Objective To analyze clinical characteristics and treatment experience for late complications after hysteroscopic transcervical resection of endometrium ( TCRE) . Methods Clinical data of 13 cases of late complications after hysteroscopic TCRE for dysfunctional uterine bleeding from January 2006 to June 2014 were retrospectively analyzed .A re-operation of hysteroscopic exploration and resection were required . Results The re-operation in the 13 patients found 6 cases of hematocele in uterine cavity (4 cases in the uterine horn, 2 cases in the uterine cavity) and 7 cases of focal or whole uterine endometrial hyperplasia (including 1 cases of PASS syndrome and 1 case of endometrial pathology of grade Ⅰatypical hyperplasia ) .Postoperative symptoms were relieved in 7 cases (53.8%).Laparoscopic total hysterectomy was performed in 3 cases of adenomyosis complicated with secondary progressive dysmenorrhea (23.1%), 2 cases of endometrial proliferation associated with a breast cancer history (15.4%), and 1 case of endometrial atypical hyperplasia grade Ⅰ (7.7%). Conclusion After hysteroscopic TCRE, residual functional endometrium or future regeneration of endometrium may lead to late complications , which need further clinical diagnosis and treatment .

Objective To investigate the diagnostic value of hysteroscopy combined with B -ultrasonography for uterine incision diverticulum after secondary cesarean section . Methods From May 2012 to May 2013, hysteroscopy check was performed in 38 cases with a history of two times of caesarean sections . The hysteroscopic results and ultrasound images were analyzed retrospectively . Results Incision diverticulum was diagnosed in 34 cases by using diagnostic hysteroscopy combined with B-ultrasonography, with a diagnosis rate of 89.5%(34/38).There were 18 cases of mild diverticulum (47.4%), 16 cases of severe diverticulum (42.1%), and 4 cases of good healing (10.5%).Of the 16 cases of severe diverticulum , the distance from top to serosal surface was 1.6-6.0 mm, and the width was 3-17 mm.Preoperative transvaginal ultrasonography ( TVS) showed only 10 cases of uterine incision diverticulum in patients with severe diverticulum , providing a diagnosis rate of 26.3% (10/38).Compared TVS with hysteroscopy combined with B-ultrasonography , there was a significant difference (χ2 =31.091, P=0.000) in the diagnosis rate for uterine incision diverticulum . Conclusion Hysteroscopy combined with B-ultrasonography has a high diagnosis rate for the diagnosis of uterine incision diverticulum in patients with two times of cesarean sections , being worthy of clinical application as a minimally invasive examination method after cesarean sections .

Purpose To investigate the expression and significance of ArhGAP29 and E-cadherin in endometrial tissue of intrauterine adhesions (IUAs) and to explore their roles in the pathogenesis of IUAs.Methods The expression of ArhGAP29 and E-cadherin was detected by immunohistochemical PV 9000 two-step method.The correlation between ArhGAP29 and E-cadherin expression and clinical features was analyzed.Results (1) The immunoreactive score (IRS) of ArhGAP29 and E-cadherin in normal endometrial tissue were higher than those in IUAs endometrial tissue (P =0.017,P =0.004).(2) IRS of ArhGAP 29 and E-cadherin in moderate IUAs patients were higher than that in severe IUAs patients (P =0.020,P =0.026).In IUAs patients without amenorrhea,the IRS of ArhGAP29 and Ecadherin were higher (P =0.019,P =0.031) than that in IUAs patients with amenorrhea.(3) The decrease of ArhGAP29 expression had a significantly parallel relationship with the negative expression of E-cadherin (r =0.725,P ＜ 0.001).Conclusion The expression of ArhGAP29 and E-cadherin decreases in endometrial tissue of IUAs patients,which is related with degree of IUAs severity.ArhGAP29 and E-cadherin may participate in the IUAs formation.

Objective　To explore the relationship between hemolymph phenol oxidase and the melanization of Plasmodium yoelii oocysts in Anopheles dirus. Methods　An Anopheles dirus-Plasmodium yoelii system was used Anopheles dirus were divided into 3 groups, that is, non-blood-fedding (N), normal-blood-fedding (B) and infected-blood-fedding (I). The activities of MPO and o-DPO in hemolymph from 3 groups were determined with native polyacrylamide gel electrophoresis (PAGE) and density scanning at 5, 7, 11 and 15 d after blood feeding. Results　Both MPO and o-DPO activity were significantly higher in group I than group N and B (P<0.05). But with the melanization of Plasmodium yoelii oocysts, both MPO and o-DPO activity in group I were decreased in comparison with group N, especially on the 15 th day after infected-blood feeding. MPO and o-DPO activity in group B were significantly stronger than those of group N. Conclusion　Blood feeding and infection of Plasmodium yoelii both can activate the cascade. The heamolymph phenol oxidase may play an important role in the melanization of Plasmodium yoelii oocysts in Anopheles dirus.

OBJECTIVETo study the relationship between clinical and imaging features in neonates with hypoglycemic brain injury.

METHODSSixteen neonates with hypoglycemic brain injury received a MRI scan with the sequences of T1WI, T2WI and DWI within 48 hrs after admission. Of the 16 patients, 11 received second MRI scan at two weeks of their lives, and 3 received a third scan at ages of 1-5 months.

RESULTSRepeated seizures, lethargy and hypotonia were common clinical manifestations. Five severe hypoglycemia cases presented coma, respiratory failure and even cardiorespiratory arrest. The minimum mean value of whole blood glucose (WBG) in the 16 patients was 0.98+/-0.43 mmol/L, and that of the 5 severe cases was 0.72+/-0.42 mmol/L. EEG showed intermittent low voltage in the mild hypoglycemia cases. Flatten pattern and even electrocerebral silence was noted in the severe cases. Occipital and parietal cortexes (OPC) injuries were found in all of the 16 patients and 2 patients had concurrent periventricular white matter injury. A widespread involvement of cortex was found in the 5 severe hypoglycemia cases in which 1 showed widespread involvement of white matter, and 2 showed involvement of basal ganglia and thalamus. The 5 patients with widespread cortex injury and the 2 patients with OPC and periventricular white matter injury showed lower minimum WBG levels compared with those with OPC alone (0.71+/-0.35 mmol/L vs 1.19+/-0.42 mmol/L; t= 2.4124, P<0.05). The appearance of high-intensity signals on DWI was shown as early changes of signals in all of the 16 patients. The second MRI scan for 7 patients with OPC showed abnormal signals on T1WI and T2WI in 5 patients and abnormal signals on DWI in 3 cases. Cerebral atrophy and multicystic encephalomalacia were found in four patients with widespread involvement of cortex on DWI. In the follow-up one patient with OPC presented delayed myelination and one with concurrent white matter injury showed spastic diplegia. One patient with widespread involvement of cortex showed diffused encephalomalacia.

CONCLUSIONSThe severity of hypoglycemic brain injury demonstrated by serial MRIs relates to the severity of hypoglycemia. The occipital and parietal areas are the most vulnerable following hypoglycemia in neonates. Severe hypoglycemic brain injury manifests as a widespread involvement of cortex, or combined with white matter, or basal ganglia and thalamus. DWI can show early hypoglycemic brain injury.

A sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was applied for the quantification of each component: tetrahydropalmatine (THP), dehydrocorydaline (DHC), salvianolic acid B (SAB), ginsenoside Rg1, Re, Rb1 and Rd in the Chinese herbal component SSTG (Shuangshentongguan) with different combinations. The pharmacokinetic data were analyzed with WinNonlin 5.2 software. The results showed that combination can increase the THP AUC value while the AUC values of SAB, ginsenoside Rg1, Re, Rb1 and Rd were reduced. These results showed significant differences. The AUC value of ginsenoside Rb1 was increased when combined with Danshen or Yanhusuo, but reduced when combined with Danshen and Yanhusuo. The DHC concentration in serum was too low to be determined.

This study was aimed to investigate one case with rare type B(A) in ABO blood group by using serological and molecular biological methods, and analyze the cause of inconsistency resulting from multiple detections. The serological method was used to identify the serum type of ABO blood group, at the same time the PCR sequencing method was used to detect the genotypes. The results indicated that the group typing and reverse typing for the blood donor were inconsistent, the group typing was AB, the reverse typing was B. The ABO genotype was B(A) 04 /001. This genotype was involved in nt640A > G point mutation which caused valine replacing methionine at 214. It is concluded that the sample inconsistent between the group typing and reverse typing could be typed by molecular biological method, and the molecular basis of weak expression of ABO blood group is elucidated too.
