Objective To observe the clinical outcomes of modified posteromedial and posterolateral approaches for the treatment of posterior tibial plateau fractures.Methods Between January 2006 and October 2011,25 patients with posterior tibial plateau fracture were identified.They were 17 men and 8 women,aged from 22 to 76 years (average,46.4 years).According to the AO/OTA classification,there were 4 cases of type 41-B1,6 cases of type 41-B2 and 15 cases of type 41-B3.According to Luo's three-column classification,they were all posterior column fractures.Ten patients with posterolateral tibial plateau fracture were treated by the modified posterolateral approach and the other 15 patients with posteromedial tibial plateau fracture by the modified posteromedial approach.The posterior fractures were fixated with a buttress plate.The knee function was evaluated at the last follow-up by the The Hospital for Special Surgery (HSS) Score.Results All the 25 cases were followed up for a mean time of 13.2 months (from 10 to 24 months).By the radiological Rasmussen criteria for fracture reduction,the mean score immediately after surgery was 16.5 points (from 13 to 18 points),with 20 excellent cases,4 good cases and one fair case.All patients were pain-free with full range of motion.Radiologically,bone union was achieved in all cases after a mean time of 13.9 weeks (from 12 to 18 weeks).No surgery-related complications were found.The mean HSS score was 91 points(range,74 to 97 points) and the good to excellent rate was 100％ (17 excellent and 8 good cases) at the last follow-up.The average range of knee motion ranged from 0° to 125°.Conclusion In the treatment of posterior tibial plateau fractures,because the modified posteromedial and posterolateral approaches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating,soft tissues can be well preserved and good functional results can be expected.

Objective:To test the reliability and validity of Urban empty-nesters Home Safety Risk Factor Assessment Scale (Uen-HAS), in order to provide an instrument for assessing the safety risk factors of urban empty-nesters.Methods:Totally 530 urban empty-nesters from Fuzhou City, Fujian Province were employed by convenient sampling method for household survey, from August to October 2018. Item analysis and validity and reliability test were conducted.Results:The final version of urban empty nest elderly home safety risk factor assessment scale (Uen-HAS) contains 5 scales, 12 sub-scales and 55 items. The Cronbach α coefficient of the scale was 0.896. The content validity index (S-CVI) of the total scale was 0.881. The correlations of the scores between each item and the total scale ranged from 0.509 to 0.812 with statistical significance ( P<0.05). Conclusion:The scale has good reliability and validity. It could be an instrument to access safety risk factors of urban empty nesters.

Objective To eonstruct three eukaryotic expression vectors containing wilde-type hGHR gene and its mutants(hGHR-E42K and hGHR-H56R) related to congenital growth hormone insensitivity, then check their expression in CHO cells. Methods With the available PUC-hGHR vector, two mutate hGHR genes (hGHR-E42K and hGHR-H56R) were obtained through mutagenesis. Then three recombinants were cloned into eukaryotic expression vectors pcDNA3.1/zeo(+) with restriction enzymatic reactions.Then with Lipofectamine2000, we trans-fected expression vectors to CHO cells and screened the stably expressed CHO cells by Zeocin. RT-PCR and/or Western blotting were used to examine hGHR and STAT5-P. Results After sequencing, two mutations were introduced to hGHR, three eukaryotic expression vectors were identified. The transfected CHO cells expressed vd-hGHR or its mutants. Compared with hGH-wt, two mutate cells (E42K and H56R) had decreased phosphorylated STAT5 levels. Conclusion Three CHO cells which stably expresses wide type hGHR and its mutants were successfully established, E42K and H56R partly interfered the phosphorylation of STAT5.

Objective To discuss the clinical value of application of three-dimensional reconstruction technique of MSCT in examination of colonic tumours.Methods Thirty patients underwent scanning using helical CT and post-processing on the workstation.All CTC images were reconstructed using shaded surface display (SSD) on workstation.Perspestive images such as the ones from DCBE were generated via raysum.The images could clearly demonstrate the extent and detail of the disorder by adjusting the CT value threshold.These results and that of barium enema and colon endoscopy were compared.Results Thirty cases had completely clinical and pathological data.3D images could correctly reveal the macroscopic morphology of colon tract and location of lesions.The correctly diagnostic rate was 100％ by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion With the utilization of multiple methods,3D reconstruction can effectively demonstrate colonic tumours,and can be applied routinely in examination of colonic tumours.

OBJECTIVE:To study the clinical characteristics and related of the adverse drug reactions(ADR) induced by carbamazepine,and propose preventive solutions.METHODS: 102 cases of carbamazepine-induced ADR,reported in medical journals of China from January 2001 to December 2005,were collected and analyzed.RESULTS:Skin and its appendages received most impairment from carbamazepine-induced adverse reactions(representing 35.3%),followed by general impairment of the body and impairment of the blood & hematopoietic system.Combined use of drugs is liable to induce adverse reactions,indicated by the fact that 16.7% of the sufferers received treatment by combined use of multiple drugs.Most of the ADR occurred 1h after administration.CONCLUSION:Individual differences of patients and combined use of drugs are among the factors that result in carbamazepine-induced adverse reactions.

OBJECTIVE:To discuss the influencing factors of anticoagulation with warfarin in patients who had undergone artificial mechanical heart valve replacement and the relation between dosage regimens and international normalized ratio(INR).METHODS:123 patients who had undergone artificial valve replacement patients were followed-up.The patients were treated with warfarin therapy for anticoagulation after surgery,and given a regular follow-up.Patients' age,gender,and INR value etc were recorded and the adverse events including bleeding,embolism and death were observed.RESULTS:No death case was reported;femoral vein thrombosis occurred in 1 case;gingival bleeding occurred in 11 cases and urinary tract bleeding was noted in 3 case.The incidence of anticoagulation-associated ADR was close to that reported in overseas literature.CONCLUSION:According to INR,individual dose of warfarin should be administered on day 5 after artificial valve replacement.Maintaning INR at 1.5～2.0 can achieve certain anticoagulation efficacy and is relatively safe.

In traditional oral practice, the presystemic interactions with gut microbiota is an important mechanism underlying the holistic health benefits of Chinese herbal medicines (CHMs), making the study of CHMs distinct from the research of Western medicines of which the systemic exposure (level in blood) is the starting point and the core. Gut microbial metabolism complements host metabolism in maintaining metabolic homeostasis of many biologically important endogenous molecules and the disposition of numerous exogenous compounds. Among them, the widely distributed gut bacterial β-glucuronidases (BGUSs) coordinate with host UDP-glucuronosyltransferases (UGTs) to play a role in the occurrence and intervention of diseases by affecting the glucuronidation homeostasis and altering the intestinal local and/or systemic exposure of endogenous compounds and xenobiotics. On one hand, many ingredients of CHMs undergo enterohepatic circulation; On the other hand, CHMs can act on BGUSs directly or indirectly change the distribution and function of BGUSs through reprogramming gut microbiome. The multiple interactions between BGUSs and CHMs may play an important role in the overall therapeutic benefits of CHMs. This work firstly summarizes the latest research progress on BGUSs; then the physiological, pathological and pharmacological significance of BGUSs are exemplified with representative endogenous and exogenous compounds from the aspects of nutrient utilization, metabolic homeostasis, and therapeutic response based on the varied substrate spectra of BGUSs; finally, the scattered data in literature were integrated to summarize the multiple interactions between BGUSs and CHMs, highlighting the important role of BGUSs in the holistic actions of CHMs.
