There are many deficiencies in forensic traumatic molecular markers detected by the techniques of traditional immunohistology and molecular biology, because these markers are isolated and obscure of the mechanism of interaction. The imaging mass spectrometry (IMS) is more suitable for the forensic molecular markers using function of screening, analysis and graphical representation. In this paper, the techniques and the latest research in screening and identification of typical molecular markers by IMS based on matrix-assisted laser adsorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) are reviewed. And its application values in forensic injury are discussed.

The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

Objective To study the clinical effect of herbs of replenishing qi, nourishing yin and promoting blood combined with western medicine on symptoms and hemorrheology indexes of aged diabetic mellitus (DM). Methods Sixty cases with DM-2 were randomly divided into two groups. The treatment group was given herbs combined with western medicine and the control group was given western medicine treatment only. The treatment course was 1 month. The clinical symptoms, blood glucose and hemorrheology indexes were observed in both groups. Results There were 11 marked effective cases, 15 effective cases and 4 ineffective cases in treatment group, while 2, 12 and 16 cases in control group. The total effective rate was 86.7% in treatment group and 46.7% in control group. There was a significant difference between the two groups. The whole blood viscosity, platelet aggregation, D-dimer and fingernail microcirculation were significantly improved in the treatment group. Conclusion The herbs of replenishing qi, nourishing yin and promoting blood combined with western medicine can improve the clinical symptoms and hemorrheology of aged DM.

0.05). Conclusion The g.168_185del polymorphism of the promoter in DJ-1 gene does not a significant risk factor for PD in this population.

Objective To investigate the clinical manifestation and diagnosis of Hashimoto thyroiditis (HT). Methods 45 HT patients diagnosed by fine needle aspiration cytology (FNAC) were enrolled in this study. Their medical history, clinical parameters, data of laboratory examination, colour doppler ultrasonic image and FNAC were analyzed. Results This disease was more common in women than in men, and most of cases occurred during 35～50 years old. Almost all cases had the symptoms of thyromegaly and laryngopharynx malaise. The patients had normal thyroid function, hypothyroidism or hyperthyroidism. The levels of both antithyroid globulin antibody and antithyroid microsome antibody increased in 39 cases. The ultrasonic imaging features of thyroid were such as following: diffusive nonhomogenous hypoecho pattern in 19 cases, numerous hypoecho micronodes in 15 cases, hyperecho micronodes in 3 cases, and hyperecho bandlike echo pattern with swelling of neck lymph nodes in 8 cases. Conclusion Diagnosis of HD should put emphasis on a complete medical history, physical examination and necessary laboratory tests. Antithyroid auto-antibody assay and thyroid ultrasonic examination were very important for diagnosis of HD, and FNAC may be indispensable in suspected cases.

Objective:To explore the effect of stage target intervention on mental state, quality of life and prognosis of spontaneous cerebral hemorrhage, so as to provide reference for improving the quality of life and prognosis of patients with spontaneous cerebral hemorrhage.Methods:A total of 261 patients with spontaneous cerebral hemorrhage from June 2017 to June 2019 in Beijing Union Hospital were selected as the research subjects. Patients were divided into the observation group (131 cases) and the control group (130 cases) by the random number table method. The control group was treated with routine nursing intervention, and the observation group applied stage target intervention based on the control group. The psychological state, quality of life and prognosis of the two groups were evaluated by Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), modified Rankin Scale (mRS), Stroke Specific Quality of Life scale (SS-QOL).Results:There were no significant differences in SAS, SDS, mRS, SS-QOL before intervention between the two groups ( P >0.05) . After intervention, the scores of energy, family role, language, activity, emotion, personality, self-care ability, social role, upper limb function, work / labor and total scores of SS-QOL in the two groups were all increased ( P < 0.05), and the increase of energy, family role, language, activity, emotion, personality, self-care ability, social role, upper limb function, work / labor and total scores of SS-QOL in the observation group were higher than those in the control group, and the differences were statistically significant ( P < 0.05). After intervention, the scores of SAS, SDS and mRS were (42.07±4.14), (43.09±4.79), (3.06±0.42) points in the observation group and (51.83±4.65), (54.82±4.92), (3.57±0.50) points in the control group, and the differences were statistically significant ( t values were 17.912, 19.516, 8.925, P < 0.05). Conclusions:Stage target intervention can improve the anxiety and depression of patients with spontaneous cerebral hemorrhage, improve the quality of life, and reduce the incidence of poor prognosis.

Objective To introduce the research progress of the modern methods in evaluating de qi sensation in acupuncture and moxibustion, and to analyze the current research situation and major problems. Method The objective evaluation methods majorly used to estimate qi sensation were summarized. Result The currently used evaluation methods basically include scales and cerebral function imaging, while the rest methods are still in the beginning stage. Conclusion As a subjective feeling, de qi sensation is difficult to determine and quantify objectively, and there lacks an objective standard. The study on the mechanism of de qi sensation is relatively insufficient and superficial.

According to foreign and domestic standards of clinical quality and the author team’ experience summary of long-term clinical study, it has been found that quality control in clinical acupuncture operators is closely related to operator’s ability, good communication between doctors and patients, signature for informed consent, implementation of inclusion and exclusion criteria, practice of blind method and random concealment, patient’s compliance, standardized writing and keeping of CRF, management of instruments and consumables, and coordination and association between researchers. The implementation method of quality control in clinical acupuncture operators is explored by the clinical practice of the author team in “973” project, and analysis and discussion of the above key points.

ObjectiveTo assess the efficacy of subglottic secretion drainage for preventing ventilatorassociated pneumonia.MethodsData of relevant randomized controlled trials (RCT) from January 1991 to June 2010 were collected,and data were split into two groups,namely draining group and non-draining group.Meta analysis of ventilator-associated pneumonia was carried out for finding the incidence and mortality in patients with mechanical ventilation using the methods recommended by the Cochrane Collaboration.ResultsSeven RCTs met the inclusion criteria and 1647 patients were enrolled.Subglottic secretion drainage reduced the incidence of ventilator-associated pneumonia ( OR =0.45,95％ confidence interval [CI]:0.32 - 0.63 ),primarily by reducing early-onset pneumonia.But the mortalities of ventilator associated pneumonia were not significantly different between the two groups ( OR =1.03,95％ confi dence interval [CI]:0.75 - 1.41 ).ConclusionsSubglottic secretion drainage appeared effective in preventing ventilator associated pneumonia among patients expected to require ＞48 hours of mechanical ventilation,but the mortality was unchanged.

AIM: To evaluate the physiologic change of retinal thickness during pregnancy.
METHODS:Forty cases ( 80 eyes ) were included two groups:40 eyes ( 20 cases ) in healthy pregnant women group (including in the second and last trimester), and 40 eyes (20 cases) in healthy nonpregnant women group ( control group ) . The macular volume, average thickness, central subfield thickness and retinal thickness of other parafoveal areas were measured by optical coherence tomography scan.
RESULTS: The macular volume was 10. 06±0. 41mm3 and 9. 87±0. 30mm3 in healthy pregnant women group and control group respectively. The average thickness was 279. 43±10. 86μm and 274. 25±8. 07μm in healthy pregnant women group and control group respectively. The central subfield thickness was 235. 15±15. 05μm and 233. 00±15. 81μm in healthy pregnant women group and control group espectively. Statistically significant difference was found in macular volume and average thickness (P<0. 05). The retinal thickness of 8 parafoveal areas in healthy pregnant women group increased comparing with control group, but statistical significance was only found in superior-outer area and inferior-outer area(P<0. 05). OCT images of all cases were normal.
CONCLUSION:The macular retinal thickness increases during pregnancy in the second and last trimester. The physiologic change of retinal thickness should be considered when evaluating pathologic retinal disease of pregnant women.
