ABSTRACT

Objective:To compare the clinical effects of hip arthroplasty through direct anterior approach (DAA) in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia.Methods:The prospective study method was used to select the patients who needed hip arthroplasty in the Fourth Department of Orthopedics, the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2019. All of them were operated with lateral decubitus DAA. According to the inclusion criteria, they were divided into Kacshin-Beck disease hip osteoarthritis group (group A) and congenital acetabular dysplasia hip osteoarthritis group (group B). Hip Harris score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, visual analogue scale (VAS) score were conducted, and hip abduction angle and flexion angle were measured before surgery, 3, 14 days and 1, 3, and 12 months after surgery.Results:Nineteen and twenty-two patients were included in group A and group B, respectively. All patients successfully completed the surgery. There was no significant difference in Harris score between the two groups before surgery, 3, 14 days, and 1, 12 months after surgery ( P > 0.05). There were no significant differences in WOMAC score, VAS score, hip abduction angle and hip flexion angle between the two groups before surgery and each time point after surgery ( P > 0.05). In the same group, there were significant differences in Harris score, WOMAC score, VAS score, hip abduction angle and hip flexion angle at different time points ( P < 0.001). All postoperative indicators were significantly improved compared with those before surgery. Conclusions:There is no significant difference in the clinical effects of hip arthroplasty through lateral decubitus DAA in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia. This surgical method has good therapeutic effect on both types of hip osteoarthritis.

ABSTRACT

Kashin-Beck disease (KBD) is a disabling osteoarthropathy of unknown cause, which occurs most frequently in children and adolescents and affects many regions in China. In adults KBD patients, the degeneration of weight-bearing joints is the most serious, especially the knee joint. Up to now, there are still a large number of adult patients with KBD arthritis of the knee, and they have not been systematically and effectively treated. The main manifestations are knee joint pain, thickening, deformation and restricted movement. In severe cases, it can lead to knee joint varus, valgus, flexion contracture, and rotational deformity, which seriously affects the quality of life and work ability of the patients. Early diagnosis of KBD arthritis of the knee is difficult and there is no effective treatment, so it needs to be differentiated from knee osteoarthritis (OA). KBD and OA have common pathological characteristics. According to the "Consensus of Four-stepladder Program of Knee 0steoarthritis" (2018), OA treatment is divided into four levels: basic treatment, drug treatment, restorative treatment and reconstruction treatment. In this paper, the treatment of KBD arthritis of adult knee joint is summarized, which is also divided into four steps. It is necessary to make stepwise treatments according to the severity of KBD arthritis of the knee and the differences of patient's own condition, so that the limited medical resources can be efficiently used. At the same time, this paper also systematically summarizes the epidemiological characteristics, pathological features and diagnostic criteria of KBD arthritis of the knee, aiming to provide effective reference and guidance for the treatment of KBD arthritis of the knee.

ABSTRACT

Malignant ovariangerm cell tumors (MOGCTs) is second only to epithelial tumor which often occur in young women and young women,with high malignancy and high mortality.Effective treatment is particularly important in clinical practice.The prognosis is improved for valid chemotherapy scheme foun ded in recent years.Surgery still play a crucial role in the therapy of MOGCTs no matter for the primary operation or re-operation.Since the 70s,the comprehensive surgical staging (CSS) has improved the prognosis in patients with malignant ovarian cell tumors.Retroperitoneal lymphadenectomy is an integral part of the complete staging in MOGCT.The paper discusses various aspects of the clinical value of comprehensive surgical staging in MOGCTs.

ABSTRACT

Objective To investigate the effects of specific methyltransferase inhibitor of 5-Aza-2'-deoxycytidine (5-Aza-CdR) on the promoter methylation of E-cadherin (E-cad) gene, protein expression in human cervical cancer SiHa cells, and the cell biological behavior. Methods SiHa cells were treated with 5-Aza-CdR at different concentrations. Quantitative methylation-specific polymerase chain reaction (QMSP) was used to examine CpG island promoter methylation level of E-cad gene before and after treatment. The experimental group of the optimum concentration was selected. The expression levels of E-cad mRNA and its protein in SiHa cells line were detected by quantitative real-time polymerase chain reaction (RT-PCR) and western blot respectively. Cell adhesion test was used to measure cell adhesion ability and Transwell test was used to detect cell invasion and migration ability. Results E-cad gene promoter methylation index (PMR) of 5-Aza-CdR at 0, 1, 5, 10, 15 μmol/L level was (53.0 ±1.6) %, (50.0 ±1.2) %, (44.0 ±1.4) %, (27.0 ±1.7) %, (15.0±8.2) %respectively, and PMR value decreased gradually with the increase of 5-Aza-CdR concentration. Furthermore, PMR value was the lowest at 15μmol/L, and the difference was statistically significant compared with other 4 groups (P< 0.01). Then 5-Aza-CdR at 15 μmol/L was selected as the following experimental concentration. The expression of E-cad mRNA and its protein in the 5-Aza-CdR group were significantly higher than those in the blank control group (P<0.05). The rates of cell adhesion , cell invasion inhibition and migration inhibition were all increased with significant differences (P<0.05). Conclusions 5-Aza-CdR can upregulate E-cad mRNA and protein expression level in cervical cancer SiHa cells, reduce cell invasion and migration ability, and promote the adhesion of SiHa cells, which has reversed hypermethylation in the promoter region of E-cad gene partly.
