Objective: To observe the anemia situation and pregnancy outcome of pregnant women with iron deficiency anemia ( IDA) treated with polysaccharide iron complex. Methods:Totally 102 patients with IDA were randomly divided into the control group (51 cases) and the study group (51 cases). The control group was treated with iron dextran tablets orally, and the study group re-ceived polysaccharide iron complex. The improvement of anemia and the pregnancy outcome were compared, and the adverse reactions were recorded. Results:After the treatment, hemoglobin ( Hb) , serum iron ( SI) , serum ferritin ( SF) and serum transferrin receptor ( sTfR) at 24-week pregnancy and before the delivery, the red cell count ( RBC) and mean corpuscular hemoglobin ( MCH) before the delivery in the study group were all better than those in the control group (P<0. 05). The incidence of adverse reactions in the two groups was similar. Conclusion:Polysaccharide iron complex can improve anemia status of pregnant women with IDA, which is worthy of widely clinical use.

Objective To evaluate the clinical value of sentinel lymph nodes (SLN) in predicting pelvic lymph node status for early cervical squamous cell carcinoma,and approach the clinical significance of SLN detection for guiding radical abdominal trachelectomy (RAT).Outcomes of follow up and fertility were also observed.Methods A total of 31 patients with stage Ⅰ a2-Ⅰ bl squamous cell carcinoma planned to be given RAT and pelvic lymphadenectomy were enrolled.99mTe-labeled phytate was injected before surgery.Intraoperatively,SLN were identified,excised,and submitted to fast frozen section.Systematic bilateral pelvic lymphadenectomy was performed,and then RAT was performed in patients with negative SLN.All nodes were sent for routine pathological examination and immunostained with anti-cytokeratin antibody to detect micrometastases.Results SLN were detected in all patients (100％,31/31).A total of 109 SLN were identified with a mean number of 3.5 per patient.Of these,SLN of 2 patients were positive on frozen sections and proved to be metastasis by final pathologic examination and quitted the RAT.No missed micrometastasis was found using immunohistochemical staining in SLN and other lymph nodes using histologically node-negative cases.No false negative cases was found and the negative value was 100％ (31/31).The sensitivity,accuracy,and false negative rates were 100％,100％,and 0,respectively.Perioperative complications occured in 5 patients including 2 cases of bladder injury and 3 cases of uterine artery injury.No relapses occurred during follow-up.Five of 19 patients with procreative desire conceived pregnancies (4 spontaneous abortion and 1 premature birth) after surgery.Conclusions The identification of SLN using 99mTc-labeled phytate could predict the pelvic lymph node status in early stage cervical cancer.Under the guidance of SLN detection,RAT is a feasible operative modality with well prognosis and low complications for young patients who desire to preserve reproductive function.

Objective:The benefits of postoperative adjuvant therapy method for low-risk early-stage cervical squamous cell carcinoma were investigated. Methods:A total of 133 patients with low-risk early-stage cervical squamous cell carcinoma were treated at Shandong Cancer Hospital&Institute from February 2008 to March 2012. All patients received adjuvant therapy:42 were treated with pelvic ra-diotherapy (RT), 47 were treated with adjuvant chemotherapy (CT)+intracavitary radiotherapy (ICRT), and 44 were treated with concurrent chemoradiation (CCRT). Disease-free survival (DFS) and complications of the therapy were evaluated. Results:No significant differences in DFS were observed in the patients treated with RT, CT+ICRT, and CCRT (P>0.05), and the three-year DFS rates were 94.0%, 93.4%, and 97.6%, respectively. The frequencies of grade III to IV acute toxicities were significantly higher in patients treated with CCRT (34.1%) than in those treated with RT (9.5%) or CT+ICRT (16.7%) (P<0.05). No statistically significant difference was observed between the RT group and the CT+ICRT group (P>0.05). Grade I to II late toxicity was significantly more frequent in the CCRT (25%) and RT (19.0%) groups compared with the CT+ICRT group (4.3%) (P>0.05), but no statistically significant differences were observed between the CCRT and the RT groups (P>0.05). Conclusion:CT+ICRT or RT has a three-year DFS rate equivalent to CCRT but with fewer therapy com-plications for low-risk early-stage cervical squamous cell carcinoma.

Objective To identify and verify the different genes expression pattern between human endometrial endothelial cells (HEEC) isolated from endometrial cancer and normal endometrium.Methods Endothelial cells were isolated from 5 patients with endometrial cancer (endometrial cancer group 1) and 5 patients with normal endometria tissue (control group 1) admitted from June to November 2007 in Shandong Cancer Hospital.Global expression patterns of endothelial cells were examined using oligonucleotide microarrays.Tissues from 36 patients with endometrial cancer(endometrial cancer group 2) and 10 normal endometrial tissues (control group 2) admitted from January 2007 to April 2008 were selected to verify the expression of different genes,in which up-regulated genes including ESM1,MMP-10,SPP1 and HMGB1 were tested by quantitative real-time PCR and immunohistochemistry.Results Microarray analyses revealed 317 genes that exhibited ＞ 2-fold or ＜ 0.5 differences were identified (including 191 genes up-regulated and 126 down-regulated).Pathway analysis showed that these genes involved cell cycle,cell adhesion molecules,and extracellular matrix-receptor interaction were obviously predominant.Of them,97 up-regulated genes and 44 down-regulated genes were related to angiogenesis.The mRNA expression of ESM1,MMP-10,SPP1 and HMGB1 in endometrial cancer group 2 were 0.898、3.890、1.433 and 1.881,respectively.Positive expression of SPP1,MMP-10,ESM1 and HMGB1 was observed in endometrial cancer group 2.However,the SPP1,ESM1 and HMGB1 was negative expressed in control group 2.Conclusion It shows that there are the different angiogenesis related genes between endometrial cancer and normal endothelium,which will provide insights into the anti-angiogenesis therapy for endometrial cancers.

Objective To observe and cpmpare the efficacy and complications of hyperfractional integrated intraeavitary brachtherapy in middle-advanced squamous-cell carcinoma with the traditionsl brachytherapy.Methods In the observed group,328 patients with cervical cancer received hypeffractional integrated intracavitary after loading therapy between Jan 2004 and Jan 2005 were selected.The dose of point A was 2.5 Gy-3.0 Gy/fraction,2 fractions per week,and the total dose of reference point A was 49.8 Gy in stage Ⅱ b,52.6 Gy in stage in Ⅲb.In the control group,331 cases treated with traditional aflerloading brachytherapy between Jan 2002 and Dec 2003 were selected.The dose of point A was 5.0～7.0 Gy/fraction,1 fraction per week,and the total dose of point A was 50.1 Gy in stage Ⅱb,53.5 Gy in stage Ⅲb.In vitro irradiation began at the same time with the intracavitary brachytherapy.The whole pelvic was irradiated with 15 MV X-rays.Results In the observed group,the recent control rate of stage Ⅱb was 97.2%(104/107),94.1%(208/221)for stage Ⅲb.The 3-year survival rate was 80.5%(264/328).and the 5-year survival rate was 68.6%(225/328).The complication rate was 5.2%(17/328)for cystitis, 14.6%(48/328) for proctitis.Out of 331 cases in control group,the recent control rate of stage Ⅱb was 95.4%(103/108),92.8%(207/223)for stage Ⅲb.The 3-year survival rate was 75.2%(249/331),the 5-vear survival rate was 62.5%(207/331).The complication rate was 13.3%(44/331)for cystitis,and 32.3%(107/331)for proctitis.Conclusions Compared with combination of traditional brachytherapy and external radiotherapy,combination of hyperfraetional integrated brachtherapy therapy and external radiotherapy has no significant improvement for recent control rate and long-term survival rate,but could reduce the complication rates of cystitis and proctitis.

Objective To simulate the biomechanical characteristics of pelvic-ligament-muscle during vaginal delivery and rest, and to explore the injury of levator ani muscles during vaginal delivery, pelvic organ prolapse and stress urinary incontinence. Methods The three-dimensional (3D) nonlinear finite element model of pelvis-ligament-muscle was established to calculate the stress and strain distributions and injury of levator ani muscles under different abdominal pressures and loads. The stress and strain distributions as well as damage of type I, Ⅱ, Ⅲ stress urinary incontinence and pelvic organ prolapse were also calculated. Results The highest equivalent stresses of levator ani were 14, 29, 43, 86, 144, 230 kPa, respectively, when the abdominal pressure was 1 kPa under the load of 3, 5, 8 kPa and the abdominal pressure was 1.5 kPa under the load of 3, 5, 8 kPa. The stresses of type I, Ⅱ, Ⅲ stress urinary incontinence and pelvic organ prolapse were 1.69, 1.01, 0.70, 1.58 MPa. Conclusions Vaginal delivery would result in the damage to the puborectalis and the middle of the pubococcipital muscle, which was consistent with the damage of the anal levator muscle with pelvic floor dysfunction. This study uses scientific method to find out the exact location of pelvic floor injury during vaginal delivery, which can provide references for clinicians to prevent pelvic floor disease and formulate post natal rehabilitation training.

Objective:To evaluate the effect of clinical pathway implementation on medical efficiency and medical expenses of patients with two common rheumatic immune diseases " rheumatoid arthritis" and " ankylosing spondylitis" diseases by using diagnosis related group (DRG) related indicators.Methods:The data of patients with two common rheumatic immune diseases " rheumatoid arthritis" and " ankylosing spondylitis" included in the clinical pathway management from January 2017 to December 2019 in the Department of Rheumatology and Immunology of Jinhua Hospital, Zhejiang University School of Medicine were carried out. The impact of clinical pathway implementation on the average hospital stay, average cost and average drug cost of patients with the two diseases were analyzed and compared , so as to evaluate the effect of the implementation of the clinical pathway.Results:From the implementation of clinical pathway in 2017 to 2019, the number of patients admitted and total medical specialty services in the two groups of " rheumatoid arthritis" and " ankylosing spondylitis" increased year by year ( P<0.01). The average length of stay, average cost and average drug cost of patients in the " rheumatoid arthritis" disease group decreased year by year, with statistically significant differences between groups (all P<0.01). The average length of stay in the ankylosing spondylitis group was shortened year by year, and the difference was statistically significant ( P<0.01). Compared with 2017, the average cost in 2018 decreased significantly, and the difference was statistically significant ( P<0.01). There was no significant difference in average cost between 2018 and 2019 ( P>0.05). The average cost in 2018 was significantly higher than that in 2017 ( P<0.05). After analyzing the causes and optimizing the clinical pathway, the average cost in 2019 was significantly lower than that in 2018 ( P<0.01). Conclusions:Through the implementation of clinical pathways and continuous optimization of pathway connotation during use, the diagnosis and treatment efficiency of patients with " rheumatoid arthritis" and " ankylosing spondylitis" can be significantly improved, and medical costs can be reduced, which is in line with the current medical reform needs.

Objective:To establish an animal model of trans-sutural distraction osteogenesis in SD rats.Methods:A self-designed V-shaped distraction device(distractor)was fabricated with the traction force(N)of 0,1.3,2.2,3.0,4.3 and 5.0 corresponding to the distraction length(mm)of 5,4,3,2,1 and 0 respectively,meeting the trans-sutural distraction osteogenesis requirements in skull of 5-week-old SD rats.The distractor was plased into the sagittal suture of 12 SD rats.Continuous sampling was conducted 1,3,5 and 7 days respectively(n=3)after operation.The tissue changes in the trans-sutural distraction area were observed by HE and Masson's trichrome staining.Inflammation levels were determined using Arg-1 immunofluorescence staining.The early angiogenesis was clarified through co-staining with CD31 and EMCN.Results:A stable trans-sutural distraction osteogenesis model was estab-lished,5 mm distraction osteogenesis width was observed completely within 7 days of distraction.Significant new bone formation was observed at 7 days after operation.Arg-1 expression increased and was concentrated at the bone margins,overlapping with the areas of new bone formation.EMCN expression gradually decreased,and by day 7 CD31 was predominant,indicating the basic maturation of blood vessels.Conclusion:This study successfully constructed a stable and effective trans-sutural distraction osteogenesis animal model,and provides an experimental basis for the investigation of its early continuous histological changes.

Remote pharmaceutical care refers to the process that pharmacists provide pharmaceutical care to patients remotely through information technology. Remote pharmaceutical care in China starts late and develops slowly. Therefore ，this paper discusses the pharmaceutical care modes that pharmacists at home and abroad can provide under the remote mode by collecting literature. The results show that foreign remote pharmaceutical care starts early and is relatively mature. The service mainly included remote follow-up and intervention ，24-hour online prescription and order review ，24-hour online drug reorganization ，and guidance on rational drug use in remote areas or community hospitals. The service population covers patients with cardiovascular disease ， diabetes，asthma，AIDS and so on. Some hospitals have established an integrated pharmaceutical care system of “Internet+Medical Consortium”in China ，with which pharmacists can provide patients with pharmaceutical care such as remote follow-up and intervention，drug consultation and so on. With the promotion of telemedicine ，domestic pharmacists can gradually expand the scope of services ，expand pharmaceutical services such as remote consultation and remote popular science push ，and realize the sharing of high-quality pharmaceutical care for the whole people.
