1.SURFACE CYCLODIATHERMY FOR ABSOLUTE GLAUCOMA
Journal of Chongqing Medical University 1987;0(01):-
Twenty two patients with variant types of absolute glaucoma were treated by surface cyc-lodiathermy. Follow-up time averages 3.5 years, without medication, intra-ocular pressure (IOP) was well controlled in 13 patients; IOP was decreased by 50% and the symptoms were relieved in two patients. The effective rate was 68%. In this paper, the technique and comp-lication of this operation were introduced. The technique rather simple. The effect of the operation is satisfactory, and complication is few. Therefore, we adopt cyclodiatharmy is a better procedure for absolute glaucoma

Journal of China Medical University 2010;(9):737-739,742
Objective To approach a new method induce the differentiation of mesenchymal stems cells(MSC)into neuron-like cells.Methods We co-cultured Schwann cells with MSC to induce the differentiation of rat MSC into neuron-like cells.Immunohistochemistry was employed to observe the expression of NSE and Brdu,and Western blot to examine the expression of NeuN by in transdifferenciated MSC(Neuron-like cells).Additionally,we analyzed the differentiating rate of MSC.Results The co-culture of MSC with Schwann cells could induce the expression of NSE and NeuN.They have been differentiated into neuron-like cells.The differentiating rate of MSC was(80.51±5.65)%.Conclusion The co-culture with Schwann′s cells could differentiate rat bone marrow derived MSC into Neuron-like cells.

Chinese Journal of Hospital Administration 2015;(4):304-306
Objective Understanding current situation of pharmaceutical service before and since the ongoing health reform in community health institutions of China,and providing practical evidences to the government.Methods Adopting some indicators to comparative study the pharmaceutical care in 2008 and 201 1 in community health service institutions of China.Results From 2008 to 201 1, pharmaceutical service quality in general has greatly improved in community health institutions of China. For example,average number of drugs per prescription descended from 2.5 1 to 2.23.Percentage of prescriptions with an antibiotic descended from 43.98 to 32.08.Percentage of prescriptions with a hormone descended from 7.13 to 4.67.Percentage of prescriptions with two or more antibiotics descended from 1 1.24 to 7.31.These four indicators before and since the reform have statistical significance (P values are:0.003,0.001,0.003,0.004 respectively).But there are still inadequacies:from 2008 to 201 1,the average prescription cost descended from 59.63 to 5 1.18 yuan.Percentage of prescriptions with an IV drip descended from 34.84 to 30.41.These two indicators have not statistical significance(P values are 0.182,0.236 ).Conclusion To improve the quality of pharmaceutical service in community health institutions,the government should increase financial input to the community health institutions.

0.05).Phlebitis occurred in 3 cases(4.2%) in PICC group,pneumothorax happened in 2 cases in CVC group.Calhelerization failure in CVC group was 7 cases who then received PICC successfully.No deep vein thrombosis occurred in either group. Conclusions:PICC has no possible severe complications of central venous access such as pneumothorax.The new method provides a safe,reliable and effective venous access for mid and long term usage in old patients.

Objective:To investigate the effect of ultrasound-guided transverse abdominal plane block combined with dexmedetomidine on cesarean section.Methods:Eighty pregnant women undergoing elective cesarean section under general anesthesia in Binzhou Central Hospital from October 2017 to October 2019 were included in this study. They were randomly assigned to undergo either cesarean section under general anesthesia followed by patient- controlled intravenous analgesia (control group, n = 40) or ultrasound-guided transverse abdominal plane block combined with intravenous dexmedetomidine administration (observation group, n = 40). Analgesic efficacy and the analgesic effect on puerperas and their newborns were compared between the observation and control groups. Results:At 2, 4 and 12 hours after surgery, the Visual Analogue Scale score in the observation group was (2.1 ± 0.9) points, (2.2 ± 0.7) points, (3.0 ± 0.6) points, respectively, which was significantly lower than (4.4 ± 1.3) points, (4.9 ± 1.2) points, (3.9 ± 0.8) points in the control group, respectively ( t = 8.946, 7.854, 6.246, all P < 0.05). At 2, 4 and 12 hours after surgery, the comfort score in the observation group was (3.4 ± 0.8) points, (3.2 ± 0.7) points, (3.3 ± 0.7) points, respectively, which was significantly higher than (2.1 ± 0.7) points, (2.2 ± 0.9) points and (2.5 ± 0.8) points respectively in the control group ( t = 7.235, 6.130, 5.953, all P < 0.05). After surgery, the number of times the demand button of the anesthesia pump in the observation group was pressed was (8.4 ± 2.9), with the rate of patient satisfaction of 97.50% (39/40), which was significantly higher than that in the control group [13.1 ± 3.7, 77.50% (31/40), t = 7.036, χ2 = 9.347, both P < 0.05). At 1 and 2 days after surgery, the cumulative amount of anesthetics used for patient-controlled intravenous analgesia was (52.1 ± 1.9) mL and (121.7 ± 4.1) mL respectively, which were less than (63.6 ± 2.4) mL and (146.5 ± 5.3) mL in the control group, respectively ( t = 6.240 and 8.842, both P < 0.05). The score of extubation quality in the observation group was significantly lower than that in the control group [(1.3 ± 0.3) points vs. (3.2 ± 0.5) points, t = 6.664, P < 0.05]. There was statistically significant difference in cortisol content between the two groups at 10 minutes after extubation and at the time points of fetus removal, skin incision and intubation (all P < 0.05). In the observation group, the partial pressure of carbon dioxide in the umbilical cord blood was significantly reduced, the partial pressure of oxygen and the oxygenation index in the umbilical cord blood were significantly increased, and Apgar score at 1 minute after birth was significantly increased (all P < 0.05). Conclusion:Ultrasound-guided transverse abdominal plane block combined with dexmedetomidine can enhance the anesthetic effect on cesarean section, prolong analgesic time, reduce the amount of analgesics, improve the operation effect, reduce maternal stress responses, and improve maternal and infant health.

The experiment was designed to simulate active training with animal model. A dynamic and static trai-ning program for adult rats was carried out 30-60'/day, lasted from 25 to 232 days. The rats were killedperiodical1y in batches and the sections were prepared for exploring histological changes in knee and ankle areas on L/M. Degenerative cbanges in quadriceps and gastrocanemius muscles appeated by degrees aftet a period of in-tensive training. The nuclei proliferated in chains or clusters arranged in the center and the edge of thefibers. The number of nuclei for each chain or cluster could be as much as 20 or 30. Meanwhile, therewere also ischemic changes in small vessels. All these were the characteristic changes induced by mictotraumain muscles under repeated active and strenous training. In calcaneal and patellar ateas, there were changes of cartilaginous degeneration, necrosis and prolifera-tion (cartilaginous exostoses and osteophytes) too. The typical changes of enthesiopatby---degeneration, necrosis and proliferation (osteophyte) could beobserved in calcaneal tendon and its insertion area and in superior insertion atea of lower patella. The occur-rence of enthesiopathy in this experiment migbt be related to tke stress of traction force within muscle andcartilage during running in upward treadmill.
