Objective To establish better reaction factors for rep-PCR and to investigate if the extended spectrum ?-lactamase(ESBL)+ Escherichia coli isolated from different patients in the respiratory ward have the same origin by using rep-PCR.Methods The ESBL confirmation was taken by double disc confirmatory test.The susceptibility testing was performed with K-B test.By applying the widespread enterobacter repetitive intergenic consensus as a primer,the stains were typed by rep-PCR following electrophoresis in agarose gel.Results The analysis of the PCR productions indicated that it would create useful DNA ban-prints and all these 22 ESBL(+)Escherichia coli strains were of three origins.Conclusion The method of rep-PCR is practical for epidemiological research in nosocomial infection.

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.

BACKGROUND: The assessment of chronic nerve root injury is mainly depend on indirect evidences of imaging results.OBJECTIVE: This study is designed to find out the relationship between the degrees of the pathological changes of nerve roots and motor evoked potential (MEP) changes due to chronic compression.DESIGN: A self-controlled trial with animals as subjects.SETTING: Spine Surgery Department of the Second Clinical Hospital of Jinan University.MATERIALS: The trial was completed in the Spinal Surgery Department of the Second Clinical Hospital of Jinan University from October 2001 to May 2003. The subjects were 30 healthy cats of either gender weighing 3 to 5 kg.INTERVENTIONS: The compression model was established by wedging a Ⅴ-shape bone flap into the right intervertebral foramens between C7, C8 and T1 vertebrae. The left foramens served as controls. The cats underwent CT examination on the 2nd, 4th, 8th and 12th postoperative week to show the foramen changes. Six randomly selected cats underwent magnetic stimulation MEP each time on the 2nd, 4th, 8th, 12th and 24th week. The injuries to the compressed nerve roots were assessed according to Mackinnon Standard and they were compared with the MEP wave.MAIN OUTCOME MEASURES: Whether the superficial magnetic stimulated MEP monitoring result was in correspondence with the pathological changes of the chronically compressed nerve roots.RESULTS: The MEP did not show any abnormal changes for Grade Ⅰ injury prolonged to 9.6- 10. 2 ms. There was almost no evoke potential at all stimulation points for grade Ⅴ nerve root injury.CONCLUSION: That the injured nerve root presents dysesthesia and normal MEP results suggests grade Ⅰ injury. Prolonged latency including prolonged F wave suggests grade Ⅱ injury. And additional amplitude decrease together with widened and unclassifiable waves implies the injury be grade Ⅲ. The prominent features of grade Ⅳ nerve injury is much more decreased amplitudes and more prolonged latency. For grade Ⅴ injury there is always disappearance of whole MEP or some potential components. The superficial magnetic stimulated MEP monitoring results are in correspondence with the pathological changes of the nerve roots due to chronic compression, which means MEP monitoring results could serve as the quantitative indication to pathological changes of nerve injury.

This paper was aimed to analyze and study the process of Turmeric fine pulverizing; and the powder properties of Turmeric ultra-micro powder after the process. Based on d50, the powder properties of Turmeric ultra-micro powder were summarized by using orthogonal design to select the optimal Turmeric fine pulverizing. Compari-sons were made on powder properties, such as exterior characters, IR spectra, fluidity and hygroscopicity before and after fine pulverizing. The results showed that optimal fine pulverizing process was determined based on orthogonal design. The conditions were that the material was 1 200 g, with water of 5.5% and crushing for 40 min. Compari-son of powder properties of Turmeric powders before and after fine pulverizing showed that as the diameter of the particle decreased. Turmeric particle gradually showed signs of aggregation. At the same time, granular sensation disappeared;the color turned lighter;powder became finer;fluidity was reduced;balanced hygroscopic capacity el-evated. Although the chemical composition and molecular structure had not changed;initial velocity and capacity of hygroscopicity increased, acceleration declined. It was concluded that Turmeric fine pulverizing was a convenient, reliable and practical process, with small size of particle. It can be used for Turmeric fine pulverizing. The compre-hensive evaluation showed that ultrafine powder four as the optimum powder.

Objective To report two cases of Nagashima-type palmoplantar keratoderma(NPPK), and to identify mutations in the SERPINB7 gene. Methods Clinical data were collected from two patients with NPPK and their parents, and peripheral blood samples were obtained from the two patients, their parents and 200 unrelated healthy controls. Genomic DNA was extracted from these blood samples. PCR was performed to amplify 8 exons and their flanking sequences of the SERPINB7 gene followed by DNA sequencing. Results A homozygous mutation (c.796C > T), which led to the formation of a premature termination codon at amino acid position 266 (p.R266*), was identified in both of the two patients. However, the patients′ healthy parents were heterozygous carriers of the mutation(c.796C > T). No mutation was found in the unrelated healthy controls. Conclusion The mutation c.796C > T in the SERPINB7 gene may be responsible for NPPK in the two patients.

Objective To investigate the efficacy of endoscopic intranasal structure reconstruction surgery for rhinogenous headache. Methods 82 cases of rhinogenous headache were given endoscopic intranasal structure reconstruction. Compared VAS scores before and 6 months after treatment, counted the effective rate. Results Among the 82 patients, 69 patients(84. 1%) were cured, 8 cases (9. 8%) were of obvious effect, 5 cases (6. 1%) were invalid, and the total efficiency was 93. 9%. VAS scores of the mucosal contact headache group before treatment were greater than that of the sinus headache group (P<0. 05). Compared with VAS scores before treatment, both of the two groups had lower VAS scores after treatment (P<0. 05), but there was no significant difference between the two groups after treat-ment (P>0. 05). Conclusion Endoscopic surgical operation can remove the extrusion of the nasal cavity and paranasal sinuses and factors of nasal congestion, and then reconstruct normal anatomical structure of nasal cavity, thus restoring normal function of paranasal sinuses. It has good therapeutic effect on rhinogenic headache.

Objective To compare and analyze the curative effects of mediopatellar plica syndrome under different therapies. Methods 147 patients with mediopatellar plica syndrome were enrolled in the study from January 2011 to January 2015 and divided into three groups refer to treatment: Group A, B and C. Each group was also divided in the youth group and the mid-age group. Different treatments were used in the three groups. Group A: drug therapy and physicotherapeutics; Group B: intraarticular injection regularly; Group C: arthroscopic surgical treatment. All patient conditions were assessed with Lysholm score. Results All patients received an average of 11 (9 ~ 13) months follow-up. No blood-vessel and nerve injured and infection occurred. Before receiving treatment, difference in Lysholm score of the three groups showed no statistical difference (F = 0.08, P = 0.926); after treatment, difference revealed significant difference (F = 15.48, P = 0.001). Compared with those before operation and after operation among the three groups, the Lysholm score was improved (tA = 3.43, tB = 6.74, tC = 7.99, P = 0.001). In the rangeability of Lysholm score, the Group C > B > A (F = 66.43, tAB = 5.97, tAC = 11.52, tBC = 5.55, P = 0.001);The general youth group > the general mid-age (t = 7.91, P = 0.001). Conclusion The best therapeutic method for mediopatellar plica syndrome is the arthroscopy. As for mid-age patients, it is necessary to inform them of possibility that prognosis is not well in preoperative planning.

Objective To assess the differences in the specificity and the sensitivity in detecting specific IgM by indirect ELISA and capturing-ELISA methods,and to analyze the possible causes of those differences.Methods The HBc-IgM and EHF-IgM level in serum samples from activity Hepatitis B patients and hemorrhagic fever patients with renal syndrome were determined by both indirect-ELISA and capturing-ELISA methods,and the differences in the positive rate,positive threshold value and the specificity between those two methods were compared. Results Specific murine IgM diluted in PBS were detected by indirect-ELISA and capturing-ELISA,and the specificity and sensitivity of those two methods were similar.Results showed that sensitivity of indirect-ELISA was lower than capturing-ELISA in detecting specific IgM in serum from patients with activity Hepatitis B and hemorrhagic fever patients with renal syndrome.The IgM level in hepatitis B and hemorrhagic group treated with thioglycol became negative detected by those two methods,suggesting that both of them have the anti-IgM epitope-specificity.Cross reaction results demonstrated that the reagent detecting IgM from the two methods had the specificity to the specific antigen. Conclusion It is recommended to detect IgM level by capturing-ELISA method for the early diagnosis of acute infectious disease,pathological changes,immune reaction and prognoses of chronic continuous infectious disease.Applying the indirect-ELISA method to detect IgM level to diagnose acute infectious disease is to discuss in the future.
