Osteoporotic fractures(OPF) refer to the fractures caused by minor violence in the state of osteoporosis, seriously threatening the life and health of elderly patients. Drug and surgical therapies have limitations such as single targets, diverse adverse reactions, and poor prognosis. Kidney-tonifying traditional Chinese medicine(TCM) has good potential in the treatment of OPF. TCM can promote the healing of OPF by promoting angiogenesis in the early stage of bone healing, promoting osteogenic differentiation of bone marrow mesenchymal stem cells in the stage of bone repair, maintaining the balance of osteogenic and osteoclastic system in the stage of bone remodeling, and regulating the oxidative stress responses throughout the process of OPF healing. TCM can alleviate the pathological state of osteoporosis and promote fracture healing in OPF patients via multiple pathways and targets, demonstrating the advantages and potential of biphasic regulation.

OBJECTIVES: To investigate the effect of Ching Shum Pills (CSP) for alleviating non-alcoholic fatty liver disease (NAFLD) and the underlying mechanism. METHODS: In a mouse model of NAFLD, the therapeutic effect of CSP was evaluated by measuring serum glucose, lipid profiles (TC, TG, LDL-C, HDL-C), and hepatic function markers. Network pharmacology was employed to identify active compounds in CSP and their targets using TCMSP, HERB, SwissTargetPrediction, GeneCards, OMIM, and DisGeNET. Protein-protein interaction (PPI) networks, Gene Ontology (GO), and KEGG pathway analyses were conducted. Molecular docking (AutoDock Vina) was used to assess the compound-target binding affinities. Quantitative real-time PCR (qRT-PCR) was used to validate the mRNA expressions of the core genes in the liver tissue of the mouse models. RESULTS: In the mouse model of NAFLD, treatment with CSP significantly reduced body weight gain and serum TG levels of the mice, and high-dose CSP treatment resulted in obvious reduction of ALT levels and hepatic fat accumulation. Network pharmacology analysis identified quercetin and 2-monolinolenin as the key bioactives in CSP, which target TNF, AKT1, IL6, TP53, and ALB. Docking simulations suggested strong binding between the two core compounds and their target proteins. The results of qRT-PCR showed that high-fat diet induced significant downregulation of Tp53, Cpt1, and Ppara expressions in mice, which was effectively reversed by CSP treatment. CONCLUSIONS CSP can improve lipid metabolism disorders in NAFLD mice through a regulatory mechanism involving multiple targets and pathways to reduce liver fat accumulation and protect liver function. The key components in CSP such as quercetin and linolenic acid monoacylglycerol may participate in the regulation of such metabolic processes as fatty acid oxidation by targeting TP53.

Objective: The Schizophrenia Cognition Rating Scale (SCoRS) is an interview-based assessment tool for evaluating the cognitive deficit and daily functioning of patients with schizophrenia. Methods: Sixty-eight patients with schizophrenia and 68 age- and sex-matched healthy individuals were recruited to validate the Chinese version of SCoRS in this study. All participants underwent cognitive assessment using the SCoRS, which was verified by the Brief Assessment of Cognition in Schizophrenia (BACS), and the UCSD Performance-based Skills Assessment, Brief Version (UPSA-B). Patients with schizophrenia were additionally assessed using the Positive and Negative Syndrome Scale (PANSS). Results: SCoRS ratings reported by patients (SCoRS-S), those reported by the interviewer (SCoRS-I), and SCoRS global scores (SCoRS-G) showed significant correlation with all subscales of the BACS and the UPSA-B. On receiver operating characteristic curve analysis, SCoRS-S, SCoRS-I, and SCoRS-G significantly differentiated patients with schizophrenia from healthy controls. Moreover, SCoRS-S and SCoRS-I ratings showed positive correlation with the negative symptoms and general symptoms of PANSS. Conclusion The Chinese version of SCoRS showed good discriminant, concurrent, and external validity, suggesting that it is a useful and convenient tool for assessment of cognitive function among Mandarin-speaking patients with schizophrenia in clinical practice.

Objectives: Chronic obstructive pulmonary disease (COPD) is a risk factor for osteoporosis. Nevertheless, much remains unclear regarding the bone metabolism dynamics associated with COPD. The present study focuses on the associations between the COPD severity and serum bone metabolism biomarkers. Methods: We enrolled 40 patients who visited the orthopedics departments at our institutions and underwent dual-energy X-ray absorptiometry between September 2015 and December 2017. Only male osteoporosis patients over 45 years of age were included, and 5 patients were excluded due to disease or use of internal medicines affecting bone metabolism. All subjects underwent lung function testing, spine radiography, and blood tests. We measured percent forced expiratory volume in 1 second (%FEV1), which reflects COPD severity, and we examined the relationships between %FEV1and serum levels of bone metabolism biomarkers. Results: All subjects were diagnosed with osteoporosis based on T-scores. %FEV1 correlated with body weight, body mass index (BMI), and Z-score/T-scores. %FEV1 moderately correlated with serum levels of alkaline phosphatase (ALP), procollagen type 1 N-terminal propeptide (P1NP), and tartrate-resistant acid phosphatase 5b in the partial correlation analysis adjusted for BMI or T-score in the lumbar vertebrae. We performed a hierarchical multiple regression analysis to identify that serum ALP and P1NP were the independent explanatory variables to %FEV1 independent of other factors. Conclusions The data suggest that the COPD severity in middle-aged and older men with osteoporosis associates with decreased bone formation. COPD patients may exhibit bone metabolism dynamics characterized by low bone turnover with osteogenesis dysfunction as COPD becomes severe.

Objective To analyze the safety and effectiveness of robot-assisted laparoscopic partial nephrectomy(RLPN) for cT2 renal tumors in international multi-centers.Methods This study was conducted to collect information on surgical procedures performed by RLPN and robot assisted laparoscopic radical nephrectomy (RRN) in nineteen international urological centers from January 2012 to December 2017.RLPN were performed in 159 patients (118 males and 41 females),with the average age of (59.3 ± 13.2) years,body mass index(BMI) of (28.7 ± 5.4)kg/m2,preoperative GFR of (77.3 ± 22.1) ml/min.RRN were performed in 219 patients,with the average age of (62.0 ± 12.9) years,BMI of (28.7 ±6.1) kg/m2,preoperative GFR of (71.4 ± 20.3) ml/min.There was no statistical difference between the two groups in gender and BMI.The age of the patients in RLPN group was younger than that in RRN group,and the preoperative GFR was better.The patient's baseline demographics,perioperative data,tumor pathology,oncologic outcomes,and renal function (GFR) were recorded.Results All 378 cases underwent successful surgery.The operation time of RLPN was 150 min(65-353 min),which was shorter than that of RRN [180 min(85-361 min),P ＜ 0.001].The intra-operative blood loss of RLPN was more than that of RRN [150 ml (40-3 000 ml) vs.100 ml (10-1 100 ml),P ＜ 0.001].The incidence of intra-operative complications were not statistically different between the two groups [5.7％ (9/159) vs.3.2％ (7/219),P =0.240].The incidence of postoperative complications was higher in the RLPN group than that in RRN group [19.5％ (31/159) vs.10.5％ (23/219),P =0.014],but there was no significant difference in the incidence of complications of grade 3 or above [4.4％ (7/159) vs.2.3％ (5/219),P =0.246].The recurrence-free survival rate of RLPN group was higher than that of RRN group [91.4％ (117/128) vs.81.9％ (167/204),P =0.013],and RLPN group was more conducive to renal function protection (P ＜ 0.001).Conclusions RLPN for cT2 tumors can obtain effective tumor control rate and better renal function preservation.It could be an acceptable alternative for surgical management of cT2 tumors.

In recent decades, event-related potentials have been used for the clinical electrophysiological assessment of patients with disorders of consciousness (DOCs). In this paper, an oddball paradigm with two types of frequency-deviant stimulus (standard stimuli were pure tones of 1000 Hz; small deviant stimuli were pure tones of 1050 Hz; large deviant stimuli were pure tones of 1200 Hz) was applied to elicit mismatch negativity (MMN) in 30 patients with DOCs diagnosed using the JFK Coma Recovery Scale-Revised (CRS-R). The results showed that the peak amplitudes of MMN elicited by both large and small deviant stimuli were significantly different from baseline. In terms of the spatial properties of MMN, a significant interaction effect between conditions (small and large deviant stimuli) and electrode nodes was centered at the frontocentral area. Furthermore, correlation coefficients were calculated between MMN amplitudes and CRS-R scores for each electrode among all participants to generate topographic maps. Meanwhile, a significant negative correlation between the MMN amplitudes elicited by large deviant stimuli and the CRS-R scores was also found at the frontocentral area. In consequence, our results combine the above spatial properties of MMN in patients with DOCs, and provide a more precise location (frontocentral area) at which to evaluate the correlation between clinical electrophysiological assessment and the level of consciousness.

Objective: To discuss the misdiagnosis of pyriform sinus fistula and to better understand this kind of illness. Methods: The analysis was based on twenty-eight patients with congenital pyriform sinus fistula aged from 11 months to 14 years, with the median age of 5 years, and who were surgically treated from January 2013 to January 2017 in Kunming Children′s Hospital.Twenty patients were misdiagnosed in other hospital.After the routine examination of neck ultrasound and enhanced CT, internal fistula was found by self-retaining laryngoscope, traced by methylene blue, and excised by high ligation. Results: Twenty patients were misdiagnosed.The misdiagnosis time ranged from 6 months to 3 years.Under self-retaining laryngoscope, piriform fossa fistula were found in all patients.Nineteen fistula were found in the left and 1 in the right.The fistula in patients was unilateral.Seven cases were misdiagnosed as suppurative lymphadensitis, undergone abscess incisional drainage many times.Three cases were misdiagnosed as thyroglossal duct cyst and performed excision of thyroglossal duct cyst.One case was treated by extended Sistruck operation again because the doctor considered that excision of middle segment of hyoid bone was not enough and the fistula was not ligated completely.One case was misdiagnosed as second branchial cleft fistula on the right side of the neck.Nine cases were misdiagnosed as hyroid-associated diseases including 2 cases suppurative thyroiditis, 2 cases subacute thyroiditis and 5 cases thyroid neoplasms.Among them, 2 cases underwent partial thyroidectomy.All the patients were treated with high ligation of fistula under general anesthesia.The operation was smooth, and no hoarseness, bucking and pharyngeal fistula occurred after the operation.Postoperative follow-up time ranged from 12 months to 4 years and the median follow-up was 18 months without recurrence.The diagnosis was confirmed pathologically. Conclusions Pyriform sinus fistula in children was uncommon and easily misdiagnosed in clinic.The majority of physician including some otolaryngologists were lack of understanding of the disease.It should be regarded as one of the important differential diagnosis of neck mass in children.Children with recurrent left neck infection and/or abscess should be highly suspected.Self-retaining laryngoscopic examination can make a definite diagnosis and high ligation of the fistula through the external neck approach can achieve good therapeutic effect.

Objective To evaluate pharmacokinetic impact of posaconazole on immunosuppressors.Methods PubMed,EmBase,Cochrane Library Clinicaltrials.gov,CNKI,Wanfang data and CBM were systematica-lly searched.Randomized controlled trials and observational studies which compared combinational use of immunosuppressors and posaconazole were collected.If necessary,Meta-analysis about pharmacokinetic characters of immunosuppressors were performed with RevMan 5.3 software.Results Totally 7 studies were included,involving 258 patients.Two studies of them involving 45 patients related to cyclosporine,3 studies involving 62 patients were using tacrolimus,and 4 studies of 151 patients studied sirolimus,respectively.Overall quality of included studies was low.Concentration/dosage ratio (C/D),AUC,Cmax and t1/2 of cyclosporine when combined with posaconazole were 1.38-told,1.33-fold,1.05-fold and 1.21-fold increase when compared with cyclosporine A monotherapy C/D,AUC,Cmax and t1/2 of tacrotimus were 3.29-fold,4.23-fold,2.14-fold and 1.24-fold increase compared with monotherapy.C/D,AUC,Cmax and t1/2 of sirolimus were 2.71-fold,8.34-fold,6.37-fold and 1.52-fold increase compared with monotherapy.Conclusion Pharmacokinetics of immunosuppressors were changed when combined with posaconazole,therefore dosage should be adjusted according to therapeutic drug monitoring.

Objective To clarify the role of transmembrane protein 66(TMEM66) in intima proliferation of carotid artery induced by balloon injury in rats.Methods SD rats were randomly divided into three groups (n=10), including control group, the left carotid artery balloon injury group and injury group added with lentiviruses, respectively.Accordingly, the intima proliferation of carotid artery were detected by H/E staining;the expressions of TMEM66 in carotid artery injuried by balloon were determined by Western blot,q-PCR and immunohistochemistry, and the migration and proliferation of VSMCs were measured by scratch test and CCK8 respectively.Results Compared with control group, the expression of TMEM66 in carotid artery was obviously decreased after balloon injury (P<0.05).Most importantly, the intima proliferation of carotid artery was significantly reversed by overexpression of TMEM66 via specific lentiviruses (P<0.05).Conclusions TMEM66 is able to attenuate the intima proliferation of carotid artery after balloon injury.It could be that upregulation of TMEM66 can alleviate the migration and proliferation of VSMCs by PDGF.
