AIM: To investigate the role of fibrocystin/polycystin (FPC) in autosomal recessive polycystic kidney disease (ARPKD) development by means of screening the protein interaction using yeast two-hybrid approach. METHODS: The constructed pGBKT7-FPC was used as the bait to screen the pre-transformed human fetal kidney cDNA expression library by yeast two-hybrid assay to obtain the host cell protein which interacted with C-terminal region of FPC. The sequence transformation screening experiment was applied to confirm the protein interactions in yeast. RESULTS: After yeast mating and co-transformation screening analysis, Klotho (KL) was selected from the host cells and the interaction between KL and FPC was further confirmed. CONCLUSION: C-terminal region of FPC can interact with KL, which probably provide the approach for further studying the role and biochemistry mechanism of FPC protein in ARPKD.

Objective To explore frequency distribution of vitamin D receptor (VDR) genotype and the correlations between polymorphism of VDR gene Bsm Ⅰ sites and bone mineral density in the patients undergoing maintenance peritoneal dialysis.Methods A case-control study was conducted based on 82 patients with maintenance peritoneal dialysis and 80 healthy people.The frequency distribution of VDR genotype in two groups was detected and analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).Serum biochemistry and bone mineral density of the patients undergoing maintenance peritoneal dialysis were detected by dual energy X-ray absorption (DEXA) and automatic biochemical analyzer,respectively.All data was analyzed with SPSS 19.0 software.Results The frequency distribution of VDR genotype between case group and control group had no significant difference (P ＞ 0.05).The serum biochemical index such as Ca,P,alkaline phosphatase (ALP) and parathyroid hormone (PTH)] of patients with maintenance peritoneal dialysis had no significant difference among three VDR genotypes(P ＞0.05).Compared to VDR bb genotype,the serum Ca was significantly higher in VDR BB genotype (P ＜0.05).The bone mineral density (BMD) and T-Score of patients with VDR BB genotype were the lowest,the BB genotype was the highest,and the difference was statistically significant among three genotypes (P ＜0.05).Conclusions The frequency distribution of VDR genotype between case group and control group had no significant difference.However,there is a correlation between VDR gene BsmⅠ sites and bone mineral density of maintenance peritoneal dialysis patients.

Objective To evaluate the role of the sodium removal and explore the relationship of sodium balance and blood pressure in patients with traditional hemodialysis.Methods Fourteen patients with maintenance hemodialysis were randomly enrolled in this study.Serum sodium concentration was measured at the pre-dialysis and post-dialysis.At the beginning of dialysis and every half hour,20 ml waste dialysates were collected,10 ml were drown from total 180 ml waste dialysates that had being mingled for measuring total NaCl removal and the removal caused by ultrafiltration.The Fisher's Exact Test was used to analyze the difference in incidence of hypertension(≥ 150/90 mmHg group or ＜ 150/90 mmHg) between the different NaCl removal groups.Results The total NaCl removal in single hemodialysis session was (29 ±14.9)g,A average of (18 ± 6.9)g sodium was removed by ultrafiltation (83 ± 58.6)％.The patients whose sodium removal in a hemodialysis session were less than 29 g,which were vulnerable to hypertension (≥ 150/90 mmHg group) (P =0.023).Conclusions The factors that effected sodium removal in hemodialysis session were complicated; most of sodium was removed by ultrafiltration of plasma water.These results demonstrated that adequate ultrafiltration volume in triple times a week rather than restriction of fluid intake was the principal factor that controls blood pressure in patients with traditional hemodialysis.

BACKGROUND: Wenyang Yisui Recipe is developed based on Yougui Pills according to many years of clinical practice. The clinical application of Wenyang Yisui Recipe in the treatment of early knee osteoarthritis as a prophylactic and therapeutic treatment has achieved favorable clinical effect. OBJECTIVE: To investigate the clinical efficacy of Wenyang Yisui Recipe combined with arthroscopic osteochondral autografts in the treatment of cartilage lesions of the knee. METHODS: Eighty-three patients under arthroscopic osteochondral autografts for cartilage lesions of the knee were enrolled, including 49 males and 34 females, aged 40 to 67 years old, with an average of (50.2±4.8) years old. The course of disease ranged from 1 to 27 months, with an average of (12.3±5.2) months. According to the Doll’s method, all the patients were divided into study group and control group. The patients in the study group received arthroscopic osteochondral autografts, followed by oral Wenyang Yisui Recipe, 300 mL per day in two divided doses, beginning at 2 days postoperatively for 2 continuous weeks as a session, three sessions in total. The control group only undertook arthroscopic osteochondral autografts. The Lysholm score and visual analogue scale score were used for assessing the knee function and pain, respectively, before surgery and 3 months after surgery. The study protocol was implemented in line with the relevant ethical requirements of Wang Jing Hospital, China Academy of Chinese Medical Sciences in February 2014 (approval No. 221). RESULTS AND CONCLUSION: All patients were followed up for 3 months after surgery. The study group was superior to the control group in the improvement of knee joint pain and swelling score at 3 months after surgery, and the intergroup difference was statistically significant (P < 0.05). The visual analogue scale score was significantly better in the study group than the control group at 3 months after surgery (P < 0.001). The visual analogue scale scores in the two groups were both improved at 3 months after surgery (P < 0.001). Therefore, arthroscopic osteochondral autografts combined with oral Wenyang Yisui Recipe can significantly ameliorate knee pain and function, with definite clinical effects.

The clinical data of a child with perianal necrotizing fasciitis admitted to the Department of Pedia-trics of Guangzhou First People′s Hospital were retrospectively analyzed.The child, girl, more than 5 months old, the clinical features of the onset of fever and diarrhea, only 10 days after the onset, the child′s skin progressed from redness and swelling to perianal skin and soft tissue ulcers, fat liquefaction, visible rectum exposure.After surgical incision, thorough debridement and drainage and selection of sensitive antibiotics, the child recovered and was discharged.Perianal necrotizing fasciitis is a rare necrotizing soft tissue infection caused by a variety of bacterial infections.Because its early performance is difficult to distinguish, the symptoms are serious, and the mortality rate is high.It should been pain attention in clinical work.

Objective:To evaluate effect of addition and subtraction therapy of Buyang Huanwutang combined with Si Junzitang and acupuncture to poststroke fatigue （PSF） and syndrome of Qi deficiency and blood stasis， at the same time we studied the antioxidant and anti-inflammatory effects. Method:One hundred and forty-four patients were randomly divided into control group and observation group （1∶1） by random number table. 66 patients in control group completed the therapy （4 patients were falling off or missing visit， 2 patients were eliminate）， 67 patients in observation group completed the therapy （2 patients were falling off or missing visit， 3 patients were eliminate）. In control group， patinets got acupuncture， 1 time/day， 6 times/week， they also got Geqi Tongmai grain， 10 g/time， 3 times/day. Patients in observation group got acupuncture （the same as which in control group）， and addition and subtraction therapy of Buyang Huanwutang combined with Si Junzitang， 1 dose/day， and courses of treatment in two groups were 4 weeks. Before and after treatment， fatigue severity scale （FSS）， NIH stroke scale （NIHSS）， syndrome of Qi deficiency and blood stasis， stroke specific quality of life scale （SS-QOL）， and scores of ability of daily life （ADL） were recorded. And levels of superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， homocysteine （Hcy）， interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α） and C-reactive protein （CRP） were detected. And the safety evaluated. Result:Disease effect in observation group was better than which in control group （Z=2.118， P<0.05）. And effect after using traditional Chinese medicine （TCM） was also better than that in control group （Z=2.046， P<0.05）. Scores of FSS， syndrome of Qi deficiency and blood stasis， NIHSS， and levels of IL-1β， IL-6， Hcy， CRP， TNF-α and MDA in observation group were all lower than those in control group （P<0.01）， and scores of SS-QOL， ADL， and levels of GSH-Px and SOD were all higher than those in control group （P<0.01）. Then there was no related safety issues caused by drug. Conclusion:Addition and subtraction therapy of Buyang Huanwutang combined with Si Junzitang and acupuncture had effect of anti-oxidation and anti-inflammatory， and can significantly reduce fatigue and degree of neurological impairment and can improve patients' quality of life and daily life ability. The clinical effect is significant and safe， which is worthy of further research and application.
