Objective To explore the risk factors of early femoral head necrosis in patients with femoral neck fracture after operation,and to establish a nomogram prediction model.Methods A total of 167 patients with femoral neck fracture from Jan-uary 2020 to April 2022 were selected and divided into necrosis group and non-necrosis group according to whether femoral head necrosis occurred in the early postoperative period.There were 21 males and 17 females in the necrosis group,aged from 33 to 72 years old,with an average of(53.49±10.96)years old,and the time from injury to operation ranged from 40 to 67 hours,with average time of(53.46±7.23)hours.There were 72 males and 57 females in the non-necrosis group,aged from 18 to 83 years,with an average of(52.78±12.55)years old,and the time from injury to operation was 18 to 65 hours,with an aver-age time of(39.88±7.79)hours.The potential influencing factors,including patient gender,diabetes mellitus,hypertension,chronic liver disease,posterior inclination angle of the femoral head,operation mode,fracture displacement,fracture line loca-tion,preoperative braking traction,screw arrangement mode,reduction quality,age,body mass index(BMI),and injury to operation time were subjected to single factor analysis.Logistic multivariate regression analysis was conducted for factors with a significance level of P＜0.05.Results The incidence of femoral head necrosis in 167 patients with femoral neck fracture was 22.76％.The following factors were identified as independent risk factors for early postoperative femoral head necrosis in pa-tients with femoral neck fractures:coexisting diabetes[OR=5.139,95％CI(1.405,18.793),P=0.013],displaced fracture[OR=3.723,95％CI(1.105,12.541),P=0.034],preoperative immobilization[OR=3.444,95％CI(1.038,11.427),P=0.043],quality of reduction[OR=3.524,95％CI(1.676,7.411),P=0.001],and time from injury to surgery[OR=1.270,95％CI(1.154,1.399),P=0.000].The Hosmer-Lemeshow goodness-of-fit test(x2=3.951,P=0.862),the area under the receiver operator characteristic(ROC)curve was 0.944[P＜0.001,95％CI(0.903,0.987)],with a sensitivity of 89.50％,the specificity was 88.40％,the maxi-mum Youden index was 0.779,and the overall trend of the model correction curve was close to the ideal curve.Model regres-sion equation was Z=1.637 × diabetes+1.314× fracture displacement+1.237 × preoperative braking traction+1.260 × reduc-tion quality+0.239 ×injury to operation time-18.310.Conclusion The occurrence of early femoral head necrosis in patients with femoral neck fracture postoperatively is affected by multiple factors.The risk early warning model established according to the factors has good predictive efficacy.

ObjectiveTo investigate the protective effects and its mechanism of ischemia postconditioning (IPO) in hepatic ischemia-reperfusion injury (IRI) in liver cirrhotic rats.MethodsThirty liver cirrhotic Sprague-Dawley (SD) rats were randomly divided into three groups according to the random table methods: ischemia postconditioning (IPO) group, IRI group, and pure hepatectomy (PH) group with 10 rats in each group. Rats in IPO group underwent partial hepatectomy (40%), and the first portal was occluded for 20 min, then 3 times of ischemia-reperfusion were performed, and ifnally continuous reperfusion. Rats in IRI group underwent partial hepatectomy (40%), and the ifrst portal was occluded for 20 min, then continuous reperfusion was performed. Rats in PH group underwent partial hepatectomy (40%) only. Inferior vena cava blood was collected at 6, 24 h after operation. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), proportion of cluster of differentiation (CD) 4+, CD8+, regulatory T cells (Treg) and levels of interleukin (IL)-4, IL-10 were tested. Comparison of three groups was conducted by one way analysis of variance and pairwise comparison by LSD-t test.ResultsAfter 6 h reperfusion, levels of ALT and AST in IPO group [(1 623±378) , (1 993±469) U/L] were signiifcantly lower than those in IRI group [(2 690±549) , (3 020±577) U/L] (LSD-t=-4.21,-3.72; P<0.05). After 24 h reperfusion, levels of ALT and AST in IPO group [(307±76) , (555±137) U/L] were still signiifcantly lower than those in IRI group [(518±105) , (1 050±355) U/L] (LSD-t=-4.06,-3.37;P<0.05). After 6 h reperfusion, proportion of CD4+, CD8+, CD4+/CD8+ ratio, Treg, and levels of IL-4, IL-10 in IPO group were (57±5) %, (25±3) %, 2.3±0.5, (8.9±0.4) %, (1.27±0.25) mg/L, (0.61±0.03) mg/L, respectively. While in IRI group, they were (52±6)%, (12±3) %, 4.5±0.8, (7.3±0.3) %, (0.66±0.11) mg/L, (0.34±0.06) mg/L, respectively. In IPO group, CD8+, Treg, IL-4 and IL-10 increased signiifcantly, while CD4+/CD8+ ratio decreased signiifcantly, compared with those in IRI group (LSD-t= 7.74, 6.67, 5.52, 9.31,-6.69;P<0.05).ConclusionIPO can prevent from hepatic IRI injury in liver cirrhotic rats through decreasing the immune injury.

OBJECTIVETo elucidate the clinicopathological features of solid pseudopapillary tumor (SPT) of the pancreas.

METHODSEight patients with SPT of the pancreas admitted from August 1996 to March 2005 were retrospectively analyzed.

RESULTSAll the 8 patients were female with an average age of 25.3 (13-41) years. The primary clinical manifestations included abdominal mass (n = 3), vague abdominal pain (n = 3), and duodenal obstruction (n = 1). SPT was occasionally found in one patient during physical examination. Six tumors located at the head and the other two in the body and tail of the pancreas. Pancreaticoduodenectomies were performed in 4 patients, tumor enucleations in 2, distal pancreatectomies in 1, and palliative internal drainage with a cystoenterotomy in the other one with an unresectable huge cystic lesion. All patients were alive on an average follow-up of 37.8 (8-103) months.

CONCLUSIONSPT occurs mainly in adolescent and young females, and satisfactory outcome may be achieved with active and appropriate surgeries.

OBJECTIVETo evaluate the hemocompatibility of a small-caliber expanded polytetrafluoroethylene vessel with silk fibroin coating sulfonated by low temperature plasma treatment.

METHODSThe composite blood vessel was prepared by first coating the small-caliber expanded polytetrafluoroethylene vessel with silk fibroin followed by sulfonation by low temperature plasma treatment. After hemolysis test in vitro, dynamic coagulation time test, blood platelet adhesion test, and recalcification time test were performed to evaluate the hemocompatibility of the composite blood vessel.

RESULTSScanning electronic microscopy revealed obvious platelets adhesion on the conventional artificial (control) vessel, which seldom occurred on the composite vessel. The curve of absorbance-clotting time of the composite vessel declined more slowly than that of the control vessel. The recalcification time of the composite blood vessel averaged 603 s, significantly longer than that of the control vessel (480 s, P = 0.000).

CONCLUSIONThe composite blood vessel has good antithrombotic activity and hemocompatibility as a promising vascular prosthesis.

Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

OBJECTIVETo evaluate metabolic abnormalities in patients with mesial temporal lobe epilepsy (MTLE) with proton magnetic resonance spectroscopy (MRS) using a 3. 0T MR scanner.

METHODSSixty-three patients (32 women and 31 men) with diagnosed MTLE underwent diagnostic MR imaging (MRI) and proton MRS using a 3. 0T MR scanner. The clinical history and interictal epileptiform discharges (IEDs) were recorded. Sixteen healthy volunteers served as control. The results of proton MRS were compared with the findings of electroencephalogram and structural MRI findings.

RESULTSTwenty-seven of the 63 patients with MTLE showed unilateral hippocampal sclerosis, and 9 showed bilateral hippocampal sclerosis. The concentration ratio of N-acytelaspartate (NAA)/[creatine (Cr) + choline (Cho)] in the hippocampal region of MTLE patients (0.64 +/- 0.07) was significantly lower than control (0.80 +/- 0.05, P = 0.023). In the patients with unilateral hippocampal sclerosis, NAA/(Cr + Cho) in the hippocampal region ipsilateral to the sclerotic hippocampus (0.56 +/- 0.06) was significantly lower than the ratio in the contralateral hippocampal region (0.69 +/- 0.07, P < 0.001). There was significant difference in hippocampal NAA/(Cr + Cho) between the refractory patients and the non-refractory patients (0.64 +/- 0.05 vs. 0.71 +/- 0.07, P = 0.04). Forty-five patients were lateralized by IEDs, while 49 patients were lateralized by metabolite ratio. And lateralization determined by proton MRS and IEDs was concordant in 33 patients.

CONCLUSIONSMRS as a noninvasive tool adds helpful metabolite information to routine MRI in evaluation of MTLE. The method is well established and should be a routine clinical application in the investigation of epilepsy.

Objective:To investigate the clinical significance of excessive inlet view in fluoroscopy-assisted placement of sacroiliac screws.Methods:Included for this prospective study were 47 patients with unstable pelvic fracture who had been admitted to Department of Orthopaedic Trauma, Xi'an Honghui Hospital between January 2020 and January 2021. There were 30 males and 17 females, with a mean age of 39.4 years (from 25 to 66 years). By the Tile classification, 21 fractures were type B and 26 ones type C. The inlet view and the angle of excessive inlet view were measured before operation. The intraoperative placement of sacroiliac screws was assisted by C-arm fluoroscopy navigation in the excessive inlet view. The positions of sacroiliac screws were verified by CT or O-arm fluoroscopy after operation. The screw placement time, fracture reduction quality, fracture healing time, and pelvic function at the last follow-up were recorded.Results:A total of 67 screws were implanted in the 47 patients, including 56 sacroiliac screws. The insertion time for each screw averaged 19.9 min (from 9 to 31 min); the angle of excessive inlet view averaged 17.38° (from 12.1° to 24.8°). Verification by O-arm fluoroscopy or CT revealed that all sacroiliac screws were located in the sacral canal without dislocation or breaking through the cortical bone. By the postoperative Matta scoring, the reduction was excellent in 22 cases, good in 17, acceptable in 6, and poor in 2, giving an excellent to good rate of 83.0%(39/47). The average follow-up time for the 47 patients was 9.5 months (from 5 to 15 months); fracture healing time averaged 10.5 weeks (from 7 to 16 weeks). By the Mejeed scoring at the last follow-up, the pelvic function was excellent in 26 cases, good in 15 and acceptable in 6, giving an excellent to good rate of 87.2% (41/47).Conclusions:Fluoroscopy in the excessive inlet view is a simple and easy intraoperative technique. It can improve accuracy and safety of sacroiliac screw placement because it allows clear identification of the posterior border of the sacrum and effectively avoids iatrogenic injury to the sacral nerve caused by screws breaking through the bone cortex.

Case reports are valuable clinical evidence in traditional Chinese medicine (TCM). However, the general reporting quality is suboptimal. A working group comprising 20 members was set up to develop systematic recommendations on case report in Chinese medicine (CARC). The working group (CARC group) developed a primary checklist based on reviewing the general reporting quality of case reports in TCM and thorough internal discussion. Two-round consensus process had been carried out among clinical experts, evidence-based medicine methodologists, medical journal editors and clinical practitioners with designated questionnaire embedded with the primary checklist. In total, 118 participants from 17 provinces of China and Korea completed the questionnaires. Their feedback was analyzed and discussed by the CARC group. The checklist was amended accordingly, and the final version, comprising 16-item, is presented here. Under the framework of CARC recommendations, the reporting quality of case reports in TCM can be improved.

Objective:To analyze the functions and indications， formulation， dosage form and medication characteristics of Chinese patent medicines in the 2020 edition of Chinese Pharmacopoeia （part Ⅰ） for treating cough of children， and to provide ideas for the clinical rational application and provide reference for the research and development of new cough medicines for children. Method:The name， dosage form， formulation， functions and indications， usage and dosage， and other information of Chinese patent medicines for cough were collected from the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， then relevant information was input into Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine v2.0， and data analysis and mining were carried out through the analysis module of prescription medication rule， VOSviewer 1.6.14 was used to make drug clustering network view of Chinese patent medicines for the treatment of exogenous wind cold， exogenous wind heat and phlegm heat cough. Result:In the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， a total of 75 kinds of Chinese patent medicines for treating cough of children were collected， including 34 kinds of Chinese patent medicines for adults and children， 41 kinds of Chinese patent medicines for children only. There were 7 types of traditional Chinese medicine syndromes， such as wind-cold attacking the lung， wind-heat invading the lung and phlegm-heat obstructing the lung. There were 45 Chinese patent medicines for treating exogenous cough， accounting for 60%， among which 35 kinds were used for exogenous wind-heat cough and 10 kinds were used for wind-cold cough. There were 30 kinds of Chinese patent medicines for treating internal injury cough， including 19 kinds of medicines for phlegm heat obstructing the lung， 4 kinds of medicines for phlegm dampness containing the lung and phlegm food stagnation， 2 kinds of medicines for Yin-deficiency lung heat， 1 kind of medicine for the lung and spleen Qi-deficiency. The formulation analysis showed that Glycyrrhizae Radix et Rhizoma， Platycodonis Radix， Scutellariae Radix， Armeniacae Semen Amarum and Citri Reticulatae Pericarpium appeared frequently， which were mainly cold， bitter and sweet herbs， mainly belonged to the lung and stomach meridians. According to the analysis of administration and dosage forms， 71 kinds of Chinese patent medicines were administered through gastrointestinal tract， including 20 kinds of granules， 15 kinds of oral liquids， others included syrups， pills， capsules， tablets， powers， etc. Only 2 suppositories and 2 injections were administered by nongastrointestinal tract. The usage and dosage of most Chinese patent medicines were not clear. Conclusion:In the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， the main syndromes of Chinese patent medicines for cough of children are exogenous wind-heat and phlegm-heat obstruction in the lung. Most of the Chinese medicines are cold， bitter and sweet， and their meridians are mainly lung and stomach meridians. Scutellariae Radix， Lonicerae Japonicae Flos and Forsythiae Fructus are the most common medicines of exogenous wind heat syndrome. Perillae Folium， Citri Reticulatae Pericarpium and Ephedrae Herba are the most common medicines of exogenous wind cold syndrome. Meanwhile， Scutellariae Radix， Platycodonis Radix and Armeniacae Semen Amarum are the most common medicines of phlegm heat obstructing the lung syndrome. At present， the dosage forms of Chinese patent medicines used for treating cough of children are too few and the dosage labeling is not comprehensive， so it is necessary to further strengthen the research and development of new Chinese medicines suitable for characteristics of children.
