BACKGROUND:Recent studies have shown that the large-dose regular insulin therapy used to control blood glucose levels can cause 50%of patients suffering from vascular, optic nerve and kidney complications. Previous results from authors exhibit that when al ogeneic hematopoietic stem celltransplantation is applied for treatment of leukemia, diabetic symptoms in patients disappear. Dose it prompt that al ogeneic hematopoietic stem celltransplantation is an effective therapy for treatment of diabetes mel itus? OBJECTIVE:To explore the feasibility of hematopoietic stem celltransplantation for treatment of diabetes mel itus. METHODS:A retrospective analysis was done regarding the data of patients with hematological diseases complicated with diabetes mel itus who underwent al ogenetic hematopoietic stem celltransplantation. Four patients with acute lymphocyte leukemia, chronic myelogenous leukemia, aplastic anemia, and myolodysplastic syndromes, respectively, were complicated with diabetes mel itus. Conditioning regimen was cyclophosphamide+total body irradiation protocol. Cyclosporin A and short-term methotrexate were used for graft-versus-host disease prophylaxis. Blood glucose was control ed by oral hypoglycemic drugs or insulin injections before transplantation. RESULTS AND CONCLUSION:Al the four patients were successful y engrafted. Fasting glucose level of the four patients recovered at 4-6 months after hematopoietic stem celltransplantation (without hypoglycemic drugs). One patient died of leukemia relapse after 12 months of hematopoietic stem celltransplantation. The other three patients had disease-free survival until the time of fol ow-up.

ObjectiveTo report our experience and assess the safety and efficacy of ultrasound-guided percutaneous nephrolithotomy (PCNL) with ultrasonic and pneumatic lithotripters for complete renal staghorn stones.MethodsFrom Jan 2006 to Jan 2015, 128 patients (142 kidneys) with complete staghorn stones underwent PCNL, included 14 patients with bilateral renal complete stones,13 patients with solitary or founctional solitary kidney, 22 patients with renal insufficiency, 25 patients with renal empyema, 4 patients with spine malformation, ultrasound-guided PCNL were performed. Stones were fragmented and cleared using a combination of ultrasonic and pneumatic lithotripters.ResultsAll PCNL procedures were successful. Successful access to the collecting system was 100%. Mean operation time was 64.5±39. 1min (range 30–150). The primary stone-free rate of PCNL was 76.8%(109/142). Most of the renal stones(63.4%, 90/142)were managed satisfactorily by a single tract,a second tract was used in 25 renal stones(17.6%, 25/142). There were 36 auxiliary procedures (24 second PCNL and 3 third PCNL and 9 extracorporeal shock wave lithotripsy). One month after treatment, the overall stone-free rate was 85.2%(121/142). Six patients (4.2%) received blood transfusion,three patients(2.1%) received angiography and embolization . Three patients (2.1%) with infective shock were cured by intravenous antibiotics and antishock treatments. Three patients with temporary renal function receded were observed in solitary kidney for two tracts PCNL. No other severe complications occurred. The mean postoperative stay was 5.2 days (range 2–12). Conclusion: Ultrasound-guided Percutaneous Nephrolithotomy with ultrasonic and pneumatic lithotripters for management of renal complete staghorn stones is safe, effective, and worthy of wider use in clinical practice.

BACKGROUND:Zinc-modified calcium silicate (CaSiO3) bioceramics coating on the titanium surface prepared in preliminary experiments has good chemical stability and antibacterial property. OBJECTIVE:To observe the effects of zinc-modified CaSiO3 bioceramics coating on osteointegration. METHODS:MC3T3-E1 cels were respectively cultured on the titanium with zinc-modified CaSiO3 bioceramics coating (experiment group), titanium with CaSiO3 bioceramics coating (control group) and pure titanium (blank control group). Then, cel adhesion, proliferation, calcification rate and the expression of type I colagen and osteocalcin were detected. The implant materials mentioned above were respectively inserted into the femurs of New Zealand white rabbits, and after 1.5 months, the osteoproliferation and osteointegration between the implants and the host were tested. RESULTS AND CONCLUSION:In vitro experiment: The number of adhesive cels at 12 hours after co-culture was significantly increased in the experimental group compared with the control group and blank control group (P < 0.05). At 14 days after co-culture, cel proliferation ability and ability of calcium nodule formation in the experiment group were significantly better than those in the other groups (P < 0.05). At 21 days after co-culture, there was no significant difference in the expression of type I colagen, but the expression of osteocalcin in the experiment group was higher than that in the control group and blank control group (P < 0.05).In vivo experiment: In the experiment group, a large amount of bone substances were detected, the coating materials directly contacted with the bone interface, new bone tissues and little fibrous tissues were observed at the interface. In contrast, there was a small amount of bone hyperplasia in the control group and almost no bone hyperplase in the blank control group. Moreover, a small part of the implant directly contacted with the bone interface and the most part was separated from bone trabeculae by fibrous tissues. These findings indicate that zinc-modified CaSiO3 bioceramics coating can enhance the ability of osteointegration between titanium implants and the host.

OBJECTIVETo determine the classification of masticatory myospasm by analyzing characteristics of clinical appearances.
METHODSThirty-six cases of masticatory myospasm from 2000 to 2010 were included. The clinical data of these patients were analyzed, including patient information, patient history, clinical characteristics, severity and the frequency of myospasmodic movement, electromyogram (EMG), and the efficacy of botulinum toxin injection treatment.
RESULTSThere were 11 males and 25 females, aged from 15 to 71. According to the clinical manifestation and EMG findings, patients could be divided into two groups: 18 cases were classified as jaw closing type which involved masseter and/or temporalis muscles presenting as trismus and acute pain, the other 18 cases were jaw opening type which involved lateral pterygoid muscles complaining difficulty in jaw closing and teeth clenching. The jaw closing type was often seen in patients of 20 to 50 years old, the jaw opening was frequently seen in patients over 50 years old. Jaw closing type was attacked intermittently and unilaterally, but jaw opening was often attacked continually and bilaterally. The rating scale of the severity of spasmodic movement was not different between the two types, but the frequency of spasmodic attack was much higher for jaw opening type (P < 0.05). The EMG of jaw closing type was classified into persistent, rhythmic and irregular type. The EMG of jaw opening type was classified into spontaneous and exercise-induced type. Twelve cases were treated by botulinum toxin injection that could significantly relieve symptoms.
CONCLUSIONSMasticatory myospasm can be classified into jaw closing and jaw opening types. Jaw closing type involves masseter and/or temporalis muscles and jaw opening type involves lateral pterygoid muscles. Botulinum toxin injection was the most effective therapy for the masticatory myospasm.
