Objective To evaluate the performance of a latex enhanced immunoturbidimetric?2-microglobulin kit in clinical use. Methods The lower limit of detection,precision,accuracy and linearity range was determined on the automatic chemistry analyzer Hitachi 7170S. Results The lower limit of detection was 0. 09mg/L. The within-run precision was less than 4% while the between-run precision was less than 8%. The accuracy was 99.29 % and the linearity range was 0.2～18mg/L. Conclusion The?2-microgiobulin kit shows good performance in clinical use.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy associated with poor prognosis.Increasing data regarding to alteration of gene expression signatures of oncogenes and tumor suppressors involved in the pathogenesis of T-ALL and the major mechanisms of T-cell transformation may contribute to define the biological markers for treatment response and prognosis,and has important clinical implications.In this review,advance knowledge concerning the characteristics of early T-cell precursor ALL,the alteration of TAL1 and NOTCH1 related genes and target inhibiton effects based on these alterations from 2012 the 54th ASH annual meeting ars summarized.

Objective To investigate the association between malnutrition parameters and serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level in male patients aged ≥ 80 years with normal ejection fraction.Methods A total of 197 elderly male patients aged 80 95 years (average 85.4±9.7) were enrolled.Each patient received echocardiograms following admission,and ejection fraction was calculated.Serum concentrations of NT-proBNP were measured by electrochemiluminescence immunoassay.Multiple Logistic regression analyses and receiver operating characteristic (ROC) curves were used to assess the association between malnutrition parameters and serum level of NT-proBNP.Results Serum NT-proBNP level was higher in patients with malnutrition than in the controls [(711.9±1063.3) ng/L vs.(1375.2-±1891.7) ng/L,P=0.006].Pearson correlation analysis showed that the malnutrition parameters such as body mass index (BMI),blood hemoglobin,albumin and pre-albumin were negatively correlated with serum NT proBNP level (all P＜0.05).Logistic regression analysis showed that BMI and serum pre albumin level were independently associated with serum NT-proBNP level elevation (P=0.028 and 0.006,respectively).ROC curve analysis showed that the malnutrition parameters could predict the serum NT-proBNP level elevation.The area under the ROC curves for BMI,levels of blood hemoglobin,albumin and prealbumin in predicting serum NT proBNP level elevation was 0.7 (P=0.002),0.7 (P=0.004),0.6 (P=0.036),0.6 P=0.002),the sensitivity was 75.5％,51.0％,38.8％,89.8％,and the specificity was 54.4％,70.2 ％,84.2％ and 31.6 ％,respectively.Conclusions The malnutrition parameters including BMI,blood hemoglobin,albumin and pre-albumin can predict serum NT-proBNP level elevation.BMI and serum pre-albumin level are independently associated with serum NT-proBNP level elevation in male patients aged ≥ 80 years with normal ejection fraction.

Objective To reconstruct the soft tissue defect in the back or neck after excision of hypertrophoc scar or giant nevus by using transmidline pre expanding scapula flap vascularied by ipsilateral circumflex scapular artery. Methods The reconstruction can be accomplished in two stage procedures. First, scapular flaps were expanded for 4 6 weeks prior to transfer in 8 patients. Second,the pedicled flaps were designed across the entire back to incorporate both scapular territories but were rotated on a single vascular pedicle. Results All flaps survived. Only two flaps had marginal necrosis, and the wound healed well by dressing. Conclusion Flap expansion produces a delay that augments blood supply and increases the area of skin that survives on a single vascular pedicle. This technique may be useful in selected patients in whom a large and thin fasciocutaneous flap is required and there is sufficient time to allow flap expansion prior to thansfer. It is easy to harvest, and donor site morbidity is negligible. The patients can get better functions and quality of life.

Abstract： Objective　To investigate the epidemiological and molecular characteristics of carbapenem-resistant Klebsiella pneumoniae isolated from blood cultures of patients with bloodstream infections in Shanxi Bethune Hospital from January 2015 to January 2022. Methods　Klebsiella pneumoniae strains isolated from blood cultures of patients with bloodstream infections at Shanxi Bethune Hospital from January 2015 to January 2022 were collected for the study. Bacterial identification, drug sensitivity testing, and an improved carbapenem inactivation test were conducted to screen for carbapenem-resistant Klebsiella pneumoniae. Next-generation sequencing was performed on all strains, while whole genome sequencing was carried out on two strains that tested positive for the modified Hodge test indicating resistance to carbapenems. Results　A total of 431 strains of Klebsiella pneumoniae were isolated from blood cultures of patients with bloodstream infections at Shanxi Bethune Hospital between January 2015 to January 2022, among which 33 were carbapenem-resistant strains including 11 highly virulent ones and 2 of these exhibited positive for the modified Hodge test. All strains were resistant to both ertapenem and imipenem, with only one strain being intermediate-resistant to meropenem. Among the 33 resistant strains, KPC-2 was detected in 26 strains and NDM-1 in 4; three strains possessed dual carbapenemase types (KPC-2/NDM-9, KPC-2/OXA-1, NDM-1/OXA-1), while four did not show any detectable carbapenem-resistance genes. Evolutionary analysis following next-generation sequencing revealed that the main sequence types (ST) among these isolates were ST11, ST147, and ST412; and the predominant serotypes were KL64, KL47, and KL25. The plasmid conjugal transfer experiments were successful in 18 strains. The two high virulence strains identified in the modified Hodge test were found to carry virulence and resistance plasmids upon whole genome sequencing. Conclusions　The detection of carbapenem-resistant Klebsiella pneumoniae in patients with bloodstream infections has been increasing annually since 2015, with an outbreak occurring in 2021. The carbapenemase KPC-2 gene was the most prevalent, with the majority of strains being of the ST11/KL64 type. Strengthening screening and control measures for clinical drug-resistant strains is crucial for effective anti-infective treatment.

Recently a number of acupuncture clinical trial projects mainly conducted by conventional scientists have generated many negative results. A large meta-analysis of patient-level acupuncture data for the treatment of chronic pain conditions have demonstrated that the effects of verum acupuncture on pain improvement have statistically significant, but small, differences compared with sham-acupuncture procedures and no difference between acupuncture points and non-points. These conclusions have puzzled the acupuncture community and made confusion for acupuncture research and practices. The purpose of this paper was to compare differences between acupuncture clinical practices and the trial studies, which include "acupuncture technical principles", "acupuncture clinical trial design", and "acupuncture practice based on the theory of traditional Chinese medicine". These factors contribute to the puzzle between the acupuncture community/practice and acupuncture clinical trials, which can be improved in future studies.
