Objective To analyze clinical features and sum up experience for the treatment of ischemic bowel disease. Methods Clinical data of 73 patients with the diagnosis of ischemic bowel disease were retrospectively analyzed. ResultsTwenty-eight patients were male and 45 patients were female. The median of age was 65 years (range of 38 to 89 years). Forty-eight patients were associated with hypertension, 23%(17/73) patients had a history of coronary disease and 15% (11/73) had diabetes. Seventy patients presented symptom of abdominal pain and 93% (68/73) had hematochezia. Symptoms relieved by conservative treatment in 96% (63/66) patients. Nine patients underwent a surgery. One patient died of sepsis postoperatively. One suffered from colostomy necrosis and leakage of the rectum segment. Conclusion 1. Elder patients presenting symptoms of abdominal pain and hematochezia, especially with a history of cardio-cerebrovascular disease and diabetes should be considered for the possibility of ischemic bowel disease. 2. Most patients with ischemic bowel disease could be successfully treated by conservative therapy. 3. Surgery for patients with chronic relapsing and nonresponsible symptoms was difficult and patients often suffer from high postoperative complications.

Objective To investigate the changes of early and delayed washout rates of 99Tcm-methoxyisobutylisonitrile (MIBI) in ischemic heart disease (IHD), and to explore the value of 99Tcm-MIBI SPECT in evaluating impairment of ischemic myocardial cells. Methods Patients diagnosed of IHD with three-vessel stenosis ( ≥50% ) without myocardial infarction based on angiography (CAG) underwent 99Tcm-MIBI static planar and gated SPECT imaging. The early (90 min after the intravenous injection) and delayed (4 h after the intravenous injection) washout rates of 99Tcm-MIBI and left ventricular ejection fraction (LVEF) of IHD patients and normal subjects were compared using t-test. Linear correlation analysis was performed between the early, delayed washout rates and LVEF measured by gated SPECT. Results Statistically significant lower early washout rate of 99Tcm-MIBI was observed in IHD group than control group: (13.44 ± 2.87 )%vs ( 17.32 ± 4.92) %, t = 2.384, P < 0.05, but higher delayed washout rate of 99Tcm-MIBI was observed in IHD group than control group: (19.24 ±4.71)% vs (15.23 ±3.81)%, t= -2.246, P<0.05. LVEF in IHD group was significantly lower than that in control group: (55.71 ±7.97)% vs (67.75 ±5.43)%, t =-4.418, P <0.01. There were no correlations between the early/delayed washout rates and LVEF, respectively in IHD patients (r = -0.212, P > 0.05; r =0.352, P > 0.05, respectively). Conclusion 99Tcm-MIBI washout rate may reflect myocardial cell impairment due to IHD.

To evaluate the adjuvant effect of recombinant enterovirus 71 (EV71) subunit vaccine formulated with chitosan, rabbits were orally immunized with recombinant VP1 (rVP1) or rVP1 mixed with chitosan adjuvant. Levels of virus-specific IgG and IgA antibodies in sera, mucosal wash buffer (intestine, nasal cavity, and lung), and feces were determined by indirect enzyme-linked immunosorbent assay (ELISA). The titers of neutralizing antibodies against EV71 were determined using cytopathic effect-based neutralizing assay, and levels of cytokines (IFN-gamma and IL-4) secreted from in vitro-cultured rabbit splenic lymphocytes under antigen stimulation were also determined by ELISA. Results showed that immunization with rVP1 alone could only induce low levels of serum IgG and mucosal IgA, while rVP1 combined with chitosan adjuvant were able to induce significantly higher levels of antibodies, rVP1 can only induce neutralizing antibodies when used in combination with chitosan. Levels of IFN-gamma and IL-4 in the group immunized with rVP1 plus chitosan were significantly higher than those in the group immunized with rVP1 only or those in the control groups. Our study lays the foundation for development of oral VP1 vaccine against EV71 infection.

OBJECTIVESTo compare the influence of hepatitis E virus (HEV) infection on the replication of hepatitis B virus (HBV) by observing clinical features, the relationship between the number of HBV DNA copies in serum, the degree of hepatic function impairments and prognosis of chronic hepatitis B patients with hepatitis E superinfection.
METHODSOne hundred and fifteen chronic hepatitis B (CHB) patients and 115 CHB patients with hepatitis E (HE) superinfection were studied and compared. 74 liver tissue biopsy samples of the CHB and 51 of the CHB-HE sufferers were obtained. HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc, anti-HBc-IgG, anti-HBc-IgM, HBV DNA and anti-HEVIgM were detected respectively by enzyme linked immunosorbent assay and polymerase chain reaction.
RESULTSThe number of HBV DNA copies in sera in the CHB-HE group and the severity of the clinical features were significantly higher than those in the CHB group. The former group had a poorer prognosis with a 49.6% occurrence rate of severe hepatitis and a 25.2% death rate while in the latter group the corresponding rates were just 4.4% and 1.7%.
CONCLUSIONRe-infection with HEV, in those CHB patients, severely damaged their hepatic functions and increased their mortality; the older the patient and the higher the level of HBV DNA, the poorer the prognosis.

Objective: This is a review of our cases and published literature on cheiro-oral syndrome (COS), to
better understand its localization, etiology and outcome. Methods: In addition to our database, we
reviewed the medical database (including PUBMED, BIOSIS, EMBASE, and SCOPUS) and other
sources, searched by the keyword of “cheiro-oral”. The defi nition of COS was a subjective or an
objective sensory disturbance confi ned to the perioral area and the fi nger(s)/hand without a detectable
abnormality in mental, motor or cerebellar function. Only cases of COS where the clinicoanatomic
correlation could be identifi ed by neuroimaging study, autopsy or stereotatic surgery was included.
Results: There were a total of 174 patients; 85 patients from our database, 76 patients from medical
database, and 13 patients from other sources. They were 111 men and 63 women. Their age ranged
from 12 to 85 years; average being 58.2 years. Stroke is the leading etiology and constituted 74% of
the patients. The most common location of lesion was thalamus, followed by pons and cortex. Classical
unilateral COS was seen in 81% of patients, atypical COS in 19%. Whereas the lesions were from
cortex to cervical spinal cord in unilateral COS, atypical COS was associated with lesions in pons or
medulla oblongata. An early deterioration was seen in 16.5% of patients, especially in large cortical
infarction and subdural hemorrhage. Structural lesions were found in 85% of patients.
Conclusion: Classical unilateral COS do not have a high localizing value, the atypical COS is associated
with lesion in pons or medulla.

Objective:
To evaluate the impact of coronavirus disease 2019 ( COVID-19 ) prevention and control measures in Huzhou on influenza epidemic strength and characteristics in 2020, so as to provide reference for formulating influenza prevention measures.
Methods:
Using the influenza surveillance data of the national influenza sentinel surveillance system from January 2015 to July 2020, the seasonal characteristics of influenza epidemic were analyzed, the proportion of influenza-like illness cases ( ILI% ) and the positive rate of influenza virus in January to July of 2020 were compared with those of the same period in 2015-2019, in order to evaluate the impact of COVID-19 prevention and control measures.
Results :
The ILI% and the positive rate of influenza virus in Huzhou were 3.90% and 15.32% during 2015-2019, while were 4.41% and 12.63% from January to July of 2020. The trends of ILI% during 2015-2019 fluctuated similar, but continued to drop since January 2020. The positive rate of influenza virus peaked from December to March in 2015-2019, also peaked from December 2019 to January 2020, but decreased to 0 in March. ILI% was positively correlated with the positive rate of influenza virus ( r=0.682, P<0.05). The growth rates of ILI% from January to July 2020 were 4.75%, -11.27%, 0.68%, 19.84% and 0.92%, compared with the same period of 2015-2019, respectively. The growth rates of ILI% in January 2020 were much higher ( >57.00% ) and from April to July were much lower ( <-33.00% ) . The growth rates of influenza virus positive rate from January to July 2020 were -47.96%, -36.53%, -3.44%, -35.92% and -39.37%, compared to the same period of 2015-2019, respectively. The growth rates of influenza virus positive rate in January 2020 were much higher ( >11.00% ) and from February to March were much lower ( <-61.00% ).
Conclusion
Since COVID-19 prevention and control measures were implemented in January 2020 in Huzhou, the ILI% and the positive rate of influenza virus in sentinel hospitals decreased significantly.

METHODSFrom May 2009 to April 2010, 60 patients with elbow fractures treated by operation were randomly divided into two groups: combined therapy group and past procedure group. Thirty patients in the combined therapy group,including 12 males and 18 females, ranging in age from 23 to 63 years, averaged (43.53 +/- 7.74) years old; 15 patients had two parts fractures, including humeral intercondylar fractures combined with olecroanon and (or) ulna coronoid process fractures in 8 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 3 cases, fractures of olecroanon and ulna coronoid process in 3 cases, fractures of olecroanon and capitulum radius in 1 case; other 15 patients had one part fractures, including fractures of exterior or interior humeral condyle in 8 cases,fractures of olecroanon or ulna coronoid process in 6 cases, fractures of capitulum radius in 1 patient. Thirty patients in the past procedure group,including 11 males and 19 females, ranging in age from 24 to 67 years, averaged (46.13 +/- 6.22) years; 15 patients had two parts fractures, including fractures of humeral intercondylar fracture combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 2 cases,fractures of olecroanon and ulna coronoid process in 5 cases,fractures of humeral intercondylar fracture combined with capitulum radius in 1 patient; 15 pa- tients had one part fracture, including fractures of exterior or interior humeral condyle in 6 cases, fractures of olecroanon or ulna coronoid process in 8 cases, fractures of capitulum radius in 1 patient; the patients in the past procedure group were treated with past procedure methods. Mayo Elbow Performance Score (including gmotion of elbow joint) and security (using X-ray to recheck displacement fracture, internal fixation failure and heterotopic ossification) were evaluated at postoperative 6 months. From 2002 to 2006, 30 patients were reviewed as historical control group, including 17 males and 13 females, ranging in age from 27 to 62 years, averaged (47.17 +/- 7.83) years; 15 patients had two parts fractures, including fractures of humeral intercondylar combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 1 case, fractures of olecroanon and ulna coronoid process in 6 cases, fractures of ulna coronoid process and capitulum radius in 1 case; 15 patients had one part fractures,including fractures of exterior or interior humeral condyle in 9 cases, fractures of olecroanon or ulna coronoid process in 5 cases,fractures of capitulum radius in 1 case. The Mayo Elbow Performance Score of the patients in historical control group was evaluated retrospectively at postoperative 6 months and the results were compared with that of past procedure group.
RESULTSMayo score of combined therapy group was (91.00 +/- 7.81)surpassed to (76.83 +/- 10.71) of the past procedure group and (73.17 +/- 1.99) of historical control group (F = 24.98, P < 0.05). The range of motion of elbow was (102.40 +/- 9.16) degrees of combined therapy group surpassed to (83.57 +/- 6.21) degrees of the past procedure group (t = 9.325, P < 0.05). There were no internal fixation loose,obvious fracture displacement and heterotopic ossification in each X-ray examination of patients in the combined therapy group. The Mayo score of historical control group was (73.17 +/- 11.99), showing no significant differences when compared with (76.83 +/- 10.71) of the past procedure group (LSD, P = 0.172).
CONCLUSIONCombined therapy including different stage, different method combination and different subject to practice to prevent postsurgery stiffness after elbow fracture is effect, security and necessity.
