Clinical Medicine of China 2009;25(6):596-597
Objective To study the clincial effects of of single Sialic four hexose sodium injection ganglio-side (GM1) in treating periventricular leukomalacia of premature infants. Methods 41 cases of periventricular ]eukomalacia patients were divided into GMI treatment group (n=22) and control group (n=19). The treatment group were given another GM1 treatment. Dynamic observation of changes in B-head information was conducted. Re-stilts 6 months after birth, 8 cases(36.4%) in treatment group and 13cases (68.4%)in control group occurred with ventricular dilatation (χ28.85, P<0.05). Nervous system examination revealed there were 5 cases (22.7%) in treatment group and 10 cases (52.6%) in control group with limited performance of the Board of mus-cle tone and abnormal movements (χ2 3.93, P<0.05); 4 cases in treatment group (18.2%) and 9 cases (47.4%) of control group had mild cognitive impairment and mental retardation according to nervous system sequel-ae(χ24.01,P<0.05). Conclusion GM1 can effectively treat periventricular leukomalacia and reduce abnormal movements.
3.Short-term outcomes of laparoscopy surgery for colorectal cancer: a comparative study
Fudan University Journal of Medical Sciences 2010;37(1):92-99
Objective To investigate the short-term outcomes and oncological safety of laparoscopy resection for colorectal cancer. Methods Between January 2004 and March 2009, 35 patients with colorectal cancer underwent laparoscopic-assisted surgery in our hospital, among which 32 underwent radical resection, 1 underwent laparoscopic exploration, and 2 were converted to open surgery. These patients were allocated in the laparoscopic group. Same numbers of patients who underwent conventional open surgery during the same period of time were identified and allocated in the open group. Short-term data, including surgical time, intra-operative blood loss, intra-operative blood transfusion, length of incision, histopathological data, post-operative complications and post-operative functions, were collected and compared between the two groups. Results A total of 67 patients were enrolled (32 in both laparoscopy and open groups). The other 3 cases were analyzed separately (1 underwent laparoscopic exploration and 2 converted to open surgery). The two groups were well balanced as to age, gender, and TNM staging and location of tumour. Histopathologically, the laparoscopic approach was equal to conventional approach as regard to resection margin (distal margin, 5 cm vs 5 cm, P=0.664) and lymph node yield (7 vs 8, P=0.228). This study also showed a longer surgical time (250 min vs 180 min, P=0.006), but shorter length of incision (10 cm vs 20 cm, P<0.001), less demand of intra-operative blood transfusion (1 case vs 10 cases, P=0.003), reduced use of analgesics (12 cases vs 25 cases, P=0.004), shorter post-operative stay (9.5 days vs 11 days, P=0.008) and earlier recovery of bowel function of the laparoscopic group. There was no statistical difference of intra-operative blood loss (200 mL vs 200 mL, P=0.098), incidence of post-operative complications (8 cases vs 6 cases, P=0.545) and volume of post-operative negative drainage (507.5 mL vs 669.0 mL, P=0.475) between the two groups. Conclusions Though limited by a relatively small sample size, our study showed that laparoscopy approach for colorectal cancer is equal to open approach in terms of oncological safety and short-term outcome.

Objective To evaluate the clinical effect of thrombolysis combined with prostaglandin El (PGE1) in the treatment of patients with acute pulmonary thromboembolism (APTE).Methods According to the digital table,88 patients with APTE corresponding to thrombolytic therapy were randomly divided into the simply thrombolytic group(49 cases) and the joint PGE1 group(39 cases).The simply thrombolytic group were given conventional thrombolysis,and the joint PGE1 group were given thrombolysis combined PGE1 therapy.The levels of PaO2,PaCO2,pulmonary artery systolic pressure(PAsP),cardiac troponin I(cTNI),B-type natriuretic peptide(BNP) were monitored,and the clinical efficacy was evaluated.Results After the treatment,the levels of PAsP,cTNI,BNP of the joint PGE1 group were better than those of the simply thrombolytic group(t =2.173,2.349,2.495,all P <0.05).The clinical effective rate of the joint PGE1 group was 82.1%,which was significantly higher than that of the simply thrombolytic group (59.2 %) (χ2 =5.339,P < 0.05).The critical event occurrence of the joint PGE 1 group was 7.7 %,which was significant lower than that of the simply thrombolytic group (24.5 %) (χ2 =4.333,P < 0.05).Conclusion Thrombolysis combined PGEI therapy may be more effective in reducing pulmonary artery pressure,protecting myocardia,improving the right heart function than only thrombolysis,and thus improve clinical symptoms and short-term prognosis in the APTE patients.

Objective To investigate the diagnostic value of electrophysiological examination for tarsal tunnel syndrome (TTS).Methods Motor nerve conduction velocity (MCV),sensory nerve conduction velocity (SCV),F wave and electromyographic measurements were carried out with 26 clinically suspected TTS patients.Results Of the 26,22 patients were unilaterally affected and 4 were bilaterally affected,so 30 tarsal tunnels in total were affected.All received electrophysiological examination.Of the 30 affected tarsal tunnels,abnormal MCV was detected in 28 of the posterior tibial nerves (93.3%),while abnormal SCV was detected in 27 medial plantar nerves (90%) and 24 lateral plantar nerves (80%).Needle electromyography of 156 targeted foot muscles detected abnormal spontaneous potentials in 90 of them (57.7%),giant potential in 12 muscles (7.7%) and decreased recruitment in 76 (48.7%).Conclusions The distal posterior tibial nerve is impaired in TTS,presenting axonal damage in an electrophysiological examination.Such examinations should have an important role in the diagnosis and differential diagnosis of TTS.
