Objective To explore the application value of quantitative analysis of tissue diffusion by ultrasound elastography in evaluating the evolution of achilles tendinopathy and indirectly reflecting the feature of tendon biomechanics.Methods Rabbits underwent 0.1 ml (group M) or 0.3 ml (group S)collagenase or 0.2 ml saline (group C) injection.The percentage of area displaying blue (％AREA) in the area of interest was measured by the diffusion quantitative technique of ultrasound elastography at baseline and 1,3,7 and 14 days after model.The achilles tendon was obtained for pathological examination to observe the changes of collagen fibers and tested to measure the maximum tensile load by the universal testing machine.Results (1) The ％AREAs in group M and S at 1,3,7 and 14 days after model were smaller than those in group C (P ＜0.05),and reached its lowest value at 3 days after model.％ AREA in groupSwas significant lower than that in group M at 3 or 7 days after model (P ＜0.05).(2) The maximum tensile loads in group M at 1,3 and 7 days after model were smaller than those in group C (P ＜0.05),but there was no significant difference between group M and C at 14 days after model (P ＞0.05).The maximum tensile load in group S was significant lower than those in group M and C after model (P ＜0.05),and arrived its lowest point at 3 days after model.(3) The ％AREA was positively associated with the maximum tensile load of achilles tendon (r =0.87,P ＜0.001).Conclusions Ultrasound elastography can dynamically monitor the evolution of achilles tendinopathy and reflect the biomechanical state of achilles tendon.

BACKGROUND:The knee joint acts as the body’s largest and most complex joint, which is a commonly seen perplex in patients because of synovium and cartilage diseases. Moreover, clinical physicians are often confused on the ultrasonic diagnosis of synovium and cartilage diseases.
OBJECTIVE: To review the ultrasound misdiagnosed cases of knee cartilage and synovial lesions and to summarize the common misconceptions and discrimination methods.
METHODS: A retrospective analysis was performed in the ultrasound misdiagnosed cases of knee cartilage and synovial lesions reported from 2002 to 2014, and then the common misconceptions and corresponding identification methods were summarized.
RESULTS AND CONCLUSION: High-frequency ultrasound is most likely to have six “mistaken ideas” addressing knee cartilage and synovial lesions: (1) cartilage degeneration; (2) synovial calcification; (3) echo intensity from synovial lesions; (4) blood flow in the synovium; (5) synovial effusion; (6) lesions involving intraarticular structures. High-frequency ultrasound runs through dynamical observation and contrast observation of bilateral knee joint lesions, which is a valuable imaging method for diagnosis of cartilage and synovial diseases based on vigilance at the “mistaken ideas” and mastery of the distinguishing ideas and methods.

Objective To investigate the feasibility of Antituberculotic?loaded bone cement (ATLBC) prepared by mix?ing the anti?TB drugs Rifampicin (RFP), Isoniazid (INH), Pyrazinamid (PZA), Moxifloxacin (MFX) with Palacos R PMMA bone cement in Total Joint Arthroplasty treatment for Joint Tuberculosis. Methods Forty grams of Palacos R bone cement powder without antibiotics was mixed with 1 or 2 grams of RFP, INH, PZA and MFX respectively. According to ISO 5833:2002 stan?dard, 8 groups of ATLBC standard test specimen were prepared as experiment group and Palacos R PMMA bone cement with?out antibiotics was prepared as control group. Physical properties (such as the average dough time, curing time, maximum tem?perature), mechanical strength (such as the compressive strength, the bending resistance strength, the modulus of elasticity) and the concentrations of eluant drug in different time points of ATLBC were detected. Results In RFP (1 g), RFP (2 g), INH (1 g) and INH (2 g) group, the average dough time and curing time were longer than those in control group, which exceeded the standard scope of ISO, while the average maximum temperature was significantly lower than that in control group. The INH ( 1 g) group and INH (2 g) group hardened after mixing for 14 days. The RFP (1 g) group and RFP (2 g) group hardened after mixing for 30 days. Twenty minutes after mixing and hardening, the compressive strength, bending resistance strength and modulus of elastic?ity were significantly lower than the specified values of ISO standard. The physical properties and mechanical strength in PZA ( 1 g) group, PZA (2 g) group, MFX (1 g) group, MFX (2 g) group and control group were in accordance with the specified values of ISO standard, and they hardened after 20 minutes. In RFP (1 g) group, RFP (2 g) group, INH (1 g) group, INH (2 g) group, PZA (1 g) group, PZA (2 g) group, MFX (1 g) group and MFX (2 g) group, the concentration of eluant could maintain for 3 days, 7 days, 90 days, 90 days, 45 days, 60 days, 60 days and 60 days respectively. Conclusion RFP and INH mixing with Palacos R PMMA bone cement can hinder the aggregation of bone cement so they are unsuitable for preparing ATLBC. PZA and MFX mixing with Palacos R PMMA bone cement do not affect the physical properties of bone cement, with excellent mechanical strength and elu?tion properties. Because the minimal inhibitory concentration of PZA is higher and its antimicrobial activity maintains shorter time, while MFX maintains longer time in antimicrobial activity, it's more suitable for the preparation of ATLBC.

Objective To evaluate appropriate timing of laparoscopic cholecystectomy (LC) after percutaneous transhepatie gallbladder drainage (PTGD) for the treatment of acute cholecystitis (AC).Methods To compare the clinical data of 74 patients with acute cholecystitis who underwent laparoscopic cholecystectomy at different time after PTGD,Including the degree of gallbladder inflammation,operation time,intraoperative blood loss,the rate of conversion to laparotomy,length of stay and total cost.74 cases were divided into 3 groups,group 1 (n =31),operated within 4 w,group 2 (n =22),between 4 and 8 w,group 3 (n =21),after 8 w.Results Group 2 was better than group 1 and group 3 in operation time,blood loss,length of stay and total cost,the difference was statistically significant (P ＜ 0.05).Conclusion Laparoscopic cholecystectomy performed after 4-8 weeks PTGD is the best time in terms of less risk of operation,shorter hospital stay,lower cost,and better quality of life.

Objective:Hidden hunger remains a severe public health problem that affects millions of people worldwide.In China,challenges related to dietary imbalance and hidden hunger persist.Micronutrient inadequacy deserves more attention among adolescents,given its vital role in their growth and development;however,this problem appears to have been largely ignored.High school students,in particular,are often at a high risk of hidden hunger but have limited assessment tools available.Therefore,this study aims to revise the hidden hunger assessment scale for high school students(HHAS-HSS)in China and assess its reliability and validity.Methods:Based on a literature review,expert consultation,pre-experiment,and formal survey,a hidden hunger assessment scale was revised for high school students.The formal survey involved 9 336 high school students in 11 of the 16 cities in Anhui Province,China,and 9038 valid questionnaires were collected and included in the analysis.The item analysis,internal consistency reliability,test-retest reliability,content validity,exploratory factor analysis,and confirmatory factor analysis of the HHAS-HSS were examined.Results:The HHAS-HSS included a total of 4 dimensions and 12 items:"vegetables and food diversity"(three items),"fruits and dairy products"(three items),"micronutrient-dense foods"(four items),and"health condition and eating habits"(two items).The results showed a Cronbach's alpha of 0.758,a split-half reliability of 0.829,and a test-retest reliability of 0.793,indicating good internal consistency.Using the Bartlett's test and Kaiser-Meyer-Olkin test(KMO)to test the exploratory factor analysis presented a four-factor model of the HHAS-HSS,the KMO value was 0.820(P＜0.001),which indicated the possibility for factor confirmatory factor analysis.Using the maximum variance rotation method,four factors were obtained,and the cumulative variance explained rate was 57.974％.Confirmatory factor analysis also supported the division of the scale into four dimensions,and the fitting indices were x2=1417.656,x2/df=29.534,goodness-of-fit index=0.974,adjusted goodnesss-of-fit index=0.958,parsimonious goodness-of-fit index=0.600,normed fit index=0.938,incremental fit index=0.940,Tucker-Lewis index=0.917,comparative fit index=0.939,and root mean square error of approximation=0.056.Except for x2/df,all the indices reached the fitting standard,and the above results showed that the construct validity of the scale reached an acceptable level.Conclusions:The HHAS-HSS has good validity and reliability for Chinese high school students.It is a convenient self-report measure of hidden hunger risk.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

To investigate the feasibility and clinical effects of the laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique for the treatment of complex ureteral stricture. 
 Methods: The clinical data of 16 patients with complicated ureteral stricture treated by the laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique from February 2016 to June 2018 were retrospectively analyzed. All 16 patients were iatrogenic stenosis. There were 4 cases of severe hydronephrosis in the affected side, 7 cases of moderate hydronephrosis, and 5 cases of mild hydronephrosis. According to the specific location and length of the ureteral stricture, the corresponding surgical method was selected. 
 Results: All patients successfully completed the operation without conversion to open surgery and organ injury. After the operation, the patients were followed up for 8-18 months. The hydronephrosis of all patients was relieved to varying degrees, and no ureteral restenosis occurred. 
 Conclusion: The laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique can accurately locate the stenosis segment, test the anastomosis effect, expand the inflammatory stenosis, and improve the end-to-end anastomosis of the distal ureteral stricture, which is a new and effective technique for the treatment of complex ureteral strictures.

OBJECTIVE: To verify the clinical effect of acupoint embedding therapy on post-stroke constipation. METHODS: The multi-central randomized controlled trial was adopted. 210 patients of post-stroke constipation were divided into an acupoint embedding group (105 cases, 4 cases dropped off) and a sham-embedding group (105 cases, 6 cases dropped off). In the acupoint embedding group, the acupoint embedding therapy was used at Tianshu (ST 25), Daheng (SP 15), Xiawan (CV 10), Zhongwan (CV 12), Qihai (CV 6), Guanyuan (CV 4) and Daju (ST 27). In the sham-embedding group, the sham-embedding therapy was given, in which, the acupoint selection, needle devices and manipulation were the same as the acupoint embedding group. But, no absorbable surgical suture was used in the needle tube. The treatment was given once every two weeks and 4 treatments were required in either group. It was to compare the weekly average complete spontaneous bowel movements (CSBMs) during treatment (from the 3rd to the 8th week) between the two groups, the weekly average spontaneous bowel movements (SBMs), Bristol stool form score (BSFS), the score of the patient assessment of constipation quality of life questionnaire (PAC-QOL) and the score of defecation difficulty before and after treatment. RESULTS: The percentage of the cases with weekly average CSBMs ≥ 3 times in the patients of the acupoint embedding group was higher markedly than the sham-embedding group [91.1% (92/101) vs 43.4% (43/99), <0.01]. Compared with the values before treatment, the weekly average SBMs and BSFS scores after treatment were all increased obviously in the two groups (<0.01), and PAC-QOL score and the score of defecation difficulty were reduced remarkably (<0.01). After treatment, the increase range of SBMs and BSFS scores, as well as the decrease range of PAC-QOL score and the defecation difficulty score in the acupoint embedding group were all higher than the sham-embedding group respectively (<0.05). CONCLUSION The acupoint embedding therapy remarkably increases the spontaneous bowel movements, improves in feces form and defecation difficulty and strengthens the quality of life in the patients of post-stroke constipation.
