With the improved understanding of driver mutations in non-small cell lung cancer (NSCLC), expanding the targeted therapeutic options improved the survival and safety. However, responses to these agents are commonly temporary and incomplete. Moreover, even patients with the same oncogenic driver gene can respond diversely to the same agent. Furthermore, the therapeutic role of immune-checkpoint inhibitors (ICIs) in oncogene-driven NSCLC remains unclear. Therefore, this review aimed to classify the management of NSCLC with driver mutations based on the gene subtype, concomitant mutation, and dynamic alternation. Then, we provide an overview of the resistant mechanism of target therapy occurring in targeted alternations ("target-dependent resistance") and in the parallel and downstream pathways ("target-independent resistance"). Thirdly, we discuss the effectiveness of ICIs for NSCLC with driver mutations and the combined therapeutic approaches that might reverse the immunosuppressive tumor immune microenvironment. Finally, we listed the emerging treatment strategies for the new oncogenic alternations, and proposed the perspective of NSCLC with driver mutations. This review will guide clinicians to design tailored treatments for NSCLC with driver mutations.

OBJECTIVE: To investigate the molecular mechanisms underlying the beneficial effect of electroacupuncture (EA) in experimental models of Alzheimer's disease (AD) in vivo. METHODS: Senescence-accelerated mouse prone 8 (SAMP8) mice were used as AD models and received EA at Yingxiang (LI 20, bilateral) and Yintang (GV 29) points for 20 days. For certain experiments, SAMP8 mice were injected intravenously with human fibrin (2 mg). The Morris water maze test was used to assess cognitive and memory abilities. The changes of tight junctions of blood-brain barrier (BBB) in mice were observed by transmission electron microscope. The expressions of fibrin, amyloid- β (Aβ), and ionized calcium-binding adapter molecule 1 (IBa-1) in mouse hippocampus (CA1/CA3) were detected by reverse transcription-quantitative polymerase chain reaction (qRT-PCR), Western blot or immunohistochemical staining. The expression of fibrin in mouse plasma was detected by enzyme-linked immunosorbent assay. The expressions of tight junction proteins zonula occludens-1 and claudin-5 in hippocampus were detected by qRT-PCR and immunofluorescence staining. Apoptosis of hippocampal neurons was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. RESULTS: Fibrin was time-dependently deposited in the hippocampus of SAMP8 mice and this was inhibited by EA treatment (P<0.05 or P<0.01). Furthermore, EA treatment suppressed the accumulation of Aβ in the hippocampus of SAMP8 mice (P<0.01), which was reversed by fibrin injection (P<0.05 or P<0.01). EA improved SAMP8 mice cognitive impairment and BBB permeability (P<0.05 or P<0.01). Moreover, EA decreased reactive oxygen species levels and neuroinflammation in the hippocampus of SAMP8 mice, which was reversed by fibrin injection (P<0.05 or P<0.01). Mechanistically, EA inhibited the promoting effect of fibrin on the high mobility group box protein 1 (HMGB1)/toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE)/nicotinamide adenine dinucleotide phosphate (NADPH) signaling pathways (P<0.01). CONCLUSION EA may potentially improve cognitive impairment in AD via inhibition of fibrin/A β deposition and deactivation of the HMGB1/TLR4 and RAGE/NADPH signaling pathways.

AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P<0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃～15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

Tuberculosis is a serious zoonotic disease causing approximately 10 million new cases worldwide every year.The emergence of various drug-resistant strains of Mycobacterium tuberculosis is currently an important challenge intuberculosispre-vention and control,and an urgent need exists to develop new anti-tuberculosis drugs to treat drug-resistant tuberculosis and shorten the treatment time.The discovery of drug targets is a bottleneck inthe development of new anti-tuberculosis drugs.At present,the widely reported drug targets for tuberculosis include primarily new targets related to the biosynthesis of Mycobac-terium tuberculosis components and immune metabolic pathways.In addition,host-directed therapiestargeting the host immune system have become a research hotspot in recent years.Adjuvant host-directed therapies can enhance the therapeutic effect of tuberculosis and shorten treatment times by affecting granuloma formation,autophagy,host immune metabolism and the intra-cellular killing mechanism,as well as regulating pulmonary inflammation.The discovery of these new targets provides new ide-as for the future development of safe and effective new anti-tuberculosis drugs.

OBJECTIVE To observe the effect of electroacupuncture(EA)on sleep quality and serum levels of dopamine(DA)and γ-aminobutyric acid(GABA)in patients with chronic insomnia and emotional disorders.METHODS 62 cases of chronic insom-nia with emotional disorders were randomly divided into treatment group and control group,32 cases in each group.Both groups were given sleep education,the treatment group was treated with electroacupuncture,and the control group was treated with blunt non-trans-dermal shallow needling.Both groups were treated for 4 weeks.The Pittsburgh sleep quality index(PSQI),insomnia severity index(ISI),Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD-17)were used to evaluate the sleep quality,insomni-a,anxiety and depression of the two groups before and after treatment.Serum levels of dopamine and γ-aminobutyric acid were meas-ured by ELISA.RESULTS After treatment,the PSQI total score and each factor score of the treatment group decreased(P<0.01,P<0.05),and the ISI,HAMA,HAMD-17 scale scores were significantly lower than those before treatment(P<0.01).Compared with the control group,the scores of each scale in the treatment group were significantly lower(P<0.01).After treatment,the serum levels of DA and GABA in the treatment group were higher than those before treatment and in the control group(P<0.01).CONCLUSION Electroacupuncture is effective in improving the sleep quality of patients with chronic insomnia and emotional disorders,and can re-lieve their anxiety and depression.Its mechanism may be related to promoting the expression of DA,GABA and other transmitters in peripheral blood.

Under the guidance of the traditional Chinese medicine(TCM) theory of "Zangfu-organs of spleen and stomach" and the modern theory of "microbiota-gut-brain axis", this study explored the effects of Nardostachys jatamansi on the gut microbiota of rats with Parkinson's disease(PD). The 40 SD rats were randomly divided into the control group, PD model group, levodopa group, and Nardostachys jatamansi ethanol extract group. The PD model was established by subcutaneous injection of rotenone in the neck and back area. After 14 days of intragastric administration, the PD rats' behaviors were analyzed through open field test, inclined plane test, and pole test. After the behavioral tests, the striatum, colon, and colon contents of rats in each group were collected. Western blot was employed to detect the protein expression of tyrosine hydroxylase(TH) and α-synuclein(α-syn) in striatum and that of α-syn in colon. Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and nuclear factor-kappa B(NF-κB) in striatum and colon. High-throughput sequencing of 16 S rRNA gene was conducted to detect the differences in microbial diversity, abundance, differential phyla, and dominant bacteria of rats between groups. The results indicated that Nar. ethanol extract could relieve dyskinesia, reverse the increased levels of α-syn, TNF-α, IL-1β, and NF-κB in striatum, and improve the protein expression of TH in striatum of PD rats. The α diversity analysis indicated a significant decrease in diversity and abundance of gut microbiota in the PD model. The results of linear discriminant analysis effect size(LEfSe) of dominant bacteria indicated that Nardostachys jatamansi ethanol extract increased the relative abundance of Clotridiaceae, Lachnospiraceae, and Anaerostipes, and reversed the increased relative abundance of Proteobacteria, Gammaproteobacteria, Enterobacteriaceae, and Escherichia-Shigella in PD model group to exhibit the neuroprotective effect. In summary, the results indicated that Nar. ethanol extract exert the therapeutic effect on PD rats. Specifically, the extract may regulate gut microbiota, decrease the levels of proinflammatory cytokines, and reduce the protein aggregation of α-syn in the colon and striatum to alleviate intestinal inflammation and neuroinflammation. This study provides a basis for combining the theory of "Zangfu-organs of spleen and stomach" with the theory of "microbiota-gut-brain axis" to treat PD.

OBJECTIVE: To observe the clinical effect of electroacupuncture (EA) on aged insomnia, and explore its possible mechanism. METHODS: A total of 60 patients with aged insomnia were randomly divided into an EA group (30 cases) and a sham EA group (30 cases, 1 case dropped off). The patients in the EA group were treated with acupuncture at Baihui (GV 20), Yintang (GV 29), Shenmen (HT 7), Sanyinjiao (SP 6), Xinshu (BL 15) and Shenshu (BL 23), and EA was used at Baihui (GV 20) and Yintang (GV 29), with intermittent wave, 2 Hz in frequency. In the sham EA group, the acupoints and the EA connection acupoints were the same as those in the EA group, 2-3 mm in depth, but no current was connected. The intervention was given 30 min each time, once every other day, 3 times a week for 4 weeks in the both groups. Before and after treatment, the Pittsburgh sleep quality index (PSQI) and Montreal cognitive assessment (MoCA) scale were used to assess sleep quality and cognitive function, and serum melatonin (MT) and dopamine (DA) levels were detected. RESULTS: After treatment, the total score and sub-item scores of PSQI in the EA group were lower than those before treatment ( CONCLUSION Electroacupuncture can improve sleep quality and cognitive function in aged insomnia patients, and its mechanism may be related to regulating serum MT and DA levels.

By preparing 15 batches of substance benchmarks of Taohong Siwu Decoction, the methodology of the characteristic spectrums of substance benchmarks was established. The paste-forming rate range, the contents and the transfer rate range of the index components, hydroxy safflower yellow A, ferulic acid and paeoniflorin, the characteristic peaks and the similarity range of the characteristic spectrums of Taohong Siwu Decoction were determined to define key quality attributes of substance benchmarks of Taohong Siwu Decoction.In the 15 batches of substance benchmarks of Taohong Siwu Decoction, the similarity of characteristic spectrums was higher than 0.9. Furthermore, based on summarization of the characteristic peak information, there were 13 characteristic peaks in the whole decoction. Baishao had three characteristic peaks, Honghua had seven characteristic peaks, and Chuanxiong and Danggui had three characteristic peaks. The paste-forming rate of the 15 batches of substance benchmarks was controlled at 33.11%-40.62%. The content of hydroxy safflower yellow A was 0.129%-0.203%, with the average transfer rate of 16.596%±0.669%.The content of ferulic acid was 0.043%-0.055%, with the average transfer rate of 20.489%±1.772%.The content of paeoniflorin was 0.676%-0.943%, with the average transfer rate of 29.112%±3.273%.The quality value transfer of substance benchmarks of classical prescription Taohong Siwu Decoction was analyzed by the combination of characteristic spectrums, paste-forming rate and the content of index components. The established substance benchmark quality evaluation method was stable and feasible, and could provide a basis for quality control and subsequent development of relevant preparations of Taohong Siwu Decoction.

Six month old Cinnamomum cassia seedlings were used to simulate drought stress with polyethylene glycol(PEG 6000). The physiological indicators(osmotic substances, antioxidant enzymes, etc.) and chemical components of seedlings under different drought levels and the correlation between the two were studied. The results showed that the chlorophyll content and relative water content decreased gradually with the increase of PGE 6000(0, 5%, 10%, 15%) concentration and time(3, 5, 7 d), while the soluble protein content, soluble sugar content and catalase(CAT) activity increased, but the rising rate slowed down with the time. The activities of peroxidase(POD), superoxide dismutase(SOD), malondialdehyde(MDA) and proline content increased at first and then decreased. The content of coumarin, cinnamaldehyde, cinnamic acid and dimethoxycinnamaldehyde decreased, while the content of cinnamyl alcohol continued to increase.Under drought stress, the fluorescence signals of reactive oxygen species and no contents in roots of C. cassia seedlings were significantly stronger than those of the control.Further correlation analysis showed that coumarin content, di-methoxycinnamaldehyde content and osmoregulation substance content were significantly negatively correlated(P<0.05), cinnamic acid content was significantly negatively correlated with POD and SOD activities(P<0.01).It was found that C. cassia seedlings showed a certain degree of drought tolerance under short-term or mild drought stress, but if the drought exceeded a certain degree, the physiological metabolism of the seedlings would be unbalanced.
