OBJECTIVE: To investigate specific technique and clinical effects of closed folding top consolidation maneuver combined with splint fixation maneuver for consolidation and cedar bark external fixation splint for the treatment of double fractures of distal ulna and radius in children. METHODS: From January 2017 to December 2019, 17 children with double fractures of distal ulna and radius were treated with closed folded apex consolidation maneuver, including 13 males and 4 females, aged from 4 to 11 years old with an average of (7.29±2.34) years old. The fractures were fixed with cedar bark splint and followed up for 6 months, and alignment of fracture was evaluated according to the latest X-rays by follow up, and function of the affected limbs was evaluated by Anderson forearm function evaluation criteria. RESULTS: Fifteen of 17 children were successfully reset immediately, and 2 children were successfully reset again. The average fixed time was (25.00±3.35) days. At 6 months of follow up, 12 patients got excellent results, 3 good, 2 fair, and 0 poor according to Anderson forearm function evaluation criteria. The position of all children were larger than 3/4, and 10 children were received anatomical reduction, alignment of 4 children was less than 10°, 3 children was less than 15°. No complications such as fracture displacement, nonunion, compartment syndrome, and forearm rotation dysfunction occurred. CONCLUSION Restoration of distal radius double fracture in children with the combination of the closed folding and top fixation maneuver and splint fixation maneuver has advantages of higher success rate, lower complications, which could reduce operating difficultyand pain of patients.

BACKGROUND: Taxanes are an essential class of antineoplastic agents used to treat various cancers and are a fundamental cause of hypersensitivity reactions. In addition, other adverse events, such as bone marrow toxicity and peripheral neuropathy, can lead to chemotherapy discontinuation. This study aimed to evaluate the safety of taxanes in the real world. METHODS: Taxane-associated adverse events were identified by the Medical Dictionary for Regulatory Activities Preferred Terms and analyzed and compared by mining the US Food and Drug Administration Adverse Event Reporting System pharmacovigilance database from January 2004 to December 2019. Reported adverse events, such as hypersensitivity reaction, bone marrow toxicity, and peripheral neuropathy, were analyzed with the following signal detection algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), multi-item gamma Poisson shrinker (MGPS), Bayesian confidence propagation neural network (BCPNN), and logistic regression methods. Adverse outcome events and death outcome rates were compared between different taxane groups using Pearson's χ2 test, whereas significance was determined at P < 0.05 with a 95% confidence interval (CI). RESULTS: A total of 966 reports of hypersensitivity reactions, 1109 reports of bone marrow toxicity, and 1374 reports of peripheral neuropathy were analyzed. Compared with paclitaxel and docetaxel, bone marrow toxicity following the use of nab-paclitaxel had the highest ROR of 6.45 (95% two-sided CI, 6.05-6.88), PRR of 5.66, (χ2 = 4342.98), information component of 2.50 (95% one-sided CI = 2.34), and empirical Bayes geometric mean of 5.64 (95% one-sided CI = 5.34). Peripheral neuropathy following the use of nab-paclitaxel showed a higher ROR of 12.78 (95% two-sided CI, 11.55-14.14), PRR of 12.16 (χ2 = 4060.88), information component of 3.59 (95% one-sided CI = 3.25), and empirical Bayes geometric mean of 12.07 (95% one-sided CI = 11.09). CONCLUSIONS The results showed that bone marrow toxicity and peripheral neuropathy were the major adverse events induced by taxanes. Nab-paclitaxel exhibited the highest potential for taxane-associated adverse events. Further research in the future is warranted to explain taxane-associated adverse effects in real-world circumstances.

BACKGROUNDPreterm birth is a common cause of death in newborns and may result from many determinants, but evidence for the socioeconomic and environmental determinants of preterm birth in Tibetan women of childbearing age is limited. The aim of this study was to understand the current status of preterm birth in native Tibetan women and investigate the socioeconomic and environmental determinants.

METHODSData were drawn from a cohort study which was conducted from August 2006 to August 2012 in rural Lhasa, Tibet, China. A total of 1419 Tibetan pregnant women were followed from 20 weeks' gestation until delivery; the loss to follow-up rate was 4.69%. The incidence of preterm birth was estimated to show the status of preterm births in Tibet. Logistic regression models for longitudinal data were established, and odds ratios (ORs) together with 95% confidence intervals (CIs) were used to evaluate the association between the occurrence of preterm birth and 16 selected potential determinants based on the hierarchical conceptual frame.

RESULTSThe incidence of preterm birth was 4.58% (95% CI = 3.55-5.80%). After adjusting for health-related variables of the mothers and newborns, socioeconomic and environmental determinants associated with preterm birth included season (spring: OR = 0.28, 95% CI = 0.09-0.84; autumn: OR = 0.21, 95% CI = 0.06-0.69; and winter: OR = 0.31, 95% CI = 0.12-0.82) and calendar year of delivery (2010: OR = 5.03, 95% CI = 1.24-20.35; 2009: OR = 6.62, 95% CI = 1.75-25.10; and 2007-2008: OR = 5.93, 95% CI = 1.47-23.90).

CONCLUSIONSThe incidence of preterm birth among native Tibetan women was low and there was a decreasing trend in recent years; however, it is still essential to strengthen seasonal maternal care, extend the spacing between pregnancies, and reinforce adequate maternal nutrition.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

BACKGROUNDMajor atrial coronary arteries, including the sinus node artery (SNA), were commonly found in the areas involved in atrial fibrillation (AF) ablation and could cause difficulties in achieving linear block at the left atrial (LA) roof. The SNA is a major atrial coronary artery of the atrial coronary circulation. This study aimed to determine impact of the origin of SNA on recurrence of AF after pulmonary vein isolation (PVI) in patients with paroxysmal AF.

METHODSSeventy-eight patients underwent coronary angiography for suspected coronary heart disease, followed by catheter ablation for paroxysmal AF. According to the origin of SNA from angiographic findings, they were divided into right SNA group (SNA originating from the right coronary artery) and left SNA group (SNA originating from the left circumflex artery). Guided by an electroanatomic mapping system, circumferential pulmonary vein ablation (CPVA) was performed in both groups and PVI was the procedural endpoint. All patients were followed up at 1, 3, 6, 9 and 12 months post-ablation. Recurrence was defined as any episode of atrial tachyarrhythmias (ATAs), including AF, atrial flutter or atrial tachycardia, that lasted longer than 30 seconds after a blanking period of 3 months.

RESULTSThe SNA originated from the right coronary artery in 34 patients (43.6%) and the left circumflex artery in 44 patients (56.4%). Freedom from AF and antiarrhythmic drugs (AADs) at 1 year was 67.9% (53/78) for all patients. After 1 year follow-up, 79.4% (27/34) in right SNA group and 59.1% (26/44) in left SNA group (P = 0.042) were in sinus rhythm. On multivariate analysis, left atrium size (HR = 1.451, 95%CI: 1.240 - 1.697, P < 0.001) and a left SNA (HR = 6.22, 95%CI: 2.01 - 19.25, P = 0.002) were the independent predictors of AF recurrence.

CONCLUSIONSThe left SNA is more frequent in the patients with paroxysmal AF. After one year follow-up, the presence of a left SNA was identified as an independent predictor of AF recurrence after CPVA in paroxysmal AF.

BACKGROUNDDrug treatment for secondary hyperparathyroidism caused by chronic renal failure may be available at the early stage of the disease, but it is not as effective for serious patients. The aim of the study was to evaluate the effect of total parathyroidectomy combined with forearm autotransplantation in the uremic patients with secondary hyperparathyroidism.

METHODSFrom September 1999 through September 2006, parathroidectomy and autotransplantation was performed in 20 patients. The coherence between the results of preoperative parathyroid ultrasonography and surgical exploration were compared. The serum calcium concentration and intact parathyroid hormone (iPTH) were monitored preoperatively, intraoperatively, and postoperatively.

RESULTSA total of 71 hyperplastic parathyroid glands were resected in the 20 patients. The accordance rate of parathyroid localization between B-ultrasonography and intraoperative exploration was 94.4%. The average iPTH value was (110.90 +/- 67.42) ng/L, (433.80 +/- 243.72) ng/L, (48.80 +/- 42.69) ng/L, (229.04 +/- 172.68) ng/L and (232.39 +/- 224.05) ng/L at day 1, 2, 3, 7, 30 after operation respectively. The clinical symptoms were ameliorated and the levels of serum calcium concentration were controlled within the normal range after operation. Recurrent secondary hyperparathyroidism had happened in 1 case, 4 years postoperatively because of the development of autograft hyperplasia, and in another case 2 years postoperatively due to remnant of neck parathyroid glands. The clinical symptoms were all alleviated after re-operation. No surgical complication had occurred in any of the patients.

CONCLUSIONSThe total parathyroidectomy with forearm autotransplantation is feasible, safe, and effective for patients with secondary hyperparathyroidism in the short term. The long-term effects should be further investigated.

OBJECTIVETo analyze the current use of reperfusion strategies and the outcomes of patients with ST elevation acute coronary syndromes (ACS) in China.

METHODSA total of 518 consecutive patients (371 male and 147 females, mean age 65 +/- 11) with ST elevation ACS or newly discovered left bundle branch block were registered from 20 hospitals from 5 regions (ranging from large regional centre hospitals to small county hospitals) in China. Patient general characteristics, reperfusion patterns and outcomes were analyzed. Patients were followed up for 3 months.

RESULTSThe median time from pain onset to presentation at the hospital was 4 hours. Pre-hospital delay > 12 hours was found in 20% patients. Fifty-six percent patients (292/518) underwent reperfusion therapy (134 with primary percutaneous coronary intervention and 158 with fibrinolysis). The median time from admission to reperfusion (door-to-needle) was 65 min in fibrinolysis group and 110 min (door-to-cath) in primary PCI group respectively. Urokinase was used in 67% (106/158) patients underwent fibrinolysis. Multivariate logistic regression analysis showed that age >/= 75 years (P < 0.01), previous myocardial infarction (P < 0.01) and history of congestive heart failure (P < 0.05) were associated with no reperfusion therapy. Mortality and congestive heart failure rates were significantly higher in patients with no reperfusion therapy not only at discharge (P < 0.01) but also at 3 months (P < 0.01) compared to patients underwent reperfusion. The incidence of combined outcomes (death or MI, and death, MI or Strobe) was also higher in patients without reperfusion therapy at 3 months (all P < 0.01) compared to patients underwent reperfusion. There were no differences on combined outcomes between fibrinolysis and primary PCI subgroups.

CONCLUSIONReperfusion therapy was the primary treatment of choice to improve the outcomes of patients with ST elevation ACS. Strategies to increase reperfusion therapy rate for ST elevation ACS are urgently needed in China.
