Chinese Acupuncture & Moxibustion 2009;29(5):379-381
In this paper, the basic concept of biofeedback therapy and the relationship between getting qi in acupuncture and biofeedback are introduced. Getting qi in acupuncture as a controllable index of biological information feedback between the physician and the patient, meets the requirement of technique manipulation for biofeedback therapy. Arrival of qi has double regulative effects on the psychological and physiological functions of the patient, and has the effectiveness of the language suggestion and behavior suggestion in correcting the error in cognition of the patient. To take getting qi as an index in treatment of mental disorders conforms to theories of traditional Chinese medicine and is supported by modern medical research achievements, enriching contents and ways of biofeedback therapy and facilitating the development of acupuncture medicine towards biological-psychological-social medicine model.

BACKGROUNDSedation for the coblation-assisted upper airway procedure has lacked easy modulation between appropriate pain control and airway protection. This study aimed to compare the effectiveness of dexmedetomidine versus target controlled propofol infusion in providing sedation during a coblation-assisted upper airway procedure.
METHODSIn a prospective, randomized trial, 60 adult patients with obstructive sleep apnea syndrome due to undergoing a coblation-assisted upper airway procedure were enrolled and randomly allocated to receive dexmedetomidine, 1.0 µg/kg over 10 minutes and maintain dosage 0.7 µg×kg(-1)×h(-1) (n=30) or propofol target controlled infusion (n=30). Satisfaction with the analgesia and tolerance of the procedure by the patient, as assessed by a visual analogue scale, were evaluated as primary outcomes. Cardiopulmonary parameters and some side effects were monitored and recorded.
RESULTSBoth groups of 30 patients had comparable demographics and initial parameters. Patients in the propofol group reported more pain (P<0.05), tolerated the procedure less well (P<0.05), and were less satisfied with the different stages of procedure (P<0.05 or P<0.01). Changes in mean arterial pressure and heart rate were more dramatic in the propofol group (P<0.05). The dexmedetomidine group experienced fewer airway events and less respiratory depression than did the propofol group.
CONCLUSIONDexmedetomidine in conjunction with local anesthesia offered better analgesia and conscious sedation for a coblation-assisted upper airway procedure as well as less airway obstruction, apnea and greater haemodynamic stability.

OBJECTIVETo evaluate the feasibility and efficiency of extracorporeal cardiac shock wave therapy (CSWT) for treatment of coronary artery disease.
METHODSTwenty-five patients with 1 - 16 years history of chronic angina pectoris underwent the CSWT. Before and after the treatment, low-dose Dobutamine stress echocardiography and (99)Tc(m)-MIBI myocardial perfusion SPECT were applied to locate the ischemic segments, detect the viable myocardium and evaluate the effect of CSWT. Under the guidance of echocardiography, CSWT was applied in R-wave-triggered manner with low energy (0.09 mJ/mm(2)) at 200 shoots/spot for 9 spots (-1-0-+1 combination). Patients were divided group A and group B. Sixteen patients in group A were applied 9 sessions on 29 segments within 3 month and nine patients in group B were applied 9 sessions on 13 segments within 1 month. Ten chronic angina pectoris patients receiving standard medication served as controls.
RESULTSAll patients completed the 9 sessions without procedural complications or adverse effects. CSWT significantly improved symptoms as evaluated by NYHA, Canadian Cardiovascular Society (CCS) class sores, Seattle angina questionnaire (SAQ), 6-min walk and the use of nitroglycerin (P < 0.05). CSWT also improved myocardial perfusion and regional myocardium function as evaluated by rest SPECT and stress peak systolic strain rate (PSSR) (P < 0.01). Myocardial perfusion improvement was more significant in group A compared with group B (1.21 ± 0.86 vs. 0.83 ± 0.80, P < 0.01). All parameters remained unchanged in control group during follow up.
CONCLUSIONThese preliminary results indicate that CSWT is safe and effective on ameliorating anginal symptoms for chronic angina pectoris patients.

BACKGROUNDAcute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide. However, epidemiologic data concerning AKI in China are still lacking. The objectives of this study were to characterize AKI defined by RIFLE criteria, assess the association with hospital mortality, and evaluate the impact of AKI in the context of other risk factors.
METHODSThis prospective multicenter observational study enrolled 3,063 consecutive patients from 1 July 2009 to 31 August 2009 in 22 ICUs across mainland China. We excluded patients who were admitted for less than 24 hours (n = 1623), younger than 18 years (n = 127), receiving chronic hemodialysis (n = 29), receiving renal transplantation (n = 1) and unknown reasons (n = 28). There were 1255 patients in the final analysis. AKI was diagnosed and classified according to RIFLE criteria.
RESULTSThere were 396 patients (31.6%) who had AKI, with RIFLE maximum class R, I, and F in 126 (10.0%), 91 (7.3%), and 179 (14.3%) patients, respectively. Renal function deteriorated in 206 patients (16.4%). In comparison with non AKI patients, patients in the risk class on ICU admission were more likely to progress to the injury class (odds ratio (OR) 3.564, 95% confidence interval (CI) 1.706 - 7.443, P = 0.001], while patients in the risk class (OR 5.215, 95% CI 2.798-9.719, P < 0.001) and injury class (OR 13.316, 95% CI 7.507-23.622, P < 0.001) had a significantly higher probability of deteriorating into failure class. The adjusted hazard ratios for 90-day mortality were 1.884 for the risk group, 3.401 for the injury group, and 5.306 for the failure group.
CONCLUSIONSThe prevalence of AKI was high among critically ill patients in Chinese ICUs. In comparison with non-AKI patients, patients with RIFLE class R or class I on ICU admission were more susceptibility to progression to class I or class F. The RIFLE criteria were robust and correlated well with clinical deterioration and mortality.

OBJECTIVE:
To observe the effect of electroacupuncture (EA) preconditioning on the expressions of tyrosine kinase Lyn and spleen tyrosine kinase (Syk) in mast cells of subcutaneous loose connective tissue in the rats with urticaria and explore the potential biological mechanism of EA in the intervention of urticaria.
METHODS:
A total of 32 SD rats were randomized into a blank group, a model group, an EA group and a positive medication group, 8 rats in each one. Except of the blank group, the passive cutaneous anaphylaxis (PCA) was adopted to prepare the model of urticaria in the rats of the rest three groups. In the EA group, EA was applied to bilateral "Quchi" (LI 11), "Xuehai" (SP 10) and "Zusanli" (ST 36), with disperse-dense wave, 2 Hz/15 Hz in frequency and 1 mA in current intensity, once daily, for 20 min each time, consecutively for 7 days. In the positive medication group, loratadine (1 mg•kg•d) was for intragastric administration, once daily, consecutively for 7 days. The samples were collected for index detection 30 min after PCA antigen challenge in the rats of each group. Spectrophotometer was adopted to determine the effusion quantity of Evans blue in the allergized site of skin. HE staining was used to observe the morphological changes in the allergized site of skin. Toluidine blue staining was provided to observe mast cell degranulation in subcutaneous loose connective tissue in the allergized site of skin. Immunohistochemistry was applied to determine the protein expressions of Lyn and Syk during degranulation of mast cells.
RESULTS:
In the rats of the odel group, the eipdermis of allergized site was thickening, cells were disorganized in hierarchy and inflammatory cells were infiltrated largely in the dermis. In the positive medication group and the EA group, the epidermis was getting thin, cell arrangement was clear and the inflammatory cell infiltration was obviously alleviated as compared with the model group. Compared with the blank group, the OD value of skin dye effusion quantity, the degranulation rate of mast cells and the positive expressions of Lyn and Syk were all increased in the model group (<0.01). Compared with the model group, the OD value of skin dye effusion quantity, the degranulation rate of mast cells and the positive expressions of Lyn and Syk were all reduced in the EA group and the positive medication group (<0.01). Compared with the positive medication group, the degranulation rate of mast cells was increased significantly in the EA group (<0.01).
CONCLUSION
Electroacupuncture at "Quchi" (LI 11), "Xuehai" (SP 10) and "Zusanli" (ST 36) reduces vascular permeability and gives play to the role of anti-allergy by the way of regulating and controlling the degranulation of mast cells in the rats with urticaria and the effect mechanism of electroacupuncture may be related to the inhibition of protein expressions of Lyn and Syk in mast cells.

Objective Based on the techniques of continual tissue slices, the human epididymis was rebuilt for understanding the anatomical and histological features of the epididymal ducts. Methods Continuous tissue slices of one human epididymis were performed and digital slice images were obtained through scanning with Leica-Aperio AT2; the pipe wall of epididymal duct was aligned in sequence with Photoshop CC 2018 software and VGStudio MAX V3.0 software was used for three-dimensional synthesis. Finally, the later modification was carried out with Materialise Magics V22.0 software. Another human epididymis was used for electron microscopy. The histological features of epididymal ducts were analysed by combining slices and three-dimensional reconstruction. Results A total of 4331 and 543 slices in transverse and sagittal section respectively were prepared with a thickness of 7 |ira. According to the three-dimensional structure, regional distribution of human epididymal duct could be found obviously and the caput, corpus and cauda of epididymis could be clearly divided into 7, 9 and 4 subregions respectively. There were tissue intervals among adjacent subregions and epididymal ducts were disordered within each subregion, but differences were existed in tubular diameter and epithelial structure, and adjacent subregions were connected by single epididymal duct in the corpus and cauda. Conclusion The human epididymal duct can be successfully reconstructed by continual tissue slices technique. The human epididymal duct has regional distribution in space obviously and there are differences between different subregions.

Objective: To screen and analyze the mutations of MITF gene in two children of type Ⅱ Waardenburg syndrome (WS2) from different families in Yunnan,China,and to explore the possible molecular pathogenesis. Methods: With informed consent, medical history collection, physical examinations, audiological evaluation, and high resolution computer tomography (HRCT) scan of temporal bone were performed on the two WS2 probands and their family members. Genomic DNA was extracted from peripheral blood of all individuals. The coding regions including all exons, part of introns and promoters of MITF, PAX3, SOX10, SNAI2, END3, ENDRB, and KITLG genes were sequenced by high-throughput sequencing. According to the results of high-throughput sequencing, pathogenic mutations detected in the probands and their parents were verified by Sanger sequencing. Results: The proband 1 carried c.641_643delGAA mutation in the 7th exon of MITF gene, which was a frame-shift mutation resulting in an amino acid change of p.214delR. It was a de novo mutation as the parents of proband 1 showed no variation on this site. The proband 2 carried heterozygous loss of the large fragment ranging from exon 1 to exon 9 of MITF gene, which defected the function of MITF protein. Conclusion: Genetic examinations provide important evidence for diagnosis of Waardenburg syndrome. Heterozygous mutation c.641_643delGAA and heterozygous loss of the large fragment ranging from exon 1 to exon 9 of MITF gene might be the molecular pathogenesis of the two WS2 probands in this study.

OBJECTIVE:
To investigate the effects of matrine on antigen presentation of dendritic cells (DCs), and to explore the pharmacological mechanism of matrine on anti-tumor effect.
METHODS:
Different concentrations (0, 1, 2, 4, 8 and 16 µ g/mL) of matrine were co-cultured with DCs, the harvested DCs were co-cultured with antigens of Lewis lung cancer (LLC) cells, and then DCs and T cells were co-cultured to produce DCs-activated killer (DAK) cells, which have significant tumor-killing activity. The expression of cytokines, mRNA and protein of toll-like receptors (TLRs) in DCs were detected by enzyme linked immunosobent assay, polymerase chain reaction and Western blot, respectively. And the killing effect of DAK were measured by MTT assay.
RESULTS:
Matrine significantly increased the mRNA expression of TLR7, TLR8, myeloid differentiation factor 88 (MyD88), tumor necrosis factor receptor-associated factor 6 (TRAF-6) and I κ B kinase (IKK), as well as the protein expression of TLR7 and TLR8, and up-regulated the levels of interleukin-12 (IL-12), IL-6 and tumor necrosis factor-α (TNF-α), meanwhile, it also increased the expressions of MHC-II, CD54, CD80 and CD86 in DCs. DCs-activated effector T cells had significant tumor-killing activity. When the concentration of matrine was more than 4 µg/mL, all indices had significant difference (P<0.01 or P<0.05).
CONCLUSION
Matrine plays an anti-tumor role by regulating TLRs signal transduction pathway, promoting the secretion of inflammatory cytokines and enhancing immune function.

OBJECTIVE:
To evaluate the performance of 3.0T magnetic resonance imaging examination (MRI) for the local detecting of muscle invasive bladder cancer following transurethral resection of bladder tumor (TURBT).
METHODS:
Retrospective study identified 55 patients with pathology-proven bladder cancer who underwent transurethral resection of bladder tumor followed by 3.0T magnetic resonance imaging between September 2012 and April 2019 in our hospital. Two radiologists reviewed pelvic magnetic resonance imaging together and judged muscle invasive bladder cancer. Sensitivity, specificity and accuracy were calculated for the presence of muscle invasion by T2 weighted imaging (T2WI) only, diffusion-weighted imaging (DWI) only and T2WI+DWI compared with the findings at radical cystectomy as the reference standard.
RESULTS:
Of the 55 patients with pathological results from radical cystectomy, 3.64% (2/55) had no residual disease; 29.09% (16/55) were non-muscle invasive bladder cancer on pathology, including 13 cases in T1 and 3 cases in Ta; 34.55% (19/55) were in stage T2 depending on pathology, 25.45% (14/55) in T3, and 7.27% (4/55) in T4. The average age was 60.76 years, ranging from 42 to 82 years. There were 48 males and 7 females in our study. Before pelvic MRI examination, all the patients received transurethral resection of bladder tumor, including 16 cases taking the operation in our hospital and 39 cases in other hospitals. The interval between the pelvic MRI examination and transurethral resection of bladder tumor was more than 2 weeks in all the patients. They all underwent radical cystectomy within 1 month after the pelvic MRI examination, and no patient underwent radiotherapy or chemotherapy in our study during the interval between the MRI examination and radical cystectomy. T2WI only, DWI only, and T2WI+DWI of 3.0T magnetic resonance imaging for readers were with sensitivity: 94.59%, 83.78%, 91.89%; with specificity: 66.67%, 77.78%, 72.22% and with accuracy: 85.45%, 81.82%, 85.45%, respectively.
CONCLUSION
3.0T MRI may have a role in diagnosing muscle invasive bladder cancer following TURBT. T2WI has the advantage of detecting the location of bladder tumor, and DWI has the advantage of differentiating between the benign and malignant lesion. 3.0T MRI T2WI+DWI has a good utility in the detection of muscle invasive bladder cancer following TURBT with satisfied accuracy.

BACKGROUNDUrine output (UO) is an essential criterion of the Kidney Disease Improving Global Outcomes (KDIGO) definition and classification system for acute kidney injury (AKI), of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria (KDIGOUO) could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria (KDIGOSCr).
METHODSWe conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a 2-month prospective cohort study (July 1, 2009 to August 31, 2009) involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China. AKI was diagnosed and classified separately based on KDIGOUOand KDIGOSCr. Hospital mortality of patients with more severe AKI classification based on KDIGOUOwas compared with other patients by univariate and multivariate regression analyses.
RESULTSThe prevalence of AKI increased from 52.4% based on KDIGOSCrto 55.4% based on KDIGOSCrcombined with KDIGOUO. KDIGOUOalso resulted in an upgrade of AKI classification in 7.3% of patients, representing those with more severe AKI classification based on KDIGOUO. Compared with non-AKI patients or those with maximum AKI classification by KDIGOSCr, those with maximum AKI classification by KDIGOUOhad a significantly higher hospital mortality of 58.4% (odds ratio [OR]: 7.580, 95% confidence interval [CI]: 4.141-13.873, P< 0.001). In a multivariate logistic regression analysis, AKI based on KDIGOUO (OR: 2.891, 95% CI: 1.964-4.254, P< 0.001), but not based on KDIGOSCr (OR: 1.322, 95% CI: 0.902-1.939, P = 0.152), was an independent risk factor for hospital mortality.
CONCLUSIONUO was a criterion with additional value beyond creatinine criterion for AKI diagnosis and classification, which can help identify a group of patients with high risk of death.
