ObjectiveTo study the Resultsof splenectomy for recurrent hypersplenism after splenic arterial embolization. MethodsA retrospective analysis was carried on 12 p1atients who underwent splenectomy for recurrent hypersplenism after splenic arterial embolization which had been carried out in 51 patients at this hospital from Jan. 2001 to Dec. 2008. ResultsSplenectomy was successfully carried out in all the 12 patients. The operative time ranged from 90 to 240 minutes. The mean blood transfusion was 810 ml. There was 1 case of pancreatic leakage after the operation, which healed with drainage for 4 weeks. One patient developed upper gastrointestinal hemorrhage 14 months after the operation, and he received a meso-caval shunt. Conclusion We should select patients carefully for splenic arterial embolization as splenectomy after splenic arterial embolization is difficult.

In the paper, the training situation of clinical pharmacist of Chinese medicine was analyzed through the current work situation of clinical pharmacy of Chinese medicine in China. The lack of staff and low level are the undoubted facts. In order to promote clinical pharmacy of traditional Chinese medicine, clinical pharmacists with high quality should be trained. How to train clinical phar-macists of Chinese medicine with high quality, some suggestions were put forward from two aspects of the college education reform and clinical training:①The existing education system should be reformed to establish reasonable higher education for clinical pharmacy of Chinese medicines, including the reform of education system, the curriculum adjustment, practice direction change and so on;②With the attention of all the parties, practical talents of clinical pharmacy of Chinese medicine should be trained in clinics, including the na-tion should start the training for clinical pharmacist of Chinese medicine, hospitals should train practical clinical pharmacist of Chinese medicine and carry out the corresponding work of clinical pharmacy of Chinese medicine, staff should improve self quality and so on.

Objective To explore the safety, feasibility, and techniques of hand-assisted laparoscopic splenectomy (HSLS) for massive splenomegaly. Methods Between January 2005 and December 2006, 40 patients with massive splenomegaly owning to portal hypertension were treated with HSLS or open splenectomy (OS). The two groups were comparable in age, sex, hepatic function by Child classification, and size of the spleen. Results No serious complications occurred in both the groups. Compared with the OS group, patients in the HALS group had more blood loss [ (312?61) ml vs (235?105) ml, t=2.583, P=0.014], longer operation time [(95?20) min vs (73?16) min, t=3.832, P=0.000], earlier recovery of intestinal function [(48?1) h vs (98?1) h, t=-153.093, P=0.000], and shorter postoperative hospital stay [(6?2) d vs (10?2) d, t=-6.124, P=0.000]. Conclusions HSLS is feasible and safe for patients with massive splenomegaly. Despite a longer operation time, the procedure is superior in postoperative recovery.

Objective To discuss the application value of DWI and ADC on predicting therapeutic effect of radiotherapy treatment in NPC. Methods Twenty four local recurrent cases and 38 non-recurrent cases after radiotherapy treatment in NPC were reviewed. MRI and DWI-MRI were performed at pre-radiotherapy and 3, 6, 12 months after treatment, the ADC values of the lesions were analyzed by SPSS 18.0 statistical software. ROC curves based on the ADC values were measured in 3, 6, 12 months after treatment plotted to analyze the threshold ADC value for confirming recurrence. Results The recurrent group and newly diagnosed group showed significantly high signal on DWI, while the non-recurrent group acquired low or mixed signal. The ADC values of the primary tumor in the recurrent group and the non-recurrent group were (0.709 ± 0.078) × 10-3 and (0.693 ± 0.089) × 10-3mm2/s, respectively, t=-0.717,P>0.05, respectively.The ADC values of the primary and recurrent tumor in the recurrent group were (0.730± 0.068) × 10-3mm2/s and (0.709 ± 0.078) × 10-3mm2/s, t=-1.000,P>0.05 , respectively.There were statistical differences between the recurrent group and the non-recurrent group for ADC in 3, 6, 12 months after treatment:(1.128 ± 0.179) × 10-3 and (1.358 ± 0.145) × 10-3mm2/s, t=5.567,P<0.01;(1.164 ± 0.174) and (1.450 ± 0.102) × 10-3mm2/s, t=7.310,P<0.01;(1.107 ± 0.180) × 10-3 and (1.584 ± 0.125) × 10-3mm2/s, t=11.189,P<0.01;respectively. Take 1.29 × 10-3 mm2/s,1.32 × 10-3mm2/s,1.37 × 10-3mm2/s respectively in 3, 6, 12months after treatment as the diagnostic threshold to predict tumor recurrence. The sensitive , specificity, and accuracy were (83.3%, 73.7%, 77.4%), (83.3%, 89.5%, 87.1%), (100.0%, 94.7%, 96.3%).Conclusions Both DWI and ADC value are important for diagnosing and predicting recurrent NPC after radiotherapy treatment, DWI and ADC can be used to regular follow-up after radiotherapy, to further improve the rate of early diagnosis of recurrent NPC.

Objective To investigate an appropriate megavoltage computed tomography ( MVCT ) protocol to guide helical tomotherapy ( HT) for multiple metastases. Methods According to the location of target volume, 48 patients with multiple metastases undergoing HT were divided into head/chest group ( n=15), head/pelvis group (n=15), and chest/pelvis group (n=18). Each target volume received MVCT scans during the treatment. The obtained MVCT images were registered to CT images and the setup errors were recorded. The CTV?PTV margins were calculated. Comparison was made by paired t test. Results In the head/chest group, there was no significant difference in the setup error in x?axis between the head and chest (-0.15±1?25 vs. -0.21±2?34, P=0?71), while the head had significantly smaller setup errors in y?and z?axis than the chest (0.73±1?22 vs. 1.56±2?54, P=0?00;0.93±1?44 vs. 2.65±1?88, P=0?00). In the head/pelvis group, the head had significantly smaller setup errors in x?, y?, and z?axis than the pelvis (-0.16±1?31 vs. -1.29±3?72, P=0?00;0.81±1?34 vs. 3.20±3?90, P=0?00;1.24±1?75 vs. 5.49±2?80, P=0?00) . In the chest/pelvis group, there were no significant differences in setup errors in x?or y?axis between the chest and pelvis (-0.25± 2?90 vs. -0.22± 3?65, P=0?06;0.35± 3?60 vs. 0.38± 3?78, P=0?87), while the chest had a significantly smaller setup error in z?axis than the pelvis (1.95±2?81 vs. 3.35± 3?05, P=0?00) . In the three groups, the CTV?PTV margins of lower target volume were reduced in three dimensions after the correction of upper target volume, in which y?axis showed the largest reduction of CTV?PTV margins (5?13 vs. 4?01;9?17 vs. 8?30;8?52 vs. 7?13). Conclusions The setup error of individual target volume should not be used for correction of the overall setup error in HT for multiple metastases with isolated target volume. An MVCT protocol that provides image?based guidance for multiple target volumes is recommended.

It is of great clinical significance to improve the diagnosis of HCC.

Objective To discuss the prevention and treatment of the complications of modified radical mastectomy with nipple-areola complex (NAC) sparing. Methods The clinical data of 124 breast cancer patients who had a NAC sparing modified radical mastectomy from January 1998 to December 2008 were analyzed retrospectively. The causes of complications were evaluated and the proposal of prevention and treatment was put forward. Results Of the 124 patients, 18 had nipple necrosis (14.52%), 9 had skin infections and necrosis (7.26%), 7 subcutaneous hydrops(5.65%), 5 upper extremity lymphedema (4.03%), 3 chest muscle contracture with ipsilateral upper limb dyskinesia (2.42%), and 2 operative residual cavity hemorrhage(1.61%). Conclusion All the post-operative complications listed above could be possibly avoided by more careful operation procedure.

Radiotherapy is a treatment for cancer with undesired by-effects. In order to develop a new radiation protective agent that could reduce the by-effects, we tried to express and purify human cryptochrome 1 (hCRY1). The coding sequence of hCRY1 was inserted into prokaryotic expression plasmid pET28a(+), and this protein was purified from Escherichia coli BL21(DE3) after IPTG induction, ultrasonication, inclusion body dissolution, gradient dialysis, nickel column purification and ultrafiltration. The yield of hCRY1 in 1 L E. coli culture (LB medium) was about 10-15 mg. The radiation protective efficiency of hCRY1 was monitored by detecting X-ray-induced H2A.X foci in HaCaT cells. The results of immunofluorescence show that hCRY1 significantly reduces X-ray stimulated DNA damage response. The apoptosis of HaCaT cell was also detected, and the repression of H2A.X foci formation was not due to hCRY1's cytotoxity. All these data suggest a potential application of recombinant hCRY1 as a protective agent for radiotherapy.

Objective To investigate the characteristics and outcome of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in patients with renal injury. Methods AAV patients with renal injury diagnosed in the Department of Nephrology, Renmin Hospital of Wuhan University, from January 2012 to January 2017 were included into this study. Patients were divided into MPO-ANCA positive and PR3-ANCA positive groups for further study. The clinical characteristics, pathological and laboratory indexes, treatment and prognosis were retrospectively analyzed. Results A total of 68 cases were enrolled, among which 52 cases (76.5%) were MPO-ANCA positive and 16 cases (23.5%) were PR3-ANCA positive, and 41 patients (60.3%) were over 65 years old. The incidences of interstitial lung disease, digestive and nervous system damage in PR3-ANCA positive group were significantly higher than those MPO - ANCA positive group (P<0.05). There were significant differences of hemoglobin, complement C3, complement C1q, IgE, 24 h urinary protein,erythrocyte sedimentation rate, procalcitonin, BVAS score and eGFR in two groups (P<0.05). 19 cases had done renal biopsy ,among them 14 cases were MPO-ANCA positive and 5 cases were PR3-ANCA positive. Incidence of crescentic necrotizing glomerulonephritis in PR3-ANCA positive group was significantly higher than that in MPO - ANCA positive group, and incidence of diffuse global glomerulosclerosis in MPO-ANCA positive group was significantly higher than that in PR3-ANCA positive group (all P<0.05). At the median follow-up time of 32 months, the relapse rate at 6 month of MPO-ANCA-positive and PR3-ANCA-positive patients were 46.2% and 75.0%, respectively (P<0.05). Multivariate logistic regression analysis showed that PR3-ANCA positive, age≥65 years old, baseline eGFR<30 ml·min-1·(1.73 m2)-1, and combined with pulmonary interstitial lesions were all independent risk factors for relapse. And the incidence of ESRD were 42.3%and 75.0%during the follow-up period and 10 patients (14.7%) died. COX regression analysis showed that patients older than 65 years old, BVAS score≥18 points, eGFR<30 ml·min-1·(1.73 m2)-1 and complicated with pulmonary interstitial disorders at the onset were independent risk factors causing ESRD or death. Conclusion The PR3-ANCA-positive patients had more severe renal injury than those with MPO-ANCA-positive patients, and the injury of extrarenal organs was more serious, recurrence rate was higher, and the prognosis was worse.

Objective Our study aimed to delineate the clinical and radiological features of patients with anti-myelin oligodendrocyte glycoprotein antibody (MOG-Ab)positive neuromyelitis optica spectrum disorder (NMOSD). Methods Fifty-seven patients with NMOSD and 29 patients with multiple sclerosis (MS) were collected. Data on clinical and radiological features of MOG-Ab positive patients with were analyzed retrospectively. Results MOG-Abs were present in 9/57 (15.8%) NMOSD patients and 2/29 (6.9%) MS patients. Both MOG and aquaporin-4 (AQP4) antibodies were positive in one case of NMOSD. There was no significant difference between the two groups (P＞0.05). There were more females than males having MOG-Ab positive NMOSD (females: males=7:1) and the average onset age was 41.4 ± 11.5 years. There was no significant difference in gender and age between MOG-Ab negative and AQP4-Ab positive groups(P＞0.05). The durations of disease were significantly shorter in either MOG-Ab positive NMOSD patients or MOG-Ab negative NMOSD patients than in AQP4-Ab positive group (P<0.05). Recurrence was the main disease pattern of all three groups and the frequency of recurrence was not significant different among three groups (P＞0.05). The incidence of optic neuritis was 62.5% in NMOSD patients with MOG-Ab positive and 43.5% in AQP4-Ab positive NMOSD patients (P＞0.05). There was no significant difference in the morphology and location of brain lesions among the three groups (P＞0.05). MOG-Ab positive NMOSD patients had long segment spinal cord lesions. The median length of the spinal cord lesions in the MOG-Ab positive group was similar to the other two groups (P＞0.05). Conclusions MOG-Ab positive NMOSD patients have higher proportion of females with shorter recurrence course, more likely complicated with optic neuritis. And the radiological features of brain and spinal cord were not specific to patients with AQP4-Ab positive.
