Nephrocalcinosis is often accompanied by kidney stone disease. In recent years, more and more nephrocalcinosis has been found to be caused by a monogenic disease, and its pathogenesis has not been fully elucidated. With the development of molecular genetics, more than 30 genes have been found to be the causative genes of nephrocalcinosis. At the same time, with the widespread development of genetic testing technology, more patients have received early diagnosis and timely intervention. This article reviews the clinical and basic research progress of monogenic nephrocalcinosis.

BACKGROUND:Elderly patients with hip surgery in the department of orthopedics are often associated with a variety of diseases, and easily suffer from complications after implantation.
OBJECTIVE:To analyze the characteristics and the factors of complications and mortality of the elderly patients with hip disease by different orthopedic implants.
METHODS:249 patients accepted total hip arthroplasty, femoral head replacement, proximal femoral nail, Gamma nail, and holow screw fixation. We analyzed patients’ age, sex, hip disease type, anesthesia risk assessment, psychological and psychiatric factors, admission hemoglobin, preoperative albumin, Charlson comorbidity index, ways of anesthesia, orthopedic implants, operation time, intraoperative bleeding, length of stay, postoperative complications, mortality and survival.
RESULTS AND CONCLUSION:Hip disease in the elderly was repaired with five kinds of implants. (1) There were significant differences in age, anesthesia risk assessment, hemoglobin on admission and preoperative albumin, length of stay, duration and intraoperative bleeding. No significant difference in complications and death was found. (2) The most significant indicators affecting complications were length of stay and albumin on admission and preoperative Charlson comorbidity index. The most significant
indicators affecting death were age and hemoglobin on admission and preoperative Charlson comorbidity index. (3) Significance of comprehensive assessment of patients before placement: during hip operation, implants were not the factors that affected the complications and mortality after placement, patients with artificial joint replacement could get out of bed early, and complications and mortality could be reduced. Elderly patients with anemia, hypoalbuminemia and Charlson comorbidity index≥3 should be given a high degree of attention. We should assess Charlson comorbidity index as early as possible, positively treat complications, correct anemia and hypoproteinemia, prevent the occurrence of complications, shorten the length of hospital stay, and reduce the mortality after placement.

For screening the potential drugs as anti-liver fibrosis candidates, we established a high- throughput drug screening cell model based on COL1A1 promoter. The activity of COL1A1 promoter and luciferase reporter gene can be elevated by TGF-β1, and inhibited by candidate drugs. We constructed a recombined plasmid with COL1A1 promoter and luciferase reporter gene pGL4.17, the activity of COL1A1 promoter was reflected by fluorescence intensity. COL1A1 promoter activity was detected by Dual-Luciferase Reporter Assay System, it came that the relative luciferase activity of COL1A1 promoter was 15.98 times higher than that of control group induced by TGF-β1, showing the recombined plasmid could be used in cell model. The recombined plasmid was transfected into human hepatic stellate cells LX2, detected the effect of potential drugs, and obtained a stable expression system through stable transfection and monoclonal cell culture. A sample which could reduce COL1A1 promoter activity signally by our cell model, decreased collagen I mRNA and protein expression detected by real-time RT-PCR and Western blotting. It indicates this novel cell model can be used in high-throughput drug screening of potential anti-liver fibrosis drugs.

BACKGROUND: During conventional treatment for bone tuberculosis, there is a low effective concentration of anti-tuberculosis drugs, and the therapeutic effect is poor. OBJECTIVE:To develop a new biomaterial as a slow-release artificial carrier that can be directly implanted into the surrounding tissue of bone tuberculosis, maintain a certain anti-tuberculosis drug concentration for a long time, thereby playing an effective therapeutic action. METHODS:Rifampicin/polylactic acid/glycolic acid microspheres and isoniazid/polylactic acid/glycolic acid microspheres were prepared using the emulsion-solvent evaporation method. Usingα-cyanoacrylate, a biological adhesive, two kinds of microspheres were processed into a long-term slow-release bicomponent drug carrier. Then, in vitro release characteristics of the dual-drug sustained-release carrier were observed. After that, the dual-drug sustained-release carrier was implanted into rabbit intertrochanteric femur bone defects for observing drug release concentrations, histocompatibility and bone defect healing at different time points after drug delivery carrier implantation. RESULTS AND CONCLUSION:For rifampicin/polylactic acid/glycolic acid microspheres, the mean particle size was (240±13)μm, and the drug loading load rate was (26±1.5)%. For isoniazid/polylactic acid/glycolic acid microspheres, the mean particle size was (250±10)μm, and drug loading rate was (28±1.8)%. The in vitro cumulative release rate could reach 80%for rifampicin and 90%for isoniazid at day 90. The in vivo released concentration of rifampicin and isoniazid within 90 days was (0.5±0.4) and (0.6±0.3)μg/g, respectively. There were a smal amount of infiltrated neutrophils between the fascia and muscle fibers after the drug delivery carrier was implanted, and the amount of neutrophils in the muscle were reduced significantly at day 59. X-ray plain film showed that bone defects decreased obviously in size. These findings indicate that this dual-drug sustained-release carrier can maintain a certain anti-tuberculosis drug concentration in the surrounding tissues of bone tuberculosis, which is expected to provide a new type of dual-drug delivery carrier in the surgical treatment of bone tuberculosis.

Objective To compare the difference of ELISA and LABScreen in detecting HLA antibodies and evaluate their effects on allograft rejection.Methods Consecutive patients undergoing kidney transplantion from November,2008 to December,2009 in the First Affiliated Hospital and the following up patients during the same period,with abnormal Scr who had completed kidney biopsies,were included in this study.Patients' HLA antibodies were detected by ELISA (Lambda antigen tray,LATTM) and LABScreen Mix Beads (LABScreen MIX,One Lambda,Canoga Park,CA,USA) or LABScreen Single antigen beads (LABScreenTM single antigen beads,One Lambda,Canoga Park,CA,USA).Patients' Scr were also detected at different time potints.Results There were 277 patietns included.Among them 145 (52.3％) cases were HLA antibody positive detected by LABScreen,which including 118 cases ELISA negative but LABScreen positive,and 27 cases both ELISA and LABScreen positive.No case was ELISA positive but LABScreen negative.Among 118 cases which were LABScreen positive but ELISA negative,41 (34.7％) cases happened acute or chronic rejection.However,only 24 cases happened rejection in 132 double negative cases (18.2％,P =0.003).There were 31％ patients in rejection group while only 12.8％ patients (P=0.01) in non-rejection group whose HLA antibody fluorescence intensity detected by LABScreen single antigen beads still increased two weeks after transplantation.Conclusion LABScreen is more sensitive than ELISA in detecting HLA antibodies,and its result highly correlates with the incidence of allograft rejection.

Objective To analyze the causes for the thigh pain after treatment of femoral trochanteric fractures by proximal femoral nail antirotation Ⅱ( PFNA Ⅱ) . Methods Included in this ret-rospective study were 236 patients who had been treated by us for femoral trochanteric fracture from October 2011 to December 2015. They were 103 men and 133 women, aged from 42 to 86 years (average, 50. 3 years) . According to AO classification, 13 cases belonged to type 31-A1. 2, 32 to type 31-A1. 3, 35 to type 31-A2. 1, 27 to type 31-A2. 2, 33 to type 31-A2. 3, 38 to type 31-A3. 1, 39 to type 31-A3. 2 and 19 to type 31-A3. 3. All the fractures were single, fresh and closed and treated with PFNAⅡinternal fixation. Results This cohort was followed up for 8 to 26 months (average, 13. 2 months). Nonunion occurred in one case who had to accept artificial hip replacement. The remaining 235 cases obtained bony union after 22 to 39 weeks (average, 29. 3 weeks). By the Harris evaluation at final follow-ups, the affected hips scored from 81 to 93 points (average, 85. 1 points) . Post-operative thigh pain was reported in 19 cases (8. 05％) . The causes included varied anatomic morphology of the proximal femur in 6 cases, distal defects of the intramadullary nails in 4, insufficient stability of internal fixation or uneven biomecanical distribution in 3, unskillful operation in 2, and severe oesteoporosis in 4. Avascular necrosis of femoral head was not observed during follow-ups. Conclusions Postoperative thigh pain is worthy of serious atention from orthopaedists following PFNA Ⅱtreatment of femoral trochanteric fractures. PFNA Ⅱshould be modified according to the specific Chinese features of the proximal femur, especially in the respects of anterior arch and distal structure of the main nail and lateral declination as well.
