Infectious endophthalmitis refers to the acute suppurative inflammation of the uveal and retinal, with acute onset, severe symptoms, and poor prognosis.Early diagnosis and effective treatment is particularly important.Based on the way of intraocular infection, endophthalmitis can be divided into endogenous endophthalmitis and exogenous endophthalmitis.In the East Asian, liver abscess is the main source of endogenous endophthalmitis, and Klebsiella pneumoniae is the main pathogen.Liver abscess endophthalmitis is a serious cause of blindness caused by intraocular infection.A liver infection disseminated through hematogenous and the primary focus was hidden, which makes the disease was easy to be confused with immune related uveitis, causing high misdiagnosis rate, delaying the best time for diagnosis and treatment.In this article we reviewed the etiology, clinical features, diagnosis and treatment and prognosis of endogenous endophthalmitis caused by liver abscess.Clinicians should maintain a high index of suspicion to the endogenous endophthalmitis caused by liver abscess.

Objective To improve the capability of diagnosing and treating renal chromophobe cell carcinoma (RCCC) and the recognition of this subtype of renal cell carcinoma (RCC). Methods The clinical data of 15 cases of RCCC (10 men and 5 women) were analyzed.Their age ranged from 47 to 74 years,with a mean of 57 years. Radical nephrectomy was performed in all these cases. Results Postoperative pathological findings confirmed the diagnosis of RCCC.The pathologic TNM stage of RCCC was as follows:pT 1N 0M 0 in 6 cases,pT 2N 0M 0 in 5,pT 3bN 0M 0 in 2,pT 1N 2M 0 in 1 and pT 2N 2M 0 in 1.The pathologic grade of RCCC was G 2 in 10 cases and G 3 in 5.Eleven cases were followed up.During the follow-up of 2 to 31 months (mean, 19 months),1 died of heart attack,1 had local recurrence and 9 were surviving tumor free. Conclusions RCCC is a morphologically distinctive uncommon subtype of RCC.Radical nephrectomy is the first choice for the treatment of RCCC.Compared with other types of RCC at the same stage and of the same grade,RCCC has a better prognosis.

Objective To design and optimize the self-emulsifying drug delivery system ( SEDDS) of dihydromyricetin, and evaluate its quality in vitro. Methods The solubility of dihydromyricetin was measured in different oil phases,emulsifier and co-emulsifier solution. The best prescription was selected by comprehensively evaluating emulsification speed,particle size and drug loading via using the ternary phase diagram and orthogonal design test. Results The optimized formula of the self-emulsifying drug delivery system was oleic acidTween-80span-80N-butanol =1514714. Conclusion The optimized dihydromyricetin self-emulsifying drug delivery system significantly improves the solubility of dihydromyricetin, increases the physical and chemical properties of the formulation,and raises the dissolution of dihydromyricetin in artificial gastric fluid.

Objective To discuss the expression and mutation of β-catenin gene in breast carcinoma.Methods 119 breast carcinomas, 72 adenosis of breast tissues and 40 normal breast tissues were studied.Using immunohistochemistry studies to detect the expressions of β-catenin, then analyzing their relationship with the clinicopathological features of breast carcinomas. Gene mutation of β-catenin (exon 3) in 44 cases of breast carcinoma were analyzed by polymerase chain reaction (PCR) and then by direct sequencing.ResultsIn 40 cases of normal breast tissues, epithelial cells showed equally strong membranous of β-catenin protein at the cell-cell boundaries. The abnormal rate of β-catenin in breast carcinomas (78.15 %) was much higher than that of adenosis of breast tissues (44.44 %), the significant correlation was found (P＜0.01). The abnormal expression of β-catenin was associated with lymph node metastasis (P=0.031). Mutation of β-catenin gene was not detected in 44 cases of breast carcinoma, while the abnormal rate of β-catenin in 44 cases of breast carcinoma was 77.30 %. Conclusionβ-catenin abnormal expression could be considered as an useful marker for determining metastasis and prognosis of human breast carcinoma and for guiding treatment. β-catenin abnormal expression is not caused by β-catenin gene mutation, maybe by other mechanisms. It needs further study.

BACKGROUND:The treatment of limbs’ open fracture with severe soft tissue injury is very complicated. There are many wound exudates, high frequency of dressing change, and high infection rate. How to deal with the contradiction between wound treatment and fracture fixation is the considerable problem in clinical therapy. ＜br> OBJECTIVE:To explore the effect of external fixator combined with vacuum sealing drainage on limbs’ open fracture with severe soft tissue injuries. ＜br> METHODS:A total of 34 patients with limbs’ open fracture with severe soft tissue injuries were enrol ed in the First Affiliated Hospital, Xinxiang Medical Col ege from December 2009 to December 2010. There were 20 males and 14 females, with an average age of 36.6 years old. There were 10 cases of upper limb fracture and 24 cases of lower limb fracture. After debridement, cutaneous deficiency accounted for 1%to 6%of surface area. On the basis of external fixation, the wound received vacuum sealing drainage (treatment group;n=17) and conventional dressing (control group;n=17). According to limb swel ing and granulation growth, delayed suture, skin graft or flap to cover the wound were used. After treatment, infection rate of the wound and growth of granulation were observed. In accordance with wound healing and growth of granulation, curative effects were evaluated. ＜br> RESULTS AND CONCLUSION:In the treatment group, there were 11 cases of healing, 5 cases of effective effects, and 1 case of ineffective effect, with a total effective rate of 94%and the infection rate of about 15%. In the control group, there were 7 cases of healing, 6 cases of effective effects, and 4 cases of ineffective effects, with a total effective rate of 76%and the infection rate of about 40%. Significant differences in healing rate, total effective rate and infection rate were detected between the two groups (P＜0.05). The healing time of wound was 8.66-16.23 days in the treatment group and 15.68-22.36 days in the control group. The healing time was significantly shorter in the treatment group than in the control group (P＜0.05). It is thus clear that vacuum sealing drainage has obvious advantages in repair of limbs’ open fracture with severe soft tissue injury compared with the conventional dressing.

Objective To study the diagnosis and treatment of retroperitoneal schwannoma.Methods Clinical data of 11 cases of primary retroperitoneal schwannomas were analyzed retrospectively from February 1990 to September 2014.There were 6 males and 5 females,with a median age of 46 years,and the median tumor size was 9.6 cm (4.5-12.3 cm).Seven cases were revealled due to physical examination,3 cases were revealled due to ipsilateral lower back pain or discomfort,and 1 case was revealled due to right lower extremity numbness.There were no clinical manifestations of hypertension or appearance shape change,and there were no abnormal findings in routine laboratory and endocrine examinations.Radiological examination showed a retroperitoneal mass.There were 3 cases in the left adrenal gland,1 case in the right adrenal gland,3 cases in the lower pole of left kidney and 4 cases in the lower pole of right kidney.Four patients were initially diagnosed as adrenal tumors,and 7 patients were diagnosed as kidney tumors.Results All the 11 cases underwent surgical resection,with 7 cases of complete resection,1 case of capsule resection,2 cases of partial resection and 1 case of biopsy.The pathology of immunohistochemical staining showed S-100 positive in 10 cases of benign retroperitoneal schwannomas.During the follow-up period for 1.5-24 years (median 14 years),no recurrence and malignance was observed.One case of malignant retroperitoneal schwannoma died of multiple metastases in 17 months after opreation.Conclusions Primary retroperitoneal schwannoma is rare and preoperative diagnosis is difficult.Clinical manifestations and radiological findings are usually nondiagnostic,and histopathology is the only way for final diagnosis.Complete surgical resection is proved to be the best choice.

Objective To evaluate the efficiency and safety of transurethral plasmakinetic enucleation of prostate(PKEP) in the treatment of patients with benign prostate hyperplasia(BPH) after transrectal prostate biopsy(TRPB).Methods A total of 88 BPH patients who underwent PKEP in our hospital during Jan.2012 to May 2015 were retrospectively analyzed and followedup.38 patients underwent TRPB before PKEP were defined as TRPB group,and 50 patients underwent PKEP with no TRPB were defined as control group.The baseline data,perioperative data and postoperative follow-up outcomes were recorded and compared between the two groups.Results The mean age of the 88 patients were 69.7 years.Compared with control group,TRPB group showed that age was younger(t=2.62,P＜ 0.05)and prostate specific antigen(PSA) level was higher(t=13.64,P＜0.01).Operation duration was longer in TRPB group than in control group (93.6 ± 31.0) min vs.(77.9 ± 17.3) min (t =2.6 4,P ＜ 0.05).There were no significant differences in the preoperative data,blood loss,continuous bladder irrigation duration after operation and period of catheterization between two groups (all P ＞ 0.05).Trans-operative time was significantly shortened when the time interval between TRPB and PKEP is more than 4 weeks(P＜ 0.01),while blood loss was similar in the two groups(P＞ 0.0 5).There were no adverse events of blood transfusion,transurethral resection syndrome and injury of bladder or rectal in both two groups.There were no significant differences in maximum flow rate(Qmax),international prostate symptom score(IPSS) or quality of life(QOL) scores between the two groups at 3,6 and 12 months of follow up(all P＞ 0.05).Conclusions PKEP after TRPB is a safe and effective treatment for BPH patient.When the time interval between TRPB and PKEP is more than 4 weeks,the performing of PKEP operation would reduce the difficulty of operative procedure and increase the safety.

OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

Objective To evaluate the reasons for intrathecal administration of vincristine,the characteristics of patients with nerve damage,and the effective rescue measures and outcome prognosis.Methods Electronic literature databases,English and Chinese Paper Documents databases,and Network Engine were searched for Case Reports of inadvertent intrathecal injection of vincristine.SPSS 15.0 was used for statistical analysis.Results Analysis of 32 cases report showed that the intrathecal injection of vincristine in patients had adverse outcome.Of these cases 25 led to death,and survival of cases was associated with lower limb paralysis or quadriplegia.Fatalities appeared due to a progressively ascending myeloencephalopathy.Early recognition and immediate treatment with CSF drainage appeared to be the only intervention that had improved patients' survival.The survival curves of different surgical treatments,whether or not to use folic acid treatment,whether or not to use glutamate treatment,whether or not to use pyridoxinetreatment,was a significant difference.Conclusions Timely ventriculo-lumbar washout,using folic acid treatment and glutamate treatment appear critical.It is difficult to obtain satisfactory clinical outcome,so the key lies in the implementation of effective preventive measures.
