Objective:To compare the clinical effect of femoral neck system (FNS) and cannulated compression screw internal fixation in the treatment of femoral neck fractures in young and middle-aged patients.Methods:The databases of CNKI, Wanfang Data Knowledge Service Platform, VIP, Chinese Medical Journal Full-text Database, PubMed, Embase, Web of Science and Cochrane Library were searched. The intraoperative blood loss, intraoperative fluoroscopy times, hospital stay, fracture healing time, Harris hip function score, partial weight-bearing time and complication rate were extracted to compare the clinical efficacy of the two surgical methods. Stata18.0 statistical software was used for meta-analysis.Results:A total of 699 patients from 11 studies were included in this study. Compared with cannulated compression screw internal fixation, the FNS had a shorter operation time [ WMD= -8.54, 95% CI(-14.87, -2.21), P=0.008], fewer intraoperative fluoroscopy times[ WMD= -8.29, 95% CI(-11.45, -5.12), P< 0.001], a shorter fracture healing time [ WMD=-1.59, 95% CI(-2.49, -0.68), P=0.001], a shorter partial weight-bearing time[ WMD=-3.45, 95% CI(-4.43, -2.46), P<0.001], a lower incidence of postoperative complications [ RR=0.41, 95% CI(0.22, 0.76), P= 0.004], and a lower incidence of postoperative nonunion [ RR=0.40, 95% CI(0.18, 0.88), P=0.022]. Meanwhile, the FNS group had more intraoperative blood loss [ WMD=9.53, 95% CI(2.70, 16.35), P=0.006] and a higher Harris hip function score at the last follow-up [ WMD=3.50, 95% CI(2.11, 4.89), P<0.001] than the cannulated compression screw internal fixation group. There were no statistically significant differences in the length of hospital stay [ WMD=-0.48, 95% CI(-0.82, -0.13), P=0.092] or the incidence of femoral head necrosis [ RR=0.57, 95% CI(0.26, 1.24), P=0.159] between the two groups. Conclusion:Compared with cannulated compression screw internal fixation in the treatment of femoral neck fracture in young and middle-aged patients, FNS has more intraoperative blood loss, but it has more advantages in operation time, intraoperative blood loss, intraoperative fluoroscopy times, postoperative fracture healing time, Harris hip function score, partial weight-bearing time, postoperative nonunion rate and postoperative complications rate.

Objective:To establish the norm of the Chinese version of Karitane Parenting Confidence Scale (KPCS) in urban areas of China.Methods:From August to December 2017, the parents of 2 216 children (<36 months old) were selected from 15 cities (Beijing, Lianyungang, Hangzhou, Chengdu, Xi′an, Guangzhou, Changsha, Jinan, Guiyang, Ningbo, Dalian, Qinhuangdao, Maanshan, Chongqing and Wuhan) in 14 provinces by stratified random sampling. The general demographic characteristics and parents′ parenting confidence were collected by a self-made questionnaire and KPCS Chinese version. The percentile norm was established. P 3, P10 and P 25 were used as the criteria to define the degree of lack of parenting confidence. Results:The age of mothers was (30.67±4.29). The age of the father was (32.50±4.99) years old. There were 726 (32.76%), 759 (34.25%) and 731 (32.99%) infants in 6-12, 12-23 and 24-35 months old groups. The total scores of P 50, P 25, P 10 and P 3 of KPCS (Chinese version) of infant parents in urban areas in China were 41, 38, 33, and 29 respectively. When the scores of parents were 34-37, 30-33, and ≤ 29, they were judged as mild, moderate, and severe lack of parenting confidence. There was no significant difference in the Chinese version of KPCS between parents of different age groups and parents of different gender (χ2=3.53, P=0.171; χ2=1.41, P=0.236). Each factor score≤ P 3 is defined as the boundary score, and the corresponding boundary scores of "parenting" "support" and "competence" were 13, 9, and 5 respectively. Conclusion:The Chinese version of KPCS can be used to assess the parenting confidence of infants in urban areas of China. It can used as one of the bases for scientific and objective evaluation of the parenting status of families.

Objective To investigate the clinical manifestations and nerve electrophysiological abnormalities of the patients with multiple myeloma peripheral neuropathy (MMPN). Methods The clinical data of 35 patients with MMPN diagnosed in Shanxi Provincial People's Hospital from March 2010 to June 2018 were retrospectively analyzed. All patients received nerve electrophysiology examination, including nerve conductive velocity (NCV) and skin sympathetic response (SSR). Results The most common symptoms of peripheral nerve involvement for MMPN patients were sensory abnormalities (25 cases, 71%), including root pains (3 cases, 9%), pain ablation of the upper or lower limbs (18 cases, 51%), dyskinesia (15 cases, 43%), disappeared or reduced knee or ankle reflex (13 cases, 37%) and automatic sympathetic disorders (20 cases, 57%). Nerve electrophysiological tests showed 29 cases (83%) were involved in abnormal sensory nerve conduction velocity (SCV) or motor nerve conduction velocity (MCV), including 13 cases of upper limb abnormality in NCV, 5 cases of prolonged incubation in upper limb, and 10 cases of decreased amplitude;8 cases of lower limb abnormality in NCV, 6 cases of prolonged incubation in lower limb, and 4 cases of decreased amplitude. SSR test showed abnormalities were found in 17 patients (49%), including 8 cases of upper limb abnormality in SRR, 2 cases of prolonged incubation in upper limb, and 7 cases of decreased amplitude, 1 case of disappeared waveform; 6 cases of lower limb abnormality in SRR, 1 case of prolonged incubation in lower limb, and 4 cases of decreased amplitude, 2 cases of disappeared waveform; 3 cases of abnormal upper and lower limbs. Conclusions The most common peripheral nerve damages of MM are "sock and gloveˉlike" sensory ablation, accompanied with the involvement of automatic nerve damage. NCV is the major method to diagnose MMPN, and SSR plays an important role in the detection of sympathetic nerve damage of MMPN.

Pancreatic portal hypertension (PPH),which accounts for about 5％ of extrahepatic portal hypertension cases,is mainly caused by pancreatic tumor,chronic pancreatitis and pancreatic ductal lithiasis.The pathogenesis and pathological characteristics of PPH are attributed to anatomical structure between splenic vein and pancreas.It is different from cirrhotic portal hypertension,PPH patients may present with less esophageal and gastric fundus varices,but more significant gastric body varices.The portal vein radiography is recognized as the golden standard for PPH diagnosis.There are two types of treatment modalities for PPH,symptomatic treatment and pathogenesis-based treatment.In clinically,we should take careful consideration into portal hypertension and primary disease,aim to resolve causes and manage complication concurrently.

Objective To discuss the width of ischiofemoral space (IFS) in asymptomatic adults and the related influence of physiological parameters (including age,sex,height,body weight,intertuberous distance,femoral offset,lesser trochanter height,etc).Methods Pelvic MSCT data of 61 adults without hip pain symptom were analyzed retrospectively.The indexes were measured,including the width of IFS,intertuberous distance,femoral offset,lesser trochanter height,femoral neck long axis,femoral neck angle and ischial angle.The correlation between the width of IFS and the physiological parameters was analyzed.Results The height,body weight,width of IFS,femoral offset,lesser trochanter height and femoral neck long axis of male subjects were larger than those of female subjects (all P＜0.05),while the intertuberous distance and ischial angle of male subjects were smaller than those of female subjects (both P＜0.001).There was positive correlation between the width of IFS and femoral neck long axis (P＜0.001).Negative correlation was found between the width of IFS and the age,intertuberous distance,femoral neck angle,ischial angle,respectively (all P＜0.001).No correlation between IFS and the height,body weight,femoral offset,lesser trochanter height was found (all P＞0.05).Conclusion MSCT can be applied for measurement and evaluation of relative anatomy images of ischiofemoral impingement.The structure of pelvis is different between male and female,and this may be the reason of why female patients are more likely to suffer from ischiofemoral impingement.

Phytochemicals are reported to provide various biological functions leading to the promotion of health as well as the reduced risk of chronic diseases. Fat-soluble plant pigments, carotenoids, are extensively studied micronutrient phytochemicals for their potential health benefits. It is noteworthy that specific carotenoids may be responsible for different protective effects against certain diseases. In addition, each carotenoid can be obtained from different types of plant foods. Considering the fact that the phytochemical content in foods can vary according to, but not limited to, the varieties and culture conditions, it is important to establish a database of phytochemicals in locally produced plant foods. Currently, information on individual carotenoid content in plant foods commonly consumed in Korea is lacking. As the first step to support the production and consumption of sustainable local plant foods, carotenoids and total phenolic contents of plant foods commonly consumed in Korea are presented and their potential biological functions are discussed in this review.

Objective To investigate the clinical predictive value of rheumatoid factor (RF), anti-keratin antibodies (AKA), anti-cyclic citrullinated peptide (anti-CCP) antibody and anti-perinuclear factor (APF) in the transition from undifferentiated arthritis (UA) to rheumatoid arthritis (RA), and to analyze the clinical relevant factors. Methods 271 patients with UA who were followed up for a year were enrolled into the investigation. RF was measured by the rate scatting immunity method. APF and AKA were detected by immuniofluorescence method(IFA). Anti-CCP was measured by ELISA. Erythrocyte sedimentation rate (ESR) was analyzed by Wilcoxon method. The duration of morning stiffness, the numbers of swelling and tender joints, tender joints involved and DAS28 score were recorded and analyzed. Results 99% patients who had four-antibody-positive finally convetted from UA to RA. The conversation rate for those who had two or more than two antibody-positive was 83.0% and 65.9% respectively. The sensitivity and specificity of RF and anti-CCP antibody-positive in those who converted from UA to RA was 77.8% and 80.5% respectively. The percentage of polyarticular swelling in antibody-negative, one-antibody-positive, two-antibody-positive, three-antibody- positive and four-antibody-positive was 48%, 57%, 59%, 70% and 70% respectively. Meanwhile, the percentage of multi-small-joint involvement was 71%, 71%, 72%, 76% and 83% respectively. The proportion of elbow involvement in antibody-negative patients was 72%, which was the highest among all joint area involvement. The conversion differences of the group with more than 3 swelling joints or more than 3 small joints involvement ranked the first and second in frequency. Conclusion The combined detection of these autoantibodies could increase the specificity of early diagnosis of RA. The more positive antibodies present, the more likely the concersion form UA to RA. The sensitivity and specificity of RF and anti-CCP-positive is high, so the latter is expected to become one of the diagnostic criteria. The polyarticular swelling and multi-small-joint involvement are valuable in predicting the transformation from UA to RA.

Objective To improve the diagnosis and management of solid-pseudopapillary tumor (SPT) of the pancreas. MethodsTwenty-two SPT patients were retrospectively reviewed and divided into two groups, misdiagnosed group and those with preoperatively correct diagnosis. ResultsAbout one half (46%) SPT cases were misdiagnosed preoperatively. With time SPT tends to invade its capsule resulting in impossibility of radical resection, and increased medical expenses. ConclusionsAlthough SPT is of low degree malignant, and the prognosis after surgical resection is satisfactory, misdiagnosis and preoperative misdiagnosis and inappropriate management still cost the patients increased expenses and inhospital stay.
