OBJECTIVETo compare the clinical effects between anterior cervical discectomy and fusion(ACDF) combined with anterior cervical corpectomy and fusion(ACCF) and cervical posterior single open-door laminoplasty with mini-titanium plate fixation in treating three-segment cervical spondylotic myelopathy.

METHODSThe clinical data of 63 patients (39 males and 24 females) with three-segment cervical spondylotic myelopathy underwent surgical treatment from March 2014 to March 2016 were retrospectively analyzed. Among them, 43 cases were treated by ACDF combined with ACCF(anterior group), and 20 cases were treated by cervical posterior single open-door laminoplasty with mini-titanium plate fixation(posterior group). Operative time, intraoperative blood loss, postoperative complications were compared between two groups. And according to JOA score to evaluate the clinical effect.

RESULTSAll the patients were follow-up from 16 to 40 months with an average of 25.8 months. Operative time of anterior group and posterior group were (123.70±6.21) min and(118.70±5.41) min, respectively, there was no significant difference between two groups(>0.05). Intraoperative blood loss of anterior group and posterior group were (85.23±7.51) ml and (107.18±9.41) ml, respectively, there was significant difference between two groups(<0.05). In anterior group, axial symptoms occurred in 6 cases, dysphagia in 1 case, and no C₅ nerve root palsy, hoarseness and choking cough were found, the incidence rate of complication was 16.3%(7/43); and in posterior group, axial symptoms occurred in 5 cases, C5 nerve root palsy in 1 case, and no dysphagia, hoarseness and choking cough were found, the incidence rate of complication was 30.0%(6/20); there was significant defference in incidence rate of complication between two group(<0.05). At 1 week after operation and final follow-up, the JOA scores of anterior group were obviously better than that of posterior group(<0.05).

CONCLUSIONSAbove-mintioned two surgical treatment for cervical spondylotic myelopathy can provide instantly stability, the method of ACDF combined with ACCF was obviously better that of the method of cervical posterior single open-door laminoplasty in intraoperative blood loss, the incidence rate of complications, clinical effect.Thus, for the treatment of three-segment cervical spondylotic myelopathy, the method of ACDF combined with ACCF would be firstly chosen.

OBJECTIVE: To analyze the prognostic value of R-ISS staging combined with "Multiple-Hits" in patients with multiple myeloma (MM), and to detected the effect of different "Multiple- Hits" combinations to the prognosis of the patients. METHODS: The 220 MM patients treated in the hematology department of People's Hospital of Xinjiang Uygur Autonomous Region from April 2013 to October 2019 were enrolled and retrospective analyzed. All the patients were detected by FISH. The effects of R-ISS staging combined with "Multiple-Hits" and different "Multiple-Hits" combinations to the prognosis of the patients were compared. RESULTS: For the patients at R-ISS stage II and III, the median progression-free survival (PFS) time, overall survival (OS) time and duration of response (DOR) time in "Multiple-Hits" patients were all shorter than those without high-risk cytogenetic abnormality (HRCA) and those with only one type of HRCA (P<0.05), while the TTR (time to response) was significantly prolonged (P<0.05). For the prognosis of the patients among the three different "Multiple-Hits" combinations(1q21+ combined with del(17p), 1q21+ combined with t(14;16) and combined 1q21+ combined with t(4;14)), 1q21+ combined with del(17p) showed the worst prognosis. CONCLUSION The patients with Different "Multiple-Hits" combinations shows different prognosis. The R-ISS staging combination with "Multiple-Hits" is more conducive to accurately judging the prognosis of MM patients.

Objective: To investigate the distribution characteristics of LymphGen genotyping in a diffuse large B-cell lymphoma (DLBCL) population and verify its prognostic value. Methods: We collected the clinical data and paraffin-embedded tumor tissue samples of 155 patients with newly diagnosed DLBCL in the People's Hospital of Xinjiang Uygur Autonomous Region from June 2014 to December 2020. DNA was extracted from tumor tissue and 475 gene mutations were detected by next-generation sequencing technology. We investigated the distribution of LymphGen genotyping in the DLBCL population, patients with different COO genotypes in the Xinjiang region, and their effects on PFS and OS. Results: ①Among 155 patients, 105 patients (67.7%) could be genotyped, including 14 (9.0%) for MCD, 26 (16.8%) for BN2, 10 (6.5%) for N1, 8 (5.2%) for EZB, 27 (17.4%) for A53, and 20 (12.9%) for ST2. ②The distribution of each gene subtype was different in different cell origin (COO) types (P=0.021) . ST2 was dominant in the germinal center type (GCB) group (28.8%) , and A53 and MCD were dominant in the non-GCB group (35.8%, 17.0%) . The BN2 type was the most common in both groups (23.1%, 26.4%) . ③There were statistically significant differences in progression-free survival (PFS) and overall survival (OS) among different gene subtypes (P=0.031 and 0.005, respectively) . N1 and A53 had poor prognosis. The 2-year PFS and OS rates of N1 were both (21.3±18.4) %, and the 3-year PFS and OS rates of A53 were (60.9±11.3) %, (46.8±10.9) %, respectively. ④ The 3-year PFS and OS rates of MCD were the best, but the 5-year PFS and OS rates were worse. ⑤In the ROC curve of LymphGen genotyping for OS prediction, the AUC was 0.66, showing a certain degree of differentiation. Conclusion: LymphGen genotyping in the DLBCL population was different from previous reports and was of great significance for the prognosis of patients with DLBCL.

OBJECTIVE: To investigate the mutational spectrum in young patients with diffuse large B-cell lymphoma (DLBCL) based on next generation sequencing (NGS), and to provide a basis for in-depth understanding of the molecular biological characteristics and accurate prognosis of young DLBCL. METHODS: From March 2009 to March 2021, 68 young DLBCL patients with complete initial diagnosis data from the Department of Hematology, The People's Hospital Xinjiang Uygur Autonomous Region were retrospectively analyzed, and their paraffin-embedded tissues were subjected to targeted sequencing analysis by NGS technology (including 475 Target genes), and the differences in gene mutation profiles and signaling pathways between high-risk patients with aaIPI ≥2 and low-intermediate risk patients with aaIPI <2 were compared. RESULTS: A total of 44 high-frequency mutation genes were detected in 68 young DLBCL patients. By comparing the high-frequency mutation genes in aaIPI high-risk group and low-intermediate risk group, it was found that CARD11 mutation in aaIPI high-risk group was significantly higher than that in low-intermediate risk group (P =0.002), while MGA mutation (P =0.037) only appeared in the aaIPI high-risk group, and SPEN mutation (P =0.004) only appeared in the aaIPI low-intermediate risk group. The high-frequency mutation genes and clinical indicators of the aaIPI high-risk group were included in the survival analysis, and the results showed that TP53 (P =0.009, P =0.027), POU2AF1 (P =0.003, P =0.006) and CCND3 (P =0.040, P =0.014) genes mutations were associated with worse PFS and OS, while B2M was associated with better PFS (P =0.014) and OS (P =0.013). Multivariate COX regression analysis showed that the TP53, POU2AF1 and CCND3 were independent risk factors for PFS（P ＝0.021，P =0.005，P =0.020） and OS（P ＝0.042，P =0.010，P =0.013）. CONCLUSION The aaIPI staging combination with molecular biology markers is more conducive to accurately judging the prognosis of young DLBCL patients. TP53, POU2AF1 and CCND3 mutations predict worse survival in the patients with the aaIPI high-risk group.

BACKGROUND: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. METHODS: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. RESULTS: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05). CONCLUSION Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.
