The authors reported 50 cases of neurologic manifestations in 166 patients with systemic lupus erythematoses (SLE), which showed orderly as mental disorders, seizure, headache, optic nerve lesions, cranial nerve palsy, hemiplegia, peripheral neuropathy, myopathy, pseudobulbar palsy, tremor, paraplegia and urinary incontinence. The lesions involved central nerve system, peripheral nerve system and muscular system, one patient might show lesions in more than one part of his body. To diagnose SLE was very difficulty in the early stage of this disease when there were manifestations of nerve system lesion only. When one young woman who has manifestations of nerve lesions was excluded to be ill with other diseases, the possibility of SLE may be considered. The authors reviewed the literature and the pathogencsis of these eomlications and tried to inquire into it further

Objective To explore the correlation of pulse pressure(PP) and outcome in refractory septic shock patients.Methods A total of 68 patients with refractory septic shock consecutively admitted in our ICU from January 2012 to December 2012 were retrospectively studied.Hemodynamic data and arterial lactate concentration were collected at the time of admission and 24 hours after admission.The outcome of Day 28 post-diagnosis was also recorded.Results (1) Compared with the survivors,heart rate(HR) at 24hours after admission was higher in non-survivors,while 24 h lactate clearance rate (rLac) was lower in them (P ＜ 0.05).Other hemodynamic parameters showed no difference between the non-survivors and the survivors at 24 hours after admission,including central venous pressure (CVP),mean arterial pressure (MAP),systolic blood pressure(SBP),diastolic blood pressure(DBP),PP,pulse pressure/heart rate (PP/HR),pulse pressure/mean arterial pressure(PP/MAP),pulse pressure/systolic pressure(PP/SBP),pulse pressure/diastolic pressure (PP/DBP),the value of SBP above MAP (SMP) and the value of DBP below MAP(MDP).(2)The mortality rate was higher in the patients with HR≥100 b/min than those with HR ＜ 100 b/min,but without statistical significance (56.25％ vs 36.11％,P =0.096).Compared with the survivors,no matter with HR≥100 b/min or HR ＜ 100 b/min,lactate(Lac) at the 24 hours after admission was higher in all the non-survivors (P ＜ 0.05),while with lower rLac (P ＜ 0.05).In those with HR ≥100 b/min,the following hemodynamic parameters were higher in the non-survivors than in the survivors,including PP,PP/HR,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (all P values ＜ 0.05),while no statistical difference was observed in those with HR ＜ 100 b/min.(3)The mortality rate showed no statistical difference in those with MAP≥85 mmHg(1 mmHg =0.133 kPa) and with MAP ＜ 85 mmHg(42.42％ vs 48.57％,P =0.611).No matter MAP≥85 mmHg or MAP ＜ 85 mmHg,compared with the survivors,all the non-survivors had higher Lac at the 24 hours after admission (P ＜ 0.05),while with lower rLac (P ＜ 0.05).In those with MAP≥85 mmHg,HR was higher in the non-survivors than the survivors (P ＜ 0.05).In those with MAP ＜ 85 mmHg,compared with the survivors,the non-survivors had higher PP,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (P ＜0.05),while with lower DBP (P ＜0.05).Conclusion PP is correlated with the outcome in refractory septic shock patients.When the HR and MAP differ,PP has different effect on the outcome and contributes more to the tissue perfusion and outcome in those with higher HR and lower MAP.

Objective To detect the effect of low-dose heparin on endothelial function by detecting the change of yon Willebrand factor (vWF) in blood plasma of patients with sepsis shock after treatment with low-dose heparin in order to observe organ function and prognosis of patients.Methods A total of 118 patients with sepsis shock were randomized into low-dose heparin group and control group.In addition to the routine treatment,the patients in low-dose heparin group were given low-dose heparin,while those in control group were not.The levels of APTT,PT,platelet (PLT) count,hepatic function and renal function were determined before and after treatment in two groups,and hemorrhagic events or other complications were recorded.The lengths of stay in ICU and in hospital,the days of mechanical ventilation and the rates of acute respiratory distress syndrome (ARDS),disseminated intravascular coagulation (DIC) and multiple organ dysfunction syndrome (MODS) and 28-day survival rate in the two groups were documented.The levels of vWF in patients of two groups were determined by using immunoturbidimetry before and after treatment.Results The rates of DIC and MODS in low-dose heparin group decreased significantly after therapy (rate of DIC,10.6％ vs.26.7％,P ＜ 0.05;rate of MODS,19.3％ vs.32.0％,P ＜ 0.05).Hepatic function and renal function in low-dose heparin group were significantly improved than that in the control group (P ＜ 0.05),28-day survival rate in the low-dose heparin group was higher than that in the control group (78.3％ vs.69.1％,P ＜0.05),the differences between low-dose heparin group and control group were not statistically significant in the lengths of stay in ICU and hospital,the days of mechanical ventilation and the rate of ARDS (P ＞ 0.05).The differences in APTT,PT and PLT were not significant from pre-treatment to after treatment and between the two groups (P ＞ 0.05).The levels of vWF in low-dose heparin group decreased significantly after therapy rather than those in control group (P ＜ 0.05).Conclusions The endothelial function is improved in patients with sepsis shock after employment of lowdose heparin.Low-dose heparin alleviates the interaction between coagulation and inflammation,improves hepatic,renal and other important organs function,decreases the rate of MODS and increases 28-day survival rate patients with sepsis.The low-dose heparin therapy is a safe and promising treatment in sepsis patients without severe side effects.

Tumor bone metastasis is one of the common complications of advanced tumor and one of the signs of poor prognosis.There are many targeted drugs for bone metastasis in the clinic,which play a very important role in the antitumor treatment and prevention of bone related events.Among them,zoledronic acid,a representative bisphosphonate drug,has been extensively studied.It has been found that zoledronic acid combined with other anti-tumor therapies can more effectively inhibit the occurrence of tumor and bone-related events.This article reviews the latest research on zoledronic acid combined with other antitumor methods to guide clinical use and provide research ideas.

Objective:To investigate the effects of anterolateral wide pedicled double dynamic flap of the calf in repair of soft tissue defects of mid-and forefoot.Methods:From September 2015 to Septemler 2020, 15 cases with severe soft tissue defects of mid-and forefoot were repaired with the anterolateral wide pedicled double dynamic flap of the calf. There were 11 males and 4 females with an average age of 37(range, 22-53)years old. Of the 15 cases, the defects were caused by traffic accident in 6 cases and objects smash in 9 cases. Three cases were simple soft tissue defect, and 12 cases combined with fracture or dislocation and bone defect. The size of soft tissue defects ranged from 4 cm×5 cm to 7 cm×12 cm. All wounds of donor sites were repaired by skin grafting. All patients entered follow-ups at the outpatient clinic or through WeChat. The appearance of flaps and limb recovery were recorded after surgery.Results:All cases followed-up for 6-24 (mean, 16) months. Two days after surgery, 1 case had flap swelling and cyanosis, which was improved after pedicle suture removal and surface bloodletting. The pedicle of the flap was slightly bloated in 4 cases, and the texture and appearance were good in 11 cases. The ankle function of all cases recovered satisfactorily. The ranges of ankle motion were 15°-20° for dorsiflexion and 30°-40° for plantar flexion. The donor site healed well and all the skin grafts survived.Conclusion:The anterolateral wide pedicled double dynamic flap of the calf is one of the ideal flaps for repairing the soft tissue defects of the mid-and forefoot with reliable blood supply, sufficient venous return, simple operation and no require a vascular anastomosis.

Multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), a pathologically similar disease used to model MS in rodents, are typical CD4+ T cell-dominated autoimmune diseases. CD4+ interleukin (IL)17+ T cells (Th17 cells) have been well studied and have shown that they play a critical role in the pathogenesis of MS/EAE. However, studies have suggested that CD8+IL17+ T cells (Tc17 cells) have a similar phenotype and cytokine and transcription factor profiles to those of Th17 cells and have been found to be crucial in the pathogenesis of autoimmune diseases, including MS/EAE, psoriasis, type I diabetes, rheumatoid arthritis, and systemic lupus erythematosus. However, the evidence for this is indirect and insufficient. Therefore, we searched for related publications and attempted to summarize the current knowledge on the role of Tc17 cells in the pathogenesis of MS/EAE, as well as in the pathogenesis of other autoimmune diseases, and to find out whether Tc17 cells or Th17 cells play a more critical role in autoimmune disease, especially in MS and EAE pathogenesis, or whether the interaction between these two cell types plays a critical role in the development of the disease.

Objective:To explore the curative effect of wide pedicled with double-vessel flap of posterior lateral calf in repair of soft tissue defect in hind foot.Methods:From January 2018 to June 2021, 12 patients with soft tissue defects on hind foot were reconstructed with double-vessel flaps pedicled perforator of peroneal artery and sural nerve nutrient vessels in the Department of Trauma Orthopaedics, No.940 Hospital of Chinese People's Liberation Army Joint Service Support Force. The patients were 8 males and 4 females, aged 9-45(27.17±12.14) years old. Time after injury to admission was 6-24(10.17±4.80) hours. Six patients were with simple soft tissue defects, 2 with tendon defects, 3 with bone defects and 1 with postoperative infection due to an open fracture. The sizes of soft tissue defect ranged from 4 cm×5 cm-8 cm×12 cm. Soft tissue defects were reconstructed by transfer of posterolateral calf flaps, and the bone defects were repaired by phase I or phase II bone grafts or antibiotic cement and membrane induction according to the wound surface. For larger bone defects, stage-II bone transport was carried out to restore the length of the hind foot. Defects of Achilles tendon were reconstructed by direct suture or tendon transposition. Foot functions were evaluated by American Orthopaedic Foot and Ankle Surgery(AOFAS) ankle-posterior sufficient scale, visual analogue scale(VSA) score and flap healing. All patients were included in postoperative follow-up regularly through outpatient clinic or via WeChat.Results:All 12 patients had postoperative follow-up that lasted for 6-24(12.92±6.22) months. One flap developed dark purple colour with swelling at the distal end of the flap 3 days after surgery. It eventually healed after removed some sutures from the pedicle together with blood-letting on the flap surface. Three flaps developed local infection, and they were cured after debridement, dressing change and the use of sensitive antibiotics. The remaining 8 patients had achieved good appearance of flaps and normal ankle function. According to AOFAS, scores of ankle-posterior sufficiency scale increased from 14-45(25.25±5.42) before surgery up to 65-96(75.92±7.73) at the final follow-up. Of the 12 patients, 8 were in excellent, 2 in good and 2 in fair. The VAS scores decreased from 5-8(6.55±1.13) before surgery down to 0-4(1.55±1.37) at the final follow-up. The difference had statistics significance( P<0.01). All patients had satisfactory recovery of ankle function, with the extension at 15-20 degrees and plantar flexion of 30-40 degrees. The donor site healed well and all skin grafts survived. Conclusion:The double-vessel flap pedicled with perforating branch of peroneal artery and nutrient vessels of sural nerve can be used for reconstruction of soft tissue defect of hind foot. It achieved good surgical effects with reliable blood supply, smooth venous return, strong anti-infection ability, satisfactory appearance at donor site and flap itself, as well as a good recovery of foot function.

Eight patients with femoral osteomyelitis were admitted in Lanzhou General Hospital of PLA between July 2012 and July 2015. During the operation the femur was fixed with non-contact locking plate after thorough debridement. Iliac morselized cancellous bones without cortical bone were filled in the bone defect after debridement. The locking plates were placed in the lateral subcutaneous interface superficial to the vastus lateralis muscle. Drainage tubes were routinely placed postoperatively. The surgery was completed successfully in all patients, and the average operation time was (130±10) min (120-150 min). Intravenous antibiotics were administrated for 2 weeks and followed by 4 week-oral antibiotics after the operation in all 8 cases. Drainage tubes remained in situ about 8 days. All patients were followed up for 12-48 months, with an average of (19±7) months. Postoperative X-ray examination showed bone union in 7 cases with an average healing time of (16±5) weeks. One patient failed with relapsed infection, and was later treated with Ilizarov apparatus after secondary debridement. No plate and screw fracture, loose and fixation failure were observed in all 8 cases.

OBJECTIVE: To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. METHODS: The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. RESULTS: After the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation ( P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. CONCLUSION Ulnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
