Activating blood and dissolving stasis is one of the important principles of clinical anti-tumor by traditional Chinese medicine and the anti-tumor effect of the blood-activating and stasis-resolving drugs has been confirmed by a large number of studies. But in recent years, some experimental studies have found that some blood-activating and stasis-resolving drugs could promote tumor metastasis. And then the clinical application of this kind of drugs has suffered from many controversial problems. Chinese materia medica (CMM) with breaking blood stasis and resolving mass (Poxue herbs) is a kind of blood-activating and stasis-resolving drugs which display the severe effect. Nowadays some researchers confirmed its obvious antineoplastic effect and its prominent anti-tumor metastasis effect, which indicated in recent studies. In this article, we summarized the anti-tumor metastasis effect and mechanism of the Poxue herbs like Curcumae Rhizoma, Sparganii Rhizoma, large blister Beetle, leech, and its effective components in detail. And we also put forward that Poxue herbs are the ones which have the anti-tumor metastasis effect among blood-activating and stasis-resolving drugs, and it valued with significant clinical application and development. It is also believed that the Poxue herbs could inhibit the tumor metastasis which is related with aerobic glycolysis and can provide the theoretical direction to guide clinical application.

OBJECTIVEThe SSR information in the transcriptome of Erigeron breviscapus was analyzed in this study, in order to further develop new functional genes SSR markers laid a solid foundation.

METHODSSR loci were searched in all of 52,060 unigenes by using est_timmer. Perl program and SSR primers were designed by Primer3. Furthermore, 36 pairs of primers were randomly selected for the polymorphism analysis on 13 Erigeron breviscapus plants collected from different places.

RESULTA total of 3639 SSRs were found in the transcriptome of Erigeron breviscapus, distributed in 3260 unigenes with the distribution frequency of 6.99%. Di-nucleotide repeat was the main type, account for as much as 34.41% of all SSRs, followed by mono-nucleotide (31.41%) and tri-nucleotide repeat motif (28.08%). The di-nucleotide repeat motifs of AT/AT and AC/GT were the predominant repeat types (28.71%). The tri-nucleotide repeat motifs of AAT/AT was the predominant repeat types (7.94%). For validation the availability of those SSR primers, we randomly selected 36 pairs of primers for PCR amplification. Among them, 34 pair primers (94.44%) produced clear and reproductive bands, 19 pair primers showed polymorphism (52.78%), and 13 Erigeron breviscapus plants were divided into 2 groups.

CONCLUSIONThere are numerous SSRs in Erigeron breviscapus transcriptome with high frequency and various types, this will provide abundant candidate molecular markers for genetic diversity study and genetic map in this plant.

With the increasing application of immune checkpoint inhibitors(ICI)in anti-tumor therapy,ICI related infections are often neglected.Mycobacterium tuberculosis(MTB)is also a common pathogen.We reported a case of ICI related pulmonary tuberculosis from Zhongshan Hospital,Fudan University.Meanwhile,18 cases of ICI related tuberculosis infection were collected through literature search,and the characteristics of ICI related tuberculosis were analyzed to improve the understanding in clinic practice.All the cases were confirmed TB including 15 cases of pulmonary tuberculosis(1 case with complication of intestinal tuberculosis)and 4 cases of extra-pulmonary tuberculosis(1 case of disseminated tuberculosis,bone tuberculosis,tuberculous pericarditis and tuberculous pleurisy,respectively).The chest CT characteristics of pulmonary tuberculosis mainly included centrilobular nodules,ground glass nodules,empty lesions,patchy shadows,consolidation and large infiltration.Eighteen cases started anti-tuberculosis treatment,while 4 cases continued ICI treatment.Three cases suspended ICI(2 cases had remission after reuse)and 11 cases stopped ICI,and 1 case was not mentioned.ICI related tuberculosis may be a direct complication of tumor immunotherapy.It is necessary to screen tuberculosis infection and exclude active tuberculosis before immunotherapy.If there are suspected symptoms such as fever,cough and sputum during ICI treatment,active tuberculosis should be taken into account.

OBJECTIVETo evaluate endoscopic ultrasonography for masses in nasal cavity and paranasal sinus.

METHODSUnder the guidance of nasal endoscope, sonographic scan of 18 masses within nasal cavity and paranasal sinus was performed by using 10 MHz catheter transducer with diameter of 3.3 mm under local anesthesia. Twelve of them were benign tumors and 6 of them were malignant ones, which were confirmed by pathological examination of resected specimens.

RESULTSUnder the guidance of nasal endoscope, masses could be observed accurately with catheter transducer. On gray scale ultrasound, most masses were heterogeneous hypoechoic, tumors with rich blood vessels were lower hypoechoic, and some showed irregular anechoic area due to dilated vascular net. Neurofibroma was with well-defined and regular border and entire capsule; chordoma was without distinct edge and capsule. A giant pituitary tumor eroding bone of sphenoid sinus and intruding into nasal cavity. The relationship between mass and internal carotid artery could be demonstrated using color Doppler flow imaging (CDFI). Blood flowing signals in masses could be detected by CDFI, and spectral Doppler could discriminate arterial or venous blood flowing signals and measure its velocity. The rich blood supply was observed in fibroangioma, the rich flow signals and high velocity could be detected in malignant tumors.

CONCLUSIONSNasal endoscope-guided sonography for soft tissue masses in nasal cavity is of exact location, clear image and high resolution, which can reveal blood flow signals sensitively, differentiate arterial and venous blood signals and measure the velocity of them. It provides a new imaging modality for masses within nasal cavity, sinuses and skull base.

OBJECTIVETo investigate the effect of early rehabilitation intervention on the incidences of extrauterine growth retardation (EUGR) and early diseases in preterm infants.

METHODSThe appropriate-for-gestational-age preterm infants with a gestational age of <34 weeks and a birth weight of 1 000 to <2 000 g who were admitted to the neonatal intensive care unit (NICU) within 24 hours after birth were enrolled in a prospective randomized controlled trial. These infants were randomly divided into rehabilitation intervention group and control group. The infants in the rehabilitation intervention group were given early rehabilitation after their vital signs became stable, including oral sensory and muscle strength training and pressure touching of the head, chest, abdomen, extremities, hands, and feet. The primary outcome measures were the time to independent oral feeding, length of hospital stay, and incidence rate of EUGR. The secondary outcome measures were the incidence rates of related diseases in preterm infants, such as apnea, feeding intolerance, and sepsis.

RESULTSA total of 97 preterm infants who met the inclusion criteria and had complete data were enrolled, with 48 in the control group and 49 in the rehabilitation intervention group. The rehabilitation intervention group had a shorter time to independent oral feeding than the control group (P<0.05). Compared with the control group, the rehabilitation intervention group had a shorter length of hospital stay and a lower corrected gestational age at discharge (P<0.05), as well as a lower incidence rate of EUGR (P<0.05). The rehabilitation intervention group ONCLUSIONS: Early rehabilitation intervention for preterm infants in the NICU may reduce the incidence rates of apnea, feeding intolerance, and EUGR and help them to achieve independent oral feeding early.

BACKGROUNDIt has been demonstrated that only 10%-20% cigarette smokers finally suffer chronic obstructive pulmonary disease (COPD). The underlying mechanism of development remains uncertain so far. Nitric oxide (NO) has been found to be closely associated with the pathogenesis of COPD, the alteration of NO synthase (NOS) expression need to be revealed. The study aimed to investigate the alterations of NOS isoforms expressions between smokers with and without COPD, which might be helpful for identifying the susceptibility of smokers developing into COPD.

METHODSPeripheral lung tissues were obtained from 10 nonsmoker control subjects, 15 non-COPD smokers, and 15 smokers with COPD. Neuronal NOS (nNOS), inducible NOS (iNOS), and endothelial NOS (eNOS) mRNA and protein levels were measured in each sample by using real-time polymerase chain reaction and Western blotting.

RESULTSINOS mRNA was significantly increased in patients with COPD compared with nonsmokers and smokers with normal lung function (P < 0.001, P = 0.001, respectively). iNOS protein was also higher in COPD patients than nonsmokers and smokers with normal lung function (P < 0.01 and P = 0.01, respectively). However, expressions of nNOS and eNOS did not differ among nonsmokers, smokers with and without COPD. Furthermore, there was a negative correlation between iNOS protein level and lung function parameters forced expiratory volume in 1 s (FEV₁) (% predicted) (r = -0.549, P = 0.001) and FEV₁/forced vital capacity (%, r = -0.535, P = 0.001).

CONCLUSIONSThe expression of iNOS significantly increased in smokers with COPD compared with that in nonsmokers or smokers without COPD. The results suggest that iNOS might be involved in the pathogenesis of COPD, and may be a potential marker to identify the smokers who have more liability to suffer COPD.

OBJECTIVETo analyze the epidemiological characteristics of hand foot and mouth disease (HFMD) in Ningbo.

METHODSA descriptive analysis was conducted through the surveillance data of HFMD in Ningbo, Zhejiang province, from 2008 to 2011. Genes on EV71 and Cox A16 were amplified with RT-PCT from the stool samples of HFMD patients. Sequences were analyzed by bioinformatics software.

RESULTS37 524 cases of HFMD were reported from 2008 to 2011, including 196 severe cases and 12 deaths. The reported incidence was 145.26 per 100 000 and the case fatality was 0.03%. Cases in children aged 5 or younger accounted for 95.89%, and the scattered cases accounted for 64.10%. Xiangshan and Ninghai counties had the highest incidence rates in Ningbo. The peak of incidence was from April to July. The number of male patients was obviously higher than females. 2394 cases of HFMD were laboratory confirmed and EV71 with the predominant epidemic strain. Data from phylogenetic analysis revealed that EV71 isolated from HFMD patients in Ningbo belonged to C4a evolution branch of C4 sub-genotype, with several transmission chains. Cox A16 belonged to B1 evolution branch. 53.48% of the healthy children in Ningbo showed EV71 antibody positive. The geometric mean of the antibody titer (GMT) was 11.23 (8.33 - 14.98) in healthy children. Cox A16 antibody was detected at 63.18% of the healthy children in Ningbo. GMT in healthy children was 12.61 (6.70 - 16.52).

CONCLUSIONHFMD was highly endemic in Ningbo, with children under 5 years old were at high-risk. The major etiologic agent was EV71 which belonged to C4a in the C4 sub-genotypes. Cox A16 belonged to the B1 evolution branch, which were in line with the predominant virus circulating in the mainland of China.

Objective To study the changes of plasma normetanephrine(NMN) and metanephrine(MN) during the resection of adrenal pheochromocytoma. Methods Fourteen patients with adrenal pheocromocytoma and 9 patients with adrenal cortex tumor were recruited in our study. Blood samples were obtained at these time points: after anesthesia induction,the beginning of incision of skin, when exploring the tumor,resection of the tumor, and the end of anesthesia. The NMN and MN were determined by high performance liquid chromatogram (HPLC). Results NMN were obviously different among 5 time points in the patients with adrenal pheocromocytoma (P0.05). No significant difference was found between NMN and MN in the patients with adrenal cortex tumor. Conclusion NMN has markedly changed during the resection of adrenal pheochromocytoma, while MN has been relatively stable. The anesthesia induction and exploring of the tumor are the key of a successful operation. MN is the stable index in the diagnosis of adrenal pheochromocytoma.

OBJECTIVETo study the potential risk factors of human infecting with Streptococcus suis.

METHODS1: M matched case-control study was conducted. 29 human cases of Streptococcus suis infection in the early phase were included in the case group, Patients' family members, neighbors and peoples who had worked together with patients to handle deceased or sick pigs in the last week were recruited as matched controls. There were 147 controls in total. Both cases and controls received questionnaire investigation including the ways to contact sick/dead pigs. Conditional logistic regression was employed to analyze matching data.

RESULTSAccording to the results of multivariate analysis, slaughtering (OR = 11.978, 95% CI: 3.355-42.756), carcasses cutting and processing (OR = 3.008, 95% CI: 1.022-8.849) sick/dead pigs were associated with cases related to human Streptococcus suis infection. The attributable risk proportion were 91.65% and 66.76% respectively. The other types of exposures to sick/ dead pigs, including feeding, selling, burying and eating, were not associated with the human Streptococcus suis infection in our study population.

CONCLUSIONSlaughtering, carcasses cutting and processing sick/dead pigs were important risky behavior for humans to be infected by Streptococcus suis.

OBJECTIVETo describe the clinical and epidemiological features of dead cases with human Streptococcus suis infections, and to find the target population for preventing death and the related indicators.

METHODSEpidemiological investigation on human Streptococcus suis infections was implemented used unified questionnaires. Analysis on dead cases and survival cases (as contrast) was done.

RESULTSThe population with highest fatality rate was in 40-49 age group. 97.37% of dead cases had toxic shock syndrome. The mean interval from onset to admission was 0.76 days, and the mean course was 2.11 days. The progression among dead cases was faster than that among survival cases. Chief clinical manifestations of dead cases that are more frequent than survival cases are purpura (73.68%), diarrhea (50.0%), dyspnea (21.05%), conjunctival congestion (34.21%), etc. Renal impairment and liver involvement in dead cases were more significant than that in survival cases. No significant difference between mean incubation period, exposure rates of main risk factors in dead cases and in survival cases was found.

CONCLUSIONPreventing toxic shock syndrome might reduce the fatality rate. The target population for preventing death is aged > or = 40. Liver function and renal function testing might be indicators for monitoring the progression of human Streptococcus suis infections.
