ABSTRACT

Objective To compare the clinical efficacy of anti-vascular endothelial growth factor(VEGF)combined with pars plana vitrectomy(PPV)treatment for patients with proliferative diabetic retinopathy(PDR)of different traditional Chinese medicine(TCM)syndrome types in the real world.Methods A prospective real-world study was performed in the 36 patients(involving 42 eyes)with PDR treated by anti-VEGF combined with PPV in the Department of Ophthalmology of the First Affiliated Hospital of Guangzhou University of Chinese Medicine from March 2019 to December 2019.According to the TCM syndrome manifestations,the patients were differentiated as qi-yin deficiency complicated with blood stasis obstructing collaterals type(15 cases,involving 18 eyes;shorten as qi-yin deficiency type),liver-kidney deficiency and ocular collaterals failing in the nourishment type(14 cases,involving 17 eyes;shorten as liver-kidney deficiency type),and yin-yang deficiency complicated with blood stasis and phlegm coagulation type(7 cases,involving 7 eyes;shorten as yin-yang deficiency type).The patients were treated with anti-VEGF therapy first and then received PPV after 5-7 days.Aqueous humor was sampled during anti-VEGF therapy and PPV.After treatment,the efficacy of PDR patients with different TCM syndromes was compared.Moreover,the patients were observed in the best corrected visual acuity(BCVA)of the affected eyes before surgery and 3 months after surgery,levels of cytokines in the aqueous humor before and after anti-VEGF treatment,macular central retinal thickness(CRT),area of the foveal avascular zone(FAZ),the blood density of macular center,inner ring,outer ring and intact macula 3 months after surgery,and the postoperative complications.Results(1)The difference of the therapeutic efficacy of PDR patients with various TCM syndrome types was statistically significant(P<0.05).Among 3 syndrome types,the best efficacy was found in the qi-yin deficiency type,followed by liver-kidney deficiency type,and then yin-yang deficiency type,with the total efficacy rate being 88.89%(16/18),52.94%(9/17),and 42.86%(3/7),respectively.(2)Three months after surgery,the logarithmic value of minimum angle of resolution(LogMAR)for BCVA of patients with qi-yin deficiency type was significantly superior to that of patients with yin-yang deficiency type,with the difference being statistically significant(P<0.05).After the anti-VEGF treatment,the levels of cytokines in the aqueous humor of the patients varied in the 3 syndrome types:vascular endothelial growth factor A(VEGF-A)level in the patients with the 3 syndrome types was significantly lower,placental growth factor(PLGF)and angiopoietin-like protein 4(ANGPTL4)levels in the patients with qi-yin deficiency type were higher,and interleukin 8(IL-8)level in the patients with liver-kidney deficiency type was higher than those before treatment,and the differences were statistically significant(P<0.05 or P<0.01).The blood density of macular outer ring and intact macula in the patients with qi-yin deficiency type and liver-kidney deficiency type was larger than that in the patients with yin-yang deficiency type,and the differences were statistically significant(P<0.05).However,the differences of CRT,FAZ area,and blood density of macular center and inner ring among the 3 syndrome types were not statistically significant(P>0.05).(3)The incidence of postoperative complications in the patients with yin-yang deficiency type was relatively high,but the difference among the 3 syndrome types was not statistically significant(P>0.05).Conclusion In the real world,the best efficacy of anti-VEGF combined with PPV treatment in PDR patients with different TCM syndrome types can be achieved in the patients differentiated as qi-yin deficiency type,followed by liver-kidney deficiency type,and then yin-yang deficiency type.After anti-VEGF treatment,the levels of cytokines in the aqueous humor of the patients vary in the 3 syndrome types.Three months after the operation,the patients with qi-yin deficiency type and liver-kidney deficiency type have larger blood density of macular outer ring and intact macula,and exert good prognosis.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical effects of total hip arthroplasty (THA) for Crowe type IV developmental dysplasia of the hip (DDH) and analyze perioperative complications.</p><p><b>METHODS</b>From March 2000 to March 2010, 19 patients (23 hips, of them, 4 patients with bilateral hips) with Crowe type IV DDH underwent THA. There were 5 males and 14 females, with average age of 61.3 years (ranged, 41 to 72 years). All hips were treated with small acetabular components combined with medial protrusion technique in acetabular reconstruction, as well as subtrochanteric shortening osteotomy in femur. Joint function of hips were evaluated according to Harris scoring.</p><p><b>RESULTS</b>All patients were followed up with an average of 4.2 years (ranged, 1 to 8 years). Postoperative X-ray films showed all acetabular prosthesis were in true acetabulum. No loosening and nonunion were found in all patients. Harris scoring improved from preoperative 34.0 +/- 6.9 to postoperative 85.0 +/- 7.5. Complications occurred in 11 cases in the patients, including femoral split fracture in 3 cases, nerve injury in 3 cases, delayed union in 2 cases, dislocation in 3 cases.</p><p><b>CONCLUSION</b>Total hip arthroplasty using small acetabular component, medial protrusion, femoral subtrochanteric shortening osteotomy technique for the Crowe type IV DDH can effectively restore hip function and leg length. But incidence of complications is high. The long-term follow-up is necessary for further study.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of Bushen Zhuangjin Decoction (BZD) containing serum on the apoptosis of chondrocytes induced by mechanics stimulus.</p><p><b>METHODS</b>The BZD containing serum was extracted. The chondrocyte nutritive media was divided into 3 groups, i.e., the common nutritive medium group, the blank rabbit serum medium group, and the BZD nutritive medium group. The apoptosis of chondrocytes was induced by continuing mechanics stimulus in 24 h. Then the chondrocytes were collected. The apoptosis rate of chondrocytes was determined by flow cytometry. The contents of interleukin 1beta (IL-1beta) and nitric oxide (NO) in the corresponding media were determined.</p><p><b>RESULTS</b>The apoptosis of chondrocytes in the BZD nutritive medium group (19.55 +/- 7.98)% was lower than that of the common nutritive medium group (39.32 +/- 13.45)% and the blank rabbit serum medium group (37.87 +/- 9.67)%, showing statistical difference (P < 0.05). The contents of IL-1beta and NO were also lower in the BZD nutritive medium group with statistical difference when compared with those of the other two groups (P < 0.05).</p><p><b>CONCLUSION</b>BZD containing serum could protect mechanics stimulus induced apoptosis of chondrocytes.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the internal fixation selection and the operative method of Pilon fracture.</p><p><b>METHODS</b>From Aug. 2004 to Aug. 2007,there were 40 patients with Pilon fractures involving 30 males and 10 females. Thirty cases were closed fracture and 10 were open fracture. Seven patients were treated by emergency operation, 3 patients were debrided and suture at first. Twenty-three patients were treated with open reduction and internal fixation (ORIF),the other seventeen patients were treated with LC-DCP,reconstruct plate for fixation or screw, Kirschner wire combine screw for fixation.</p><p><b>RESULTS</b>All patients were followed up for 6 to 32 months (means 19 months). The time of union of fracture was about 3 to 5 months. The outcome was evaluated according to Baired-Jackson criteria, the results were excellent in 27 cases,good in 7, fair in 5, poor in 1. Seven cases were found the operative incision and wound surface difficult to heal,among them 5 cases came from the emergency operation patients, 1 case was closed fracture patient. They were be healed by change of dressing or dermatoplasty or skin flap.</p><p><b>CONCLUSION</b>It is the key factor of treatment for Pilon fractures to correct evaluate before operation and select correct operation time. It is also important to selected suitable internal fixation and good reduction.</p>
