The authors adopted acupuncture plus auricular electro-acupuncture to treat 38 cases of dysmenorrhea belonging to qi stagnation and blood stasis pattern, the better therapeutic effect was achieved, with the effective rate of 97.4%.

50Gy gave better survivals.Conclusion Age,tumor histology,ex- tent of resection,interval time of postoperative radiotherapy and the dosage of target were related to survival.

Abstract: Objective　To understand the distribution and drug resistance of bacteria in clinical blood culture specimens in Ningxia in recent years, and to provide a basis for the prevention and treatment of bloodstream infection diseases. 　　　Methods　The blood culture isolation bacteria and drug resistance of Ningxia bacterial resistance monitoring network hospitals from 2018 to 2020 were statistically analyzed by WHONET5.6 software. Results　In the past three years, a total of 6 757 strains of bacteria were isolated from blood samples, including 3 697 strains (54.7%) of gram-negative bacteria and 3 060 (45.3%) of gram-positive bacteria. Among the gram-negative bacteria, Escherichia coli (2 074 strains,30.7%), Klebsiella pneumoniae (696 strains), Pseudomonas aeruginosa (139 strains), and Acinetobacter baumannii (121 strains). Among the gram-positive bacteria, coagulase-negative Staphylococcus (1 691 strains,25.0%), Staphylococcus aureus (442 strains), Streptococcus spp. (431 strains), Enterococcus spp. (379 strains). Resistance to Escherichia coli and Klebsiella pneumoniae was 56.6% and 22.6% against third-generation cephalosporins, and resistance to carbapenems was 1.0% and 3.7%, respectively. Pseudomonas aeruginosa and Acinetobacter baumannii were resistant to carbapenems at 9.0%（12/139） and 80.7%（71/121）. Methicillin-resistant Staphylococcus aureus (MRSA) was detected at 26.8%, methicillin-resistant coagulase-negative Staphylococcus was detected at 70%, and no Staphylococcus bacteria resistant to vancomycin and linezolid were found. For three years, only 1 strain of vancomycin-resistant Enterococcus faecalis was detected, and no linezolid-resistant Staphylococcus and Enterococcus were detected. Conclusions　Ningxia clinical blood specimen isolates of Escherichia coli, coagulase-negative Staphylococcus, and Klebsiella pneumoniae are more common. Among them, the resistance rate of Escherichia coli and Klebsiella pneumoniae to the third generation of cephalosporins is relatively stable, and the resistance rate to carbapenems is low. Acinetobacter baumannii is highly resistant to carbapenems, and methicillin-resistant Staphylococcus aureus detection rates are on the rise and should be closely monitored.

OBJECTIVE: To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors. METHODS: The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gender and height on the latency of postural evoked response were analyzed. RESULTS: (1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle; under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tibialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The latency in male was longer than that in female. (4) The latency gradually increased with the increase of height. CONCLUSION In the postural evoked response, different perturbations, gender and height have significant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.

The external defibrillator is an emergency instrument used very widely in clinics. It plays an important role in rescuing ventricle fibrillation (VF) patients. We have designed an external defibrillator using the truncated exponential biphasic waveform. The system consists of three parts: the ECG collection module, the control module and the defibrillator module. They are introduced respectively, listing the main problems and the methods to solve them. Some experiments have been done and the corresponding results are given.

According to the instruction of the operator, the designed programmable multichannel stimulator will deliver stimuli with an assigned amplitude and a proper width to the electrode-array in various modes. Each stimulation time is controlled by the internal timer of the MCU, while the stimulated electrodes' spatial parameter is controlled by the CPLD. Having abandoned conventional isolation using the transformer, we have adapted optical coupling and stable float ground connection to achieve the safety standard required by physiological measurements.

OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.

METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.

RESULTAccording to cultural method, Aspergillus flavus and Rhizopus oryzae were present in Massa Medicata Fermentata samples, while A. flavus and A. niger were present in fried Massa Medicata Fermentata samples. In contrast, 5 species were obtained by PCR-SSCP technique, A. flavus was overlapped with fungal taxa derived from culture dependent method; A. ambiguu and A. s ivoriensis were dominant with relative abundance of 57% and 35% respectively, while the relative abundance of A. flavus was as low as 4%. None species was obtained from fried Massa Medicata Fermentata samples.

CONCLUSIONPCR-SSCP based on β-tubulin gene could distinguish fungi into species, culture dependent method combined with culture independent method could better understand the fungal composition associated with Massa Medicata Fermentata fermentation.
