Objective To compare the clinical effect for treatment of scapula neck or body fractures by straight incision approach and the Judet approach.Methods From July 2001 to July 2011,32 patients with scapula neck or body fractures were treated using the two different approaches:(1) the straight incision approach in 15 patients including 11 males and 4 females,the average age of 38.10 years,fractures classified by Ada-Miller including 4 ⅡA,6 ⅡB and 5 Ⅳ; (2) the Judet approach in 17 patients including 12 males and 5 females,the average age of 39.47 years,fractures classified by Ada-Miller including 5 ⅡA,4 ⅡB and 8 Ⅳ.All patients were followed up.Intraoperative data and postoperative pain of two groups were compared by visual analogue score (VAS),the efficacy were evaluated by Rowe-Zarins scores and the patient's postoperative shoulder function were assessed by Constant-Murley functional score.Results All fractures were preliminary healed after 8 weeks of surgery,there was no wound infection,no internal fixation loosening,no shoulder deformity and other complication.Length of incision,operative time and blood loss of straight incision approach was 6.73±0.96 cm,58.67±4.39 min,94.25±6.14 ml and length of incision,operative time and blood loss of Judet approach was 18.88±1.41 cm,82.24±4.49 min,227.77±23.08 ml.VAS of straight incision approach and Judet approach were 2.60±1.55 and 4.65±1.93,mild and moderate postoperative pain evaluated by VAS were significant differences between two groups.The excellent rate by Rowe-Zarins scores of straight incision approach and Judet approach were 93.3％(14/15) and 88.2％(15/17),they were no significant differences.There was no significant differences in the shoulder joint mobility and muscle strength of Constant-Murley functional score between two groups.However,pain and daily life of Constant-Murley functional score were significant differences between two groups and Constant-Murley functional score of straight incision approach and Judet approach were 85.60±3.31 and 80.65±3.44.Conclusion Compared with Judet approach,straight in cision approach has many advantages,such as a short time of surgery,minor injury,light postoperative pain,good postoperative functional recovery.It is the better surgical approach for the treatment of scapular fractures.

BACKGROUND:Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cellcycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as wel as the expression of endothelial cells related cytokines. OBJECTIVE:To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cellsecreted cytokine markers. METHODS:Morphological changes of PBMCs separated from normal karyotype human peripheral blood individual y cultured with or without PHA were observed. The PBMCs were col ected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cellproliferation, apoptosis, and expression of inflammatory cytokine and endothelial cellsecreted cytokines. The statistic analysis was used for the significance explication. RESULTS AND CONCLUSION:PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cellnuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-βand interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.

OBJECTIVETo explore the clinical efficacy of the arthroscopic Mender II stapler for the treatment of patients with meniscus anterior horn injury needing meniscal suture repair.

METHODSAmong 47 patients with meniscus anterior horn injury, 29 patients were male and 18 patients were female, ranging in age from 12 to 31 years old, with a mean age of (20.53± 4.12) years old. The duration of disease ranged from 3 to 35 days, and the average duration was (12.43±5.74) days. The Mender II stapler was used to carry out arthroscopic suture from outside to inside. The Lysholm knee scoring system was used to evaluate and analyze preoperative and postoperative symptoms, such as pain, limping embolism and so on.

RESULTSForty-six patients were followed up, and the duration ranged from 12 to 48 months, with a mean of (20.53±4.12) years. The incision healed at the first stage without important vessels and nerves injuries. The symptoms of the locked knee joint disappeared, and symptoms such as pain, limp, swelling and limitation of activity improved. The Lysholm score increased from preoperative 52.33±7.31 to postoperative 86.74±6.92.

CONCLUSIONUsing Mender II stapler to treat patients with meniscus anterior horn injury who were treated with arthroscopic suture from outside to inside is effective to improve symptoms, and to obtain good short-term results.

OBJECTIVETo explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation.

METHODSFrom January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group. In shoulder pain group, there were 21 cases including 15 males and and 6 females ranging the age from 22 to 62 years old with an average of (40.6±11.2) years old. There were 8 cases were on the left side and 13 cases were on the right side. In painless group, there were 65 cases including 36 males and and 29 females ranging the age from 19 to 65 years old with an average of (40.0±11.3) years old. There were 33 cases were on the left side and 32 cases were on the right side. The time from injury to operation ranged from 3 h to 8 d with an average of 34.6 h. Shoulder function of all patients were normal before injuried. Postoperative pain, activity of daily living (ADL), range of motion, deltoid muscle strength were compared. Anteflexion,rear protraction, abduction and upthrow of shoulder joint were also compared. Postoperative complications between two groups were observed and compared.

RESULTSAll patients were followed up from 12 to 48 months with an average of 18.5 months. Constant-Murley score were used to evaluate clinical efficacy at the least following up, and 13 cases got an excellent results, 5 moderate, 2 good and 1 poor in shoulder pain group ; while 61 cases were obtained excellent results, 3 moderate and 1 good in painless group. There were significantly differences between two groups in Constant-Murley score and activity of shoulder joint (P<0.05). In shoulder pain group, 3 cases were disconnected, 1 case occurred stress fracture, 9 cases were subacromial impingement syndrome, 5 cases occurred subluxation, 1 case occurred plate breakage and 11 cases were acromioclavicular arthritis.

CONCLUSIONChosing individual clavicular hook plate, fulfilling anatomic reset, paying attention to the repair of articular capsule ligament, and reducing hook and bone antagonism between stress is the key point of preventing and decreasing postoperative shoulder pain.

BACKGROUND: It is necessary to establish a high throughput screening system for anti -inflammatory drugs for rheumatoid arthritis.OBJECTIVE: To construct an eukaryotic expression vector p4CCL20-ZsGreen1-DR with the NF-kB cis-acting element 4×CCL20motif as an enhancer, SV40 as a promoter, and ZsGreen1-DR as a reporter gene.METHODS: The target fragment SV40 was PCR amplified using PGL2-control plasmid as a template. KpnⅠ/Bam HⅠ restriction sites were introduced into the flank of the target fragment. Then, pSV40-ZsGreen1-DR vector was constructed by cloning the target fragment into pZsGreen1-DR plasmid. Finally, p4CCL20-ZsGreen1-DR plasmid was constructed by cloning the double strand DNA of 4×CCL20 motif (with BglⅡ and EcoRⅠ sticky ends at the 5’ and 3’ terminus, respectively) into the corresponding restriction sites of pSV40-ZsGreen1-DR vector (upstream of SV40 promoter).RESULTS AND CONCLUSION: DNA sequencing demonstrated successful construction of p4CCL20-ZsGreen1-DR plasmid.The construction of p4CCL20-ZsGreeR plasmid might be useful to establish a high throughput screening system for anti -inflammatory drugs.

Objective To unravel the relationship between Toll-like receptor 4 (TLR4) expression in platelets and the activation of platelet in thrombocytopenia (TCP) in case of sepsis. Method A total of 64 patients with sepsis were prospectively studied with control. Platelet count (PC), mean platelet volume (MPV),platelet distribution width (PDW),platelet TLR4 expression, platelet PAC-1 expression, sCD40L and TNF-α concentrations were compared between healthy control group (15 cases) and sepsis group on admission and 3 d,Sd,and 9 days after admission. The changes of MPV and PDW in TCP and non-TCP subgroups of sepsis before and after treatment were recorded. Prognostic index was analyzed. Results The PC was lower in sepsis group (P=0.006), and MPV and PDW were higher in sepsis group than those in healthy control group (P = 0.046, P =0.001). Platelet TLR4 and PAC-1 expressions, and sCD40L and TNF-α levels also increased more significantly in sepsis group (P ＜ 0.001). PAC-1 expression and TNF- level were higher in TCP group than those in non-TCP group before and after treatment (P = 0.023, P = 0.011). The sCD40L concentration and platelet TLR4 expression were significantly higher in treated TCP groups than in non-TCP group (P = 0.047, P = 0.001). Compared with non-TCP,the rate of bleeding was higher (P = 0.024) and the length of ICU stay was longer (P = 0.013).The APACHE Ⅱ score and the 28-day mortality were higher in TCP group (P ＜ 0.01, P = 0.048). Conclusions The elevation of platelet TLR4 expression in sepsis along with platelet activation is closely related to the incidence of thrombocytopenia. The occurrence of TCP is a poor prognosis sign of sepsis.
