2.Neural differentiation of epidermal stem cells
International Journal of Biomedical Engineering 2011;34(2):126-128
The bulge of hair follicles contains a mixed population of stem cells,including epidermal stem cells,neural crest stem cells,as well as another type of stem cells which can be induced into melanocytes.Bulge stem cells have the ability to divide,proliferate and are pluripotent as other adult stem cells.The neural crest stem cells can differentiate in vitro into neurons,glia and melanocytes under proper induction.Meanwhile,it was proved that implanting these cells into the gap region of damaged nerves could greatly enhance the regeneration rate of nerve and restoration of nerve function.In this review,distribution of the stated stem cells in hair follicle bulge and their characteristics of differentiating into neurons were discussed,as well as their possible application in regenerative medicine.

Journal of Chinese Physician 2016;18(6):822-825
Objective To evaluate the effects of preoperative sleep disturbance on the consumption of propofol during the period of general anesthesia and postoperative sleep quality.Methods Sixty-five patients scheduled for elective thyroidectomy surgery under general anesthesia were enrolled in the study.According to the preoperative Pittsburgh Sleep Quality Index (PSQI) score,the patients were divided into sleep normal group (n =33) and sleep disorder group (n =32).Anesthesia was induced and maintained with propofol given by closed-loop target-controlled infusion (CLTCI).The consumption of propofol during the period of general anesthesia,postoperative sleep quality in the evening of surgery and at 24 h after operation,and the painful levels of the patients at 1 d and 2 d after operation were compared between two groups.Results The totalconsumption of propofol in sleep disorder group [(1 024.33 ±213.02)mg] was more than that in sleep normal group [(892.25 ± 242.30) mg] (P < 0.05),and the dosage of unit surface area per minute of propofol in sleep disorder group [(4.94 ± 0.80) mg/(min · m2)] was also more than that in sleep normal group [(4.45 ± 0.96) mg/(min · m2)] (P < 0.05).Each group suffered from bad sleep quality in the evening of operation,and got improvement one day later (P < 0.05).The sleep quality in sleep disorder group was improved after general anesthesia (P < 0.05).Conclusions Preoperative sleep disturbance increased the consumption of propofol in the general anesthesia.General anesthesia can improve the sleep quality of the patients who suffered from sleep disorder.
4.The application of lung protective ventilation strategy in laparoscopic surgery of obese patients
Journal of Chinese Physician 2017;19(4):622-625
With the ventilator associated lung injury (VALI) atracting more and more attention,lung protective ventilation strategy (LPVS) has gradually been applied to clinical practice.Obese patients are at higher risk in VALI for laparoscopic surgery,mechanical ventilation induced atelectasis is an important reason for low oxygen in intraoperative and postoperativen procedure.In laparoscopic surgery,high abdominal pressure causes the elevation of diaphragm,and increases airway pressure.The excessive pressure increases the amount of alveolar dead space and airway pressure,reduces lung compliance,and increases the possibility of barotrauma and colotrauma.In addition,carbon dioxide pnenmoperitoneum indces hypercapnia.Both of them influence the recovery of postoperative lung function.To optimize intraoperative management and improve the prognosis of patients with general anesthesia,the application of LPVS attracts more attention,including small tidal volume,positive end-expiratory pressure,and recruitment maneuvers,etc.However,LVPS may also cause lung injury.This article is a review on the application of LPVS in laparoscopic surgery of obese patients.

Chinese Journal of Postgraduates of Medicine 2017;40(7):612-614
Objective To explore the clinical curative effect of locking plate in elderly patients with proximal humeral fractures. Methods Seventy elderly patients with proximal humeral fractures were selected, and all patients were treated with surgical treatment. Among them, application of locking plate was in 35 cases (locking plate group), and application of ordinary steel plate was in 35 cases (ordinary steel plate group). The operation time, intraoperative blood loss, fracture healing time and curative effect between 2 groups were compared. Results The operation time, intraoperative blood loss and fracture healing time in locking plate group were significantly lower than those in ordinary steel plate group: (61.3 ± 5.6) min vs. (78.3 ± 4.2) min, (190.5 ± 11.5) ml vs. (268.5 ± 21.2) ml and (12.6 ± 1.8) weeks vs. (16.5 ± 1.5) weeks, the excellent and good rate was significantly higher than that in ordinary steel plate group: 94.29% (33/35) vs. 74.98% (26/35), and there were statistical differences (P<0.05). Conclusions The curative effect of locking plate in elderly patients with proximal humeral fractures is accurate. Locking plate can be fixed firmly, and it is conducive to early recovery after surgery.

Objective To analyze the colonization of Candida, Rhodotorula, Penicillium and Aspergillus in skin surfaces of patients with atopic dermatitis, and to assess the relationship between the four common fungal allergens and severity of atopic dermatitis. Methods Fifty patients with atopic dermatitis and 20 healthy controls were enrolled. Scales were scraped from lesional and non?lesional skin of flexural extremities of the patients, as well as from normal skin of the flexural elbow of healthy controls, then were subjected to microscopic examination and culture. Scale specimens were inoculated onto Sabouraud dextrose agar medium and cultured at 25 ℃ in a constant temperature incubator. Subsequently, suspected fungal or yeast?like colonies were collected for pure culture. Finally, fungal strains were identified according to colony morphology, color, growth speed, as well as microscopic features of spores and hyphae. Results No hyphae or pseudohyphae were found in any case by microscopic examination. Candida albicans and Rhodotorula were detected in 29(58%)and 17(34%)out of the 50 patients, respectively, and in 5(25%)and 2 (10%) out of the 20 healthy controls, respectively. The detection rates of Candida albicans and Rhodotorula were significantly higher in the patients than in the controls(χ2=6.23, 4.10, respectively, both P<0.05). Of 25 patients with severe lesions, 19(76%)and 12(48%)were colonized by Candida albicans and Rhodotorula respectively;among 25 patients with moderate lesions, 10 (40%) and 5 (20%) were colonized by Candida albicans and Rhodotorula respectively. An increase was observed in the detection rates of Candida albicans and Rhodotorula in the patients with severe lesions compared with those with moderate lesions(χ2=6.65, 4.37, respectively, both P<0.05). There was no significant difference in the detection rate of Penicillium or Aspergillus between the patients and health controls. Conclusion The colonization rates of Candida albicans and Rhodotorula on skin surfaces were higher in patients with atopic dermatitis than in healthy controls, and higher in patients with severe lesions than in patients with moderate lesions, indicating that the types of colonizing fungi are associated with the health status of skin and severity of symptoms in patients with atopic dermatitis.

Objective To investigate the changes of expression of Fas-associated proteins named Fas-associated death domain protein(FADD)and death-associated protein(Daxx)in the ischemic penumbra following transient focal cerebra ischemia in rats.Methods ①Adult male Sprague-Dawley rats were randomly divided into the sham-operated group and the cerebral ischemia model group.Rats underwent right middle cerebral artery occlusion(MCAO)for 2 h and reperfusion for 1,3,6,12 and 24 h using an intraluminal suture technique.The expression of FADD and Daxx mRNA and protein were measured with methods of immunohistochemistry.Western blot and reverse transcription-polymerase chain reaction(RT- PCR)respectively were used in the ischemic penumbra of rats.②Double-label fluorescence confocal laser scanning microscopy(CLSM)was performed to monitor FADD and Daxx intracellular location before and after ischemia.Results RT-PCR,Immunohistochemistry,Western blot experiments indicated that a very low level of FADD mRNA and protein were detected in the cerebral cortex of sham rats.The expression level both of FADD mRNA and protein increased significantly at 3 h after reperfusion,peaked at 12 h,then declined markedly at 24 h in the ischemic penumbra of model rats.RT-PCR,Immunohistochemistry indicated that a relatively high level of Daxx mRNA was detected in the cerebral cotex of sham rats.The expression level of Daxx mRNA increased significantly at 3 h after reperfusion and persisted to 24 h at a high level,whose protein had a same change of expression level in the ischemic penumbra of model rats. Immunofluorescence double-staining laser scanning by CLSM showed that the immunoreactivity of FADD was located in cytoplasm,and the intracellular translocation of the immunoreactivity of Daxx from nucleus to cytoplasm was monitored by measuring the green fluorescence after ischemia.Conclusion The transient upregulation of FADD and the persistant high level of expression of Daxx may contribute to neuronal apoptosis following cerebral ischemia/reperfusion.

BACKGROUND: Selective posterior rhizotomy has been extensively acknowledged as an effective method of relieving lower limb spasticity in cerebral palsy. However, the postoperative complications such as reduced muscle strength and imbalance of the spine are of concern among surgeons and therapists. The combination of limited selective posterior rhizotomy (LSPR) with adductor tenotomy can decrease these complications without compromising the treatment effects.OBJECTIVE: To investigate the effects of combination therapy of LSPR with adductor tenotomy on lower limb spasticity, gait and movement of the patients.DESIGN: A self-controlled trial and observational follow-up taking children with cerebral palsy as the subjects.SETTING: Orthopedic Department of First Hospital Affiliated to Dalian Medical University.PARTICIPANTS: Thirty children patients with cerebral palsy treated in the Orthopedics Department of the First Affiliated Hospital of Jilin University from January 2001 to December 2002 were recruited in this trial. They presented scissors gait, flexed knee and tiptoeing of different degree. There were 18 cases of brisk tendon reflex and ankle clonus, and 15 cases of positive Babinski' s sign. All the patients had no immobile soft tissue contracture and could either accomplish walking and crouching independently or walk with arms on assistant devices.INTERVENTIONS: The patients received LSPR of L5 and S1 dorsal roots together with bilateral adductor tenotomy. Muscle tone and strength, knee and Achilles tendon reflexes, ankle clonus and pathologic signs were recorded before and after operation. X-ray examination on lumbar spine and pelvic was also taken for detection of deformity. The patients' movements were assessed according to their standing and walking postures, standing and crouching movements before operation and on follow-up. During follow-up all the mentioned indices were recorded by reference to the original case history, hospital reexamination and correspondence with the patients.MAIN OUTCOME MEASURES: The amelioration in lower limb spasticity and grading of lower limb()movements.RESULTS: During the follow-up for six months to three years(the mean of 11 months), the patients' lower limb spasticity was decreased by 2. 5 grades. The gait was also improved with disappeared scissors gait and tiptoeing, knee flexion was improved and the patients could walk with heels on the ground. All ankle clonus and pathologic reflexes disappeared. The brisk knee reflex in 12 patients became sluggish after operation. There was no decrease in lower limb strength or permanent hypesthesia. X-ray examination of lumbar spine and pelvic showed no deformity in 9 patients after over 2-year follow-up. The upper limb spasticity, salivation and aphasia in 8 patients were also ameliorated. The grading for postoperative standing, walking and crouching-standing alternation[(4.25±0.91), (3.92±0.65) and(4.02±0.74)] wasimproved(t=2.04-2.98, P <0.05-0.01).CONCLUSION: The combination of LSPR with adductor tenotomy can effectively ameliorate lower limb spasticity and movement with decreased operative damage.
