The statistical data on Traditional Chinese Medicine (TCM) has not been fully exploited,resulting in the gap between the storage and usage of the TCM statistical data resources. The study on the retrospective collection, arrangement and application of Traditional Chinese Medicine Statistical Data aims to enhance the usage of TCM statistical data, basing on the collection and arrangement of the authoritative TCM statistical data, common analysis of the TCM statistical data from the founding of the People Republic of China.A pilot TCM Statistics Information Database and a TCM Health Statistics Data Query System have been established with the computer database technology, the object-oriented programming tool (C#) and the Internet Browser-based presentation programming tool (ASP. Net), providing the initial functions of the data retrieval and the graphical presentation of the search results on TCM statistics data. This paper explores "statistical data-oriented with attributes description" as the idea to establish the statistical database of complex statistical data, with the solution of the data problems such as numerous of data, diverse of data units, lack of regularity and hard to be classified. The study realizes the building of TCM Statistics Information Database and the retrieval finction of TCM statistical data, which lays a foundation on the building of Traditional Chinese Medicine Industry Statistics Database and the information services of TCM statistics data in the future.

Background:Gastric cancer(GC)is the fourth commonly seen cancer in the world. The role of Notch signaling pathway in the pathogenesis of tumors has become a focus in related studies,however,the underlying mechanism of Notch1 in GC has not yet been fully understood. Aims:To investigate the expression and significance of Notch1 in human GC tissue. Methods:A total of 115 patients with GC admitted at Jiaxing First Hospital from October 2011 to July 2014 were enrolled. Expression of Notch1 in cancerous tissue and para-cancer noncancerous tissue was determined by immunohistochemistry. The correlation between expression of Notch1 and clinicopathological characteristics of GC was analyzed. Results:Expression rate of Notch1 in cancerous tissue was significantly higher than that in para-cancer noncancerous tissue(73. 9% vs. 3. 5% ,P < 0. 001). Notch1 expression in cancerous tissue was significantly correlated with depth of vascular involvement,lymph node metastasis and TNM stage of GC(P < 0. 05). Conclusions:Notch1 as a cancer-promoting gene is involved in the pathogenesis of GC,and has a close association with tumor invasion and metastasis.

Objective To identify highly sensitive and specific antigens in Aeromonas hydrophila strain ATCC7966 by using immunoproteomics.Methods Outer membrane proteins were extracted from the Aeromonas hydrophila strain by using two-dimension electrophoresis and identified by LC-LTQ-XL-MS ( liq-uid chromatography coupled with linear ion trap mass spectrometry).Western blot assay was performed to screen out the immunogenic proteins.Results A total of 43 peptides representing 39 proteins were identi-fied by LC-LTQ-XL-MS.Among the 39 proteins, 69% were outer membrane proteins and 12% were inner membrane proteins.They were involved in the process of transportation, cell motility, biosynthesis, etc. One candidate vaccine antigen was identified by using two-dimensional Western blot analysis .Conclusion The immunoproteomics approach could be used to identify immunogenic proteins of Aeromonas hydrophila. This study provided references for further investigation on candidate vaccine antigens.

Objective To study positron yield quantitatively in different phantoms by means of PET imaging after high energy photon irradiation,and to investigate the feasibility of bio-dose verification by PET in high energy photon radiotherapy.Methods The phantoms (hydrogel,HDPE,inhomogeneous phantom) were scanned with PET 1 min later after exposure to 2,4,6,8 Gy dose with/using 25 and 50 MV photon irradiation.The positron account rates were recorded every minute in PET scanning process and then fitted to get the half-lives of yielded nuclides.Positron distribution in each phantom was compared with dose distribution to investigate the relationship between positron activity and dose delivered.Results The half-lives of nuclides yielded in hydrogel and HDPE were supposed to be 2.23 and 19.47 min,respectively by fitting results,which had negligible difference with half-lives of 11C (20.2 min) and 15O (2.08 min).The positron amounts induced by 50 MV photon in hydrogel and HDPE were 3.88 and 3.86 times that of 25 MV photon,and increased in proportion to dose delivered.Except for build-up region and cavity,activity distributions in depth and off-axis were similar to dose distribution.Conclusions The amount and distribution of positron induced by high energy photon are related to dose delivered,and it is feasible to do dose verification with PET imaging in high energy photon radiotherapy.

BACKGROUND:Different methods and biomaterials have been applied in animal experiments and clinical practice to prevent the formation of epidural scars,Biodegradable and sticky semi-fluid gels are the most often used material.Salvia miltforrhiza radix (SMR) and carbomer have been clinically confirmed to be the safe and effective drugs and gel agents. OBJECTIVE:To observe the effect of SMR-gel on preventing epidural adhesion after laminectomy.DESIGN:A complete randomized grouping design, a controlled experiment. SETTING:Department of Orthopaedics,Shenzhen People's Hospital (Second Clinical College of Jinan University). MATERIALS:Thirty-six healthy pure New Zealand rabbits were used,either male of female,clean degree,2-3 years of age. They were randomly divided into four groups with 9 rabbits in each group:blank control group,gel contro group, HA group and SMR-gel group. Carbomer934 powder (Shanghai People's Pharmaceutical Factory, batch number: 20000510) , hyaluronic acid (HA) [Shandong Bausch & Lomb Freda Pharaceutical, Co., Ltd.,No.H10960136,2 mL (20 mg)].METHODS:The experiments were carried out in the animal laboratory of Shenzhen People's Hospital from April 2002 to August 2003.①Preparing SMR-gel:SMR was prepared into extract powder.Carbomer934 powder was added by water for dissolving and swelling and stayed overnight,then SMR-gel was prepared by dipping with triethanolamine,adding with SMR extract powder (2 g),then adding with purified water till 100.0 g and stirring uniformly.②The rabbits were anesthetized. and the lamina of vertebra was totally resected at L3 and L6 (reserving superior and Inferior articular processes).then defects of 10 mm×5 mm were made to expose the dura mater.The vertebral defects were added with 1 mL carbomer gel, 1 mL HA (20 g/L) and 1 mL SMR-gel in the gel control group,HA group and SMR-gel group respectively.whereas nothing was added in the blank control group.③Gross samples:Three rabbits were killed 4,6 and 8 weeks postoperatively in each group.vertebraI ventral fascia were stripped to remove the spinal segments (L3,L6) for operation completely,and totally 24 samples for each time.One sample was selected in each group 4 weeks postoperatively. and the samples were observed under H-600 transmission electron microscope (Hitachi). ④The adhesion compactness of scar tissue with dura mater was evaluated in the 24 samples of the 4 groups at 8 weeks postoperatively:There were 4 grades:No obvious adhesion between dural sac and scar tissue for grade O:Extensive and compact adhesion between dural sac and scar tissue. impossible blunt dissection between dural sac and scar tissue.incomplete dural sac after sharp dissection for grade Ⅲ.Each spinal segment was cut into 4 parts equally,and all were prepared into sections and stained,then the thickness of epidural scar was determined with Tiger2000 image analyzer. ⑤The rank sum test was used in the scar adhesion compactness grading evaluated with naked eyes,whereas analysis of variance.and two-two comparison were used in analyzing the thickness of epidural scar.P＜0.05 was considered as significant difference.MAIN OUTCOME MEASURES:①Results of gross scar adhesion compactness grading at 8 weeks and comparison of the thickness of epidural scar at 4.6 and 8 weeks;②Results of gross observation,histological examination and ultrastructure.RESULTS: All the 36 rabbits were involved in the analysis of results. ①Results of gross observation and pathohistological examination:There was compact adhesion at each time point in the blank control group,part adhesion in the gel control group and HA group, and no obvious adhesion in the SMR-gel group.②Results of quantitative analysis:The rabbits with lower scores of scar adhesion compactness grading In the blank control group,gel control group and HA group were obviously fewer than those in the SMR-gel group (W=45-52,P＜0.05-0.01).The scar thickness at 4 and 8 weeks in the SMR-gel group was obviously less than that in the other 3 groups(F=128.657,152.246,80.891,P＜0.01).③Results of observation under transmission electron microscope:The proliferation of fibroblasts at 4 week was active in the blank control group,gel control group and HA group,but inactive in the SMR-gel group.CONCLUSION:①SMR can inhibit the fibroblasts to proliferate,differentiate and synthetize into secretory collagens,and then inhibit the formation of epidural scar adhesion.②HA can be absorbed by organs very early,which reduces its role in preventing adhesion.Whereas carbomer gel can stay longer, and it plays a role in inhibiting and blocking adhesion in the whole process of wound repairing.

OBJECTIVE: To evaluate the relation of EB virus latent membrane protein-1 (LMP-1) and the phenotype of epithelial-mesenchymal transition (EMT) and cervical lymph node metastasis in nasopharyngeal carcinoma. METHOD: Based on histopathology and MRI imaging, nasopharyngeal biopsy tissues from 88 patients with nasopharyngeal carcinoma were divided into 3 groups: pathologic metastasis (18), MRI metastasis(40) and without metastasis (30). The expressions of LMP-1, STAT3, Twist, E-Cadherin and Vimentin were examined immunohistochemically in biopsy tissues. RESULT: LMP-1 expression was found in 35 of 88 biopsy tissues with a positive rate of 38.7%. The positive rates of LMP-1 in groups of pathologic metastasis, MRI metastasis and without metastasis were 38.9% (7/18), 47.5% (19/40) and 30.0% (9/30), respectively, and significant difference were not found among three groups. The expression of LMP-1 was positively correlated to both expressions of Twist and Vimentin (r = 0.276 and 0.282, are P < 0.01), but not to both expressions of STAT3 and E-Cadherin. The positive expressions or abnormal expression of STAT3, Twist, Vimentin and E-Cadherin were found in 57 of 88 (64.8%), 48 of 88 (54.5%), 22 of 88 (20.0%)and 53 of 88 (60.2%), respectively. Significant differences in the expression of STAT3, Twist, Vimentin and E-Cadherin were all found among groups of pathologic metastasis, MRI metastasis and without metastasis, respectively (are P < 0.05). The expression of STAT3 was positively correlated to both expressions of Twist and Vimentin (r = 0.712 and 0.316, P < 0.01). CONCLUSION EMT plays important role in cervical lymph node metastasis in nasopharyngeal carcinoma. LMP-1 may be only as one of upstream factors associated with the EMT, but not the decisive factor for cervical lymph node metastasis.

Objective:To evaluate the clinical efficacy of the axillary approach in the treatment of scapular glenoid fracture.Methods:A retrospective analysis was performed of the 12 patients who had been treated for scapular glenoid fracture from November 2019 to April 2021 at Department of Upper Limb Orthopaedics, Zhengzhou Orthopaedic Hospital. They were 4 males and 8 females, aged from 30 to 75 years (mean, 53.5 years). According to the Ideberg classification, there were 2 cases of type Ⅰa, 9 cases of type Ⅱ and one case of type Ⅴa. All cases were treated through the axillary approach. Two patients complicated with anterior shoulder dislocation were treated with manual reduction under anesthesia before operation and the other 10 cases with special plate fixation through the axillary approach. The 3 patients complicated with fracture of greater tuberosity were fixated with a special plate through the lateral shoulder split deltoid approach. Constant-Murley score, visual analogue scale (VAS) and Hawkins grading were used at the last follow-up to evaluate shoulder function, pain and stability after operation.Results:All patients were followed up for 9 to 20 months (mean, 14.4 months). The operation time ranged from 55 to 110 min (mean, 76.3 min), intraoperative bleeding from 60 to 160 mL (mean, 103.8 mL), and hospital stay from 8 to 14 d (mean, 11.1 d). All incisions healed primarily and all scapular glenoid fractures got united 6 months after operation. The last follow-up showed no shoulder instability, neurovascular injury or internal fixation failure. At the last follow-up, the range of motion of the shoulder was 159.2°±26.1° in forward bending, 156.7°±29.6° in abduction, 48.3°± 15.3° in external rotation (neutral position), and 73.3°±12.3° in internal rotation (neutral position), and the Constant-Murley score was (94.0±5.3) points. The range of motion of the shoulder and Constant-Murley score were significantly improved compared with those before operation (10.8°±11.6°, 7.5°±11.4°, 5.8°±10.0°, 42.5°±16.0° and 4.9±4.0, respectively) (all P<0.05). The VAS score was 0 in 11 patients and 2 in one patient at the last follow-up. Conclusion:The axillary approach is feasible for the treatment of scapular glenoid fracture, because it is hidden and less invasive, leading to good clinical outcomes.

Objective:To investigate the efficacy of fixation with cannulated screws alone via the Kocher approach in the treatment of adult humeral capitulum fractures.Methods:From August 2016 to August 2020, 16 patients with humeral capitulum fracture were treated at Department of Upper Limb Orthopedics, Zhengzhou Orthopaedic Hospital. They were 10 males and 6 females, aged from 36 to 62 years (average, 45 years). The left side was affected in 10 cases and the right side in 6. According to the Ring classification, 3 cases were type Ⅰ, 3 cases type Ⅱ, 6 cases type Ⅲ, and 4 cases type Ⅳ. All patients were treated with the Kocher approach on the lateral side of the elbow. After reduction under direct vision, the fractures were fixated temporarily with Kirschner wires and finally with cannulated screws. On the second postoperative day, the patients started active flexion and extension of the elbow joint and took indomethacin orally to prevent heterotopic ossification. At the last follow-up, the curative efficacy was evaluated according to the Mayo elbow performance score (MEPS). The flexion and extension of the elbow joint and the rotation of the forearm were also recorded.Results:All patients were followed up for 10 to 19 months (mean, 14.3 months) after surgery. Bony union was achieved after 7 to 12 monthes (average, 11.3 monthes) in all the 16 patients, 2 of whom developed heterotopic ossification. By the MEPS evaluation at the last follow-up, 8 cases were excellent, 6 good and 2 fair, scoring an average of 89.5 points (from 73 to 95 points). At the last follow-up, the elbow flexion ranged from 80° to 130° (averaging 113°), extension from 5° to 30° (averaging 15°), forearm pronation from 62° to 75° (averaging 67°), and forearm supination from 50° to 90° (averaging 75°).Conclusion:When the fracture ends are exposed through the lateral Kocher approach, the fracture fragments fixated with cannulated screws only, and the patients encouraged to start elbow joint exercises in the early stage, the treatment of adult humeral capitulum fractures can result in satisfactory curative effects.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.
