OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

OBJECTIVETo compare clinical outcomes of swing shoulder and internal fixation in treating proximal humeral fractures.

METHODSFrom June 2007 to June 2012, totally 89 elderly patients with humeral proximal fractures were treated by swing of shoulder or internal fixation, and 81 patients were followed up. In swing shoulder group, there were 38 patients including 13 males and 25 females aged from 62 to 84 with an average of (67.11±6.18) years old; 27 cases were 2-part fractures and 11 cases were 3-part fractures according to Neer classfication. In internal fixation group, there were 43 patients including 16 males and 27 females aged from 60 to 80 with an average of (66.47±5.48) years old; and 29 cases were 2-part fractures and 14 cases were 3-part fractures according to Neer classfication. VAS score and complications were compared between two groups after treatment, and Constant-Murley functional scoring was used to evaluate shoulder function of patients.

RESULTSEighty-one patients were followed up from 13 to 26 months with an average of 18.3 months. There was no significant difference in preoperative VAS score between two groups. After treatment, VAS score in swing shoulder group was (3.11±0.95), and (3.88±1.14) in internal fixation group, and had significant difference between two groups (t=-3.313,P<0.05). There was no significant difference in Constant-Murley scores between swing shoulder group (79.53±3.73) and internal fixation group (77.98±4.11) (t=1.768,P>0.05). Postoperative complications in swing shoulder group was 18.4%(7/38), 39.5%(17/43) in internal fixation group, and had significant differences between two groups (χ2=4.313,P<0.05).

CONCLUSIONSwing shoulder for the treatment of proximal humeral fractures in elderly has advantages of low cost, less complications and good recovery of joint function; while internal fixation has a good therapeutic effect but increased complications.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

Objective To investigate the relationship between platelet-activating factor acetylhydrolase gene Arg92His(4, 275; G→A), Ile198Thr(7, 593; T→C) and Val279Phe(9, 994; G→T) mutation and cerebral artery athero-sclerosis stenosis. Methods Six hundred forty-twopatients with cerebral infarction underwent cerebral digital subtrac-tion angiography (DSA).The patients were then divided into cerebral artery atherosclerosis stenosis (CAAS) group(n=477) and control group(n=81) accroding to the site and severity of their cerebral artery stenosis. Furthermore, the CAAS group were divided into intracranial artery stenosis(ICAS) subgroup(n=251), extracranial artery stenosis(ECAS) subgroup (n=115) and extracranial-intracerebral artery stenosis(ECAS) subgroup(n=111). The distributions of genotype and allele frequencies of Arg92His,Ile198Thr and Val279Phe mutation of platelet-activating factor acetylhydrolase gene were ex-amined and comparied in different groups. Results There were significant differences in the distributions of genotype and allele of Arg92His mutation between ICAS subgroup and control group(42.6% vs. 30.3%;23.3% vs. 16.4%, P <0.05). These associations were not detected in ECAS and IECAS subgroups. There was no significant association be-tween Ile198Thr and Val279Phe and stenosis at any site(P>0.05). The distributions of genotype and allele of Arg92His, Ile198Thr and Val279Phe mutation were no significantly difference between CAAS group and control group (P >0.05). Conclusions Arg92His mutation may be associated with intracranial artery atherosclerotic stenosis.

BACKGROUNDLocalization of sensory cortical areas during the operation is essential to preserve the sensory function. Intraoperative direct electrostimulation under awake anesthesia is the golden standard but time-consuming. We applied 3T high field blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) to identify the relationship between glioma and cortical sensory areas preoperatively and to guide intraoperative direct electrostimulation for quick and precise localization.

METHODSFive glioma patients with sensory cortex involvement by or next to the lesion had preoperative BOLD fMRI to determine the spatial relationship of cortical sensory areas to the tumours. Bilateral hand opposite movement was performed by these patients for fMRI. Precentral and postcentral gyri were identified by electrical stimulation during the operation. Karnofsky Performance Status scores of the patients' pre- and postoperative and the role of BOLD fMRI were evaluated.

RESULTSThe cortical sensory areas were all activated in five glioma patients involving postcentral gyrus areas by BOLD fMRI with bilateral hand opposite movement. The detected activation areas corresponded with the results from cortical electrical stimulation.

CONCLUSIONSThe relationship between cortical sensory areas and tumour can be accurately shown by BOLD fMRI before operation. And the information used to make the tumour resection could obtain good clinical results.

OBJECTIVETo observe the biomechanical effects of the lateral wall of the femur in treating femoral intertrochanteric fractures with intramedullary or extramedullary fixation to guide the choice of clinical fixed methods.

METHODSTwelve adults femur specimens of intertrochanteric fractures were belong to the type A1 of the AO fracture classification and randomly divided into the lateral wall complete PFNA group, the lateral wall complete PF-LCP group, the lateral wall breakage PFNA group, lateral wall breakage PF-LCP group, every group had 3 specimens. The four groups of specimens were subjected to compressive loading experiment with Universal Material Testing Machine. The maximum loading force was observed. The distance between fracture ends, the distance of fracture dislocation and the sliding distance of the fracture fragments along the intertrochanteric were measured with Calipers.

RESULTSThe maximum loading force of lateral wall complete PFNA group were larger than that of lateral wall complete PF-LCP group, and the maximum loading force of lateral wall breakage PFNA group were larger than that of lateral wall breakage PF-LCP group, there were significant differences (<0.05). The distance between fracture ends of the four groups before compression were not significant differences(>0.05). The distance between fracture ends, the distance of fracture dislocation and the sliding distance of the fracture fragments were not significant differences between lateral wall complete PFNA group and lateral wall complete PF-LCP group after compression (>0.05). But the distance between fracture ends, the distance of fracture dislocation and the sliding distance of the fracture fragments of lateral wall breakage PFNA group were less than that of lateral wall breakage PF-LCP group(<0.05).

CONCLUSIONSIntramedullary fixation of intertrochanteric fractures have stronger loading force. Both intramedullary and extramedullary fixation of intertrochanteric fractures have strong stability when the lateral wall of the femur is complete, but intramedullary fixation of intertrochanteric fractures is stronger stability than extramedullary fixation when the lateral wall of the femur is broken. So the intramedullary fixation is the first choice for the treatment of intertrochanteric fracture.

OBJECTIVETo evaluate the stability of hearing results and complications in long-term following-up who underwent reconstruction surgery.

METHODSSix hundreds and seventy five cases (700 ears) of congenital aural atresia were reviewed from January 1984 to January 2001 at the Department of Otorhinolaryngology Head and Neck Surgery, Tongren hospital. Except 40 ears undone hearing reconstruction, 635 cases (660 ears) underwent long-term following-up for 3 to 19 years, with an average of 7.9 years.

RESULTSStenosis and recurrent infection of the external auditory canal (EAC) were the most frequent complications. Stenosis was seen in 120 ears, and 2 ears re-atresia, with an incidence of 18.48% (122/660). Recurrent infection of the cavity and canal skin happened in 6 ears. Closure of the air-bone gap (ABG) post-operation were gained in all cases, and ABG gains 20 dB or more occurred in 512 ears (77.57%), but 30 dB or more in 231 ears (35%). Following-up results: Stable hearing results gained in 450 ears over the length of following-up; the hearing worsened than that of 3 weeks postoperatively occurred in 160 ears, including 2 ears with sensorineural hearing loss. Hearing deteriorated more than 20 dB happened in 35 ears, and 10-15 dB in others cases but still be improved compared with that of preoperation.

CONCLUSIONSAtresiaplasty surgery in individuals with congenital aural atresia can yield reliable, lasting hearing results in 68.2% (450/660), with a low incidence of complications; the initial improved hearing deteriorated gradually over the first 6 months post-operation, which are related with the stenosis and infection of canal. Cavity adhesion, bony EAC re-growth, ossicular chain re-fixation or displace may affect the hearing results in some cases. Even unilateral aural atresia may benefit from the reconstruction surgery and achieve serviceable hearing results.

BACKGROUNDBlood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) plays an important role in identifying functional cortical areas of the brain, especially in patients with gliomas. This study aimed to assess the value of fMRI in presurgical planning and functional outcome of patients with gliomas in the motor cortical areas.

METHODSTwenty-six patients with gliomas in the motor cortex were recruited in the study. Before operation, fMRI was performed in each patient to obtain the mapping of bilateral hands area on the primary sensorimotor cortex. This examination was performed on a 3.0T scanner with a bilateral hands movement paradigm. During microsurgery under awake anesthesia, the motor area was identified using direct electrical stimulation and compared with preoperative mapping. Finally the tumor was resected as much as possible with the motor cortex preserved in each patient. Karnofsky performance status (KPS) was evaluated in all patients before and after operation.

RESULTSTwenty-three patients showed a successful fMRI mapping. Among them, 19 were classified to be grade III; 4, grade II; 3, grade I. The operation time was about 7 hours in the 23 patients, 8.5 hours in the other 3. The pre- and postoperative KPS score was 82.3 +/- 8.6 and 94.2 +/- 8.1, respectively.

CONCLUSIONSPreoperative fMRI of the hand motor area shows a high consistency with intraoperative cortical electronic stimulation. Combined use of the two methods shows a maximum benefit in surgical treatment.
