Objective To investigate clinicopathological features of abdominal wall endometriosis(AWE).Methods A retrospective study was conducted on 151 consecutive AWE patients undergoing treatment in Affiliated Obstetrics and Gynecology Hospital,Fudan University from January 2003 to December 2010.The period of following up was at range of 16 to 97 months.Results(1)The incidence of AWE was 1.96％(166/8469).All 151 AWE cases followed up had previous cesarean sections.The period between the previous cesarean section(CS)and the onset of symptoms of AWE was 24 months(3-192 months).However,the latency was not associated with the age at CS,incision site,gestational week at CS,duration of lactation,postpartum menstruation recovery,the choice of contraceptives and size of AWE(P ＞ 0.05).The duration of disease,defined to be the time interval between the onset of symptoms and surgery,was 26 months(2-168 months),which was negatively correlated with the latent period(r =-0.267,P ＜ 0.05)and was positively with size of AWE(patients with large-scar endometrioma with diameter of lesions ≥ 3 cm had longer disease duration than those with small-scar endometriomas ＜ 3 cm,r =0.326,P ＜ 0.05).(2)The rate of pre-operational ultrasonography detection was 97.4％(147/151).The lesion size detected by pre-operative ultrasonography was significantly smaller than that measured intraoperatively by palpation (20 mm versus 35 mm,P ＜ 0.05).Moreover,only 26.5％(40/151)of AWE patients were found to have deep infiltration by pre-operative ultrasonography.(3)All patients were managed by surgical treatment to completely excise lesions on the abdominal wall.Of all 34 patients(22.5％,34/151)took medicine preoperatively while 57 patients(37.7％,57/151)taking medicine post-operatively.The rate of recurrence was 3.1％(3/96)of cases with lesions ≥3 cm,which was significantly lower than 17.8％(8/45)in cases with lesion ＜ 3 cm(P ＜ 0.05).(4)After surgery,the symptoms were found to be relieved in 93.4％(141/ 151)of patients.The recurrence rate was 7.8％(11/141)while the average recurrent time was(20 ± 16)months.Conclusion Surgery is the main management on AWE.The risk factors associated with recurrence were size of lesion and postoperative medication.

0.05). Conclusion Keloid mainly contains collagens of types Ⅰand Ⅲ, which is different in arrangement and content of collagens from that in scar. Compared with immunohistochemical technique, sirus red staining and polarization microscopy is a ideal method in analysis of the collagen formation and its content in human keloid.

Objective To evaluate the short- and long-term efficacy of microwave hyperthermia combined with chemoradiotherapy in treating metastatic nasopharyngeal carcinoma to the cervical lymph nodes. Methods A total of 154 cases of stage N2-N3 nasopharyngeal carcinoma (1992 stage system) were randomized into two groups: group A (76 cases, treated with microwave hyperthermia combined with chemoradiotherapy) and group B (78 ca-ses, treated with chemoradiotherapy alone). Both groups received 1 to 2 cycles of chemotherappy with cisplatin and 5-fluorouracil and then received regular radiotherapy. The total doses of radiotherapy were 70-78 Gy/35-39 f, 47-51 d for the primary loci of nasopharynx and 68-72 Gy/34-36 f,46-50 d for the metastatic loci in the neck. Group A received microwave hyperthermia on the metastatic cervical node at the beginning of radiotherapy, with the micro-wave hyperthermia administered for 45 min every time,two times a week, totaling 8 to 14 times. Results The complete extinction rates of neck metastatic carcinoma were 80.3% and 61.5% , respectively, in groups A and B (P<0.05). The overall response rates of neck metastasis in the two groups were 100% and 96.2% , respective-ly. When the cervical lymph node metastasis disappeared, the radiotherapy doses in group A and B were (45.8 ± 5.46 ) Gy and (58.8±5.03 ) Gy, respectively (P<0.01). The 5-year local control rates of cervical lymph node in group A and B were 97.4% and 76.9%(P<0.05 ), respectively. The one-, three- and five- year survival rates were 97.4% , 76.3% and 59.2% respectively, in group A, versus 93.6% (P>0.05) ; and 52.6% (P< 0.01) and 41.0% (P<0.05), respectively, in group B. Conclusions Microwave hyperthermia combined with chemoradiotherapy can elevate the complete extinction rate of cervical lymph node metastasis of nasopharyngeal carcinoma and reduce the radiotherapy dose needed of effective control. The 5-year local control rate of cervical lymph node metastasis in combined therapy group is superior to that in the chemoradiotherapy alone group,and can elevate the long-term survival rate of patients.

Objective To investigate the effects of remffentanil pretreatment on myocardial ischemiareperfusion (I/R) injury in rabbits. Methods Thirty healthy rabbits, aged 12-18 months, weighing 2.5-3.5 kg,were randomly divided into 3 groups (n = 10 each): I/R group, low-dose remifentanil pretreatment group (group R1 ) and high-dose remifentanil pretreatment group (group R2 ). Myocardial I/R was induced by ligation of anterior descending branch of left coronary artery for 30 min followed by 6 h of reperfusion in the 3 groups. Remifentanil was infused intavenously at 1.65 and 3.30 μg· kg - 1 · min- 1 for 30 min before ischemia in group R1 and R2 respectively, while equal volume of normal saline was infused instead in group I/R. Blood samples were taken for determination of serum cardiac troponin-Ⅰ (cTnI) and creatine kinase-MB isoenzyme (CK-MB) concentrations before administration (baseline), after administration, at 30 min of ischemia and at 6 h of reperfusion. The rabbits were then sacrificed and hearts removed. Myocardial tissues were obtained for microscopic examination. Results Serum cTnI and CK-MB concentrations were significantly lower in group R1 and R2 than in group I/R and serum cTnI concentration lower in group R2 than in group R1 ( P ＜ 0.01). Remifentanil infusion significantly attenuated the pathologic changes in a dose-dependent manner. Conclusion Remifentanil pretreatment provides protective effect against myocardial I/R injury in rabbits and it is related to the dose.

Objective To construct the targeting vector for conditional gene knockout of sex hormone?binding globulin(Shbg)in mice. Methods Based on Red/ET,two LoxP were inserted into both sides of extron 4 and extron 7 for conditional gene knockout of murine Shbg. Firstly,the Shbg gene and its upstream,downstream genes obtained from BAC DNA by PCR were cloned into plasmid pBR322?MK,which was named pBR322?MK?AB. The retrieve plasmid(pBR322?Shbg?Re)was obtained by homologous recombination between the plasmid and BAC.Then a great quantity of Neo fragments obtained from PL452 and PL451 were inserted into the targeting vector after another round of Red/ET and then the final targeting vec?tor(pBR322?MK?SHBG?cko)was achieved. Results The correct structures of the targeting vectors such as pBR322?MK?AB,pBR322?Shbg?Re, SHBG?Ln and pBR322?MK?Shbg?cko were confirmed by restriction enzyme digestion and sequencing analysis. Conclusion The targeting vector for conditional knockout of murine SHBG was successfully constructed. The construction of targeting vector paved the way for conditional knockout mouse strain generated by targeted mutation of Shbg.

Objective To evaluate long-term efficacy of microwave hyperthermia combined with chemoradiotherapy for nasopharyngeal carcinoma (NPC) with cervical lymph node metastasis. Methods A total of 154 patients with stage N2 or N3 NPC ('92 staging system) were randomized into two groups:microwave hyperthermia combined with chemoradiotherapy (Group A, 76 cases) and chemoradiotherapy alone (Group B, 78 cases). Both of the two groups received 1 -2 cycles of chemotherapy of cisplatin and 5-fluorouracil, followed by conventional radiotherapy of 70 - 78 Gy in 35 - 39 fraction to the nasopharynx and 68 -72 Gy in 34 - 36 fractions to the neck. Group A received microwave hyperthermia to the metastatic cervical nodes at the beginning of radiotherapy. The hyperthermia was given as 45 min every time, twice a week for 8 - 14 times totally. Results The 5-year complete response rates of cervical lymph nodes in group A and B were 97% and 77% (x2 = 14. 24,P<0. 01). The distant metastasis rates in the two groups were 37% and 44% (x2 = 0. 73, P > 0. 05). The disease-free survival rates were 51% and 21% (x2 = 15.91, P <0. 01). The 5-year overall survival rates were 59% and 41%, respectively (x2 = 5.09, P < 0. 05).Conclusions For patients with stage N2 or N3 NPC, microwave hyperthermia combined with chemoradiotherapy can improve the complete response, disease-free survival and overall survival.

OBJECTIVETo observe the effects of acupoint catgut embedding assisting western medication and simple western medication on blood pressure and vascular endothelial function in patients with essential hypertension (EH), and to explore its mechanism.

METHODSA total of 125 cases were randomly assigned into an observation group (62 cases, 2 dropping) and a control group (63 cases, 3 dropping). Oral administration of lotensin (10 mg, once a day) was applied in the control group. Based on the treatment as the control group, acupoint catgut embedding was applied at Fengchi (GB 20), Ganshu (BL 18), Shenshu (BL 23), Quchi (LI 11), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) in the observation group, once every two weeks, and six treatments was taken as one session. All the patients were treated for 3 months. The blood pressure and the vascular endothelial injury markers, including endothelin-1 (ET-1), nitric oxide (NO), high sensitive C reactive protein (hsCRP) were recorded before and after treatment in the two groups. In addition, the ET-1, NO and hsCRP were collected from 60 cases of healthy participants.

RESULTSThe diastolic blood pressure and systolic blood pressure reduced after treatment in the two groups (all <0.05), which were more significant in the observation group (<0.01, <0.05). Before treatment, compared with those of the healthy participants, ET-1 and hsCRP were higher but NO was lower in the observation group and the control group (all <0.05); after treatment, ET-1 and hsCRP were reduced and NO increased in the two groups (all <0.05), which were more significant in the observation group (all <0.05). After treatment, the differences of NO and hsCRP between the observation group and healthy participants were not significant (both >0.05). The marked effective rate was 70.0% (42/60) in the observation group, which was superior to 33.3% (20/60) in the control group (<0.05); the total effective rate was 96.7% (58/60) in the observation group, which was superior to 85.0% (51/60) in the control group (<0.05).

CONCLUSIONThe vascular endothelial function is injured in EH patients. Based on lotensin treatment, acupoint catgut embedding could significantly improve blood pressure and vascular endothelial function.
