ObjectivesTo compare operative characteristics, postoperative residue, recurrence, and pregnancy outcome between laparoscopic myomectomy (LM) and transabdominal myomectomy (TAM),and investigate the favourable surgical approach in women with uterine myomas. MethodsFrom Jan 2008 to Dec 2008, 313 women undergoing LM and 148 women undergoing TAM were studied retrospectively in Peking Union Medical College Hospital. The patients' general information, including the largest diameter,mean numbers and weights of excised myomas, peri-operative characteristics (operating time, blood loss,and hemoglobin decrease), and residue, recurrence of myoma, and pregnancy outcome were compared and analyzed. Results The largest diameter, mean numbers and mean weight of myomas removed were larger in TAM group [( 7.6 ± 3.0) cm, (5.6 ± 5.5 ), ( 308 ± 364) g, respectively]than those in LM group [(6.8±2.0) cm, (2.4 ±2.1), (140 ± 109) g, respectively; P＜0.01]. While the extension of operating time [(89±32) versus (74 ±35) min], increased blood loss [(239 ±251 ) versus ( 149 ±252) ml]and hemoglobin decrease [(22 ± 14) versus ( 15 ± 12) g/L], and longer hospital stay [(6. 4 ± 1. 6)versus (4. 4 ± 1.3) d]were observed in TAM group when compared with those in LM group ( P ＜0. 01 ).However, the residue rate of LM and TAM was 2. 6％ versus 1.4％ respectively ( P = 0. 5130 ) ; the recurrence rate of LM and TAM was 11.1％ versus 12. 3％ (P ＞ 0. 05 ) ; the pregnancy rate of LM and TAM was 49. 2％ versus 9/13 separately, the difference was not statistically significant ( P = 0. 2330 ). The number of myomas removed was the significant risk factors associated with recurrence ( OR = 2. 805, 95％CI: 1. 192 -6. 601, P = 0. 0180). No uterine rapture occurred during pregnancy. ConclusionsBoth LM and TAM are effective surgical approaches for the patients with leiomyoma who desire to pregnancy, or to retain the integrity of their uteruses. Most of uterine myoma could be treated through laparoscopy. The residue rate of LM is higher than that of TAM. However, the short term recurrence rates of LM and TAM are similar. Multiple myomas is the risk factor associated with recurrence after myomectomy. The pregnancy rates are comparable between LM and TAM groups.

300mmH2O), non-purulent CSF with pleocytosis up to 2700?106/L, increased polykaryocytes in the early stage, normal or obviously high total protein level, normal glucose and chloride level, and negative laboratory examinations (such as culture-and smear-examination of Mycobacterium tuberculosis, adenosine deaminase, anti-TB antibody, immuno-dot-blot assay MycoDot and PPD assay). In this series of 167 patients, 7 of them died (3.7%). Conclusions The findings in CSF examination in most patients with tuberculous meningitis may show atypical findings, therefore it should be emphasized to repeat the analysis of CSF in order to obtain an accurate diagnosis of tuberculous meningitis.

Objective To explore the operative cooperation of the intra-extra cranial bypass operation of the intracranial giant aneurysms. Methods A retrospective analysis of 7 patients who had intracranial giant aneurysm and received the intra-extra cranial bypass operation from October 2014 to June 2016. All preoperative and intraoperative nursing points of operative cooperation were analyzed. Results The post-operative digital subtraction angiographies of 7 patients without any perioperative nursing complications showed enough flow in the bypass arteries. Conclusions Operative multi-incision managing, positive temperature intervening, special instruments using and thrombosis preventing play very important roles in the nursing points of the successful operative cooperation.

A new minimally invasive gallbladder-preserving operation has emerged for the treatment of gallbladder stones,but fundamentally it is a replica of the previous gallbladder preservation method.The gallbladder aids in digestion but is not essential for life.Its function should not be exaggerated and should not instigate trivial reasons for its preservation.Most patients undergoing cholecystectomy maintain a good quality of life.The causes,mechanisms,and prevention of gallstone formation remains mysterious,so a high recurrence rate after gallbladder-preserving operation is difficult to avoid.A full cholecystectomy can avoid recurrence complications and the benefits outweigh the risks.A discussion of the benefits and complications must be initiated to evaluate both treatment modalities for gallstones.

A pot experiment was conducted to study effect of drought stress on leaf physiological characteristics and growth of one year old Stellaria dichotoma seedlings. The result showed that plant height and shoot dry weight significantly decreased with decrease in soil water content; however, root length and root dry weight increased at light drought stress and decreased at severe drought stress. The result also showed that with the decrease of soil water content, proline content in S. dichotoma leaves decreased then increase, while solube protein content decreased. Activities of SOD and POD in S. dichotoma leaves significantly decreased as soil water content decreased, while activity of CAT significantly decreased at severe drought stress. Membrane permeability in S. dichotoma leaves increased, while MDA content decreased then increased as soil water decreased. These results suggest that S. dichotoma had osmotic stress resistance ability and reactive oxygen scavenging capacity at light drought stress, which caused S. dichotoma growth was no inhibited at a certain extent drought stress.

OBJECTIVETo study the effect of different composition structures of total paeony glycoside (TPG) component and total phenolic acid of Ligusticum chuanxiong ( TLPA) on sodium dithionite (Na2S2O4) -induced human umbilical vein endothelial cells (HUVEC) hypoxic injury. The baseline geometric proportion was used to design different components structure. And then the best structure of components by cell injury model were optimized.

METHODA HUVEC hypoxic injury model was established by being induced of Na2S2O4. Cell viability was measured by MTI colorimetric method, intracellular superoxide dismutase (SOD) activity, malondialdehyde (MDA), lactate dehydrogenase( LDH) levels, nitric oxide (NO) contents were measured by kits. At last, Western blot analysis was used to detect the expression of two proteins, Bcl-2 and Bax.

RESULTCompared with the model group, TPG component, TLPA component at different composition structures can significantly increase SOD activity and decrease MDA, LDH, NO levels (P < 0.01, P < 0.05). Paeoniae Radix Rubra and Chuanxiong Rhizoma components can downregulate the expression of Bax protein and upregulate the expression of Bcl-2 protein. The ratio of Bcl-2 and Bax was significantly increased (P < 0 01, P < 0 05), it means that cell apoptosis was inhibited. The results indicate that among all the component composition structures, TPG and TLPA component at the proportion of 8: 2 had the best protection on hypoxic injury of endothelial cells.

CONCLUSIONTPG component and TLPA component can resist HUVEC hypoxia injury, the protective effect was the most evident under the structure of 8: 2, which may be due to the inhibition of intracellular lipid peroxidation and cell apoptosis.
