Chinese Journal of Postgraduates of Medicine 2015;38(3):178-180
Objective To investigate difference of clinical curative effect between laparoscope combined with choledochoscope and traditional laparotomy in treatment of cholecystolithiasis and choledocholithiasis.Methods The clinical data of 80 patients with cholecystolithiasis and choledocholithiasis were retrospectively analyzed,among whom 48 patients were given laparoscopic cholecystectomy (LC) ± laparoscopic common bile duct exploration (LCBDE) (observation group),and 32 patients were given traditional laparotomy (control group).The curative effect was compared between 2 groups.Results There were no statistical differences in operating time,calculi clearance rate and cost of hospitalization between 2 groups (P > 0.05).The intraoperative bleeding,postoperative length of hospital stay,and rate of postoperative complication in observation group were significantly lower than those in control group:(28 ± 5) ml vs.(32 ± 11) ml,(6.0 ± 1.1) d vs.(7.0 ± 1.2) d,4.17% (2/48) vs.18.75% (6/32),and there were statistical differences (P < 0.05).Conclusion Laparoscope combined with choledochoscope is an effective treatment method of cholecystolithiasis and choledocholithiasis.

OBJECTIVE: To investigate the clinical outcomes of artificial bone (hydroxyapatite) and bone cement implantation in treating young patients with avascular necrosis of the femoral head caused by different reasons. METHODS: A total of 18 patients (23 hips) with Ficat stage Ⅲ and Ⅱ avascular necrosis of the femoral head were treated with dead bone debridement, artificial bone and cement implantation in Department of Orthopedics, Third Affiliated Hospital of Guangxi Traditional Chinese Medical College from October 2003 to July 2008. The patients were followed up for 24.6 months (ranging 3 months to 5 years). The affected hip function was evaluated by modified Merled'Aubigne Scores and X-ray. RESULTS: Mean hip scores improved significantly from 11.65 to 15.09 after surgery. Postoperative radiographs demonstrated the improved collapse and restoration of femoral head sphericity. The femoral heads of most patients remained the appearance after surgery, and the necrosis range did not enlarge. The patients were satisfactory to the treatment results. CONCLUSION: Artificial bone and cement implantation could restore head sphericity and prevent further collapse. The method can be used as an alternative for treatment of avascular necrosis of femoral head at Ficat stage Ⅱ and Ⅲ, especially for young patients.

Objective To explore the effect of individualized chemotherapy plans which was designed depend on secific genetic characters in patients with advanced cancer.Methods The surgery or biopsy specimen samples from 25 patients with advanced recurrent tumors (study group) were analyzed.Different gene mRNA expressions were detected by PCR and sequencing.According to detection results,the most appropriate chemotherapy would be applied on 25 cases patients of study group.The chemotherapy from traditional experience and evidence-based medical evidence were applied for 20 cases patients of control group.The difference of RR and disease control rate (DCR) between two groups were compared.Results The DCR and RR were 84 % (21/25) and 44 % (11/25) in study group,35 % (7/20) and 15 % (3/20) in control group.The DCR and RR in study group were significantly higher than those in control group (P < 0.01).Conclusion Individualized chemotherapy could improve the efficient and prolong the survival period of the patients with advanced recurrent tumors.

Objective Non-affinity methods were used to purify transferrin(TRF)with high purity from human serum,and the immunogenicity of TRF was evaluated by immunizing New Zealand rabbits.Methods Firstly,TRF was extracted from serum by precipitation with ammonium sulfate and then purified by two-step anion exchange chromatography.Results SDS-PAGE purity of the prepared TRF was similar with the control pure product,and the HPLC purity reached to 96.8% with a yield of 78.6%.For the same batch of TRF sam-ple,the ratio between the activity concentration determinated using TRF kit(immunoturbidimetry method) and the protein concentration determinated using uv-spectrophotometric method was about 0.95,which indica-ted that the prepared TRF for antigen could react well with the TRF antibody included in the TRF kit.Final-ly,New Zealand rabbits were immunized using the purified TRF,and the titer of the rabbit anti-serum could reach 1:128 000 after four time immunization,which also indicated that the prepared TRF had good immuno-genicity.Conclusion The TRF with high purity had good antigen reactivity and immunogenicity to prepare anti-T RF antibody by immunizing rabbits,w hich could provide qualified materials for the production of T RF kit(immunoturbidimetry method).

Hydrocephalus is often treated with a cerebrospinal fluid shunt (CFS) for excessive amounts of cerebrospinal fluid in the brain. However, it is very difficult to distinguish whether the ventricular enlargement is due to hydrocephalus or other causes, such as brain atrophy after brain damage and surgery. The non-trivial evaluation of the consciousness level, along with a continuous drainage test of the lumbar cistern is thus clinically important before the decision for CFS is made. We studied 32 secondary mild hydrocephalus patients with different consciousness levels, who received T1 and diffusion tensor imaging magnetic resonance scans before and after lumbar cerebrospinal fluid drainage. We applied a novel machine-learning method to find the most discriminative features from the multi-modal neuroimages. Then, we built a regression model to regress the JFK Coma Recovery Scale-Revised (CRS-R) scores to quantify the level of consciousness. The experimental results showed that our method not only approximated the CRS-R scores but also tracked the temporal changes in individual patients. The regression model has high potential for the evaluation of consciousness in clinical practice.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis. The lack of comprehensive surveys of the current literature, however, impedes the progress of this domain. Existing research perspectives, as well as the architectures, tasks, datasets, and performance measures examined in the present literature, are reviewed in this work, and we also provide a brief description of possible future directions in the field, aiming to provide researchers and healthcare professionals with a detailed summary of existing academic research and to provide rational insights to facilitate future research.
