Objective To investigate the positive rates and susceptibility of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) in urogenital mycoplasma infection under three years.Methods Culture,identification and susceptibility test were performed on 4 414 specimens collected from suspected patients with mycoplasma infection by using Antu mycoplasma kits.Results In the 4 414 patients,2 295 cases with mycoplasma infection were detected and the positive rate was 51.99％.The infection rates of Uu and Mh respectively were 40.69％ and 2.08％,and the both infection rate was 9.22％.Antibiotic sensitive rates of josamycin(JOX),doxycycline(DOX),clarithromycin(CLA),gatifloxacin(GAT) and erythromycin(ERY) were 96.03％,95.51 ％,78.69 ％％,77.21 ％ and 72.55 ％.Drug resistant rates of roxithromycin(RXT),thiamphenicol (THI),clindamycin (CLI) and clarithromycin(CLA) were 16.90％,22.27％,41.96％ and 17.60％.Conclusion Uu is the predominant mycoplasma in urogenital tract infection in the study.DOX,JOS,GAT and ERY can be chosen as the fist line drugs for the treatment of urogenital tract infection.RXT,THI,CLI and CLA with high drug resistant rates are not recommended to be used.

Objective:This study aimed to provide some biomechanical references for the clinical use and improvement of Herbst appliance. Methods: The three-dimensional model of the ′Temporomandibular joint mandible Herbst appliance system′was set up by SUPER SAP software (version 9.3). On this model, the passive tensile in the masticatory muscles and ligaments were analyzed under various bit reconstruction designed according to specified advanced displacement and vertical bite opening. Results: When Herbst appliance drove the mandible forward, there was not any tensile in the medial, lateral pterygoid and the collateral ligament, while the temporalis, the deep paret of masseter, the stylomandibular ligament, and the sphenomandibular ligament were passively drawn. Under various bite reconstruction, the passive tensile in the medial temporalis, the posterior temporalis, the stylomandibular ligament and the sphenomandibular ligament increased with the amount of the advancement of the mandible; The passive tensilein the posterior temporalis and the deep part of masseter increased with the amount of vertical bite opening of the mandible. Conclusion: The StL, SpL, PT and AT played an important role in functional reconstruction of mandible by Herbst. All five group of bite reconstruction (3～7mm advancement, 4～2mm vertical bite opening of the mandible) designed by this study can be selected in clinic according to the patient′s capa- bility of adaptation, the extent of malocclusion and the potential and direction of growth.

Objective To explore the expression of HCCR, pERK and pELK1 in gastric cancer tissue and para-carci-noma tissue, and to explove its correlations. Methods In 60 human gastric cancers and their corresponding paraneo-plastic tissuses,the expression of HCCR, pERK and pELK1 were detected by immunohistochemistry. Results The ex-pression of HCCR was 75.0%(45/60), pERK, and pELK1 were 73.3%(44/60) and 71.7%(43/60), respectively, and the expression of proteins in gastric tumor were higher than that in paraneoplastic tissues (P<0.05). Conclusion The HCCR, pERK and pELK1 are higher expressed in tumor tissues, availably as a auxiliary index for clinical immunohis-tochemistry in gastric cancer.

OBJECTIVE: To perform prenatal diagnosis, pedigree analysis, and genetic counseling of a pregnant woman who gave birth to a child with Kleefstra syndrome. METHODS: Karyotype analysis, chromosomal microarray analysis (CMA), multiplex ligation-dependent probe amplification (MLPA) and fluorescence in situ hybridization (FISH) were used of peripheral blood and amniotic fluid to find causes. Recurrence risk assessment was performed later. RESULTS: The amniotic fluid sample showed a 9q34.3 microduplication of arr (hg19) 9q34.3 (140 168 806-141 020 389)× 3, which overlapped the 9q34.3 microdeletion region of proband. The pregnant woman was detected with a balanced translocation of ish, t(9;17)(9q34.3; qter) (9p+; 17p+,9q+, 17q+). No other abnormal results were found in the family. CONCLUSION Offspring who share the same chromosome segment deletion or duplication are always from parent who carries balanced chromosomal structural aberration.

Objective:Distribution and antibiotic resistance of pathogen isolated from children with intra-abdominal infection (IAI) associated sepsis in the intensive care unit (ICU) were analyzed to provide a reference for the empirical anti-infective treatment of IAI in children.Methods:We retrospectively analyzed the data of 116 children with culture-positive IAI-associated sepsis admitted to Children's Hospital of Zhejiang University School of Medicine from January 2019 to December 2021. Clinical isolation and drug resistance analysis were conducted based on different years of onset, locations of onset, and primary diseases.Results:A total of 186 strains of pathogens causing children with IAI-associated sepsis in ICU were collected. The distribution and antibiotic resistance of pathogen were as follows: the percentages of gram-positive bacteria, gram-negative bacteria, and fungi were 53.2%, 40.9%, and 5.9%, respectively; the top four strains were Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecalis, accounting for 57.0% of all isolates; Enterococcus faecium(19.9%) and Enterococcus faecalis (10.2%) were the dominating gram-positive bacteria; Escherichia coli (13.4%) and Klebsiella pneumoniae (13.4%) were more common gram-negative bacteria; Fungi were dominated by Candida albicans (3.8%).Fifty-seven strains of gram-positive bacteria were detected in 61 children with infectious diseases, mainly Enterococcus faecium (28 strains). There were 53 gram-negative strains, mainly Klebsiella pneumoniae (21 strains). Thirty-two strains of gram-positive bacteria were detected in 40 children with digestive tract malformation, and Enterococcus faecalis (six strains) were the most common. There were 14 gram-negative strains, mainly Escherichia coli (six strains). In 13 children with malignant tumors of digestive system, nine strains of gram-positive bacteria were cultured, and Enterococcus faecium (four strains) was the most common. There were eight gram-negative strains, mainly Escherichia coli (four strains).In the 46 community-acquired IAI patients,30 gram-positive isolates were cultured,mainly including Enterococcus faecium (12 strains), Staphylococcus epidermidis (seven strains), and Viridans streptococci (six strains); Forty gram-negative isolates mainly contained Escherichia coli (16 strains), Klebsiella pneumoniae (14 strains), and Enterobacter cloacae (five strains). In the 70 hospital-associated IAI patients, 69 gram-positive isolates such as Enterococcus faecium (25 strains), Enterococcus faecalis (17 strains), Enterococcus gallinarum (eight strains), and Staphylococcus aureus (seven strains) were cultured;Tirty-six gram-negative isolates were dominated by Klebsiella pneumoniae (11 strains), Escherichia coli (nine strains), Pseudomonas aeruginosa (four strains), and Acinetobacter baumannii (four strains). The mixed infection rate of clinical pathogens was up to 46.6%, and the overall resistance rate was 43.4%, in which gram-negative bacteria had high sensitivity to piperacillin/tazobactam, cefoperazone/sulbactam, imipenem, and tigecycline.The detection rates of Klebsiella pneumoniae and Escherichia coli producing extended-spectrum β-lactamases were 36.0% and 24.6%, respectively, with 100% sensitivity to tigecycline. Gram-positive bacteria showed 100% sensitivity to vancomycin, linezolid, and tigecycline. Conclusion:Pathogen isolated from children with IAI-associated sepsis in ICU were dominated by Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecalis,respectively. Before confirmation of pathogenic bacteria, antibacterial agents can be selected according to the infection type. It is important to note that a single broad-spectrum antibacterial agent or combination medication can be considered the initial empirical choice due to the large variety of pathogens, high rates of mixed infections, and high overall resistance.

Gegen Qinlian Decoction (GQD), a traditional Chinese medicine (TCM) formula, has long been used for the treatment of common metabolic diseases, including type 2 diabetes mellitus. However, the main limitation of its wider application is ingredient complexity of this formula. Thus, it is critically important to identify the major active ingredients of GQD and to illustrate mecha-nisms underlying its action. Here, we compared the effects of GQD and berberine, a hypothetical key active pharmaceutical ingredient of GQD, on a diabetic rat model by comprehensive analyses of gut microbiota, short-chain fatty acids, proinflammatory cytokines, and ileum transcriptomics. Our results show that berberine and GQD had similar effects on lowering blood glucose levels, modulating gut microbiota, inducing ileal gene expression, as well as relieving systemic and local inflammation. As expected, both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria, including Faecalibacterium and Roseburia, thereby attenuating intestinal inflammation and lowering glucose. Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with ber-berine or GQD. Moreover, concentration of serum proinflammatory cytokines and expression of immune-related genes, including Nfkb1, Stat1, and Ifnrg1, in pancreatic islets were significantly reduced after treatment. Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota. The strategy employed would facilitate further stan-dardization and widespread application of TCM in many diseases.

Based on the traditional Chinese medicine （TCM）'s understanding of consumptive thirst disease and modern medicine's understanding of the etiology of diabetes mellitus and the evolution of the disease， this article discussed the rationality and clinical significance of using "sugar collateral disease" as the name of diabetes mellitus in TCM， to provide a reference for modernization and development of TCM diseases' names. It is argued that the clinical manifestations described in the TCM disease name of consumptive thirst disease are only at a certain stage of diabetes mellitus， and it is difficult to cover the clinical characteristics of modern diabetes mellitus comprehensively. In 2003， academician TONG Xiaolin proposed to use "sugar collateral disease" as the TCM disease name of diabetes mellitus， which on the one hand can reflect the essence of diabetes mellitus， and on the other hand can embody the disease location， disease mechanism and the evolution of the disease， highlight the harms of complications， and serve as a warning for the early diagnosis and treatment of the disease， which can help to enhance the level of diagnosis and treatment of diabetes mellitus in TCM.

Objective: To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m², 10 mg/m² or 12 mg/m² as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) . Methods: A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m²) as induction chemotherapy in newly diagnosed patients of adult AML. Results: Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (P<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% CI) of IDA 10 mg/m² group and IDA 12 mg/m² group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m² group (P<0.001, P=0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (P=0.007) . Interestingly, IA regimen with IDA 10 mg/m² was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[OR=0.47 (95% CI 0.31-0.71) , P<0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (P=0.089) . However, the odds ratios (95% CI) of IDA 12 mg/m² when compared with the IDA 8 mg/m² was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×10⁹/L in IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (P=0.012) and of platelet count lower than 20×10⁹/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (P=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (P<0.001) . Conclusions For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m² is clinically superior to IDA 8 mg/m² and IDA 12 mg/m² in favorable intermediate AML subgroup. However, idarubicin 12 mg/m² is more suitable to adverse AML subgroup.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.
