Objective To investigate the epidemiological characteristics of imported malaria in Hailing District ,Taizhou City,so as to provide the evidence for formulating the effective prevention and control strategy. Methods The network reports, questionnaires and epidemic reports of imported malaria cases in Hailing District from 2010 to 2015 were collected and analyzed retrospectively. Results From 2010 to 2015,totally 46 cases of imported malaria were reported,including 40 cases of falci?parum malaria(86.96%),4 cases of ovale malaria(8.70%),1 case of quartan malaria(2.17%)and 1 case of multi?infection of falciparum malaria and tertian malaria(2.17%). No seasonal trend of time of the disease onset was observed. All the patients were return abroad with clear residence histories in malaria epidemic areas. The average time from disease onset to definite diag?nosis was 2 d and 8 patients were definitely diagnosed within 24 h. All the 46 patients were cured. Conclusion All the malaria cases reported were imported cases in Hailing District in the last five years. Effective prevention and control measures are the key to the malaria elimination.

Objective To understand the current status of Oncomelania hupensis snails and the change rules,so as to pro?vide the evidence for formulating the snail control strategy. Methods The data of snails were collected and the factors influenc?ing the changes of snail status were investigated,and all the data were analyzed in Hailing District from 2007 to 2014. Results There were 18 environments with snails in 17 villages of 3 townships in Hailing District from 2007 to 2014. The snail area was 7.832 4 hm2. Among these environments and snail areas, 6 environments and 2.134 5 hm2, snail area were detected by the village snail investigation groups, and 12 environments and 5.697 9 hm2 snail area were detected by the township snail investigation groups. In addition, in 5 non?endemic villages, 3.126 3 hm2 snail area was found. In 2008, 2012 and 2013, a total of 2.274 0 hm2 snail area was found again. Conclusions In recent years,the snail situation rises again after schistosomiasis transmission has been interrupted. Therefore,this situation should be paid attention to.

Sepsis is the systemic inlfammatory response to infection and a major cause of mortality in critical patients. The severe disorder of immune system is the common pathophysiological changes in septic patients. Mesenchymal stem cells (MSCs) have shown great immunoloregulation properties in recent studies. It can increase the level of IL-10, an anti-inflammatory cytokine, promote the secretion of prostaglandin E2 (PGE2), indolamine 2,3-dioxygenase (IDO), and regulate the proliferation, differentiation and function of the immune cells such as mononuclear macrophage, t-lymphocytes, natural killer cells and so on. MSCs may provide new ideas for the treatment of sepsis.

Objective To evaluate the therapeutic effect of total mesorectal excision in radical operation of rectal carcinoma.Methods From 1997 to 2007,126 consecutive patients with middle and inferior rectal carcinoma underwent surgical operation according to the principle of total mesorectal excision.Results Two patients(1.6%) died of postoperative pulmonary infection,and postoperative anastomotic leakage occurred in 2 cases(1.6%).The postoperative follow-up of 1-5 years showed that local recurrence rate 2 years after surgical operation was 4%(5/126),the 3-,5-year survival rate was 93.6%(116/124) and 84.7%(105/124),respectively.Conclusions Total mesorectal excision can decrease the frequency of postoperative local recurrence of rectal cancer without increasing complications as long as its correct indications are selected.

Background The pre-chop technique can decrease the use of ultrasound power,and thus reducing the loss of corneal endothelial cells (CECs) and injuries of other intraocular structures.Many currently developed manual pre-chop techniques restrict the wide application of the pre-chop technique because of their intrinsic disadvantages.The present study describes a manual pre-chop technique for pre-slicing the lens nucleus by using a novel reverse chopper,which has not been reported yet.Objective This study was to compare the efficacy and safety of pre-chop technique using a reverse chopper and stop-and-chop phacoemulsification technique on Ⅳ degree hard nucleus cataract.Methods A prospective clinical-controlled interventional study was performed.Thirty-two eyes of 32 cataract patients with Ⅳ degree of nucles were enrolled in People's Hospital of Hetian District from March 2015 to January 2016.The patients were randomized into the prechop group and matched stop-and-chop group according to random number table.The self-made reverse chopper-assisted pre-chop phacoemulsification surgery and stop-and-chop phaco surgery were performed on the eyes of corresponding groups,respectively.The ultrasound power,effective phaco duration,corneal endothelium loss rate,the eye number of different grade of cornea edema after operation and vision outcome were compared between the two groups.Written informed consent was obtained prior to relevant examination and surgery.Results The mean effective Phaco durations were 42.56 (39.31,45.81) seconds and 78.63 (73.85,83.40) seconds in the prechop group and stop-and-chop group,with a significant difference between them (Z =-4.937,P =0.000).The eye number with different degree of best corrected visual acuity (BCVA) was significantly different between the two groups,at postoperative day 1 and day 3 (P =0.013,0.033).The number of corneal endothelial cells (CECs) 1 month after surgery was (2 026.05 ± 154.03)/mm2 in the prechop group,and the number was (1 866.50-± 117.16)/mm2 in the stop-and-chop group,with a significant difference between them (t =3.298,P=0.003).The CECs loss rate was (13.36±2.85) ％ in the prechop group,which was lower than (25.77±3.81) ％ in the stop-and-chop group (t=-6.996,P=0.000).The eye number with different degree of corneal edema was significantly decreased in the prechop group compared with the stop-and-chop group at postoperative day 1 and day 3 (P =0.001,0.002).Conclusions Compared with the stop-and-chop phaco technique,a reverse chopper-assisted pre-chopping technique can decrease the intraoperative complication,lighten the postoperative damage of CECs and accelerate visual rehabilitation in hard nucleus cataract eyes.

Objective To study the effect of chitosan on the growth of the in vitro cultured retinal nerve cells. Methods The retinal nerve cells of SD baby rats were cultured in vitro. The effects of chitosan at 0.065%,1.25%,2.5%,5%,10%,15% on the growth of the retinal nerve cells were measured by MTT method. The blank control group was created. Results 1.25%,2.5%,5%,and 10% chitosan could obviously promote the growth of retinal nerve cells,and 10% chitosan was the optimal concentration for the growth of nerve cells. Conclusion Chitosan can effectively promote the growth of retinal nerve cells,and it is necessary to undertake the further study of Chitosan.

Objective To explore the clinical and pathological characteristics of ovarian endometriosis and malignant cases, and to improve our recognition of this disease. Methods A total of 1 289 cases of ovarian endometriosis were divided into two groups: the benign group (1 275 cases)and the malignant group (14 cases). They were analyzed on: dysmenorrhea, infertility, features of ultrasound examination,site of tumour,pathological types and complications. Results Malignancy arising from ovarian endometriosis was 1.09%. As far as degree of dysmenorrhea, size of cyst >10 cm, CA125 >500 U/L, features of ultrasound were concerned, difference between the two groups was statistically significant. Conclusions In the present study, the malignant rate of ovarian endometriosis was about 1%. Malignancy should be considered seriously when the following situations occured: change in the degree of dysmenorrhea, size of cyst larger than 10 cm, CA125 higher than 500 U/L, mamilla observed by ultrasound examination.
