OBJECTIVETo evaluate the clinical results of the medial patellofemoral ligament (MPFL) reconstruction combined with the lateral retinacular release for the treatment of recurrent patellar dislocation.

METHODSFrom March 2011 to June 2013, 15 patients with recurrent patellar dislocation underwent arthroscopic MPFL reconstruction combined with the lateral retinacular release. The graft was autogenous semitendinosus and semimembranosus tendon. There were 5 males and 10 females with an average age of 19.4 years old (ranged,14 to 32 years old). The patients suffered recurrent patellar dislocation at least twice preoperatively. Preoperative conventional X-ray, CT, and MR examination were used to analyze the causes of the patellofemoral joint and MPFL injury. Preoperative Lysholm score was 69.85 ± 11.52. During operation, the arthroscopic examination was performed to evaluate the patellofemoral alignment and patellar tracking.

RESULTSAll the patients were followed up for an average of 27.6 months (ranged,12 to 36 months) with no recurrent dislocation and sub-dislocation. All the patients showed negative apprehension test at straight and 30 ° flexions of knee. The range of motion of knee returned to normal level at 12 months after operation. There were no patients with subjective discomfort of knee. Postoperative Lysholm score was improved to 92.60 ± 5.75.

CONCLUSIONThe technique of arthroscopic MPFL reconstruction combined with the lateral retinacular release is an effective surgical procedure for the treatment of recurrent patellar dislocation, which can relieve the symptom of knee and improve the patella stability and knee function.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

[Objective]To explore the relationship between peripheral arterial disease(PAD)and diabetic retinopathy(DR)in type 2 diabetes patients.[Methods]A total of 99 patients diagnosed with PAD were classified into grade 1-3 by their total scores of peripheral arterial stenosis assessed by color doppler ultrasound examinations,where the degree of stenosis 30% ~ 49% scored 0, 50%~99%scored 1,lumen occlusion(i.e. degree of stenosis 100%)scored 2,and therefore the total score 0-2 was categorized into Grade 1 ,3~4 into Grade 2 ,5~12 into Grade 3. The bilateral anterior tibial artery ,posterior tibial artery and dorsalis pedis artery of these patients were analyzed. The presence of diabetic retinopathy(DR)was graded from retinal photographs using a standard protocol.[Results]Among 99 cases of type 2 diabetic patients with peripheral arterial disease ,58.6%of them were male with average age of 67.3 ± 7.9 years old. Patients of Grade 1,Grade2,Grade 3 lesion accounted for 45.4%,30.3%,24.2%,respectively. Age, gender,smoking history,SBP,DBP,BMI,FBG,TC,TG,LDL-C,HDL-C,HbA1C among 3 groups were not statistically signifi-cant. The associations of DM duration and HbA1C value were significantly larger in DR than in PAD. The proportion of DR patients increased with the severity degree of PAD(p for trend=0.004). Degree of stenosis Grade 2 and Grade 3 could be predictive for DR.[Conclusions]DR is associated with the severity degree of PAD in type 2 diabetes patients as evaluated by duplex ultrasonography.Degree of stenosis Grade 2 and 3 could be used for screening or finding DR. Strategies for optimum treatment and early prevention are needed.

A nest RT-PCR/restriction test has been developed in order to distinguish the lapinised vaccine strain from field isolates of classical swine fever virus. The restriction enzyme cut sites mapping of the major coding sequence of E2 gene lapinised vaccine strain and ShiMen strain of classical swine fever virus have been compared. Ten and sixteen unique restriction markers have been found in the lapinised vaccine strain and ShiMen strain. The restriction enzyme cut sites mapping of the twenty six unique restriction marker in the major coding sequence of E2 gene of 17 classical swine fever field isolates have been analyzed. Only 3 sites (HgaI、Hin8I及Hsp92I) are present in the lapinised vaccine strain sequence. Two pans of nested primers and a criteria of analysis have been designed for HgaI restriction marker site. The tests have been conducted first on the lapinised vaccine strain and ShiMen strain of classical swine fever virus resulting in predicted restrection patterns. Finally, the tests have been applied to 5 field isolates of different gene group analyzed by phylogenetic study. The result showed that only HCLV strain gene can be cut to 2 fragment by Hgal , and ShiMen strain and 5 field isolates cant be cut At the same time the sensitivity and specificity of nest RT-PCR have been tested. The sensitivity is 0. 2MLD. The specific fragment of BDV and BVDV were not obtained by the nest RT-PCR. These results showed that the development of the nest RT-PCR/restriction tests is very important for the control and perish of classical swine fever in china.

BACKGROUND:In the treatment of tibial plateau fractures, because of the variety of fracture, the complexity of anatomical changes, X-ray films or three-dimensional CT scan limited by two-dimensional plane, increases the difficulty in preoperative plan and surgical treatment. The application of three-dimensional (3D) printing technology has attracted attention in the department of orthopedics. OBJECTIVE:To explore the auxiliary role of 3D printing technique in preoperative plan and treatment for tibial plateau fractures. METHODS:Thirty patients with tibial plateau comminuted fractures were enroled in this study and divided into two groups: experimental and control groups, with 15 patients in each group. In the experimental group, patients underwent 3D CT scan, which was stored in DICOM format, and processed by Mimics software. Data were converted into STL format, entered 3D printer, and a 1:1 entity size of the fracture model was made, in accordance with repair plan of 3D fracture model. Operation time and intraoperative blood loss were compared between the two groups. At 12 months after treatment, their outcomes were assessed using Rasmussen evaluation criteria. RESULTS AND CONCLUSION: The 3D printing fracture models of 1:1 ratio identified fracture type and made a repair program before surgery in the experimental group. Operation time and intraoperative blood loss were significantly less in the experimental group than in the control group (P < 0.05). After surgery, patients were folowed up for 12 to 18 months. The healing time was 3-5 months, averagely 4.3 months. At 12 months after treatment, the Rasmussen evaluation criteria results showed that the excelent and good rate was significantly higher in the experimental group than in the control group (P < 0.05). These results suggest that the fracture model of 3D can help to make the operation plan. The treatment of tibial plateau fractures is more precise, personalized and visual.
