OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

Objective To investigate the expression of transforming growth factor?1(TGF-?1)in human colorectal carcinoma and its value for predicting the prognosis.Methods The expression of TGF-?1 and vascular endothelial growth factor(VEGF)was measured in specimens of 52 coloreetal cancers by immunohistoehemistry.The features of clinical pathology were analyzed and the follow-up of all patients were conducted.The correlation between the expression of TGF-?1 and the survival time was studied with Log-rank test.Results Of 52 patients,no expression of TGF-?1 and VEGF was observed in 11 and 14 patients,and the expression was noticed in 41 and 38 patients,respectively.There was a signifi- cant positive correlation between expression of TGF-?1 and expression of VEGF(x~2＝0.633,P＜0.01). Furthermore,the expression of TGF-?1 was significantly correlated with Dukes staging(x~2＝19.866,P＜0.01)and metastasis of lymph nodes(x~2＝13.152,P＜0.01).The 3-year overall survival rates(OSR)in all patients was 49.1% and the 3-year OSR of patients with and without expression of TGF-?1 were 20.5% and 69.2% respectively(x~2＝11.64,P＝0.0006).Conclusion The expression of TGF-?1 could be served as an important predicator for prognosis of coloreetal carcinoma.

Telemedicine is one of the five key components of the "Internet Plus Healthcare".Due to its high speed,real-timeness,low cost,and wide spread,telemedicine is highly feasible in the prevention and control of major infectious diseases.This article introduces the practiceof telemedicine in Peking Union Medical College Hospital during the cornavirus disease 2019(COVID-19)epidemic,during which the network resources were applied to break geographical restrictions and resolve communication barriers between hospitals and departments.This article summarizes the telemedicine application before,during and after COVID-19 control and elucidates how to build a telemedicine prevention and control system for infectious diseases,with an attempt to further improve telemedicine and is application in the public health emergency system in China.

OBJECTIVETo investigate the know gene types of main wild type measles virus strains and take measures to control measles in Jilin Province.

METHODSGenetic characterization of 9 measles viruses isolated from 72 throat swabs or urine specimens of measles patients using CDW(150) cells line was studied in Jilin Province in 2005.

RESULTSSequence analysis of 450 nucleotides of COOH-terminal of nucleoprotein (N) genes of 9 isolates indicated that all were members of H(1) genotype, in which there are 7 strains of H1a and 2 strains of H1b, the H1a subgroup differed from H1b by 2.0% approximately 3.5% at the nucleotide level in the COOH-terminal of the N gene.

CONCLUSIONSThe H(1) genotype of wild-type measles viruses should be the main epidemic strain and main pathogen that caused measles outbreaks and sporadic cases in Jilin Province.

Objective To investigate the value of nerve conduction studies (NCSs),F wave analysis,somatosensory evoked potential (SEP) and skin sympathetic response (SSR) in the early diagnosis of diabetic peripheral neuropathy (DPN).Methods A total of 110 patients with diabetes mellitus were recruited as the diabetic group and another 50 well-matched healthy volunteers as the normal controls.Sensory and motor NCSs of the median,ulnar,posterior tibial and common peroneal nerves were performed.F waves were recorded from the median and posterior tibial nerves.SEPs elicited by stimulation to nerves of both the upper and lower limbs as well as SSRs were measured,all in both the diabetic group and the normal controls.Results The total rate of nerve conduction abnormality was 74.5％ in the diabetic group,with sensory nerve conduction abnormalities more frequent and more severe among motor nerves in the extremities.The total rate of F wave abnormalities was 57.3％ in the diabetic group.The rate in patients with normal distal motor conduction in their median and posterior tibial nerves was 50.7％.The total SEP abnormality rate was 70.0％ with regard to the proximal peripheral nerve potentials in the diabetic group,but there was no obvious abnormality of the supraclavicular electrical potential in the upper limbs for those with normal sensory nerve conduction in the median nerve.The rate of occurrence of abnormality in the gluteus point potential in the lower limbs of those with normal posterior tibial sensory conduction was 62.5％.The total rate of SSR abnormalities was 80.0％ in the diabetic group but 72％ among those with normal nerve conduction in their extremities.Combining the NCS,SSR,SEP and F wave results,the total abnormality rate was 90.9％ in the diabetic group,which was much higher than with any single test used alone.Conclusion NCS is essential for diagnosing DPN.Early diagnosis of subclinical diabetic neuropathy will be significantly enhanced when nerve conduction,SSRs,SEPs and F waves are tested together.

Objective To prospectively compare MR pulmonary perfusion imaging with quantitative HRCT for the detection of mild chronic obstructive pulmonary disease (COPD) and classification of COPD.Methods Sixty-two consecutive patients with COPD and 17 healthy volunteers underwent pulmonary function test (PFT),HRCT and MR perfusion imaging on the same day.According to the Global Initiative for Chronic Obstructive Lung Disease (GOLD),all COPD patients were classified into 4 stages:stage Ⅰ (n =19),stage Ⅱ (n =17),stage Ⅲ (n =14),stage Ⅳ (n =12).The signal intensity of perfusion defects (SIPD),signal intensity of normal lung perfusion (SInormal) on 3D MR perfusion were obtained through postprocessing and the signal intensity ratio (RSI) was calculated.The total lung volume (TLV) was calculated automatically on HRCT and the total emphysema volume (TEV) was obtained by applying -950 HU thresholds.The TEV/TLV was deduced as emphysema index (EI).Several comparisons were made between the volunteers and COPD patients by one-way ANOVA and Kruskal-Wallis test.Results The RSI,SIPD,PEI,MSI,MSD values of MRI perfusion in volunteers (43.9 ± 7.2,48.2 ± 19.7,31.4,55.7,44.1) were significantly different from those in patients with COPD (18.1 ± 8.1,47.4 ± 20.0,8.6,30.2,22.7) (P ＜ 0.01).The RSI showed a significant difference between stage Ⅰ (24.4 ± 9.8) and stage Ⅲ (15.9 ± 5.3) or Ⅳ (9.2 ± 2.7) and between stage Ⅱ (19.9 ± 3.1) and stage Ⅳ (t =4.05-6.64,P ＜0.01).However,all MRI perfusion parameters between stage Ⅰ and stage Ⅱ,stage Ⅱ and stage Ⅲ,stage Ⅲ and stage Ⅳ were no differences (t =2.00-4.46,P ＞ 0.05).The median of EI in volunteers and stage Ⅰ-Ⅳ COPD patients were 1.2,3.8,8.0,13.7,18.3,and the quartile range were 3.7,7.1,9.2,10.5,7.7,respectively.The EI in volunteers showed significant differences with that of stage Ⅱ-Ⅳ COPD and the EI of stage Ⅳ was different from that of stage Ⅱ or Ⅰ (t =-7.32--1.85,P ＜ 0.01),but there was no significant difference between volunteers and stage Ⅰ COPD (t =-1.99,P ＞ 0.05).Conclusions The RSI of MRI is more sensitive than that of HRCT for assessing mild COPD.The severity of COPD could be reflected by MRI perfusion and HRCT.
