Regarding the prevention and treatment of hepatocellular carcinoma (HCC) recurrence after curative resection,surgeons do not have a clear consensus to evaluate the risk factors of recurrence and effectiveness of surgical resection.Therefore,postoperative HCC recurrence patterns were reviewed in this article,including differentiating intrahepatic metastasis (IM) and multicentric occurrence (MO),which play a key role in manifesting recurrence and patient prognosis.Additionally,the definitions of small HCC and curative resection,and the prophylactic and therapeutic values of anatomic resection and repeated hepatectomy in patients with recurrent HCC were reviewed.Fully understanding these issues might allow for a more objective,precise,and consistent clinical assessment of HCC.

Objective To analyze the results of sputum culture from smear-positive pulmonary tuberculosis cases after treatment for 2 months.Methods Sputum specimens from newly diagnosed 147 smear-positive pulmonary tuberculosis cases after treatment for 2 months were fast cultured by BacT/ALERT 3D.Poeitive cultures were further detected by HAIN test in Zhejiang Provincial Center for Disease Control and prevention and compared with L-J meditun.Results Mycobacteria were found in 45 specimens by Bact/ALERT 3D in contrast to 22 by Lonswtein-Jenson method.The median time was 19.3 days for the whole Bact/ALERT 3D test while the whole procedure would cost 3 months for traditional L-J test.Conclusion Results from sputum smear could not reflect tuberculosis progress properly while BacT/ALERT 3D fast culture would help to find drug resistant patients promptly and accurately.

Objective: To summarize the experience of surgical treatment of subaortic stenosis. Methods: 70 patients with subaortic stenosis were treated surgically. The diagnosis was made by echocardiography, left ventricular catheterization and angiography. There were 46 males and 24 females. The mean age at operation was 11.8 years (range 3 to 46 years). 64 patients had discrete stenosis and 6 had tunnel stenosis. For the discrete stenosis cases, simply resection of stenosis membrane was done in 58 cases and plus myoctomy in 6 cases. For the tunnel stenosis cases, left ventricular muscle was resected to relieve obstruction. In 59 patients combined cardiovascular malformation were corrected at the same time. Results: There were two postoperative deaths. Mitral valve injury occurred in 1 patient. The mean systolic gradient of left ventricle to aorta was 7.5 mmHg with a range of 0-30 mmHg in 38 cases after operation. The 1-, 3-, 5-, 10-, 20-year follow-up rate was 83%, 77%, 68%, 45%, and 9%,respectively. All patients were asymptomatic postoperatively. No reoperation was required. Conclusion: Once subaortic stenosis was diagnosed, operation should be done. Preoperative echocardiography and routine exploration of the root of aorta should be done during operation are in diagnosing. The key point of the operation that left ventricular outflow tract should be thoroughly dredged, no injury should be made to the mitral valve, aortic valve and conduction bundle.

Objective To compare the optical properties and visual quality between Tecnis ZMB00 and AcrySof ReSTOR SN6AD1 multifocal intraocular lens (MIOL) in patients undergoing cataract surgery.Methods A total of 120 patients (130 eyes) who umderwent elective cataract surgery in our hospital from March 2012 to July 2015 were selected prospectively.All patients were treated with diffractive MIOL,and divided into group A (Tecnis ZMB00 group) and group B (AcrySof ReSTOR SN6AD1 group).The uncorrected distance visual acuity (UCDVA),uncorrected near visual acuity (UCNVA),uncorrected medium distance visual acuity (UCIVA),best corrected distance visual acuity (BCDVA) and best corrected near visual acuity (BCNVA) were measured before and after surgery.The defocusing curve was drawn for analysis of the contrast sensitivity,and the postoperative visual function and survival quality questionnaire (VF-14) was used to evaluate the postoperative visual quality.Results At 1 week,1 month and 3 months after surgery,recovery of UCNVA,UCIVA and BCNVA in group A was better than that in group B (all P ＜ 0.05).At 1 week and 3 months after surgery,the recovery of UCDVA in group A was better than that in group B (all P ＜ 0.05).At 3 months after surgery,the spherical equivalent was lower in group A than group B (P ＜ 0.05).The contrast sensitivities under scotopia,photopic glare and scotopic glare of different frequencies in group A were higher than those in group B (all P＜0.05).The VF-14 score in group A at 3 months after surgery was lower than that in group B (P＜0.05).In group A,0.0 D and-2.5 D formed 2 peaks,and from-2.0 D to-2.5 D formed the platform stage,while in group B,only 0.0 D and-3.0 D formed 2 peaks.Conclusion The implantation of Tecnis ZMB00 MIOL after cataract surgery can improve the uncorrected visual acuity of treated eye,contrast sensitivities,postoperative visual function and quality of life of patients.

Objective To investigate the effects of the double J tube in treating drug -crystalline upper uri-nary tract obstruction.Methods There were 12 cases of drug -crystalline urinary tract obstruction,which were diag-nosed by CT for urinary tract obstruction.With the help of cystoscope,we retrograde placed the double -J tube in all the 12 patients who with persistently elevated serum creatinine in the next day of admission.Results Nine patients were successfully placed double J stent and serum creatinine of the patients decreased to normal rapidly.There were 2 patients with failed implantation and were with persistently elevated serum creatinine.1 patient with unilateral urina-ry tract obstruction was treated with conservative treatment and eventually cured.Conclusion Patients with drug -induced renal injury should have a routine bilateral ureteral CT scan,once they are clearly diagnosed as drug crystal upper urinary tract obstruction in them,timely placement of bilateral double J tube with the help of cystoscope,which was a simple and effective treatments.

Objective To detect the sequence of SLC29A1 gene rs1288 single nucleotide polymorphism (SNP) in advanced pancreatic cancer patients,and to explore its correlation with gemcitabine toxicity and prognosis.Methods Peripheral blood samples were collected and DNA was extracted.The segment containing SLC29A1 gene SNP (rs1288) was amplified by PCR,and then DNA sequencing was conducted to identify SLC29A1 gene SNP (rs1288).According to the sequencing results,the patients were divided into SLC29A1 gene rs1288 T→A mutation type group and wild type group.Clinical data,toxicity of gemcitabine chemotherapy,progression free survival (PFS) and overall survival (OS) between two groups were compared.Results A total of 83 pancreatic cancer patients were enrolled.Sequencing results showed that SLC29 A1 gene 1288 T→A mutation type was present in 52 patients and wide type was observed in 31 patients,so mutation rate was 62.7％.All the patients in both two groups could tolerate the gemcitabine toxicity,and no chemotherapy related death occurred.There were no statistical differences on the gender,age,CA19-9,tumor site,size and TNM stage between the two groups.There were statistically higher iucidences of leukopenia and thrombocytopenia in the SLC29A1 gene rs1288 T →A mutation type group compared to the wild type group (55.8％ vs 32.3％,P＜0.05;40.4％ vs 19.4％,both P＜0.05).Median OS and PFS in mutation type group were shorter than those in wide type group (11 months vs 14 months,P ＜ 0.05;9 months vs 12 months,P ＜ 0.05).Conclusions Advanced pancreatic cancer patients with the SLC29A1 gene rs1288 T→A mutation type had a higher incidence of adverse reaction in gemcitabine chemotherapy and a worse therapeutic effect,and thus detecting the mutation of SLC29A1 gene rs1288 point mutation may serve as a marker for evaluating the toxicity and prognosis of gemcitabine chemotherapy in patients with pancreatic cancer.

BACKGROUND: Encopresis after operation for congenital.ectopic anus can cause psychological, physiological and social ability disorders.OBJECTIVE: To treat the children with encopresis with biofeedback training so as to improve the function of post-operative defecation.DESIGN: A self-controlled trial.SETTING: Department of Pediatric Surgery, Second Clinical College of China Medical University.PARTICIPANTS: Totally 20 cases of encopresis after treatment with operation for ectopic anus,were recruited from the Department of Pediatric Surgery, Second Clinical College of China Medical University, between January 1998 and October 2004. Among them, there were 4 cases of complete encopresis, 7 cases of loose encopresis and 9 cases of blotch. All the cases were followed up. There were 9 cases of ectopic anus in the middle and lower parts, and 11 cases of ectopic anus at the high part.METHODS: The objective measuring methods of biofeedback training such as anorectal pressure and anus sphincter electromyography were used to train the patients with postoperative encopresis. After one-month self-directed training in anus contraction and defecation habit, the children received proper biofeedback training. ① Biofeedback training to strengthen the muscles around the anus twice per day. The portable biofeedback-training machine was taken home after the children patients could automically contract the muscles around the anus 3 weeks later. ② Biofeedback training to improve rectal sensitivity and coordination of anus sphincter, and repeated training in expanding saccus. A normal defecation reflex was established. Anus sphincter presented reflex contraction to prevent encopresis once the rectum expanded. ③ Defecation training was performed for 30 minutes after meals every day. ④ Electrostimulation combined with biofeedback training was performed for 10 minutes twice a day for 3 or 4 consecutive weeks.MAIN OUTCOME MEASURES: ① The maximum contraction anal pressure, vector volume, and electromyographic amplitude of external sphincter of anus; ② positive rate of anorectal contraction reflex of the children patients before and after training.RESULTS: According to actual treatment analysis, all the 20 children patients entered the result analysis. ① In middle and lower parts groups, the maximum contraction anal pressure increased from (11.87±5.61) kPa before training to (24.88±16.58) kPa after training; in high part group, they increased from (5.76±3.84)kPa to (18.18±13.71) kPa (P＜ 0.05). ② In middle and lower parts groups, the vector volume increased from (139.17±130.02) cm (cm Hg)2 to 608.10±131.06 cm·(cmHg)2, whereas in high group it increased from (117.01±74.35) cm(cm Hg)2 to (452.17±69.43) cm(cm Hg)2 (P＜ 0.05). ③ In middle and lower parts groups, the electromyographic amplitude of external sphincter of anus increased from (152.20±37.42) μV to (324.12±67.78) μV; in high part group, it rose from (114.08±51.41)μV to (266.18±49.38)μV (P ＜ 0.05). ④ The positive rate of anorectal contraction reflex improved from pretraining 55％ (11/20) to post-training 90％ (18/20).CONCLUSION: After biofeedback training, the maximum contraction anal pressure, anorectal sensitivity and the coordination of anus external sphincter, defecation habit, and contractibility of external sphincter of anus were all improved obviously, especially in those with ectopic anus in the middle or lower parts. Anus external sphincter function can be improved to the uttermost so as to cure encopresis.

BACKGROUND:As the potent, specific immunosuppressants emerge, the survival rate after intestinal transplantation is improved to some extent. However, the adverse effects of immunosuppressants and expensive treatment costs are not tolerable for many patients. Therefore, it is clinical y meaningful to choose traditional Chinese medicine which presents immunosuppressive effects. Artesunate has immune suppression effect, reduces acute rejection fol owing smal intestine transplantation, and improves the success rate of smal intestine transplantation.
OBJECTIVE:To observe the effect and action mechanism of artesunate in acute rejection after smal intestine transplantation in rats.
METHODS:Al ogeneic smal intestine transplantation models were established in the closed group of
Sprague-Dawley rats and Wistar rats, and then were randomly divided into three groups, syngenic transplantation group (SD→SD), al ogeneic transplantation group (Wistar→SD), and artesunate treatment group (Wistar→SD+artesunate 60 mg/kg per day, intraperitoneal injection).
RESULTS AND CONCLUSION:Rats in syngenic transplantation group survived for more than 10 days and they were al kil ed on day 10. The average survival of rats in al ogeneic transplantation group and artesunate treatment group was respectively (6.73±0.58) days and (8.50±0.74) days, with significant differences between the two groups (P<0.01). Histopathological examination showed that, there was no apparent rejection in syngenic transplantation group specimens, but mild, moderate and severe rejections in al ogeneic transplantation group on days 3, 5, 7. In treatment group, some specimens had mild rejection, but appeared relatively late to a low degree. Enzyme linked immunosorbent assay results revealed that, serum interleukin-2 and interferon-gamma expression levels in al ogeneic transplantation group were significantly higher than other two groups after surgery (P<0.01), serum interleukin-2 gene expression level in treatment group was also higher than syngenic transplantation group, but there was no significant difference (P>0.05), serum interferon-gamma expression level in treatment group was higher than syngenic transplantation group (P<0.05). Artesunate can inhibit acute rejection after rat smal intestine transplantation, and its mechanism may be related to inhibition effect on the secretion and expression of interleukin-2, interferon-gamma and other cytokines.

Objective To observe the clinical efficacy of JIN’s three needle therapy plus rehabilitation in treating mental retardation (MR).Method Seventy-two MR patients were randomized into a treatment group of 37 cases and a control group of 35 cases. The control group was intervened by conventional rehabilitation training, while the treatment group was treated with JIN’s three needle therapy in addition to the rehabilitation training. The modified Chinese version of Gesell Developmental Schedules (GDS) was adopted to observe the improvements in gross and fine motor skills, language, social function and adaptability, and the clinical efficacies were compared between the two groups. Result In the treatment group, the adaptability, gross motor skills and fine motor skills scores were significantly changed after the intervention (P<0.05). In the control group, the gross and fine motor skills scores were significantly changed after the intervention (P<0.05). After the treatment, there were significant differences in comparing the gross and fine motor skills scores between the two groups (P<0.05). In the treatment group, the total effective rates were respectively 93.1% and 62.5% in the mild-moderate and severe-extremely severe patients, versus 76.9% and 44.4% in the control group. There was a significant difference in comparing the total effective rate in the mild-moderate patients between the two groups (P<0.05).Conclusion JIN’s three needle therapy plus rehabilitation is an effective approach, and it can significantly improve the gross and fine motor skills and adaptability in mild-moderate MR patients.
