Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

BACKGROUNDTo study the effect of human papillomavirus (HPV) 16 E6/E7 and TPA (12-O-tetradecanog-1-phorbol-13-acetate) on malignant transformation of human embryo oral tissue.

METHODSRecombinant plasmid with HPV 16 E6/E7 was constructed and transfected into human embryo oral tissue. The oral tissue with HPV 16 E6/E7 gene or without the gene was inoculated into the hypophloeodal of right shoulder in scid mice, respectively. The study was conducted in four groups: the first group was the oral tissue transfected plasmid with HPV 16 E6/E7 plus TPA, which were inoculated into 8 scid mice; the second group was only oral tissue transfected with plasmid with HPV 16 E6/E7 into 6 scid mice; the third group was normal oral tissue plus TPA inoculated into 6 scid mice, and the final group was only normal oral tissue inoculated into 5 scid mice. Three days after inoculation, TPA was injected at the left shoulder of the mice once a week. Twelve weeks after inoculation, tumor was found in 7 scid mice from the first group. HPV 16 E6/E7 gene in tumor tissues was analyzed by PCR.

RESULTSThe rate of tumor formation was 7/8 in the first group; no tumor was found in the other groups. Pathological diagnosis of the tumor was fibrohistiocytoma. HPV 16 E6/E7 gene was detected by PCR in tumor tissues.

CONCLUSIONWith the cooperating action of TPA, human oral tissue containing HPV 16 E6/E7 gene could cause malignant transformation in scid mice.

Objective To investigate the impact of age on patients with metabolic syndrome (MS) and normal persons. Methods Data was gathered from 8280 persons including 4873 males and 3407 females who were randomly selected. All subjects were devided into normal group and MS group. According to the interval of ten years, the subjects were devided into seven age groups, to calculate the difference of impaired fasting glycaemia (IFG) between patients with diabetes mellitus (DM) and normal people, as well as the related portions. Results (1) The risk of IFG and DM appeared to be different among age groups among the target subjects as well as in the normal and the MS groups (P<0.05). (2) Among the whole subjects, the overall prevalence of IFG was increasing with age. The prevalence of DM had an increasing trend with age augment in 20-79 years group, whereas a decreasing trend appeared in people over 80 years of age. (3) For normal persons, the prevalence of IFG and DM were all increasing with age augment in 20-79 years group, and then decreasing with age augment in the over-80-years group. (4)For MS patients, the prevalence of IFG had an increasing trend with age augment in 20-69 years group, whereas a decreasing trend appeared in people over 70 years of age. There was no tendency of variation with age augment in DM.Conclusions (1) For normal persons, high prevalence rates of IFG and DM were correlated to age augment, especially in senior persons. (2) For MS patients, high prevalence of IFG was also correlated to age augment, but no association between prevalence of DM and age augment was seen. (3)Age from 70 to 79 years appeared to be in high risk with MS.

Objective To study the characteristics of the variation of antigen epitopes and quasispecies group in the HIV-1 viruses in Henan province in China. Methods The region of the p17-p24 of the HIV-1 gag gene was amplified by nested polymerse chain resction(PCR), purified products were cloned into the vector, the obtained were analyzed by MEGA soft wares. Results B' subtype strains were predominant in Henan province, the mutations in antigen epitypes of the p17 region of the gag gene focus on E62g(55.8% ) ,Y79f(48.9% ) ,T84V (48.9), I44V(44.2%), the p24 region had not found the distinct mutation. Conclusion Both the PCR sequences and clone strains sequences demonstrated that four antigen epitopes mutations in p17 region of the HIV B' subtype gag gene, and the region of p24 was more conservative,which was suitable for development of the epitope vaccien.

Objective To study the characteristics of the variation of the V3 loop tip motifs and the drug resistance in the primary treatment patients. Methods The partial region of the HIV-1 env and pol gene in 51 samples was amplified by nested polymerase chain reaction (PCR) ,purified products were cloned into the vectors, the obtained were analyzed by MEGA soft wares. Results The V3 loop tip motifs had four types in our study ( GPGR, GPGQ, GPGK, GQGR); the study on the drug resistance in primary treatment patients, showed that there were not major resistance associated with PI, and the resistance were minor mutations in protease gene. In the RT region, there were nine resistance mutants were single NRTIs or NNRTIs. Conclusion The GPGR which was the typical western V3 loop tip motifs attained to 44.44%.This results showed that the percentage of primary drug resistance was still low in our study region,suggesting no need for genotyping detection in blood donor patients before primary therapy.

OBJECTIVETo evaluate the clinical effect of combination of acupuncture, cupping and medicine for treatment of fibromyalgia syndrome.

METHODSBy using multi-central randomized controlled method, 186 cases were randomly divided into an acupuncture combined with cupping and western medicine group (group A), an acupuncture combined with cupping group (group B) and a western medicine group (group C) and treated continuously for 4 weeks. The treatment of acupuncture combined with cupping was produced by acupuncture at five mental points and moving cupping on the Hechelu of the back, once evrey other day, thrice each week, and the western medicine therapy by oral administration of Amitriptyline, once each day. The scores of McGill Pain Questionnaire (MPQ), the amount of tenderness point and the time of producing effect were compared and the therapeutic effects were assessed with the Hamilton Depression Scale (HAMD).

RESULTSThe cured and markedly effective rate was 65.0% (39/60) in the group A, which was superior to 15.9% (10/63) in the group B and 16.1% (9/56) in the group C (both P < 0.001). After treatment, the scores of MPQ and HAMD and the amount of tenderness point all decreased in the three groups, group A being significantly better than group B and group C, and the time of producing effect in the group A was more earlier than those in the group B and the group C.

CONCLUSIONThe therapeutic effect of combination of acupuncture, cupping and medicine on fibromyalgia syndrome is superior to that of the simple acupuncture combined with cupping or the simple medicine.

OBJECTIVETo study the surgical treatment effect and factors influencing prognosis of recurrent carcinoma within gastric remnant.

METHODSFrom 1990 to 2003, clinical data of 60 patients underwent surgical operation again because of recurrence carcinoma within gastric remnant after radical resection were reviewed retrospectively.

RESULTSThe mean survival time was 32.6 months and the median survival time was 27.0 months. Thirty-seven patients (61.7%) received radical resection with the mean survival time of 45.0 months. Twenty-three patients received palliative treatment with the mean survival time of 12.7 months (P< 0.001). Univariate analysis showed that the clinical stages, pathologic classification, radical resection, peritoneal seeding, liver metastasis, the expression of CD44v6, PCNA and MVD were significantly correlated with survival time (P< 0.01), but were not correlated with sex,age,recurrence time after the first operation (P> 0.05). Multivariate analysis revealed that the clinical stages, peritoneal seeding and radical resection were independent prognostic factors.

CONCLUSIONSThe clinical stages, peritoneal seeding and radical resection are independent prognostic factors of recurrent carcinoma within gastric remnant. The radical resection maybe the most effective way to treat the recurrent carcinoma within gastric remnant.

OBJECTIVETo explore the anatomic features of mesoesophagus in combined thoracoscopic and laparoscopic esophagectomy with three-fields lymphadenectomy.

METHODSClinical data of 67 patients undergoing thoracoscopic and laparoscopic esophagectomy with three-fields lymphadenectomy from July 2011 to September 2012 were analyzed retrospectively. All the patients underwent three-fields lymphadenectomy. Proper surgical planes were selected according to anatomy of mesoesophagus. Thoracoscopic surgical space was bounded on azygotic vein and divided into upper and low esophageal triangle. Pancreas was the key anatomical mark for laparoscopic gastric dissection, and peripancreatic space was the natural laparoscopic surgical plane. Prevertebral fascia was bottom surface of neck dissection and carotid sheath was the boundary of two sides.

RESULTSThe median operative time was 251.6 min (range, 220 to 320 min). The median operative blood loss was 105.6 ml (range, 40 to 320 ml). The median number of lymph nodes dissected was 29.1 (range, 13 to 46, totally 1949). There was no perioperative death. Sixty-six patients were followed up with a mean follow-up time of 8.2 months (range, 2 to 14 months). Postoperative complications included reflux esophagitis in 10 and anastomotic stenosis in 3 cases.

CONCLUSIONIt is safe and more radical for minimally invasive esophagectomy that overall concept of minimally invasive anatomy of mesoesophagus is applied to identify the anatomic plane and landmark during operation.

Fluorescent carbon dots(CDs)were synthesized via a solvothermal method with citric acid and urea as raw materials,and ethylene glycol as reaction solvent.The micromorphology,crystal structure,elemental composition,surface functional group,and optical property of as-synthesized CDs were characterized.The excitation-dependent fluorescence property of CDs was investigated,and the effects of synthesis conditions including reaction temperature,reaction time and raw materials on excitation and emission wavelengths of the CDs were also discussed.Then,a series of CDs-based fluorescent composites were prepared by combining CDs with starch,nano-silica,montmorillonite,kaoline,kieselguhr and magnesium oxide,respectively.Finally,the CDs-starch composites were used for latent fingerprint development on smooth substrates,and the qualitative as well as quantitative evaluation of the contrast,sensitivity and selectivity in fingerprint development were also made.Enhanced development of latent fingerprints was thus achieved by the aid of the excitation-dependent fluorescence property of CDs-starch composite combined with the optical filtering technique,which could decrease the background noise interference to a great extent.Experimental results showed that,the contrast between fingerprint(developing signal)and substrate(background noise)was obvious,exhibiting a strong contrast;the minutiae of papillary ridges were clear,indicating a high sensitivity;the adsorption between CDs-starch composites and fingerprint residues was specific,showing a good selectivity.
