM),and modified Barthel index (MBI).Results were statistically analyzed,and curative effects were compared.Results Before treatment,no significant differences in FMA,WMFT,WEAROM,and MBI scores were found between the two groups.At the fourth week after the intervention,the FMA,WMFT,WEAROM,and MBI scores were all significantly increased (P ＜ 0.05).The FMA,WMFT,and WEAROM scores were all higher in the treatment group than in the control group,and the differences between the two groups were significant (P ＜ 0.05).Conclusion CCFES can effectively improve the upper limb motor function in patients with acute and subacute stroke.

Objective To evaluate the clinical application of human serum albumin for inpatients and provide evidence to its rational administration in our hospital .Methods 172 cases were randomly selected from the inpatients that treated with human serum albumin during the period from January to December 2010 by Mei-Kang clinical pharmacy workstation .To get the relating clinical ap-plication information from the choosing cases which were retrospectively analyzed .A comprehensive analysis was performed on age , sex, clinical departments, diagnosis, course of treatment, reasons of use, albumin concentration before using drugs etc.Results Most dosages of human serum albumin were used in the liver and gall surgery (26.1%), mainly for critical patients and cancer , Common individual consumption quantity ranged from 10 to 20 g.Most of patients adopted this drug for hypoproteinemia (38.9%), and most of them had a baseline serum albumin level at 10~30 g/L before using human serum albumin .Conclusion The application of human albumin in our hospital was far from perfect .The principle of effective , safe, economical and rational use of drugs should be adhere to reach the best efficacy application of human albumin .

Objective To evaluate the effects of high glucose on autophagy and apoptosis of podocyte and explore the signaling pathway in high glucose-induce podocyte autophagy.Methods Differentiated mouse podocytes were exposed to high glucose(30 mmol/L) or rapamycin (autophagy enhancer,1 μg/L) or LY294002 (a selective PI3K inhibitor,50 mmol/L) for 24 h.The formations of autophagy were observed by electron microscopy and acridine orange staining.Apoptosis was evaluated by flow cytometry.The expression of autophagy protein LC3-Ⅱ/Ⅰ and Beclin-1 as well as the phosphorylation of AKT and mTOR were examined by Western blotting analysis.Results High glucose induced podocytes apoptosis,increased autophagy and the expression of autophagy-associated proteins (all P ＜ 0.05).Rapamycin further increased the expression of LC3-Ⅱ and Beclin-1 protein (all P ＜ 0.05),but LY294002 inhibited partialiy the protein expression of LC3-Ⅱ and Beclin-1 induced by high glucose (both P ＜ 0.05).Treatment with rapamycin increased the phosphorylation of AKT,but reduced that of mTOR in podocytes.Moreover,LY294002 inhibited phosphorylation of both AKT and mTOR (both P ＜ 0.05).Conclusions High glucose promotes podocyte autophagy and apoptosis.High glucose-induced autophagy is mediated partly through PI3K-AKT-mTOR signaling pathway.

Objective To understand the current situation of smoking and quitting smoking in patients with cardiovascular disease. Methods 184 cases of inpatients or outpatients with cardiovascular disease treated in the First People's Hospital of Kunming were surveyed about quitting smoking, and the smoking and smoking cessation-related clinical features of patients with cardiovascular disease were analyzed. Results ( 1) Cardiovascular diseases in smokers was male-dominated (100%), mainly hypertension and/or coronary heart disease (179, 97.3%) . (2) Average age of starting smoking was 21.5, 97.8%of patients had smoked more than 10 years, with an average of 35.1 ±13.4 years, 69.6% of patients smoked ≥10 cigarettes/day, with an average of 16.3 ± 10.1 cigarettes/day, 65.8%of patients were in the low level of nicotine dependence, 81.5%of the patients thought that quitting smoking was important, 76.1% had quitting smoking ideas, 67.4% had confidence in the success of quitting smoking, 50.5%thought that it was difficult to quit smoking, 127 (69%) patients had seriously quit smoking. (3) 65 cases (51.2%) who seriously quit smoking had succeeded, 54 patients (83.1%) received varying degrees of medical staff advised to quit smoking, 62 cases (48.8%) in relapse, only 34 patients (54.8%) accepted medical personnel advised to quit. Two sets of chi-square test, p=0.000, prompted difference was statistically significant. Relapse reasons were pressure, craving and around other smokers. Conclusions Smoking patients with cardiovascular disease are mainly constituted by male patients with hypertension and/or coronary heart disease. Most of the patients recognize that quitting smoking is important, and have idea and seriously quit smoking. However, lack of confidence and smoking which has also become a lifestyle significantly affect the success of smoking cessation. The medical staffs' recommending smoking cessation persuasion can largely improve the success of smoking cessation for patients.
