This study was to describe the use of inverted-L osteotomy of ramus and iliac bone graft for the management of mandibular deficiency in adult patients. From 2008 to 2010, 11 patients (aged 19 to 29 years) with mandibular deficiency underwent intraoral or extraoral inverted-L osteotomy of ramus and iliac crest bone grafting. Data were collected from the patients' records, photographs and radiographs. The height and width of the ramus were successfully expanded by inverted-L osteotomy and iliac crest bone grafting with minimal complications in all patients, resulting in significant improvement in occlusion and facial appearance. Our early results showed that the inverted-L osteotomy of ramus and iliac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular deficiency.

OBJECTIVETo analyze the transcription activation and possible regulation mechanism of human X-box binding protein 1(XBP1)gene 5'upstream DNA sequence in different cell lines.

METHODSSix kinds of XBP1 promoter deletion mutants were cloned into pGEM-Teasy vector, which included XBP1 gene 5' upstream -1039 to 66 bp,-859 to 66 bp,-623 to 66 bp,-351 to 66 bp,-227 to 66 bp,-227 to -45 bp respectively. Every deletion mutant sequence was cut from Teasy-XBP1p by KpnI and Xho I, and subcloned into pCAT3-Basic to produce a set of constructs termed as p1-XBP1p, p2-XBP1p, p3-XBP1p, p4-XBP1p, p5-XBP1p, p6-XBP1p, respectively. The transcription activity of each construct was detected after transiently transfecting K562, HepG2,NIH-3T3 and L0(2)cell with FuGENE 6 transfection reagent. Cells transfected by pCAT3-Basic or pCAT3-Promoter were used as negative and positive controls. The activity of chloramphenicol acetyltransferase(CAT), which reflects the transcription activation of the XBP1 gene promoter, was detected by ELISA after 48 hours of transfection.

RESULTSThe reporter vectors of six kinds of XBP1 promoter deletion mutants were successfully constructed, as confirmed by restriction enzyme digestion and sequencing. The activities of p4-XBP1p and p5-XBP1p were higher than the other deletion mutants in K562 and HepG2. And the activity of p5-XBP1p was the highest in HepG2. There was no activity detected from any transfected NIH-3T3.

CONCLUSIONThe XBP1 gene promoter can transactivate its downstream gene to transcription. The core sequence of XBP1 promoter was implied between -227 bp and 66 bp. This sequence was connected with the transcriptional activity of XBP1 promoter closely. Its transcription activity varies with different cell lines. XBP1 promoter might drive gene expression with cell-type specificity.

OBJECTIVETo identify the side effect of all-trans retinoic acid (ATRA), and improve early therapeutic response in patients with acute promyelocytic leukemia (APL).

METHODThe first case of Sweet's syndrome (SS) developed in a APL patient treated with ATRA was reported in mainland of China, and reviewed correlative literature.

RESULTSOnly 14 cases of SS associated with ATRA therapy in APL have been reported in the literature, including the present case. The median age was 49.5 years (9 -84) and 10 were women and 4 men. Of them, SS was restricted to the skin in 10 case, the other 4 muscle, fascia, kidney, and lung were involved. SS appeared after a median of 18 days of ATRA therapy (6 - 34 days). The median WBC count was 7.05 (0.80 - 23.00) x 10(9)/L. Four patients continued with the ATRA therapy without interruption, 13 patients treated with steroids and 12 responded. One patient improved without any treatment. Two cases of SS developed retinoic acid syndromes after ATRA therapy.

CONCLUSIONSweet's syndrome is a rare adverse effect of ATRA, and has similar features with inflammatory or infective dermatosis. The corticosteroids treatment could improve the systemic and cutaneous symptoms. When ATRA therapy was restarted after SS subsided, no recurrence of rashes was observed.

OBJECTIVETo study the therapeutic effect of Weicao Capsule (WCC) on gout.

METHODSTwo hundred gout patients were assigned to two groups. The treated group was treated with WCC and the control group was treated with Tongfengding Capsule. Both groups were given the respective treatments orally 3 times a day, 2 capsules each time with 2 weeks as one course and all patients received 2 successive courses of treatment. Changes of blood beta(2)-microglobulin (beta(2)-M), hemoglobin (Hb), 24 h urinary protein (24 h UP), pH value of urine and blood uric acid (BUA) as well as kidney function were observed.

RESULTSAfter treatment, level of beta(2)-M got lowered significantly, Hb and 24 h UP, blood urea nitrogen, serum creatinine and the clearance rate of creatinine, as well as blood lipids all improved obviously in the treated group (all P<0.01), while these parameters remained unchanged in the control group (P>0.05). The pH value of urine was improved in both groups showing an insignificant difference between them (P>0.05). BUA was decreased in both groups with a decrease to a larger extent in the treated group (P<0.01). The total effective rate was 87% in the treated group, which was superior to that in the control group (62%, P<0.05).

CONCLUSIONWCC has a favorable therapeutic effect on gout and its mechanism of action for improving renal function and reducing urinary protein could be related with the lowering of blood beta(2)-M, BUA and lipids.

OBJECTIVETo summarize the clinical management of abdominal compartment syndrome (ACS) in burn patients with severe burn injury.

METHODSTwelve serious burn patients with abdominal compartment syndrome hospitalized in our center from January 2001 to April 2005 were enrolled in the study. Among them 3 patients were treated with conservative method, 4 with escharectomy of abdominal wall, 5 with laparotomy for decompression. The clinical results were analyzed statistically. Bladder pressure, central venous pressure, systolic blood pressure and arterial blood oxygen partial pressure (PaO2 ) were measured and compared before and after operation.

RESULTSAmong these 12 patients, 5 died with the overall mortality of 41.67%. But only 3 died among 9 patients undergone operation. Most of patients were oliguric,with abnormal bladder pressure, central venous pressure, and systolic blood pressure 24 hours before operation. But these parameters were significantly improved after operation ( P <0. 01).

CONCLUSIONEarly abdominal escharectomy and timely abdominal decompression are vital for the management of ACS in burn patients.

Objective:To observe the efficacy and safety of mechanical thrombectomy with retrievable stent in patients with acute basilar artery occlusion (ABAO).Methods:Twenty-five patients with ABAO admitted to our hospital from December 2016 to October 2019 were chosen in our study. In patients who were eligible for intravenous thrombolysis and had onset within 4.5 h, mechanical thrombectomy with Solitaire AB stent was performed besides intravenous thrombolysis. In patients who had contraindications for intravenous thrombolysis or had onset within 4.5-24 h, mechanical thrombectomy with Solitaire AB stent or mechanical thrombectomy with Solitaire AB stent combined with balloon dilatation and stenting were performed. The prognoses of the patients were determined by modified Rankin scale (mRS) 90 d after surgery. The clinical data and efficacy of the patients were analyzed retrospectively, and the differences in clinical data and prognoses between patients with cardiogenic embolization and those with large artery atherosclerosis were compared.Results:Twenty-four patients had successful recanalization, and one failed. Follow-up for 90 d showed that 11 patients had good prognosis, 8 had poor prognosis, and 6 died. In patients with cardiogenic embolization, the occlusion sites were located in the upper segment of the basilar artery ( n=4) and the middle segment of the basilar artery ( n=10); in patients with large-artery atherosclerosis, occlusion sites were located in the middle segment of the basilar artery ( n=6) and the under segment of the basilar artery ( n=5); the distribution of basilar artery occlusion sites between patients with cardiogenic embolization and those with large artery atherosclerosis was statistically different ( P<0.05). The mRS scores 90 d after surgery showed no significant differences ( P>0.05). Conclusion:Mechanical thrombectomy with retrievable stent is safe and feasible for patients with ABAO, and the occlusion sites of the basilar artery in ABAO may indicate the etiology of occlusion.

Objective To investigate the role of insular cortex in amygdala-kindled seizures in rats.Methods Forty-eight healthy male SD rats were randomly divided into blank control group (n=8),sham-operated group (n=8) and amygdala-kindled group (n=32); no treatment was performed in the blank control group,and only implantation of electrodes was performed in the sham-operated group; implantation of electrodes and electrophotoluminescence were performed in the amygdala-kindled group to induce amygdala-kindled seizure models.Rats in the amygdala-kindled group was divided into 4sub-groups (n=8) at different times after the kindling (1,3,6 and 12 h).Fluorescence in situ hybridization and immunohistochemistry staining were employed to investigate the altered mRNA and protein expressions of activity-regulated cytoskeleton-associated protein (Arc) in the hippocampus and insula of the rat brain.Results As compared with that in the blank control group and sham-operated group,Arc mRNA expression in the amygdala-kindled sub-groups increased at 1 h after the kindling (P＜0.05),peaked at 3 h after the kindling (P＜0.05),and returned to basic level at 6 h after the kindling (P＞0.05).As compared with that in the blank control group and sham-operated group,Arc protein expression in the amygdala-kindled sub-groups increased at 3 h after the kindling,(P＜0.05),peaked at 6 h after the kindling (P＜0.05),and returned to basic level at 12 h after the kindling (P＞0.05).No significant difference on mRNA and protein expressions of Arc was noted between the sham-operated group and blank control group (P＞0.05).Conclusion Insular cortex,the amygdala and the hippocampus form a focus complex,which participates in the occurrence of temporal lobe epilepsy.
