Objective To investigate the curative effect of granulated cancellous bone autograft in treatment of refractory bone nonunion after limited contouring of bone ends. Methods Between 2003 and 2006, 13 patients with refractory bone nonunion were treated with external fixation and granulated cancellous bone autograft after limited contouring of bone ends. Results The mean follow-up period was 22.6 months (19-30 months), which showed that all patients gained bone union and resumed com-plete weight loading or previous job at final follow-up. The mean fixation time of external fixators was 10.6 months (7-18 months). The intermittent or persistent pin-track infection occurred in eight patients and relieved by pin-track care and oral or parenteral antibiotics, with no infection after removing external fixator. Conclusion The granulated cancellous bone autograft after limited contouring of bone ends is an effective method for treatment of refractory bone nonunion.

[ ABSTRACT] AIM: To investigate the underlying genetic changes of a Chinese patient with infantile malignant osteopetrosis ( IMO) .IMO is a monogenic disease, mostly caused by mutations of TCIRG1 and CLCN7 genes.The former is believed a homozygous gene and only cause the disease in homozygous or compound heterozygous status.However, it has been reported that heterozygous mutations also cause the disease in 6 non-Chinese cases.METHODS:Genomic DNA was extracted from peripheral blood of the patient and his parents.All exons and splice sites of TCIRG1 and CLCN7 genes were amplified by PCR followed by Sanger sequencing.Mutation detection in the 2 genes was also investigated in the parents. Haplotypes were constructed by variations obtained in mutation detection and microsatillites flanking TCIRG1 gene in the family by Cyrillic.Chromosomal microarray analysis ( CMA) was performed to detect copy number variations ( CNV) of the patient and his mother.RESULTS:A novel mutation c.449_452delAGAG ( p.Gln149Glnfs16) was detected in the pa-tient.This mutation truncated 666 amino acids at the C terminal of the V-ATPase 116 kD isoform a3 protein.It wiped out the entire ATPase V0 complex and was predicted to result in total loss of protein function.This mutation was also detected in the patient’ s father.No pathogenic mutation was detected in CLCN7 gene.CMA did not reveal any CNV involving TCIRG1 or CLCN7 gene.CONCLUSION:We reported a novel heterozygous mutation of TCIRG1 gene causing IMO.This represents the first IMO case in China caused by heterozygous TCIRG1 gene mutation.

Objective To study retrospectively the curative effect of emergent transcatheter arterial embolization(TAE)on ruptured liver cancer with hemorrhage. Methods Twenty-three patients with rupture of liver cancer were emergent treated with TAE for massive hemorrhage. Results Twenty-two patients were treated by TAE effectively with good hemostasis and without recurrence of bleeding as well as liver failure, except one referred for surgery due to anomalous vascular route leading to failure of catheterization. Nine of 22 patients accepted more than one time of TAE according to the curative effect and progress of the disease, but reduction of tumor size or necrosis could be achieved in all these patients. Conclusions Emergent TAE is an effective treatment for ruptured liver cancer with hemorrhage, having good effect of hemostasis and providing the possibility for subsequent treatment.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

AIM: To explore the inhibitory effect of oxymatrine (OMT) on the allergic contact dermatitis (ACD) stimulated by dinitrofluorobenzene (DNFB) and its effects on the proliferation of the lymphocytes. METHODS: ① An ACD mouse model was established by stimulation with DNFB, and then the mice were injected intraperitoneally with different dosages of OMT, PBS and hydrocortisone (HCT) respectively, the swelling degree of their auricles was examined. ② Carboxyfluorescein diacetate, succinimidyl ester (CFDA-SE) dye and flow cytometer were used to examine the fluorescence intensity changes of lymphocytes stimulated by polyclonal stimulator ConA and OMT. RESULTS: ① compared with PBS group, OMT possessed the strong inhibitory effect on the ACD caused by DNFB in a dose-dependent manner, and its inhibitory effect was equivalent to the HCT of the same dosage with fewer side effects. ② In vitro experiments proved that OMT (500, 125 and 31 mg/L) had the ability to restrain the proliferation of lymphocytes of mouse. CONCLUSION: OMT possesses an inhibitory effect on the ACD induced by DNFB, and OMT is a kind of immunosuppressor.

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.

Abstract: Objective To research the relationship between promoter polymorphism-438 A/G of thrombin-activatable fibrinolysis inhibitorgene (TAFI-438 A/G) and atherosclerotic cerebral infarction (ACI) in Chinese Han population. Methods TAFI-438A/G genotypes andtheir allele frequencies were identified with the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) in225 ACI patients and 184 healthy controls. Results There was no significant difference of TAFI-438A/G polymorphism between ACI groupand control group. Stratified by gender, in males, the incidence of A allele was 28.6% in ACI group, and 20.6% in control (P=0.039); of theAA genotype was 9.0% in ACI group, and 1.9% in control (P=0.019). But no significant difference was found in females. ConclusionTAFI-438A/G polymorphism is associated with the risk of ACI in males, that AA genotype may increase the risk of ACI.

Objective To investigate the prostecdtive efficacy of one-stage bone grafting in man-aging chronic osteomyelitis after debridement.Methods From March 1999 to May 2003, 79 patients with chronic osteomyelitis including 28 patients with nonunion underwent one-stage autogenous bone graft-ing, allografts or mixed bone grafting after debridement in Nanjing General Hospital of Nanjing Military Command.All patients were followed up for a mean period of 77 months (60-111 months).Results Six patients (8%) , including two with autogenous bone grafting, three with allografts and one with mixed bone grafting, were confirmed with recurrence of infection, with no statistical difference among three methods of bone grafting.Of 28 patients with nonunion, 23 patients with autogenous bone grafting and two with allografting obtained union, the other three patients with mixed bone grafting obtained union in two patients but resulted in recurrence of infection with nonunion in one, with cure rate of 96% (27/28).Conclusions One-stage bone grafting after debridement for infection and bone union can reach cure rate of over 90%.The recurrence of infection mostly occurs within the first year after operation, with stable long-term curative effect.
