Objective:To study the clinical characteristics of congenital esophageal atresia (CEA) and risk factors of mortality associated with esophageal repair (ER) surgery.Methods:From January 2010 to December 2022, patients diagnosed of CEA using chest and abdomen X-ray and esophagography in our hospital were retrospectively reviewed. The patients were assigned into ER group and non-ER group according to the treatments. The ER group was subgrouped into survival group and death group according to the prognosis. Clinical data and outcomes were collected and compared between the groups.Results:A total of 553 cases were enrolled. According to Gross classification, 29 patients (5.2%) were type A, 2 patients (0.4%) were type B, 504 patients (91.1%) were type C, 6 patients (1.1%) were type D and 11 patients (2.0%) were type E. One patient had simple transluminal septal atresia of the esophagus. 406 patients were in ER group and 147 in non-ER group. Compared with ER group, non-ER group had significantly higher incidences of preterm birth, low birth weight and overall malformations (all P<0.05). In ER group, 152 patients (37.4%) received open thoracic surgery (OTS), 243 (59.9%) had video-assisted thoracoscopic surgery (VATS) and 11 (2.7%) were VATS converted to OTS. Postoperative anastomotic leakage (PAL) occurred in 92 patients (22.7%) and 15 patients (3.7%) died after surgery. The median length of hospital stay was 23 (17, 36) d. Compared with the survival group, the death group had higher incidences of preterm birth, low birth weight, VATS converted to OTS, mechanical ventilation after ER, and shorter length of hospital stay (all P<0.05). After adjusted for birth weight, VATS converted to OTS ( OR=9.585, 95% CI 1.899-48.374) and mechanical ventilation after ER ( OR=7.821, 95% CI 1.002-61.057) were risk factors of mortality in ER patients. Conclusions:Non-ER patients have higher incidences of preterm birth, low birth weight and overall malformations than ER patients. VATS is the method of choice for CEA. Preterm birth, low birth weight, VATS converted to OTS and mechanical ventilation after ER are risk factors of mortality in ER patients.

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Obstructive sleep apnea syndrome (OSAS) is a common clinical disease with high incidence and low treating proportion, difficult evaluation, and complicated nosogenesis. OSAS can cause systematic impairments. Various treatment methods were applied in clinical setting with the tendency of cross-disciplinary promotion. Oral treatment plays an exceedingly important role in OSAS research and therapy. This study reports the oral treatment involving OSAS therapy.

OBJECTIVETo evaluate the sensitivity and specificity of CD8CD28/CD8CD28T lymphocyte balance in predicting the gastrointestinal hemorrhage (GH) in patients with inflammatory bowel disease (IBD).

METHODSForty-nine IBD patients, including 30 with ulcerous colitis (UC) and 19 with Crohn's disease (CD), were enrolled to test peripheral blood CD8CD28and CD8CD28T cells using flow cytometry. All the patients were followed up for one year. The receiver-operating characteristic (ROC) curves were used to test the efficiency of CD8CD28/CD8CD28T lymphocyte balance to predict GH. The differences in lasting time of remission (LTR) under different factors were compared using Kaplan-Meier survival analysis, and the correlation between CD8T lymphocytes and the factors were analyzed.

RESULTSThe utilization rates of immunosuppressant, steroids, and biological agent (BA) were significantly higher in CD patients than in UC patients (P=0.003, 0.043 and 0.002, respectively). The frequencies of CD8CD28T cells were obviously higher in UC patients than those in CD patients (t=3.022, P=0.004). CD8CD28T cells, CD8CD28T cells, and especially CD8CD28/CD8CD28ratio (area under curve of 0.977, P=0.000; cut-off value of 1.14 [13.95%/12.24%] with a sensitivity of 93.3% and a specificity of 91.2%) showed good efficiencies in predicting GH (P<0.01). The mean and median of LTR of IBD patients who did not receive BA or surgical treatment were significantly longer (Χ=9.730, P=0.002; Χ=15.981, P=0.000). CD8CD28/CD8CD28ratio was significantly related to both BA (P=0.009) and surgery (P=0.038).

CONCLUSIONBoth decreased CD8CD28T cells and elevated CD8CD28T cells are closely correlated with GH, and their ratio can predict the occurrence of GH with a high sensitivity and specificity and is correlated with BA and surgery at the cut-off value of 1.14.

OBJECTIVETo characterize the pharmacokinetics and distribution profiles of deltamethrin in miniature pig tissues by gas chromatography-mass spectrometry (GC-MS).

METHODSPharmacokinetics and distribution of deltamethrin in blood and tissues of 30 miniature pigs were studied by GC-MS after oral administration of deltamethrin (5 mg/kg bw). Data were processed by 3P97 software.

RESULTSThe serum deltamethrin level was significantly lower in tissues than in blood of miniature pigs. The AUC0-72 h, Cmax, of deltamethrin were 555.330 ± 316.987 ng h/mL and 17.861 ± 11.129 ng/mL, respectively. The Tmax, of deltamethrin was 6.004 ± 3.131 h.

CONCLUSIONThe metabolism of deltamethrin in miniature pigs is fit for a one-compartment model with a weighting function of 1/C2. Deltamethrin is rapidly hydrolyzed and accumulated in miniature pig tissues.

Doctor WANG Zhi-zhong in the Southern Song Dynasty proposed the acupoint view of "location of disease", which explained the connotation of acupoints from the angle of clinic. Its meaning included two levels, one level meant pathological change on the body surface, that was the location of acupuncture diagnosis-treatment, and the other one indicated that the body surface which was the reflecting point of pathological change on the distal area or inside the body was the location of acupuncture diagnosis-treatment. The specific connotations of clinical acupoints were: location of pathogenic factors or reflection of pathogenic factors, regularity between acupoints un- der disease and specific organ, morphological differences and positioning variability after acupoints under disease, and acupoints examination, diagnosis and treatment.

OBJECTIVETo assess a multi-center study effectiveness of clinical pathways based on integrative medicine (IM) for chronic heart failure (CHF) patients.

METHODSA combined method of historical control study and clinical study on concurrent control was used. After the standard management for clinical pathways was carried out in four hospitals at home, the effects on hospitalization days, medical expenses, clinical efficacy, patient satisfaction, and quality of life were assessed.

RESULTSResults of non-concurrent historical control study showed that: the hospital stay was significantly shorter in the pathways group than in the retrospective group (12.59 days vs 18.44 days), and the total cost of hospitalization was significantly reduced in the pathways group (yen 9 051.90 vs yen 11 978.40), showing statistical difference (P < 0.01). Moreover, the effect on the heart function was better in the pathways group than in the retrospective group (the markedly effective rate: 45.60% vs 21.90%; the total effective rate: 96.80% vs 86.10%), showing statistical difference (P < 0.01). Results of clinical study on concurrent control showed that the hospital stay was significantly shorter in the pathways group than in the control group (11.19 days vs 13.21 days), showing statistical difference (P < 0.05). The average total cost of hospitalization was significantly lower in the pathways group than in the control group (yen 8 656.80 vs yen 11 609.70), showing statistical difference (P < 0.01). As for clinical efficacy of Chinese medical syndrome, the total effective rate was higher in the pathways group than in the control group (97.10% vs 93.62%), showing statistical difference (P < 0.05). The markedly effective rate of heart function was better in the pathways group than in the control group, showing statistical difference (49.30% vs 38.30%, P < 0.05). The overall satisfaction was higher in the pathways group than in the conventional group (P < 0.01). There was no statistical difference in the mortality within 3 months after discharge from hospital, and the readmission rate due to heart failure between the two groups (P > 0.05). But there was statistical difference in the quality of life (P < 0.05).

CONCLUSIONThe pathway could shorten the hospitalization time, decrease the cost of hospitalization, improve the clinical efficacy, improve patients' quality of life and satisfaction, therefore, it could be spread nationwide.

BACKGROUNDChromosomal abnormalities have been shown to play an important prognostic role in multiple myeloma (MM). Interphase fluorescence in situ hybridization (i-FISH) has been much more effective to identify cytogenetic aberrations in MM than conventional cytogenetic technique (CC). To clearly determine the cytogenetic features of Chinese MM patients and identify their prognostic implications, we designed a multicenter study based on i-FISH including 672 patients from 52 hospitals in China.

METHODSAll 672 patients were systematically screened for the following genomic aberrations: del(13q), IgH rearrangement, del(p53) and 1q21 amplifications.

RESULTSThe analysis showed that the chromosomal changes were detected in 22.1% patients by CC and in 82.3% patients by i-FISH. The most common abnormalities by CC were chromosome 1 aberrations (48.4%), -13/13q- (37.6%), hyperdiploidy (36.6%), hypodiploidy (30.1%) and IgH rearrangements (23.7%). The most frequent abnormalities by FISH was del(13q), which was found in 60.4% patients, whereas IgH rearrangement, 1q21 amplification and p53 deletions were detected in 57.6%, 49.0% and 34.7% cases, respectively. By statistical analysis, -13/13q- by CC was associated with low level of platelet (P = 0.015), hyperdiploidy was associated with low level of serum albumin (P = 0.028), and IgH rearrangement by FISH was associated with high level of β2 microglobulin (P = 0.019). Moreover, 1q21 amplification and del(p53) by FISH conferred a high incidence of progressive disease (PD) after initial therapy. Metaphase detection of IgH rearrangements and chromosome 1 aberrations concurrently was associated with a short progression free survival (PFS) (P = 0.036). No significant prognostic implications of other cytogenetic abnormalities were found associated with overall survival and PFS.

CONCLUSIONSChinese MM patients had similar cytogenetic abnormalities compared with the previous reported studies. However, the prognostic significance of FISH aberrations were not clearly determined and further study is required.

OBJECTIVETo evaluate of the role of transcranial electrical stimulation motor evoked potential (TES-MEP) in combination with cortical somatosensory evoked potential (CSEP) monitoring during the spinal surgery.

METHODSTES-MEP on bilateral anterior tibial muscle and flexor hallucal brevis and CSEP on bilateral posterior tibial nerve were observed simultaneously on 293 patients during spinal surgery from July 2006 to April 2009. Intravenous anesthesia was employed in all the patients, a part of which were added low dose of sevoflurane or muscle relaxant. The results of TES-MEP, CSEP and combined monitoring were analyzed statistically. Pre-operative and post-operative motor and sensory functions of spinal cord were compared.

RESULTSSuccess rate of TES-MEP, CSEP and combined monitoring was 90.8%, 96.9% and 100% respectively. For the judgment of motor function of spinal cord, the sensitivity of TES-MEP and CSEP was 100% and 89.3% respectively and the specificity of 98.4% and 96.9%. The Youden index of the two methods was 0.984 and 0.862. For sensory function, the sensitivity of them was 76.7% and 93.3% respectively and the specificity of 98.7% and 98.0%. The Youden index was 0.754 and 0.913. The sensitivity of combined monitoring was 100%, with the specificity of 96.9%. The Youden index was 0.969.

CONCLUSIONSThe precision of monitoring motor function of spinal cord with TES-MEP is higher than that with CSEP, however, for sensory function, CSEP is more precise. The sensitivity and precision of combined monitoring for spinal cord function were apparently better than that of unitary TES-MEP or CSEP. The combined TES-MEP and CSEP monitoring is a relatively ideal method.
