As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Objective To evaluate the application value of X-ray,echocardiogram,pulmonary perfusion scintigraphy,EBCT,Magnetic resonance Pulmonary angiography in diagnosis of PTE.Methods Twenty-five consecutive patients clinically diagnosed of having PTE were examined from july 2003 through March 2004. Patients underwent X-ray chest plain film, echoeardiogram, electronic beam computed tomographie (EBCT)angiography,ventilation-perfusion (V-P)seintigraphy,Magnetic resonance Pulmonary angiography (MRPA)and puhnonary angiography according to a strict diagnostic protocol.Two of the independent readers reviewed the pulmonary angiography and record all of the lobe and segmental involved in PTE and compared with other image method.Results Pulmonary angiography:all of the patients success underwent the technique,the pulmonary artery branch with PTE was in 556 of 775 branches (71.7%). Chest radiography had hints of diagnosis in 12 of 25 patients.Nine patients diagnosed with echocardiogram. Right heart enlargement was in 21,and pulmonary hypertension in 18.V-P scintigraphy revealed 247 segmental involved with PTE of 500 (52.0% ),and the sensitivity was 64.66% compare with the pulmonary angiography.There were 523 pulmonary branches involved PTE with EBCT pulmonary angiograpy of 775 branches,and the sensitivity was 94.06%.MRPA: 8 of 10 patients succeed in the technique, 155 branches of 248 were detected with PTE(62.5% ),the sensitivity was 81.29%.Conclusions EBCT is a high sensitivity method in diagnosis of PTE.Chest radiography and echocardiogram are the first-line modality of PTE.V-P scintigrapby is the valid compensation in diagnosis subsegmental pulmonary artery with PTE when EBCT miss diagnosis.Gd-CE-MRPA may be the second-line modality in diagnosis of PTE.

OBJECTIVETo explore a new technique for repair of alveolar cleft by sutural distraction osteogenesis.

METHODSNine 8-weeks mongrel dogs were used in this study, three being in the control group, six in the experimental group. Alveolar cleft model was created surgically in all animals. Two weeks later, a U-shaped distractor made of Ni-Ti memory alloy wire was insterted into the premaxilla to distract the mid-premaxillary suture. When the premaxilla of the cleft side approached the ipsilateral maxilla, periosteoplasty of the alveolar cleft was performed. The distractor was removed at two weeks after periosteoplasty. The results were evaluated clinically, radiographically, morphologically and histologically.

RESULTSThe cleft model in dogs was stable and similar to the human alveolar cleft. In experimental dogs, the premaxilla was moved gradually toward the maxilla so that the cleft was closed. The distracted mid-premaxillary suture showed a gradually widened traingle, with its tip being posterior. The density of the distracted traingle suture was increased gradually. Bony repair was achieved completely at the cleft three months post-periosteoplasy. The morphology of the mid-premaxillary suture was restored.

CONCLUSIONThe alveolar cleft could be repaired by the technique of mid-premaxilla suture distraction.

Objective To observe the effect of different doses of atorvastatin combined with probucol on contrast induced acute kidney injury (CIAKI) and serum uric acid in elderly patients.Methods Totally 121 cases admitted for coronary angioplasty were randomly divided into three groups.In standard combining treatment group (n＝35),atorvastatin 20 mg qn and probucol 0.25 g,tid were given with no loading dose intake before angioplasty.In intensively combined treatment group (n＝41),atorvastatin 40mg qn and probucol 0.25 g,tid were given with a loading dose of atorvastatin 40 mg and probucol 0.5 g at 2 hours before angioplasty.In intensive atorvastatin therapy group(n＝45),atorvastatin 40 mg qn were given,with a loading dose of atorvastatin 40 mg 2 hours before angioplasty.All patients were then evaluated 24 hours before and after angioplasty procedure,and their blood urea nitrogen (BUN),serum creatinine (Scr),serum uric acid (SUA),estimated glomerular filtration rate (eGFR) by modified diet in renal disease study (MDRD) method were tested.The serum and urine at 24 hours before and after operation were collected.Neutrophil gelatinase associated lipocalin (NGAL) were determinated by enzyme linked immunosorbnent assay (ELISA) method.Results After operation,eGFR was decreased in standard combining treatment group [(76.2±14.3) ml· min-1 · 1.73 m-2 vs.(71.9±17.9) ml· min-1 · 1.73 m-2,P＜0.05],while Scr,eGFR and uNGAL showed no changes in intensively combining treatment group and intensive atorvastatin therapy group (P＞0.05) ; BUN in the two groups was decreased [(5.6± 1.4)mmol/L vs.(4.7±0.9) mmol/L,(5.3±1.2) mmol/L vs.(4.8±1.2) mmol/L,P＜0.01,P＜0.05].SUA was reduced in intensively combining treatment group (P ＜ 0.05).uNGAL was increased in standard combining treatment group (P ＜ 0.05).Conclusions For elderly patients,intensive atorvastatin therapy and combining intensive treatment can both improve CIAKI.Only combination and intensive treatment benefit for decrease of uric acid.

Purpose: A phase II study was conducted to evaluate the safety and efficacy of preoperative, intra-arterial perfusion of epirubicin, etoposide, and oxaliplatin combined with oral chemotherapy S-1 (SEEOX) for the treatment of type 4 gastric cancer. Materials and Methods: A single-center, single-arm phase II trial was conducted on 36 patients with histologically proven type 4 gastric cancer without distant peritoneal or organ metastasis. Patients received 3, 21-day courses of SEEOX preoperative chemotherapy. The primary endpoint was overall survival (OS) and the secondary outcomes assessed were chemotherapeutic response, radical resection rate, pathological regression, toxicities, postoperative morbidity, and mortality. Results: All patients were at an advanced stage of cancer (stage III or IV) and completed the entire course of treatment. Based on changes in tumor volume and peritoneal metastasis, the objective response rate was 55.6% (20/36; 95% confidence interval [CI], 38.5%–72.6%) and the disease control rate was 69.4% (25/36; 95% CI, 53.6%–85.3%). The radical resection rate was 75% (27/36; 95% CI, 60.1%–89.9%) and the proportion of R0 resections was 66.7% (21/36; 95% CI, 50.5%–82.8%). The pathological response rate was 33.3%, of which 13.9% showed complete pathological regression. The median survival was 27.1 months (95% CI, 22.24–31.97 months), and the 2-year OS was 48.5% (95% CI, 30.86%–66.1%). Conclusions Preoperative SEEOX is a safe and effective treatment for type 4 gastric cancer. Based on these preliminary data, a phase III study will be conducted to confirm the superiority of this regimen over standard treatment.Trial Registration: ClinicalTrials.gov Identifier: NCT02949258

OBJECTIVETo study the effect of cesarean section birth based on different indications on attentiveness in school children.

METHODSA total of 308 school children were assigned to three groups according to their birth model: natural delivery (n = 105), cesarean section due to social factors (n = 101) or medical factors (n = 102). The integrated visual and auditory continuous performance test (IVA-CPT) was performed for assessing attentiveness.

RESULTSThe IVA-CPT demonstrated that there were significant differences in the quotients of combination control, auditory response control, combination attention, auditory attention, visual attention, auditory vigilance, visual concordance, visual vigilance and visual attention among the three groups (p<0.05). The results of the IVA-CPT in the group of cesarean section due to medical factors was obviously poorer than that of the natural delivery group and the group of cesarean section due to social factors. However no significant differences were observed between the groups of natural delivery and of cesarean section due to social factors.

CONCLUSIONSCesarean section itself has no significant impacts on attentiveness in school children, while medical indications for cesarean section may contribute to major cause of attention deficit disorder.

OBJECTIVETo observe the mechanism of the optimized traditional acupuncture prescription for accouchement on cervical ripening based on the molecular biology by observing related indices of cervical ripening in late-stage pregnant rats.

METHODSTwenty initial pregnant Wistar rats were randomly divided into an electroacupuncture (EA) group (n = 10) and a model group (n = 10), and other 10 non-pregnancy female rats with same lot were selected as a blank control group. EA group was treated with the optimized traditional acupuncture prescription for accouchement on the 20th day of pregnant, which performed EA at bilateral "Hegu" (LI 4) for 20 min and then at bilateral "Sanyinjiao" (SP 6) for 5 min with 2 Hz/50 Hz sparse-dense wave, while the other groups without acupuncture intervention. The contents of matrix metalloproteinase 9 (MMP-9) and interleukin 8 (IL-8) in cervix tissue were detected by ELISA method.

RESULTSCompared with the blank control group, the contents of MMP-9 and IL-8 in the model group were increased significantly (both P < 0.01). Compared with the model group, the contents of MMP-9 and IL-8 in the EA group were increased significantly (P < or = 0.05).

CONCLUSIONOptimized traditional acupuncture prescription for accouchement can increase the contents of MMP-9 and IL-8 in cervix tissue of late-stage pregnant rats so as to promote cervical ripening, and the mechanism of EA in promoting cervical ripening is explained from the perspective of molecular biology.
