OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and metabolic syndrome (MS) in patients with impaired glucose tolerance (IGT).Methods:A total of 415 patients with abnormal glucose tolerance were screened by oral glucose tolerance test in Changsha Traditional Chinese Medicine Hospital (Changsha Eighth Hospital) from October 2015 to September 2019. General data were collected and blood routine and biochemical indexes were detected. There were 193 cases in the observation group and 222 cases in the control group. The RDW and other clinical indicators were compared between the two groups, the correlation between RDW and other indicators was analyzed, and the risk factors of metabolic syndrome were analyzed.Results:⑴ The RDW, systolic blood pressure (SBP), diastolic blood pressure (DBP), height (Ht), weight (Wt), waist circumferenc (Wc), triglyceride (TG), cholesterol (CHOL), low density lipoprotein (LDL), creatinine (Cr), uric acid (UA), alanine aminotransferase (ALT), high sensitive C-reactive protein (hs-CRP), body mass index (BMI) of the observation group were significantly higher than those of the control group, while the high density lipoprotein (HDL) was significantly lower than that of the control group, with statistically significant difference ( P<0.05); ⑵ correlation analysis showed that RDW was positively correlated with SBP, DBP, Ht, Wt, Wc, TG, CHOL, Cr, UA, ALT, hs-CRP, BMI, and negatively correlated with HDL ( P<0.05); ⑶ binary logistic regression analysis showed that RDW, Wt, Wc, CHOL, HDL, LDL and hs-CRP were independent risk factors for MS in patients with impaired glucose tolerance. Conclusions:The increase of RDW is a predictor of metabolic syndrome in people with abnormal glucose tolerance, which may provide some reference value for the prevention and treatment of metabolic syndrome.

Objective To explore dose-effect relationship of biomechanical parameters in treating atlantoaxial joint disor-der by slimming manipulation.Methods From October 2022 to May 2023,18 patients with atlantoaxial joint disorders were treated,including 10 males and 8 females;aged from 24 to 27 years old with an average of(25.50±l.10)years old;CT of cer-vical vertebra showed 16 patients with right side distortion and 2 patients with left side distortion.The mechanical parameters of treatment of atlantoaxial joint disorder by tendon relaxation manipulation were measured by wearing massage manipulation gloves.The magnitude,frequency and mechanical curve of force during tendon relaxation and starting force,pulling force,pulling time and mechanical curve during rehabilitation were quantified,the differences between the affected and contralateral manipulations were compared.Results The maximum force and frequency of Fengchi(GB20)on the affected side were(19.82±2.02)N and(116.83±14.49)times/min,and opposite side were(13.87±2.19)N and(188.89±16.03)times/min,re-spectively.There were statistically difference in the maximum force and frequency of both sides(P＜0.05).The maximum force and frequency of Quepen(ST12)on the affected side were(14.44±3.27)N and(139.06±28.47)times/min,and those on the opposite side were(9.41±1.38)N and(142.50±28.47)times/min.There was difference in maximum force on both sides(P＜0.05).The starting force,turning force and turning time of the affected side were(14.16±5.98)N,(11.56±6.63)N,(0.14±0.03)S,and the contralateral side were(8.94±3.39)N,(8.30±4.64)N,(0.18±0.04)S,respectively.The difference of starting force,turning force and turning time on both sides were statistically significant(P＜0.05).Conclusion By applying a light re-laxation force on the affected side,the mechanical balance between cervical vertebrae could be restored,and recovery trend of atlantoaxial joint disorder could be strengthened.On this basis,the atlantoaxial odontoid process could be reversed by applying a light rotation force,which reflects the characteristics of high safety of the manipulation.

OBJECTIVETo determine the clinicopathologic characteristics and the relationship between related gene expression and pathobiologic behavior of pancreatic mucinous noncystic adenocarcinoma.

METHODSAmong the 249 pancreatic carcinoma cases from the department files, 6 tumors were identified to meet the pathologic criteria of colloid carcinoma. Envision immunohistochemical staining technique was used to detect expression of p21(ras), p21(WAF1), p16, p33(ING1), p53, ATM, MDM2, PCNA, Cyclins (D1, D3, A, B and E). Intra- and extra- cellular mucin production were determined by AB-PAS staining. Clinically, all of 6 cases were followed to June, 2003.

RESULTSIn all 6 cases, the tumors were located in the head of the pancreas and all displayed similar microscopic findings. Duodenal invasion was seen in 4 cases and perineural invasion was seen in 1 case. Tumor metastasis in the liver was seen in 2 cases and in the regional lymph nodes in 2 cases. Positive immunostaining was seen in 5 cases with p21(ras), 3 cases with p21(WAF1), 1 case with p16, 4 cases with p33(ING1), 2 cases with p53, 3 cases with ATM, 3 cases with MDM2, 6 cases with PCNA, 3 cases with cyclinA, 3 cases with cyclinD1, 4 cases with cyclinD3, 4 cases with cyclinB and 6 cases with cyclinE. Both extracellular and intracellular mucin was strongly positive for AB-PAS staining. Clinical follow-up found that 2 patients died of their tumors at 14 and 20 months. Three patients were alive after 28, 49 and 87 months of follow-up. One case were lost contact.

CONCLUSIONSPancreatic mucinous noncystic adenocarcinoma has distinct morphologic features and biologic behavior. Multiple gene products including many cyclins may be involved in the pathogenesis of pancreatic colloid carcinoma. The tumor has an aggressive behavior with a high frequency of invasion and metastases, though the prognosis could be better than that of ordinary ductal adenocarcinoma of pancreas.

BACKGROUNDMany studies have shown the superior efficacy of budesonide (BUD)/formoterol (FORM) maintenance and reliever therapy, but still lack evidence of its efficacy in Chinese asthma patients in a relative large patient-group. We finished this research to compare BUD/FORM maintenance and reliever therapy and high-dose salmeterol (SALM)/fluticasone (FP) maintenance plus an as-needed short-acting β(2)-agonist in Chinese patients with persistent uncontrolled asthma. This was a post hoc analysis based on a 6-month, multicenter, randomized, double-blind study (NCT00242775).

METHODSA total of 222 eligible asthma patients from nine centers in China were randomized to either BUD/FORM+as-needed BUD/FORM (160/4.5 µg/inhalation) (640/18 µg/d; n = 111), or SALM/FP+as-needed terbutaline (0.4 mg/inhalation) (100/1000 µg/d; n = 111). The primary endpoint was time to first severe exacerbation while secondary endpoints included various measures of pulmonary function, symptom control and quality-of-life.

RESULTSTime to first severe exacerbation over six months was lower with the BUD/FORM than with the SALM/FP treatment (risk ratio = 0.52, 95%CI 0.22 - 1.22), but the difference did not achieve statistical significance (P = 0.13). The cumulative number of severe exacerbations in the BUD/FORM group was lower than in the SALM/FP group (7.2% vs. 13.5%; risk ratio = 0.45, P = 0.028). BUD/FORM produced significantly better improvements in reliever use, cumulative mild exacerbations, symptom-free days (%), and morning/evening peak expiratory flow (PEF) than SALM/FP (P < 0.05 in all cases). The two groups achieved similar improvements in their time to first mild exacerbation, forced expiratory volume in one second (FEV(1)), asthma control questionnaire and asthma symptom scores, and percentage of nights with awakening(s). Both treatments were well tolerated.

CONCLUSIONSIn Chinese patients with persistent asthma, BUD/FORM decreased severe and mild exacerbations, decreased reliever use, increased symptom-free days, and improved morning/evening PEF compared with SALM/FP. There were no significant differences in time to first severe exacerbation or other assessments regarding daily asthma control between BUD/FORM and SALM/FP. BUD/FORM was more effective in this Chinese sub-group than in the total cohort involved in the original study.

OBJECTIVETo report a case of critical illness polyneuropathy (CIP) with Parkinson disease and discuss the development, clinical features and early diagnosis of this condition.

METHODSThe clinical data of a patient with CIP and Parkinson's disease and the relevant literature were reviewed.

RESULTSThis case showed no typical disease course of sepsis, and the condition exacerbated rapidly. The patient presented initially with abnormal homeostasis, followed by rapid onset of respiratory muscle weakness to require mechanical ventilation, but no limb weaknesses were detected. Intravenous antibiotics and aggressive treatment of sepsis did not produce any positive responses to wean from mechanical ventilation. Examinations of creatine kinase and cerebrospinal fluid showed no abnormalities. Electromyography and nerve conduction studies demonstrated declined nerve conduction velocity and decreased sensory and motor muscle action potentials, suggesting the possibility of CIP.

CONCLUSIONIn patients with Parkinson disease, the occurrence of sepsis with prolonged mechanical ventilation and limb weakness indicates the necessity of neurophysiological examination, muscle biopsies and laboratory tests, which may help detect CIP in the early phase. Proper interventions of sepsis may reduce the likeliness of CIP. Elimination of the risk factors and aggressive management of sepsis can be effective measures for preventing CIP.

OBJECTIVETo explore the genetic etiology of fetuses with multicystic dysplastic kidney (MCDK) by chromosome microarray analysis (CMA).

METHODSSeventy-two fetuses with MCDK were analyzed with conventional cytogenetic technique, among which 30 fetuses with a normal karyotype were subjected to CMA analysis with Affymetrix CytoScan HD arrays by following the manufacturer's protocol. The data was analyzed with ChAS software.

RESULTSConventional cytogenetic technique has revealed three fetuses (4.2%) with identifiable chromosomal aberrations. CMA analysis has detected pathogenic CNVs in 5 fetuses (16.7%), which included two well-known microdeletion or microduplication syndromes, i.e., 17q12 microdeletion syndrome and Williams-Beuren syndrome (WBS) and three submicroscopic imbalances at 4q35.2, 22q13.33, and 1p33. PEX26, FKBP6, TUBGCP6, ALG12, and CYP4A11 are likely the causative genes.

CONCLUSIONCMA can identify the submicroscopic imbalances unidentifiable by conventional cytogenetic technique, and therefore has a significant role in prenatal diagnosis and genetic counseling. The detection rate of pathogenic CNVs in fetuses with MCDK was 16.7% by CMA. 17q12 microdeletion syndrome and WBS are associated with MCDK. Mutations of PEX26, FKBP6, TUBGCP6, ALG12, and CYP4A11 genes may be the causes for MCDK.
