The paper introduces Professor LIU Xing's clinical experience and characteristics of integrative acupuncture and medication in treatment of primary trigeminal neuralgia (PTN). It is believed that the essential pathogenesis of PTN is pathogenic wind, and qi and blood obstruction results from invasion of pathogenic wind. Hence, dispelling wind is the key principle of treatment. Palpation is done at first in the neck, face and buccal mucosal region to detect the masses in treatment. Acupotomy is operated at the masses distributed at Shangguan (GB3), Xiaguan (ST7) and the white line of buccal mucosa, so as to release masses. Additionally, five-wind points (Fengfu [GV16], bilateral Fengchi [GB20], Yifeng [TE17], Bingfeng [SI12] and Fengmen [BL12]), three-nape points (bilateral Naokong [GB19], Tianzhu [BL10] and Jianjing [GB21]) and three-governor-vessel points (Baihui [GV20], Zhiyang [GV9] and Yintang [GV24⁺]) are selected to dispel wind and stop pain. Besides, herbal decoction (wu feng tang) and blood-letting at ear apex are administered in combination. The integration of acupuncture and medication obtains a holistic effect on PTN by dispelling wind pathogen, and promoting qi and blood circulation.

The focus of green analytical chemistry (GAC) is to minimize the negative impacts of analytical procedures on human safety, human health, and the environment. Several factors, such as the reagents used, sample collection, sample processing, instruments, energy consumed, and the quantities of hazardous materials and waste generated during analytical procedures, need to be considered in the evaluation of the greenness of analytical assays. In this study, we propose a greenness evaluation metric for analytical methods (GEMAM). The new greenness metric is simple, flexible, and comprehensive. The evaluation criteria are based on both the 12 principles of GAC (SIGNIFICANCE) and the 10 factors of sample preparation, and the results are presented on a 0-10 scale. The GEMAM calculation process is easy to perform, and its results are easy to interpret. The output of GEMAM is a pictogram that can provide both qualitative and quantitative information based on color and number.

Myositis antibodies are divided into myositis-specific autoantibodies(MSA)and myositis-associated autoantibodies(MAA).There are heterogeneity in the mechanism,clinical features and prognosis of interstitial lung disease(ILD)in the different myositis antibodies.In MSA,anti-melanoma differentiation-related gene 5(MDA5)antibody and anti-aminoacyl synthetase(ARS)antibody are highly correlated with the occurrence of ILD.Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis.The progress of ILD in ARS+DM patients was slow,and the response to treatment is good,but it is easy to relapse.In MAA,anti-Ro52 antibodies often coexist with MSA antibodies,and clinical manifestation is closely related to coexisting antibodies.This review has summarized roles of myositis antibodies in ILD.

Objective:To compare the effects of different reference brain regions on the semi-quantitative SUV ratio (SUVR) of 18F-Florzolotau PET images of Alzheimer′s disease (AD). Methods:The 18F-Florzolotau PET images of 28 (13 males, 15 females, age (57.3±9.5) years) normal controls (NC), 19 patients (4 males, 15 females, age (73.3±7.3) years) with β-amyloid (Aβ)-positive mild cognitive impairment (MCI) and 40 patients (19 males, 21 females, age (61.9±9.1) years) with AD were collected from Huashan Hospital, Fudan University between November 2018 and July 2020. Six semi-quantitative reference brain regions were defined, including whole cerebellum (WC), cerebellar gray matter (GM), cerebellar white matter (WM), parametric estimation of reference signal intensity (PERSI), WC after partial volume correction (WC_pvc), cerebellar GM after partial volume correction (GM_pvc). SUVR was calculated for 14 ROIs, which included the whole brain defined by the automated anatomical labeling (AAL) template, fusiform, inferior temporal, lingual, middle temporal, occipital, parahippocampal, parietal, posterior cingulate, precuneus defined by the AAL template, and Meta ROI composed of the above brain regions, and braak_Ⅰ-Ⅱ, braak_Ⅲ-Ⅳ, braak_Ⅴ-Ⅵ defined by the Desikan Killiany template. AUC was used to evaluate the classification ability of SUVR, and the correlation between SUVR and clinical scale scores were assessed by Spearman rank correlation analysis. Results:The SUVRs of most brain regions showed a steady upward trend in the AD disease spectrum. In the classification task of NC and MCI, the overall performance of SUVR based on WC_pvc was relatively optimal (AUCs: 0.975-1.000). In the classification task of NC and AD, SUVRs of 10 ROIs based on the WC_pvc method showed the relatively best performance (AUCs: 0.976-1.000). The correlation between SUVR of fusiform based on cerebellar WM and mini-mental state examination (MMSE) score was the strongest ( rs=-0.72, P<0.001), and the SUVR of precuneus based on WC_pvc showed the strongest correlation with clinical dementia rating (CDR) score ( rs=0.78, P<0.001). Conclusion:The SUVR based on WC_pvc method performs well in classification and correlation tasks, and is recommended to be used in semi-quantification of 18F-Florzolotau PET images of AD.

Green analytical chemistry (GAC) focuses on mitigating the adverse effects of analytical activities on human safety, human health, and environment. In addition to the 12 principles of GAC, proper GAC tools should be developed and employed to assess the greenness of different analytical assays. The 15 widely used GAC metrics, i.e., national environmental methods index (NEMI), advanced NEMI, assessment of green profile (AGP), chloroform-oriented toxicity estimation scale (ChlorTox Scale), Analytical Eco-Scale, Green Certificate Modified Eco-Scale, analytical method greenness score (AMGS), green analytical procedure index (GAPI), ComplexGAPI, red-green-blue (RGB) additive color model, RGB 12 algorithm, analytical greenness calculator (AGREE), AGREE preparation (AGREEprep), HEXAGON, and blue applicability grade index (BAGI), are selected as the typical tools. This article comprehensively presents and elucidates the principles, characteristics, merits, and demerits of 15 widely used GAC tools. This review is helpful for researchers to use the current GAC metrics to assess the environmental sustainability of analytical assays.

Objective:To evaluate the influence of Helicobacter pylori ( H. pylori) infection on anxiety and depression in patients with chronic gastritis. Methods:From December 1 2020 to June 30 2021, 387 patients with chronic gastritis who visited the outpatient Department of Gastroenterology, the First Hospital Affiliated to Air Force Medical University were continuously recruited. According to the status of current H. pylori infection, the patients were divided into H. pylori uninfected group and H. pylori infected group. The general demographic information of patients was collected. Hamilton anxiety scale, Hamilton depression rating scale-24, Pittsburgh sleep quality index (PSQI) and gastrointestinal symptom rating scale (GSRS) were filled in. The detection rates of anxiety and depression were compared between the H. pylori uninfected group and the H. pylori infected group according to demographic characteristics. Chi-square test and multiple logistic regression analysis were used for statistical analysis. Results:Finally, 360 patients with chronic gastritis were enrolled, including 200 patients in H. pylori uninfected group and 160 patients in H. pylori infected group. The detection rates of anxiety and depression of the H. pylori infected group were both higher than those of the H. pylori uninfected group (48.1%, 77/160 vs. 30.0%, 60/200; 25.0%, 40/160 vs. 12.5%, 25/200), and the differences were statistically significant ( χ2=12.39 and 9.39, P<0.001 and=0.002). The detection rate of anxiety of male patients in the H. pylori infected group was higher than that in the H. pylori uninfected group (45.1%, 32/71 vs. 24.5%, 27/110); the detection rate of depression of female patients in the H. pylori infected group was higher than that in the H. pylori uninfected group (30.3%, 27/89 vs. 11.1%, 10/90), and the differences were statistically significant ( χ2=8.27 and 10.09, P=0.004 and 0.001). The detection rates of anxiety and depression of patients less than 48 years old in the H. pylori infected group were both higher than those in the H. pylori uninfected group (46.2%, 37/80 vs. 21.9%, 21/96; 20.0%, 16/80 vs. 7.3%, 7/96), and the differences were statistically significant ( χ2=11.73 and 6.20, P=0.001 and 0.013). The detection rates of anxiety and depression of the patients with high school education and below in the H. pylori infected group were higher than those in the H. pylori uninfected group (56.5%, 48/85 vs. 31.7%, 38/120; 32.9%, 28/85 vs. 14.2%, 17/120), and the differences were statistically significant ( χ2=12.57 and 10.24, P<0.001 and =0.001). The results of multivariate analysis showed that H. pylori infection, history of hypertension, PSQI score ≥8, GSRS score ≥7, chronic superficial gastritis and chronic atrophic gastritis were independent risk factors of anxiety in patients with chronic gastritis( P<0.001, =0.013, =0.001, <0.001, =0.036, =0.021), and the risk of anxiety of patients with H. pylori infection was 2.509 times as much as that in uninfected patients (95% confidence interval 1.512 to 4.163). H. pylori infection, PSQI score ≥8, GSRS score≥7, and having overnight dish ≥3 times per week all were independent risk factors of depression in patients with chronic gastritis( P=0.004, =0.002, <0.001, =0.001). The risk of depression in patients with H. pylori infection was 2.563 times as much as that in uninfected patients (95% confidence interval 1.356 to 4.846). Conclusion:H. pylori infection is correlated to anxiety and depression in patients with chronic gastritis, and it is an independent risk factor of anxiety and depression in patients with chronic gastritis.

The construction of efficient and stable Lactobacillus expression vector is critical for strain improvement and development of customized strains. In this study, four endogenous plasmids were isolated from Lacticaseibacillus paracasei ZY-1 and subjected to functional analysis. The Escherichia coli-Lactobacillus shuttle vectors pLPZ3N and pLPZ4N were constructed by combining the replicon rep from pLPZ3 or pLPZ4, the chloramphenicol acetyltransferase gene cat from pNZ5319 and the replicon ori from pUC19. Moreover, the expression vectors pLPZ3E and pLPZ4E with the promoter P_ldh3 of lactic acid dehydrogenase and the mCherry red fluorescent protein as a reporter gene were obtained. The size of pLPZ3 and pLPZ4 were 6 289 bp and 5 087 bp, respectively, and its GC content, 40.94% and 39.51%, were similar. Both shuttle vectors were successfully transformed into Lacticaseibacillus, and the transformation efficiency of pLPZ4N (5.23×10²-8.93×10² CFU/μg) was slightly higher than that of pLPZ3N. Furthermore, the mCherry fluorescent protein was successfully expressed after transforming the expression plasmids pLPZ3E and pLPZ4E into L. paracasei S-NB. The β-galactosidase activity of the recombinant strain obtained from the plasmid pLPZ4E-lacG constructed with P_ldh3 as promoter was higher than that of the wild-type strain. The construction of shuttle vectors and expression vectors provide novel molecular tools for the genetic engineering of Lacticaseibacillus strains.

Objective:To investigate the anxiety and depression in patients with gallbladder polyps, gallbladder stones and post-cholecystectomy.Methods:From December 2020 to August 2021, consecutive patients who visited the Department of Gastroenterology, First Affiliated Hospital of Air Force Medical University, were enrolled and divided into normal gallbladder group, gallbladder polyp group, gallbladder stone group and post-cholecystectomy group, with 100 patients in each group. Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were used to evaluate patients′ anxiety or depression. Quality of life, sleep quality and severity of gastrointestinal symptom were assessed by short form 36 (SF-36), Pittsburgh sleep quality index (PSQI) scale and gastrointestinal symptom rating scale (GSRS) respectively. The incidence of anxiety or depression of patients in the 4 groups were compared, and the related risk factors of anxiety and depression were analyzed. Chi-square test and multiple logistic regression were used for statistical analysis.Results:Among 400 patients, 89 patients (22.2%) suffered from anxiety; and the incidences of anxiety of normal gallbladder group, gallbladder polyp group, gallbladder stone group and post-cholecystectomy group were 9.0% (9/100), 19.0% (19/100), 25.0% (25/100) and 36.0% (36/100) respectively. There was statistically significant difference in the incidence of anxiety among the 4 groups ( χ2=22.12, P<0.001). The incidence rates of anxiety of the gallbladder polyp group, gallbladder stone group and post-cholecystectomy group were all higher than that of the normal gallbladder group, and the differences were all statistically significant ( χ2=4.15, 9.07 and 20.90, P=0.042, 0.003 and <0.001). The incidence of anxiety of post-cholecystectomy group was higher than that of gallbladder polyp group, and the difference was statistically significant ( χ2=7.25, P=0.007). Among the 400 patients, 70 patients (17.5%) suffered from depression. The incidence rates of depression of the normal gallbladder group, gallbladder polyp group, gallbladder stone group and post-cholecystectomy group were 5.0% (5/100), 10.0% (10/100), 24.0% (24/100) and 31.0% (31/100) respectively. There was statistically significant difference in the incidence of depression among the 4 groups ( χ2=30.27, P<0.001). The incidences of depression of the gallbladder stone group and post-cholecystectomy group were both higher than that of the normal gallbladder group and gallbladder polyp group, and the differences were statistically significant ( χ2=14.56, 22.90, 6.94 and 13.53, P<0.001, <0.001, =0.008 and <0.001). The results of multivariate analysis showed that history of cholecystectomy, history of coronary heart disease, consumption of overnight food ≥3 times per week, PSQI score ≥ 8 and GSRS score ≥9 were independent risk factors for anxiety ( OR, 95%confidence interval: 4.02, 1.60 to 10.13; 10.01, 2.15 to 46.68; 4.15, 1.87 to 9.19; 4.69, 2.58 to 8.52; 3.02, 1.64 to 5.58; P=0.003, 0.003, <0.001, <0.001, and <0.001). Gallbladder stones history of cholecystectomy, consumption of overnight food ≥3 times per week, consumption of fresh fruit < 200 g/d, PSQI score ≥8 and GSRS score ≥9 were independent risk factors for depression ( OR, 95%confidence interval: 4.40, 1.38 to 14.06; 4.97, 1.54 to 16.12; 4.23, 1.61 to 11.08; 3.78, 1.32 to 10.85; 5.59, 2.78 to 11.27, 4.19, 1.94 to 9.04; P=0.012, 0.007, 0.003, 0.014, <0.001 and <0.001). Conclusions:The incidences of anxiety and depression in patients with gallbladder stones or post-cholecystectomy are higher than that of people with normal gallbladder. A history of cholecystectomy is the independent risk factor for anxiety and depression. Gallbladder stones is the independent risk factor of depression. Clinical attention should be paid to the mental state of patients with gallbladder polyps, gallbladder stones, especially post-cholecystectomy.

Genome editing is a genetic manipulation technique that can modify DNA sequences at the genome level, including insertion, knockout, replacement and point mutation of specific DNA fragments. The ultimate principle of genome editing technology relying on engineered nucleases is to generate double-stranded DNA breaks at specific locations in genome and then repair them through non-homologous end joining or homologous recombination. With the intensive study of these nucleases, genome editing technology develops rapidly. The most used nucleases include meganucleases, zinc finger nucleases, transcription activator-like effector nucleases, and clustered regularly interspaced short palindromic repeats associated Cas proteins. Based on introducing the development and principles of above mentioned genome editing technologies, we review the research progress of CRISPR/Cas9 system in the application fields of identification of gene function, establishment of disease model, gene therapy, immunotherapy and its prospect.

Primary liver cancer (PLC) is an aggressive tumor and prone to metastasize and recur. According to pathological features, PLC are mainly categorized into hepatocellular carcinoma, intrahepatic cholangiocarcinoma, mixed hepatocellular cholangiocarcinoma, and fibrolamelic hepatocellular carcinoma, etc. At present, surgical resection, radiotherapy and chemotherapy are still the main treatments for PLC, but the specificities are poor and the clinical effects are limited with a 5-year overall survival rate of 18%. Liver cancer stem cells (LCSCs) are a specific cell subset existing in liver cancer tissues. They harbor the capabilities of self-renewal and strong tumorigenicity, driving tumor initiation, metastasis, drug resistance and recurrence of PLC. Therefore, the identification of molecular markers and the illustration of mechanisms for stemness maintenance of LCSCs can not only reveal the molecular mechanisms of PLC tumorigenesis, but also lay a theoretical foundation for the molecular classification, prognosis evaluation and targeted therapy of PLC. The latest research showed that the combination of 5-fluorouracil and CD13 inhibitors could inhibit the proliferation of CD13+ LCSCs, thereby reducing overall tumor burden. Taken together, LCSCs could be the promising therapeutic targets of PLC in the future. This review summarizes the latest progress in molecular markers, mechanisms for stemness maintenance and targeted therapies of LCSCs.
