Objective To explore the treatment to craniocerebral injury.Methods 6 patients suffered from serious, developing head injury with epidural and subdural hematoma were processed by cone socket hematoma drainage in ward before hematoma was eliminated.Results Hematoma drainage can be performed within 20 min after hospitalization. No case died and no infection occured. The score of Glasgow Outcome Scale were Ⅴ(2 cases), Ⅳ(2 cases),Ⅲ(1 case) and Ⅱ(1 case) 3 months after operation.Conclusion Cone socket hematoma drainage in ward is a good method to treat craniocerebral injury.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.

?AlM:To compare the anti-inflammatory effects with lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops after phacoemulsification combined intraocular lens implantation.
? METHODS: ln this prospective, comparative, randomized controlled trial, patients with senile cataract who underwent phacoemulsification combined intraocular lens implantation in our hospital from January 2014 to October 2014 were enrolled, which were randomly divided into two groups. Patients were given lotrprednol -tobramycin ( LE/T group ) and dexamethasone-tobramysin ( D/T group ) eyedrops respectively. Preoperative and postoperative intraocular pressure, malnutrition inflammation score, bruggrmann comfort scale were observed.
?RESULTS:A total of 143 eyes of 143 cases were enrolled, of them 81 cases were in the LE/T group and 62 in the D/T group. There were no statistically significant differences between the two groups in malnutrition inflammation score and bruggrmann comfort scale. The average intraocular pressure was 16. 5±3. 1mmHg in D/T group after 14d postoperation, which was obviously higher than LE/T group ( 14. 7± 3. 7mmHg, P = 0. 004 ). After 14d postoperation, the intraocular pressure of 2 cases were > 21mmHg, which were back to normal after drug withdrawal.
? CONCLUSlON: The anti - inflammatory effects lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops are similar after phacoemulsification. However, lotrprednol-tobramycin has little influence in intraocular pressure, and more safety.

Aim To study the effect of Baoxinbao film on endothelin(ET) and nitric oxide(NO) secretion in patients with stable angina pectoris(SAP).Methods 76 patients with SAP were randomly divided into two groups, with 40 cases in the baoxinbao group plastered with baoxinbao film and 36 cases in the isosorbide dinitrate group receiving isosorbide dinitrate. The levels of plasma ET and NO before and after treatment were observed. Results The concentrations of plasma ET were increased and plasma NO reduced significantly in the SAP patients respectively, as compared with those in the control group(all P

Objective To introduce a new technique for urethral coverage in Snodgrass hypospadias repair,and to evaluate its effectiveness and complications.Methods From April 2003 to February 2006, this new procedure was performed in 289 children with hypospadias aged 3 months to 12 years (mean age,2. 4 years).The native meatus of urethra was identified subcoronal in 78 cases,penile/shaft in 136,penoscrotal in 36 and scrotal in 16;and 23 cases had undergoneⅡstage operation and re-operation.The overlapping coverage with bilateral shaft based vascularized dartos pedicle was done in the new urethra by Snodgrass hy- pospadias repair in these children.Results All the cases were followed for 3 months to 2 years.Postoper- atively,urinary fistulas developed in 32 cases (11%).Of them,11 were cured spontaneously within 4 weeks. The incidence of actual urinary fistula was 7% (21/289).Of the 21 fistulas which were not cured,11 (5%) occurred in 214 cases of distal hypospadias;and 10 (13%) in 75 cases of proximal hypospadias,Ⅱstage and re-operation.No dehiscence and diverticulum was found.Combined with mucosal collar technique,the ventral skin of the penis was sewn on the midline.During the follow-up,excellent cosmetic results with normal-ap- pearing circumcised penis were achieved in most patients.Conclusions Bilateral shaft based vascularized dartos pedicle urethral coverage procedure is a reliable and effective method for preventing urethral cutaneous fistulas and dehiscence.This method can reconstruct a satisfactory cosmetic appearance of the penis.

AIM: To re-identify the special motif regulating osteoclast(OC)differentiation in receptor activator of nuclear factor kappa B(RANK)to provide evidences for studying the mechanism of OC differentiation.METHODS: Eight amino acids were mutated(from DIIVVYVS into ELLAAFAA)in the fragment between the 533th and the 540th amino acids in RANK cytoplasmic domain.Eight mutant TNFR1/RANK chimeras,each consists of TNFR1(tumor necrosis factor receptor 1)extracellular domain linked to transmembrane domain and cytoplasmic domain of RANK with one amino acid mutated in cytoplasmic domain was constructed by point mutation method.After the eight mutant chimeras were finished,they were packed with plat E cell line to produce the retrovirus expressing mutant TNFR1/RANK.The bone marrow macrophages(BMMs),isolated from TNFR1/R2 double knockout mice,were infected with retrovirus derived from different mutants and infected BMMs which did not differentiated into OCs were inspected after stimulated by TNF-? and M-CSF.The fragment consisted of different amino acids in TNFR1/RANK chimeras,which couldn't induce OC formation after mutated,may be the special motif regulating OC differentiation.RESULTS: We found that all BMMs transfected by TNFR1/RANK-533,TNFR1/RANK-539 or TNFR1/RANK-540 differentiated into OCs,indicating that none of amino acids D533,V539 or S540 had an effect on OC differentiation.A fewer of BMMs transfected by TNFR1/RANK-534 differentiated into OCs,indicating that I534 had a partial effect on OC formation.Most importantly,BMMs transfected TNFR1/RANK-535,TNFR1/RANK-536,TNFR1/RANK-537 or TNFR1/RANK-538 did not differentiated into OCs,indicating each of amino acids I535,V536,V537 and Y538 played a pivotal role in OC differentiation.CONCLUSION: The amino acid fragment consists of I534,I535,V536,V537 and Y538 may be the special motif regulating OC differentiation in RANK.

OBJECTIVETo compare the clinical therapeutic effects differences between acupuncture at Suliao (GV 25) and Shuigou (GV 26) on promoting regain of consciousness from coma in severe craniocerebral injury.

METHODSBased on regular emergency treatments of neurosurgery, eighty-two cases of craniocerebral injury who were under stable condition were randomly divided into an observation group (42 cases) and a control group (40 cases). Suliao (GV 25) was selected as main aupoint, while Laogong (PC 8) and Yongquan (KI 1), etc. were selected as adjuvant acupoints and Neiguan (PC 6), Sanyinjiao (SP 6), Yifeng (TE 17) and Wangu (GB 12), etc. were selected as matching acupoints in the observation group where a strong needle manipulation was applied to improve the regain of consciousness. The main acupoint of Shuigou (GV 26) along with identical adjuvant acupoints and matching acupoints in the observation group were selected in the control group with identical strong needle manipulation. The treatment was given once a day in both groups, five times per week and ten times were considered as one session. The immediate clinical symptoms after acupuncture at Suliao (GV 25) and Shuigou (GV 26) were observed as well as Glasgow coma scale (GCS) before the treatment, after 45 days and 90 days of treatment to assess the resuscitation time and rate. Also the clinical efficacy was compared between both groups.

RESULTSThe occurrence rate of sneezing reflex was 85.7% (36/42) in the observation group, which was higher than 25.0% (10/40) in the control group (P < 0.01). The average resuscitation time was (64.6 +/- 19.4) days in the observation group, which was obviously shorter than (73.8 +/- 14. 6) days in the control group (P < 0.05). The resuscitation rate was 88.1% (37/42) in the observation group, which was similar to 75.0% (30/40) in the control group (P > 0.05). Compared before the treatment, GCS were both improved after the treatment in two groups (both P < 0.01). The 90-day GCS was 9.52 +/- 2.32 in the observation group, which was superior to 8.47 +/-2.14 in the control group (P < 0.05). The curative and markedly effective rate was 45.2% (19/42) in the observation group, which was superior to 22.5% (9/40) in the control group (P < 0.05).

CONCLUSIONThe effect of acupuncture at Suliao (GV 25) on improving regain of consciousness from coma in severe craniocerebral injury is positive. It could specifically improve sneezing reflex and stimulate respiratory center, which has more obvious effect than acupuncture at Shuigou (GV 26).

OBJECTIVETo compare the leukemia-associated immunophenotypes (LAIP) in patients with B lineage acute lymphoblastic leukemia (B-ALL) at diagnosis and relapse, and investigate its implications for minimal residual disease (MRD) detection.

METHODSThe immunophenotype of leukemia cells from 410 newly diagnosed and 6 relapsed patients with B-ALL were detected by four to six antibody combination, mainly CD34/CD10/CD45/CD19 of 4-color CD45/SSC gating flow cytometry (FCM).

RESULTSThe proportion of CD45 under-expressed or negative in relapsed patients was much higher than that in newly diagnosed patients, being 69.2% and 37.8% respectively. Immunophenotypic changes occurred in 9 relapsed patients (including 8 hematological relapse and 1 central nerves system relapse) when analyzed by paired samples analysis at diagnosis vs at relapse: 4 cases showed CD45 down-modulation and 2 up-modulation; 4 CD34 down-modulation and 2 CD10 up-modulation, while the expression of CD19 remained no change. MRD was observed in all 7 cases of hematological relapse 2 - 4 months before relapse, and the immunophenotype of MRD cells was the same as that in relapse.

CONCLUSIONA high frequency of immunophenotypic changes occurred at relapse and even in MRD before relapse, however the accuracy of MRD monitoring seemed not affected by the FCM strategy used in this investigation.

OBJECTIVETo evaluate the clinical significance for minimal residual disease (MRD) detection by 4 color flow cytometry in B lineage acute lymphoblastic leukemia (B-ALL).

METHODSMRD was analyzed and followed up by using two panels of 4 color antibodies, mainly CD34/CD10/CD45/CD19, in 671 consecutive bone marrow specimens and 1 cerebrospinal fluid from 98 B-ALL patients. In 26 cases of them the immunophenotyping informations at diagnosis were not available.

RESULTSOf 671 bone marrow samples, 579 were MRD negative with leukemic cells below 0.0001 and 93 were MRD positive with leukemic cells over 0.0001. Of 93 MRD positive samples, leukemic cells below 0.05 were found in 64 bone marrow samples, meanwhile in the other 29 samples leukemic cells were over 0.05. Twenty patients relapsed, 19 were bone marrow relapse and one center nerves system. Fifteen of them were found MRD positive 7 - 17 weeks before relapse including 6 patients having no immunophenotyping data at diagnosis. The percentages of leukemia cells in these 15 patients were all over 0.0001. Two relapsed patients were MRD negative in 3 and 9 months before relapse, respectively. Two relapsed after MRD monitoring stopped. If MRD level was > 0.0001 at the end of induction chemotherapy and 12 weeks of treatment, the rate of relapse was 50% (6/12), while, it was 7.5% (3/40) in MRD negative patients (P = 0.000).

CONCLUSIONRelapses can be predicted by MRD monitoring, if MRD was positive in the early phase of treatment, the risk of relapse was higher. Based on the characteristics of B cells ontogeny, MRD detection can be done independently of immunophenotypic information at diagnosis.
