Objective:This study aimed to observe the curative effect and adverse reaction of docetaxel combined with intraperitoneal cisplatin chemotherapy and hyperthermia treatment of advanced ovarian cancer. Methods:A total of 83 patients with inoperable and recurrent advanced ovarian cancer were randomly divided into two groups:hyperthermia group and control group. The hyperthermia group consisted of 42 cases of docetaxel chemotherapy immediately treated with intraperitoneal cisplatin chemotherapy combined with abdominal local hyperthermia. The control group included 41 cases of docetaxel chemotherapy and intraperitoneal cisplatin chemotherapy treatment only. Results:The total efficiencies of the hyperthermia treatment group and the control group were 81%and 58.1%, respectively, which showed that the total efficiency significantly improved (P<0.05). The ascite control rates were 78.3%and 66.7%and CA125 decreased by 84.2%and 61.5%for the hyperthermia and control groups, respectively. The main adverse reactions were gastrointestinal reaction and bone marrow suppression. However, differences were not statistically significant. Conclusion:Docetaxel combined with cisplatin intraperitoneal perfusion hyperthermia significantly improved the curative effect on advanced ovarian cancer without increasing toxicity, which indicates that it is a treatment worth popularizing.

OBJECTIVETo explore the changes of peripheral blood lymphocyte subsets in patients with acute hydrogen chloride gas poisoning.

METHODSWhen the patients were admitted or on the secondary day, the percentages of total T-cell lymphocyte subsets (CD(3)(+)CD(19)(-)), CD(4)(+)T cells (CD(3)(+)CD(4)(+)), CD(8)(+)T cells (CD(3)(+)CD(8)(+)), B cells (CD(3)(-)CD(19)(+)) and NK cells (CD(3)(-)CD(16)(+)CD(56)(+)), and the ration of CD(4)(+)/CD(8)(+) in 37 cases with acute hydrogen chloride gas poisoning and 49 healthy controls were detected with flow cytometer.

RESULTSThe total T-cell percentage and total CD(4)(+)T cell percentage in 37 cases were significantly lower than those in 47 controls (P < 0.05). The percentages of NK cells and B lymphocytes in 37 cases significantly increased, as compared with controls (P < 0.05). The ration of CD(4)(+)/CD(8)(+) in 37 cases significantly decreased, as compared with controls (P < 0.05).

CONCLUSIONThe lymphocyte subsets in the patients with acute hydrogen chloride gas poisoning changed, which could influence the immune function of patients.

Objective To investigate the relationship between the expression of decay receptor 3 (DcR3) and the eliniealpathological parameters in human gastric carcinoma. Methods The expression of DcR3 was examined by RT-PCR in a series of 41 human primary gastric carcinomas and 41cases of normal tissue adjacent to tumor. Multiple clinical pathological factors were analyzed according to their relation with the expression of DcR3. Results The positive rate of expression of DcR3 was 56 %(23/41) in human gastric carcinoma. The expression of DcR3 in gastric carcinoma was significantly higher than that in normal tissues adjacent tumor. The expression of DcR3 was significantly correlated with different degrees of differentiation, lymph node metastasis and TNM staging (P <0.10), but there was no significant difference in DcR3 and other clinical pathological features such as tumor position and invasion depth (P>0.10). The multiple linear regression equation was Y=0.432-0.208X1+0.098X2+0,086X3. Conclusion DcR3 expression can be highly found in gastric carcinoma. The abnormal expression of DcR3 may promote tumorigenesis and progression. DcR3 may be important in evaluating the tumor differentiation, infiltration depth, lymph node metastasis and TNM staging of human gastric carcinoma.

Objective: To explore the relationship between platelet counts at admission and in-hospital mortality in patients with type A acute aortic dissection (AAD). Methods: We investigated 183 consecutive patients with CT conifrmed diagnosis of type A AAD treated in our hospital from 2012-02 to 2013-05. There were 126 (68.9%) male and the patients were divided into 3 sets of groups.①In-hospital surviving group,n=157 and In-hospital death group,n=26.②According to platelet counts, the patients were divided into 5 groups: Q1 group, platelet counts ≤ 119×109/L,n=36, Q2 group, platelet (120-149) ×109/L,n=37, Q3 group, platelet (150-173)×109/L, n=36, Q4 group, platelet (174-228)×109/L,n=37, Q5 group, platelet >228×109/L,n=37.③At admission, platelet ≤ 119×109/L,n=36 and platelet >119×109/L,n=147. In addition, the patients were further divided into another 4 groups based on operative condition: platelet ≤ 119×109/L with operation,n=18, without operation,n=18; platelet > 119×109/L with operation,n=96, without operation,n=51. The basic information at admission including platelet counts, WBC and D-dimer were studied in all groups, the primary endpoint was in-hospital mortality. Results: The overall in-hospital mortality was 14.3%. Compared with In-hospital surviving group, the In-hospital mortality group had decreased platelet counts, lower blood pressure and higher level of D-dimer. The mortality in Q1 group (38.9%) was higher than those in Q2, Q3, Q4 and Q5 groups (10.8%, 11.1%, 8.1% and 2.7%), allP<0.001. The risk of death in Q5 group was higher than Q1 group (HR=11.2, 95% CI 2.13-123.3,P=0.007). With adjusted age, gender and other relevant factors, when platelet counts ≤ 119×109/L, the risk of in-hospital mortality with Cox multivariate model I analysis was (HR3.90, 95% CI 1.67-9.09,P=0.002), with Cox model II was (HR=2.67, 95% CI 1.15 -6.19,P=0.023). Conclusion: AAD patients with admission platelet counts ≤ 119×109/L had the high risk of in-hospital death, even with operation, lower platelet counts was still related to in-hospital death.

Objective To explore the distribution rule of metastatic lymph node in nasopharyngeal carcinoma (NPC) by magnetic resonance imaging (MRI).Methods 315 histopathologically proved NPC patients were studied retrospectively.All patients had had their nasopharynx scanned by MRI with plain and contrast enhanced sequences.The distribution of lymph node was divided into six cervical levels plus retro- pharyngeal nodes(RN) according to RTOG guidelines proposed in 2003.Results 254 out of 315 patients (80.6%) had lymph node involvement,with 81 in the right neck alone,72 left neck alone,and 101 both necks;73 in RN alone,21 neck node alone,and 160 both necks and RN node.Skip metastasis was found in only 4 patients (1.6%).There was significant difference in BN metastasis between the primary tumor be- ing located merely on the superior/posterior wall and lateral wall (78% vs 49%,P＜0.01).The incidence of lymph node metastasis in T1,T2,T3 and T4 patients was 73.5%,91.2%,71.9%,73.5% (P＞0.05), respectively,without significant difference between early or advanced T stage in node distribution (P＞0.05).Conclusions The incidence of lymph node metastasis is high in nasopharyngeal carcinoma,with retropharyngeal node being the most commonly involved,but the incidence of skip metastasis is very low. There is no significant difference between T stage and the incidence of lymph node metastasis.So is the dis- tribution of metastatic node.

Objective To investigate the morphological features of normal lumbar dorsal root ganglia using a three-dimensional(3D)coronal MR imaging.Methods One hundred and fifteen volunteers were included.Ages ranged from 15 to 75 years,with a mean of 40 years.Coronal 3D fast field echo(FFE) with water selective excitation(Proset)MR examination of 1150 dorsal root gangha were underwent at nerve root levels from L1 to L5.The source coronal images were further reconstructed into a series of rotational alignment coronal images with an interval angel of 12 degree using maximum intensity projection(MIP) technique.All DRGs of bilateral spinal nerve from L1 to L5 were morphologically analyzed on the original and MIP images including qualitative evaluation of the location,signal intensity,architecture and quantitative dimensional measurement.Results There were 225,225,219,210 and 160 foraminal ganglia from L1 to L5 level,respectively.The incidence of intraspinal ganglia from L3 to L5 gradually increased with a maximum at L5 level of 29.1%(X~2=188.371,P

Objective To report the development of clinical symptoms in a Chinese family with autosomal dominant progressive external ophthalmoplegia(adPEO).Methods Electromyologram and muscle biopsy were performed in the proband and 4 family members with the disease.Results The proband was a 57 year-old woman,who developed bilateral ptosis after the age of 30,external ophthalmoplegia after the age of 35 years old,weakness of extremities at the age of 37 years old and bulb palsy with palmus at the age of 47 years old.In the family there were 20 male and female members from five generations.All of them complained about bilateral ptosis between 26—33 years old,external ophthalmoplegia(12/15)and weakness of all extremities(14/15)between 35—45,facial and masticatory weakness(9/9)as well as dysphagia(8/9)between 44—60,accompanied with heart lesions(4/7)after 50 years old.Some patients died due to cardiac impairment.Electromyologram showed myopathic abnormalities in the examined patients. The main myopathological changes were ragged red fibers,cytochrome c oxidase negative fibers and ragged blue fibers in succinate dehydrogenase staining.Conclusions The adPEO started from extra-ocular muscles to limbs,finally facial and bulbar muscles.Heart lesions were presented in late stage and lead to death in some members.The developing process of symptoms suggested that we should pay more attention to cardiac manifestations in this disease.

OBJECTIVETo investigate MRI findings of osteochondral lesions in the talus;to evaluate the value of MRI in diagnosing and determining the stage of osteochondral lesions;to analyze the follow up clinical value of MRI in osteochondral transplantation of autologous bone.

METHODSA total of 79 patients from February 2013 to March 2015 had been retrospectively analyzed. All the patients were treated in our hospital. The ankle arthroscopy results were used as the reference standard, and the accuracy of MRI in diagnosis and Hepple staging had been investigated. Fifteen patients with cartilage transplantation of autologous bone were followed up with MRI examination and evaluation of cartilage repair score(MOCART) after one year. The values of MRI in the postoperative follow up were analyzed.

RESULTSHepple staging of 79 patients was shown as follows:7 cases of stage I, 12 cases of stage II, 24 cases of stage III, 16 cases of stage IV, and 20 cases of stage V. Ankle arthroscopy grading of 59 patients in this group(in addition of 20 cases of stage V):2 cases of grade A, 2 cases of grade B, 4 cases of grade C, 14 cases of grade D, 22 cases of grade E, and 15 cases of grade F. The accuracy rate of MRI in determining Hepple V was set at 100%, and Hepple stage I corresponds to the arthroscopic A, B, C stage, stage II corresponds to D stage, stage III corresponds to E stage, stage IV corresponds to F stage. The accuracy rate of MRI in determining Hepple stage I to IV was 87.5%, 85.7%, 95.4% and 93.3% respectively. After cartilage transplantation of autologous bone, MRI of 15 patients showed cartilage surface in transplanted area was smooth, bone healed well, and the surrounding edema disappeared. The MOCART was 30 to 80 scores with an average score 59.0±15.6;9 cases of these 15 patients were(9/15, 60%) higher than 60 score.

CONCLUSIONSMRI plays a significant role in clinical diagnosis and staging of the talus osteochondral injury. As a method of long term follow up after cartilage transplantation, MRI can well evaluate the rapair of the postoperative osteochondral injury.

The study is to design chitosan-coated pilocarpine nitrate submicro emulsion (CS-PN/SE) for the development of a novel mucoadhesive submicro emulsion, aiming to prolong the precorneal retention time and improve the ocular absorption. CS-PN/SE was fabricated in two steps: firstly, pilocarpine nitrate submicro emulsion (PN/SE) was prepared by high-speed shear with medium chain triglycerides (MCT) as oil phase and Tween 80 as the main emulsifier, and then incubated with chitosan (CS) acetic solution. The preparation process was optimized by central composite design-response surface methodology. Besides the particle size, zeta potential, entrapment efficiency and micromorphology were investigated, CS-PN/SE's precorneal residence properties and miotic effect were especially studied using New Zealand rabbits as the animal model. When CS-PN/SE was administered topically to rabbit eyes, the ocular clearance and the mean resident time (MRT) of pilocarpine nitrate were found to be dramatically improved (P < 0.05) compared with PN/SE and pilocarpine nitrate solution (PNs), since the K(CS-PN/SE) was declined to 0.006 4 +/- 0.000 3 min(-1) while MRT was prolonged up to 155.4 min. Pharmacodynamics results showed that the maximum miosis of CS-PN/SE was as high as 46.3%, while the miotic response lasted 480 min which is 255 min and 105 min longer than that of PNs and PN/SE, respectively. A larger area under the miotic percentage vs time curve (AUC) of CS-PN/SE was exhibited which is 1.6 folds and 1.2 folds as much as that of PNs and PN/SE, respectively (P < 0.05). Therefore, CS-PN/SE could enhance the duration of action and ocular bioavailability by improving the precorneal residence and ocular absorption significantly.
