Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective To investigate the patterns of traditional Chinese medicine(TCM)syndrome differentiation and treatment for dengue fever by using R language data visualization technology,so as to provide reference for TCM syndrome differentiation and treatment of dengue fever.Methods The related literature of dengue fever treated by Chinese medicine was retrieved from CNKI,Wanfang Data,and VIP.R-Studio software was used to conduct descriptive statistical analysis of the TCM syndromes,treatment methods,prescriptions and Chinese medicine in the literature of dengue fever treated by oral use of Chinese medicine.Based on Apriori algorithm,association rule mining and cluster analysis were carried out to explore the TCM syndrome and treatment patters of dengue fever.Results A total of 176 prescriptions for effective cases were extracted,and the included literature involved 29 syndromes,73 TCM treatment methods,56 classical prescriptions and 35 self-formulated prescriptions,and 179 Chinese medicinals.The syndrome of comorbidity of defense phase and qi phase and the syndrome of blazing of both qi phase and nutrient phase were the high-frequency syndromes of dengue fever treated by oral use of Chinese medicine.The high-frequency treatment methods covered heat-clearing therapy,toxin-removing therapy,blood-cooling therapy and dampness-resolving therapy.Qingwen Baidu Decoction was the most frequently-used prescription.Glycyrrhizae Radix et Rhizoma,Forsythiae Fructus,Scutellariae Radix,Gypsum Fibrosum,and Lonicerae Japonicae Flos were the frequently-used Chinese medinals.There were three drug combinations containing Paeoniae Radix Rubra,Moutan Cortex,and Rehmanniae Radix,and their correlation of association rules was the highest.Bubali Cornu,Moutan Cortex,Paeoniae Radix Rubra,Rehmanniae Radix,Lonicerae Japonicae Flos,Forsythiae Fructus,Gypsum Fibrosum,Scutellariae Radix,Anemarrhenae Rhizoma,and Glycyrrhizae Radix et Rhizoma were the core Chinese medicinals for the treatment of dengue fever.Conclusion The TCM syndromes of dengue fever are predominated by the syndrome of comorbidity of defense phase and qi phase and the syndrome of blazing of both qi phase and nutrient phase.The treatment of dengue fever with TCM is based on the principle of clearing heat toxin from the qi phase,cooling the nutrient-blood excess heat,resolving pathogenic dampness,and nourishing qi and yin.The treatment focuses on clearing qi phase and blood phase,and the application of removing stasis in febrile diseases should be stressed,thus to block the progression of the disease in time.

This study evaluated the scientific nature and effectiveness of iterative optimization of prevention and control measures for local outbreaks caused by the BA.2 and BA.5.2 COVID-19 strains in Fujian Province in 2022,to provide a scientif-ic basis for responding to future new or recurrent respiratory infectious diseases.According to the theory of infectious disease dynamics,relevant information regarding the local epidemic situation caused by the BA.2 sub-type Omicron virus strain in March 2022 and BA.5.2 sub-type Omicron virus strain in October 2022 in Fujian Province was collected.The susceptible exposed infectious removed(SEIAR)model of COVID-19 infection with a latent period and asymptomatic infected persons was used to analyze the transmission dynam-ics of two local epidemic situations,and evaluate the preven-tion and control effects.The incubation period of the BA.2 epidemic was 3 days(1～9 days),the intergenerational inter-val was 3 days(1～5 days),and the initial Rt was 3.0(95％CI:2.7～3.3).The incubation period of the BA.5.2 epidemic was 2 days(1～6 days),the intergenerational interval was 1 day(0～2 days),and the initial R,was 1.9(95％CI:1.7～2.1).The fittingresults for the BA.2 and BA.5.2 epidemics were good,and no statistical difference was observed between the predic-ted and actual numbers of cases(x2BA.2=31.53,x2BA.5.2=27.88,P＞0.05).If an emergency response had not been initiated,the BA.2 epidemic would have continued to spread andpeak on April 7th,with an estimated 638 035 cases.The BA.5.2 epidemic would have rapidly spread,reaching a peak on November 14th,with an estimated 685 940 cases.If one incubation period were detected early,the scale of the BA.2 epidemic would have decreased by 25.73％;if two incubation periods were detected early,the scale would have decreased by 79.56％,and if one incubation period had been delayed,the scale would have expanded by 13.72％.If one incubation period had been detected early in the BA.5.2 epidemic,the scale would have decreased by 35.04％;if two incubation periods had been detected early,the scale would have decreased by 92.47％;and if one incubation period had been delayed,the scale would have increased by 19.75％.The guiding ideology,and the prevention and control measures for handling two local epidemics were optimized and iterated.Our study indicated that implementing the"four early"measures ef-fectively decreased the scale of the epidemic,and earlier detection was associated with more significant control effects.This study provides valuable information for the prevention and control of new or recurrent respiratory infectious diseases.

Objective To assess the accuracy of CT features of lung nodules (≤3 cm) in predicting the accuracy of the pathological subtype and degree of infiltration of adenocarcinoma. Methods We retrospectively analyzed the clinical data of 333 patients with non-cavitary pulmonary nodules diagnosed as adenocarcinoma by surgery and pathology in the China-Japan Friendship Hospital from 2011 to 2018, including 108 males and 225 females, aged 16-82 (59.57±10.16) years. The basic clinical data and CT characteristics of the patients were recorded. Results When the average CT value was ≥507 Hu, the maximum diameter of the lung window was ≥14.5 mm, and the solid component ratio was ≥5.0%, it indicated more likely the invasive adenocarcinoma (IAC). The higher the average CT value of the nodule, the larger the maximum diameter of the lung window, and the more solid components, the higher the degree of infiltration. CT morphological features (including burrs, lobes, vascular signs, bronchial signs, pleural stretch or depression signs) were more common in IAC. Among them, burrs were more common in acinar adenocarcinoma and papillary adenocarcinoma. In invasive adenocarcinoma, the higher the risk of recurrence of the pathological subtype, the greater the average CT value. When the average CT value of IAC was >−106 Hu, and the proportion of solid components was ≥70.5%, the histological subtypes were more inclined to micropapillary/solid predominant adenocarcinoma. Conclusion The evaluation of CT features of lung nodules can improve the predictive value of histopathological types of lung adeno-carcinoma, thereby optimizing clinical treatment decisions and obtaining more ideal therapeutic effects.

OBJECTIVE: To assess the efficacy and safety of Bushen Huoxue Formula (BSHXF) for the treatment of discogenic low-back pain (DLBP). METHODS: This was a parallel, double-blind, randomized, clinical trial performed between May 2019 and June 2020. Seventy patients were assigned by computerized random number table to the treatment group (lumbar traction and BSHXF, 35 cases) or the control group (lumbar traction and placebo, 35 cases). The patients received intervention for 3 weeks. Assessment was conducted before treatment and at week 1, 2, 3 during treatment. Primary outcome was the self-reported score of Oswestry Disability Index (ODI). Secondary outcomes included Visual Analog Scale (VAS), clinical efficacy rate by minimal clinically important difference (MCID) as well as lumbar tenderness, muscle tone and lumbar spine mobility. Adverse reactions were recorded. Follow-up was performed at 1 and 3 months after the end of treatment. RESULTS: In the treatment group, ODI score was significantly decreased compared with baseline (P<0.05) and the control group at 2- and 3- week treatment. Similarly, VAS score decreased compared with the baseline (P<0.05) and was lower than that in the control group at 2- and 3- week treatment (P<0.05). The clinical efficacy rate of the treatment group was higher than that of the control group after treatment [32.35% (11/34) vs. 3.13% (1/32), P<0.05). Moreover, the tenderness, and muscle tone, as well as the back extension and left flexion in lumbar spine mobility in the treatment group at 3-week treatment were significantly improved compared with the control group (P<0.05). Follow-up showed that at 1-month after treatment, the treatment group had better outcomes than the control group with regard to a total score of ODI and VAS scores, as well as clinical efficacy rate (all P<0.05). Moreover, VAS score was still significantly lower than the control group at 3-month follow-up (P<0.05). No adverse reactions were reported during the study. CONCLUSION BSXHF combined with lumbar traction can significantly improve the clinical symptoms including pain intensity, functionality, muscle tone, and lumbar spine mobility in DLBP patients.

OBJECTIVE: To compare the safety of low-dose cyclophosphamide and high-dose cyclophosphamide in the treatment of systemic lupus erythematosus (SLE). METHODS: A total of 1 022 patients with systemic lupus erythematosus from 24 hospitals in China between March 2017 to July 2018 were enrolled. Their clinical manifestations, laboratory tests, adverse events, reasons for stopping receiving intravenous cyclophosphamide and comorbidities were collected. Among them, 506 SLE patients received short-interval low-dose intravenous cyclophosphamide therapy (SILD IV-CYC, 400 mg every two weeks), and 256 patients underwent high-dose cyclophosphamide therapy (HD IV-CYC, 500 mg/m² of body surface area every month), the side effects between the two groups were compared, the remaining 260 SLE patients were treated with IV-CYC irregularly. Moreover, a total of 377 patients in SILD IV-CYC group and 214 patients in HD IV-CYC group had medical records of the reasons for stopping recei-ving IV-CYC. The reasons for stopping receiving IV-CYC in these two groups were analyzed. RESULTS: In this study, only 40.27%(238/591)of the SLE patients stopped receiving intravenous cyclophosphamide for the causes of disease improvement, however, up to 33.67% (199/591) of the patients for the reason of drug-related side effects. There were 83 patients out of 214 (38.79%) with high-dose intravenous cyclophosphamide treatment who stopped receiving IV-CYC for the drug-related side effects, which was significantly higher than that in the low-dose cyclophosphamide group (30.77%, 116/337, P=0.048). Of theses 506 patients in SILD IV-CYC group, 88 (17.39%) patients experienced gastrointestinal reactions, 66 (13.04%) suffered from infections, 49 (9.68%) had myelosuppression and 68 (13.44%) had alopecia, respectively. Among the 256 patients in the HD IV-CYC group, 80 (31.25%) experienced gastrointestinal reactions, 57 (22.27%) suffered from infections, 51 (19.92%) had myelosuppression and 49 (19.14%) had alopecia. Moreover, 71 (25.18%) of 282 female patients with age between 16 to 45 years in SILD IV-CYC group had abnormal menstruation, while menstrual disorder occurred in 39.72% (56/141) patients of HD IV-CYC group. There was no difference of drug-induced hepatic injury, hemorrhagic cystitis and fatigue between the two groups. CONCLUSION Low-dose cyclophosphamide showed a lower prevalence of adverse events than high-dose cyclophosphamide in systemic lupus erythematosus patients.

Objective    To investigate the predictive value of preoperative radiological features on spread through air spaces (STAS) in stage cⅠA lung adenocarcinoma with predominant ground-glass opacity, and to provide a basis for the selection of surgical methods for these patients. Methods    The clinical data of 768 patients with stage cⅠA lung adenocarcinoma undergoing operation in our hospital from 2017 to 2018 were reviewed, and 333 early stage lung adenocarcinoma patients with predominant ground-glass opacity were selected. There were 92 males and 241 females, with an average age of 57.0±10.0 years. Statistical analysis was performed using SPSS 22.0. Results    STAS-positive patients were mostly invasive adenocarcinoma (P=0.037), and had more micropapillary component (P<0.001) and more  epidermal growth factor receptor (EGFR) gene mutations (P=0.020). There were no statistically significant differences between the STAS-positive and STAS-negative patients in other clinicopathological features. Univariate analysis showed that the maximum diameter of tumor in lung window (P=0.029), roundness (P=0.035), maximum diameter of solid tumor component in lung window (P<0.001), consolidation/tumor ratio (CTR, P<0.001), maximum area of the tumor in mediastinum window (P=0.001), tumor disappearance ratio (TDR, P<0.001), average CT value (P=0.001) and lobulation sign (P=0.038) were risk factors for STAS positive. Multivariate logistic regression analysis showed that the CTR was an independent predictor of STAS (OR=1.05, 95%CI 1.02 to 1.07, P<0.001), and the area under the receiver operating characteristic (ROC) curve was 0.71 (95%CI 0.58 to 0.85, P=0.002). When the cutoff value was 19%, the sensitivity of predicting STAS was 66.7%, and the specificity was 75.2%. Conclusion    CTR is a good radiological feature to predict the occurrence of STAS in early lung adenocarcinoma with predominant ground-glass opacity. For the stage cⅠA lung adenocarcinoma with predominant ground-glass opacity and CTR ≥19%, the possibility of STAS positive is greater, and sublobar resection needs to be carefully considered.

Objective:To analyze the law of distant metastasis in patients with small lung adenocarcinoma with different CT findings, and to explore the feasibility of different preoperative examination methods for small lung adenocarcinoma with different imaging characteristics.Methods:Clinicopathological data of cT1a-cN0 lung adenocarcinoma patients admitted to the respiratory center of China-Japan Hospital from January 2017 to December 2018 were retrospectively collected. A total number of 785 patients were included, including 289 males and 496 females. SPSS 22.0 was used for statistical analysis.Results:A total number of 785 patients were included in this study, including 287 pure ground-glass nodule (GGN) patients, 111 GGN predominant patients, 221 solid predominant patients and 166 solid nodule patients. Among the included patients, 8 had distant metastasis, including 6 with bone metastasis, 1 with brain metastasis and 1 with brain and adrenal metastasis. No distant metastasis was observed in the patients with pure GGN and GGN predominant nodule, while 1 solid predominant patients had distant metastasis, and 7 patients with solid nodules had distant metastasis. The probability of distant metastasis was 0.5% for the solid predominant patients and 4.2% for the solid nodule patients. Univariate analysis results showed that CEA level ( P=0.030), the largest diameter of the lung window tumor ( P=0.003), the largest diameter of the solid component of the lung window tumor ( P<0.001), the largest area of the lung window tumor ( P=0.002), mediastinal window tumor maximum area ( P<0.001), CTR ( P<0.001), TDR ( P<0.001), and pleural indentation sign ( P=0.037) were risk factors for distant metastases. Multivariate analysis showed that CEA ( OR=1.019, 95% CI: 1.002-1.037, P=0.028) and TDR ( OR=0.000, 95% CI: 0.000-0.310, P=0.001) were independent risk factors of distant metastasis. Conclusion:For patients with pure GGN and GGN predominant nodule, preoperative examination could not be required, but for pure solid nodules, it is necessary to perform relevant preoperative examination including skull MRI before surgery to exclude distant metastasis.

Epithelial and stromal tissues are components of the tumor microenvironment and play a major role in tumor initiation and progression. Distinguishing stroma from epithelial tissues is critically important for spatial characterization of the tumor microenvironment. Here, we propose BrcaSeg, an image analysis pipeline based on a convolutional neural network (CNN) model to classify epithelial and stromal regions in whole-slide hematoxylin and eosin (H&E) stained histopathological images. The CNN model is trained using well-annotated breast cancer tissue microarrays and validated with images from The Cancer Genome Atlas (TCGA) Program. BrcaSeg achieves a classification accuracy of 91.02％, which outperforms other state-of-the-art methods. Using this model, we generate pixel-level epithelial/stromal tissue maps for 1000 TCGA breast cancer slide images that are paired with gene expression data. We subsequently estimate the epithelial and stromal ratios and perform correlation analysis to model the relationship between gene expression and tissue ratios. Gene Ontology (GO) enrichment analyses of genes that are highly correlated with tissue ratios suggest that the same tissue is associated with similar biological processes in different breast cancer subtypes, whereas each subtype also has its own idiosyncratic biological processes governing the development of these tissues. Taken all together, our approach can lead to new insights in exploring relationships between image-based phenotypes and their underlying genomic events and biological processes for all types of solid tumors.
