Objective:To compare the curative effect of uterine body oxytocin injection and motherwort with oxytocin on preventing the cesarean and postpartum hemorrhage and promoting the involution of uterus.Methods:160 cases of cesarean inpatients were randomly divided into the experimental and controlled groups respectively.All the cesarean patients accepted their lower uterine segment transverse caesarean section within the fascia.The controlled group got the uterine body injection of 10 units of oxytocin after the fetus was delivered,and then got another 10 units of intramuscular oxytocin injection,every 12 hours at a time,totally 6 times.The experimental group got their extra uterine body injection of 20mg motherwort,and then got another 20mg of intra-muscular motherwort injection,every 12 hours at a time,totally 6 times.The volume and case of puerperal and postpartum hemorrhage and involution of uterus were observed.Results:The comparison showed that the volume and cases of puerperal and post-natal 2-hour and post-natal 24-hour hemorrhage of the experiment group were significandy fewer than those of the controlled group,(P

Objective To explore the value of serum CA125 in prediction of the first-trimester threatened abortion.Methods The serum CA125 level of 78 patients with threatened abortionand( miscarriage success group and failure group) and 40 normal early pregnant women before treatment and after 1 ～ 4 weeks were tested by chemiluminescent immunoassay(CLIA) methods and the results were compared.Results The serum CA125 level of the failure group was significantly higher than that of the miscarriage success group[ (28.52 ± 19.12) x 103 U/L] and normal early pregnant women group [ (20.45 ± 9.55) × 103 U/L] ( t =- 1.28,- 1.24,all P ＜ 0.05 ),and it increased by degree and by time,and the sensitivity and specificity of detection was 93.1％ and 87.85％ respectively.Conclusion Monitoring of serum CA125 had highly clinical value in predicting the prognosis of threatened abortion.

Objective To study the effects of cultivation methods on growth dynamics in the aerial part and root of Angelica sinensis and Ditylenchus destructor, rate of early bolting, and yield of A. sinensis as well. Methods Compared with conventional planting, ridge planting, furrow planting, white plastic mulch coverage, and black plastic mulch coverage were used to evaluate the effects of cultivation methods on dry matter accumulating and growth dynamics of A. sinensis. Results The influence of black plastic mulch coverage to growth dynamics of A. sinensis is the biggest, next for white plastic mulch coverage. There is the best inhibition to D. destructor under ridge planting. Black plastic mulch coverage can enhance the rate of early bolting. The treatment of black plastic mulch coverage has the highest yield, which can increase the yield by 33.4% (4 650 kg/hm2) compared to conventional planting; next for the treatment of white plastic mulch coverage, which increased the yield by 24.3% (3 372.2 kg/hm2) compared to conventional planting. But there were no significant effects of ridge planting and furrow planting on increasing yield. Conclusion The cultivation methods of black plastic mulch coverage should be brought into wide use in A. sinensis cultivation.

Objective To explore the influence of pelvis obliquity in lateral position to acetabular component orientation during total hip arthroplasty (THA),and the method to correct.Methods Fifty patients (62 hips) were performed THA with posterolateral incision in lateral position by the same team.The patients were randomized and divided into experimental group (EX,with 25 cases,34 hips) and control group (CON,with 25 cases,28 hips).In EX group,the acetabular components were placed by means of the gradienter and plumb correcting technique during THA.While in CON group,the acetabular components were placed by traditional method during THA.The acetabular abduction angles were measured postoperatively,and compared between the two groups.Results The average obliquity of pelvis was-1.647°±4.512°in EX group when putting the patient in lateral position before correcting.Through the application of gradienter and plumb,the average abduction angle of acetabular component was 42.685°±3.355° postoperatively,with the difference of 1.962°±1.515° compared with the preoperative angles.And in CON group,the average abduction angle of acetabular component was 44.534°±4.844° postoperatively,with the difference of 4.244°±3.042°.The difference of abduction angle in CON group was much higher than that in EX group (P＜0.05).Conclusion The pelvic obliquity when putting the patient under lateral position will affect the surgeons'judgments of placing acetabular component during THA,furthermore,lead to inconsistency among the abduction angles obtained preoperatively,intraoperatively and postoperatively.By applying the correcting method with gradienter and plumb,the discrepancy can reduce obviously between the abduction angle measured postoperatively and that of measured during operation comparing with traditional method.

Objective To investigate the effects of transient plateau factor on acute lung injury induced by phosgene poisoning in rabbits.Methods Forty New Zealand white rabbits of both sexes,aged 2.0-2.5 kg,were randomly divided into 4 groups (n =10 each) using a random number table:control group (group C),plateau factor group (group H),phosgene poisoning group (group P),and phosgene poisoning and plateau factor group (group HP).In group H,the rabbits were exposed to a simulated altitude of 33000 m for 2 h.In group P,the rabbits were exposed to phosgene for 3 min only.In group HP,the rabbits were exposed to phosgene for 33 min and then to a simulated altitude of 3000 m for 2 h.Respiratory rate (RR) was recorded and blood samples were taken before exposure to phosgene (T1),after exposure to phosgene (T2),and at 0,1 and 6 h after onset of exposure to a simulated altitude of 33000 m (T3-5) for determination of PaO2 and oxygenation index (OI) was calculated.The chests were opened at T5 and lungs removed for determination of lung water content (LC) and for microscopic examination.Lung coefficient (LC) was calculated.Results Compared with C group,RR was significantly increased at T3 in group H (P ＜ 0.05),and RR was increased and OI was decreased at T2-5 in P and HP groups (P ＜ 0.05 or 0.01).Compared with P group,RR was increased and OI was decreased at T3-5 in HP group (P ＜ 0.05 or 0.01).LW and LC were significantly higher in P and HP groups than in group C,and in HP group than in group P (P ＜ 0.05 or 0.01).The microscopic examination showed that pathological changes were observed in P and HP groups,however,the changes were severer in HP group.Conclusion Transient plateau factor can obviously aggravate the degree of acute lung injury induced by phosgene poisoning in rabbits.

Mucinous tubular and spindle cell carcinoma of the kidney is a rare subtype of renal carcinoma. In July 2019, one case of mucinous tubular and spindle cell carcinoma of the kidney was admitted to our hospital, The laparoscopic partial nephrectomy was performed, and there was no recurrence or metastasis during the follow-up period of 13 months.

Surgical treatment is the main treatment for this disease, and most patients have a good prognosis.Howerer, the possibility of progression remains in the late stage of the disease.

肿瘤浸润性免疫细胞（TIC）参与构成肿瘤免疫微环境，调控肿瘤的生长，并影响患者的生存及抗肿瘤治疗的疗效。 TIC分布模式的类型主要有冷肿瘤型、混合型和间质型。这3种分布类型在免疫细胞的种类、数量与比例和分布位置上呈现明显 的差别。在不同肿瘤、不同个体，甚至同一肿瘤的不同区域之间，TIC分布模式既有差异性也有规律性，既有模式相似但功能相异 的差异性，也有模式不同但功能相近的规律性。TIC分布模式的分型体现的就是其差异性。近来研究发现，利用TIC分布模式可 以预测患者的预后及抗肿瘤治疗的疗效，这体现的就是TIC分布模式的规律性。本文就该领域的研究进展进行综述。

[Abstract] Objective: To detect the expression of CD39 in head and neck squamous cell carcinoma (HNSCC) tisseus, and to analyze its correlation with patients’clinicopathological features and its prognostic significance. Methods: Tissue specimens and case data of 85 patients with HNSCC underwent surgery at Cancer Hospital of Tianjin from May 2012 to December 2013 were collected for this study. Gene chips were obtained from Oncomine database, and HNSCC cell lines SCC15, UM1, and Cal25 were selected for this study. Online analysis was performed to compare the differential expression of CD39 in buccal mucosa (BM) tissues and HNSCC tissues, Western blotting and Immunohistochemistry (IHC) were used to detect the protein expression of CD39 in HNSCC tissues. Spearman’ s correlation analysis was used to study the correlation between the expressions of CD39 and clinicopathological features of HNSCC patients. Both Kaplan-Meier curve analysis and Log rank test were used to analyze the association between the expression of CD39 in HNSCC tissues and the survival of patients, and Cox risk proportional regression model was used to evaluate the relationship between CD39 expression and the risk of relapse. Results: The transcription level of CD39 was obviously up-regulated in HNSCC tissues than in BM tissues (P<0.01), and CD39 expression was detected in HNSCC cell lines SCC15, UM1 and Cal25. Dexamethasone (DXM) could enhance the expression of CD39 in UM1 cells in dose-dependent manner. CD39 was highly expressed in 53 (62.4%) HNSCC patients, which was positively correlated with preoperative chemotherapy (r=0.234, P<0.05). The recurrence-free survival (RFS) of patients with high CD39 expression was significantly shortened (P<0.05), and high CD39 expression was an independent relapse risk factor (HR=2.328, 95%CI=1.091-4.967; P<0.05) for patients with HNSCC. Conclusion: CD39 is DXM-inducively and constitutively expressed in HNSCC. And over-expression of CD39 is an independent predictor of poor prognosis in HNSCC patients, indicating its important role in the progression of HNSCC.
