Objective To explore the clinical value of the Luo’s fornix cup in laparoscopic total hysterectomy. Methods A total of 7 patients with indications for hysterectomy from October 2004 to February 2005 was given laparoscopic total hysterectomy. During the operation, the Luo’s fornix cup was used for the orientation and dilatation of the vaginal fornix. Then the anterior vaginal fornix was circlewise incised by using a harmonic hook to extract the Luo’s fornix cup. Afterwards the posterior fornix was opened to remove the uterus by way of the vagina. And finally the vaginal stump was closed. Results All the operations were successfully completed. The operation time was 90~250 min. With the use of the Luo’s fornix cup, the operator could easily identify the top of the vaginal fornix, and avoid the damage of important neighbouring organs. No injuries of bladder, ureter, and rectum were noted. Conclusions The Luo’s fornix cup is a rational accessory instrument in laparoscopic hysterectomy, being worthy of recommendation.

Objective To observe the intervention effect of Ginkgo biloba extract EGb761 on tert-butyl hydroperoxide ( t-BHP)-induced injury in human umbilical cord-derived mesenchymal stem cells ( hUC-MSCs) . Methods Proliferation of hUC-MSCs after primary culture was detected by methyl thiazolyl tetrazolium (MTT) assay, and then the optimal concentrations of t-BHP and EGb761 for oxidative stress injured MSC model were screened. Cell apoptosis was assessed by flow cytometry after Annexin V-fluorescein isothiocyanatel propidium iodide ( Annexin V-FITC/PI) staining. Content of malondialdehyde ( MDA) and superoxide dismutase (SOD) activity in hUC-MSCs were evaluated, and the expression levels of p53 and p21Cip1/Waf1 were analyzed by real-time fluorescence PCR. Results Pretreatment with 10~200 mg/L of EGb761 for 3 hours reduced the sensitivity of hUC-MSCs to t-BHP ( 100 μmol/L) induced proliferation inhibition, while EGb761 over 100 mg/L had no significant effect on enhancing the protection of hUC-MSCs . EGb761 at 100 mg/L prohibited hUC-MSCs apoptosis and MDA accumulation in hUC-MSCs induced by 100μmol/L of t-BHP acting for 6 hours, maintained the enzymatic activity of SOD, and decreased the expression of p53 and p21Cip1/Waf1 in hUC-MSCs with t-BHP-induced injury. Conclusion EGb761 is capable of protecting hUC-MSCs against oxidative stress injury, and its mechanism is probably related with the modulation of p53/p21 signal pathway.

Background and purpose:There were reports that radiotherapy might intensify angiogenesis and result in the resistance of tumor to radiotherapy.Endostar,a new type rh-endostatin,may specifically inhibit angiogenesis and tumor growth,so it may reduce the resistance to radiotherapy.This study was to evaluate the inhibitory effect of Endostar in combination with radiation compared with cisplatin(DDP) plus radiation on lung adenocarcinoma A549 in BALB/c nude mice.Methods:We established A549 lung adenocarcinoma xenograft models.When the largest diameter of tumor reached 1.0 cm,all mice were randomized into 4 groups(n=6):control,radiation alone,radiation plus DDP,radiation plus Endostar.We measured the largest diameter and the vertical diameter of the tumors at different time points after treatment.At the 16th day,mice were executed and the tumors were subjected to removal for the analysis of apoptosis,and the expression level of basic fibroblast growth factor(bFGF) mRNA by reverse transcription-polymerase chain reaction(RT-PCR) and vascular endothelial growth factor(VEGF) were also detected by immunohistochemistry.Results:The tumor growth velocity of control,radiation alone,radiation plus DDP,radiation plus Endostar were(162?6)%,(131?8)%,(104?7)% and(108?11)% respectively(P0.05).The apoptosis rates of control,radiation alone,radiation plus DDP,radiation plus Endostar were(12.2?1.1)%,(16.5?0.8)%,(24.4?1.5)% and(20.5?1.9)%,respectively(P

Objective To investigate the effect of double versus single internal thoracic artery on sterna wound healing in coronary artery bypass grafting (CABG).Methods Patients undergoing CABG were randomly divided into experimental group (double internal thoracic artery group) and control group (single internal thoracic artery group) according to the number of internal thoracic artery used in operations.Experimental group:skeletonized double internal mammary arteries were harvested in all 50 cases (37 males and 13 females).Control group:skeletonized left internal mammary artery was harvested in all 50 cases (34 males and 16 females).Sterna wound healing and post-operational complications were observed.Results The incidence of poor sterna wound healing and volume of drainage after operation in the experimental group were more than those in the control group [volume of drainage on the first day:(350.67±56.86)ml vs (240.72 ±48.35)ml;total volume of drainage:(595.65 ± 102.35) ml vs (398.85 ± 75.84) ml;poor sterna wound healing rate:20％ vs 0;P ＜ 0.05 or P ＜ 0.01].The sterna wound healing rate of high-risk patients between two groups had significant difference (8 cases vs 0 case,P ＜ 0.05).Conclusions Compared to the single internal mammary artery grafting,the double internal mammary artery grafting increased the risk of sternal wound healing.

Objective To analyze the causes for the thigh pain after treatment of femoral trochanteric fractures by proximal femoral nail antirotation Ⅱ( PFNA Ⅱ) . Methods Included in this ret-rospective study were 236 patients who had been treated by us for femoral trochanteric fracture from October 2011 to December 2015. They were 103 men and 133 women, aged from 42 to 86 years (average, 50. 3 years) . According to AO classification, 13 cases belonged to type 31-A1. 2, 32 to type 31-A1. 3, 35 to type 31-A2. 1, 27 to type 31-A2. 2, 33 to type 31-A2. 3, 38 to type 31-A3. 1, 39 to type 31-A3. 2 and 19 to type 31-A3. 3. All the fractures were single, fresh and closed and treated with PFNAⅡinternal fixation. Results This cohort was followed up for 8 to 26 months (average, 13. 2 months). Nonunion occurred in one case who had to accept artificial hip replacement. The remaining 235 cases obtained bony union after 22 to 39 weeks (average, 29. 3 weeks). By the Harris evaluation at final follow-ups, the affected hips scored from 81 to 93 points (average, 85. 1 points) . Post-operative thigh pain was reported in 19 cases (8. 05％) . The causes included varied anatomic morphology of the proximal femur in 6 cases, distal defects of the intramadullary nails in 4, insufficient stability of internal fixation or uneven biomecanical distribution in 3, unskillful operation in 2, and severe oesteoporosis in 4. Avascular necrosis of femoral head was not observed during follow-ups. Conclusions Postoperative thigh pain is worthy of serious atention from orthopaedists following PFNA Ⅱtreatment of femoral trochanteric fractures. PFNA Ⅱshould be modified according to the specific Chinese features of the proximal femur, especially in the respects of anterior arch and distal structure of the main nail and lateral declination as well.

Objective By analyzing the clinical and radiographic manifestations of calcium pyrophosphate deposition disease (CPDD) to improve the recognization of the disease.Methods Clinical features,diagnosis and treatment of an old female patient with CPDD was reported with literature review.Results An old female patient presented with swollen and pain on the right knee without obvious causes eight years ago,which was characterized by slightly reddness of joint surface,warm of local skin.Thcn she gradually developed swollen and pain in left knee,right ankle,both wrists,bilateral meta-carpophalangeal (MCPJ) and right elbow joints with few joint symptoms and the joints swollen and pain could relieved spontaneouslyitself in about one week.X-ray showed the thin strip of cartilage calcifications in wrist triangular fibrocartilage disc,meniscus of knee and the pubic symphysis were parallel to the surface of cartilage.Examination of microscopy with refractive filter demonstrated that short rod crystals refraction in joint fluid.CPDD was diagnosed and treated with flushing of joint cavity and injections of betamethasone as well as nonsteroidal anti-inflammatory drug orally.Symptoms relieved after therapy.Conclusion Understanding the disease characteristics of CPDD is beneficial to for accurate diagnosis and treatment.

In order to investigate the inhibitory effects of Endostar (rh-endostatin, YH-16) in combination with radiotherapy on lung adenocarcinoma A549 in mice and the interaction mechanisms of combined therapy, the transplantation tumor models of A549 lung adenocarcinoma were established. When the largest diameter of tumor reached 1.0 cm, all nude mice were randomly divided into 4 groups: Endostar group, radiotherapy group, radiotherapy plus Endostar (combined treatment) group, and control group (n=6 in each group). The largest diameter and the vertical diameter of tumor were measured at different time points. At the 16th day, mice were executed, and the tumors were applied to analysis of rate of tumor cell apoptosis, and the expression levels of basic fibroblast growth factor (bFGF) mRNA were detected by reverse transcription-polymerase chain reaction (RT-PCR) and those of vascular endothelial growth factor (VEGF) by immunohistochemistry. The results demonstrated that the rate of tumor inhibition in combined treatment group was higher than that in other groups. And the rate of tumor cell apoptosis in combined treatment group was also higher than that in other groups. Meanwhile, the levels of bFGF mRNA and VEGF expression in combined treatment group were lower than those in other groups. It was concluded that Endostar obviously enhanced the curative effectiveness of radiotherapy on lung adenocarcinoma A549 in mice. The underlying mechanisms may involve the down-regulation of bFGF mRNA and VEGF expression to inhibit angiogenesis by Endostar and the cooperative effect of Endostar and radiotherapy to synergistically promote tumor cell apoptosis. And Endostar inhibits angiogenesis by down-regulating the expression of bFGF mRNA and VEGF.

Objective To investigate the clinical and imaging features of patients with calcium pyrophosphate deposition (CPPD).Methods The clinical data and X-rays material of knee joint of 20 patients with CPPD were retrospectively analyzed.Pearson/Spearman's correlations analysis was used for statistical analysis with software version 15.0.Results The 20 patients with CPPD had demonstrated that the typical accumulation of calcium,which accounted for about 1.5％o(20/13 536) among patients over 55 years old who had knees X-ray at the same period in Chaoyang Hospital.Female patients of CPPD was 80％ (16/20).Seventeen patients completed follow-up visits.The age of onset for CPPD ranged from 44 to 85 years old,the percentage of CPPD patients over 70 years old was 71％(12/17).Among the 17 cases of followed,14 cases (82％) were patients with paroxysmal arthritis with the initial site of knee joint (79％) and ankle joint (21％).Most patients suffered from moderate to severe pain,while some might have local congestion and increased skin temperature.Five patients had more than two different joints attacked by arthritis.The distribution of the affected areas was knee,ankle,hip,elbow,wrist and metacarpophalangeal joints.The median number of attack was 1.5 times a year,and the median duration of attack was 8.5 days.Among the 14 patients,Six cases of them had no recurrence after treatment,but six cases had recurrent attacks within a year.The imaging of lateral articular facet showed that calcium deposit was extended and thickness of calcification was increased.Plus osteophyte formation stage was 100％ with an average of 3.0±1.6 and 85％ sclerosis of articular facet.The rate of attacks of arthritis had a positive correlation with calcium deposition range of lateral articular facet (r=0.663,P=0.010) and a negative correlation with sclerosis of articular facet (r=-0.548,P=0.042).Conclusion Old patients with paroxysmal joint pain,patients with knee joint or other big joints as the initial joints involved,patients with long duration disease,patients who had more than two joints at attack and patients with calcium deposition in imaging,should be suspected for CPPD clinically.Moreover,patients with a wide range of calcium deposition are high likely to suffer from recurrent arthritis attack.
