There is a rare case of an elderly diabetic with diabetic foot infection at Hainan General Hospital in September 2021, which was diagnosed as Corynebacterium diphtheriae infection incidentally on routine culture with conventional methods and molecular biological approaches, to aid in diagnosis in clinical practice. Owing to smear staining, Albert staining and VITEK 2 system, automated identification systems viz matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) confirmed combing with 16S ribosomal RNA (16S rRNA) gene has been used for the taxonomic classification of bacteria. Otherwise, toxin gene tox was done for diphtheria toxin synthesis. The isolate was Gram-stain-positive, rod-like arrangement with irregular thickness, with characteristic metachromatic granules, ferment most sugars and homology of 16S rRNA analyses with C. diphtheriae NCTC11397T (MW682323.1) was greater than a 100% possibility, toxin gene tox was negative. The findings lay the foundation to clinical identify and trace of non-toxigenic C. diphtheriae. Moreover, this work provides insights into the non-toxigenic C.diphtheriae that contribute to recognized risk of non-toxigenic C.diphtheriae infections.

In the era of artificial intelligence based on big data, data acquisition, storage and processing are more convenient, which provides a guarantee for accelerating the development of traditional Chinese medicine (TCM), but it has not yet achieved organic integration with TCM theory. Based on preliminary research on the supramolecular "Qi chromatography" theory of TCM, combined with the current development trend of artificial intelligence, this paper analyzed the biological intelligence attribute of the function of TCM supramolecular "imprinting template", in order to provide reference for the development of TCM drug innovation. Both the human body and Chinese materia medica are giant complex supramolecular bodies evolved from natural organisms. According to the "imprinting template", the "social molecules" are controlled step by step to form the meridians and viscera. The interaction produces the original theory of TCM, in which the self-recognition, self-assembly, self-organization and self-replication of the "imprinting template" reflect the "intelligence" function attributes:the human body uses the "imprinting template" to self-identify and sense the ingredients of TCM, and store the memory information database in the meridian and collateral organs in the form of "imprinting template", and then pass the "imprinting template". The comparison, analysis, and judgment of imprinting templates guide the self-assembly, self-organization and self-replication among "molecular society", synthesize biological machines, produce biological functions, repair or strengthen biological supramolecular bodies, and present the most basic "intelligence" attribute. This suggests that the theory of theory-method-prescription-medicine of TCM is the weak embodiment of biological "intelligence", while the human brain function is the strong embodiment of biological "intelligence". Since the intelligent function of supramolecular "imprinting template" runs through the natural world, artificial intelligence that can characterize the strong "intelligence" form of the human brain will also be integrated into all aspects of the natural world, suggesting the development direction of "intelligence" functionalization of drug innovation mode.

Accurate methods for identifying pelvic lymph node metastasis (LNM) of prostate cancer (PCa) prior to surgery are still lacking. We aimed to investigate the predictive value of peripheral monocyte count (PMC) for LNM of PCa in this study. Two hundred and ninety-eight patients from three centers were divided into a training set (n = 125) and a validation set (n = 173). In the training set, the independent predictors of LNM were analyzed using univariate and multivariate logistic regression analyses, and the optimal cutoff value was calculated by the receiver operating characteristic (ROC) curve. The sensitivity and specificity of the optimal cutoff were authenticated in the validation cohort. Finally, a nomogram based on the PMC was constructed for predicting LNM. Multivariate analyses of the training cohort demonstrated that clinical T stage, preoperative Gleason score, and PMC were independent risk factors for LNM. The subsequent ROC analysis showed that the optimal cutoff value of PMC for diagnosing LNM was 0.405 × 109 l

BACKGROUND:
Generic drugs are bioequivalent to their brand-name counterparts; however, concerns still exist regarding the effectiveness and safety of generic drugs because of small sample sizes and short follow-up time in most studies. The purpose of this study was to evaluate the long-term antihypertensive efficacy, cost-effectiveness and cardiovascular outcomes of generic drugs compared with brand-name drugs.
METHODS:
In a multicenter, community-based study including 7955 hypertensive patients who were prospectively followed up for an average of 2.5 years, we used the propensity-score-matching method to match the patients using brand-name drugs to those using generic drugs in a ratio of 1:2, 2176 patients using brand-name drugs and 4352 patients using generic drugs.
RESULTS:
There were no significant differences between generic drugs and brand-name drugs in blood pressure (BP)-lowering efficacy, BP control rate, and cardiovascular outcomes including coronary heart disease and stroke. The adjusted mean (95% confidence interval [CI]) of systolic BP (SBP)-lowering was -7.9 mmHg (95% CI, -9.9 to -5.9) in the brand-name drug group and -7.1 mmHg (95% CI, -9.1 to -5.1) in the generic drug group after adjusting for age, sex, body mass index, number of antihypertensive drugs and traditionally cardiovascular risk factors. Among patients aged <60 years, brand-name drugs had a higher BP control rate (47% vs. 41%; P = 0.02) and a greater effect in lowering SBP compared with generic drugs, with the between-group difference of 1.5 mmHg (95% CI, 0.2-2.8; P = 0.03). BP control rate was higher in male patients using brand-name drugs compared with those using generic drugs (46% vs. 40%; P = 0.01). Generic drugs treatment yielded an average annual incremental cost-effectiveness ratio of $315.4 per patient per mmHg decrease in SBP compared with brand-name drugs treatment.
CONCLUSIONS
Our data suggested that generic drugs are suitable and cost-effective in improving hypertension management and facilitating public health benefits, especially in low- and middle-income areas.

OBJECTIVE:
To explore the characteristics of cytogenetics and molecular genetics in patients with multiple myeloma(MM).
METHODS:
Fluorescence in situ hybridization(FISH) was used for molecular genetics analysis in 86 cases of newly diagnosed MM, at the same time the chromosome karyotype analysis was performed in 20 cases. Specimen were bone marrow cells.
RESULTS:
FISH detection showed that 68 cases of MM (79.07%) had at least one type of the molecular genetic abnormalities. The positive rates of IgH rearrangement, 1q21 amplification, D13S319 deletion, RB1 deletion and.P53 deletion were 62.79%, 26.74%, 24.42% ,13.95% and 1.16%, respectively. The positive rate of IgH was significantly higher than that of any other probes(P<0.01). The positive rate of IgH was 79.41% in 68 cases. Out of which the positive rate of IgH single and combined with 1, 2, 3, 4 probes was 59.26%, 24.07%, 11.11%, 5.56% and 0 respectively. The positive rate of IgH only was very signficantly higher than that of combined with any other probes(P<0.01).The positive rate of 1q21 was 33.82% in 68 cases, Out of which the positive rates of 1q21 or combined with 1,2,3,4 probes was 21.74%, 43.48%, 21.74%,13.04% and 0 respectively, the 1q21 probe showed positive as combined with other probes(P<0.01), especially with IgH(P<0.05). The positive rates of D13S319 were 30.88% in 68 cases of patients, out of which the positive rates of D13S319 single or combined with 1, 2, 3, 4 probes was 14.29%, 28.57%, 42.86%, 14.29% and 0 respectively, the D13S319 combined with other probes appeared more significant positive(P<0.01), especially with 1 or 2 probes (P< 0.01). The positive rate of RB1 was 17.65% in 68 cases, the positive rate of RB1 singl or combined with 1, 2, 3, 4 probes were 0, 25%, 50%, 25% and 0, the RB1 appeared positive always combined with other probes, especially with D13S319 probe (P<0.01). The positive rate of P53 was 1.47%, as combined with RB1 and D13S319 probes. The chromosomal karyotyping showed that 3 cases carried abnormal chromosomal and 17 cases carried normal chromosome, Out of which 17 cases showed positive by FISH. There was a significant difference of sensitivity between FISH combined with chromosome karvotyping and single chromosome karvotype (P< 0.01).
CONCLUSION
The genetic abnormalies display obvious heterogenicity in MM. The sensitivity of FISH is higher than that of chromosomal karvotyping. If FISH and chromosome karvotyping are combined, the positive rate of abnormality can be raised.
